Our mission is to cut through the noise and help you make confident, evidence-based decisions about your health. We believe that understanding why something works is the key to lasting results. So, our content is designed to help readers learn faster, think sharper, and build healthy habits better themselves. Our purpose is to bridge the gap between science and self-improvement. We aim to give readers the knowledge, clarity, and tools, but without confusion, fads, or pseudoscience. --- ## Our Philosophy Rather than generic one-size-fits-all content, our content aims to give you the foundations to design your own strategies that match your personal goals and lifestyle. Most resources give mountains of unnecessary information or oversimplify the truth. Our content aims to bridge that gap. We explain what works, why it works, and how to do it. We ensure all content is as accurate and actionable as we can. We believe that understanding something properly is what really converts knowledge into results. We aim to give you clarity at pace. Successful and long-lasting change isn't impossible. With the right knowledge, it can become methodical, measurable, and within your control. --- ## Our Approach We follow three simple principles across everything we publish: 1. **Learn Quickly**: We pack as much valuable information into as few words as possible. No fluff or filler. Just clarity at pace. 2. **Learn Effortlessly**: Written in plain English, clearly structured. We make complex ideas simple — but don't dumb them down. 3. **Learn Affordably**: High-quality information shouldn’t be expensive or exclusive. Our content is either free or cheaper than that regular cup of coffee. Learn what works. Learn why it works. Learn it for life. Be clear. Be accurate. Be practical. --- ## Our Standards - **Evidence-Based**: We only use high-quality research or scientific consensus, with transparent sources. - **Applied Science**: We don’t just explain what works — we use our knowledge and experience to explain *why*, and how you can personalise it. - **Expert-Written**: All content is created, edited, and reviewed by experienced, [PhD-qualified experts](https://www.alphabetguides.com/author/rdavies/). - **Accessible & Practical**: Short, structured, engaging, and built for quick application. Designed to be revisited. --- ## What We Write About We specialise in evidence-based guidance on health and wellbeing; examples include: - Muscle Growth and Strength Training - Fat Loss and Body Composition - Diet, Nutrition, and Supplements - Cardiovascular and Metabolic Health - Physiology and Human Performance - Rest, Recovery, Stress, and Sleep - Behaviour, Mindset, and Lifestyle Habits --- ## Why Readers Trust Us Our guides are evidence-based and expert-reviewed. - We explain the what, the why and the how - We prioritise clarity over jargon and buzzwords - We avoid fads, fashions, and pseudoscience - We update our content as the research evolves - We're an independent publisher - We're not funded by any advertisers or any companies - We use AI to support our editorial processes, not replace them - We exist to serve our readers only, not trends or sales. --- ### Diet Scoring System URL: https://www.alphabetguides.com/diet-scoring-system/ Last updated: 2026-07-12T16:13:22.000Z Each diet we review is individually scored across five different domains on a 1-5 Likert scale (i.e., no half scores), and then a rounded median is calculated for the "overall" score for the diet. Individual domain scores are available at the bottom of each review article. 1. Health benefits of the diet 2. Nutrient content of the diet 3. Weight loss and weight control 4. Feasibility: How easy it is to follow. 5. Safety profile and adverse events We only score diets that are used or promoted for general use, regardless of their original (or intended) purpose. Specialist "therapeutic" diets that are designed solely to treat specific health conditions or medical needs are reviewed, but not scored under the rubric. Diets that have therapeutic use but have been widely adopted beyond their original clinical context are scored (e.g., ketogenic, very low-calorie, MIND, DASH and TLC diet). Their therapeutic effects are still discussed in the article, but this *may* not be reflected in the overall score. --- ## Overall Score - ★★★★★ = Overall, the evidence is strong, and the diet is highly recommended for general adoption; it consistently shows benefits across multiple outcomes and is broadly sustainable with minimal trade-offs. - ★★★★☆ = Overall, the evidence is good and the diet is suitable for most people; the majority of dimensions are positive, with only minor trade-offs or caveats in one or two areas. - ★★★☆☆ = Overall, the evidence is mixed, and the diet is recommended only with caution; it may be suitable for specific populations or short-term use, but is not broadly recommended without consideration of individual circumstances. - ★★☆☆☆ = Overall, the diet offers limited benefits with notable drawbacks; practical and safety concerns limit its suitability for most people and it is not broadly recommended. - ★☆☆☆☆ = Overall, the diet performs poorly across all dimensions assessed; the evidence consistently points to harm or serious sustainability failures and adoption should be actively discouraged without specialist medical oversight. --- ## Health Benefits - ★★★★★ = Strong, consistent health benefits across two or more major outcomes, supported by three or more independent meta-analyses or five or more high-quality randomised controlled trials showing reduced disease risk or mortality. - ★★★★☆ = Clear health benefits across one or more major outcomes, supported by two or more high-quality randomised controlled trials or at least one meta-analysis with consistent results; minor inconsistencies may be present in a small number of studies. - ★★★☆☆ = Evidence of benefit is limited to short-term outcomes or biomarker improvements, rather than clinically meaningful disease endpoints. Available studies are often small, short, or lack independent replication. - ★★☆☆☆ = Evidence is inconsistent or low quality, with no reliable demonstration of reduced disease risk or improved health outcomes; findings are frequently contradictory or limited to poorly controlled research. - ★☆☆☆☆ = There is credible evidence of harm or absence of meaningful benefit; the diet is associated with increased disease risk, adverse metabolic outcomes, or other measurable negative health effects. --- ## Nutrition - ★★★★★ = The diet meets over 90% of the recommended daily allowance for over 90% of essential nutrients, includes all major food groups, and requires no supplementation. - ★★★★☆ = The diet meets over 80% of the recommended daily allowance for more than 80% of essential nutrients; therefore, no more than one supplement is likely needed to address minor gaps. - ★★★☆☆ = The diet has moderate nutritional adequacy but shows gaps in one or two essential nutrients or excludes at least one major food group, which may require adjustment or supplementation over time. - ★★☆☆☆ = The diet is likely to result in two or more nutrient deficiencies or requires exclusion of multiple major food groups, posing a meaningful risk of nutritional inadequacy. - ★☆☆☆☆ = It involves severe nutritional restriction or promotes unsafe intake levels — such as very high sodium or saturated fat, or critically low carbohydrate or fibre — inconsistent with established nutritional safety thresholds. --- ## Weight Control - ★★★★★ = Multiple high-quality studies report measurable weight loss of over 5%, sustained beyond 12 months in overweight or obese participants. Those who follow the diet are very likely to maintain a healthy body weight over time. - ★★★★☆ = Studies report moderate, sustained weight loss of around 5% over six to twelve months with reasonable adherence in overweight or obese people. Those who follow the diet are likely to maintain a healthy body weight over time. - ★★★☆☆ = Short-term weight loss of over 3% has been observed in some studies, but maintenance beyond six months is poor and regain is common in overweight or obese people. Those who follow the diet may be able to maintain a healthy body weight over time. - ★★☆☆☆ = Weight loss outcomes are minimal, trivial, or inconsistent across studies, with average losses of less than 3%; dropout rates are high, limiting the reliability of even short-term findings. Those who follow the diet are unlikely to maintain a healthy body weight over time. - ★☆☆☆☆ = The diet is ineffective for achieving and maintaining a healthy body weight and is associated with weight cycling, significant regain beyond baseline, or short-term losses that are not sustained. Those who follow the diet are very unlikely to maintain a healthy body weight over time. --- ## Ease to Follow - ★★★★★ = The diet is accessible, flexible, low-cost, and socially adaptable, with studies reporting over 70% adherence beyond six months. - ★★★★☆ = Adherence rates of 50–70% are reported; cost and planning demands are moderate. - ★★★☆☆ = Adherence rates of 30–50% are reported; cost, social barriers, or dietary restrictiveness present meaningful challenges to long-term adoption. - ★★☆☆☆ = Adherence rates are below 30%; the diet is often costly, complex, or socially limiting. - ★☆☆☆☆ = Adherence rates are below 15%; the diet is frequently described as socially isolating, financially demanding, or incompatible with normal daily life. --- ## Safety Profile - ★★★★★ = It is safe for most people, broadly aligns with dietary guidelines, and has no adverse effects. - ★★★★☆ = The diet is generally safe for healthy adults, with only minor reversible effects and no significant safety concerns. - ★★★☆☆ = The diet is generally safe but may pose risks for certain populations, including people with diabetes, kidney disease, or other vulnerable populations with pre-existing conditions. - ★★☆☆☆ = Documented adverse effects have been reported, nutritional deficiencies are common and well-evidenced, and medical supervision is recommended. - ★☆☆☆☆ = It carries a high risk of harm, with documented links to measurable health damage, nutritional deficiency, or elevated risk of disordered eating. --- ### Privacy Policy URL: https://www.alphabetguides.com/privacy/ Last updated: 2026-06-27T18:53:45.000Z Last updated: June 27, 2026 Contact Information Data Controller: Alphabet Guides (trading name) Email: [hello@alphabetguides.com](mailto:hello@alphabetguides.com) ### Introduction This privacy policy explains how Alphabet Guides ("we," "us," or "our") collects, uses, and protects your personal information when you visit our website, subscribe to our free newsletter, or become a paid member.

Therefore: - Free newsletter subscribers: Retained while you remain subscribed - Paid members: Account and subscription data retained for as long as your membership is active, and for a reasonable period afterward to handle billing queries, disputes, or re-activation, after which it will be deleted or anonymised - Transaction records: Payment and billing records retained as long as necessary to comply with legal obligations (typically 6–7 years for tax purposes); these are primarily held within Stripe - Customer support: Support emails and correspondence retained for 3 years to assist with ongoing issues and warranty matters - Inactive free subscribers: Where there is no engagement for 24 months, we will send a re-engagement message; if there is no response, we will delete the email address - Suppression records: We retain a suppression record (hashed email + unsubscribe date) for 3–6 years to ensure you are not contacted for marketing in error - Legal/tax retention: Where law requires longer retention (e.g., tax records), we will retain the necessary data for that period - Usage Data: Retained for as long as necessary for security, service operation, and improvement purposes, typically no longer than necessary for those purposes We may be allowed to retain personal data for a longer period whenever you have given consent to such processing, as long as such consent is not withdrawn. Furthermore, we may be obliged to retain personal data for a longer period whenever required to do so for the performance of a legal obligation or upon order of an authority. Once the retention period expires, personal data shall be deleted or anonymised. Therefore, the right of access, the right to erasure, the right to rectification, and the right to data portability cannot be enforced after the expiration of the retention period. ### Data Security *Technical and Organisational Measures:* We implement appropriate security measures to protect your personal data, including: - Secure data transmission using encryption (SSL/TLS) - Access controls limiting who can view your data - Reliance on reputable service providers (Ghost, Stripe) with their own robust security and compliance programmes - Secure payment processing through Stripe's PCI-compliant systems - Staff training on data protection requirements - Confidentiality obligations for all persons authorised to process personal data *Data Breaches:* If we become aware of a personal data breach that is likely to result in a risk to people's rights and freedoms, we will notify the relevant supervisory authority without undue delay and, where required, within 72 hours. Where the breach is likely to result in a high risk to individuals, we will also notify affected individuals without undue delay and provide recommended steps to protect themselves. ### Additional Information About Data Collection and Processing *System Logs and Maintenance:* For operation and maintenance purposes, our website and our third-party service providers may collect files that record interaction with our website (system logs) and use other Usage Data (such as IP addresses) for this purpose. This processing is necessary for the security, proper functioning, and improvement of our services. *Legal Action:* Your personal data may be used for legal purposes in court or in the stages leading to possible legal action arising from improper use of our website or services, or to protect our rights and interests. You acknowledge that we may be required to reveal personal data upon request of public authorities. *Information Not Contained in This Policy:* More details concerning the collection or processing of personal data may be requested from us at any time.

We do not knowingly collect personal data from children under 13, and our paid membership is not intended for use by anyone under 13\. If we learn we have collected information from a child under 13, we will delete it immediately. Note: While UK GDPR sets the age of consent for information society services at 13, some EU member states may apply higher age limits. We recommend parents and guardians supervise children's online activities. ### Cookies and Tracking *Essential Cookies* Our website (hosted by Ghost) uses essential cookies necessary for basic functionality, such as: - Session cookies to keep you logged in as a member - Security cookies to prevent fraud - Cookies required by Stripe to process membership payments securely *Native Analytics (Cookie-Free)* We use first-party, cookie-free analytics, built into our website platform and powered by Tinybird, to understand how visitors and members interact with our content. This does not use cookies or other persistent identifiers to track you across sessions, browsers, or devices, and therefore does not require separate cookie consent. When you're logged in as a member, we may record which posts you view to help improve our service and better understand what content is most engaging; this data is never shared with third parties. **Google Analytics with anonymised IP (Google Ireland Limited)** Google Analytics is a web analysis service provided by Google Ireland Limited (“Google”). Google utilises the Data collected to track and examine the use of this Website, to prepare reports on its activities and share them with other Google services. Google may use the Data collected to contextualise and personalise the ads of its own advertising network. We collect this information for statistical purposes and to improve the functionality of our website. This integration of Google Analytics anonymises your IP address. It works by shortening Users’ IP addresses within member states of the European Union or in other contracting states to the Agreement on the European Economic Area. Only in exceptional cases will the complete IP address be sent to a Google server and shortened within the US. **Personal Data processed**: Tracker and Usage Data. **Place of processing**: Ireland – [Privacy Policy](https://policies.google.com/privacy?ref=alphabetguides.com) – [Opt Out](https://tools.google.com/dlpage/gaoptout?hl=en&ref=alphabetguides.com). *How to Manage Cookie Preferences* Because we rely only on essential cookies and basic analytics cookies, there is no non-essential cookie consent banner on our site. You can manage or block essential cookies through your own browser settings, but doing so may prevent core features (such as staying logged in as a member) from working correctly. ### Changes to This Policy We may update this privacy policy periodically to reflect changes in our practices or for legal, operational, or regulatory reasons. We will: - Post the updated policy on our website - Update the "Last updated" date at the top of this document - Notify you via email if changes significantly affect your rights or how we process your data Should changes affect processing activities performed on the basis of your consent, we will collect new consent from you where required.

Our Privacy Policy at [www.alphabetguides.com/privacy](https://www.alphabetguides.com/privacy/) contains additional age-related provisions that align with these requirements. 1. **Scope of Service** Our Service provides health and fitness Digital Content (for example: fitness guides, workout plans, meal plans, and other educational materials) through two access models: - Free content: Available via our newsletter, in exchange for your email address. - Paid Membership: Premium content available exclusively to paid Members via a recurring subscription, billed through Stripe and managed via our website (powered by Ghost). We may also provide blog posts, newsletters, and promotional content to both free and paid users. Important: All Membership transactions are made directly through our website. Payment processing is handled securely by Stripe via our website's native membership integration. By purchasing a Membership, you agree to Stripe's terms of service and privacy policy in addition to these Terms. 1. **Memberships and Payment** 5.1 **Membership Process** To purchase a paid Membership, you must: - Create a Member account with a valid email address - Provide valid payment information via Stripe's secure checkout - Select a Membership tier and billing frequency - Accept these Terms & Conditions 5.2 **Payment Processing** All payments are processed securely by Stripe. We do not store your complete payment card details; this information is held directly within Stripe. By purchasing a Membership, you authorise us, via Stripe, to charge your payment method on a recurring basis according to your selected billing frequency until you cancel. 5.3 **Recurring Billing** Memberships automatically renew at the end of each billing period (monthly or annually, as selected) until you cancel. You will be charged the then-current price for your tier at each renewal unless we have notified you of a price change in advance. 5.4 **Prices and Currency** All prices are displayed in the currency shown at checkout. We may change Membership prices from time to time. If we increase the price of your tier, we will provide reasonable advance notice before the change takes effect on your next renewal; continuing your Membership after that point constitutes acceptance of the new price. 5.5 **Account Confirmation** Upon successful payment, you will receive a confirmation email containing: - Details of your Membership tier and billing frequency - Access instructions for premium content - Receipt for your records 5.6 **Access to Premium Content** Premium Digital Content is made available to active Members through our website immediately upon successful payment. Access is tied to your Member account and is provided for as long as your Membership remains active and in good standing. 5.7 **Failed and Late Payments** If a renewal payment fails, we (via Stripe) may attempt to retry the charge. If payment cannot be collected after a reasonable number of attempts, we reserve the right to suspend or downgrade your access to premium content until payment is resolved. 1. **Cancellations and Refunds** 6.1 **Cancelling Your Membership** You may cancel your Membership at any time via your Member account portal or by contacting [hello@alphabetguides.com](mailto:hello@alphabetguides.com). Cancellation stops future recurring billing. 6.2 **Effect of Cancellation** Unless otherwise stated at checkout, your access to premium content continues until the end of your current paid billing period, after which it will not renew. We do not provide pro-rata refunds for the unused portion of a billing period, except as set out below or as required by law. 6.3 **Refunds** Because premium content is accessed on an ongoing subscription basis, we generally do not offer refunds for billing periods already paid. We may offer refunds in exceptional circumstances, such as: - Technical issues that materially prevented access to premium content - Duplicate charges made in error - Where required by applicable consumer protection law 6.4 **Refund Requests** To request a refund, contact [hello@alphabetguides.com](mailto:hello@alphabetguides.com) within 14 days of the relevant charge with: - Your account email address - Date of the charge in question - Reason for the refund request 6.5 **Refund Processing** Approved refunds will be processed within 14 days and returned to your original payment method via Stripe. Processing times may vary depending on your payment provider. 6.6 **Consumer Rights** Nothing in this policy affects your statutory rights as a consumer, including any statutory right to cancel a subscription contract within a cooling-off period under applicable consumer protection legislation. Please note that if you access or download premium content during a statutory cooling-off period, you may lose the right to cancel for a refund in respect of that period, where permitted by law; we will make this clear at the point of purchase where relevant. 1. **Free Newsletter and Account Management** 7.1 **Free Subscription** To receive our free newsletter, you may provide your email address via our website. By doing so, you will be clearly informed about what you are subscribing to before providing your email address. 7.2 **Member Accounts** Whether you sign up for the free newsletter or a paid Membership, you may be asked to create a Member account.

We process unsubscribe requests promptly. Unsubscribing from the newsletter does not cancel an active paid Membership; these are managed separately (see Section 6).

Our goal is to translate the complicated research into practical guidance. We like to keep things transparent, so this page explains how we produce content, what evidence we use and how we maintain editorial independence, consistency and accuracy. 1. [**Scope**](https://www.alphabetguides.com/standards/#scope) 2. [**Our Mission & Independence**](https://www.alphabetguides.com/standards/#our-mission-independence) 3.

[**How to Cite Our Content**](https://www.alphabetguides.com/standards/#how-to-cite-our-content) 11. [**Collaborations & Contributions**](https://www.alphabetguides.com/standards/#collaborations-contributions) --- ## Scope At **Alphabet Guides,** we publish: - Free articles that summarise the best available evidence. - Premium gated articles that are designed to be practical, effective and evidence-based. - All our content is organised by topic on our [index page](https://www.alphabetguides.com/index/) and [glossary page](https://www.alphabetguides.com/glossary/) that you can browse by keyword, theme or topic. --- ## Our Mission & Independence Our editorial mission is to present clear, practical, and factual summaries of health and fitness research that help readers make informed decisions about their own lives. We maintain editorial independence from commercial interests: authors and editors make content decisions based on relevance, the quality of evidence, and reader value. We do not take money from sponsors or advertisers. All our revenue comes from our paid subscribers. --- ## Evidence Standards: What We Rely On We prioritise quality evidence and context. When forming recommendations or describing health effects, we look for: 1. Systematic reviews and meta-analyses of high-quality studies. 2. Randomised controlled trials (RCTs), if available. 3. Observational studies (cohort, case-control) that meet [Bradford-Hill Criteria](https://pmc.ncbi.nlm.nih.gov/articles/PMC4589117/?ref=alphabetguides.com) when high-quality RCTs are not available. 4. Authoritative guidelines from respected public-health institutions or professional bodies. 5. We tend to avoid mechanistic or non-human lab studies, but may use them every now and again where they may be of interest or no better evidence is available. We don't base our recommendations on single small or low-quality studies, non-peer-reviewed claims, or anecdotes. Where evidence is limited or conflicting, we apply logic, state the uncertainty plainly and avoid definitive claims. --- ## Sources & Citations - All factual claims that are not common knowledge usually include a numbered superscript citation linking to the source material in the full reference list (example1) - Transparency and accuracy are important to us. The full list of all the source material we use can be found at the end of our articles. - Where the full source material is available in another article, we may just link directly to it instead of repeating it. - We prioritise open-access, citable material like peer-reviewed articles, guidelines, and reputable public health institutions. - We try not to link to fully hidden paywalled content or secondary "recycled" sources (other than our own). --- ## Roles - **Authors:** All content is written by contributors with relevant subject knowledge (e.g., research, training, and professional experience). Where authors want to be identified, they'll be credited within the article with their contribution clearly defined (usually at the top and/or end of the article). - **Editors & Reviewers:** Editors and reviewers are responsible for verifying accuracy and completeness. Editors are there to check clarity, tone and structure of the content, and ensure that it follows our editorial standards. Acknowledgements of who did what are provided at the end of each article or guide. Content may be authored, reviewed and edited by the same expert using a structured editorial process and fixed standards. --- ## Editorial Process We select topicsbased on: - What we think readers want - What we find interesting - Where we think there's a knowledge gap - Where we think the content might fit well Authors draft content by researching the subject area and citing primary studies and reviews from [PubMed](https://pubmed.ncbi.nlm.nih.gov/?ref=alphabetguides.com) or the journal's website. Reviewers check that the content and sources are accurate. Editors then review the content for clarity, accuracy and tone. Content is then published with credits, citations, sources and a publication date. We then monitor feedback and new evidence. Content may be updated periodically where relevant and appropriate. --- ## Corrections & Updates Readers who identify errors should contact us at [**hello**](mailto:hello@alphabetguides.com)[**@alphabetguides.com**](mailto:hello@alphabetguides.com). Please provide a concise description of where the error is or a link to the article, and any relevant supporting evidence. We'll correct factual errors as soon as possible. We aim to review content at least every 24 months. The review cadence may vary by topic. For high-change fields, we may review more frequently. --- ## Conflicts of Interest & Disclosures We require all authors, editors and reviewers to disclose relevant conflicts of interest, including: - Financial relationships with companies related to the article topic. - Paid consultancies, sponsorships, or research funding. - Significant personal interests that might influence judgment. Disclosures are summarised within the article (if relevant). If a piece is funded or supported by an external organisation, we disclose that funding and explain what role (if any) the funder had in content development. --- ## Sponsorship, Advertising & Partnerships We keep editorial content separate from any advertising and commercial partnerships. Our principles are: - **No advertising within editorial content.** Any promotions are clearly labelled and located away from editorial pages. - **Sponsorships or paid partnerships** are disclosed clearly on the relevant pages. Sponsors do not control editorial content. - **Affiliate links** (if any) are disclosed and should not be the primary reason for content. If a partner or sponsor proposes content, it undergoes the same editorial process and is clearly identified as sponsored or partnered content. --- ## How to Cite Our Content If you wish to reference our material in journalism or research, please ensure that you clearly cite our work or [**contact us**](mailto:hello@alphabetguides.com) for permission to republish longer excerpts. For formal use, include the article title, "**Alphabet Guides"** as the publisher, the URL, and the publication date. --- ## Collaborations & Contributions If you want to suggest a topic for us to write about or would like to submit an article of your own, please send it to [**hello**](mailto:hello@alphabetguides.com)[**@alphabetguides.com**](mailto:hello@alphabetguides.com).

This is due to powerful biological and psychological defence mechanisms in your body. - Yo-yo dieting (“weight cycling”) is not good for your future weight loss prospects or your physical and mental health. There are ways to avoid it. Yo-yo dieting is the all-too-common and frustrating cycle of losing weight only to regain it and repeat the process, again and again and again and again. It affects a large majority of dieters attempting, or who even end up achieving, a significant amount of weight loss. This pattern isn't a personal failure or lack of willpower; it's a depressingly predictable response to overly restrictive diets, which fail to understand basic biology and human behaviour. ## What is the yo-yo diet "cycle"? “Weight cycling” or yo-yo dieting typically follows a predictable pattern: 1. Initial enthusiasm for the new diet 2. Aggressive calorie restriction 3. Then rapid weight loss 4. Followed by increasing hunger, cravings, and psychological fatigue, 5. That ultimately results in overeating and regaining the weight lost. Sometimes, it actually **exceeds** the original starting weight. The exact opposite of what you intend. Research does show that the majority of people who do yo-yo diets often end up regaining the weight, and sometimes more than those who never diet at all.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/31675146/?ref=alphabetguides.com) Weight cycling perpetuates itself because each failed attempt reinforces the belief that more extreme measures are necessary for weight loss. The inevitable regain gets attributed to personal weakness rather than a perfectly natural (but misunderstood) physiological response. It’s a “desperate times call for desperate measures” thought pattern that's ultimately wrong. This mindset creates a psychological trap where people alternate between periods of rigid control and chaotic eating. They never really develop the sustainable habits necessary for long-term change and maintaining a healthy body weight. ## Weight Cycling: The Science Behind It When you lose weight, your body activates many of biological processes that are designed to defend against what it perceives as starvation. One of these is changing your [metabolic rate](https://www.alphabetguides.com/basal-metabolic-rate/), which can decrease by 10-15% or 200-300 calories a day in response to weight loss (known as “adaptive thermogenesis”). This decrease can persist for months (or possibly years) after weight loss (and even after weight regain). This makes future fat loss endeavours more difficult. Additionally, hormonal changes can increase [hunger signals](https://www.alphabetguides.com/appetite-and-body-weight/) and encourage overeating. Together, this increases your physiological drive to eat more and more often. These aren't just short-term responses, either. A study following “The Biggest Loser” contestants found that negative metabolic and hormonal changes last for **years** after losing large amounts of weight.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/27136388/?ref=alphabetguides.com) When foods are completely forbidden, they become more psychologically attractive and trigger intense hunger cravings that typically lead to binge-eating. This restriction-binge cycle can become “self-reinforcing” (a self-fulfilling prophecy), with each new “failure” strengthening beliefs about your perceived lack of self-control. Extreme “all-or-nothing” mindsets and [severely restrictive diets](https://www.alphabetguides.com/crash-diet/) are common in weight cycling. Catastrophising perfectly normal eating patterns as a complete failure can also cause abandonment of healthy behaviours: it's the “I've blown it, so I may as well give up”. It’s that one cookie, which then becomes the whole pack. This “black-and-white” thinking prevents the development of one of the most important skills for long-term success for fat loss and weight control: **moderation**. ![Infographic depicting the weight cycling cycle.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/08/yo-yo-dieting.jpg) ## Health Risks of Weight Cycling Beyond the frustration of repeated weight regain, yo-yo dieting poses a genuine health risk. Research shows that weight cycling is associated with increased risk of disease and death (at any body weight).[\[3\]](https://pubmed.ncbi.nlm.nih.gov/25614199/?ref=alphabetguides.com) Repeatedly triggering stress-starvation responses, overeating patterns, and loss of muscle mass can lead to long-term metabolic and psychological "scarring". These changes are not only bad for health but also make subsequent fat loss attempts more difficult. Repeated failed attempts are also not good for your self-confidence and self-belief in achieving goals. It creates a sense of helplessness around body weight. Food anxiety, eating disorders, [stress](https://www.alphabetguides.com/ways-to-decrease-cortisol/), social isolation and lower quality of life can be more detrimental to your all-round health than your body weight alone. These can also persist long after abandoning diets: the mental health issues may stick around.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/29504788/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/8002684/?ref=alphabetguides.com) If dieting is affecting your mental health or you've had an eating disorder, speak to a doctor or specialist before starting a new diet or any other weight loss attempts. --- ## How to Prevent Yo-yo Dieting: Breaking the Cycle _This post is for subscribers only._ ### Big Belly But Thin Legs: The Candy Apple Phenotype URL: https://www.alphabetguides.com/candy-apple-phenotype/ Last updated: 2026-10-11T08:00:26.000Z summary - A firm, protruding abdomen paired with thin arms and legs reflects the buildup of fat inside the abdominal cavity. - Eating too much, moving too little and having low muscle mass overload and overwork your vital internal organs, causing health issues. - Reversing it requires you to change your body composition. Exercise, adequate protein and other healthy lifestyle habits are key to solving it. --- Body fat doesn't accumulate the same way for everyone. The most obvious example is how men and women put fat on differently: the classic apple shape (waist and abdomen) for men versus the pear shape (hips and thighs) for women. How and where you put on fat is determined by your hormones, genetics, and lifestyle, and it also affects your health in different ways. **Where** you store fat matters just as much as **how much** fat you carry. So, there are a few different "subtypes" of obesity. In this article, we are going to look at one of the highest-risk types, what we call "**Candy Apple Phenotype**". ## Why men get a big belly but still have thin limbs Walk around anywhere in the West, and you'll notice a very common body shape in middle-aged and older men. They tend to carry a large but firm, protruding belly that is shaped like an apple or beer keg. Yet, their arms, legs, shoulders and even face appear normal, or sometimes thin. In other words, their belly doesn't match the rest of their body.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3411490/?ref=alphabetguides.com) This has been observed for a while, often laughed off as a "beer gut" or just a sign of getting older. However, this unique type of body shape is a serious indicator that things aren't healthy inside. It's a bit more serious than just carrying a few extra pounds. What we are really seeing is a metabolic health issue. One where the muscle in those skinny legs and arms is not working well, all while you're packing dangerous fat deep inside your abdomen and around your vital organs. ### Physiology behind the beer gut With "typical" obesity, fat accumulates evenly under your skin across your entire body: arms, legs, back, mid-section and face. You can easily see and pinch this type of fat with your fingers — and it wobbles when you jump up and down. However, men with firm bellies and thin limbs have a different type of obesity. The candy apple phenotype is similar to a distinct type of obesity called "**sarcopenic obesity**", which means having high body fat ("typical obesity") occurring alongside a low amount of muscle ("sarcopenia"). Both of these things are bad in their own right, so having both of them together is doubly bad for your health. It's also sometimes referred to as "skinny-fat", "thin-fat" or "normal weight central obesity".[\[2\]](https://pubmed.ncbi.nlm.nih.gov/30065268/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/12466355/?ref=alphabetguides.com) The candy apple phenotype isn't quite either of these, as it seems to occur more commonly in men. People with it can be normal body weight **or** obese, and have a low or normal amount of muscle tissue. [It's **not** about scale weight](https://www.alphabetguides.com/beyond-the-scale/) or the amount of fat or muscle you have. It's about body shape, **where** the fat is distributed. It's where the body stops depositing excess energy in the muscle and directs it deep into the abdomen. #### The "Candy Apple Phenotype" Explained We call it this because the body shape resembles an apple on a stick, or a candy apple. The apple is the apple-shaped mid-section that's supported by thin limbs (the wooden stick). Beyond the physical shape, we call it the "Candy Apple" phenotype, as the candied apple represents something that ****should** be naturally healthy (i.e., [a fresh apple](https://www.alphabetguides.com/an-apple-a-day-keeps-the-doctor-away-a-review/)), but it is covered in something unnatural and unhealthy (i.e., the candy layer). ### How do you know if you have it? "Candy apple phenotype" isn't a formally classified health condition with a defined clinical diagnosis — it's a coined term. But there are some telltale signs that you may have **central obesity**, which is a closely related recognised condition. 1. **Waist Circumference**: Measure your waist at belly-button level: for men, 94 cm (37 in) or more signals increased health risk and 102 cm (40 in) or more signals high risk. Another useful check is whether your waist is more than half your height, which can flag risk even when your weight looks "normal". 2. **Type of "adiposity":** A belly that feels firm rather than soft and pinchable, alongside slim arms and legs, suggests much of the fat is visceral, so ask your doctor about clinical tests, since waist size alone can't show what's really happening inside. --- ## How and Why It Happens The reason why abdominal fat can increase while arms and legs don't is due to a "feedback loop" between a few different organs in your body: your muscles, liver, fat cells, [brain](https://www.alphabetguides.com/tag/brain-health/) and the abdominal cavity itself. ### Muscle is an energy sponge By mass, your muscles are the largest organ in your body by mass, but they are not just used for moving around and lifting heavy objects. You should think of muscles as a giant sponge (or buffer) for excess calories. If you eat too many calories, it has to go somewhere. If you've a lot of big healthy muscle (a "big sponge"), it can take this sugar from your blood and store it. If your muscle can't do this, either because it is too small (a "small sponge"), unhealthy or inactive (an "old sponge"), these calories will probably end up being stored as fat or possibly in worse places, which is what happens in a lot of liver diseases, muscle diseases and uncontrolled diabetes![\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8074531/?ref=alphabetguides.com) If you eat too many calories for your body to handle, it will overload your muscle, liver and pancreas, which will push those extra calories into your fat tissue through a process called **de novo lipogenesis**. Your body doesn't do this because it wants to — it is an inbuilt safety mechanism to keep you healthy. Storing extra fat is not good, but it's a lot better than dangerously high blood sugar levels. [Muscle - Alphabet GuidesBuilding and maintaining muscle depends on how you train, eat, and recover, and matters far beyond just aesthetics. This article covers muscle growth through exercise and nutrition, as well as muscle physiology and strategies for preserving strength and function as you age.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-ee19e84c-cc14-4801-9897-cd133e96dc18.png)Alphabet Guides![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1615505368758-8a3af2a4c379-9a78ec94-faea-4518-89e2-76c3c0740538.jpg)](https://www.alphabetguides.com/tag/muscle/) ### Fat cell storage capacity and spillover But this isn't the end of the story. Where does all this newly created fat go? Under normal conditions, your body stores those extra calories nicely and safely in your "subcutaneous" fat cells under your skin that are distributed around your body (e.g., arms, legs, and hips). However, the fat in these areas has a limited storage capacity.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/18816166/?ref=alphabetguides.com) Once the fat storage capacity in your limbs is full, which varies person-to-person, new fat that's created has to go elsewhere. It "spills over" into less healthy areas to store fat that aren't really designed to store large amounts. It will build up inside your abdominal cavity, around and inside your organs, where it affects how they work. Not good! It's called visceral fat. ### Why does the belly feel hard and firm? The answer probably lies in a combination of internal pressure (caused by too much fat) combined with muscle wall failure (caused by weakened muscles). ![Diagram depicting sarcopenic obesity.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/09/internal-fat.jpg) [Visceral fat](https://www.alphabetguides.com/visceral-fat/) stores itself behind the abdominal wall, wrapping tightly around internal organs. As it expands, it creates high intra-abdominal pressure, pushing outward against the abdominal muscles from the inside out. At the same time, the muscles in the front and sides of the torso are weakened as they become infiltrated with fat cells. The weakened muscle then stretches outward under pressure, forming a rigid, dome shape that's firm, but not wobbly. Most of the fat is **under** the muscle, so you can't easily pinch it with your fingers. --- ## What Causes Candy Apple Phenotype? ### Hormones Testosterone, estrogen and cortisol are the three primary hormone shifts that are behind the candy apple phenotype. [Cortisol is the body's main "stress hormone"](https://www.alphabetguides.com/what-is-cortisol/). High cortisol levels, through stress or genetics, encourage both increased fat storage and muscle wasting at the same time. So, it shifts the balance, making it more likely to end up with more fat tissue and less muscle. And what's most interesting is that this can happen "locally", meaning some of the fat tissue in your abdomen creates the conditions to make lots of cortisol there, so it can absorb proportionately more fat, compared to elsewhere in your body.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/16855188/?ref=alphabetguides.com) The second hormone change is to do with age. This is why it seems to occur a lot in middle-aged and older men. Once they reach their 30s and 40s, a lot of men experience [decreases in testosterone](https://www.alphabetguides.com/andropause/), which plays an important role in controlling how much muscle and fat you have. When your testosterone system stops working as well, it makes it more difficult to [hold on to your muscle](https://www.alphabetguides.com/testosterone-and-muscle-growth/). Add to this the fact that having too much abdominal fat can lower your testosterone levels even further. This happens because fat tissue releases more of another substance called aromatase, which goes on to convert what little testosterone you have left into estrogen! This then goes on to encourage more fat to be stored around your midsection, another doom-loop.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/10342671/?ref=alphabetguides.com) As your visceral fat cells are loaded with energy and start to expand, they send out a stress signal. So, immune cells then start to gather around these stressed fat cells and release molecules that cause inflammation. Too much of this inflammation can disrupt how your muscle functions and prevent it from growing. It also goes on to fuel the expansion of the fat in your abdomen even more. Stress, ageing, inflammation and some other unhealthy lifestyle factors accelerate it.[\[8\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4264591/?ref=alphabetguides.com)[\[9\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8977978/?ref=alphabetguides.com) [Boost Testosterone Naturally: A 10-Part BlueprintLow energy, mood, libido, training plateaus, or too much body fat?

As we said before, the different fat storage patterns between men and women are genetically determined. However, there are also specific fat storage patterns seen in other populations (e.g, "[Indian Pot-Belly](https://www.bbc.co.uk/news/articles/czjnd4rzmglo?ref=alphabetguides.com)"), which indicates that there is a genetic component to it. Scientists have argued for decades about where this trait has come from, and there is currently no clear consensus. However, most scientists do agree that the increased availability of [high-calorie food](https://www.alphabetguides.com/upfs-and-fat/) and reduced labour demands made these traits a clear disadvantage that increases your chances of central obesity and metabolic disease. ### Daily Lifestyle Triggers While ageing and genetics form the foundation, it is everyday habits that matter. Not every man who ages or is genetically predisposed to it goes on to have a candy apple phenotype! We think three main lifestyle decisions drive it. First, excess alcohol intake. Drinking too much speeds up muscle loss. At the same time, it preoccupies your liver, stopping it from processing fat. The extra calories from alcohol (and the [type of food](https://www.alphabetguides.com/ultra-processed-food-an-introduction/) you eat when you drink too much alcohol) get routed into your liver and abdomen, where they are stored as fat. This is where the "beer-belly" and "alcohol-related" fatty liver monikers come from.[\[10\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC11306502/?ref=alphabetguides.com) Second, diets high in added (table) sugar are linked to abdominal fat. Added sugars consumed in large amounts (e.g., from [ultra-processed foods](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/) and sugar-sweetened drinks) overload your liver and speed up the production of fat that gets deposited in your abdomen and around your organs.[\[11\]](https://pubmed.ncbi.nlm.nih.gov/21901024/?ref=alphabetguides.com) Third, prolonged sitting and [not exercising enough](https://www.alphabetguides.com/back-to-basics-a-checklist-for-muscle-growth/) lowers the amount of calories that you burn and exacerbates loss of muscle mass. Over time, if your muscles shrink, you go on to burn even fewer calories (at rest and during exercise), and this also reduces the amount of energy they can store. So, those extra calories go on to get stored in your abdomen.

However, there are some specific health risks linked to the candy apple phenotype.[\[12\]](https://pubmed.ncbi.nlm.nih.gov/20495292/?ref=alphabetguides.com)[\[13\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC7508031/?ref=alphabetguides.com)[\[14\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC7509947/?ref=alphabetguides.com)[\[15\]](https://pubmed.ncbi.nlm.nih.gov/26551006/?ref=alphabetguides.com) 1. **Type 2 diabetes:** inflammation, an overloaded, overworked liver, lower muscle mass and reduced capacity to remove excess blood sugar are a recipe for developing "insulin resistance" and then type 2 diabetes. 2. **Fatty liver disease:** excess calories accumulating as fat in and around your liver can lead to non-alcoholic fatty liver disease, liver inflammation, scarring and liver cirrhosis, which stops your liver from working properly. 3. **Cardiovascular disease:** the links between obesity and heart disease are well known. But even if you are normal body weight, central obesity is linked to [cardiovascular disease](https://www.alphabetguides.com/tag/heart-health/). The inflammatory molecules released from visceral fat can stiffen your blood vessels, increase blood pressure, LDL cholesterol and triglycerides. 4. **Pain and mobility:** Carrying the excess weight around your mid-section on skinny legs can increase stress on your hips, knees and lower back. Over time, this can go on to cause balance problems, risk of falls and physical frailty. --- ## How to Fight Candy Apple Phenotype _This post is for subscribers only._ ### Unilateral Exercise for Muscle Growth: Is One Leg Better than Two? URL: https://www.alphabetguides.com/unilateral-exercise/ Last updated: 2026-10-08T08:00:35.000Z summary - Each limb can usually handle more load when trained alone than when both limbs work together (called the 'bilateral deficit') - The cross-education effect makes unilateral training useful for injury, rehab and recovery. - However, unilateral training sessions are usually longer and require some extra (core) stability and balance skills, which need to be practised. Resistance training is dominated by “bilateral” movements such as squats, deadlifts, and bench presses. By contrast, “unilateral training”, where you exercise one limb at a time, generally receives less attention despite offering some unique and not well-known advantages. Unilateral training can be used to address balance, muscle imbalances, strength deficits, and potentially muscle growth, in ways that bilateral exercises cannot. Split squats, single-leg deadlifts, lunges, step-ups, single-arm rows, single-arm curls, and single-arm overhead presses are all examples of unilateral exercises, and unilateral training simply means building workouts from them. ![Infographic describing the difference between bilateral and unilateral exercise](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/08/unilateral.jpg) ## Understanding muscle “asymmetry” Whilst gym [exercises](https://www.alphabetguides.com/tag/exercise/) are usually "bilateral", everyday movements rarely require perfect symmetry when you move. Think about it: how often do you move both sides of the body the same way, at the same time? Beyond the fact that we rarely move symmetrically, things like daily activities, sports, work, and previous injuries can also create muscle imbalances on one side of the body compared to the other. Posture throughout the day (and while you [sleep](https://www.alphabetguides.com/tag/sleep/)) can also contribute to asymmetry. Unilateral training has a reputation for fixing “asymmetries” whilst at the same time stimulating muscle growth. Research has shown that unilateral training stimulates muscle growth similar to that of bilateral training.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/39794667/?ref=alphabetguides.com) 💡 The greater mechanical tension in the muscle is thought to counteract the lower amount of [anabolic hormones](https://www.alphabetguides.com/testosterone-and-muscle-growth/) released after unilateral exercise compared to standard bilateral exercise sessions. ## The Bilateral Deficit: What is it? Unilateral training also takes advantage of something called the “bilateral deficit”. The bilateral deficit is a well-documented quirk in the body’s muscular system. It's where you lift more weight **individually** with each limb (when added together) than you can when lifting the weights at the same time. Try it for yourself next time you are at the gym. See how much you can preacher curl one arm at a time (say for 10 reps). Add those numbers together. Then try to preacher curl that same amount with both arms at the same time. Most people can’t. It is **generally easier** to do 10×15kg on preacher curls on each arm than it is to do 10×30kg with both arms. The bilateral deficit varies between people and different types of exercise. But research consistently shows that the sum of unilateral maximum efforts typically exceeds bilateral maximum effort by 5-20%.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/19088771/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/27582260/?ref=alphabetguides.com) The implications for muscle growth are that when you exercise your muscles “bilaterally”, you are not maximally challenging the muscle to grow. This can also be exacerbated if you are carrying an injury or are a lot weaker on one side of your body. --- ## How Can You Train an Untrained Limb? Cross-Education Beyond improving individual limb strength, unilateral training offers more surprising benefits. Yet another quirk that scientists found is something called the “cross-education effect”. Training one limb unilaterally can actually **increase strength** in the other limb that hasn’t done any exercise at all! This is thought to happen because there's some ancient evolutionary cross-wiring in your brain. This is where the nerves controlling the other side of the body are stimulated as well, even without moving the muscle at all! That said, the strength increases that we see on the other side of the body are only 10-30% of what we see on the side that’s actually doing the exercise. We don’t see any muscle growth. As you can imagine, using the “cross-education” effect is particularly valuable for helping recover and maintain strength if you have an injury on one side of your body.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/17043329/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/28539892/?ref=alphabetguides.com) [Resistance Training for BeginnersA series of lessons on how to start resistance training for beginners.

Greater trunk (or "core") muscle activity has been shown during unilateral exercises, as it creates imbalances that your body must correct to do the movement.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/15705034/?ref=alphabetguides.com) Think about this: holding two 10kg dumbbells overhead versus holding one 20kg dumbbell in a single hand. You're holding the same weight above your head; however, the latter demands significantly greater core stability. The good news is that greater core activation potentially translates to better movement in general. This means that unilateral exercise can improve bilateral exercise performance as well. But it also applies to real-world or sports activities, which frequently require “asymmetrically” loaded movements. ### Muscle activation and training volume Whilst controversial, the distinct and unconventional quirks in unilateral training potentially also transfer to greater muscle growth. Greater loads, intensities, and volumes per limb allow each limb to reach its max capacity (and thus growth potential). If there are major imbalances on one side of the body compared to the other, the weaker side can be masked or compensated for by the stronger side. This means that during exercise, the stronger side is “overloaded” (lifting more than it should), whilst the weaker side is “underloaded” (lifting less than it should) — when in fact, it should really be the other way around. This creates a problem: the stronger side works beyond what it is supposed to (“overloaded”) while the weaker does less (“underloaded”) — the opposite of what's needed to improve balance. --- ## Programming and Practical Applications _This post is for subscribers only._ ### How to Reduce Sugar Intake: An Evidence-Based Guide URL: https://www.alphabetguides.com/reduce-sugar-intake/ Last updated: 2026-10-05T08:44:12.000Z summary - Most guidelines recommend limiting added sugar to less than 10% of your total daily calories (and ideally under 5%). - Eating too much sugar can trigger physical warning signs like tooth decay, weight gain, high blood sugar and high blood lipids. - Restructuring your food environment and replacing sugary beverages are effective ways to reduce your sugar intake. Sugar is now firmly embedded in the global food system. It adds flavour to food, improves its texture, extends shelf life, and is dirt cheap. There's a reason it's so popular and has been added to so many everyday foods. If you are not consciously tracking it, you're probably eating more than you realise! That said, not all sugars affect your body in the same way. Sugars that occur **naturally** in whole fruits, vegetables, and plain dairy foods come packaged with fibre, water, protein, healthy fats, vitamins, and minerals as well. This is why we think your focus should be on reducing "**added sugar**", rather than attempting to reduce your total sugar intake.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/28109280/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/33401825/?ref=alphabetguides.com) Fibre is a particularly important nutrient because it slows down digestion and absorption of sugar into your bloodstream. So, fortunately, most "high-sugar" [natural whole foods](https://www.alphabetguides.com/food-matrix/) (e.g., fruits and some vegetables) also come with a healthy dose of fibre. By contrast, added sugars are usually introduced during factory processing, cooking or at the dinner table. This type of sugar is rapidly absorbed into your body, offers little nutritional value, and is usually hidden from sight, so you can eat a lot of it without even noticing. Reducing sugar intake meaningfully **does not** require [complete elimination](https://www.alphabetguides.com/elimination-diet/) of it or giving up every sweet food you enjoy. Instead, we think the best way to approach it is to know what the broad guidelines are. Then tailor your intake by understanding your own food environment, tolerance for sugar, and personal preferences. Then choose effective ways to reduce your daily sugar intake. --- ## How Much Sugar Is Too Much? Understanding Daily Limits **Aim for under 10% of calories (about 50 g), ideally under 5%.** However, in addition to counting the traditional added sugars, most health organisations also count natural sugars found in food "extracts" like honey, natural syrups, fruit juices and concentrates. The difference between the sugar in a whole apple and the same amount of sugar found in apple juice is an important distinction. The sugar in the apple juice is "free", whereas the sugar found in the whole apple is mostly trapped **inside** the cells of the apple (that's surrounded by fibre). These natural "free" sugars behave (physiologically, in your body) as the added sugars do. So, when we talk about reducing "sugar", we are really talking about reducing "free" sugars rather than just "added" sugars. And we don't count the sugars found in whole, unprocessed food.[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC9966020/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/27916004/?ref=alphabetguides.com) So it's not necessarily about just how much sugar you are eating. It's really more about the **type** (and the amount) of sugar! Our main concern is reducing the intake of the "free" sugars, not the non-free or "bound" sugar that's found in whole foods. They are both sugars, but they behave very differently in your body. ### What are the free sugar intake recommendations? General recommendations for free sugar intake are less than 5-10% of your total daily calories. For an adult eating around 2,000 calories a day, that's about 25–50 grams.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/35302414/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/37019448/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/19704096/?ref=alphabetguides.com) However, these are just broad recommendations. If the rest of your diet is somewhat healthy and balanced, the amount of free sugar you can eat before it begins to measurably harm your health is a bit higher, around 20% of total calories (100 grams). To put this into context, the average American is eating around 85 grams of free sugar a day.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/19704096/?ref=alphabetguides.com)[\[8\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5916235/?ref=alphabetguides.com)[\[9\]](https://pubmed.ncbi.nlm.nih.gov/27418186/?ref=alphabetguides.com) So, under 5% is ideal for all-round health; under 10% is a good target to maintain good general health; and consistently consuming over 20% will almost certainly harm your health. #### Is the sugar in milk bad for you? Lactose, the sugar in milk, comes with protein, fat and calcium, and it produces a gentler blood sugar response than free sugar does. #### Is honey healthier than sugar? Honey (and other natural sugar extracts) are "free" sugars that trigger nearly identical blood sugar responses to table sugar. Although these sugary extracts from natural foods contain ****some** nutrients, they don't supply enough to offset the negative health impact of eating too many free sugars. --- ## Signs That You Are Eating Too Much Sugar Not everyone tracks their sugar intake so diligently. Thus, recognising some of the early indicators that you're eating too much sugar means that you can take action. Ideally, you do this before any long-term health problems start. 1. **Dental health:** The bad bacteria in your mouth strip minerals from your teeth, causing cavities, tooth pain and forming plaque. These bacteria feed off the free sugar. If you have good dental hygiene but still have dental issues, it may be a sign you're eating too much free sugar.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/35302414/?ref=alphabetguides.com) 2. **Bodyweight:** Gaining weight, particularly around the waistline, is another sign. Too much free sugar can trick your brain into eating more calories than you need. This goes on to increase [fat around your midsection and organs](https://www.alphabetguides.com/visceral-fat/), which is really bad for your health.[\[10\]](https://pubmed.ncbi.nlm.nih.gov/23321486/?ref=alphabetguides.com) 3. **Energy levels:** Regularly eating too much sugar makes it harder for your body to control your blood sugar levels. This often leaves you feeling tired, sluggish, irritable, with sugar cravings and hunger quite soon after eating.[\[11\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC9323357/?ref=alphabetguides.com) There are several clinical tests that your doctor can use to confirm whether your sugar levels are too high (or not), and if (or how) it's affecting your health (e.g., HbA1c, fasting glucose, OGTT and a lipid panel). If you suspect that your high sugar intake is negatively affecting your health, or have diabetes or take blood sugar medication, speak to your doctor before changing your diet. #### Health Consequences of Eating Too Much Sugar - Raises blood pressure, LDL cholesterol and triglycerides, increasing cardiovascular disease risk. - Increases [visceral fat](https://www.alphabetguides.com/visceral-fat/), insulin resistance, obesity and liver diseases. - Tooth decay increases pretty much with any intake of sugar. The safe upper limit is probably below 5%.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/35302414/?ref=alphabetguides.com) --- ## How to Reduce Your Sugar Intake _This post is for subscribers only._ ### Strength vs. Size: How Your Muscles Really Adapt to Training URL: https://www.alphabetguides.com/muscle-adaptation/ Last updated: 2026-10-01T08:00:08.000Z summary - Hypertrophy is the enlargement of muscle cells that you have, not new ones being created. This is what happens when you start lifting weights. - The strength gains that you get straight away (mostly) come from your nervous system working more efficiently, not your muscles getting bigger. - Over time, both your nervous and muscular systems adapt, getting bigger and stronger. However, they do this at different speeds. Muscles don't grow if they don't contract. If a muscle just sits there, passively receiving nutrients and [hormones](https://www.alphabetguides.com/testosterone-blueprint/) from your body in normal but adequate amounts, it may still lose some of its size — and it certainly won't get any larger. But getting stronger and getting bigger aren't quite the same process, and understanding the difference between them can help you train more effectively, recover better, and make steady, long-term progress. ## The Nervous and Muscular Systems The nervous system controls when, where, how long, and how forcefully your [muscles](https://www.alphabetguides.com/tag/muscle/) contract, so it's the nervous system that lays the groundwork for muscle growth. This relationship is referred to as "neuromuscular" (i.e., nerve + muscle) function. So, when your neuromuscular system becomes better and more efficient at contracting muscles, that's called a "neuromuscular adaptation." It's the reason professional weightlifters can often lift far more than bodybuilders despite having visibly smaller muscles. The neuromuscular system has two parts: the "central nervous system" (CNS) — your brain and spinal cord — and the "peripheral nervous system" (PNS), which connects the CNS to your muscles via what's called "motor neurons". A motor neuron, together with the muscle fibres it controls, is called a "motor unit," and each muscle contains hundreds of them. When your [brain](https://www.alphabetguides.com/tag/brain-health/) initiates movement, it sends a signal down the spinal cord and through a motor neuron, causing the muscle to contract — this is called a single "twitch." Enough twitches close together produce a "contraction", and coordinating contractions across muscles around a joint is a movement. Lifting light weights only requires a few motor units. [Lifting something heavier](https://www.alphabetguides.com/back-to-basics-a-checklist-for-muscle-growth/) means "recruiting" more of them. Each motor unit can only produce so much force, so the maximum weight you can lift is capped by the combined force of every motor unit available. But, in practice, you can never fully activate all your motor units at the same moment, even during a maximal lift (e.g., 1RM). ## Early adaptations: Strength without size In the early stages of a [resistance training program](https://www.alphabetguides.com/resistance-training-beginners/), your strength gains will typically outpace visible muscle growth gains. These early strength gains aren't from your muscles getting measurably bigger — they come from your neuromuscular system getting better at contracting and coordinating those muscles. This is a pattern often seen in both novice trainees and experienced athletes.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/3057313/?ref=alphabetguides.com) As coordination and movement efficiency improve (what scientists call "motor pattern" learning), you become able to contract and control your big and fast type II muscle fibres more quickly and easily, letting you produce more force, more power, and move more efficiently overall. It's a common misconception that neuromuscular adaptation is confined to these early weeks. While the neuromuscular changes happen fastest early on, adaptation continues well beyond the newbie phase, just at a slower rate.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/9109556/?ref=alphabetguides.com) This happens because the brain and spinal cord become more efficient at sending signals to the muscles, and muscles and nerves that work together often become progressively better "wired" to one another. It's like how repeating the alphabet enough times means you stop having to consciously think about it and can just do it automatically.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/12715968/?ref=alphabetguides.com) Your body also has hardwired, largely involuntary "safety systems" that limit how much force you can produce to prevent you from injuring yourself. However, as your muscles and connective tissue get stronger and movements become more familiar and less painful, you're gradually allowed a bit more freedom to produce greater forces. That's the basics of getting stronger! Beyond driving muscle growth, [improved strength](https://www.alphabetguides.com/minimalist-muscle-growth/) and movement efficiency also brings its own indirect benefits: better injury prevention, athleticism, balance, coordination, and easier everyday activities — benefits you tend to only notice once you lose them, whether to age or injury. Maintaining strength and functional capacity is also central to healthy ageing, quality of life, and independence. You're never too old to get stronger; studies have shown that even 90-year-olds can double their strength through resistance training.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/2342214/?ref=alphabetguides.com) #### Neural, Muscular or Neuromuscular: What's the difference? - Neural: Co-ordination, muscle activation, muscle fibre recruitment. - Muscular: Hypertrophy, tendon stiffness, muscle fibre type. - Neuromuscular: Power, explosiveness, strength and endurance. --- ## What Is Hypertrophy? The technical term for muscle growth is hypertrophy. So when a muscle grows and gets bigger, what's actually happening? Are the cells getting bigger? Yes. Are you growing more cells? No — muscle cells increase in size, not number. That distinction matters: hypertrophy means cell growth, while hyperplasia means the creation of **new cells**. Hyperplasia does occur in other organs and animals. But when muscle grows in human adults, **it's hypertrophy, not hyperplasia**. Hypertrophy, alongside strength gains, is the primary adaptation resistance training aims to achieve, and it results from mechanical "loading" or "tension" — most efficiently produced through resistance exercise and weightlifting. Weight training stimulates the individual muscle fibres ("myofibrils") to grow, increasing the muscle's cross-sectional area (CSA) along with its total mass and protein content. Following a solid 12-week resistance training program and a sensible diet, a typical beginner might gain 1–2 kg of muscle, with CSA increasing by roughly 5–10%.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/20847704/?ref=alphabetguides.com) The reverse process, "muscle atrophy" that occurs during disuse or illness, can happen surprisingly fast and severely, with losses of 10–15% of muscle mass and size possible over the same 12-week window. Put simply, you can lose muscle considerably faster than you can gain it. ## Myofibrillar vs. Sarcoplasmic Hypertrophy There are two recognised types of muscle hypertrophy: myofibrillar and sarcoplasmic. ![Infographic describing the difference between sarcoplasmic and myofibrillar hypertrophy.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/09/sarco-vs-myofib.jpg) - **Myofibrillar hypertrophy** involves a gain in the size and number of the small contractile proteins within the muscle, which also increases muscle strength and density. - **Sarcoplasmic hypertrophy** instead involves growth in the muscle's "non-contractile components" like the amount of glycogen, water, and various [proteins](https://www.alphabetguides.com/tag/protein/) you have in the muscle. Sarcoplasmic hypertrophy doesn't directly increase strength, but it may improve training performance by boosting muscle size, endurance, and energy storage capacity. In reality, both types of muscle growth occur together, just at different rates, and it's unlikely either can be selectively targeted through specific diets or training styles (whether that's volume, intensity, or recovery periods). ### The 3 stimulators of hypertrophy Hypertrophy is driven by three overlapping mechanisms: mechanical tension, muscle damage, and metabolic stress. 1. **Mechanical tension** is the force placed on muscle fibres during weightlifting — moving heavy weight through a full range of motion, under control, creates high tension in the muscle. This is where you can usually feel the muscle "hardening" when you flex it. This tension is what triggers the signalling pathways behind muscle growth. 2. **Muscle damage** results from microtears in muscle fibres, particularly during unaccustomed eccentric exercise, and stimulates the repair processes in your body. This includes the "growth factors" that drive muscle fibre repair and regenerate your [muscle fibres](https://www.alphabetguides.com/muscle-fibre-types/). 3. **Metabolic stress** comes from the [build-up of byproducts](https://www.alphabetguides.com/blood-flow-restriction-training/) from exercise, like lactate and hydrogen ions, along with cell swelling, after moderate-to-high-intensity training, and is also associated with stimulating growth. While all three mechanisms can contribute to hypertrophy, most researchers agree that mechanical tension is the most important of the three by far. Under normal conditions, muscle damage and metabolic stress can't signal growth without mechanical tension present alongside them — you can't really have one without the other.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/30930796/?ref=alphabetguides.com)[\[8\]](https://pubmed.ncbi.nlm.nih.gov/17326698/?ref=alphabetguides.com)[\[9\]](https://pubmed.ncbi.nlm.nih.gov/30335577/?ref=alphabetguides.com) #### Hypertrophy Recommendations - Load: 75–80% 1RM or 8–10 RM - Reps: 8–10 or near failure - Sets: 2–3 per exercise, 3–6 per muscle group - Rest: 1–3 minutes between sets, 48+ hours between sessions - Frequency: 2–3 sessions per muscle group per week --- ## Individual variation How much any person responds to resistance training varies with genetics, training history, effort, [nutrition](https://www.alphabetguides.com/tag/nutrition/), and recovery. Some people see rapid gains ("high responders"), while others progress more slowly. In practice, nearly everyone is a responder to some degree and can achieve measurable muscle growth with consistent training. ## Why this matters beyond the gym Hypertrophy is foundational to nearly everyone's fitness goals. It improves metabolic health, increases "insulin sensitivity", supports joint stability, and slows age-related loss of muscle mass (sarcopenia). In addition to the broader benefits of neuromuscular adaptation (mentioned above), it comes with better balance, coordination, and lower injury risk. Training for both size and strength is a cornerstone of long-term health and athleticism, whatever your primary goal happens to be: aesthetics, athletic performance, or simply ageing well. --- ## Practical Applications _This post is for subscribers only._ ### How Ultra-Processed "Junk" Foods Expand Your Waistline URL: https://www.alphabetguides.com/upfs-and-fat/ Last updated: 2026-10-05T08:09:17.000Z summary - Ultra-processed junk foods are designed for over-consumption through precise combinations of sugar, salt and fat, called a "bliss point". - They generally lack important nutrients like protein and fibre. But they also crowd healthy foods out of your diet. - They usually lead to rapid weight gain and contribute to deteriorating health. You're best avoiding where possible. "Junk food" and "[ultra-processed food](https://www.alphabetguides.com/ultra-processed-food-an-introduction/)" aren't quite the same term, but they overlap heavily. Both terms describe "food" products that are, in one way or another, engineered to make you eat more than you'd otherwise choose to. Understanding what actually makes these foods different from a home-cooked meal, and why your body responds to them the way it does, is the first step to eating less of them. ## What are Ultra-Processed ("Junk") Foods? The "NOVA" classification system sorts foods into four groups, with "ultra-processed" foods ("Group 4") at the bottom. These are industrial products built from ingredients rarely used in home cooking. Think breakfast cereals, packaged snacks, soft drinks, instant noodles, and ready meals, typically combining multiple additives, preservatives, emulsifiers, and flavour enhancers.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC10260459/?ref=alphabetguides.com) These "foods" are fundamentally different from minimally processed ones like frozen [vegetables](https://www.alphabetguides.com/3-healthiest-vegetables-around/) or canned beans, which undergo some processing but retain most of their original nutritional structure. **The key distinction isn't processing itself,** as methods like fermentation, freezing, and canning can preserve food and are sometimes [nutritionally beneficial](https://www.alphabetguides.com/food-matrix/). It's the degree of the industrial transformation, using ingredients you wouldn't recognise from home cooking (like high-fructose corn syrup, modified starches, protein isolates, various chemical additives) to create something closer to a food-like product than a food. "Junk food" captures much of the same territory through a simpler lens; they are: 1. Calorie-dense foods, 2. Low in essential nutrients, 3. High in [added sugar](https://www.alphabetguides.com/reduce-sugar-intake/), refined fat, salt, or artificial additives that increase palatability and shelf-life. Meeting at least two of these three criteria puts a food in "junk" territory. Cookies, crisps, fast food, and sugar-sweetened drinks and snacks are the obvious examples. Researchers have put precise numbers around these definitions, but in practice, most of us are better off simply knowing [what to avoid](https://www.alphabetguides.com/how-to-avoid-upfs/) than running a forensic nutritional analysis on every item at the supermarket. The bottom line is the same either way: these products are built to bypass your body's normal food satiety signals and encourage you to eat more of them than you otherwise would. --- ### NOVA Classification System of Ultra-processed Foods #### ****NOVA Group #1:** "Unprocessed or minimally processed foods" [Edible plants](https://www.alphabetguides.com/tag/plant-based/) or animals that remain whole or undergo minimal processing. Examples: Milk, Meat, Fruit, Vegetables, Eggs, Legumes and Grains #### ****NOVA Group #2**: "Processed culinary ingredients" Substances extracted or purified from ****NOVA-1** foods or directly from nature. Examples: [Oils](https://www.alphabetguides.com/superfood-oily-fish/), butter, sugar, salt, and honey #### ****NOVA Group #3**: "Processed Foods" Processed foods are created by combining ****NOVA-1** foods with ****NOVA-2 foods** via simple processing methods. Examples: Bread, Canned Fruit or Vegetables and Cheese #### ****NOVA Group #4:** Ultra-Processed Foods Industrially processed foods made mostly from ****NOVA-2** and ****NOVA-3 foods**, with the addition of chemically modified extracts and additives. Examples: soda, fast food, ready meals and sweets. --- ## Made for (over)consumption: "Hyper-palatability" Ultra-processed junk foods are scientifically engineered to be "hyper-palatable". They use precise combinations of sugar, salt, fat, and texture that aim to trigger reward pathways in the brain. Food companies employ teams of specialists to specifically find the "bliss point" — the exact amounts of these ingredients that optimise deliciousness, cravings, and consumption. It is this engineered hyper-palatability that triggers a stronger anticipatory dopamine-reward response than whole foods typically produce. At the same time, these products tend to strip out the nutrients that would naturally keep that response in check: [protein, fibre, and water](https://www.alphabetguides.com/volumetrics-diet/), which all promote satiety and normal eating patterns. Most of these foods are soft, easy to chew, and quick to digest and absorb, meaning they bypass the normal appetite controls in your mouth, brain, stomach, and gut. This rapid absorption also causes blood sugar and insulin to spike and crash quickly, which triggers renewed hunger soon after eating. The result is a genuine doom loop: you eat these foods, you want more of them; you eat more, you crave more still — and each cycle can require slightly more to hit the same level of satisfaction. The research bears this out directly: the more palatable, low-protein, and low-fibre a food is, the more of it people tend to eat. When eaten consistently over weeks and months, this pattern can go on to affect longer-term regulation of your appetite in the pancreas, liver, muscle, and fat tissue itself, changing not just how much you eat, but how often, and what you crave. Over time, this contributes to weight gain, obesity, [cardiometabolic disease](https://www.alphabetguides.com/tag/heart-health/), and even negative effects on [mental health](https://www.alphabetguides.com/tag/brain-health/) and life expectancy.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/32792031/?ref=alphabetguides.com) ## "Calorie Density": Why Some Foods are Just Easier to Overeat Beyond palatability, the worst offending foods are often simply "calorie-dense". They pack **500–700** calories into every 100g, compared to roughly **10–80** calories per 100g of vegetables, **30–90** calories per 100g of fruit, and **100–180** calories per 100g of lean meats. Some whole or "healthy" foods are calorie-dense too: nuts, seeds, avocado, some [oils](https://www.alphabetguides.com/superfood-olive-oil/) and meats. However, it's harder to eat a large quantity of these foods in one sitting compared to their junk food equivalents. One cookie, a large handful of almonds, or two full heads of broccoli might contain the same number of calories, but ask yourself which is easier to eat, and which you'd actually choose. It really comes down to three factors working together: **calories, nutrients, and taste**. So, if you want to lose [body fat](https://www.alphabetguides.com/tag/fat-loss/), you should aim to maximise nutrients and taste per calorie, not just minimise calories on their own. [Fat LossLosing fat and reaching a healthy weight comes down to biology, behaviour, and environment.

When people are offered ultra-processed meals, they eat around **500 calories a day more** than when offered minimally processed alternatives, gaining nearly a kilogram of weight in just two weeks. This happened despite both food offerings being matched for calories, energy density, macronutrients, sugar, salt, and fibre. The people who ate the ultra-processed foods simply ate more of them. It seems quite simple. The more ultra-processed junk foods in your diet, the more you eat, and the more weight you'll gain.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31105044/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/38418082/?ref=alphabetguides.com) ### Environmental and behavioural triggers If you're predisposed to eating junk food, and you keep it around you, you'll eat it. Simply having junk food visible increases how much of it people consume, compared to keeping the same foods out of sight. It's no accident that most junk food packaging is bright and eye-catching: colour, marketing, and placement are all designed to exploit hardwired psychological triggers that evolved to make brightly coloured, ready-to-eat foods appealing in the wild, not the supermarket aisle. Stress, boredom, and social situations can further trigger cravings on top of this. To change your relationship with junk foods, you'll need to change your environment.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/37813420/?ref=alphabetguides.com) --- ## Reduction Strategies _This post is for subscribers only._ ### Muscle Fibre Types Explained: Growth and Function URL: https://www.alphabetguides.com/muscle-fibre-types/ Last updated: 2026-09-24T08:00:52.000Z summary - There are three distinct muscle fibre types: Type I ("slow-twitch"), Type IIx ("fast-twitch") and Type IIA (also "fast-twitch") - They have different characteristics: the way they look, move, produce energy and behave, which is what differentiates them. - The type of muscle fibres you have is determined by genetics, the type of muscle they're in, and what and how much training you do. Beneath the surface of your skin lies a complex system of different types of [muscle cells](https://www.alphabetguides.com/tag/muscle/). Each type has distinct characteristics that influence how we move, respond to training, and grow muscle. Understanding the role of these muscle cell types helps explain why muscle growth differs between people — and why it even happens at all. ## What are the Different Muscle Fibre Types? Because they are long and thin, like a piece of string, human muscle cells are referred to as “muscle fibres”, and there are **two** main types: Type I and Type II. Type I is sometimes called “slow-twitch” and Type II is called “fast-twitch”. The Type II fibres (in humans) are then further divided into Type IIA and IIx, which is sometimes referred to as IIB in other mammals. They are divided like this because they have different characteristics — the way they contract, the amount of force they produce, and even the way they look under a microscope. The Type I fibres contract slowly and don’t fatigue very quickly — making them well suited for low and slow “endurance” exercise like long-distance running, cycling, or swimming. But contrary to common belief, they are only slightly smaller than the "fast" Type II fibres, and they can also grow (albeit slower than Type II). Type IIx fibres are strong and fast, and very powerful, but they fatigue quickly and also grow quickly in response to resistance training. The Type IIA fibres are somewhere in the middle of the Type I and Type IIx — think about Type IIA as the "athlete's" muscle fibre, strong but also has good endurance. Type I fibres are rich in mitochondria, capillaries, and myoglobin. This makes them highly efficient at [using oxygen](https://www.alphabetguides.com/improve-your-vo2max/) to produce energy. Hence, they are sometimes referred to as “oxidative” muscle fibres. Whereas the Type II fibres, especially Type IIx, have fewer mitochondria and capillaries, so they fatigue more quickly. That said, the Type II fibres can produce more force and power because they are slightly larger and contract more quickly.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/22013216/?ref=alphabetguides.com) 💡 ****Capillaries** deliver oxygen-rich blood to the muscles, ****myoglobin** binds and transports that oxygen directly into the muscle cells, and ****mitochondria** use the oxygen to generate the energy needed for exercise. --- ## Characteristics of Type I and Type II Muscle Fibres ![Infographic on the characteristics of different muscle fibre types.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/09/muscle-fibres.jpg) Source: [\[1\]](https://pubmed.ncbi.nlm.nih.gov/22013216/?ref=alphabetguides.com) --- ## Different Muscle Fibre Types: Variations The composition of the different muscle fibre types varies between people and across muscles and muscle groups. In response to resistance training and/or endurance training, a small amount of Type IIx can change to Type IIA. Type I to Type IIA interchange is less common, but possible. And Type IIA (not IIx) to Type I conversions only occur in response to endurance training.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/34564332/?ref=alphabetguides.com) Genetics plays the most significant role in determining muscle fibre type, so the composition of the millions of muscle fibres in different muscles and different people varies substantially. The thigh muscle of an elite marathon runner may contain up to 70% Type I (and 30% Type II) muscle fibres. Whereas a sprinter's or weightlifter's thigh may contain only 30% Type I (and 70% Type II).[\[3\]](https://pubmed.ncbi.nlm.nih.gov/4077779/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/25749440/?ref=alphabetguides.com) The same variation is seen across different muscles even in the same person! One of the muscles in the calf (*soleus*) can contain up to 80% Type I fibres, whereas another calf muscle (*gastrocnemius*) contains only half that amount. Different fibre types also have varying potential for growth. This is why different muscles (and different people) respond differently to the same training. Some muscles grow quicker than others. The mixture of Type I and Type II fibres in each muscle **isn’t** just random or homogeneous across the entire muscle. Different regions of the **same** muscle have distinct fibre types. For example, deeper layers in the muscle (closer to the bone) may have a higher amount of Type I fibres. Whereas the muscle near the surface of the skin has more Type II fibres. Confusingly, there are also “hybrid” fibres, which contain a mixture of both Type I and Type II components. We'll leave it at that for now. --- ## Muscle Growth & Muscle Fibre Types Understanding muscle fibre types can help you train more effectively. Whenever you move, the nervous system “recruits” (or contracts) the amount of muscle fibres it needs, based on how much force is required. It's similar to supply and demand in economics — in muscle biology, it's called 'the size principle'.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/14328454/?ref=alphabetguides.com) Lifting a very light weight only a few times “recruits” a small amount of muscle fibres, mainly Type I first. Whereas lifting a heavy weight, with high effort, “recruits” a lot of the muscle fibres almost immediately — both Type I **and** Type II. But lifting a light weight, a lot of times, with a lot of effort also recruits a lot of muscle fibres — **both Type I first and then Type II if and when needed**. This means you don’t always need heavy weights to activate those Type II fibres — but you do need a lot of reps and effort, usually by pushing close to failure. So if you want to [optimise muscle growth](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/), either lift heavy or take light weights close to failure #### What is the Size Principle? Muscle growth depends on recruiting as many muscle fibres as possible. According to the size principle, small fibres are recruited first, then followed by larger fibres as effort and fatigue start to increase. Heavy loads recruit more fibres, but low loads taken to failure also recruit more fibres. Muscle growth is only stimulated when the fibre is "recruited" (or working). So, heavy weights or high-rep sets to exhaustion ensure nearly all muscle fibres are stimulated to grow.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/33433148/?ref=alphabetguides.com) --- ## Summary Three distinct muscle fibre types exist: Type I (slow-twitch), Type IIA, and Type IIx (fast-twitch). Each fibre type has different characteristics for contraction speed, force production, fatigue resistance, and growth potential. The distribution of the different fibre types in your muscle depends on your genetics, what muscle you're looking at, and what training you're doing. Endurance athletes tend to have more Type I fibres. Power athletes tend to have more Type II fibres, though composition can change slightly with training. So, understanding recruitment patterns can be used to optimise training. Light weights recruit mainly Type I fibres, while heavy weights or training to failure recruit both Type I and Type II fibres for maximum growth stimulus.

This is known as the "food matrix" and can affect nutrition and your health. - An intact or whole food matrix can slow digestion, control your appetite, and feed the "good" gut bacteria in your gut. But it's not always good! - Smart cooking techniques and preparation methods that alter the food matrix can sometimes improve nutrient uptake. Check the nutritional labels on the back of the food packaging. Carefully weigh the food to the nearest gram to make sure you're getting the right amount of calories and macros. Check the fat and carbs to make sure you're meeting macro targets. Or check the back to check you're getting enough vitamins and minerals. This is what we've been told for decades. Judge a food by its nutrition label. We assume the label tells us everything, and only things that count are things that are counted on the label: the calories, the grams of protein and the milligrams of vitamins, right? The "label only" approach treats food as a sack of chemicals. It assumes that the nutritional "value" of the food is just the sum of its individual nutrients. If this is true, 20 grams of fat from butter should have the same effect on your body as 20 grams of fat from hard cheese. And the sugar from 2 oranges should behave like the sugar from a glass of orange juice. It would be great if nutrition were this simple. However, it's not. It misses an important part of the puzzle: the "**food matrix effect**". ## What is the Food Matrix Effect? The food matrix is the natural physical structure of your food. It's the way all of its different parts of the food are joined together. When you eat whole food, your body isn't just digesting (and absorbing) the individual ingredients or nutrients on the label; it has to deal with the entire food matrix: a unique three-dimensional structure that contains hundreds of different things in it. Imagine it like this. If you were to take all the [things that are in an apple](https://www.alphabetguides.com/an-apple-a-day-keeps-the-doctor-away-a-review/): the fibre, the sugar, the vitamin C, the potassium, the lignin, the cellulose, the compounds that give it its colour,and mix them in some water, you wouldn't have anything like an apple. The apple only exists because of the waythat those individual parts are organised and connected. The individual nutrients in the apple are locked inside the apple's cells, lattices, or connected to other things. This is the food matrix. [\[1\]](https://pubmed.ncbi.nlm.nih.gov/30040431/?ref=alphabetguides.com) So, is the food matrix good or bad? The answer is neither. It can be good or bad. It depends on what food you are eating, and what nutrients you are trying to get from the food. It can work in your favour or against you. There are good things in the apple. But there are also not-so-good things. The food matrix can prevent you from accessing the good things, but it can also protect you from the bad things. It also depends on the person who's eating the food and what they are eating it for. The stronger food matrix in whole-grain foods may be good for keeping [blood sugar levels under control](https://www.alphabetguides.com/fasting-and-diabetes/) in a person with type 2 diabetes. However, this wouldn't be favourable for an endurance athlete trying to refuel during or in between training sessions. You can choose to keep the food matrix "intact", naturally alter it yourself, or just remove it entirely. However, the state of the food matrix can actually determine how healthy it is, maybe just as much as the actual nutritional content of the food. So, understanding how it works and how to change it in your favour can be good for your nutrition and long-term health. --- ## Food Matrix: The Good and the Bad ### The good: whole foods first approach The food matrix in whole foods can work in your favour to affect how well (and how quickly)you digest and absorb the nutrients from food. For example, the "actual" calorie content of nuts (i.e., what your body takes in and uses, called "metabolisable" energy) depends on how intact their food matrix is. 💡 One hundred grams of whole almonds contain about 10% less "metabolisable" energy than roasted almonds, 12% less than chopped almonds, and 22% fewer calories than almond butter.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/27713968/?ref=alphabetguides.com) Put another way, 100 calories of whole almonds contain the same energy as 100 calories of pure almond butter (i.e., with no other ingredients). However, if you eat whole almonds, your body absorbs 22% fewer calories. That isn't mentioned on the back of the pack, is it? How? Well, this is the food matrix in action. In whole almonds, a larger amount of fat remains trapped inside the food matrix and is not absorbed into your body. Whereas, if those same almonds are ground into butter, the food matrix is destroyed, meaning more fat is absorbed. Something similar is seen when you compare some whole fruits to their fruit juices (e.g., orange and apple juice). The intact food matrix in the whole fruit slows down digestion, releasing sugar slowly into your bloodstream rather than all at once.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/6259919/?ref=alphabetguides.com) Another example is dairy food. For years, doctors and dietitians recommended limiting full-fat dairy because of its saturated fat content. However, despite its saturated fat content, large studies kept finding that full-fat dairy products, particularly fermented dairy (e.g., cheese and yoghurt), did not meaningfully raise cholesterol.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/26011901/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/28404576/?ref=alphabetguides.com) It seems that the fat in full-fat dairy, some of the calcium, saturated fat, protein and other substances bond and form their own unique food matrix in your gut, so not all of the saturated fat is absorbed by the body. Again, the food label says one thing, but what your body actually absorbs is another thing. This is the food matrix at work. And it has left a lot of doctors and dietitians scratching their heads. ### The bad: The "collapse" of the food matrix in ultra-processed foods One of the issues with ultra-processed foods is **not** justabout the bad things that they contain, like added salt, sugar, fat or artificial ingredients, but it's also about the collapse and complete removal of the food matrix. Big food companies use industrial processes to remove the food matrix and then recombine the raw ingredients back into soft, calorie-dense, tasty products that you can eat a lot of. When the food matrix is removed, you don't need to chew as much; the food is digested and absorbed more easily and quickly, and you don't get the ["I'm full" signal](https://www.alphabetguides.com/appetite-and-body-weight/). This means you can eat more of it without feeling as full.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/31105044/?ref=alphabetguides.com) We have several other articles on what ultra-processed foods are, the health risks of eating too much of them and how to avoid them in your diet if you want to read more.

It's all about context While preserving the food matrix is usually good for your health, there are some cases where removing or altering the matrix can be good. This is usually where your body needs a lot of nutrients very quickly. For athletes, there may be certain times when they need to get nutrients into their bodies very quickly (e.g., protein, carbohydrate, caffeine). Powders, pills, drinks and gel products don't have a complete food matrix, which means the nutrients in them can pass through the stomach and gut easily and into the body quickly. A long-distance cyclist wants to get the energy (carbohydrates) to the working muscles as quickly and easily as possible. They don't want parts of the food matrix overloading the digestive system while their muscles are working at full capacity.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/12617691/?ref=alphabetguides.com) There may also be certain circumstances where removing or altering the food matrix can improve nutrition and health. For example, for people who want to gain weight, frail older adults, or people with gut health problems. For these people, the food matrix can be altered with simple food preparations and cooking methods to improve the digestion and absorption of some nutrients. [\[8\]](https://pubmed.ncbi.nlm.nih.gov/32806532/?ref=alphabetguides.com) --- ## How to Make Food Matrix Work in Your Favour: Practical Application Sometimes you want to keep the food matrix, sometimes you want to remove it, and sometimes you may just want to alter it or partially remove it. _This post is for subscribers only._ ### Health Benefits of Legumes: Just One Can a Week URL: https://www.alphabetguides.com/legumes-and-health/ Last updated: 2026-09-18T15:56:15.000Z Legumes are probably the most undervalued and underappreciated food sitting in the back of your cupboard. They are pound-for-pound probably the single healthiest whole food around: only a handful of other foods come close. One of our recommendations to fix the [Western diet](https://www.alphabetguides.com/western-diet/) is to buy (at least) one extra boring standard can of chickpeas, lentils, black beans, kidney beans, or whatever legume is local to you, every single week. If you don't want to, you don't need to soak or cook anything from scratch. Just open the tin, rinse the beans in a colander, and eat them across the week. Stir them into bolognese, chilli for taco or burrito fillings, mix them into soups and salads, or mash them into a spread for toast. ### Can it be that simple? Since the Second World War ended, a substantial dietary transition has taken place in the West. The Western diet is now based on refined grains, [ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/), animal products, added sugar and numerous other artificial ingredients. These changes have led to widespread shortages of several essential nutrients, particularly dietary fibre, and several essential vitamins and minerals. And it's no surprise that rates of diseases have risen as well (e.g., type 2 diabetes, hypertension, obesity, heart and gut diseases), and continue to rise. So, we believe one of the easiest solutions is to eat more beans. Specifically, just buy and eat at least one standard can (around 400 grams, 240 grams or 3×80g servings once drained) of legumes once a week. Adding 3 extra servings of legumes a week to your diet addresses several common nutritional gaps at the same time. They are also cheap and great for the environment. --- ## Legumes in the West: A History Legumes are not a new thing; they are one of the oldest cultivated crops on Earth, and they were once a staple of the [Western diet](https://www.alphabetguides.com/tag/new-western-diet/). The Romans ate them. So did the Native Americans. For most of human history, people around the world have relied on them as a staple food. They were valued because they stored well during cold winters, provided lasting energy for physical work, and served as a cheap, reliable source of [protein](https://www.alphabetguides.com/tag/protein/) when meat was scarce or too expensive. However, as the West industrialised, that changed. Grain and meat production was scaled up, processed food technology improved, and supply chains expanded and became more reliable. So, legumes lost their place on the dinner table. Legume intake has fallen across Western countries to historically low levels. In Europe and North America, average legume intake is 10-30 grams a day; that's less than half of what we should be eating (as a bare minimum!). This change is unique to the West, as nearly all other regions around the world still consume legumes as a normal weekly (sometimes daily) staple.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/35956258/?ref=alphabetguides.com) Part of the reason for their decline was their perception across the West. For some reason, they picked up a reputation as a "poor man's food". They were perceived as something you ate only when you couldn't afford meat. However, the nutrition (and thus the health outcomes) was completely ignored. Adding more legumes to the Western diet isn't really a change; it's a revival! --- ## Legumes: Nutritional Content Legumes pack a huge amount of nutrition into a small, low-calorie package. They are low in total fat, low in saturated fat and cholesterol-free. A quarter of their dry weight is protein. That protein is "lysine-rich", which means it "[complements](https://www.alphabetguides.com/plant-based-protein/)" lysine-deficient grain and cereal proteins. This means that adding them to your diet improves the quantity andthe quality of the protein in your diet.[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4608274/?ref=alphabetguides.com) They also contain some essential minerals and vitamins that are missing from the Western diet, like: - Folate (Vitamin B9) and non-heme iron that are particularly important nutrients for women and girls. - Magnesium and potassium, which are important for keeping blood pressure under control. - Fibre, resistant starch and low-GI carbohydrates that are good for your blood sugar levels, energy levels and gut health. - They are also packed with "phytonutrients", which help lower cholesterol and inflammation (e.g., polyphenols, saponins, phytosterols).[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6266829/?ref=alphabetguides.com) --- ## The Health Benefits of Legumes ### Cardiovascular and heart health [Heart disease](https://www.alphabetguides.com/tag/heart-health/) is the leading cause of death across Western nations, and legumes have protective effects for your heart. People who eat legumes generally have a lower risk of heart disease.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/36411221/?ref=alphabetguides.com) Adding legumes to your weekly diet has been shown to lower cholesterol, lower "bad" LDL cholesterol, blood pressure, blood lipids, blood sugar levels and inflammation. The optimal amount for heart health was about 400 grams (or 2 cans) a week.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/36411221/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/37288088/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/36411221/?ref=alphabetguides.com) ### Metabolic health and body weight Because of their fibre, protein and low-GI carbohydrate content, legumes are slowly digested. This prevents spikes in blood sugar and insulin after eating them. So, adding legumes to your diet can lower blood glucose levels and improve insulin resistance over time.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/37288088/?ref=alphabetguides.com) Legumes are also filling and have [low-calorie density](https://www.alphabetguides.com/volumetrics-diet/), so they can support healthy body weights. But for weight loss, you may need to eat more than the minimum amount we recommend (i.e., over 3 servings a week). Eating around one serving of legumes **a day**led to measurable weight loss (about half a pound a month).[\[7\]](https://pubmed.ncbi.nlm.nih.gov/27030531/?ref=alphabetguides.com) ### Gut health The fibre-resistant starch found in legumes stays intact through your digestive system and goes on to feed your gut bacteria. In return for this, the "good" bacteria in your gut produce "short-chain fatty acids" and other substances that are beneficial for your health, such as:[\[8\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC9100130/?ref=alphabetguides.com) - Reducing inflammation and protecting your cells - Improving your gut strength and gut function - Lowering blood pressure and cholesterol - Potentially lowering colorectal cancer risk[\[9\]](https://pubmed.ncbi.nlm.nih.gov/33541169/?ref=alphabetguides.com) --- ## The Benefits of Eating Legumes: Beyond Nutrition While the health benefits of adding legumes to your diet are pretty solid, there are a few other positives that go in their favour, which are worth mentioning. ### #1\. Environmental impact Unlike most commercial crops, legumes have their own bacteria in their roots, which pull in nitrogen (and other nutrients) from their surroundings and "fix" it in the soil. They are natural fertilisers that regenerate the soil. This means that farmers need less fertiliser to grow them (or the other crops they're rotated with), which lowers their "environmental footprint" (i.e., lower carbon and nitrogen dioxide emissions and water use).[\[10\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC11104268/?ref=alphabetguides.com) ### #2\. Food security and locality Because legumes need less fertiliser and regenerate the soil they're grown in, they're a genuinely sustainable crop that can be grown locally rather than being imported. They are a resilient and diverse crop. Different varieties can be grown across every region of the West, from the cooler Northern regions (e.g., lentils and peas) to the warmer arid ones (e.g., chickpeas and beans). This means all Western regions can grow and buy them locally, supporting food security and farming communities in their own regions. After being harvested, they can also be dried or canned and then stored for years, making them a reliable staple that can act as a buffer for local supply chain interruptions. ### #3\. Cost Pound-for-pound, legumes are one of the cheapest sources of protein around at just a couple of pence or cents per gram of protein. And this is before you've counted the other nutrients in them as well. A single serving of beans from a can can contain 20 grams of protein. When you consider all the nutrients, they are probably one of the most nutrient-dense foods on the planet. You don't have to compromise your nutrition or your health if you need to reduce your food budget. High-quality food doesn't have to be expensive. #### Beans, beans the musical fruit ... You probably know the rest of the song. However, people's perception of the flatulence of eating beans is generally exaggerated. Although some gas and bloating have been reported when people add more beans to their diet, this tends to disappear after a week, as your body adapts to them. If you want to minimise gas and bloating, you can steadily increase the amount of beans you eat over a couple of weeks.\[[11\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3228670/?ref=alphabetguides.com) ### #4\. They're tried and tested Legumes were previously a large part of the healthy Western food system for centuries. They can be grown, harvested, processed and supplied at scale. They can (and have) been embedded into Western food culture where there's a will (beans on toast, anyone?). This can be done again. Look at how other countries have done it: - India has **lentil** **dhal** and rice. - Mexico has **beans** and corn tortillas - Asia has **tofu** and rice dishes - Africa and the Caribbean have **beans** and rice dishes - China has eight-treasure (**bean**) porridge It is a common myth that legumes are bland, boring and tedious to prepare. To promote intake, they should be thought of as flavour carriers as they readily absorb herbs, spices and other flavours. They are flexible and fit in with almost all cuisines from around the world. --- ## Making the Habit Stick There are a few ways to make our at least 1-can-a-week recommendation stick. _This post is for subscribers only._ ### Beyond Diet & Exercise: 5 Hidden Keys to Fat Loss URL: https://www.alphabetguides.com/fat-loss-beyond-diet-exercise/ Last updated: 2026-09-15T09:06:55.000Z summary - Environment and habits drive your behaviour. Modifying your food environment and social settings can support fat loss. - Genetics, personality traits, and daily rhythms (“chronotype” and “meal timing”) can also influence fat loss. - Decision fatigue and life demands can also undermine weight loss, so simplify or automate decisions where you can. Research shows that different people can respond differently to identical diet and exercise programmes. Some people can lose a significant amount of fat, while the next person sees minimal results despite (ostensibly) doing the same things. If fat loss and maintaining a [healthy body weight](https://www.alphabetguides.com/tag/fat-loss/) were only about adjusting your calories in and calories out, this would not be possible. Two different people on a strict 500-calorie deficit should lose the same amount of weight, right? We know this doesn't happen, so there must be other things involved.[\[1\]](https://www.ncbi.nlm.nih.gov/books/NBK221839/?ref=alphabetguides.com) Different responses are partly due to genetic factors, but environmental and psychological factors play equally important roles. Your physical surroundings, social networks, daily routines, and the mental “frameworks” you use in everyday life influence your [food choices](https://www.alphabetguides.com/tag/diet/) and eating behaviours in ways that traditional diet advice rarely considers. The impact of these “outside influences” often surprises people who assume that willpower and motivation can override everything and are the sole determinants of your body fat levels. But changing some of these "outside influences" can be more effective than motivation and willpower alone. Making small, easy changes can also eliminate (or reduce) the need for constant self-control, which usually eventually ends up derailing weight loss efforts in the long-run.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/29592652/?ref=alphabetguides.com) --- ## #1\. Your Environment Simply moving healthier foods to eye level in your refrigerator and cupboards, and placing less healthy options in harder-to-reach locations, can improve food choices without conscious effort: this is known as “**choice architecture**".[\[3\]](https://pubmed.ncbi.nlm.nih.gov/27185414/?ref=alphabetguides.com) Check what foods are visible and within easy reach in your kitchen. The best place for the [ultra-processed junk food](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/) is in the dustbin. The second-best place is hidden away. The third-best is on show. The least best is inside you. Just reverse the order for [nutritious, healthier food](https://www.alphabetguides.com/tag/nutrition/) options (i.e., make them easy to see, grab and eat). You can do the same for your other food environments if necessary: keep healthy snacks in your car, office desk, plan meals out for healthier options, and shop the healthier sections of the grocery store first.[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3165028/?ref=alphabetguides.com) ## #2\. Your Social Life Obesity can "spread" through social networks. People generally have an increased risk of obesity if a close friend or family member is obese. Obese pet owners are more likely to have obese pets. But at the same time, supportive relationships can **improve** fat-loss prospects through accountability, shared activities, and normalising healthy behaviours and activities.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/17652652/?ref=alphabetguides.com) Consider joining groups or communities aligned with your fat loss goals to expand your support network. There are red and green flags in your social environment too: - Look out for peer pressure and copying the eating behaviours of your social circle (i.e., “social learning”). - Be conscious about where, what and how much you eat whilst socialising. - Think about how conversations and comments around body image and how health priorities are framed when you talk about it with other people. - Reflect on what type of gifts and treats you or other people give or receive. What behaviour is it encouraging? All of these can be positive or negative. Having a neutral or (a better) "fat-loss-friendly" environment may help your efforts, for example: - Suggest healthier restaurants or ones that have healthy options available - Bring healthy dishes or offer to cook yourself at social gatherings - Be polite but firm with food pushers Tip the odds of success in your favour. You should put your own health first. ## #3\. Your Personality Traits and Individual Responses Some personality traits appear to play a role in losing fat (and maintaining it) successfully. It's probably not surprising that organised, self-disciplined, goal-oriented, dependable people who can control their behaviour (i.e., “high conscientiousness”) have lower obesity rates.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/21744974/?ref=alphabetguides.com) Other personality traits are less strongly related to obesity, but there’s some evidence that certain characteristics give different results to specific fat loss interventions, for example: - People with high “neuroticism” (i.e., people who regularly experience negative emotions like fear, anger, shame, envy, depression and low stress resilience) may respond better to more intrusive and structured programmes. - High "conscientious" people may have better outcomes with structured methods such as meal planning, tracking, and clear guidelines. - Extroverted people may respond better to group-based or "multi-prolonged" fat loss programmes (i.e., doing lots of different things at the same time) with social accountability. - Introverts may find "self-directed" methods more effective and sustainable (i.e., take charge of planning, executing, and evaluating their programmes themself). - “Open” personalities may prefer varied or flexible approaches to prevent boredom. That said, there's **little evidence** to suggest that fat loss programmes can successfully be tailored to certain personality types. There may be some strategies that you can use to your advantage, rather than a cookie-cutter “one-size-fits-all” approach.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/23176713/?ref=alphabetguides.com) We can't determine your personality, but reflect on your own experiences and recognise that your own natural behaviour patterns can potentially help match interventions to personality traits in order to improve outcomes. But be aware that tailoring fat loss programmes to your personality can carry risks if it's used as an excuse to avoid change or to justify bad habits. Personality should be seen as a guide for choosing “which” [fat loss strategy](https://www.alphabetguides.com/3-underrated-ways-to-lose-fat/) may be best, not as a limiting belief or a justification for taking the easiest option. ## #4\. When You Eat Eating larger portions earlier in the day is generally better for fat loss than eating most of your calories in the [evening or late at night](https://www.alphabetguides.com/eat-for-better-sleep/). However, the optimal timing of when you eat varies based on your waking hours (“chronotype”), work schedule, and other lifestyle factors (e.g., life demands, family, living arrangements and other duties). You can experiment with different eating patterns to identify what works best for your natural rhythms and personal schedule. Some people function better with larger breakfasts or lunches and lighter dinners. Other people prefer smaller, more frequent meals throughout the day. Some people like eating just [one (large) meal a day](https://www.alphabetguides.com/types-of-intermittent-fasts/)! You can track energy levels, [hunger](https://www.alphabetguides.com/appetite-and-body-weight/), and how well you follow your new dietary pattern, rather than just rigidly following generic timing recommendations that may not suit your individual biology and lifestyle. Trying to recall your feelings, emotions, and even what you eat is notoriously inaccurate, so track it as you go.[\[8\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC9605877/?ref=alphabetguides.com) ## #5\. Cognitive and Psychological Factors "Decision fatigue" can lower self-control and increase preferences for “default options” (i.e., reach for what’s available, what you can see, and what you're used to eating), which are often the [convenient, calorie-dense foods](https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/). This can explain why many people start the day with healthy intentions but end up making poor food choices by evening, when your cognitive resources are low.[\[9\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6119549/?ref=alphabetguides.com) The average person can make hundreds of food-related decisions every day, from what to eat for breakfast to whether to finish everything on their plate. Each decision represents an opportunity for "failure" unless you've automated some of them. Successful fat losers (and "maintainers") often report using "systems" that minimise daily food decisions. Examples include batch cooking, having set standard meals (e.g., taco Tuesday or [fish Friday](https://www.alphabetguides.com/superfood-oily-fish/)), pre-prepared frozen meals, and ready-to-eat snack options available. The aim is to reduce the number of decisions you have to make every day.[\[10\]](https://pubmed.ncbi.nlm.nih.gov/18444745/?ref=alphabetguides.com) [Fat LossLosing fat and reaching a healthy weight comes down to biology, behaviour, and environment.

Stop eating eggs. Stop eating butter. Stop eating red meat. Stop eating bacon. Stop eating carbs. Stop eating processed foods. It goes on and on and on. . It's quite understandable why it's like this. It's simple. It makes sense. It follows logic. But it rarely works. If your cholesterol is too high, you just need to be told by a doctor to eat less cholesterol; you'll follow that advice, and then everything will be fine. Or if you're overweight, your doctor just needs to tell you to eat less food, and you'll follow that advice, and you'll then be able to maintain a healthy body weight for the next 60 years. No problem. Is it that easy, right? If it were that easy, Hippocrates would have eliminated obesity 2,500 years ago. If all we had to do was say "stop doing" something, we'd have no crime, no speeding tickets, no puppy training classes or weight loss medication. Banning, barring, eliminating or restricting doesn't seem to be enough by itself (in our opinion). Trial after trial, both in the lab and in the real-world, have shown that elimination-focused diets and dietary advice do not have a good record of compliance. They *do* work in some specific cases, but we see little evidence of them working universally. Maybe there is a better way? Instead of fighting hard-wired human biological instincts with willpower, silly games and mind tricks, why not try to align human behaviour and human physiology together? In this article, we'll set out some of the theory behind why we think focusing on what to eatis better than focusing on what to avoid. --- ## Reason #1\. People Hate Being Told What (Not) to Do ### "Additive bias" People don't like restrictions or being told what to do. Especially if the consequences aren't immediate, obvious or severe. Think about the last time you gave (or received) advice from someone. Did they tell you to *start* doing something (i.e., "take this", "do this", "do that", "why not try this", etc.) or did they tell you to *stop* doing something that you're already doing? When asked to fix or improve a situation (for example, your own health), humans tend to have "additive bias". This is where they usually default to adding or doing something to solve a problem rather than removing or stopping something. We even do this when removing or stopping something is faster, cheaper, simpler, or better.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/33828317/?ref=alphabetguides.com) So it seems that our natural problem-solving tendencies are to add things rather than remove them. So, for health advice and dietary recommendations, "add X to your diet" seems to be more natural than "eliminate Y and restrict Z". ### "Gain-Frame" vs "Loss-Frame" In psychology, the way a piece of advice is worded is called "framing", and it seems to alter how people respond to it. - The **Gain Frame:** Focuses on what you should add or gain (e.g., if you [eat oats](https://www.alphabetguides.com/oats-health-benefits/) for breakfast, you'll gain cholesterol-lowering fibre). - The **Loss Frame:** Focuses on what you must sacrifice or avoid (e.g., if you eat white bread, you'll increase your risk of diabetes). Gain frame messaging appears to be more effective at promoting general "preventative" healthy behaviours. Loss framing works as well, but in much more limited circumstances. Loss framing can be very effective in specific cases, which have high risks and clear and severe consequences. [\[2\]](https://pubmed.ncbi.nlm.nih.gov/21993844/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/9000890/?ref=alphabetguides.com) #### Real world examples where loss framing may work - Telling a patient with severe celiac disease that they must strictly avoid gluten. - Telling a person with an anaphylactic peanut allergy that they must avoid peanuts. - Telling a person with uncontrolled diabetes that they should restrict the amount of refined sugars they eat. Loss framing works here because the consequences are immediate, severe and unambiguous. However, applying emergency-style instructions to everyday health advice for healthy people is a mistake (in our opinion). The negative effects of smoking, eating a [poor diet](https://www.alphabetguides.com/ultra-processed-food-diet/), not brushing your teeth, and being sedentary aren't immediate, obvious or severe. It usually takes years before they start noticeably affecting your health, so people can't link them as easily to one another. So, for broader lifestyle upgrades, we don't see treating everyday eating as a constant medical emergency. Sure, saying "sugar is poison" or "processed foods are as bad as cigarettes" might trick or scare some people into making some temporary changes that may be healthy. But we generally think that the inaccurate alarmist rhetoric psychologically burns people out, and it undermines trust in the long-run. For encouraging dietary changes in the general population, we think gain-framing is the best for long-term adherence. ### It's just about willpower. Or is it? In the scientific community, it is thought that willpower and self-control are not *just* character traits. They are more like a "resource" that you have, and a limited one at that. So, willpower and self-control are not fixed; they can be weakened and depleted with use. Think of it as everyone having a certain amount of "mental energy" in a given time period, and once that is used up, willpower and self-control start to deteriorate.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/10748642/?ref=alphabetguides.com) Trying to avoid certain foods, counting calories and macros, and forcing yourself to say no all day requires continuous mental effort and willpower and leads to decision fatigue. It is exhausting and difficult to maintain long-term. Whereas focusing on eating high-nutrient-density, [low-energy-density](https://www.alphabetguides.com/volumetrics-diet/), and high-fibre foods, which fill your stomach and keep your blood sugar levels low, will make those "bad" foods less appealing. There's less "mental energy" involved. It's also a lot easier to say no to food when you aren't as hungry; it requires less willpower, self-control and mental energy. In total, we think that generally it requires less "mental energy" and effort to direct your focus on the healthy things you *should* be eating rather than the unhealthy things you *shouldn't* be eating. --- ## Reason #2\. Unintended Consequences of Restrictions ### Eating disorders and unhealthy relationships with food A major overlooked danger of "what to avoid" nutritional advice is its potential to create unhealthy relationships with food. The "avoid" messaging relies on strict dietary controls. Foods are divided into "good" or "bad", "clean" or "dirty", "allowed" or "forbidden", "cheat" vs "non-cheat", or "red", "amber" and "green". Rigid dietary control is linked to food anxiety, obsessive thoughts around eating and *possibly* an increased risk of eating disorders. We think that a meal should be there to nourish and be a source of enjoyment, rather than a psychological challenge and anxiety-inducing event.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/10349584/?ref=alphabetguides.com)[\[6\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8745028/?ref=alphabetguides.com) Focusing on what to eat promotes flexible dietary controls ("guard rails"). Encouraging people to eat healthy, nutrient-rich foods, rather than eliminating certain foods, is less psychologically burdensome. When you're focusing on what to eat, no food is "poison", forbidden, or red-zoned. Healthy food is simply prioritised on your plate. More flexible diets are generally more sustainable and associated with better health outcomes and healthier eating habits.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/10349584/?ref=alphabetguides.com) ### A crisis of confidence What-to-avoid recommendations have more downside risk. Particularly if they are difficult to follow. If you're avoiding all ultra-processed food, eating that slice of cake means 100% failure. It is an all-or-nothing approach. So when you fail, it will knock your confidence and potentially cause you to abandon the diet entirely. Or you start on a course of [yo-yo dieting](https://www.alphabetguides.com/yoyo-diet/).[\[7\]](https://pubmed.ncbi.nlm.nih.gov/17963038/?ref=alphabetguides.com) Focusing on "what to eat" has a lower downside risk, as "failure" is a lot less obvious and not as easy to do. You also have an opportunity to correct it later on in the day: if you miss one of your daily servings of legumes at lunch, you can just eat them in the evening or the next day. However, there's no way back if you eat a single cookie on your cookie-free diet — that's the day ruined! Being able to successfully follow a diet generally improves self-confidence (and thus health outcomes). This in turn makes you more likely to follow diets and healthy eating patterns, creating a positive feedback loop. So the easier the healthy diet is to follow (or the less easy it is to fail), the better the long-term health prospects are.[\[8\] ](https://pubmed.ncbi.nlm.nih.gov/17963038/?ref=alphabetguides.com) ### The rebound effect Forbidden fruits taste the sweetest, right? Well, the research supports it. Strict controls around "forbidden foods"(which are usually tasty already) trigger *stronger* cravings. They become more tempting and more difficult to avoid.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/3857016/?ref=alphabetguides.com) Secondly, if or when even a small piece of the "forbidden food" is inevitably eaten, it then goes on to trigger the "what the hell effect". This is where you end up abandoning the diet, because it has been"ruined", which then gives the green light to binge eat the foods you've been trying to avoid. So 200 forbidden food calories can turn into 2,000 in a single day.[\[10\]](https://pubmed.ncbi.nlm.nih.gov/1206453/?ref=alphabetguides.com) ### The health halo When recommendations are too vague and focused on elimination, they are frequently replaced with equally bad or possibly worse alternatives. For example, in the 1990s, when reducing dietary fat was aggressively promoted, the food industry responded with "low-fat" products that replaced the full-fat ones with refined sugars and processed starches. So in some cases you had healthy fats replaced with unhealthy processed ingredients. More recently, people have been on diets that dramatically [cut out carbohydrates](https://www.alphabetguides.com/keto-diet/), replacing whole fruits, legumes and wholegrains with processed foods packed with unhealthy fats, artificial flavourings and sweeteners. Keto bread, anyone? Clear "what to eat" recommendations make this less likely because you are adding healthy whole foods (e.g., oats, legumes, fruit and vegetables) rather than creating a new market for substitute foods. --- ## Reason #3\. The "Crowding Out" Effect Adding healthy food to your diet has two effects. The first one is the obvious one: eating more healthy, nutrient-rich foods brings more nutrients into your body. But secondly (and less obvious), eating healthy foods also "crowds" the unhealthy foods out of your diet. The latter is overlooked. Humans tend to eat a surprisingly consistent "amount" of food each day, irrespective of its calorie or nutrient content. So, when you addhealthy, whole foods that are watery and fibrous, they physically displace the unhealthy, high-calorie, nutrient-deplete foods on your plate.[\[11\]](https://pubmed.ncbi.nlm.nih.gov/16002828/?ref=alphabetguides.com) So you get the double benefits: you add something "healthy" and displace something "unhealthy". There are two reasons why this happens: ### Stomach Stretch [High-volume foods](https://www.alphabetguides.com/volumetrics-diet/) like oats, vegetables and beans contain a lot of water and fibre per gram, and have a low amount of calories per gram of food. So, when they enter your stomach, they take up a lot of room and stretch your stomach. The stretching sends a signal to your brain to tell you that you are full and to stop eating. So you end up eating fewer calories overall.[\[12\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6151490/?ref=alphabetguides.com) ### Gut Peptides As the bulky fibre-rich food reaches your gut, they respond by releasing ["fullness" hormones](https://www.alphabetguides.com/appetite-and-body-weight/) like Glucagon-like Peptide-1 (GLP-1), Gastric Inhibitory Peptide (GIP), cholecystokinin (CCK) and Peptide-YY (PYY). These hormones reduce the amount of food you eat, slow down digestion, keep blood sugar levels low and reduce cravings for unhealthy junk foods.[\[12\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6151490/?ref=alphabetguides.com) --- ## Putting it into Practice _This post is for subscribers only._ ### The Health Benefits of Eating Oats for Breakfast URL: https://www.alphabetguides.com/oats-health-benefits/ Last updated: 2026-09-15T10:23:24.000Z summary - Oats are one of the oldest foods around. They have fed the people of Western nations for centuries. - The cholesterol-lowering effects of oats are quite well known. But they also lower your blood pressure, appetite and blood sugar levels. - Oats are hardy, sustainable and cheap. Replacing your sugary, ultra-processed breakfast with them is our number 1 recommendation. Oats aren't a trend. They're one of the oldest, tried-and-tested breakfast foods around. Modern science backs up what generations of Scots, Irish, and northern Europeans already knew: this is the grain that you should base your morning routine around. Its cholesterol-lowering effects are pretty well known. But it also lowers blood pressure, keeps your appetite and blood sugar levels under control, and has other emerging health benefits for your gut. The case for swapping out the standard Western breakfasts of [ultra-processed](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/) cereals, white toast, and pastries makes the case for porridge even stronger (double benefits). In addition to the health outcomes, adding them to your daily routine also reduces your food bill, the environmental impact, and food security in your region. The sheer staying power of oats as a food makes them one of the simplest upgrades you can make to a [Western diet](https://www.alphabetguides.com/western-diet/). Oats weren't always a staple food. They were originally a wild crop ("wild oats") that was so hardy that it would outcompete wheat. Ancient societies hated it. The Greeks viewed them as a weed only fit for horses. The Romans viewed them as only fit for the Barbarians. And the English viewed it as only fit for the Scots. Throughout history, eating oats was seen as a sign of desperation and generally looked down on. The Greeks, Romans and English loved wheat. But as commercial cultivation of crops spread to Northern Europe, they had problems growing it at scale. Wheat hates damp, cold, acidic soil, but oats don't — they love it. So, by the Middle Ages, oats had become the primary crop that sustained the lower classes across Northern Europe. Nowhere was this more obvious than in the damp, rocky terrain of **Scotland**. Oatmeal became the foundation of the Scottish diet; they developed an entire culinary culture around it. From here, Northern European settlers brought it to North America, where it sustained the people (and their animals) for the next 200 years. In the 1870s, millers started to "steam-roll" the grain, allowing it to cook in just a few minutes (as opposed to a few hours). After this, it was soon commercially sold as a breakfast cereal, and that's how it arrived on our breakfast tables. However, in the late 20th century, that changed. [Convenience foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/), sugary breakfast cereals, and white bread pushed oats from the breakfast table. --- ## Health Benefits of Eating Oats (for Breakfast) "Oats, a grain, which in England is generally given to horses, but in Scotland supports the people." - Samuel Johnson (English writer). James Boswell (Scottish writer) responded to this with "And that's why England has such fine horses, and Scotland has such fine men." Modern research seems to back up what Scotland and the Northern Europeans instinctively knew. Pound-for-pound (and dollar-for-dollar), oats are one of the healthiest foods out there. ### Cardiovascular health benefits of oats The effects of eating oats on your cholesterol levels are probably the most obvious health benefit. Oats contain a lot of a special fibre called "beta-glucan", which forms a thick gel-like substance in your gut. Eating foods that contain beta-glucan meaningfully reduces total cholesterol and the "bad" LDL cholesterol. Regularly eating oats can also lower blood pressure in people who have higher-than-normal blood pressure.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/21631511/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/11978262/?ref=alphabetguides.com) [Heart HealthEvidence-based articles on heart health, covering cardiovascular risk, cholesterol, blood pressure, heart-healthy eating, and lifestyle factors.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-4581e954-87bd-4431-8e35-75e8c13730a2.png)Alphabet Guides![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1659366100463-9e29a63adcc2-ed14c089-2295-4e38-92fa-138a851ae17f.jpeg)](https://www.alphabetguides.com/tag/heart-health/) ### Effects of oats on blood sugar levels Western breakfast staples like sugary cereals, pastries, and white breads with jams, jellies and marmalades are packed with too much sugar that's not good for your health. However, oats are a "low-glycaemic" carbohydrate, meaning they are digested slowly and do not spike your blood sugar and insulin levels as much. They are a smoother and steadier source of energy.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/40326558/?ref=alphabetguides.com) Not only do they keep your blood sugar levels in check at breakfast, but they also carry over to lunch. This is called the "second-meal effect". This means that eating a large portion of oats for breakfast keeps your blood sugar levels *lower* after your lunch (even if it's eaten hours later!). If you are a type 2 diabetic or pre-diabetic with high blood sugar levels, eating oats for breakfast has been shown to lower blood sugar levels throughout the day. ### Are oats good for your gut health? Oats are a rich source of fibre and add "bulk" to your diet. This keeps your digestive system working well and is also good for the healthy bacteria in your gut. These "good" bacteria help strengthen, protect and maintain your gut cells' function. They are also thought to help keep inflammation under control and have cholesterol-lowering effects.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/34486656/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/39137936/?ref=alphabetguides.com) Additionally, most people, including people with gluten sensitivity, can tolerate pure (uncontaminated) oats a lot better than some of the other carbohydrates that are regularly eaten for breakfast. This means less bloating, indigestion, and more consistent bowel movements. ### Effect of eating oats on body weight and body fat Oats are "satiating"; they keep you fuller for longer than your standard Western breakfasts do5. People who eat oats tend to have healthier body weights5, although they are *not* the sole solution to fat loss by themselves. The special fibre contained in oats ("beta-glucan") that forms a gel-like substance in your gut slows digestion, which stimulates the release of [appetite-suppressing](https://www.alphabetguides.com/appetite-and-body-weight/) hormones5. This means less hunger and fewer cravings, so you'll probably eat less food at lunch and throughout the rest of the day. [Fat LossLosing fat and reaching a healthy weight comes down to biology, behaviour, and environment.

Oats are a rare food that seems to help with all four issues, certainly if you swap them for the standard Western breakfast staples. Although eating most types of whole grains provides similar nutritional benefits (and thus have similar health benefits), oats do have some unique features that whole grains don't:[\[5\]](https://pubmed.ncbi.nlm.nih.gov/39137936/?ref=alphabetguides.com) - They have a similar protein content to whole grains but with higher unsaturated fat and more micronutrients (e.g., B vitamins, choline, potassium, phosphorus, magnesium, calcium, iron and manganese). - They are an important source of beta-glucan soluble fibre that underpins a lot of their health benefits. Barley is the only other food that comes close to oats in beta-glucan content. - They contain several unique healthy phytonutrients and some that aren't found in any other foods (e.g., "avenanthramides") There is a reason why they are the number 1 recommendation on our list. --- ## Beyond Nutrition: The Other Benefits of Eating Oats The case for making oats a breakfast essential isn't *just* down to its health benefits. There are a few other reasons why they should be the preferred choice. #### The Environmental Benefits Oats have a (relatively) low environmental impact compared to most other breakfast staples, certainly compared to animal-product breakfast foods (e.g., sausage, bacon and eggs). They also lower the need for fertiliser, pesticides, and herbicides.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/29853680/?ref=alphabetguides.com) #### The Food Security Benefits Oats are tough, hardy, and grow a lot better than many other cereal grains. Resilience matters for food-security: crops that survive bad growing conditions keep prices stable and supply reliable. Their supply chain is robust, stable and centuries old. #### The Cost Benefits Oats are one of the cheapest foods you can buy. They can be bought in bulk and stored for ages in your pantry. A common criticism about healthy eating is the cost. However, eating oats for breakfast will probably **lower* the cost of your shopping. #### The Familiarity Principle Oats aren't just tolerated; they are (or were) genuinely liked. Western nations have been eating them for centuries. They form the basis of many famous dishes, from Haggis and flapjacks to granola and overnight oats. They are baked into Western food culture. #### Versitility They are flexible and can be eaten sweet or savoury, hot or cold, just plain or with added to other ingredients. Tasty dishes can be made in minutes. They are allergen-friendly, naturally gluten-free, and fit in with different religious, cultural and lifestyles (e.g., vegan, vegetarian, kosher and Halal) #### Tried and Tested Few other foods have been as well researched as oats have. Their consistent health benefits have been studied for decades, across the world, in many different types of studies. And maybe just as importantly, they've kept people (and animals) fed for centuries: floods, famines, wars, and empires. --- ![Granola, raspberries and yoghurt filled mason jar.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1490371475955-4cb3bfc72f71.jpeg) ## How to Make Oats an Everyday Staple of Your Diet _This post is for subscribers only._ ### Overtraining: How to Diagnose & Prevent It URL: https://www.alphabetguides.com/overtraining-how-to-diagnose-prevent-it/ Last updated: 2026-09-22T09:02:55.000Z summary - Dips in performance exist on a spectrum ranging from temporary "overreaching" to full, stubborn "overtraining syndrome". - Early diagnosis can prevent it. So track performance markers like your sleep, mood, heart rate, and health status to avoid it. - Overtraining can be prevented by properly planned training, rest, recovery, good nutrition and other lifestyle choices. In Victorian England, prisoners were forced to [exercise](https://www.alphabetguides.com/tag/exercise/) for 6–8 hours a day by treading on wide wooden boards, which spun a wheel. The wheels were (sometimes!) connected to mills that ground grain or pumped water. This is where the word “treadmill” comes from. The purpose of this task was punishment. The goal was to break prisoners' spirits, exhaust them physically, and destroy them mentally. They overtrained them on purpose. ## Defining Overtraining The formal term for overtraining is technically “overtraining syndrome”. It is characterised by a clear and consistent change in the way your body works in response to exercise. Overtraining syndrome *cannot* be attributed to injury or other external factors (other than [exercise](https://www.alphabetguides.com/tag/exercise/)). It’s not easy to diagnose.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/9631215/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/23247672/?ref=alphabetguides.com) Therefore, it is critical to be able to distinguish between the normal fatigue that you experience after you exercise (technically referred to as “overreaching”) and overtraining syndrome. The duration that the fatigue lasts for, the change in your performance, the severity of the other symptoms, the effect that rest has on it, and the presence of other side effects are distinguishing features of overtraining syndrome. It is categorised into three distinct types:[\[3\]](https://pubmed.ncbi.nlm.nih.gov/15571428/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/23016079/?ref=alphabetguides.com) ### #1\. Functional Overreaching This is a short-term increase in the amount of exercise you are doing, followed by a **short** dip in performance. This is then followed by improvements in performance (or strength) and improvement with rest. Functional overreaching is typically expected, normal, and only occurs over a few days. **This is not overtraining**. ### #2 Non-Functional Overreaching Similar to functional overreaching, but performance only returns to baseline without any further improvement in performance after rest. In other words, training is no longer working as intended or as it should be. It can be accompanied by other symptoms, but it is generally cured within a week or two. **This is not overtraining**. ### #3\. Overtraining Syndrome Overtraining syndrome is different from non-functional overreaching, as there is a **persistent** performance decline which lasts months. Performance **doesn’t** return to baseline levels with [rest and recovery](https://www.alphabetguides.com/sleep-for-muscle/). Other physical and mental health issues are usually present alongside the performance decrements. --- ## Physiology of Overtraining: What to Look For Recognising these signs, symptoms, and risk factors early on allows for timely intervention before full-blown overtraining syndrome develops. You are probably looking for at least a handful of these. #### Neurological Dysfunction Symtoms - Weakness and loss of strength or [endurance](https://www.alphabetguides.com/improve-your-vo2max/) - Persistent feelings of fatigue - Slow reaction times - Changes in normal movement patterns - Reduced focus and intensity during training #### Endocrine Dysfunction Symtoms - Decreased [testosterone](https://www.alphabetguides.com/testosterone-blueprint/) - Increased [cortisol](https://www.alphabetguides.com/what-is-cortisol/) - Amenorrhoea - Impaired "fight-or-flight" response #### Immune Suppression Symtoms - More frequent illnesses (particularly upper respiratory tract infections like colds, coughs, flus) - Longer recovery from injury - Elevated [inflammatory markers](https://www.alphabetguides.com/anti-inflammatory-diet/) - Persistent pain, stiffness, or soreness in muscles or joints. #### Autonomic Nervous System Dysregulation Symtoms - Poor [sleep](https://www.alphabetguides.com/tag/sleep/) - A change in resting heart rate (higher or lower than normal) - Inability to increase heart rate during exercise - High blood pressure - Headaches, stomach aches, and stomach problems - Tiredness, [loss of appetite](https://www.alphabetguides.com/appetite-and-body-weight/) or unintended weight loss or weight gain. #### Psychological Symtoms - Irritability and mood swings. - Low motivation or enjoyment for training - Increased anxiety and/or depression - Poor concentration and [brain fog](https://www.alphabetguides.com/tag/brain-health/). #### Performance Changes - Inconsistent performance, or performance plateauing or worsening despite training. - Inability to give full effort to training or to complete the expected workout targets. - Longer (than usual) recovery times. - Poor response to stimulants like caffeine. #### Risk Factors Present - Excessive training volume or intensity without adequate rest and recovery. - Monotonous programming, poor nutrition, poor sleep. - Outside stress from work, school or personal life. - Previous illness, exposure to environmental extremes (e.g., heat or altitude) or increased travel demands. ## Preventing Overtraining: Programming and Lifestyle Solutions The only nonmedical, widely recommended treatment for overtraining syndrome is **rest**. It's debatable whether this means complete rest (i.e., no exercise at all) or relative rest (i.e., more rest than normal). But more rest is the prescription. However, preventing overtraining is much, much better (and easier) than trying to cure it. Here are some tips:[\[5\]](https://pubmed.ncbi.nlm.nih.gov/29345524/?ref=alphabetguides.com) _This post is for subscribers only._ ### Fuel for Muscle Growth: Calories, Protein & Macros URL: https://www.alphabetguides.com/muscle-fuel/ Last updated: 2026-09-06T08:00:01.000Z summary - Muscle can be built while you're in a calorie deficit, but a moderate surplus offers the best environment for maximising growth. - All three macronutrients are important. Proteins provide the building blocks for muscle, while carbohydrates and fat provide the fuel. - However, the quality of your macros matters. Whole foods and animal proteins are generally higher-quality, but there are other options. The kilocalorie (kcal for short) is the unit of energy for food. Understanding the relationship between the amount of energy you eat (your "energy intake") and the amount of muscle you grow is a little more complicated than the "eat big, get big" mantra. Once you've got the calories roughly right, it's balancing the [protein](https://www.alphabetguides.com/tag/protein/), carbs, and fat, and then the quality of that protein that actually determines how much of that energy turns into muscle. ## Defining energy balance Energy balance is the fundamental equation that determines [body mass](https://www.alphabetguides.com/tag/fat-loss/). It's calculated by subtracting energy expenditure from energy intake. When intake exceeds expenditure, that's an energy surplus. When expenditure exceeds intake, that's an energy deficit. When the two are approximately equal, that's energy balance. This simple equation gets more complicated once you factor in that both sides of the equation change day to day, are nearly impossible to measure accurately, and are influenced by other processes (including muscle growth itself). Energy expenditure comes in *four* forms: 1. Planned [exercise](https://www.alphabetguides.com/tag/exercise/) 2. Any other movement that isn't planned exercise 3. Digesting food 4. Maintaining basic bodily functions. Your heart, lungs, stomach, and intestinal muscles don't contract themselves (they need energy too). You can measure energy expenditure with expensive lab equipment. But in practice, it's normally just estimated. The simplest way is based on body weight, though more complex equations exist. Measuring energy intake has its own problems. Errors in judging portion size, along with variations in food composition, nutritional content, and cooking method, all affect how accurate your intake estimate really is. Even with kitchen scales, diligent records, and a good tracking app, measuring intake precisely remains genuinely difficult.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/21558571/?ref=alphabetguides.com) Fortunately, over the long run, your hypothalamus (and several other bodily systems) keeps a fairly accurate running tally of how many calories you're eating and burning, through a process known as "biofeedback" or [appetite regulation](https://www.alphabetguides.com/appetite-and-body-weight/). A measuring tape and a reliable set of bathroom scales are usually all you need to [track the result](https://www.alphabetguides.com/beyond-the-scale/) of what you eat over time. ## Energy Surplus: Necessity or Luxury for Muscle Growth? [Resistance training](https://www.alphabetguides.com/resistance-training-beginners/) combined with higher energy intakes generally leads to greater muscle hypertrophy than lower calorie intakes. This doesn't mean gaining muscle while eating fewer calories is impossible — just more difficult.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/31482093/?ref=alphabetguides.com) It's also worth noting that more calories doesn't always mean more muscle. The exact amount of energy needed to maximise growth can't be estimated with an equation, as it depends on individual needs and your macronutrient intake Running a small to moderate surplus (roughly 10–20% above your estimated maintenance) is a sensible place to start.

But you'll likely gain less muscle, and gain it less easily, than if you were in a surplus or at maintenance levels. This becomes especially true with severe calorie deficits (over 500 calories a day), where gaining muscle becomes very difficult, and simply maintaining muscle mass (or minimising its loss) becomes the more realistic goal. Protein intake is the key determining factor. In an energy deficit, higher protein intakes are required (above 1.4 g/kg/day) because maintaining muscle becomes more metabolically "expensive": your body will break muscle down for energy to keep vital organs running (a process known as muscle protein breakdown).[\[3\]](https://pubmed.ncbi.nlm.nih.gov/24092765/?ref=alphabetguides.com) --- ## The Three Macronutrients Protein, carbohydrate, and fat each serve a distinct role in muscle growth, but they're rarely consumed in isolation. Most meals, and even most individual foods, contain some combination of all three. But how these macronutrients interact creates a unique environment within your muscle that either supports or hinders growth. ### Protein: the muscle builder Protein acts as both a building block and a signalling molecule for muscle growth; it's the single most important nutritional factor for maximising it. There's no total agreement on the ideal amount, but most experts think that 0.8 grams per kg body mass a day is the bare minimum, with little added benefit from eating beyond 2.4 grams per kg body mass a day, regardless of how much you're training.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/28698222/?ref=alphabetguides.com) The practical "sweet spot" for most people sits around 1.4–2.0 grams per kg body mass a day — trending toward the higher end of that range, or beyond it, when you're in an [energy deficit](https://www.alphabetguides.com/nutrition-and-body-recomposition/). Split across three main meals and two snacks, this works out to roughly 0.3–0.4 g per kg per meal and 0.15–0.2 g per kg per snack — or, more simply, aim for at least 20 g of high-quality protein every time you eat. ### Protein quality: why source matters Protein "quality" is arguably more important than hitting a raw gram target, and depends on two factors: digestibility (how readily your body actually absorbs it) and how completely it supplies each of the nine [essential amino acids](https://www.alphabetguides.com/amino-acids-muscle/) (EAA). Several scoring systems exist to measure this, the most common being the Digestible Indispensable Amino Acid Score (DIAAS). Sources are scored from 0 (lowest quality) upward, with "excellent" proteins scoring over 1.0 and "low" quality proteins scoring under 0.75\. A score of 1.0 means the protein supplies 100% of your digestible EAA needs; a score of 0.7 means only 70% — so you'd need to eat more of it to close the gap.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/25757896/?ref=alphabetguides.com) Simply eating more of a low-quality protein isn't always practical, but there are better strategies available. As a rule of thumb, animal sources (i.e., meat, fish, dairy, eggs) are "complete" proteins, containing all nine digestible EAAs in adequate amounts. [Plant proteins](https://www.alphabetguides.com/plant-based-protein/) are often "incomplete," typically falling short in one of two amino acids: cereals (wheat, rice, maize) tend to be low in lysine, while legumes (beans, pulses, soy) tend to be low in methionine. Combining the two (e.g., rice and lentils, beans on toast, hummus and pita) creates a complete amino acid profile through a strategy known as protein "complementation".[\[6\]](https://pubmed.ncbi.nlm.nih.gov/26224750/?ref=alphabetguides.com) Processing is a second lever on protein quality. Despite its reputation, processing isn't inherently bad. There's a real difference between minimal processing and "[ultra-processing](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/)" Soaking, drying, cooking, and fermenting are all technically processing, done for millennia, and some of these methods actually improve nutritional profile, palatability, and protein quality. ### Fast and slow proteins Digestion speed matters too. [Different proteins](https://www.alphabetguides.com/plant-based-diet-meal-plan/) release amino acids into your bloodstream at different rates: "fast" versus "slow" digesting. Whey and casein, the two principal dairy proteins (together accounting for over half of global protein supplement sales), are a well-known example: whey digests quickly, spiking blood EAA levels and stimulating muscle growth rapidly, while casein forms a gel-like substance in the stomach and releases more slowly. Both are high-quality proteins delivering similar total EAA, just at different speeds.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/28847314/?ref=alphabetguides.com) At higher doses (over 20 g), this difference in speed doesn't affect muscle growth much. But at lower doses, faster proteins tend to stimulate growth more efficiently, while slower proteins are better at maintaining protein balance and delaying hunger across longer gaps between meals (over six hours, like overnight). Blending the two is a smart way to capture both benefits; this is how they occur naturally anyway. Dairy products are the best source of these proteins if you're going for whole foods.

Learn how to eat enough of them and what type of protein you need to eat.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-e4ecc7b8-a151-4550-828e-cb04e1142365.png)Alphabet Guides![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1579722822163-0504256cf3a7-766483f4-25d2-4c68-8d59-497e1c93fd78.jpeg)](https://www.alphabetguides.com/tag/protein/) ### Carbohydrates: fuelling performance and recovery Carbohydrates supply the energy needed to fuel your training sessions and support recovery. They also "spare" muscle from being broken down for energy, and reduce muscle protein breakdown. After you eat carbohydrate it's stored in muscle as glycogen. Enough for roughly an hour or so of moderate-to-hard exercise. So, under-eating carbohydrates will likely impair your ability to train at full capacity and, in turn, impair muscle growth (indirectly). Carbohydrates also stimulate insulin release, a [hormone](https://www.alphabetguides.com/tag/hormones/) that supports muscle growth, which is one reason carbs are so often advised to be eaten alongside protein.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/21660838/?ref=alphabetguides.com) At a minimum, aim for around 20 g of carbohydrate alongside protein at each meal or snack. This is usually enough to stimulate insulin and cover basic energy needs. Broader recommendations run considerably higher, from 3–5 grams per kg body mass per day up to 6–10 g/kg/day for those doing a lot of exercise. The top end of that range is generally reserved for endurance athletes. ### Fats: The overlooked supporter of muscle growth Dietary fat plays a supporting role in muscle growth that's often overlooked. Beyond providing energy, fat helps [male hormones](https://www.alphabetguides.com/the-testosterone-diet/), maintains the structure of your cells, and helps with the absorption of certain vitamins. [Testosterone](https://www.alphabetguides.com/testosterone-and-muscle-growth/) is important for muscle maintenance and growth in both men and women. It requires certain fats (including cholesterol and saturated fat) to be produced, and diets with adequate fat intake tend to sustain healthier testosterone levels.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/24864135/?ref=alphabetguides.com) As a general guide, aim for 15–30% of daily energy intake from fat, prioritising high-quality sources just as you would with protein. Monounsaturated and polyunsaturated fats are a good foundation, and there's solid evidence that [omega-3 fatty acids](https://www.alphabetguides.com/superfood-oily-fish/) support muscle growth (particularly in older adults). Saturated fat is fine in modest amounts for most people (under 10%of energy intake, roughly 20g a day) when it comes from natural, minimally processed sources; trans fats should be avoided altogether. Too much fat (both dietary and body fat) can impair muscle growth. So keeping an eye on [body weight](https://www.alphabetguides.com/3-underrated-ways-to-lose-fat/), waistline, and total energy intake alongside food quality is worth doing.

URL: https://www.alphabetguides.com/doms/ Last updated: 2026-09-24T10:38:25.000Z Key takeaways - DOMS is muscle soreness that occurs 12–48 hours after intense or unfamiliar exercise, caused by microtears in your muscle fibres. - It triggers inflammation and repair processes, particularly after you've done a lot of eccentric (lengthening) contractions. - DOMS isn't required for growth, but the inflammatory response aids repair. Activity recovery, nutrition and rest can help you manage it. If you’ve woken up a day or two after a tough workout feeling a dull, aching soreness in your [muscles](https://www.alphabetguides.com/tag/muscle/), you’ve experienced what is commonly known as Delayed Onset Muscle Soreness (DOMS for short). For many people who are trying to grow their muscles, DOMS can be an expected part of training. But what exactly is happening in your muscles? Is it good or bad? Can you fix DOMS, or should you leave it be? We'll try to answer some of these questions in this article. ## What is DOMS? DOMS typically occurs 12–48 hours after unfamiliar and "intense" physical activity. Particularly, after exercises involving “eccentric” muscle contractions, where the muscle lengthens under force (e.g., walking downstairs, lowering the weight during a bicep curl).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/11731568/?ref=alphabetguides.com) This soreness differs from "acute" exercise pain. It doesn't happen straightaway (hence the D for "delayed" in DOMS). It's distinct from the sharp, intense pain of getting injured during training. DOMS is different, as it generally gets *worse* long after you’ve left the gym. DOMS is caused by “microtrauma” and biochemical imbalances that are inflicted on the muscle while you're [exercising](https://www.alphabetguides.com/tag/exercise/). This damage disrupts the structure of the [muscle cells](https://www.alphabetguides.com/muscle-fibre-types/) and the connective tissue that surrounds them.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/28035017/?ref=alphabetguides.com) The initial mechanical "strain" to your muscle is caused by lifting and lowering the weights, which triggers inflammation and the release of molecules that stimulate pain signals to your brain. However, this inflammatory response is thought to also play a central role in stimulating muscle growth and repair. Your muscles respond to microtears by activating your “satellite cells”. These special cells then go on to accelerate the repair and growth process in your muscle. The connection between muscle damage, inflammation, and regeneration underscores why DOMS is sometimes considered a marker of an [effective workout](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/), meaning that your muscles are adapting. ![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/08/doms-1.jpg) However, it's important to clarify that experiencing DOMS is *not* required for muscle growth. No pain *doesn’t* mean no gain. No DOMS *doesn't* mean no growth. You can stimulate growth with or without DOMS, as the principal driver of growth is mechanical tension (and maybe a bit of metabolic stress), not pain.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/21270317/?ref=alphabetguides.com) The severity and duration of DOMS can vary between different people, different muscles, and different workouts. There are several factors that influence it.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/12617692/?ref=alphabetguides.com)[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4983298/?ref=alphabetguides.com) - Novel types of exercise, greater loads, intensities, and volumes typically lead to more muscle soreness. - “Eccentric” muscle contractions generally cause more severe DOMS than “concentric” (muscle shortening) contractions - Training age: Experienced lifters tend to experience less severe DOMS as their muscles have adapted to training. This is known as the “repeated bout effect”. - Genetics & Age: Older adults tend to recover more slowly, and there are some genes that can either speed up or slow down recovery. --- ## How To Tell the Difference Between Injury and DOMS? #### Signs that it's an ****injury** **!** - Localised to a single region - Immediate pain and soreness - Last weeks - "Sharp" pain #### Signs that it's DOMS - Localised to the working muscles - Delayed onset of soreness (doesn't happen straightaway) - Lasts a few days, then starts to get better - "Stiff" and "achy" pain --- ## How to Manage DOMS This is a common problem for anyone who is serious about training hard and training regularly. While soreness is a natural part of the adaptation process, excessive soreness can hinder performance and motivation.

Low-Fat Diets & Fat Loss URL: https://www.alphabetguides.com/eating-fat/ Last updated: 2026-09-03T07:44:13.000Z summary - Low-fat diets work by lowering the "calorie-density" of your diet, which means you're eating more food for fewer calories. - But other types of diets are just as effective if your total calorie intake is the same (e.g., low-carbohydrate, intermittent fasting). - Not all low-fat diets are always healthy. The better ones encourage intake of other nutrients as well (e.g., protein, fibre, and some healthy fats). Eating fat makes you fat! Or so we thought. The low-fat diet has dominated weight loss diet advice for several decades. It remains the cornerstone of most [weight loss programmes](https://www.alphabetguides.com/tag/fat-loss/) and is still a proven way to lose fat and maintain a healthy bodyweight. But, with the expanding waistlines over the past few decades, there's been a lot of research on alternative ways to lose body fat (e.g., keto, [fasting](https://www.alphabetguides.com/tag/fasting/), protein, food composition, etc.). So, does the low-fat diet still stand up against the new alternatives? ## What are Low-Fat Diets? Low-fat diets typically restrict fat intake to less than \~20-30% of total calories. That's nothing special, right, and doesn’t sound particularly low! But it’s actually what most health institutions have been recommending for ages; it is lower than the current dietary fat intake in the [Western diet](https://www.alphabetguides.com/western-diet/) (typically 29-46% of calories).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/26877707/?ref=alphabetguides.com) The theory behind the low-fat diet is that to create an energy deficit, you are best reducing the most energy-dense foods first. So you're basically picking the low-hanging fruit. Dietary fat provides around 9 calories per gram, whereas protein and carbohydrate contain around 4calories per gram. So if you limit fat intake, you'll naturally consume fewer total calories and keep hunger at bay for longer.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/12133213/?ref=alphabetguides.com) This is done by eating [larger volumes](https://www.alphabetguides.com/volumetrics-diet/) of lower-calorie foods. However, this also requires distinguishing between *naturally* low-fat whole foods and processed “low-fat” products, which often compensate for less fat by adding sugar and artificial flavourings and sweeteners. [Low-Fat Diets: A ReviewOnce the dominant dietary advice for weight loss and heart health, but what does the current evidence say?![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-e2d37631-641a-4f5a-8fea-ad87c5144ae6.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1606858274001-dd10efc5ce7d-29916515-3886-4ac0-a952-41977b491b98.jpeg)](https://www.alphabetguides.com/low-fat-diet/) **Less fat doesn’t always mean more fat loss or more healthy.** "Ultra-low-fat [diets](https://www.alphabetguides.com/ornish-diet/)" (i.e., those under 10% calories from fat) have also been used for fat loss purposes. However, a dietary fat intake of around 20-30% total calories (spread throughout the day) is considered more beneficial both for fat loss and general health. After all, a certain amount of dietary fat is needed to provide an adequate supply of essential fatty acids, satiety, and the absorption of fat-soluble vitamins, while also maintaining the calorie-reduction benefits at the same time. It's also advised that whole foods intake, [protein](https://www.alphabetguides.com/tag/protein/) and fibre intake should be increased while lowering-fat intakes. Replacing healthy fats with more sugar is unlikely to promote fat loss (or health) in the long run. ## Calorie Density and Fat Loss Low-fat diets do lead to significant weight loss and fat loss. Meaningful weight loss has been reported in a few months. This is achieved by creating an energy deficit. We know this because other diets (e.g., low-carb and [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/)) led to a similar amount of weight loss when protein and total calorie intake was about the same. But a unique advantage of low-fat foods and low-fat diets is that they are less “calorie-dense” (i.e., kcal per gram of food).[\[3\]](https://pubmed.ncbi.nlm.nih.gov/11126204/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/18635428/?ref=alphabetguides.com) Foods with low calorie density also tend to be low in fat (e.g., [fruits, vegetables](https://www.alphabetguides.com/tag/plant-based/), grains, legumes, and lean proteins). Whereas foods high in fat (e.g., nuts, oils, fatty meats, spreads) contain 2–4 times the amount of calories per gram. This dramatic difference allows you to eat larger, but just as satisfying portions of food, whilst consuming fewer calories.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/19303887/?ref=alphabetguides.com) How? Well, the stomach's “stretch receptors” respond to food "volume" or mass, not calories. These receptors trigger the “I’m full” satiety signals that stop you eating. So if you can trigger this response by eating fewer calories, you end up consuming fewer calories. 💡 Large salads, vegetable soups or broths, and fruits give you some of the best volume per calorie ratios. --- ## Low Fat vs. Low Carb: What Wins? - **Low-fat diet wins**: More flexible, easier to follow, better general nutrition, better for general health, better for athletes and people who are active. - **Low-carb diet wins:** Better satiety and quicker weight loss ([but not necessarily fat loss](https://www.alphabetguides.com/beyond-the-scale/)). - **Draw:** Similar reported cravings and hunger, similar long-term weight loss and fat loss, similar amount of evidence supporting the effectiveness of both diets. **Winner = Low-fat beats low carb 5:2** --- ## "Healthy" Low-Fat Diets General advice when starting to reduce dietary fat intake is to: 1. *Gradually* reduce “added fats” in your diet (i.e., cooking oils, butter, lard, tallow, etc.). 2. Structure meals around lean proteins, vegetables, high-fibre and starchy carbohydrates. 3. Then add small amounts of healthy fats for cooking or flavour (i.e., 5–10 g per meal from nuts, seeds, avocados, [olive oil](https://www.alphabetguides.com/superfood-olive-oil/) or fatty fish). 4. Use cooking methods like baking, grilling, air-frying, or poaching that don’t need added fats. 5. Herbs, spices, and acids (e.g., citrus juices or vinegars) can improve flavour without adding more fat. 6. Keep an eye on food labels or packaged foods; they may have more fat than you think. 7. Track your fat intake for the first few weeks to develop portion awareness whilst you change to meals and whole foods that are naturally lower in fat. 8. Monitor your body weight, hunger, energy levels, digestion and meal satisfaction. Not everyone responds well to lower-fat intakes. You can experiment with different amounts of fat (e.g., 15-20% vs. 20-25% vs 25-30% total calories) and see which you respond to best. Red flags include persistent hunger, low energy, poor exercise capacity, training performance or recovery. Successful long-term low-fat diets usually require finding the "sweet spot" where you achieve meaningful fat loss while maintaining adequate [nutrition](https://www.alphabetguides.com/tag/nutrition/), meal satisfaction, and compatibility with your lifestyle. Flexibility can prevent the all-or-nothing thinking that often undermines diets. ## Bottom Line Low-fat diets and low-fat foods are still scientifically supported for fat loss, although there are *now* many other options available.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/26527511/?ref=alphabetguides.com) Low-fat diets work by reducing the calorie density of meals and total calorie intake. And they can be effective for people who like (and can tolerate) eating a higher amount of carbohydrate. But reduced fat intake might not be suitable for everyone. Not all low-fat diets are equally healthy or equally effective for fat loss. To tip the chances in your favour, it is crucial to emphasise the intake of nutrient-dense whole foods rather than processed sugary low-fat food substitutes. Maintaining adequate (or slightly higher) protein intake, fibre intake and careful selection of healthy dietary fats is essential for long-term adherence and health.

[Nature](https://www.alphabetguides.com/mediterranean-culture/#7-eat-and-live-with-the-seasons) --- ## #1\. Healthy Mediterranean Traditions ****Summary:** Mediterranean traditions emerged from geographical, economic, religious and cultural practices: through necessity, not design. Slow, social cooking and eating, frugality, and resourcefulness have also contributed to the health-protective effects of their diet and lifestyle. ### Geography The hot, dry summers and mild, wet winters of the Mediterranean basin favour olive production, but make it challenging to produce grain and livestock. Limited rainfall made vegetables precious, which encouraged preservation methods when there was a glut: sun-drying tomatoes, brining olives, fermenting vegetables, concentrating flavours and nutrients while extending shelf-life. Proximity to the sea made fish accessible, while mountainous terrain limited cattle grazing, naturally lowering their intake of red meat. It’s the geography of the Mediterranean that shaped what they eat. The Mediterranean diet wasn’t initially designed for health; it was done for survival. Before [industrialisation](https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/), diets evolved to supply nutrients sustainably. This shows that tradition, rituals and modern nutrition science have more in common than you think.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/9420448/?ref=alphabetguides.com) ### Religion In addition to geography, religious traditions have influenced the Mediterranean lifestyle.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/9420448/?ref=alphabetguides.com) - Christian and Islamic fasting practices unintentionally reduced saturated fat, portion size, and meat intake. - Judeo-Christian weekend practices encouraged slow-cooked foods, cold vegetables and salad dishes that were prepared beforehand. - Weekend meals are leisurely, family gatherings, where food is eaten slowly while talking to each other. These are all things that modern science now recognises as beneficial to health — a mere four thousand years later. ### Economy Frugality and resourcefulness are also common traditions in Mediterranean cuisine: maximising nutrition from humble ingredients. Stale leftover bread becomes a panzanella salad. Vegetable scraps and legume cooking liquid are the base for a soup or stew. Less affordable meats or fish are an accompaniment to [plants](https://www.alphabetguides.com/tag/plant-based/), not the centrepiece. Legumes, whole grains, vegetables, and fruits dominate the plate, not for their nutritional content but because they're affordable. ### Family Historically, the evolution of food, cooking and dietary practices in most regions was passed down through generations. Grandmothers taught grandchildren to make bread, preserve vegetables, and forage wild greens. They were taught to understand the seasons, how to pick the best ingredients, prepare the food properly, flavour it properly, and serve the appropriate portions. Over generations, this creates intuitive, hardwired, healthy eating practices; no calorie counting, no nutritional profiling or calculations required. Children who help prepare their food go on to develop healthier diets and positive relationships with food. You don’t have to return to pre-industrial life to replicate traditional Mediterranean practices. Why not just honour traditions and the collective trial and error of generations, but apply it where it fits. Take what works, what is backed by science, and adapt it to your lifestyle. Cook simple dishes at home with whole, unprocessed ingredients. Eat seasonally. Minimise food waste. Make meals social occasions. Teach your children how to prepare, cook and serve meals. This will help create sustainable, healthy eating that is culturally connected, not concocted in a lab or by a marketing team.[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC11855907/?ref=alphabetguides.com) --- ## #2\. Mediterranean Physical Activities ****Summary:** Regular physical activity improves health and longevity. Movement is woven into the traditional Mediterranean lifestyle: walking, dancing, gardening and other activities whilst socialising at the same time. Physical activity has always been part of the Mediterranean culture, though not in the structured, formal “exercise”: no Zumba, spin or CrossFit classes here. Rather, traditional Mediterranean activities involved walking as their primary mode of transport; manual labour in agriculture or fishing, dancing at social gatherings, and active daily living (usually outdoors). Movement is naturally woven throughout the day. This, combined with the [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/), is the main driver of their exceptional health and longevity outcomes. People who follow the Mediterranean diet *and* are physically active have a reduced chance of death compared to either diet or exercise alone. The combination of physical activity and the Mediterranean diet also prevents [cardiovascular disease](https://www.alphabetguides.com/tag/heart-health/), type 2 diabetes, and some cancers better than just being on the Mediterranean diet or being physically active.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/28964855/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/34462020/?ref=alphabetguides.com)[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC7910909/?ref=alphabetguides.com) Physical activity acts on a lot of the same parts of the body, similar to the way that the Mediterranean diet does. Regular exercise and physical activity improve your ability to control your blood sugar (and fat) levels. This is complemented by the Mediterranean diet's low-GI carbohydrates, unprocessed foods, and healthy fats.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/30366431/?ref=alphabetguides.com) Those who are physically active tend to have lower inflammation and oxidative stress, which is (again) complemented by the Mediterranean diet’s high intake of [anti-inflammatory](https://www.alphabetguides.com/anti-inflammatory-diet/) and antioxidant-rich foods. Being physically active improves cardiovascular health, which is complemented (again) by the Mediterranean diet's intake of omega-3s (from oily fish), polyphenols and other nutrients that support healthy blood vessels. Moving like a Mediterranean doesn't require marathon running, gym memberships or expensive classes. The traditional Mediterranean approach to movement relies on low- to moderate-intensity activities sustained throughout the day and throughout life: [brisk walking](https://www.alphabetguides.com/why-walking-beats-running/), cycling, swimming, dancing, gardening, cooking and active recreation. Just as important are the social aspects of physical activity. Mediterranean cultures traditionally socialise whilst being physically active. So, walking with family and friends, dancing at community events, and playing active games with your children. This social element likely contributes to better adherence than exercising by yourself, and it probably has some [mental health](https://www.alphabetguides.com/tag/brain-health/) benefits as well. Mediterranean-style exercise and physical activity should be joyful, not laborious. Find activities that you genuinely enjoy and can share with others. This will increase the likelihood of your maintaining an active lifestyle throughout your life.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/29590337/?ref=alphabetguides.com) [ExerciseEvidence-based exercise guides on strength, endurance and conditioning — practical programs and principles to build fitness safely.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-63408e38-00ba-4124-8909-3db815c67cca.png)Alphabet Guides![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1776977519844-634b564d4a9a-4b46ef33-1974-452e-bb16-c53d9c9c4ae8.jpeg)](https://www.alphabetguides.com/tag/exercise/) --- ## #3\. Mediterranean Xeniality ****Summary:** Social relationships can be strengthened over meals. Three leisurely meals a week, lasting at least 30 minutes, is probably a good starting point. Being welcoming to others can support community health, nutrition, and mental and physical health. There's little downside. “Xeniality” means to be hospitable and generous to guests. It comes from the Greek word “xenos” meaning “guest” and also “host”. The word captures an essential but underappreciated aspect of the Mediterranean lifestyle: socialising. Traditional Mediterranean cultures view meals as communal experiences, opportunities for connection and happiness that are as good for your health and longevity as the foods that are eaten. Having strong social relationships reduces the risk of death by half. That is similar to quitting smoking, and is healthier than being physically active and having a normal body weight.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/20668659/?ref=alphabetguides.com) Shared meals strengthen social bonds while at the same time supporting healthy eating behaviours. People who regularly eat with others tend to eat more vegetables and fruits, eat more varied diets, and consume fewer [ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/) compared to those who eat alone. The social "context" of eating changes it from a mere "fuel stop" into an event that naturally encourages healthier food choices. ### Health benefits of being xenial Mediterraneans have a tradition of leisurely, multi-course meals shared around the table (e.g., mezze, apéritifs, appetisers, tapas, or antipasto). This naturally slows how quickly you eat. It spreads calorie intake over a longer period of time. Slower eating, taking at least 20 minutes per meal, allows [“fullness” hormones](https://www.alphabetguides.com/appetite-and-body-weight/) to take effect, reducing overconsumption but without restriction or willpower.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/26100137/?ref=alphabetguides.com) Social dining also naturally slows the pace of eating: conversations, sharing dishes, and the cultural tradition of hanging around the kitchen and dining table. Greek and Italian meals traditionally last hours, with multiple small courses interspersed with conversation. It's a pattern that promotes "mindful" eating practices and normal portion sizes without any conscious effort. Sharing meals with loved ones can also [reduce stress](https://www.alphabetguides.com/ways-to-decrease-cortisol/) (depending on the company!). Regular family meals have been shown to improve the physical and mental health of all attendees, irrespective of what they’re eating.[\[10\]](https://pubmed.ncbi.nlm.nih.gov/15289253/?ref=alphabetguides.com)[\[11\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4325878/?ref=alphabetguides.com)[\[12\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6309329/?ref=alphabetguides.com) ### How to practice xeniality effectively This principle can extend beyond immediate family to broader community health. Welcoming neighbours, acquaintances, and even strangers can protect others from isolation and loneliness. Social networks and community engagement are now viewed as key contributors to health. Busy schedules, the dispersal of families, distracting screens, and the popularity of individual food culture (i.e., "I’ll eat what I want, as much as I want, when I want") all undermined the communal ritual of eating together. However, even modest amounts of social eating (just three times a week) have been shown to improve nutrition, mental health and lower rates of obesity than those who eat alone.[\[11\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4325878/?ref=alphabetguides.com)[\[12\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6309329/?ref=alphabetguides.com) Designate specific meals every week as screen-free, sit-down occasions with other people. Potlucks, supper clubs, and neighbourhood meals are good examples. Even if you are alone or far away from loved ones, video meals are an option. Make meals longer by talking and splitting food over multiple courses. Change meals from lonely fuel stops and into pleasurable, social experiences. ![Outdoor dining table overlooking a serene sea and distant mountains.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1780914117972-7997f4459523.jpeg) --- ## #4\. Moderation is Everything ****Summary:** The Mediterranean diet tends to be easier to follow than other diets. They prioritise moderation and flexibility, food quality, pleasure, and enjoyment while still having better health outcomes than most other diets. Traditional Mediterranean eating naturally emphasises moderation over [elimination](https://www.alphabetguides.com/elimination-diet/). Red meat is enjoyed occasionally rather than forbidden entirely. Wine accompanies meals in modest amounts. Sweets and desserts aren’t “cheats” but appear at celebrations without guilt. This flexible approach contrasts sharply with the usual restrictive diets that categorise foods as “good” or “bad”, which can create psychological stress and [yo-yo dieting](https://www.alphabetguides.com/yoyo-diet/). Rigid, restrictive diets generally have poorer long-term adherence and health outcomes. They also tend to lead to weight gain (and regain), and disordered eating patterns, while flexible diets are more sustainable in the long run.[\[13\]](https://pubmed.ncbi.nlm.nih.gov/36296998/?ref=alphabetguides.com) Irrespective of their content, the Mediterranean diet is much easier to follow than [low-fat](https://www.alphabetguides.com/low-fat-diet/), low-carb or other restrictive diets. This seems to translate to better long-term health outcomes, especially for combating chronic diseases that take years or decades to become a problem (e.g., cardiovascular disease, [cognitive diseases](https://www.alphabetguides.com/tag/brain-health/), diabetes).[\[14\]](https://pubmed.ncbi.nlm.nih.gov/34423871/?ref=alphabetguides.com) The concept of moderation extends beyond single foods or food groups to full eating patterns and portion sizes. Mediterranean meals emphasise an abundance of plant foods: vegetables, fruits, legumes, and whole grains, while animal proteins serve as accompaniments rather than the centrepiece. This approach naturally creates [nutrient-dense meals with fewer calories](https://www.alphabetguides.com/volumetrics-diet/). Mediterraneans also don't worry that individual meals will vary in their composition. One meal might be vegetable-heavy, another might include more [protein or meat](https://www.alphabetguides.com/mediterranean-meat-dairy/), while a celebration might feature richer foods. This flexibility eliminates the perfectionism that derails many attempts to change dietary habits. In most cases, overall consistency across weeks and months matters far more than individual food choices or the occasional indulgence. The Mediterranean diet emphasises general principles and guidelines, rather than yes/no rules, which allows it to accommodate personal preferences, cultural variations, and real-life circumstances. Psychological benefits of moderation positively impact both mental and physical health. The absence of forbidden foods reduces food-related [anxiety](https://www.alphabetguides.com/exercise-and-anxiety/) and the appeal of “off-limits” foods. People who follow flexible, moderate diets report higher diet satisfaction, better quality of life, and lower rates of binge-eating, relapse, and yo-yo dieting compared to those on restrictive plans. A positive relationship with food, viewing eating as nourishing and pleasurable rather than a regime, supports better adherence and [lower stress](https://www.alphabetguides.com/what-is-cortisol/), which are an integral part of the Mediterranean lifestyle and general health. - Shift from the common all-or-nothing thinking to a more balanced approach. - Focus on what you're adding: more vegetables, legumes, whole grains, olive oil, rather than what you're eliminating. - Enjoy a wide variety of foods without labelling any as forbidden. - Pay attention to feelings of hunger and fullness rather than rigid portion rules. - Allow flexibility for social occasions, travel, and personal circumstances. Consistency beats perfection. - Try to get most meals following the Mediterranean diet principles, but accept that perfection is neither necessary nor sustainable. --- ## #5\. Taste and Flavour: Healthy Doesn't Mean Bland _This post is for subscribers only._ ### Do These Genes Make Me Look Fat? The Genetics of Obesity URL: https://www.alphabetguides.com/fat-genes/ Last updated: 2026-09-22T09:41:47.000Z key takeaways - Your genes influence appetite, metabolism, fat storage and exercise capacity, but they can also interact with lifestyle and environment. - Having “fat genes” does increase your susceptibility to obesity, but it doesn't guarantee it or prevent you from losing fat. - Your environment and lifestyle can influence how fat genes affect your body fat levels. You should work with your genetic strengths. Your genetics are a strong determinant of your [body weight](https://www.alphabetguides.com/tag/fat-loss/), but they do not determine all of it. Understanding the role your genes have in how easily you can lose (or gain) fat will give you a bit of insight into why people respond differently to the same programme. It will also prevent that fatalistic thinking that you're just a product of your genes. That said, it is true that there *is* a genetic component to obesity. Your genes have been shown to determine around 40-50% of your body weight. The genetic component is lower in people who are of normal weight (i.e., genes determine around 30% of body weight) compared to those who are obese (i.e., genes determine around 70% of body weight).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/33899337/?ref=alphabetguides.com) **But there is no single “fat gene”.** Your body weight (and body fat levels) are influenced by hundreds of different genes. These genes combine and exert a significant influence on how you regulate your weight and fat tissue. Your genes also interact with your environment, meaning certain genes only exert their effects under certain circumstances (e.g., high or low calorie intake, sedentary or [active](https://www.alphabetguides.com/tag/exercise/) lifestyles, high or low [stress](https://www.alphabetguides.com/what-is-cortisol/) states, etc.).[\[2\]](https://www.ncbi.nlm.nih.gov/books/NBK573068/?ref=alphabetguides.com)[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3000924/?ref=alphabetguides.com) Your lifestyle decisions can also influence whether your genes are active or not. This tells us that your genes are influential, but they don’t determine whether you lose, gain or maintain body fat. Having “fat genes” does increase your susceptibilityto gaining fat and makes fat loss more difficult. However, having these genes *doesn't* guarantee that you will be fat or that you *can’t* lose fat at all. **You are more than your genes.** ## How Genes Affect Your Appetite Several genes are thought to affect your [appetite](https://www.alphabetguides.com/appetite-and-body-weight/), satiety levels and food-reward responses. For example:[\[4\]](https://pubmed.ncbi.nlm.nih.gov/25673413/?ref=alphabetguides.com) - A variant of the “*FTO"* gene (found in most people) is *associated* with increased appetite and preferences for [calorie-dense foods](https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/). - A variant of the "*MC4R*" gene can lead to very strong, incessant hunger. This is thought to be one of the most powerful “fat genes” around. - Variants in the “*POMC*" gene are *associated* with more hunger and more frequent [eating behaviour](https://www.alphabetguides.com/fat-loss-beyond-diet-exercise/). Variations in the genes that regulate “satiety hormones” can trick your brain into thinking you need to eat more energy than you actually need. Whereas“hunger gene” variants encourage you to snack more and eat more frequently. ## How Genes Affect Energy Expenditure The amount of energy you “burn” while you rest, work, [sleep](https://www.alphabetguides.com/tag/sleep/), or exercise can vary by hundreds of calories a day. Forty to 80% of the amount of energy you burn (just to keep you going) is influenced by your genes. How efficiently your cells use energy, the number of mitochondria you have, the size of your organs and how active they are are all influenced by your genes.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/33899337/?ref=alphabetguides.com) Thyroid [hormone](https://www.alphabetguides.com/tag/hormones/) is the key regulator of your "metabolic rate". So, differences in some of the genes that regulate it can either increase or decrease thyroid function and thus your metabolic rate. Variations in the "*UCP1"*gene can alter the amount of heat you produce, which means people who “run hotter” will burn more calories. Some genes are also associated with restlessness, fidgeting and the ability to maintain posture, and thus people who have them will generally burn more calories than people who don't.[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3000924/?ref=alphabetguides.com) ## How Genes Affect Fat Storage Besides influencing how much fat tissue you have, your genes also influence *where* you store fat and *where* you lose it from when you burn it (e.g., the *STLM* gene). This is important as *where* the fat is stored can impact both your health risk and what you look like. Your genes can also influence whether you store fat around your abdomen (higher health risk) or your hips and thighs (lower health risk) (e.g., *TBX15* and *HOXC13* genes). The most obvious difference lies in how men and women store fat, due to sex-specific genes (e.g., the *VEGFA* gene).[\[5\]](https://pubmed.ncbi.nlm.nih.gov/28273476/?ref=alphabetguides.com) Your genes also influence whether fat is stored around your organs, known as “visceral” fat (e.g., *PPARG* gene). Even a normal-weight person can be genetically predisposed to storing large amounts of visceral fat. This can also explain why people lose fat from different places, at different rates. Think about those stubborn muffin tops that never seem to go away no matter how much fat you lose.[\[2\]](https://www.ncbi.nlm.nih.gov/books/NBK573068/?ref=alphabetguides.com) Lastly, your genes can also influence the number of fat cells you have and how much energy they can store — so they go on to affect your “storage” capacity of fat. Those with greater storage capacity *may* put on fat more easily and find it more difficult to lose it. [Visceral Fat & Health: Not All Fat is Created EqualVisceral fat is stored around organs. Internal fat is metabolically active and releases substances that are bad for your cardiometabolic health.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-eeef48f9-8e5e-41d9-a18c-0b7e09ceadbc.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1634463278803-f9f71890e67d-b1221270-1c13-44a9-96fe-1a8069441bf1.jpeg)](https://www.alphabetguides.com/visceral-fat/) --- ## How Genes Affect Your Diet and Exercise Habits _This post is for subscribers only._ ### How to Sleep for Muscle Growth & Post-Exercise Recovery URL: https://www.alphabetguides.com/sleep-for-muscle/ Last updated: 2026-09-22T10:03:13.000Z summary - Sleep is a performance enhancer. It's fundamental for optimising muscle growth. You cannot out-train poor sleep. - Sleep supports muscle growth by keeping your hormone and immune system functioning well, as they both peak when you sleep. - Both duration and "quality" of sleep matter. There are several practical strategies available that can improve both components of your sleep. Sleep has two main phases: REM (Rapid Eye Movement) and Non-REM. Non-REM sleep also has three stages of its own: Light Sleep (Stage 1), Deep Sleep (Stage 2) and Deep-restorative Sleep (Stage 3). Your body cycles through all stages approximately 4–6 times each night, averaging 90 minutes per cycle. Approximately 75% of sleep is spent in non-REM sleep, with the majority of this spent in stage 2\. While you're in deep, restorative sleep (stage 3), your body releases loads of [hormones](https://www.alphabetguides.com/tag/hormones/) that directly influence muscle growth. For example, "growth hormone" peaks during the first few hours of sleep, with well over half of your daily growth hormone released during this sleep stage. So, when your sleep is compromised, it generally creates an environment that works against ("antagonistic" to) muscle growth. Sleep deprivation elevates [cortisol levels](https://www.alphabetguides.com/what-is-cortisol/), which promotes "muscle protein breakdown". This impairs recovery, restoration of your energy levels, and interferes with the natural processes that regulate growth. This is why chronically sleep-deprived people often struggle to gain muscle despite consistent training and [adequate nutrition](https://www.alphabetguides.com/muscle-fuel/).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/21550729/?ref=alphabetguides.com) --- ## The Molecular Mechanisms of Sleep Recovery To understand why sleep is so important for muscle growth, we need to know what happens to your body during the night. At a cellular level, good sleep supports the repair processes that underpin the muscle's adaptive response after you [exercise](https://www.alphabetguides.com/tag/exercise/). Unlike during the day, when your body has to focus on multiple competing demands (e.g., work, focus, mental tasks, socialising, eating, chores, *etc.*), sleep allows the body to prioritise muscle repair and muscle growth processes.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/25315456/?ref=alphabetguides.com) Beyond growth hormone and cortisol, sleep is crucial for optimising other hormones involved in muscle regeneration and growth. [Testosterone](https://www.alphabetguides.com/testosterone-and-muscle-growth/), insulin-like growth factor, melatonin and thyroid hormones all increase and peak while you sleep. They all individually have roles in growth and recovery.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/21550729/?ref=alphabetguides.com) [Boost Testosterone Naturally: A 10-Part BlueprintLow energy, mood, libido, training plateaus, or too much body fat? This series will introduce you to practices that are known to increase your T levels.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-8e4c3f87-4558-4f33-8956-63f544c466f5.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1552820755-733e038f86d5-fb9844ab-9796-4d18-9a3d-e38acf753850.jpeg)](https://www.alphabetguides.com/testosterone-blueprint/) Lastly, the inflammatory response to exercise training tends to be misunderstood. Inflammation is required for [muscle growth](https://www.alphabetguides.com/tag/muscle/). But it must be tightly regulated to prevent excessive muscle damage and prolong recovery. Sleep naturally reduces inflammation by synthesising and releasing anti-inflammatory substances. This creates a pro-growth "anti-inflammatory" environment that is required for good recovery. Poor sleep is known to disrupt the immune system and promote inflammation, which in turn impairs repair and muscle growth.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/33400856/?ref=alphabetguides.com) ## Sleep Duration, Quality & Muscle-Centric Outcomes Both “sleep duration” (i.e., how long you sleep) and “sleep quality” (i.e., how well you sleep) affect your muscle health, muscle mass, muscle growth and body composition. Sleeping less than 7 hours per night impairs muscle growth and repair processes, and it also increases cortisol levels and [body fat](https://www.alphabetguides.com/tag/fat-loss/). Poor sleep is also associated with lower strength, poor exercise performance, coordination and stamina (i.e., earlier fatigue). It's a muscle growth killer.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/20921542/?ref=alphabetguides.com) Optimal sleep typically falls within the 7–9 hour range, although different people have their own preferences. Arguably more important than the amount of sleep is the type of sleep you have. “Slow-wave sleep”, which is the deepest stage of non-REM sleep (stage 3), is when the majority of the hormonal, immune and metabolic changes occur, which go on to control the growth and repair of muscle processes. Sleep quality markers are important, such as: - Sleep"**latency**" (i.e., how long it takes you to fall asleep) - Sleep"**fragmentation**" (i.e., how many times you wake during the night) - Sleep "**efficiency**" (i.e., how much time in bed is spent asleep) Lower sleep latency and fragmentation, combined with high efficiency, indicate better sleep quality. These are metrics you should monitor in addition to “how long” you slept. --- ## How to Improve Sleep The good news is that exercise (even high-intensity exercise or weightlifting) naturally improves sleep by itself, both the quality and quantity of it. But in addition to simply exercising, some other basic techniques can help [improve your sleep](https://www.alphabetguides.com/how-to-sleep-better/). _This post is for subscribers only._ ### Move It to Lose It: Exercise & Physical Activity for Fat Loss URL: https://www.alphabetguides.com/exercise-fat-loss/ Last updated: 2026-09-18T12:56:20.000Z summary - Exercise is a tool to improve metabolic health, body composition, and sustainable fat loss. It is not just a method to burn calories. - Resistance exercise maintains energy expenditure. Aerobic exercise and high-intensity exercise improve energy efficiency and health. - NEAT is also a practical, sustainable and underused way to lose fat, potentially burning hundreds of extra calories a day for little effort. The numbers are clear: you’d have to run half a marathon to “burn” a single takeaway meal. So, rather than viewing exercise as simply another way to “burn calories”, you're better off reframing it as a method to improve your ability to manage your body weight, [body fat](https://www.alphabetguides.com/tag/fat-loss/) and your overall health.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/30385379/?ref=alphabetguides.com) ## Exercise and Energy Balance Exercise has mixed effects on weight loss byitself. However, it has substantial effects on your metabolism and appetite. So, it can help with fat loss and maintaining a healthy body weight:[\[2\]](https://pubmed.ncbi.nlm.nih.gov/19127177/?ref=alphabetguides.com) 1. **Immediate energy expenditure:** Even light activities, such as [walking](https://www.alphabetguides.com/why-walking-beats-running/), tai chi, or gardening, can burn 100-200 extra calories an hour. Endurance athletes can burn up to 1,000 calories an hour, training at full tilt.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/30385379/?ref=alphabetguides.com) 2. **Immediately after exercise**, you continue burning calories. Your body doesn’t immediately stop burning calories the moment you step off the treadmill. After a really hard session, you continue burning more calories for hours, possibly hundreds of them.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/21113312/?ref=alphabetguides.com) 3. "**Non-Exercise Activities**": Contrary to common belief, people who exercise regularly are *more* likely to be physically active during the rest of the day.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/29101738/?ref=alphabetguides.com) 4. **Metabolic adaptation**: Exercise training also improves your ability to burn more calories. If you can increase your muscles’ capacity to use carbohydrate and fat.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/33955140/?ref=alphabetguides.com) ### Resistance training and metabolism for fat loss Resistance training provides unique benefits for fat loss, ones that no other exercise modality can replicate. Being able to preserve or increase the amount of [muscle](https://www.alphabetguides.com/tag/muscle/) you have is one of the most critical contributions you can make if you want to lose fat.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/28507015/?ref=alphabetguides.com) Losing 5 kg of muscle might look good on the scales, but it's not so good for your metabolic health, physical condition and your long-term prospects of maintaining your new body weight.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/28507015/?ref=alphabetguides.com) Your muscle has a major role in controlling your "metabolism". One kilogram of muscle contains \~1,200 calories of energy and burns 13-14 calories a day just to maintain it. This means the more muscle you have, the more calories you burn. So, you can eat more and lose the same (or more) fat. Over a year, 5 kilograms of extra muscle burns through the equivalent energy of around 3 kilograms of fat. It also means that you burn more calories when you exercise; larger and more efficient muscles can exercise harder and longer; and you'll also burn more calories after you stop exercising as well.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/34536199/?ref=alphabetguides.com) ### Aerobic exercise: the fat burner In addition to burning large amounts of energy “up front” (i.e., whilst on the treadmill or bike), low-intensity long-duration exercise can also support fat loss. Regular aerobic exercise (at any intensity) increases your muscles’ ability to use more fat and carbohydrate more efficiently; both during exercise *and* at rest. This means they're less likely to be stored as body fat. As you get fitter, you're able to exercise at a higher absolute intensity for longer periods of time, so you burn more calories when you are exercising *and* after you stop exercising.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/23019316/?ref=alphabetguides.com) Even if you are the type of person who doesn't like to exercise, you'll find that doing it regularly will make it easier and potentially more enjoyable. It also has other beneficial effects that (indirectly) support fat loss (e.g., stress reduction, appetite suppression, and [improved sleep](https://www.alphabetguides.com/tag/sleep/)). [What is VO2max & How to Improve ItVO2max is one of the best measures of fitness and health, and the good news is that almost everyone can improve it.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-a024eed9-0521-486b-9fbe-e6e83cbca0c1.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1709601414739-40a3c94cf16e-5b6b3cc8-b8ca-4128-97ba-4d9e1c26fe7f.jpeg)](https://www.alphabetguides.com/improve-your-vo2max/) ## HIIT or MISS: Does High-Intensity Training Burn Fat? High-intensity interval training (HIIT) offers busy people an option that gives them many of the benefits of weightlifting *and* low-intensity exercise in a shorter amount of time. Like the other forms of exercise, HIIT burns calories upfront *and* also after you’ve stopped exercising. However, it can also improve your muscles’ ability to use energy in greater quantities and more efficiently (particularly fats and carbs). And contrary to common belief, it does improve [cardiometabolic health](https://www.alphabetguides.com/tag/heart-health/). But its biggest advantage is that all this can be achieved in a fraction of the time of other types of exercise.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/21113312/?ref=alphabetguides.com) Alas, HIIT is not a panacea. It's not as good for your [muscles](https://www.alphabetguides.com/tag/muscle/) as resistance training is. It also requires more careful planning, as it's not the easiest type of exercise to do (both safely and correctly). It also requires more effort and can take longer to recover from, so it might not be suitable for everyone.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/33955140/?ref=alphabetguides.com) ### Exercise and appetite: a complicated relationship The relationship between exercise and [appetite](https://www.alphabetguides.com/appetite-and-body-weight/) (i.e., your drive to eat) isn’t straightforward. The type of exercise, the intensity, duration and your own unique characteristics all affect it. However, it's generally accepted that it immediately suppresses your appetite for the first few hours after you finish exercising. Low- to moderate-intensity exercise generally has greater and more consistent short-term appetite-suppressing effects. But longer exercise sessions (i.e., over an hour) seem to stimulate appetite and *possibly* increase calorie intake.[\[10\]](https://pubmed.ncbi.nlm.nih.gov/17848941/?ref=alphabetguides.com) The appetite-stimulating effects of exercise seem more common in beginners, females and people who're following a calorie-restricted [diet](https://www.alphabetguides.com/tag/diet/). Some people experience less hunger, while other people feel more hunger (even after performing the same exercise). This highlights the need for there to be some personalisation if you're simultaneously using both dietary and exercise interventions for fat loss. ## Summary Exercise is a tool for achieving and maintaining good metabolic health, body composition, and sustainable fat loss. It's not just a method to burn calories. Resistance exercise helps maintain energy expenditure. Aerobic exercise and high-intensity exercise burn more calories and improve cardiometabolic health. Exercise typically suppresses appetite. But intensity, duration, training history and some personal characteristics can all affect how your appetite responds. #### Exercise for Weight Loss: Current Recommendations[\[2\]](https://pubmed.ncbi.nlm.nih.gov/19127177/?ref=alphabetguides.com) - ****Resistance exercise**: 2+ sessions a week on non-consecutive days. - ****Aerobic exercise**: 150+ minutes a week or 30+ minutes a day, 3+ days a week, **or** - ****High intensity exercise**: 75+ minutes a week or 25+ minutes a day, 2+ days/week --- ## NEAT for Fat Loss: The Unseen Fat Burner “Non-Exercise Activity Thermogenesis” (NEAT) is the scientific term for a simple part of your daily energy expenditure. It's generally underappreciated and overlooked, as a lot of attention is (rightly) given to formal exercise. However, the “non-exercise” part of your daily activity (e.g., work, travel, maintaining posture, fidgeting) can account for 15-30% of your total energy expenditure.[\[11\]](https://pubmed.ncbi.nlm.nih.gov/12468415/?ref=alphabetguides.com) There's a massive disparity in NEAT between people (up to 800 calories a day), which helps explain why some people lose fat more quickly or more easily than others. Those with higher NEAT have an advantage that can rival a daily exercise session.[\[12\]](https://pubmed.ncbi.nlm.nih.gov/9880251/?ref=alphabetguides.com) ### The science behind NEAT NEAT works in many ways that extend far beyond simple "calories out". The primary driver of NEAT is the amount of “spontaneous” (i.e., unplanned) physical activity you do. This is determined by the part of your brain that monitors your [hormones](https://www.alphabetguides.com/tag/hormones/), environment and how much energy you have available to use. It operates beyond your control. So you can burn more (or less) NEAT calories without even realising it. When some people eat too much food, they subconsciously increasetheir NEAT in response. They might move more, fidget more, or change their posture to burn more energy. This can, in part, explain why some people can consume a lot of calories and don’t seem to gain weight.[\[13\]](https://pubmed.ncbi.nlm.nih.gov/37092376/?ref=alphabetguides.com) Even without moving an extra inch, some people can burn off excess calories, at a cellular level, by simply producing more heat, so you won't even notice it. Your body does this via a process called “brown adipose tissue thermogenesis”. Lucky for some! There’s a strong genetic component to NEAT. However, it can also be influenced by your behaviour and environment. That’s what we’ll focus on. #### How many NEAT calories do some common activities burn?[\[10\]](https://pubmed.ncbi.nlm.nih.gov/17848941/?ref=alphabetguides.com) - Figiting seated: \~125 calories an hour - Figiting standing: \~160 calories an hour - Light chores (cleaning, gardening, cooking): \~150 calories an hour - Slow walking: \~175 calories an hour - Brisk walk: \~300 calories an hour ### Assessing and increasing your NEAT Scientific ways of measuring NEAT are not accessible to most people. This makes tracking and monitoring it difficult in real life. But there are things you can do to help understand your NEAT better.[\[13\]](https://pubmed.ncbi.nlm.nih.gov/37092376/?ref=alphabetguides.com) - Step counters and fitness trackers are good indicators of your NEAT, but they're not perfect. - The physical demands of your job and daily activities are usually the largest source of NEAT. People with moderately active occupations (i.e., working on their feet) can burn 300-500 calories a day more than those who are seated. - Observe your behaviour: do you pace when on the phone, tap your feet while seated, shuffle around in your chair, change your posture often, or take stairs instead of the lift? NEAT is really about many little things adding up throughout the day. - Your environment can also influence NEAT. Exposure to cold temperatures, non-seated workstations and cluttered living spaces (which require navigation and longer walking routes) can increase NEAT. Conversely, prolonged sitting, warm environments, and the use of convenient living devices can reduce it. Increasing your NEAT needs to fit in with your daily lifestyle and needs to be sustainable. Some examples can include: - Running the temperature of your environment *slightly* colder than normal. This is also good for your energy bills and the environment. - Cold showers and getting outdoors are typically good for NEAT if you don’t have access to the thermostat. - Standing workstations can burn an extra 50-100 calories an hour. - Position items you use a lot (e.g., your phone, TV remote or keys) in a place you have to get up and walk to reach. - Park further away from work or home. Get off one stop early and walk. Take walking meetings as Socrates did. - Stress balls, desk fidget toys, and regular drink or refill breaks work at work. ### NEAT for fat loss Maintaining your usual (or ideally higher) energy expenditure is critical for successful fat loss. And NEAT offers some advantages, beyond just increasing energy expenditure. *Some* types of exercise stimulate your appetite and reduce daily activity, whereas increasing your NEAT does not. The timing of NEAT activity throughout the day can also matter. Spreading bouts of NEAT throughout the day burns more calories than doing a few longer bouts of NEAT between periods of sitting. But any extra NEAT will be beneficial. ### Main barriers to increasing NEAT Modern environments are designed to *minimise* NEAT by encouraging convenience and sedentary behaviour. Most modern technologies are NEAT suppressors. Think about it: smartphones, TV, streaming services, home delivery, and online shopping have all contributed to reduced NEAT, which previous generations never experienced. So, adding movement breaks and choosing analogue alternatives can be effective at getting NEAT back into your life. Busy lifestyles are a major reason for low energy expenditure. So, look at increasing your NEAT into (not in addition to) your everyday activities (e.g., standing desks, colder temperatures, walking meetings). NEAT tends to work best alongside other lifestyle changes (e.g., diet and exercise). It is *not* a replacement for structured exercise. But the main benefit of NEAT, compared to planned exercise, is that it is more accessible, flexible, and sustainable.[\[13\]](https://pubmed.ncbi.nlm.nih.gov/37092376/?ref=alphabetguides.com) Over time, NEAT habits can become “ingrained” as an unconscious habit, so it becomes effortless; just part of your new daily routine. View NEAT as an insurance policy. It is a tool that hums away in the background, burning calories irrespective of the other lifestyle decisions you make that day. ### Summary NEAT contributes substantially to your daily energy expenditure, potentially hundreds of extra calories. It is determined both "subconsciously" and by your behaviour (e.g., energy balance, hormones, occupation, environment, and habits). Increasing NEAT is practical and sustainable, and offers fat loss benefits with little (relative) effort. However, it should complement, not replace, formal exercise. --- ## Resistance Training: Lifting Weights to Lose Weight _This post is for subscribers only._ ### How Basal Metabolic Rate (BMR) Affects Weight Loss & Health URL: https://www.alphabetguides.com/basal-metabolic-rate/ Last updated: 2026-09-18T17:38:19.000Z summary - BMR is the largest part of your daily energy expenditure. But it varies and can change with diet, body composition, and health. - “Adaptive thermogenesis” makes fat loss harder: extreme calorie-restriction diets can lower your BMR, explaining why they often fail. - Protecting muscle mass and avoiding extreme deficits helps maintain your BMR and makes losing (or maintaining) body fat easier. Your body needs energy to maintain its basic functions, even while you rest or sleep. Just keeping your body going is actually the most energy-demanding part of your daily energy expenditure. It’s commonly referred to as your “Basal Metabolic Rate” (BMR) or sometimes “Resting Metabolic Rate” (RMR). Your BMR runs 24 hours a day, 7 days a week, from conception until death. It burns energy whilst you sleep. It burns energy whilst you’re awake. It can adapt, change, and be manipulated to support and promote sustainable [fat loss](https://www.alphabetguides.com/tag/fat-loss/).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/16277824/?ref=alphabetguides.com) ## How BMR Affects Weight Loss The formal definition of BMR is the energy required to maintain vital physiological functions in a 1. Fasted “post-absorptive" state, 2. At rest 3. In a normal temperature environment 4. With no (or minimal) outside "stress" (e.g., noise, threats, any acute injury or illness). It is usually expressed in kilocalories per day (kcal/day), and it is basically the energy used by all your cells and the organs they make: your heart, your lungs, your muscles, your kidneys, liver, brain, and everything else. For most people, BMR accounts for **60-75%** of their “total daily energy expenditure” (TDEE). And as far as losing (or maintaining) body fat, it's really the metabolic “baseline”.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/16280423/?ref=alphabetguides.com) The calculation of BMR can be used to predict your calorie needs, set appropriate targets, and understanding how it works can explain why weight loss isn’t always as easy as it sounds. ## How to Calculate Your BMR BMR is typically calculated using “prediction equations”. There are several equations available; all have their pros and cons, and different levels of complexity. Simply multiplying your body mass in kilograms by 24 (for men) or 22 (for women) is the most basic formula. So a 100 kg man would have a BMR of \~2,400 kcal a day. But other prediction equations can take into account your age, sex, height, and the amount of fat and muscle you have (i.e., your “body composition”). If you want a slightly more accurate BMR estimation, you can use the Henry-Oxford equations:[\[3\]](https://pubmed.ncbi.nlm.nih.gov/15883556/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/16277825/?ref=alphabetguides.com) ### Men - **Ages 18–30:** BMR = (15.057 × Weight, kg) + (6.923 × Height, cm) - 381 - **Ages 30–60:** BMR = (11.472 × Weight, kg) + (8.696 × Height, cm) - 577 - **Ages 60+:** BMR = (11.711 × Weight, kg) + (6.756 × Height, cm) - 581 ### Women - **Ages 18–30:** BMR = (14.818 × Weight, kg) + (4.866 × Height, cm) - 390 - **Ages 30–60:** BMR = (8.182 × Weight, kg) + (5.023 × Height, cm) - 11.6 - **Ages 60+:** BMR = (8.520 × Weight, kg) + (4.208 × Height, cm) + 10.7 So a 70 kg female who's 160cm tall and 35 years old would have her BMR calculated as 1,364 kcal a day = \[(8.182×70)+(5.023×160) - 11.6\]. The more complicated formulas *generally* provide a more accurate estimation of your “true” BMR. However, even the most complex equations can still have large errors (\~10 % or 200-300 kcal/day). So these equations should just be used as a guide, or “educated guess”, rather than an exact number. #### What Determines or Affects Your BMR - Taller people have higher BMR - Heavier people have higher BMR - Older people have lower BMR - Men have a higher BMR than women - Many genes and hormones control BMR - People with more [muscle](https://www.alphabetguides.com/tag/muscle/) have higher BMR - Cold temperatures increase BMR - Calorie restriction decreases BMR - Poor [sleep](https://www.alphabetguides.com/tag/sleep/) decreases BMR --- ## How Adaptive Thermogenesis Affects Weight Loss “Adaptive thermogenesis” is the technical term for the body’s response to [sudden decreases](https://www.alphabetguides.com/crash-diet/) in your energy intake. It does this to defend *against* any further weight loss. This is often overlooked when you're doing your calorie counting and calorie-deficient diet. It is an error to assume that your BMR doesn’t change; it does! Your body doesn’t like sudden and drastic changes to its environment, even if it technically needs it (for your health). Therefore, it will sometimes resist change by decreasing your BMR. This is great for survival purposes, but not so much when you want to lose a significant amount of body fat.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/20935667/?ref=alphabetguides.com) In response to severe calorie restriction, your body can reduce its BMR by 10–20%, and up to \~30% in extreme circumstances. For our 100 kg person, that could be around 500 kcal a day.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/19198647/?ref=alphabetguides.com) It does this by dialling down the energy use of your organs and altering the [hormone levels](https://www.alphabetguides.com/tag/hormones/) that regulate BMR (e.g., thyroid hormone, adrenaline, and noradrenaline). This means your body starts working more efficiently, as it has fewer resources. This response can occur within the first few days of a crash diet and can actually persist for months or even years after stopping it. It also explains why weight regain is common amongst dieters (i.e., “[yo-yo dieting](https://www.alphabetguides.com/yoyo-diet/)”), making long-term weight loss and maintenance challenging. Not everyone’s BMR responds in the same way to [calorie restriction](https://www.alphabetguides.com/hara-hachi-bu-an-ancient/). Some people can actually only have small decreases in BMR, meaning they’ll lose more weight than other people, even if they're eating the same calories. There’s also a genetic component that determines whether you maintain (or possibly increase) your BMR while you lose weight. However, there are also things you can do yourself.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/16280423/?ref=alphabetguides.com) ## How to Optimise Your BMR for Weight Loss _This post is for subscribers only._ ### 6 Healthy Mediterranean Diet Meat & Egg Recipes URL: https://www.alphabetguides.com/mediterranean-meat-dairy/ Last updated: 2026-08-18T08:00:06.000Z --- ## 1\. Chicken Souvlaki Chicken Souvlaki is a popular Greek street food. It’s marinated chicken threaded onto skewers and char-grilled. Souvlaki “style” can be done with any meat, and represents the Mediterranean diet's approach to eating meat in moderation, pairing it with vegetables, and using light but distinct flavours rather than heavy sauces. The chicken is a great source of lean protein. It's traditionally served wrapped in warm flatbread with a Greek-style salad and tzatziki. The marinated meat can be prepared well in advance and sit ready for grilling on the BBQ or griddle pan. recipe information - ****Serves:** 4 - ****Time:** 2 hours (+ 2-6 hours marinating time) - ****Cost:** \~$2.50 per serving - ****Calories: \~**380 kcal per serving - ****Source of:** Protein, Phosphorus, Selenium, Vitamin B3, B9 ### Ingredients - 800g (1¾ lb) boneless, skinless chicken, evenly cubed - 100ml (½ cup) extra-virgin olive oil - 2 lemons - 4 garlic cloves, minced - 2 tsp dried oregano - 1 tsp paprika - Flatbread, Greek salad and tzatziki, for serving ### Instructions 1. In a large bowl, whisk together the extra-virgin olive oil, juice of 2 lemons, garlic, oregano, paprika, salt, and pepper. Add the chicken pieces and toss to coat thoroughly. Cover and refrigerate for at least 2 hours (ideally 4–6 hours, or longer). The lemon juice tenderises the chicken. 2. If you’re using wooden skewers, soak them in water for 30 minutes to prevent burning. Remove the chicken from the fridge 20 minutes before cooking to take the chill off (to ensure even cooking) 3. Thread the chicken pieces onto skewers, leaving small gaps between each piece. Don't pack them too tightly or the centres won't cook evenly. You should get 5–6 pieces per skewer. 4. Preheat your BBQ, griddle (or pan) to medium-high heat. Oil the pan, grill, or griddle lightly to prevent sticking and get those signature char-marks. This is what gives the Souvlaki its unique look and flavour. 5. Grill the skewers for 10–12 minutes total, turning every 3–4 minutes to ensure all sides develop colour. The chicken should be golden with slightly charred edges and cooked throughout. Don't overcook; we don’t want the meat to become dry. 6. Remove from heat and let rest for 3–4 minutes. Squeeze fresh lemon juice over the skewers and serve immediately with warm flatbread, Greek salad and a generous dollop of tzatziki. --- ## 2\. Keftedes Keftedes are Greek herb-scented meatballs. They should be tender, aromatic and are found in tavernas from Athens to Crete. Unlike their Italian meatball cousins, Greek keftedes are different in that they include fresh mint, lemon, cumin and oregano. They appear in a meze with tzatziki, inside a flatbread with tomatoes and onions, or served as a main course with potatoes and herbs. The lean red meat provides high-quality protein, iron, and B vitamins, particularly B12\. When shallow-fried in extra-virgin olive oil rather than deep-fried, keftedes align beautifully with Mediterranean principles of using quality fats and meat in moderation. Serve hot or at room temperature, or cold as a quick, ready-to-go snack. recipe information - ****Serves:** 4 - ****Time:** 1 hour - ****Cost:** \~$2 per serving - ****Calories: \~**420 kcal per serving - ****Source of:** Protein, Iron, Selenium, Zinc, B12 ### Ingredients - 500g (1 lb) minced beef and/or lamb - 1 onion, finely grated - 2 garlic cloves, minced - 1 egg, lightly beaten - 50g (½ cup) breadcrumbs or torn stale bread soaked in water and squeezed - Large handful of fresh mint, finely chopped - 2 tbsp fresh oregano, or 1 teaspoon dried - 1 tsp ground cumin - Zest of 1 lemon - 80ml (⅓ cup) extra-virgin olive oil, for frying ### Instructions 1. In a large bowl, combine the meat, grated onion, garlic, egg, breadcrumbs, mint, oregano, cumin, lemon zest, salt, and plenty of black pepper. Using your hands, mix gently but thoroughly until everything is evenly distributed; stop once combined. 2. Cover and refrigerate for at least 30 minutes, or up to 4 hours. This rest allows the breadcrumbs to absorb moisture and the flavours to meld, resulting in meatballs that hold together better during cooking and taste more cohesive. 3. With dampened hands to prevent sticking, shape the golf ball-sized balls. You should get 16–20 keftedes. Pat the meatballs with some kitchen paper to remove any moisture from the surface. This creates a golden crust and helps them hold their shape. 4. Heat the extra-virgin olive oil in a large, heavy frying-pan over medium heat. Working in batches to avoid crowding, add the keftedes and fry for 8–10 minutes total, turning occasionally until deep golden brown on all sides. 5. Transfer cooked keftedes to a plate lined with paper towels to drain briefly. They shouldn't be greasy if the oil temperature was correct. Keep warm in a low oven while you finish frying the remaining batches. 6. Serve hot or at room temperature with lemon wedges for squeezing and a bowl of tzatziki for dipping or drizzling. --- ## 3\. Shakshuka Shakshuka is a North African [breakfast](https://www.alphabetguides.com/mediterranean-breakfast-ideas/). It’s a frying pan filled with eggs poached in spiced tomato sauce that is eaten from Tunisia to Israel and beyond. The name comes from Arabic, meaning “a mixture", which perfectly describes this rustic dish where peppers, tomatoes, and aromatic herbs and spices combine into a fragrant sauce cradling softly poached eggs. The eggs provide high-quality protein, choline, and B vitamins, while the bell peppers add vitamins A and C along with antioxidants, and the warm spices like cumin and paprika contain anti-inflammatory compounds. Serve shakshuka straight from the frying-pan with warm pita or crusty bread for scooping, perhaps with olives and fresh herbs on the side. recipe information - ****Serves:** 4 - ****Time:** 10 minutes - ****Cost:** \~$1.25 per serving - ****Calories: \~**320 kcal per serving - ****Source of:** Protein, Fibre, Selenium, Vitamin A, C, B2, K ### Ingredients - 6 large eggs - 800g (28 oz) tin chopped tomatoes, or 6 fresh tomatoes, grated - 2 red bell peppers, diced - 1 large onion, finely chopped - 4 garlic cloves, minced - 80ml (⅓ cup) extra-virgin olive oil - 2 teaspoons ground cumin - 1 teaspoon sweet paprika - ½ teaspoon ground caraway (optional) - Pinch of cayenne pepper or red chilli flakes - Small bunch of coriander or parsley, chopped ### Instructions 1. Heat the extra-virgin olive oil in a large, deep frying-pan or cast-iron pan over medium heat. Add the onion and cook for 7–8 minutes until softened and lightly golden. Add the bell peppers and cook for another 5 minutes until they begin to soften. The vegetables should be soft. 2. Add the garlic and the spices. Stir for 1 minute until the spices are fragrant and coat the vegetables; this releases their oils and deepens the flavour. 3. Pour in the tomatoes and bring to a simmer. Cook uncovered for 15–20 minutes, stirring occasionally, until the sauce thickens and the oil begins to separate at the edges. The sauce should be rich, concentrated, and jammy, not watery. You can make this ahead of time. 4. Taste and adjust the seasoning before adding the eggs. Create six small wells in the sauce using the back of a spoon, spacing them evenly around the pan. These wells help contain the eggs and prevent them from running together. 5. Carefully crack an egg into each well. Season the eggs lightly with salt and pepper. Reduce the heat to medium-low, cover the pan, and cook for 5–7 minutes. Check after 5 minutes; the egg whites should be set, but the yolks should still be runny. 6. Remove from the heat and scatter with the fresh herbs. Serve immediately, bringing the pan directly to the table. Provide warm bread for scooping up the spiced tomato sauce and breaking into the egg yolks. ![Pan full of Shakshuka.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1590412200988-a436970781fa.jpeg) --- ## 4\. Yoghurt Parfait A simple "parfait" transforms breakfast or dessert into something nourishing and indulgent. This recipe is thick, tangy yoghurt layered with crunchy nuts, honey, and red berries. While parfaits may seem modern, the Mediterranean has long celebrated yoghurt with honey and nuts. Greek yoghurt provides [high-quality protein](https://www.alphabetguides.com/plant-based-diet-meal-plan/), probiotics for gut health, and calcium for bone health. The mixed nuts contribute [heart-healthy](https://www.alphabetguides.com/tag/heart-health/) fats, vitamin E, magnesium, and protein, while berries deliver powerful antioxidants, vitamin C, and fibre. Raw honey adds natural sweetness along with enzymes and antimicrobial properties. This balanced parfait is perfect for breakfast, a midday snack, or a light dessert. recipe information - ****Serves:** 4 - ****Time:** 15 minutes - ****Cost:** \~$1.25 per serving - ****Calories: \~**380 kcal per serving - ****Source of:** Protein, Fibre, Probiotics, Calcium, Magnesium, Iron, Vitamin C, E ### Ingredients - 600g (2½ cups) thick Greek yoghurt, full-fat or 2% - 150g (1 cup) mixed fresh berries (strawberries, raspberries, blueberries) - 100g (¾ cup) mixed nuts (almonds, walnuts, pistachios), roughly chopped - 80ml (¼ cup) raw honey - 2 tablespoons mixed seeds (pumpkin, sunflower, or sesame) - Fresh mint leaves for garnish (optional) - Pinch of ground cinnamon (optional) ### Instructions 1. Toast the chopped nuts in a dry pan over medium heat for 3–4 minutes, stirring frequently, until fragrant and lightly golden. Transfer to a plate to cool completely, as warm nuts will make the yoghurt watery. 2. If using strawberries, hull and slice them. Leave smaller berries like raspberries and blueberries whole. If the berries aren't particularly sweet, you can macerate them by tossing them with a teaspoon of honey and letting them sit for 10 minutes. 3. In serving glasses or bowls, spoon a generous layer of Greek yoghurt as the base (about a third of the total amount per serving). The thick, creamy yoghurt should be cold and tangy, providing the foundation that contrasts with the other textures and flavours. 4. Drizzle honey over the yoghurt layer; don't be shy with it. Use the best quality honey you can afford. Scatter some toasted nuts, seeds, and berries over the honey, creating distinct pockets of flavour and texture rather than mixing everything uniformly. 5. Repeat the layering process—another layer of yoghurt, more honey, nuts, seeds, and berries. Build 2–3 layers depending on your glass size, finishing with berries, a scattering of the most attractive nuts, and a light pinch of cinnamon (optional) 6. Finish with a final drizzle of honey over the top, and tuck in a fresh mint leaf (optional). The parfait can be assembled up to 2 hours ahead and refrigerated, though it's best enjoyed within an hour to maintain the nuts' crunchy texture. Serve immediately with a long spoon, so each mouthful captures all the layers. --- ## 5\. Spinach Frittata The frittata is Italy's answer to the omelette. It’s a thick, open-faced egg dish that works for breakfast, a picnic, or an “antipasto” spread. This is the “Florentine” version, which has spinach in it. This dish celebrates Tuscany's love of its greens and simple flavours. Unlike French omelettes that demand attention and skill, the frittata is a bit more forgiving and flexible, which makes it great for home cooks. The eggs provide high-quality protein and choline for [brain health](https://www.alphabetguides.com/tag/brain-health/), while spinach gives us iron, folate, and vitamins A and K. This dish is typical of the Mediterranean approach to eggs and other animal protein — they're used to complement the plants rather than being the centrepiece. Serve warm or at room temperature with a simple [green salad](https://www.alphabetguides.com/superfood-leafy-greens/) and crusty bread for lunch, or cut into wedges for a quick, tasty appetiser. recipe information - ****Serves:** 4 - ****Time:** 25 minutes - ****Cost:** \~$1 per serving - ****Calories: \~**280 kcal per serving - ****Source of:** Protein, Calcium, Selenium, Vitamin A, B9, K _This post is for subscribers only._ ### Canola vs Olive Oil: Best Oil for the New Western Diet URL: https://www.alphabetguides.com/canola-vs-olive-oil/ Last updated: 2026-10-11T12:47:20.000Z key takeaways - Both canola (or rapeseed) oil and olive oil are healthier than tropical plant oils (e.g., coconut, palm oil) and animal fats (e.g., butter, lard). - Canola oil is slightly better at lowering cholesterol than olive oil. But olive oil still has the strongest health outcomes (at the moment). - However, canola oil is a more sustainable, affordable, accessible and secure source of fat than olive oil for people in Western countries. The [health benefits of olive oil](https://www.alphabetguides.com/superfood-olive-oil/) have been known for decades. It has been the primary fat source used in the Mediterranean diet for centuries, probably millennia. There's now a large body of evidence linking olive oil intake to lower rates of [heart disease](https://www.alphabetguides.com/tag/heart-health/), cholesterol, type 2 diabetes, some cancers, lower inflammation, and longer, healthier lives in humans. Canola oil (sometimes called rapeseed oil) does not receive as much attention. This is probably because it hasn't traditionally been part of wider healthy eating patterns like olive oil has (i.e., the [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/)). However, when you directly compare it to olive oil, its nutrient content and health benefits are comparable (but not identical). So which one should you use? In this article, we'll have a look at the nutrient profile, health outcomes and then wider issues that may not be directly related to your health, but are important nevertheless. ## Canola vs. Olive Oil Both canola oil and olive oil are "unsaturated fats". And as far as nutrition is concerned, they beat animal fats and tropical oils quite easily. Olive oil is mostly one type of fat: oleic acid, a monounsaturated fat. But it also contains several unique "polyphenols" that are good for your health. Canola oil has a uniquefat profile containing a lot more of a plant-based omega-3 ("alpha-linolenic acid" or "ALA" for short) and a bit more omega-6 ("linoleic acid") and vitamin E. They are both low in saturated fat. In humans, canola oil is more effective at lowering the "bad" (LDL) cholesterol and total cholesterol. But again, both oils beat animal fats and tropical oils, which actually *increase* LDL cholesterol levels and [body weight](https://www.alphabetguides.com/tag/fat-loss/).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/35866510/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/30006369/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/25403327/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/38370114/?ref=alphabetguides.com) In fact, people who replace animal fats and tropical oils with canola oil can expect decreases in liver fat, [belly fat](https://www.alphabetguides.com/candy-apple-phenotype/), a better blood lipid profile, metabolic health and lower chances of heart attacks.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/38370114/?ref=alphabetguides.com) 💡 Canola oil has a higher content of "phytosterols" compared to many other oils. Potentially explaining the specific (cholesterol-lowering) health benefits. So, canola oil beats olive oil in *some* of the key health markers. And both beat animal fats and tropical oils. However, healthier people, who live longer and have lower disease rates, still tend to use olive oil as their primary fat.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/38370114/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/35027106/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/32147453/?ref=alphabetguides.com) This may be due to the high content of antioxidant polyphenols found in olive oil, which aren't present in canola oil. These polyphenols lower inflammation, which seems to underpin a lot of the big diseases (e.g., cancer, cardiovascular disease, dementia) and life expectancy. To summarise, canola oil probably beats olive oil for lowering cholesterol, and would probably have more health benefits for people with higher cholesterol levels. But olive oil probably has the strongest and most effective all-around health benefits. If you're solely focused on general health, olive oil wins. However, the direct and general health benefits aren't the only factor. Any advice must survive in the real world. If we give advice and no one follows it, or they can't follow it (even if they wanted to), it has zero use. We also have to consider prices, supply chains and production. This is where the picture starts to shift. ## Can the West Rely on Olive Oil? About 80% of the world's olive oil comes from a few Mediterranean countries. Spain alone usually supplies 40%. In our opinion, it is not a viable or secure option for the West. What if a drought or intolerable heat hit Spain, or the other olive oil-producing countries? What will happen to the price? This has already happened, and we've seen olive oil [price increases](https://www.cnbc.com/2026/07/17/spain-olive-oil-europe-heat-climate.html?ref=alphabetguides.com) across the West. People simply can't afford it. So they won't buy it. And they won't eat it. We don't think that (currently) the West can rely on olive oil as its *primary* fat source. If you import someone else's food product, you'll also import someone else's food security risks (in addition to your own). Higher prices have other hidden costs. They incentivise bad people to cheat. Extra virgin olive oil is one of the [most faked foods](https://www.bbc.co.uk/news/articles/c2e102vw1z2o?ref=alphabetguides.com) in the world. It's cut with cheaper oils and mislabelled. Scientists can detect this (*ex post facto*), but supermarkets and shoppers can't. This is not a reason to completely avoid importing or buying it, but it's a reason why you can't solely *rely* on it as a primary fat. --- ## The Case for Canola Oil: Built for the West ### #1\. It's already grown here, at scale Canola (or rapeseed) is not an exotic crop. It was actually introduced to Europe by the Romans. To grow it on a mass scale, it doesn't need new farmland, farming methods, or factories. Nearly all Western countries already grow and process it into oil — millions of tonnes a year. It is already on the supermarket shelves, and Western shoppers seem to have (tentatively) been using it. There is definitely room to expand production. And we can't think of a good reason why it couldn't be the primary source of fat across the West. Cost, freshness, accessibility and food security matter: canola oil can meet all four. ### #2\. The environmental impact Good news. Of all the main cooking oils, canola oil has the *lowest* carbon cost. This is certainly true when produced at scale compared to olive oil, requiring a lot less water (about a half to a third of the amount).[\[7\]](https://pubmed.ncbi.nlm.nih.gov/35302036/?ref=alphabetguides.com) In a hotter, drier Mediterranean climate, that water demand is exactly what keeps causing harvest failures. This may get worse going into the future if the climate scientists' predictions are correct. ### #3\. Canola oil is already tested: Lessons from the Nordic diet A couple of decades ago, Nordic scientists, dietitians, and chefs faced the same choice. They wanted a healthy diet built on only what Scandinavia could grow itself. Olive trees don't survive Nordic winters. Rapeseed does. So the "[New Nordic Diet](https://www.alphabetguides.com/nordic-diet/)" chose rapeseed (or canola) oil instead of olive oil.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/22251407/?ref=alphabetguides.com) The reason is simple: it was the healthiest oil that they could grow. They wanted to be able to control their environmental footprint and not import their fat from elsewhere. They want food security and a product that conforms to their own standards that come with growing their food at home. The creators of the Nordic diet are blunt about it. Although olive oil has marginally better health benefits, canola oil is the better option for everyday use. Olive oil (marginally) wins on the clinical tests and the lab tests. But canola oil wins in the field.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/31540525/?ref=alphabetguides.com) The bigger Western countries can do the same. None of them can grow olive oil at scale, but all of them already grow oilseed rape. If the Nordic countries can build their own healthy, locally grown diet around it, we believe the rest of the West can do the same. --- ## So which oil should you actually buy? _This post is for subscribers only._ ### Creatine Supplements for Muscle Growth: Do They Work? URL: https://www.alphabetguides.com/creatine-muscle/ Last updated: 2026-10-02T14:21:56.000Z summary - Creatine increases your energy, leading to longer, harder, more intense exercise performance and, ultimately, more muscle growth. - Creatine is a safe, well-tolerated and well-researched supplement that supports muscle growth in healthy adults. - Optimal dosing is 3–5 grams a day of a creatine monohydrate supplement, as natural food sources won't provide enough. Creatine is a natural compound that's produced by the body, specifically in your liver and kidneys, and a little bit in your pancreas. It is a simple compound made from three [amino acids](https://www.alphabetguides.com/amino-acids-muscle/): arginine, glycine, and methionine. It is found in small amounts in meat and fish that you eat (anywhere from 0.4–1.8 grams per 100 grams of meat or fish). Creatine is also found in your own [muscles](https://www.alphabetguides.com/tag/muscle/), where it serves a simple but important function: energy. When you lift a weight, sprint, or perform any short, explosive form of [exercise](https://www.alphabetguides.com/tag/exercise/), your body turns to a quick energy source called the “adenosine triphosphate phosphocreatine system” (ATP-PCr). In this energy system, creatine phosphate "donates" a phosphate group to regenerate **ATP**, which is the energy source that your body ultimately runs on. Without enough creatine, this energy system runs out of ATP quickly, and you’ll get tired and start to fatigue. So, the more creatine that's stored in your muscles, the more energy you’ll be able to generate. And if you have more energy in your muscles, you should be able to do high-intensity exercise [longer and harder](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/). So, the most obvious benefit of creatine supplementation is performance. Creatine supplementation has been shown to consistently improve multiple performance metrics. This includes strength, sprint speed, muscular endurance, and total training volume.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/28615996/?ref=alphabetguides.com) In practice, this might mean completing a few more reps per set or a few more sets per session. You may also [recover faster](https://www.alphabetguides.com/rest-and-body-composition/) between sets or feel less fatigued during workouts. This might seem like a small gain (which it is). But when this is applied consistently over a few months, these small gains compound. More exercise, be that reps, sets, or weight, means more work. More work, over weeks and months, means more muscle. Research shows that when combined with [resistance exercise](https://www.alphabetguides.com/resistance-training-beginners/), 6–12 weeks of creatine supplementation can add an extra kilogram of muscle.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/35986981/?ref=alphabetguides.com) #### Five Proven Benefits of Creatine! 1. Improves high-intensity exercise performance 2. Increases work or volume performed during training 3. Increases muscle mass, muscle growth, and [muscle strength](https://www.alphabetguides.com/muscle-adaptation/) 4. Increases energy availability and muscular endurance 5. Accelerates recovery from exercise. --- ## Creatine & Water Retention: Is it Just Water Weight? Besides increasing your energy levels and exercise capacity, creatine also increases muscle growth by drawing fluid into your [muscle cells](https://www.alphabetguides.com/muscle-fibre-types/). Yes, this *is* water weight, but it's *not* bloating. The water is *inside* your muscle, not under your skin. This makes muscles appear fuller and larger, even before you've actually started building new muscle "tissue". Some scientists also think that the swelling of the muscle alone can actually stimulate muscle growth by itself! So there's potentially a 3-prong benefit of taking creatine: 1. It stimulates more muscle growth via increased work capacity 2. It increases the size of the muscle by increasing "intracellular" water retention 3. The increased water retention potentially stimulates muscle growth further. ## Creatine-Rich Foods: Can You Get Enough You probably cannot get enough creatine from your diet alone. You’d need to eat a large amount of steak or [salmon](https://www.alphabetguides.com/superfood-oily-fish/) to get about 1 to 2 grams of creatine every day. Compare this to the typical effective dose for supplementation, which is 3–5 grams a day. For athletes, vegetarians, or anyone training hard, relying on food alone is rarely enough. Creatine, particularly creatine monohydrate (the most researched form of creatine), is inexpensive, well-tolerated, and effective. More expensive forms like creatine HCl, ethyl esters, or buffered creatine often claim superior effects; however, there's little *consistent* evidence to suggest that they are better for muscle growth than plain old creatine monohydrate.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/33557850/?ref=alphabetguides.com) #### What foods are high in creatine?[\[4\]](https://pubmed.ncbi.nlm.nih.gov/21346331/?ref=alphabetguides.com) - ****Herring:** 2–4 grams per serving (225g) - ****Lean Beef:** 1.5–2.5 grams per serving (225g) - ****Salmon:** 1.5–2.5 grams per serving (225g) - ****Pork:** 1.5–2.5 grams per serving (225g) - ****1% Milk:** 0.05 per serving (225g) ## How to Take Creatine: Dosing Options _This post is for subscribers only._ ### 5 Plant-Based Mediterranean Diet One-Pot Recipes URL: https://www.alphabetguides.com/mediterranean-one-pot/ Last updated: 2026-08-31T09:17:12.000Z ## 1\. Ribollita Ribollita, meaning “reboiled”, is a Tuscan bread and vegetable soup that transforms leftovers into something tasty. The dish was born from the peasants’ practice of stretching minestrone soup out by adding stale bread and reheating it the next day. Ribollita has become one of Italy's most celebrated dishes. The bread dissolves into the soup, creating a thick porridge-like consistency that's more stew than soup. The dish captures the Mediterranean ethos of resourcefulness, frugality and [plant-based eating](https://www.alphabetguides.com/tag/plant-based/). The beans provide [plant protein](https://www.alphabetguides.com/tag/protein/), fibre, and folate, while the “cavolo nero” (Tuscan kale) has vitamins A, C, and K along with calcium and iron. The variety of vegetables contributes additional fibre, antioxidants, and phytonutrients. Serve ribollita with a drizzle of [extra-virgin olive oil](https://www.alphabetguides.com/superfood-olive-oil/) and (optionally) some grated Parmesan. recipe information - ****Serves:** 6 - ****Time:** 1 hour - ****Cost:** \~$0.75 per serving - ****Calories: \~**380 kcal per serving - ****Source of:** Fibre, Protein, Iron, Vitamin A, B9, C, K ### Ingredients - 300g (1½ cups) dried cannellini beans, soaked overnight, or 800g (28 oz) canned (about 3-4 cans) - 300g (10 oz) cavolo nero or kale, tough stems removed, leaves shredded - 400g (14 oz) tin chopped tomatoes - 2 carrots, diced - 2 celery stalks, diced - 1 large onion, chopped - 3 garlic cloves, minced - 300g (10 oz) stale country bread, torn into chunks - 100ml (scant ½ cup) extra-virgin olive oil - 1.5 litres (6 cups) vegetable stock - 2 sprigs fresh rosemary and thyme - Parmesan rind (optional) ### Instructions 1. If using dried beans, drain and rinse them. Place in a pot with fresh water, bring to a boil, then simmer for 45–60 minutes until tender. 2. Drain, reserving some cooking liquid. Mash about half the beans with a fork; this helps thicken the soup naturally. 3. Heat the extra-virgin olive oil in a large, heavy pot over medium heat. Add the onion, carrots, and celery, cooking gently for 10 minutes until softened. Then add the garlic and cook for another minute. 4. Add the tomatoes and cook for 5 minutes, breaking them down with a wooden spoon. Stir in the beans (both whole and mashed), stock, rosemary, thyme, and Parmesan rind (optional). Bring to a boil, then reduce the heat and simmer gently for 30 minutes. 5. Add the shredded cavolo nero and cook for another 15–20 minutes until the greens are completely tender. Traditional ribollita should be well-cooked. The vegetables should melt into the broth. 6. Remove the herb sprigs and Parmesan rind. Stir in the torn bread, pushing it down into the liquid and let it sit for 10 minutes, allowing the bread to absorb the broth and soften. The soup will thicken. You can add more stock if you prefer it soupier, though authentic ribollita should barely hold its shape when you ladle it out. 7. For the best flavour, let the ribollita cool completely, then refrigerate overnight. The next day, reheat it gently. This traditional "reboiling" gives the dish its name and allows the flavours to deepen. 8. Add a splash of water or stock if needed to loosen it. Serve in wide bowls with a generous drizzle of extra-virgin olive oil, with some black pepper and grated parmesan (optional). --- ## 2\. Briam Briam (pronounced bree-am) is the Greek version of ratatouille (but with potatoes). It’s a rustic oven-baked mix of summer vegetables that typifies the [Mediterranean diet's](https://www.alphabetguides.com/tag/mediterraneandiet/) simple, seasonal, nutritious style of cooking. It comes from the tavernas and home kitchens across Greece. It's a dish that turns humble ingredients into something great through slow roasting and generous amounts of extra-virgin olive oil. You'll get some vitamin C and potassium from the potatoes, beta-carotene and vitamin A from the peppers, lycopene from the tomatoes, and lots of dietary fibre. The extra-virgin olive oil provides monounsaturated fats that help absorb fat-soluble vitamins while delivering its own dose of vitamin E and polyphenols. Serve it warm or at room temperature with crusty bread and crumbled feta. recipe information - ****Serves:** 6 - ****Time:** 1.5 hours - ****Cost:** \~$0.75 per serving - ****Calories: \~**280 kcal per serving - ****Source of:** Potassium, Fibre, Vitamin A, C, E ### Ingredients - 3 medium potatoes, sliced - 2 medium zucchini, sliced - 2 red bell peppers, cut into strips - 1 large aubergine, sliced - 4 ripe tomatoes, sliced - 1 large onion, thinly sliced - 3 garlic cloves, minced - 150ml (⅔ cup) extra virgin olive oil - 2 tablespoons tomato paste - 1 tsp dried oregano ### Instructions 1. Preheat your oven to 180°C (350°F). Ideally, cooking in a large, shallow baking dish, the vegetables should fit in a relatively snug single layer for even cooking. 2. In a large bowl, combine all the sliced vegetables, onion, and garlic. Add the olive oil, tomato paste, oregano, and season with salt and pepper. Mix well, ensuring everything is coated with the oil and seasonings. 3. Arrange the vegetables in the baking dish in a slightly overlapping pattern. It doesn’t have to be perfect, but it does have to be laid evenly so it cooks evenly. Pour any remaining oil mixture from the bowl over the top. 4. Add 120ml (½ cup) water to the dish, cover tightly with foil or a lid, and bake for about 1 hour, until the vegetables are tender but still hold their shape. 5. Remove the foil and bake for another 30–40 minutes until the vegetables are golden and slightly caramelised at the edges. If the dish looks dry, add a splash of water. 6. Let it rest for 10 minutes before serving. Scatter with some fresh herbs and drizzle with some extra olive oil if you want. It tastes better when made a day or two ahead of eating. --- ## 3\. Lentil Stew Umbrian lentil stew is the heart of Italy in a bowl. It’s an earthy, warming dish from the green hills where Italy's finest lentils grow. The small, prized lentils from Castelluccio di Norcia have fed Umbrians for centuries. Their delicate skins and rich flavour make them ideal for a stew. Unlike many legume dishes, these lentils need no soaking and cook relatively quickly, making this an easy weeknight meal. The lentils provide [high-quality plant protein](https://www.alphabetguides.com/plant-based-diet-meal-plan/), fibre, iron, and folate. Carrots and celery have vitamins, fibre and antioxidants. This humble stew captures the [Mediterranean diet's](https://www.alphabetguides.com/mediterranean-diet-guide/) emphasis on legumes as a cheap, [high-quality protein source](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/). Serve with crusty bread, a drizzle of extra-virgin olive oil, and perhaps some grated Pecorino. recipe information - ****Serves:** 4 - ****Time:** 1 hour minutes - ****Cost:** \~$0.75 per serving - ****Calories: \~**340 kcal per serving - ****Source of:** Protein, Fibre, Iron, Magnesium, Vitamin A, C, B9 ### Ingredients - 300g (1½ cups) dried brown or green lentils, rinsed - 400g (14 oz) tin chopped tomatoes - 2 carrots, finely diced - 2 celery stalks, finely diced - 1 onion, finely chopped - 3 garlic cloves, minced - 100ml (scant ½ cup) extra-virgin olive oil - 2 bay leaves - 2 sprigs fresh rosemary - 1 litre (4 cups) vegetable stock or water - Red wine vinegar, for serving (optional) ### Instructions 1. Heat the olive oil in a large, heavy pot over medium heat. Add the onion, carrots, and celery. Cook gently for 10 minutes, stirring occasionally, until the vegetables are softened but not browned. 2. Add the garlic and cook for 1 minute until fragrant. Stir in the tomatoes and cook for 5 minutes, breaking them down with a wooden spoon. The tomatoes should lose their raw flavour and begin mixing with the rest of the vegetables. 3. Add the lentils, bay leaves, and rosemary. Stir to coat the lentils in the tomato sauce, then add the stock. Generously season with salt and pepper. Bring to a boil, then reduce the heat to low and simmer gently. 4. Cook uncovered for 30–40 minutes, stirring occasionally, until the lentils are tender but still hold their shape. The cooking time varies depending on the age of the lentils and the type (older lentils take longer). The stew should be thick and porridge-like, not soupy. It should have just enough liquid to keep everything moist. Add more stock or water if it's a bit dry. 5. Remove the bay leaves and rosemary sprigs. Taste and adjust seasoning—the stew often needs more salt and pepper than you expect. You can mash some of the lentils against the side of the pot and stir them into the rest of the stew if you want a creamier texture. 6. Let the stew rest off the heat for 10 minutes; this allows it to thicken further and the flavours to settle. Like many legume dishes, it improves overnight and tastes even better the next day after the flavours have married. 7. Serve in wide bowls with a generous drizzle of extra-virgin olive oil and (optionally) a few drops of red wine vinegar. ![A bowl of lentil stew.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1664339031004-9cfdf88b8017.jpeg) --- ## 4\. Minestrone Soup Minestrone is Italy's most celebrated vegetable soup. It’s a hearty, ever-changing recipe that reflects whatever is available in the garden. From Milan to Sicily, every region and every household has its own version; united only by what’s available at the time: beans, vegetables, pasta, or rice. The beans provide [plant protein](https://www.alphabetguides.com/plant-based-protein/), fibre, and folate, while the varied vegetables deliver vitamins, minerals, and antioxidants. The small amount of pasta or rice adds carbohydrates, making this a complete meal by itself. Serve minestrone with crusty bread and a drizzle of extra-virgin olive oil, perhaps some grated Parmesan. recipe information - ****Serves:** 6 - ****Time:** 1.5 hours - ****Cost:** \~$0.75 per serving - ****Calories: \~**280 kcal per serving - ****Source of:** Protein, Fibre, Iron, Vitamin A, C, B9, K _This post is for subscribers only._ ### 5 Ways to Fix the Western Diet URL: https://www.alphabetguides.com/fix-the-western-diet/ Last updated: 2026-10-05T08:09:05.000Z Across the "West", life expectancy and healthy life expectancy are stalling, and in some cases getting worse. A lot of this has been attributed to the [Western diet](https://www.alphabetguides.com/western-diet/), which is the most common eating pattern of the people in North America, Europe and Australia. It is also increasing in urban areas all around the world.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/39085420/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/15699220/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/37375654/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/35134067/?ref=alphabetguides.com) The Western diet is based on [ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/), red meat and processed meats, refined grains, sugars, unhealthy fats, alcohol and sugary drinks. It has been linked to several health conditions: all the most common ones and all the bigger killers (i.e., cardiometabolic diseases, obesity, metabolic syndrome, dementias, gut problems, cancer and poor mental health).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/39085420/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/15699220/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/37375654/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/35134067/?ref=alphabetguides.com) The modern iteration of the Western diet is probably one of today’s most significant challenges for public health. But it [wasn't](https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/) always like this. In fact, we think it is one of the easiest (and cheapest) things to fix. ## Diagnosing the nutritional problem Although there is no standard Western diet to analyse, studies have identified several common nutrient "gaps" and "excesses" in people from Western countries. They are: - **Too much**: [ultra-processed food](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/), calories, dietary fat, saturated fat, sodium, added sugar, refined grains and animal foods. - **Too little**: dietary fibre, vitamin D, omega-3 fatty acids, magnesium, calcium, potassium, [fruit and vegetables](https://www.alphabetguides.com/tag/plant-based/). Also, iron and folate for women. Sources: [\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3328127/?ref=alphabetguides.com)[\[6\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8713704/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/30954305/?ref=alphabetguides.com)[\[8\]](https://pubmed.ncbi.nlm.nih.gov/26962035/?ref=alphabetguides.com)[\[9\]](https://www.gov.uk/government/statistics/national-diet-and-nutrition-survey-2019-to-2023/national-diet-and-nutrition-survey-2019-to-2023-report?ref=alphabetguides.com)[\[10\]](https://www.cdc.gov/nutrition-report/index.html?ref=alphabetguides.com)[\[11\]](https://www.abs.gov.au/statistics/health/food-and-nutrition/usual-nutrient-intakes/latest-release?ref=alphabetguides.com)[\[12\]](https://www.canada.ca/content/dam/hc-sc/migration/hc-sc/fn-an/alt%5Fformats/pdf/surveill/nutrition/commun/art-nutr-adult-eng.pdf?ref=alphabetguides.com) ## How to fix the problems with the Western diet The Western countries aren't short of health organisations, government health interventions, dietary advice, top scientists, nutritionists or public communication channels. So, what's gone wrong? It's really a trillion-dollar question; once you add the upfront health costs, welfare costs, the life years, healthy life years, and all working life years lost across the West. We believe that a significant portion of the problem lies in the fact that most advice available is overly complicated. Every month, there are new headlines, position statements, guidelines, food labelling systems, recommendations, reference values, reference intakes, plates and pyramids. Add to this the mixed messaging: track your calories, macros, micros, superfoods, eat your 5 a day, eliminate [sugar](https://www.alphabetguides.com/reduce-sugar-intake/), eliminate meat, eliminate eggs, eliminate [carbs](https://www.alphabetguides.com/keto-diet/), eliminate [fat](https://www.alphabetguides.com/low-fat-diet/), eliminate processed food, eliminate cooked food, eliminate gluten, and eliminate dairy; it goes on and on. It is all too much, and it has all failed. Look at the real-world results. People are busy, people run out of money, people hate cooking, people like tasty food, and people tend to slide back into old habits. The ultra-processed food companies get it; a lot (but not all!) of the health scientists, nutritionists and politicians don't. It doesn't matter how sophisticated, accurate, or good the marketing is; if the recommendations aren't followed, they have zero use. Look at the history of the 5 a day campaign. After 40 years of pushing it, millions spent on marketing, and 90% of adults are aware of the advice. However, 83% of adults and 91% of children still don't follow it. Fruit and vegetable intake is at an all-time low. The scientists have now also changed their minds, and the advice is considered to be out of date.[\[9\]](https://www.gov.uk/government/statistics/national-diet-and-nutrition-survey-2019-to-2023/national-diet-and-nutrition-survey-2019-to-2023-report?ref=alphabetguides.com) Turns out that you actually need to consume [more](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/) than your 5 a day. What a waste of time and money.[\[13\]](https://pubmed.ncbi.nlm.nih.gov/24687909/?ref=alphabetguides.com) ### Methods: How we arrived at our recommendations To solve this problem, we designed a different approach. 1. Identify the dietary gaps and excess consumption for both individual nutrients and food groups. 2. Screened potential solutions through a "return on intervention" ("ROI") filter, based on. 1. Nutrition: Does this food solve a specific nutritional problem with the Western diet? 2. Friction: Is it cheap, accessible, edible, sustainable, has a long shelf life, and quick and easy to eat? 3. "Forward" selection: What are the *additional* benefits of the recommendation, over and above the other ones? Using this, we have come up with 5 recommendations, which are ordered by "ROI", from highest to lowest (most nutrition for least friction first). So, start with recommendation 1 and work towards doing all 5 if you can. If you can add these five simple habits to your weekly routine, you can bring your diet close to the Western equivalent of a gold-standard [Mediterranean-style diet](https://www.alphabetguides.com/tag/mediterraneandiet/). --- ## Recommendations ## 1\. Eat oats for breakfast, as often as possible Traditionally, most people in Western countries ate oats for breakfast on most days. This was before sugary breakfast cereals, pain au chocolat, doughnuts and coffee, industrially produced white bread, and toasters became kitchen or take-out staples. It doesn't matter whether the oats are hot, cold, microwaved, overnight, rolled, steel-cut, or diamond cut. Just eat them for breakfast every day, or as often as you can. They take minutes to prepare, whether you're cooking for 1 or 10 people, and they cost pennies per serving. We have rated this at number one because breakfast is the easiest meal of the day to "automate" and make into a habit. Nutritionally speaking, Western breakfasts are also one of the worst offenders: they're usually ultra-processed, sugary and calorie-dense. Oats contain a lot of soluble *fibre.* And a lot of a unique type of soluble fibre called "beta-glucan", which lowers bad LDL cholesterol. When you eat oats, they form a gel-like mass in your digestive system, slowing down stomach emptying and absorption into your bloodstream. This means flatter blood sugar or insulin spikes even if you eat them with other carbohydrates or sugars.[\[14\]](https://pubmed.ncbi.nlm.nih.gov/25411276/?ref=alphabetguides.com)[\[15\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8563417/?ref=alphabetguides.com) Oats have also been linked to good gut health, immunity, gluten-free status, and have anti-cancer and anti-inflammatory properties. They're one of the healthiest carbohydrates around.[\[16\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8625765/?ref=alphabetguides.com) [The Health Benefits of Eating Oats for BreakfastOats are popular for a reason. In addition to being cheap, sustainable and hardy, they have several well-known health benefits.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-94e85b74-d0fd-467f-89d2-f69b4d749b9f.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1565848920056-906a21da8c70-bb33215d-459c-41b7-b9fb-d2fd883c5466.jpeg)](https://www.alphabetguides.com/oats-health-benefits/) ## 2\. Add 1 can of legumes to your weekly shop Buy exactly one standard can (400g / 15 oz) of chickpeas, lentils, black beans, kidney beans or whatever local legumes are available *every* week. You do not need to cook them from scratch. Simply open the tin, rinse them in a colander, and eat them throughout the week. Put them into bolognese sauce, taco meat or chilli. Add them to soups, stews or salads. Mash them into a puree (with other flavourings) and spread them on bread or toast. They are number 2 on our list, as they address several nutritional deficiencies in the Western diet. They contain a lot of fibre, magnesium, potassium, protein, lysine, low-GI carbohydrate, folate and non-heme iron. Because of the last two nutrients, they may even be ranked number 1 for women and girls. They are probably the most nutritious food per dollar on the planet. They are also great for the environment (natural fertilisers), so eating more of them will increase food security in your region.[\[17\]](https://pubmed.ncbi.nlm.nih.gov/34471332/?ref=alphabetguides.com) One can provides around 3 servings (\~80 g serving) of legumes for pennies, which is around what you should be eating (3 servings a week). Intake of legumes has been associated with prevention and treatment of many chronic diseases, including type 2 diabetes, cardiovascular diseases, obesity, inflammatory diseases and cancer.[\[18\]](https://www.sciencedirect.com/science/article/abs/pii/S2214799317300085?via%3Dihub&ref=alphabetguides.com) Adding them to your diet can lower your cholesterol, LDL levels and triglyceride levels, blood sugar and insulin levels, blood pressure, and body weight. They're also great for gut health and gut function, containing resistant starch and soluble fibre.[\[19\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4608274/?ref=alphabetguides.com) [Health Benefits of Legumes: Just One Can a WeekAdding just one simple can of legumes a week to your weekly shop can transform your heart and gut health, your wallet, and the planet.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-1dc1e65e-cdb3-441e-b7a6-6067b3807a40.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1599579085809-4edbc35cee01-65a269c2-1b8b-4b88-9c2c-175360ec3214.jpg)](https://www.alphabetguides.com/legumes-and-health/) _This post is for subscribers only._ ### Adapting the Mediterranean Diet for the Western World URL: https://www.alphabetguides.com/adapted-mediterranean-diet/ Last updated: 2026-09-01T13:31:00.000Z The modern iteration of the [Western diet](https://www.alphabetguides.com/western-diet/) is a health catastrophe unfolding. It is making us sick. It is now mostly made up of ultra-processed foods, refined sugars, artificial sweeteners, refined fats, and processed meat. It's low fibre, low nutrition and now has blatantly obvious poor health outcomes.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/41270766/?ref=alphabetguides.com) These diets are eaten across most of the developed world, particularly the Anglo-world (i.e., Western Europe, North America, Australasia), but they are also becoming more popular in the developed world as well. And they have been linked to several severe, widespread [diseases and poor health outcomes](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/), like: - Cardiovascular diseases - Obesity and metabolic syndrome - Several different cancers - Type 2 diabetes - Poor mental health - Lower life expectancy and healthy life expectancy These outcomes are direct consequences of a dietary shift. This is not a small problem. It is probably the biggest (but most easily fixed) public health issue Anglo-Western (and many other) countries face. Sources: [\[1\]](https://pubmed.ncbi.nlm.nih.gov/41270766/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/38418082/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31105044/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/37087831/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/31142457/?ref=alphabetguides.com) ## What is the answer to the Modern Western diet? In response, public health organisations, scientists and nutritionists have turned to the Mediterranean diet. It is the most-studied diet in the world, with decades of high-quality research behind it. It's [cheap](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/). It has been tried and tested for centuries. It has unparalleled health outcomes.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/34423871/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/28488692/?ref=alphabetguides.com) Even in our own analyses, it features at the top of nearly every list we've compiled: [heart](https://www.alphabetguides.com/heart-health-diets/) health, [brain](https://www.alphabetguides.com/brain-health-diets/) health, healthy [body weights](https://www.alphabetguides.com/fat-loss-diets/), and good [general health](https://www.alphabetguides.com/healthiest-diets/). However, despite its benefits, it has still not been widely adopted. In fact, most people in the West wouldn't have a clue what the Mediterranean diet actually is. When you first hear about the diet, you might picture olive groves in Tuscany, vineyards, figs, tomatoes, wild-caught sea bream from the Aegean, and a shopping basket that costs a small fortune. You may assume that eating "Mediterranean" means buying Mediterranean. It doesn't. The health benefits of this diet were never about latitude, sunshine, or where your nearest coastline is. It comes from its content, a specific combination of healthy fats, high fibre, and lots of [phytonutrients](https://www.alphabetguides.com/tag/plant-based/). Your body cannot tell whether a molecule of omega-3 comes from an olive grove in Seville or a rapeseed field in Yorkshire. However, for your average Western shopper, following the diet may be unsustainable. Premium extra virgin olive oil, imported [out-of-season](https://www.alphabetguides.com/eat-the-seasons-the-seasonality-rule/) fruits and vegetables, and wild-foraged bitter greens are out of reach for most people: financially, environmentally and culinarily. ## Can you adapt the Mediterranean diet? There is proof-of-concept that the Mediterranean diet can be adapted at a national scale. The "[New Nordic Diet](https://www.alphabetguides.com/nordic-diet/)" was created by Nordic nutritionists, scientists and chefs to try to improve the health outcomes of their people. This was based on the Mediterranean diet, but adapted to the Nordic regions using home-grown Northern European substitute ingredients. - [Rapeseed (or canola) oil](https://www.alphabetguides.com/canola-vs-olive-oil/) instead of olive oil - Root vegetables and berries instead of Mediterranean produce - Cold-water North Sea fish instead of Mediterranean seafood Nordic people who followed the new Nordic diet for 6-months lost weight (around 3kg) and lowered their blood pressure (by around 3-5 mmHg). They copied the Mediterranean diet *formula,* but not the exact ingredients, and they got comparable health benefits.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/24257725/?ref=alphabetguides.com) We aim to do the same in this article for the Western diet. The same proven health benefits, but a cheaper, local, seasonal, and sustainable variant. This version of the diet rests on three core pillars: 1. **Nutritional:** It matches or exceeds the exact nutritional and biochemical benefits of Mediterranean foods and food groups. 2. **Sustainable:** Aim to minimise food miles, food waste, pollution, and environmental footprint by prioritising foods that are native or efficiently grown. 3. **Economical:** Aim to lower the upfront $/£ cost, waste, and benefit the local economy by prioritising abundant, local, and shelf-stable staples. --- ## Swap 1: Olive oil for cold-pressed rapeseed oil _This post is for subscribers only._ ### 6 Healthy Vegan Mediterranean Diet Recipes URL: https://www.alphabetguides.com/vegan-mediterranean/ Last updated: 2026-09-18T11:32:27.000Z ## 1\. Hummus Hummus is the Levantine dip that has conquered the Mediterranean and beyond. At its best, it should be a silky purée of chickpeas, tahini, lemon, and garlic that's been sustaining populations for centuries. While its exact origins spark debate across the Middle East, there's no dispute about its nutrition or taste. This protein-rich spread exemplifies the [Mediterranean diet's](https://www.alphabetguides.com/tag/mediterraneandiet/) reliance on legumes as a cornerstone of healthy eating. Chickpeas provide [plant protein](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/), fibre, and folate, while tahini adds calcium, iron, and healthy fats. The garlic is thought to have immune-supporting compounds. Serve hummus as part of a meze spread with warm whole wheat flat bread, fresh veg, and olives. Or use it as a nutritious sandwich spread or dip. recipe information - ****Serves:** 6 - ****Time:** 50 minutes - ****Cost:** \~$0.75 per serving - ****Calories:** 180 kcal per serving - ****Source of:** Fibre, Iron, Copper, Vitamin B9 ### Ingredients - 400g (14 oz) tin chickpeas, or 200g (1 cup) dried chickpeas, cooked - 80g (⅓ cup) tahini, well stirred - 2 garlic cloves, crushed - Juice of 1–2 lemons - ½ teaspoon ground cumin (optional) - 60–80ml (¼–⅓ cup) ice-cold water - 60ml (¼ cup) extra-virgin olive oil - Sweet paprika and fresh parsley, for garnish ### Instructions 1. Drain cooked chickpeas but reserve the nutritious liquid (called “aquafaba”). If you have time, and it's for a special occasion, you can remove the chickpea skins by putting the chickpeas into a bowl of water and rubbing them between your hands; the skins float to the surface. This step is optional but improves the texture of the hummus. 2. In a food processor, blend the tahini, garlic, lemon juice, cumin, and a generous pinch of salt for 1 min until smooth and lightened in colour. This is the tahini base that is done first, which prevents the hummus from being grainy. 3. Add the chickpeas and process for 2–3 minutes, scraping down the sides occasionally. The mixture will seem thick and paste-like at first—this is normal. With the motor running, slowly drizzle in the iced water (or fridge-cold aquafaba) and extra-virgin olive oil. The hummus should transform into a smooth, light consistency. Add more water if needed; you want it creamy but to hold its shape. 4. Taste and adjust seasoning, adding more lemon juice or salt if needed. To serve, spread the hummus on a shallow plate using the back of a spoon to create swirls and valleys. These aren't just decorative—they hold pools of extra-virgin olive oil. Drizzle generously with extra-virgin olive oil, then dust with paprika and scatter with fresh parsley. You can add more herbs, spices or other flavours at this stage if you want something different. 5. Hummus tastes best at room temperature and keeps refrigerated for 5 days. Let it sit out for 20 minutes before serving, and refresh with a splash of water if it's thickened. --- ## 2\. Zucchini al pesto Zucchini al pesto is a variation of a light, elegant dish from Liguria, the Italian region that gave the world pesto Genovese. This preparation transforms raw or lightly cooked zucchini ribbons into delicate “noodles” dressed with the region's famous basil sauce. It represents the Mediterranean approach to vegetables as the centrepiece rather than an accompaniment. The zucchini provides fibre, vitamins C and K, and beneficial antioxidants, including lutein for eye health. Fresh basil contributes vitamin K and anti-inflammatory compounds, while the pine nuts add [protein](https://www.alphabetguides.com/plant-based-diet-meal-plan/), magnesium, and [heart-healthy](https://www.alphabetguides.com/tag/heart-health/) fats. Parmesan (optional) delivers calcium and umami flavouring, and the generous olive oil provides monounsaturated fats that help absorb fat-soluble vitamins. Serve as a light main course or elegant side dish alongside grilled fish or chicken. recipe information - ****Serves:** 4 - ****Time:** 20 minutes - ****Cost:** \~$1 per serving - ****Calories:** 320 kcal per serving - ****Source of:** Protein, Calcium, Magnesium, Vitamin A, C, K ### Ingredients - 80g (3 cups packed) fresh basil leaves - 50g (⅓ cup) pine nuts, lightly toasted - 2 garlic cloves, roughly chopped - 60g (⅔ cup) freshly grated Parmesan cheese (optional) - 150ml (⅔ cup) extra-virgin olive oil - Juice of ½ lemon - 6 medium zucchini (about 800g/1¾ lb) - Extra Parmesan shavings for serving (optional) - Toasted pine nuts for garnish ### Instructions 1. Make the pesto first. In a food processor or pestle and mortar, purée the pine nuts, garlic, and a pinch of salt. Add the basil leaves; they should be completely dry, or the pesto will be watery, and mix until broken down. Scrape down the sides and add the Parmesan until combined. 2. With the motor or pestle slowly moving, drizzle in the extra-virgin olive oil until it reaches a smooth, thick consistency. It should be creamy and spreadable, not dry or separated. Stir in the lemon juice, salt, and pepper to taste. The pesto can be made up to 3 days ahead; store with a thin layer of EVOO on top to prevent oxidation. 3. Using a spiralizer, julienne peeler, a knife or mandoline, cut the zucchini into long, thin noodles. Alternatively, use a vegetable peeler to create wide ribbons. Leave the skin on for the colour contrast and nutrients, just trim the ends. 4. Place the zucchini noodles in a colander and toss with a generous pinch of salt. Let them sit for 10 minutes to draw out excess moisture. After 10 minutes, gently squeeze the noodles with your hands or press with paper towels to remove the released liquid. 5. For a raw preparation, simply toss the salted and drained zucchini noodles with the pesto in a large bowl. For a warmer dish, heat extra-virgin olive oil in a large pan over medium-high heat and sauté the zucchini noodles for just 2–3 minutes, tossing constantly, until barely tender but still bright green and crisp. Don't overcook or brown them, just heat through before adding the pesto. 6. Serve immediately on individual plates or a large platter, twirling the noodles into neat nests if desired. Garnish with fresh basil leaves and toasted pine nuts. Finish with a drizzle of extra-virgin olive oil and freshly cracked black pepper. This dish is best enjoyed immediately. --- ## 3\. Vegetable Couscous This dish celebrates the sun-drenched [vegetables](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/) of the Mediterranean: peppers, courgettes, aubergines, and tomatoes roasted until caramelised and sweet, then tossed with fluffy couscous and fresh herbs. This dish appears across North Africa and the Middle East, where couscous is a staple grain, particularly in Morocco, Tunisia, and Algeria. The [colourful vegetables](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/) provide vitamins A and C, fibre, and a spectrum of antioxidants, including lycopene and beta-carotene. The couscous also offers complex carbohydrates and some [protein](https://www.alphabetguides.com/plant-based-protein/). Serve warm or at room temperature as a main course or a side dish alongside grilled fish or chicken. recipe information - ****Serves:** 4 - ****Time:** 1 hour - ****Cost:** \~$0.75 per serving - ****Calories: \~**420 kcal per serving - ****Source of:** Protein, Fibre, Vitamin A, B6, B9, C, K ### Ingredients - 250g (1¼ cups) couscous - 300ml (1¼ cups) hot vegetable stock - 2 red bell peppers, cut into chunks - 2 courgettes, cut into chunks - 1 aubergine, cut into chunks - 1 red [onion](https://www.alphabetguides.com/3-healthiest-vegetables-around/), cut into wedges - 250g (9 oz) cherry tomatoes - 3 garlic cloves, unpeeled - 120ml (½ cup) extra-virgin olive oil - 1 pomegranate (optional) - 1 teaspoon ground cumin - 1 teaspoon smoked paprika - Large handful of fresh parsley, chopped - Large handful of fresh mint, chopped - Juice of 1 lemon - 50g (⅓ cup) toasted pine nuts or almonds ### Instructions 1. Preheat your oven to 220°C (425°F). In a large bowl, toss the vegetables with 80ml (⅓ cup) of the extra-virgin olive oil, the spices, salt, and plenty of black pepper. Spread the vegetables in a single layer across two large baking trays. Roast for 30–35 minutes, turning halfway through, until the vegetables are tender with charred edges and the tomatoes have burst. 2. While the vegetables roast, place the couscous in a large bowl with a pinch of salt. Pour the hot stock over it, stir once, then cover tightly with a plate or cling film. 3. Let it stand for 5 minutes, and the couscous will absorb all the liquid and become tender. Uncover the couscous and fluff it with a fork, breaking up any clumps. Drizzle with the remaining extra-virgin olive oil and half the lemon juice, and fluff again. 4. Remove the vegetables from the oven. Squeeze the roasted garlic cloves from their skins and mash them roughly with a fork. Stir this roasted garlic paste through the warm couscous. 5. Add the roasted vegetables to the couscous along with any pan juices. Then add most of the chopped herbs and the remaining lemon juice, tossing gently to combine. The vegetables should be distributed throughout, rather than sitting on top. 6. Taste and adjust seasoning; roasted vegetables often need more salt than you expect. Transfer to a serving platter, scatter with the toasted nuts, pomegranate (optional) and remaining herbs, and finish with a final drizzle of extra-virgin olive oil. 7. Serve warm or at room temperature—the flavours develop beautifully as it sits. This dish keeps well refrigerated for 3 days and can be enjoyed cold as a satisfying salad. ![Vegetable couscous on a ceramic plate.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1596723427394-4bc6d407dee1-1.jpeg) --- ## 4\. Fig Jam Time for something sweet! Fig jam is a treasured preserve across the Mediterranean, where ancient fig trees have fed communities for millennia. From Provence to Andalusia to the Greek islands, this simple “jam” or “conserve” captures summer's abundance to brighten winter tables. Unlike commercial jams loaded with refined sugar, the Mediterranean approach relies on the fruit's natural sweetness, perhaps enhanced with just a bit of honey. This method creates a darker, more complex preserve that tastes of the fruit itself rather than sugar. Figs are remarkably nutritious, providing fibre, potassium, calcium, antioxidants, and iron, along with natural sugars that provide energy. The pectin in figs helps the jam set naturally without the need for any additives. Spread this jam on morning toast, pair it with aged cheese, or swirl it into yoghurt for an authentic taste of the Mediterranean. recipe information - ****Serves:** 20+ - ****Time:** 50 minutes - ****Cost:** \~$0.15 per serving - ****Calories:** 45 kcal per serving - ****Source of:** Potassium ### Ingredients - 1 kg (2¼ lb) ripe fresh figs, stems removed and quartered - 2–3 tbsp honey (optional) - Juice of 1 lemon - 1 cinnamon stick (optional) - 2–3 tablespoons water ### Instructions 1. Choose ripe, soft figs that yield to gentle pressure. They should be fragrant and deeply coloured. Black Mission, Brown Turkey, or green Kadota varieties all work fine. Wash gently and quarter them, leaving the skin on for texture, colour, and nutrients. 2. Place the figs in a wide, heavy-bottomed pot with the lemon juice, water, and cinnamon stick (optional). The lemon juice adds brightness and helps preserve the colour, shelf-life and provides more natural pectin (from the figs). Bring to a gentle simmer over medium heat, stirring occasionally. 3. Let the mixture bubble gently for 30–40 min, stirring regularly to prevent sticking. The figs will break down naturally, releasing their juices and pectin. Use a wooden spoon to mash some of the figs against the side of the pot if you prefer a smoother texture, or leave it chunky for a more rustic texture. 4. As it cooks, it will thicken and darken to a rich mahogany colour. Test for doneness by placing a spoonful on a cold plate—after a minute, it should wrinkle when pushed with your finger and hold its shape rather than running. If it's too liquid, continue cooking for another 5–10 min. Taste and stir in honey only if the figs aren't sweet enough, though most ripe figs need nothing added. 5. Remove the cinnamon stick and pour the hot jam into clean, sterilised jars, leaving 1cm (½ inch) headspace. Wipe the rims clean and seal immediately. The jam will continue to thicken as it cools to a spreadable consistency. 6. Store sealed jars in a cool, dark place for up to 6 months. Once opened, refrigerate and use within 3 weeks. The jam's flavour deepens after a few days as the flavours meld and mature. --- ## 5\. Olive Tapenade Tapenade is a classic Provençal olive spread. It’s a bold condiment from the rocky coast, where olive trees and capers thrive in the Mediterranean sun. Named after tapeno, the Provençal word for capers, this ancient paste has been feeding the region since antiquity. What makes tapenade Mediterranean is its celebration of preserved ingredients: olives, capers, and anchovies, all staples in the [Mediterranean pantry](https://www.alphabetguides.com/7-pantry-essentials-for-the-mediterranean-diet/). The olives provide heart-healthy monounsaturated fats, polyphenols, and vitamin E, while capers contribute quercetin, a powerful antioxidant with anti-inflammatory properties. Anchovies (optional) add omega-3 fatty acids and umami flavouring. This intensely flavoured spread transforms [simple meals](https://www.alphabetguides.com/mediterranean-diet-meal-plan/): smear it on grilled fish, toss with pasta, spread on flatbread, or use as a dip for raw vegetables. recipe information - ****Serves:** 8 - ****Time:** 10 minutes - ****Cost:** \~$0.25 per serving - ****Calories:** 100 kcal per serving - ****Source of:** Fibre, Vitamin E _This post is for subscribers only._ ### Why the Mediterranean Diet is the Gold Standard for Health URL: https://www.alphabetguides.com/health-mediterranean-diet/ Last updated: 2026-09-21T10:02:29.000Z summary - The Mediterranean diet is "nutrient-dense", providing thousands of healthy nutrients for relatively few calories. - Quality matters: food, time, lifestyle, rest, movement, dining, and socialising are all high-quality, and all contribute to its health benefits. - The diet is based on minimally processed plant foods. These not only improve health by themselves, but they also crowd out other (bad) foods. The Mediterranean diet's transition from a [simple](https://www.alphabetguides.com/mediterranean-one-pot/) traditional eating pattern to a scientific dietary “intervention” is mainly thanks to an American physiologist called Ancel Keys. It was his research in the mid-20th century that was the first to formally report its unparalleled [health benefits](https://www.alphabetguides.com/tag/health/). It has since transformed the scientific community's view of the role of diet in disease. Keys’ “Seven Countries Study” from the 1950s was one of the first studies looking at the role that diet and lifestyle had on cardiovascular disease across different people from different places in the world. The study looked at health data from seven countries: the US, northern, southern, and eastern Europe and Japan.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/3776973/?ref=alphabetguides.com) Keys found that people in Southern Europe (specifically Crete and southern Italy), despite being poorer with modest resources, experienced much lower rates of disease and longer life expectancies. He then noticed their unique dietary patterns and made the link: vegetables, fruits, legumes, and olive oil, with moderate fish and minimal amounts of meat, correlated with good [cardiovascular health](https://www.alphabetguides.com/tag/heart-health/). This challenged the view that economic development, healthcare, medical innovations and money were the drivers of good health. Keys hypothesised that dietary fats played an important role, specifically the type of fat that's maybe just as important as the amount of fat that's eaten. His research showed that saturated fats from meat and dairy raised cholesterol levels, while monounsaturated fats from [olive oil](https://www.alphabetguides.com/superfood-olive-oil/) did not.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/7754982/?ref=alphabetguides.com) This finding fundamentally reshaped nutritional science. But Keys didn't merely observe; he lived the [Mediterranean lifestyle](https://www.alphabetguides.com/mediterranean-culture/) himself. He and his wife moved to live in Pioppi, a small Italian village, where they adopted the local diet and customs. His wife even wrote a book, “How to Eat Well and Stay Well the Mediterranean Way”. Keys himself remained remarkably healthy, living to 100 years old — a testament to practising what you preach. After more research confirmed the benefits of the [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/), it has now been "formalised" by health institutions emphasising plant foods, olive oil, moderate fish intake and limited red meat and processed food consumption. Since then, hundreds of independent studies ranging from large-scale observational studies to high-quality randomised controlled trials, from around the world, have reported positive health effects for the diet, confirming Keys’ original observations.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/30817261/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/24476641/?ref=alphabetguides.com) Today, many major health organisations worldwide and numerous national dietary guidelines recommend a Mediterranean-style diet. This is a remarkable transformation: from traditional peasant food to globally recognised evidence-based dietary intervention. This is thanks largely to Keys' pioneering vision and scientific rigour. Here are the four pillars on which it is built.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/7754995/?ref=alphabetguides.com) #### Who Was Ancel Keys? Ancel Keys was the first scientist to link the Mediterranean’s low disease rates and longer life expectancies to their diet. Since then, decades of research have supported this, and it now shapes nutritional science and health policy around the world. ## On this page: 1. High Nutrient Density 2. High Food Quality 3. Minimally Processed Food 4. Healthy Protein Sources --- ## #1\. High Nutrient Density ****Summary:** The Mediterranean diet provides higher amounts of nutrients without too many extra calories. These help protect against many diseases and promote healthy ageing. Nutrient density is the amount of essential vitamins, minerals, and other beneficial compounds a food has relative to the amount of calories. This is what distinguishes the Mediterranean diet from typical unhealthy [Western diets](https://www.alphabetguides.com/western-diet/). The higher the nutrient density of the diet, the healthier it is. Compared to most diets, the Mediterranean diet provides greater amounts of folate, vitamins C and E, magnesium, potassium, and antioxidants per calorie.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/16210699/?ref=alphabetguides.com) Its base of [colourful](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/) vegetables, fruits, legumes, whole grains, nuts, and extra virgin olive oil creates a nutritional profile that meets or exceeds requirements for virtually all essential nutrients. It does this while naturally limiting empty calories from processed junk foods and added sugars. Nutrient density becomes more important as we age when calorie intake decreases, and nutrient requirements increase. Older adults face the challenge of meeting nutritional needs with fewer calories, making every food choice even more important. The Mediterranean diet’s emphasis on nutrient-dense whole foods can help prevent the micronutrient deficiencies common in ageing populations (like vitamin D, B9, B12, calcium, magnesium), without requiring excessive food intake. Older adults who follow the Mediterranean diet tend to have better [nutrition](https://www.alphabetguides.com/tag/nutrition/) compared to people consuming typical Western diets.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/36839385/?ref=alphabetguides.com) ### What about supplements? While supplements can be used to fill nutrient deficiencies, whole foods that contain several different nutrients can work together and deliver themselves into the body better than any individual supplement can. This is known as the “[food matrix effect](https://www.alphabetguides.com/food-matrix/)” — different nutrients working together as nature packaged them. For example, lycopene from tomatoes is better absorbed when consumed with olive oil. Vitamin C from vegetables enhances iron absorption from [legumes](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/). The polyphenols in extra virgin olive oil work alongside vitamin E in nuts to provide antioxidant protection for your cells. The benefits of the Mediterranean diet extend beyond the basic vitamins and minerals. Like most [plant-based](https://www.alphabetguides.com/tag/plant-based/) diets, the Mediterranean diet is rich in “phytonutrients”: - Flavonoids from berries - Carotenoids from orange and red vegetables - Polyphenols from olive oil and herbs - Glucosinolates from cruciferous vegetables. These compounds have been shown to protect against disease and premature ageing. There are hundreds of different "phytonutrients" found in Mediterranean foods, which create a hugely complex “defence system” for your body — something supplements can’t replicate. If you want to maximise nutrient density by following the Mediterranean diet, choose minimally processed whole foods first. [Most of your plate](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/) should be filled with colourful non-starchy vegetables; different colours mean different phytonutrients. Choose whole grains over refined grains. Use antioxidant-rich extra virgin olive oil for cooking and finishing dishes. Prioritise lean, nutrient-dense proteins like fish, legumes, and nuts over processed meats. Herbs and spices can provide some additional nutrients along with flavour. --- ## #2\. Quality: Food & Other Things _This post is for subscribers only._ ### Eccentric Exercise For Muscle & Joint Health: Does it Work? URL: https://www.alphabetguides.com/eccentric-exercise-for-muscle-joint-health-does-it-work/ Last updated: 2026-10-02T14:21:42.000Z summary - Eccentric contractions involve muscle lengthening under tension and can generate greater forces than concentric (shortening) contractions. - This greater load creates unique adaptations leading to superior growth stimulus compared to concentric training. - Eccentric exercise training requires careful progression and longer recovery due to increased potential for muscle damage. When you think about [muscle-building exercise](https://www.alphabetguides.com/tag/muscle/), you might picture lifting heavy weights or performing explosive movements. But one of the most powerful and sometimes overlooked tools is "eccentric" exercise**.** This style of exercise emphasises the controlled *lengthening* of the muscles under tension. Whether you realise it or not, eccentric contractions occur in almost every workout and in everyday life, and it plays a crucial role in muscle adaptations. ## What is Eccentric Exercise? Eccentric [exercise](https://www.alphabetguides.com/tag/exercise/) specifically refers to a type of muscle contraction where the muscle *lengthens* while generating force. It is sometimes referred to as the “lowering” or “negative” phase of a lift. Think walking downstairs, running downhill or sitting down. This is the opposite of the “concentric” contraction, where the muscle *shortens.* Like walking upstairs, running uphill or getting up off the sofa. Whilst both concentric and eccentric contractions are essential for most [human movements](https://www.alphabetguides.com/why-walking-beats-running/), they are used together in everyday life. The eccentric contraction is particularly important for its unique effects on your muscles and on muscle growth. One defining characteristic of eccentric contractions is their ability to generate greater forces than concentric contractions. This means you can often resist heavier loads during the eccentric phase of the lift than you can concentrically. In other words, you can *lower* more weight than you can *lift*. Scientists think this may be a hard-wired safety mechanism to prevent serious muscle and joint injuries. However, it also makes eccentric training highly effective at creating tension in the muscle, which is a key driver of [growth](https://www.alphabetguides.com/back-to-basics-a-checklist-for-muscle-growth/).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/27638040/?ref=alphabetguides.com) --- ## Different Types of Muscle Contractions - **Eccentric contraction:** The muscle *lengthens* while producing force (e.g., lowering a weight). - **Concentric contraction:** Themuscle *shortens* while producing force (e.g., lifting a weight) - **Isotonic contraction:** The muscle moves while producing the *same* tension. This type of contraction is rarely done in natural human movements. - **Isoinertial contraction:** The muscle contracts against a fixed external load (e.g., barbell, dumbbell or suitcase) - **Isokinetic contraction:** The muscle contracts at a *constant speed*. It is usually used in a rehab setting, not in natural movements that you do daily. - **Isometric contraction:** The muscle produces force but *doesn’t move* (e.g., holding a weight or a barnacle stuck to a rock). - **Auxotonic contraction:** The muscle moves while changing its tension. This is most common in natural movements. --- ## What does eccentric training do? Studies have shown that eccentric training creates distinctive changes in the muscles compared to normal weightlifting exercise. During eccentric contractions, the individual muscle "fibres" experience higher tension and greater [physical damage](https://www.alphabetguides.com/doms/) at the cellular level (termed microdamage or microtrauma). This stimulates a greater growth response.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/28725197/?ref=alphabetguides.com) Beyond muscle growth, eccentric training is also effective at improving [muscle strength](https://www.alphabetguides.com/muscle-adaptation/) and tendon strength. This, this is why it's frequently used in rehabilitation programs for preventing or [recovering](https://www.alphabetguides.com/rest-and-body-composition/) from sports injuries.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/18981046/?ref=alphabetguides.com) ## Eccentric exercise: is it all upside? Not quite. Over-focusing on eccentric exercise can be a double-edged sword. If done incorrectly or you do too much too quickly, it can lead to injury or prolonged recovery times. While muscle soreness can be an indicator of an effective stimulus to grow, there *can* also be muscle pain with no or little growth. Too much eccentric exercise without proper progression may lead to injury or [training setbacks](https://www.alphabetguides.com/deload/), especially for novice lifters.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/31130877/?ref=alphabetguides.com) To use eccentric training safely, it’s essential to incorporate it thoughtfully into your training programme. [Progressive overload](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/) remains key. Gradually increasing the amount of eccentric exercise allows muscles and connective tissues to adapt without causing excessive damage. It's a balancing act. Eccentric exercise methods can vary. From deliberately slow “negative” repetitions (e.g., lowering a weight over 3–5 seconds with a fixed weight like a dumbbell or barbell) to special techniques and specialised machines, where the eccentric phase of the exercise uses heavier loads than the concentric phase. ## Eccentric training workouts & safety precautions In practical terms, you might incorporate eccentric training into your programme by emphasising the slower and more controlled lowering phase during different exercises. Another popular method is “negatives,” where the lift phase is assisted. For example, a training partner helps lift the weight, and the lifter controls only the lowering phase of the exercise. This allows you to safely exceed your normal strength limits, increasing mechanical tension and thus the [growth stimulus](https://www.alphabetguides.com/minimalist-muscle-growth/). Studies show that incorporating eccentric exercise in [resistance training programs ](https://www.alphabetguides.com/resistance-training-beginners/)(*not* rehab programs) can lead to greater muscle growth outcomes. But for growth, it needs to be heavy (probably above 100% concentric max). If you're lifting the *same* weight for the *same* time for the *same* number of sets, reps, and volume, it *doesn’t* seem to stimulate different amounts of growth, regardless of whether it is done concentrically or eccentrically.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/18981046/?ref=alphabetguides.com) It is also worth noting that eccentric exercise may need longer recovery, which may be prolonged with poor nutrition, rest, and recovery practices. It seems eccentric exercise can be a powerful part of an effective exercise training programme. However, it is not a panacea. Due to your muscles’ ability to generate higher forces during muscle lengthening, eccentric exercise can manipulate the extra mechanical stress, microtrauma, and muscle growth to its advantage. But it requires careful and considered execution to balance the "growth" stimulus with recovery and minimise injury risk: it is probably not advised for novice lifters. --- #### Sources 1.

Greek Salad Greek salad, or “Horiatiki” (hor-ee-AH-tik-ee), is the quintessential village-style salad found on taverna tables across Greece. The authentic version is just ripe summer vegetables at their peak, generous chunks of feta, and a simple dressing of extra-virgin olive oil and oregano. This salad embodies the Mediterranean principle that great food is made with great ingredients rather than complicated technique. In addition to the vitamins and antioxidants from the vegetables and the healthy fats from the extra-virgin olive oil, the feta provides extra calcium and [protein](https://www.alphabetguides.com/plant-based-diet-meal-plan/). Serve horiatiki as a side dish, light lunch, or in a meze alongside grilled fish and whole wheat flatbread. recipe information - ****Serves:** 4-6 - ****Time:** 50 minutes - ****Cost:** \~$1 per serving - ****Calories:** 350 kcal per serving - ****Source of:** Calcium, Vitamin A, C, K ### Ingredients - 4 large ripe tomatoes, cut into wedges - 1 cucumber, cut into thick half-moons - 1 green bell pepper, cut into rings or strips - 1 small red onion, thinly sliced - 150g (5 oz) Greek feta cheese, whole slab - 100g (¾ cup) Kalamata olives - 80ml (⅓ cup) extra-virgin olive oil - 1 tsp dried oregano ### Instructions 1. Cut the tomatoes into irregular wedges rather than neat slices; the varied shapes and sizes are part of horiatiki's rustic look. Season with salt and pepper, and let them sit briefly to release some juice, which will become part of the dressing. 2. In a large shallow bowl or plate, combine the tomatoes (with juice), cucumber, pepper, and onion. Don't mix yet—the [vegetables](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/) should maintain their distinct character rather than becoming muddled together. 3. Season the vegetables with salt and pepper, then drizzle with the extra-virgin olive oil. Sprinkle the oregano over everything. 4. Place the slab of feta directly on top of the vegetables—never crumble it beforehand. This presentation is presented traditionally, allowing everyone to break off pieces as they eat. Scatter the olives around the feta. 5. Drizzle a final thread of extra-virgin olive oil over the feta and add one more pinch of oregano. Let the salad sit for 5–10 min before serving; this allows the flavours to meld and the tomato juices to mix with the extra-virgin olive oil, creating a natural dressing at the bottom of the bowl. 6. Serve with bread for mopping up the dressing. The salad is best enjoyed within an hour of assembly, while the vegetables retain their texture and the feta its creamy integrity. --- ## 2\. Xato Salad Xato is a robust Catalan salad from the coastal towns south of Barcelona, particularly Sitges and Vilanova i la Geltrú, where it's celebrated with annual festivals. This hearty winter salad traditionally combines curly endive with salt cod, tuna, anchovies, and olives, all bound together by romesco-style xató sauce. The dish reflects Catalonia's genius for marrying bitter [greens](https://www.alphabetguides.com/superfood-leafy-greens/) with rich, savoury elements and a nutty sauce. However, this particular [recipe](https://www.alphabetguides.com/tag/recipes/) has been adapted slightly to make it easier to make. The fish provide lean protein and [omega-3 fatty acids](https://www.alphabetguides.com/superfood-oily-fish/), while the nuts give healthy fats, vitamin E, protein, and magnesium. This substantial salad serves as a complete meal; serve it with crusty bread for mopping up the xato sauce. recipe information - ****Serves:** 4-6 - ****Time:** 40 minutes - ****Cost:** \~$1.50 per serving - ****Calories:** 520 kcal per serving - ****Source of:** Protein, Fibre, Selenium, Omega-3, Vitamin C, E, K ### Ingredients **For the salad** - 300g (7 oz) quality tinned tuna in olive oil, drained - 1 head curly endive (escarole) or other bitter salad greens - 16 anchovy fillets - 100g (¾ cup) black olives **For the xató sauce** - 100g (¾ cup) blanched almonds, toasted - 50g (⅓ cup) hazelnuts, toasted and skinned - 2 cooked red peppers, seeded - 2 ripe tomatoes, roasted - 3 garlic cloves - 1 slice of day-old bread, fried in extra-virgin olive oil - 150ml (⅔ cup) extra-virgin olive oil - 2 tablespoons red wine vinegar ## Instructions 1. In a food processor, combine the toasted nuts, cooked peppers, roasted tomatoes, garlic, fried bread, vinegar, and a pinch each of salt and pepper. Process until finely ground and paste-like, scraping down the sides as needed. 2. With the motor running, slowly drizzle in the extra-virgin olive oil in a steady stream, as if making mayonnaise. The sauce will emulsify and transform into a thick, creamy, rust-coloured emulsion. If too thick, thin with a tablespoon of water. The consistency should be like thick double cream. Taste and adjust seasoning if necessary, 3. Arrange the torn green leaves on a large serving platter. Their sharp, bitter flavour balances the rich sauce and fatty fish. Distribute the chunks of tuna across the greens, keeping them in distinct sections rather than mixing everything. 4. Drape the anchovy fillets over the salad and scatter with the olives. These briny elements add essential saltiness and umami flavours that tie the dish together. Just before serving, spoon the xató sauce generously over the entire salad, ensuring every element gets coated. 5. Alternatively, serve the sauce on the side for guests to add themselves. The salad should be assembled and dressed immediately before eating. Serve with plenty of crusty bread to mop up the sauce. --- ## 3\. Insalata Tricolore “Insalata tricolore” is Italy's patriotic salad. It’s a simple arrangement of tomatoes, mozzarella, and basil that mirrors the red, white, and green of the Italian flag. Also known as Caprese salad (with avocado) after the island of Capri, where it allegedly originated. It represents the Italian philosophy that when produce is perfect, the cook's job is simply not to interfere. The fresh mozzarella provides [protein](https://www.alphabetguides.com/plant-based-protein/) and calcium, and the tomatoes provide fibre and vitamin C. It’s only a few ingredients, so it demands peak summer tomatoes and good quality fresh mozzarella; anything less diminishes its simple magic. Serve as an “antipasto”, light lunch, or side dish alongside grilled meats or fish. recipe information - ****Serves:** 4-6 - ****Time:** 10 minutes - ****Cost:** \~$1 per serving - ****Calories: \~**340 kcal per serving - ****Source of:** Protein, Calcium, Vitamin A, C, K ### Ingredients - 4 large high-quality ripe tomatoes (e.g., heirloom or beefsteak) - 2 balls (250g/9 oz) fresh buffalo mozzarella or “fior di latte” - Large handful of fresh basil leaves - 80ml (⅓ cup) extra-virgin olive oil - Flaky sea salt (for texture) and black pepper ### Instructions 1. Use tomatoes at room temperature — never refrigerated, which destroys their flavour and texture. Slice them thickly, about 1 cm (½ inch), removing the core. Arrange them on a large platter, slightly overlapping, and season immediately with flaky salt. This draws out their liquid and intensifies their flavour 2. Drain the mozzarella and pat it dry gently with paper towels; too much moisture will dilute the dressing. Slice into rounds roughly the same thickness as the tomatoes. Fresh mozzarella should be milky-white, tender, and slightly springy, never rubbery. 3. Tuck the mozzarella slices between and around the tomato slices, creating an alternating pattern (optional). The key is balance, ensuring each bite captures both elements (tomato and cheese). 4. Tear the basil leaves by hand rather than cutting them. A blunt knife bruises the delicate leaves and causes them to go black. Scatter the torn basil generously over the tomatoes and mozzarella, tucking some leaves underneath for visual interest. 5. Drizzle extra-virgin olive oil over everything. The oil should pool slightly around the tomatoes, mixing with their released juices to create a natural dressing. Finish with freshly cracked black pepper and an additional pinch of flaky salt over the mozzarella. 6. Let the salad rest for 5–10 minutes before serving to allow the flavours to harmonise. This brief rest lets the salt work its magic on the tomatoes, and the olive oil coats everything evenly. Serve with crusty bread to soak up the precious juices that collect on the platter. ![Tomato, basil and mozzarella salad.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1561363268-f17491a094bf.jpeg) --- ## 4\. Tabbouleh This quinoa tabbouleh is a Mediterranean adaptation of the Levantine herb salad, substituting traditional bulgur wheat with protein-rich quinoa from the Andes (although you are free to keep the original). The dish is a celebration of fresh herbs, lemon, and [vegetables](https://www.alphabetguides.com/3-healthiest-vegetables-around/) while offering a gluten-free alternative. Quinoa provides [high-quality protein](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/) along with iron, magnesium, and fibre, while the herbs deliver vitamins A, C, K and antioxidants. Serve as a light lunch, side dish, or part of a meze spread alongside hummus and warm flatbread for a plant-based meal. recipe information - ****Serves:** 4-6 - ****Time:** 1 hour - ****Cost:** \~$0.75 per serving - ****Calories:** 280 kcal per serving - ****Source of:** Fibre, Iron, Vitamin A, C, B9, K ### Ingredients - 150g (¾ cup) quinoa, rinsed well - 300ml (1¼ cups) water - 3 large bunches flat-leaf parsley (about 150g/5 oz), finely chopped - 1 bunch fresh mint (about 30g/1 oz), finely chopped - 4 ripe tomatoes, finely diced - 1 cucumber, finely diced - 4 spring onions, finely sliced - Juice of 2 lemons - 100ml (scant ½ cup) extra-virgin olive oil - 1 tsp ground cumin ### Instructions 1. Rinse the quinoa under cold running water in a fine-mesh sieve; this removes the natural bitter coating called saponin. Place in a small pot with the water, bring to a boil, then reduce the heat to low, cover, and simmer for 12–15 minutes until the water is absorbed, and the quinoa is tender. 2. Remove from heat and let stand covered for 5 minutes, then fluff with a fork and spread on a large plate or tray to cool completely. Cooling the quinoa prevents it from wilting the herbs and making the salad soggy; room-temperature quinoa is essential. 3. While the quinoa cools, wash and dry the parsley and mint (excess water will dilute the dressing). Remove the tough stems and chop the leaves finely. 4. In a large bowl, combine the cooled quinoa, chopped herbs, tomatoes, cucumber, and spring onions. The vegetables should be cut into small, uniform pieces. 5. In a small bowl, whisk together the lemon juice, extra-virgin olive oil, cumin, salt, and pepper until emulsified. Pour the dressing over the salad and toss gently but thoroughly, ensuring everything is evenly coated. Taste and adjust seasoning—tabbouleh often needs more lemon juice and salt than you expect. The flavours should be bold and vibrant. 6. Let the salad rest for at least 20 minutes before serving, allowing the quinoa to absorb the dressing and the flavours to mix. Tabbouleh is best served at room temperature or slightly chilled, and improves over a few hours. It keeps refrigerated for 2 days, though you may need to refresh it with extra lemon juice and extra-virgin olive oil before serving. --- ## 5\. Salad Niçoise Salade Niçoise is the jewel of Provence. It’s a salad from the sun-drenched port of Nice that typifies the French Riviera's approach to summer eating. This is not a tossed salad but an arrangement of vegetables, tuna, eggs, and olives that celebrates each ingredient's individuality. Purists debate its exact composition—cooked vegetables or raw? Potatoes or not? But all agree it must showcase the region's finest produce. The tuna provides lean protein and omega-3 fatty acids that support [heart](https://www.alphabetguides.com/tag/heart-health/) and [brain health](https://www.alphabetguides.com/tag/brain-health/). And the green beans are a good source of vitamin C and K. This salad is a complete, balanced meal that requires no cooking beyond boiling eggs and beans, which can be done in advance. recipe information - ****Serves:** 4 - ****Time:** 30 minutes - ****Cost:** \~$1.50 per serving - ****Calories:** 480 kcal per serving - ****Source of:** Protein, Fibre, Selenium, Omega-3, Vitamin A, B9, C _This post is for subscribers only._ ### The 7 Key Foods of the Mediterranean Diet URL: https://www.alphabetguides.com/mediterranean-diet-foods/ Last updated: 2026-09-21T10:02:19.000Z summary - The health benefits of the Mediterranean diet do not come from a single "superfood," but rather a mixture of different healthy whole foods. - The diet is defined by a clear list of foods: plant-based, healthy fats from fish and olive oil, and small amounts of high-quality meat and dairy. - Rather than "good vs. bad", it categorises foods by frequency: what to eat daily, weekly, and what to treat as a rare exception. The [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/) is consistently cited by nutritionists, scientists and health organisations as one of the world's healthiest diets. So, understanding *why* it works requires knowing exactly what (and what shouldn't) find its way onto your plate. The diet is rooted in traditional food and eating habits that have been refined over centuries. By swapping out [ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/) for nutrient-dense whole foods, plants, healthy fats, and lean proteins, this way of eating (and living) has decades of research suggesting that it has a host of health benefits that work *with* human instincts, not against them. Has there been any other [diet](https://www.alphabetguides.com/tag/diet/) that has been put under the same scrutiny, or has stood the test of time better than any other? We don't think so. So, this article breaks down the seven foundational foods of the Mediterranean diet and the specific role each of them has in protecting your health. ## On this page: 1. [Fish and seafood](https://www.alphabetguides.com/mediterranean-diet-foods/#fish-and-seafood) 2. [Whole grains](https://www.alphabetguides.com/mediterranean-diet-foods/#whole-grains) 3. [Legumes](https://www.alphabetguides.com/mediterranean-diet-foods/#legumes) 4. [Extra virgin olive oil](https://www.alphabetguides.com/mediterranean-diet-foods/#extra-virgin-olive-oil) 5. [Dairy and fermented foods](https://www.alphabetguides.com/mediterranean-diet-foods/#dairy-and-fermented-foods) 6. [Vegetables](https://www.alphabetguides.com/mediterranean-diet-foods/#vegetables) 7. [Red meat and processed meat](https://www.alphabetguides.com/mediterranean-diet-foods/#red-meat-and-processed-meat) --- ## 1\. Fish and seafood ****Summary:** Consuming fish twice a week reduces heart and brain disease risk due to the the protective effects of the omega-3 fatty acids. Beyond the essential fatty acids, fish provides high-quality protein, vitamins D and B, and several minerals. Compared to standard [Western diets](https://www.alphabetguides.com/western-diet/), fish and seafood have a central place in the Mediterranean diet. They provide unique nutrients that contribute to the diet’s health benefits. It’s no coincidence that other healthy regions around the world (i.e., “[blue zones](https://www.alphabetguides.com/blue-zone/)”) all seem to have higher than average intake of fish and seafood. They seem to particularly like the cheap, fresh, local, and sustainable oily species that are rich in omega-3 fatty acids (e.g., anchovy, mackerel, sardines). Regular consumption of this type of fish represents one of the Mediterranean diet's most distinctive features. The cardiovascular health benefits of fish intake are well researched. Consuming fish two to three times weekly reduced deaths caused by cardiovascular disease compared to lower intakes of fish.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/32751304/?ref=alphabetguides.com) These benefits are thought to come from the long-chain omega-3 [fatty acids](https://www.alphabetguides.com/superfood-oily-fish/): eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These nutrients are shown to reduce inflammation, improve blood vessel health and your blood lipid profile.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/22051327/?ref=alphabetguides.com) Beyond the cardiovascular benefits, regular intake of fish supports [brain health](https://www.alphabetguides.com/tag/brain-health/). The human brain is nearly 60% fat, with DHA being an important component of your nerves. Regular fish intake (particularly of the fatty species) has been associated with slower cognitive decline, reduced dementia risk, and better memory in older adults. Studies suggest that consuming fish at least twice a week may reduce Alzheimer's disease risk, with benefits more obvious when fish replaces red meat.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/26718417/?ref=alphabetguides.com) The nutritional benefits of fish also extend beyond omega-3s. Seafood provides high-quality protein, meaning it is beneficial for maintaining [muscle mass](https://www.alphabetguides.com/tag/muscle/). Fish also provides essential micronutrients that are often lacking in modern diets: vitamin D, selenium, iodine, and B vitamins, particularly vitamin B12\. Smaller fish, which are commonly consumed whole (like sardines and anchovies), also provide calcium from their edible bones, which can support the health of your own bones. Sustainability and safety considerations matter when adding fish to your diet. Fatty fish like salmon, mackerel, sardines, herring, and anchovies offer the highest omega-3 content and are generally among the more sustainable choices. Smaller fish, lower on the food chain, also tend to accumulate fewer environmental contaminants like mercury compared to the large predatory ones. Practical implementation is straightforward: - Aim for at least two servings of fish a week, with at least one being a fatty variety rich in omega-3s. A single serving only equals approximately 3–4 ounces (85–115 g) once cooked. - If you don’t like the flavour of fish, try some [simple Mediterranean preparations](https://www.alphabetguides.com/mediterranean-diet-meal-plan/). Grill it with lemon and herbs. Bake it with tomatoes and olives. Pan-sear it with garlic, rosemary, and olive oil. Gently poach it with aromatic vegetables. - Canned fatty fish like tuna, sardines, mackerel, and wild salmon offer convenience and affordability while providing the same health benefits as fresh varieties, making regular consumption more accessible to everyone. --- ## 2\. Whole grains ****Summary:** Eating two to three portions of whole grains a day (in place of refined grains), is beneficial for health and disease prevention. Traditionally, whole grains are eaten in moderate portions alongside vegetables, legumes and olive oil. The distinction between whole grains and refined grains *is* important. Traditionally, Mediterranean people consumed grains in minimally processed forms: whole wheat bread, bulgur wheat, farro, barley, and brown rice. These whole grains retain their nutrient-rich bran and germ. Studies have shown that consuming three servings of whole grains a day reduces the chances of dying from nearly all major [diseases](https://www.alphabetguides.com/tag/health/). But these benefits (mostly) disappear when the grains are refined.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/22166190/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/19079919/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/31682258/?ref=alphabetguides.com) The health benefits of whole grains seem to come from the combination of nutrients they provide. - The bran layer provides a lot of fibre, both soluble and insoluble, which slows digestion, stabilises blood sugar levels, lowers cholesterol, and feeds your “good” gut bacteria. - The germ of the whole grain also contains B vitamins, vitamin E, healthy fats, and minerals (like magnesium, selenium, and zinc). Whole grains also deliver phytonutrients that have antioxidant and anti-inflammatory properties. This combination of many different nutrients works together in ways that isolated nutrients can't replicate (known as the "[food matrix effect](https://www.alphabetguides.com/food-matrix/)").[\[7\]](https://pubmed.ncbi.nlm.nih.gov/27301975/?ref=alphabetguides.com) Whole grains support health in many ways: - Their fibre content improves insulin sensitivity and helps control blood sugar, making them valuable for the prevention and management of diabetes. - The “resistant starch” in whole grains reaches your colon intact (i.e., not digested or absorbed), where it ferments to produce short-chain fatty acids. These short-chain fatty acids reduce inflammation and support gut and metabolic health. - Regular intake of whole grains is also associated with a healthier body weight, probably because they keep you feeling fuller for longer.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/22357746/?ref=alphabetguides.com) As part of the Mediterranean diet, whole grains are typically consumed as part of balanced meals rather than by themselves. Whole-grain bread accompanies vegetable-rich stews, bulgur wheat forms the base of tabbouleh: a salad loaded with herbs and vegetables, barley is added to soups along with legumes, and pasta (preferably whole wheat) is served with tomato sauces and vegetables. Combining whole grains with other Mediterranean foods increases the absorption of some of their nutrients and improves their flavour. The easiest way to get more of them into your diet is to replace [refined grains](https://www.alphabetguides.com/ultra-processed-food-diet/) with whole grain alternatives: choose whole wheat or whole grain bread over white, brown rice or farro over white rice, whole wheat pasta over regular, and steel-cut or rolled oats over instant oats and cereals. For most people, a lot can be gained by making this [simple switch](https://www.alphabetguides.com/mediterranean-one-pot/). Portion sizes on the Mediterranean diet tend to be "moderate", meaning roughly half to one cup of cooked grains per meal. Grains serve as a base for [vegetables](https://www.alphabetguides.com/3-healthiest-vegetables-around/), legumes, and healthy fats rather than dominating the plate. Ancient grains like farro, bulgur, freekeh, and barley offer nutritional variety, along with authentic Mediterranean flavours, if you want to keep it traditional. --- ## 3\. Legumes ****Summary:** Daily intake of legumes is linked to better blood sugar control and lower cholesterol. They are an affordable and tasty source of protein, resistant starch, complex carbohydrates, fibre (soluble and insoluble), several vitamins, minerals, and other nutrients that are beneficial for health Legumes: beans, lentils, chickpeas, and peas are an important part of the traditional Mediterranean diet. They provide affordable, nutritious, high-quality [plant protein](https://www.alphabetguides.com/plant-based-protein/) that contributes towards the diet's health benefits. Several studies have reported that higher legume intake is associated with a reduction in the risk of cardiovascular disease, type 2 diabetes, and overall death rates.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/24898241/?ref=alphabetguides.com) The nutritional content of legumes explains their protective effects. They provide a rare combination of protein, complex carbohydrates, and *both* soluble and insoluble fibre in one food. All these nutrients work together to help control blood sugar levels better, improve satiety and fullness, and support good metabolic health.[\[10\]](https://pubmed.ncbi.nlm.nih.gov/31728500/?ref=alphabetguides.com) Legumes have a low glycemic index, meaning they cause gradual rather than rapid rises in blood sugar, making them particularly valuable for diabetes prevention and management. Their soluble fibre binds with cholesterol in your digestive system, helping lower “bad” LDL cholesterol levels and reducing cardiovascular disease risk.[\[11\]](https://pubmed.ncbi.nlm.nih.gov/28392166/?ref=alphabetguides.com) Beyond macronutrients, legumes deliver an impressive mix of micronutrients that are often missing in most diets. They're rich in folate, iron, magnesium, potassium, and zinc. These minerals are crucial for everything from red blood cell formation to bone health and keeping the immune system working. Legumes also provide nutrients with antioxidant and anti-inflammatory properties. Their resistant starch reaches the colon “intact”, meaning it feeds “good” gut bacteria that support health. They are the natural “prebiotics” that improve gut microbiome diversity and health.[\[12\]](https://doi.org/10.1016/j.cofs.2017.01.005?ref=alphabetguides.com) Legumes appear in countless [traditional Mediterranean dishes](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/). They’re generally combined with other ingredients (including other carbohydrates like whole grains and vegetables) and other flavourful ingredients (like olive oil, herbs, and spices). Greek fasolada (white bean soup), Italian pasta e fagioli, Spanish lentil stew, Middle Eastern hummus and falafel, and Turkish bulgur-lentil pilaf are just a few famous examples. The practice of soaking dried legumes and cooking them slowly not only improves their digestibility but also improves their nutritional content. Legumes are cheap, easy to cook, and can be stored for months. Aim for at least three servings a week, or daily for maximum benefits. A single serving is only half a cup cooked (80-90 g).[\[13\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4608274/?ref=alphabetguides.com) Canned legumes are readily available and offer convenience as they are already cooked. They can be added to bulk out and improve the nutrition of soups, stews, and salads. They can also be puréed and made into healthy dips and spreads (like chickpea hummus). Not only that, but they can even be used to replace some meats in traditional Mediterranean dishes. [Health Benefits of Legumes: Just One Can a WeekAdding just one simple can of legumes a week to your weekly shop can transform your heart and gut health, your wallet, and the planet.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-3a66508b-3e91-4e1a-975c-879cca307899.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1599579085809-4edbc35cee01-d943edbc-04fe-456f-9555-57b0cd964175.jpg)](https://www.alphabetguides.com/legumes-and-health/) --- ## 4\. Extra virgin olive oil ****Summary:** By itself, just four tablespoons of extra virgin olive oil a day improves cardiovascular health. It also reduces the risk of many other diseases, due to its anti-inflammatory properties. Choose high-quality olive oil where possible, replacing rather than supplementing other fats. The health benefits of extra virgin olive oil are well researched. Studies have shown that consuming extra virgin olive oil (\~ 4 tbsp a day) improved [cardiovascular health](https://www.alphabetguides.com/tag/heart-health/) and protected against “cardiovascular events” (like heart attacks and strokes).[\[14\]](https://pubmed.ncbi.nlm.nih.gov/24886626/?ref=alphabetguides.com) These benefits are thought to come from its unique fatty acid profile. The “monounsaturated” oleic acid in extra virgin olive oil is thought to improve cholesterol ratios, reduce “bad” LDL cholesterol, and improve blood vessel function compared to other fats.[\[15\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4586551/?ref=alphabetguides.com) In addition to its healthier fat profile, [extra virgin olive oil is unique](https://www.alphabetguides.com/superfood-olive-oil/), as it offers a high concentration of “polyphenols”: plant compounds with antioxidant and anti-inflammatory properties. “Oleocanthal”, one of the most studied polyphenols, has anti-inflammatory effects that have been compared to ibuprofen. “Oleacein” and “hydroxytyrosol” are other antioxidants found in extra virgin olive oil that protect your cells and their contents, and prevent premature biological ageing. Studies have shown that the higher polyphenol content of extra virgin olive oil reduces inflammation and blood pressure and improves blood vessel health compared to other refined oils.[\[16\]](https://pubmed.ncbi.nlm.nih.gov/30487558/?ref=alphabetguides.com) Extra virgin olive oil intake has also been associated with reduced risk of type 2 diabetes, certain cancers, cognitive decline, and better [brain health](https://www.alphabetguides.com/tag/brain-health/). The polyphenols in the extra virgin olive oil can get into the brain, where they reduce inflammation and keep the brain functioning properly.[\[17\]](https://pubmed.ncbi.nlm.nih.gov/21801436/?ref=alphabetguides.com)[\[18\]](https://pubmed.ncbi.nlm.nih.gov/23732551/?ref=alphabetguides.com) Lastly, the healthy fats found in extra virgin olive oil can also help the absorption of fat-soluble vitamins (A, D, E, K) and antioxidants from vegetables (e.g., carotenoids, lycopene) when they're consumed at the same time. Not all olive oils are created equally. The "extra virgin" classification means the oil comes from the first cold pressing of olives *without* any chemical processing. This is important because it preserves maximum polyphenol content. High-quality extra virgin olive oil typically has a peppery, slightly bitter taste as the polyphenols create a sensation of burning in the back of the throat. Storage is equally important: light, heat, and oxygen degrade some of these beneficial compounds, so choose oils in dark bottles, store away from heat and light, and use within a few months of opening. While cost often reflects quality, not all expensive oils are superior; look for harvest dates, certifications, and single-origin sources where possible. Right away, you can start using extra virgin olive oil as your primary fat for cooking (under 375°F or 190°C) and finishing soups, stews, salads, whole grains, and really most types of [Mediterranean dishes](https://www.alphabetguides.com/mediterranean-breakfast-ideas/). It tends to complement everything. It’s even used to make cakes, cookies, and desserts in the Med. Researchers have reported that you can even lose weight and improve health while still consuming quite a lot of extra virgin olive oil, despite it being calorie-dense16. But simply replacing all other refined fats with extra virgin olive oil, where you can, is a good first step to getting it into your diet. ![Olive tree with olive in the sunlight.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1609763951640-c0d7bd98b257.jpeg) --- ## 5\.

It is metabolically active and releases substances that are devastating for your cardiometabolic health. - People with normal body weight can still have high levels of visceral belly fat. Overweight people can actually have normal amounts of it as well. - You can't "spot-burn" visceral fat, but there are dietary, nutritional, and exercise interventions that you can do to reduce it. Not all body fat is created equal. There are healthy types and healthy amounts of body fat. And there are unhealthy amounts and unhealthy types of body fat. And there are also less unhealthy types of fat (i.e., not great for your health, but it could be worse). The amount of each type of fat and where it is located in the body can be critical for your health and future [fat loss](https://www.alphabetguides.com/tag/fat-loss/) prospects. “Visceral” fat is the deep abdominal fat that surrounds your internal organs. It poses *significantly* greater health risks than the “subcutaneous” fat does (i.e., that fat you can pinch under your skin). ## Internal fat vs. external fat: visceral vs subcutaneous fat Visceral fat, technically referred to as “visceral adipose tissue”, is stored *within* the abdominal cavity of your body. It wraps around organs such as your liver, pancreas, and intestines. Whereas the "subcutaneous adipose tissue" lies directly beneath the skin and serves mainly as energy storage and insulating material. Visceral fat is more metabolically active, but not in a good way: it releases fat, inflammatory molecules and [hormones](https://www.alphabetguides.com/tag/hormones/) directly into your bloodstream. These differences between visceral fat and subcutaneous fat explain why two people with similar body weights and the same amount of “fat tissue” can have completely different metabolic health prospects.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/11133069/?ref=alphabetguides.com) You can carry significant visceral fat even if you appear relatively lean. “Skinny fat” is a term that’s used when someone is of normal body weight but has a large amount of fat. We tend to see this a lot with older people and inactive women, where the negative health impact is exacerbated by the fact that they also have a low amount of healthy [muscle tissue](https://www.alphabetguides.com/tag/muscle/). This means that some people can have a perfectly normal body size, body weight, and BMI, but underneath the bonnet, they're carrying too much fat (visceral and/or subcutaneous). Conversely, some people who appear to have higher body fat may actually have relatively low amounts of visceral fat. This highlights why body weight *alone* (and BMI) is not always a good [measure of health](https://www.alphabetguides.com/beyond-the-scale/).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/11133069/?ref=alphabetguides.com) ## How visceral fat affects your health Large amounts of visceral fat dramatically increase your risk of several serious diseases (e.g., diabetes, cardiovascular disease, metabolic disease, and inflammatory conditions) irrespective of your body weight. It also promotes “insulin resistance” by releasing fat into your bloodstream. This disrupts liver function and leads to "ectopic" liver fat or non-alcoholic “fatty liver disease”. In turn, this means your liver struggles to control your blood sugar, blood pressure, and body fat levels and increases the risk of cardiovascular disease. These conditions, where several of your body's processes simultaneously start to fail, are so common that they've been given their own name: “metabolic syndrome”, which is tied to obesity and high levels of visceral fat. The closer your fat is stored to these vital organs, the greater its potential to disrupt their normal functions.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/11133069/?ref=alphabetguides.com) ## How to measure visceral belly fat The gold standard for [measuring visceral fat](https://www.alphabetguides.com/candy-apple-phenotype/) is imaging techniques like CT, DEXA or MRI scans, but these are expensive and impractical for routine monitoring. Fortunately, waist circumference can provide a good, reliable proxy measure. Research indicates that a waist circumference exceeding 102 cm (40 inches) for men and 88 cm (35 inches) for women indicates that you have high visceral fat. To measure your waist circumference correctly: - Place a tape measure around your natural waist (i.e., the narrowest point about halfway between your lowest rib and the top of your hip bone). - Do this whilst standing and breathing normally. Avoid the common mistake of measuring at the widest part of your hips or pulling the tape too tight. - Track this measurement monthly along with body weight for a more accurate assessment of how much fat you're losing. - It is best to take both these measures at the same time, first thing in the morning, before eating or drinking anything. Waist-to-height ratio can also be used, and is actually more accurate. Having a waist measurement over half of your height is a common cut-off for increased risk of disease and normal amounts of body fat. “Keep your waist to less than half your height” is a simple and effective way to think about your body fat levels. --- ## How to Reduce Visceral Fat _This post is for subscribers only._ ### What is Blood Flow Restriction Training and Does it Work? URL: https://www.alphabetguides.com/blood-flow-restriction-training/ Last updated: 2026-09-18T11:48:41.000Z summary - Restricting (venous) blood flow from your muscle while training stimulates growth when lifting weights that are 20-30% lighter. - It's used for injury recovery, joint issues, and preserving muscle in older adults without overloading their joints and connective tissues. - Proper equipment and technique are required for safety. Specialised pressure-measuring cuffs and professional guidance are essential. Blood flow restriction training (or “Kaatsu”) involves partially restricting blood flow to a limb (or limbs) while you [exercise](https://www.alphabetguides.com/tag/exercise/). To do this, you'll apply a specialised cuff around your upper arms or upper thighs. It works like a blood pressure cuff or elastic band, being tightened just enough to start limiting the blood returning to your heart (via your veins), while still allowing blood to flow into your muscles (through the arteries).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/34530434/?ref=alphabetguides.com) Put simply, your muscles are still being filled with blood, but it can’t escape as easily. The result? Well, your muscles swell, burn, and fatigue a lot quicker. This even happens with a lightweight that would feel easy under normal conditions.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/25249278/?ref=alphabetguides.com) The best way to think of blood flow restriction training is that you're putting the “brakes on” while you're riding a bike; you’re still moving, but every push feels harder. Blood flow restriction creates a similar "internal resistance" in your muscles. They tire out sooner, your muscles get stressed more easily, and this is thought to give your body a stronger "signal" to [adapt and grow](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/). So why not just lift heavier weights without restricting blood flow?Well, you can — and often that’s still the most efficient way to [build muscle](https://www.alphabetguides.com/tag/muscle/). However, there are certain situations where lifting lighter weights is advantageous. Consider three scenarios: an athlete recovering from surgery, someone with painful joints, or an older adult with arthritis. For these people, blood flow restriction allows them to get many of the muscle-building benefits with less weight.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31156448/?ref=alphabetguides.com) ## Does blood flow restriction training work? The secret lies in how it alters your internal environment while you exercise. Blood flow restriction reduces the availability of oxygen to working muscles. This creates a state called "hypoxia". Under these low-oxygen conditions, your body “recruits” more muscle more quickly (particularly the fast Type II fibres), which (in theory) will mean more growth. At the same time, metabolites like lactate and hydrogen ions accumulate more quickly. This causes the burning sensation and is thought to stimulate muscle growth. The "metabolic stress" that's accumulated is thought to act as a powerful trigger for muscle growth. So, it basically makes lighter loads feel heavier (or harder) than they should.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/25249278/?ref=alphabetguides.com) #### Blood Flow Restriction Training Guidelines - ****Pressure:** 40%–80% of arterial occlusion pressure. Lower for smaller limbs or comfort. - ****Time:** Total restriction time of less than 10 minutes total. Remove the restriction to allow "reperfusion" between sets and exercises. - ****Execution:** Perform to, or close to, failure, or when planned reps are completed; 20-40% 1RM; 2-3 total sets per exercise; 10-30 reps per set; 30-60 seconds rest.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31156448/?ref=alphabetguides.com) --- ## The benefits of blood flow restriction training One of the standout benefits of blood flow restriction training is how relatively gentle it is on your joints. Because you’re using just 20–30% of your normal loading, there’s less wear and tear on your joints. This makes it a good option if you're dealing with an injury, undergoing surgery, or just trying to reduce joint stress during a [deload week](https://www.alphabetguides.com/how-to-deload/). Even on days when you're low on time or energy, a short session can be effective. It’s also shown to help older adults maintain or regain muscle mass, especially when traditional strength training isn’t an option (e.g., due to pain or mobility limitations).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/34530434/?ref=alphabetguides.com) ## Is blood flow restriction training safe? The main safety concern with blood flow restriction training is excessive pressure. If the bands or cuffs are too tight, they can completely block arterial blood flow. This increases the risk of nerve damage, [muscle damage](https://www.alphabetguides.com/doms/), blood vessel injury, or, in rare cases, blood clots. Using makeshift gear, like resistance bands or tourniquets, with no way to measure the pressure they're exerting, is particularly risky and should be avoided. Professionals will use specialised cuffs that measure "occlusion pressure" as a percentage of the “arterial occlusion pressure” (AOP), which is basically the smallest amount of pressure needed to block arterial blood flow. For [resistance training](https://www.alphabetguides.com/minimalist-muscle-growth/), much lower pressures are used (around 40–80%). Wider cuffs generally need less pressure to achieve the same level of occlusion. Use purpose-built equipment. When possible, stay within the safe range and get help from a trained professional. Research shows that when done with proper technique and caution, the risk of adverse effects of blood flow restriction training is low.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/35284924/?ref=alphabetguides.com) #### ⛔Risk Factors Blood flow restriction training should be avoided if any of the following are present:[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31156448/?ref=alphabetguides.com) 1. Self-reported easy bruising. 2. Any acute illness. 3. Any medical problem that may be life-threatening. 4. More than one cardiovascular risk factor is present. --- ## Bottom Line Blood flow restriction training is used in rehab settings as it allows gains to be made with lower mechanical loads. Wrapping a random strap around your limb and tightening it until it hurts *is* dangerous. That’s why know-how and appropriate equipment are vital. It should be used like a power tool: effective in the right hands, but not something to be used carelessly by novices.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/35360229/?ref=alphabetguides.com) --- #### Sources 1.

The Mediterranean diet is more of an eating pattern than a diet, which is based on eating (mostly) plants, olive oil, fish, and minimally processed foods. Few diets have withstood the scrutiny of modern science quite like the [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/) has. While most diets rely on eliminating certain things and strict rules, the Mediterranean diet is a traditional way of eating that works by reducing inflammation and improving cardiometabolic health. Some of the healthiest people in the world have followed it for millennia, and it is backed by decades of research. By looking at human biology as a "connected system" (i.e., one solution to many problems), this article breaks down the underlying science behind its seven core health and longevity benefits. ## On this page: 1. [Cardiovascular health](https://www.alphabetguides.com/mediterranean-diet-health-benefits/#1-cardiovascular-health) 2.

[Cancer risk](https://www.alphabetguides.com/mediterranean-diet-health-benefits/#5-cancer-risk) 7. [Healthy bodyweight](https://www.alphabetguides.com/mediterranean-diet-health-benefits/#6-healthy-bodyweight) --- ## #1\. Cardiovascular health ****Summary:** The Mediterranean diet reduces cardiovascular disease risk and the chances of having a stroke or heart attack. It reduces blood pressure and lipids. The healthy fats from olive oil, nuts and fish, fibre and antioxidant-rich foods are thought to be the main drivers of its benefits. Cardiovascular disease remains the leading cause of death worldwide, and it has been that way for a long time. The Mediterranean diet stands as one of the best dietary approaches for protecting your [heart health](https://www.alphabetguides.com/tag/heart-health/), with decades of research behind it. A study in adults with a high risk of cardiovascular disease reported that those who followed the Mediterranean diet (supplemented with extra virgin olive oil or nuts) reduced their risk of “cardiovascular events” (i.e., heart attack, stroke, or death) by around 30%.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/29897866/?ref=alphabetguides.com) These results were so obvious that after the study was stopped, the researchers advised all the participants who were in the study (including those in the control group) to follow the Mediterranean diet. One of the main advantages of the Mediterranean diet is that it addresses several cardiovascular risk factors at the same time: - It reduces “bad” LDL cholesterol - Raises “good” HDL cholesterol - Lowers blood pressure - Reduces blood triglycerides - Improving control of your blood sugar levels. It positively affects nearly every modifiable risk factor, and consequently, risk of several cardiovascular diseases (e.g., coronary heart disease, stroke, and blood vessel health).[\[2\]](https://pubmed.ncbi.nlm.nih.gov/29177567/?ref=alphabetguides.com) The reason the Mediterranean diet benefits [heart health](https://www.alphabetguides.com/heart-health-diets/) is thought to come from its unique combination of different “cardio-protective” nutrients. Cited nutrients include:[\[3\]](https://pubmed.ncbi.nlm.nih.gov/30817261/?ref=alphabetguides.com) - Extra virgin [olive oil](https://www.alphabetguides.com/superfood-olive-oil/) provides monounsaturated fats and antioxidants that reduce inflammation and oxidative stress in the walls of your arteries. - The omega-3 fatty acids from fish protect against heart arrhythmias, reduce blood clotting, and lower your blood triglyceride levels. - The fibre from vegetables, fruits, [legumes](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/), and whole grains helps reduce cholesterol and improve the control of blood sugar. - Nuts provide plant sterols, healthy fats, and arginine that keep blood vessels healthy. - The antioxidants from colourful produce protect LDL cholesterol from oxidation, which can reduce the build-up of atherosclerotic plaque in your blood vessels. ### When should you start the diet? Or is it ever too late to start? The good news is that the Mediterranean diet is beneficial for protecting against cardiovascular disease for those who are currently healthy, already have, or have had cardiovascular disease. Studies show the Mediterranean diet can reduce readmissions to the hospital, improve quality of life and cardiovascular health in people who already have heart problems. Specific components of the Mediterranean diet can be prioritised for heart health. For example: - Use of extra virgin olive oil as your primary fat source. - Consume a handful of mixed nuts (about 30 grams) instead of [junk food](https://www.alphabetguides.com/how-to-avoid-upfs/) snacks. - Include fatty fish twice a week for omega-3s. - Fill half your plate with vegetables at [meals](https://www.alphabetguides.com/mediterranean-breakfast-ideas/). - Choose whole grains over refined carbohydrates. - Eat legumes several times a week. - Limit red meat and avoid processed meats where possible. The aim is to create a dietary environment that protects and possibly improves your cardiovascular health. There is nothing intrinsically magical about the diet itself.[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC10421390/?ref=alphabetguides.com) --- ## #2\. Diabetes and metabolic health ****Summary:** The Mediterranean diet reduces the risk of Type 2 Diabetes. For diabetics, the diet improves their ability to control blood sugar, insulin sensitivity and medication requirements, outperforming most diets. Type 2 diabetes (T2D) is a pressing global health challenge. Yet, the Mediterranean diet is good for both the prevention and management of T2D. People following Mediterranean diet patterns reduced their risk of T2D by nearly a quarter. The protective effect of the diet remains even after controlling for body weight, suggesting the Mediterranean diet can reduce T2D risk with or without weight loss.[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3161259/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/26260349/?ref=alphabetguides.com) However, the benefit appears “dose-dependent”, meaning the closer you follow the diet, the better the results; but even low to moderate adherence to the diet will still provide some benefits. For people already diagnosed with T2D, studies have shown that patients who follow the diet (supplemented with extra virgin olive oil or nuts) have better glycaemic control, lower blood sugar levels, and reduced need for medication.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/20929998/?ref=alphabetguides.com) ### How? The mechanisms underlying these benefits are well known. The diet emphasises low “glycemic index” (GI) foods (e.g., whole grains, legumes, and non-starchy vegetables). These low-GI carbohydrates prevent blood sugar spikes and allow the body to handle blood sugar levels better if or when they do spike. Healthy fats from olive oil and nuts enhance the body's ability to use insulin effectively. The high fibre content of the diet slows absorption of carbohydrate and supports the “good” gut bacteria that keep your blood sugar levels under control. The antioxidants from extra virgin olive oil also have anti-diabetic effects, improving pancreatic “beta-cell function” and reducing inflammation that interferes with the release of insulin. The Mediterranean diet addresses some of the associated cardiovascular complications that make diabetes particularly dangerous. People with diabetes face a two to four times higher risk of heart disease. However, the Mediterranean diet also (simultaneously) improves many cardiovascular risk factors (e.g., blood pressure, lipid profile, inflammation, and blood vessel health), providing other [health benefits](https://www.alphabetguides.com/mediterranean-diet-fat-loss-health/) outside of your blood sugar levels.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/25369829/?ref=alphabetguides.com) ### What to target - Prioritise non-starchy vegetables, which can be eaten freely. - Choose whole grains in moderate portions rather than refined, processed carbohydrates. - Include legumes regularly; their combination of [protein](https://www.alphabetguides.com/plant-based-protein/), fibre, and low-GI carbohydrates provides energy without blood sugar spikes. - Use nuts as snacks instead of processed foods. - Cook with extra-virgin olive oil and [eat fatty fish](https://www.alphabetguides.com/superfood-oily-fish/) twice a week. - Limit sweet fruits to one to two servings a day, and prioritise berries and citrus fruits. --- ## #3\. Brain health and cognition ****Summary:** People who follow the Mediterranean diet have lower rates of dementia and better cognitive function. The nutritional profile of the diet is thought to preserve brain size, slow brain shrinkage, improve blood flow and brain cell health in some of the most important regions of the brain. The evidence connecting the Mediterranean diet to [better brain health](https://www.alphabetguides.com/brain-health-diets/) is substantial and still growing. Studies have shown that high adherence to the Mediterranean diet was associated with reduced risk of dementia (by a third) and better performance across several cognitive tests.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/28657600/?ref=alphabetguides.com)[\[10\]](https://pubmed.ncbi.nlm.nih.gov/29566197/?ref=alphabetguides.com) The mechanisms behind these cognitive benefits are reasonably well understood. The Mediterranean diet delivers a unique combination of “neuroprotective” compounds: - Omega-3 fatty acids from fish support the membranes of the nerves in your brain and reduce inflammation. - The antioxidants from extra virgin olive oil, berries, vegetables, and red wine can combat oxidative stress and cell damage in the brain. - The B vitamins from [leafy greens](https://www.alphabetguides.com/superfood-leafy-greens/) support “homocysteine metabolism”, which is harmful (“neurotoxic”) if it starts accumulating in the brain. Brain imaging studies provide visual evidence of these positive effects, showing that older adults who follow the diet maintain larger brain volumes, particularly in regions used for memory and mental skills that you need for everyday tasks. The diet appears to slow the brain shrinking that typically increases after the sixth decade of life. This effectively keeps the brain “younger” than your chronological age.[\[11\]](https://pubmed.ncbi.nlm.nih.gov/26491085/?ref=alphabetguides.com) Beyond preventing decline, the diet supports cognitive performance in healthy adults. Studies demonstrate *some* improvements in memory, attention, and mental skills like [planning](https://www.alphabetguides.com/mediterranean-diet-meal-plan/), decision-making, and problem-solving. These “clear thinking” benefits emerge relatively quickly, with studies reporting measurable changes in months.[\[12\]](https://pubmed.ncbi.nlm.nih.gov/28710144/?ref=alphabetguides.com) The “[MIND diet](https://www.alphabetguides.com/mind-diet/)” is specifically designed for brain health by combining elements of the Mediterranean and [DASH diets](https://www.alphabetguides.com/dash-diet/). The diet emphasises “brain-healthy foods” (e.g., leafy greens, berries, nuts, olive oil, whole grains, fish, beans, and poultry) while limiting “brain-unhealthy foods” (e.g., red meat, butter, cheese, pastries, and fried foods). Studies suggest the MIND diet may be effective at slowing cognitive decline for those who want to prioritise their brain health. The practical implications are clear: protecting your brain doesn't require extreme or complex approaches.[\[13\]](https://pubmed.ncbi.nlm.nih.gov/31209456/?ref=alphabetguides.com) - Regular consumption of oily fish (twice-weekly) - Daily servings of leafy greens and other [colourful vegetables](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/) - Use nuts as snacks, extra virgin olive oil as your primary fat - Eat berries several times per week. These form the foundation of a “brain-health” eating pattern. The earlier you start, the better, but research shows benefits even when dietary changes are moderate, or begin in midlife or later. --- ## #4\. Healthy ageing ****Summary:** The Mediterranean diet extends both lifespan and healthspan. It improves the quality of life in later years by preserving cognitive and physical function. It also reduces the risk of several age-related diseases, all at the same time. Studies consistently show that people who follow Mediterranean-style dietary patterns tend to live longer. A study found that those who followed the Mediterranean diet reduced death rates by over a fifth. In addition to extending life, the diet protects cardiovascular, cognitive and physical health, which decline as we age.[\[14\]](https://pubmed.ncbi.nlm.nih.gov/28488692/?ref=alphabetguides.com)[\[15\]](https://pubmed.ncbi.nlm.nih.gov/18494169/?ref=alphabetguides.com) The concept of “healthspan” is the period of your life spent in good health (i.e., free from chronic disease and disability). Studies show that older adults following a Mediterranean diet experienced improvements in quality of life and reduced frailty. Participants maintained better physical function, cognitive performance, and independence in their later years.[\[16\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC12771096/?ref=alphabetguides.com) The benefits of the Mediterranean diet on healthy ageing are thought to come from the abundance of antioxidants (from olive oil, colourful fruit and veg), omega-3 fatty acids from oily fish, and the fibre from whole grains, fruit and veg. These nutrients are thought to work together to reduce inflammation that underlies a lot of age-related diseases.[\[17\]](https://pubmed.ncbi.nlm.nih.gov/26528631/?ref=alphabetguides.com) One example is telomeres: the protective caps around our chromosomes that keep our DNA healthy. Unfortunately, these tend to shorten as we age, damaging our DNA. People who follow the Mediterranean diet tend to have longer telomeres, potentially slowing ageing at the cellular level.[\[18\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC7666892/?ref=alphabetguides.com) More importantly, the diet seems to work on several fronts — tackling several age-related diseases, which tend to occur together in later life. Research shows that those who followed the Mediterranean dietary patterns reduced their risk of cardiovascular disease, type 2 diabetes, certain cancers and brain diseases, all at the same time, which makes the diet particularly valuable for older adults.[\[14\]](https://pubmed.ncbi.nlm.nih.gov/28488692/?ref=alphabetguides.com) The practical beauty of the Mediterranean diet lies in its sustainability. Unlike restrictive diets, we know people can maintain the diet for decades, precisely what's needed for long-term health benefits. Even “moderate adherence” can provide health benefits, meaning the diet doesn’t have to be followed to the letter 100% of the time. But the closer the diet is [followed](https://www.alphabetguides.com/mediterranean-diet-meal-plan/), the better! The focus should be on the overall pattern: [abundant vegetables](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/), fruits, legumes, and whole grains; generous use of extra virgin olive oil; regular intake of fish; moderate amounts of dairy and poultry; and limited red meat and processed foods. The emphasis on flavourful, whole foods, shared meals, and culinary pleasure means adherence rates remain high, even in people who live far from the Mediterranean. ![Group of older adults playing boules.](https://images.unsplash.com/photo-1593845299589-ca56b999d6a1?crop=entropy&cs=tinysrgb&fit=max&fm=jpg&ixid=M3wxMTc3M3wwfDF8c2VhcmNofDd8fGJvdWxlcyUyMHBsYXlpbmd8ZW58MHx8fHwxNzgzNDAzNzk3fDA&ixlib=rb-4.1.0&q=80&w=2000) --- ## #5\.

Poor sleep and stress further disrupt your appetite, making weight loss more challenging. You’ve probably heard of having a “loss of appetite” or “controlling your appetite”, but far from simple hunger pangs, appetite is determined by your hormones, your brain wiring and [your environmen](https://www.alphabetguides.com/fat-loss-beyond-diet-exercise/)t. Your appetite originally evolved to maintain survival; to ensure you have enough energy and nutrients to keep you alive. However, it now operates in a "food-abundant" world. ## What is an "appetite"? Appetite covers two separate (but interconnected) parts that control your eating behaviour: 1. **"Hunger"**, which is the physiological need for food, is driven by energy depletion and hormonal signals. 2. **"Satiation"**, which tells you when to stop eating. Think of it as the “I’m full” signal. “Satiety” signals maintain that feeling of fullness between meals and determine when you'll next seek food. So you’re either full or hungry, or somewhere in between. Seems quite obvious, but these two systems work together through complex processes (called “feedback loops”). The feedback loops involve your brain, digestive system, fat tissue, and several other [hormones](https://www.alphabetguides.com/tag/hormones/). Achieving (and maintaining) a healthy body weight requires addressing not just when to start eating, but also when to stop and maintain satiety levels over time.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/17542673/?ref=alphabetguides.com) ## Your brain: the central controller of your appetite The part of the [brain](https://www.alphabetguides.com/tag/brain-health/) principally responsible for your appetite is the “hypothalamus”. Its role is to process the signals sent from different parts of your body and to coordinate the response (i.e., to eat or not to eat). It contains two parts: one that stimulates appetite and one that suppresses it. Both of these parts get their information from your hormones, the nutrient levels in the blood, and other parts of your brain. They process all this information together before adjusting your hunger and satiety settings. This entire system is basically done automatically for you and operates below “conscious awareness”.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/22238401/?ref=alphabetguides.com) --- ## How appetite hormones work Multiple hormones regulate your appetite. For instance: - “**Ghrelin**” hormone, produced by the stomach, increases before meals and stimulates hunger, but falls very quickly once you start eating. - **Leptin** is an appetite-suppressing hormone that is released from the fat tissue itself. Leptin doesn’t change as quickly as ghrelin, so it gives a longer-term perspective on how well you’re maintaining your appetite and energy levels. - Glucagon-like peptide-1 (**GLP-1**), Gastric Inhibitory Polypeptide (**GIP**), Peptide YY (**PYY**) and Cholecystokinin (**CCK**) are four more “I’m full” (satiety) hormones, which are released by your intestines after you eat food. - **Neuropeptide Y** (made in the brain) and [**cortisol**](https://www.alphabetguides.com/what-is-cortisol/) (made in the adrenal glands) are two more "orexigenic" hormones that increase your appetite. - **Insulin**, in addition to controlling your blood sugar levels, also has a critical role in regulating appetite. All these different hormones have to work together and require precise timing and sensitivity to maintain a healthy appetite. --- ## How appetite affects weight loss and body weight Small disruptions in some of the processes that regulate your appetite can lead to changes in your body weight. For instance, when you start to lose fat, your body’s appetite systems actively defend against it by increasing the release of the “hunger hormones” and decreasing the release of the “satiety hormones”. Scientists call this response “metabolic adaptation”, and it partially explains why [weight loss](https://www.alphabetguides.com/tag/fat-loss/) programmes are often not as straightforward as they sound. Whilst it may seem like it *prima facie*, your body *isn’t* trying to sabotage your new [diet](https://www.alphabetguides.com/fat-loss-diets/). It actually thinks it's protecting you. Your body doesn’t like sudden changes, irrespective of whether you need them or not. Losing a lot of weight, very quickly, can trick your body into thinking that you're starving. So it then initiates a hard-wired “starvation response”, which sends signals to increase food intake in the hope that you can restore the energy reserves. Understanding this physiological reality can help explain why sustainable weight loss requires working with, rather than against, your own appetite.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/22029981/?ref=alphabetguides.com) ## What derails your appetite Your "food environment" can override natural appetite regulation processes, exploiting its natural vulnerabilities. [Ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/) high in sugar, fat, and salt create eating behaviour(s) that bypass your normal satiety signals, directly stimulating the brain's reward system.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/15998351/?ref=alphabetguides.com) The near-unlimited availability and variety of food on offer can overwhelm our natural systems that control our appetites, which were designed for more food-scarce times. Historically, having a good appetite and a high motivation to find food was an advantageous evolutionary trait. However, today it is less of an advantage when thousands of different food options are [available](https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/) in unlimited amounts with just a few clicks. Sleep and large amounts of stress can also disrupt normal appetite regulation. Just one poor night’s [sleep](https://www.alphabetguides.com/tag/sleep/) can increase your appetite. Too much stress can also increase hunger and shift preferences towards high-calorie, highly processed “junk” foods. There’s also a negative feedback loop here where more stress leads to poorer sleep, and more poor sleep leads to more stress, and so on and so on, which exacerbates the problem further. Lastly, there is also an important distinction to make between "physiological" hunger (i.e., what food your body *actually* needs) and psychological" hunger (i.e., what food your brain *thinks* your body needs).[\[5\]](https://pubmed.ncbi.nlm.nih.gov/26779321/?ref=alphabetguides.com) These are normally misaligned in people who struggle to control their body weight, and can be difficult to correct for some people. Scientists call this “metabolic scarring”. Therefore, rather than fighting your individual appetite profile, try to work with it where possible and tip the odds in [your favour](https://www.alphabetguides.com/volumetrics-diet/). --- #### Sources 1.

For growth, aim for at least 1.2 g/kg/day spread throughout the day, from high-quality sources. Amino acids are what [muscle](https://www.alphabetguides.com/tag/muscle/) is made of. The basic units of muscle are just chains of these tiny molecules linked together. When these amino acid chains get long enough and start to fold up in different shapes, that's called a protein. The body uses these proteins to repair old muscle and build new muscle. Think of amino acids as the bricks in your muscle-building house. Without enough bricks, no matter how skilled the builders are or how hard they work, you can't build a home. Likewise, without enough amino acids, your muscles can’t grow. When you eat protein, whether it’s from chicken, peas, yoghurt, or fish, your body breaks it down into amino acids. Then, your cells rebuild new proteins from the amino acids that are used to repair and grow muscle.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/19301095/?ref=alphabetguides.com) [Plants ](https://www.alphabetguides.com/plant-based-protein/)absorb nitrogen from the soil and make amino acids. Animals eat plants and convert them into muscle. Humans then eat the animals (or plants), break these proteins down into amino acids, and then rebuild them. Just twenty amino acids are used to make protein. Nine of these are what are called “essential" amino acids (EAA), as your body cannot make them, so you have to get them from your diet. The other 11 are non-essential amino acids (NEAA), which your body can produce as needed. Both are important. However, EAAs are a bit more important for muscle growth. ## The building blocks of muscle Amino acids are also the main source of nitrogen in the body, with each amino acid containing at least one nitrogen atom. Consequently, scientists have used a technique known as “nitrogen balance” to estimate the amount of protein you need and to assess whether the body is gaining muscle (positive “nitrogen balance”) or losing muscle (negative “nitrogen balance”). The process of building muscle from amino acids is called “Muscle Protein Synthesis” (MPS) — this biological process is the engine of muscle growth. To trigger it, you require both a "stimulus" (like exercise, nutrients, or [hormones](https://www.alphabetguides.com/testosterone-and-muscle-growth/)) and an adequate supply of amino acids, especially EAAs, with leucine playing a key role.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/12368421/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/24791918/?ref=alphabetguides.com) While carbohydrates and fats get some attention, when it comes to muscle growth, protein and amino acids are the most important things. Getting [enough](https://www.alphabetguides.com/high-protein-diet/) high-quality protein day-to-day is one of the most important things you can do to support strength, recovery, and performance. However, not all amino acids, or even all EAAs, are equal in promoting muscle growth. --- #### Amino Acids and Their Function These are the physiological roles of different amino acids outside of muscle repair and growth. The nine Essential amino acids are ****bolded**. - Alanine: Energy, brain health, immune health, detoxification - Arginine: Immune health, circulation, detoxification - Asparagine: Gene control, immune health, nerve health - Aspartic acid: Energy, brain health, gene building, detoxification - Cysteine: Protein structure, cell protection, and cell communication - Glutamic acid: Energy, brain health, immune health, detoxification - Glutamine: Immune health, energy, inflammation, detoxification - Glycine: Nerve health, function, gene building, oxygen transport - ****Histidine:** Oxygen transport, oxidative stress, immune health, gut health - ****Isoleucine:** Energy, amino acid building - ****Leucine:** Energy, Gene Expression, immune health - ****Lysine:** Immune health, collagen support - ****Methionine:** Heart health, gene regulation, energy, antioxidant - ****Phenylalanine:** Brain health, circulation - Proline: Collagen, cell maintenance, immune health, stress response - Serine: Gene building, energy, and brain health - ****Theonine:** Gut Health, immune health, energy - ****Tryptophan:** Mood, inflammation control, immune health, energy - Tyrosine: Brain health, immune health, energy, and antioxidant - ****Valine:** Muscle energy, amino acid building --- ## What amino acids matter All nine of the EAAs must come from your diet in adequate amounts. However, among these, three are called “Branched-Chain Amino Acids” (BCAAs) — leucine, isoleucine, and valine. Out of the three BCAAs, leucine is known to be particularly important for “flipping the switch”, turning on MPS. That’s why high-quality protein sources like eggs, dairy, and meat are generally considered “complete” proteins, as they deliver all nine EAAs in the right amounts. Whereas if one or more of the EAAs are missing, or not provided in adequate amounts, the protein source is typically considered “incomplete”.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/22594765/?ref=alphabetguides.com) Animal proteins are complete proteins with balanced profiles. Whereas [plant proteins](https://www.alphabetguides.com/plant-based-protein/) usually have 1 or more EAAs missing. Meaning that they need to be obtained from elsewhere. #### Do you need to take BCAA supplements? BCAA supplements alone do not outperform normal high-quality protein sources, which provide all the EAAs needed for muscle repair and growth. So if you’re already meeting your protein requirements, additional BCAA supplements are probably unnecessary.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/24791918/?ref=alphabetguides.com) ## Is amino acid timing important? Your body is continuously breaking down and rebuilding muscle, about 1–2% every day. This “turnover” of muscle tissue is what allows it to adapt to new challenges, like when you start a [weightlifting program](https://www.alphabetguides.com/minimalist-muscle-growth/). If your muscles weren't able to tear down and rebuild themselves, the adaptation process would be much slower.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/28919842/?ref=alphabetguides.com) Therefore, it is generally advised to eat several [high-quality protein-rich meals](https://www.alphabetguides.com/plant-based-diet-meal-plan/) or supplements spaced throughout the day to support muscle building. Timing is a well-debated topic, but consuming enough protein at each meal (with some protein at snacks too) is an effective strategy. The generalrecommendation for the amount of protein you eat is about **0.8 g/kg/day** minimum for most people, **1.2-2.0 g/kg/day** for those who are training for hypertrophy, and *possibly* higher for high-performance athletes who are training a lot. Aim for *at least* 20 g of high-quality “complete” protein per meal to maximally stimulate muscle growth.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/21289204/?ref=alphabetguides.com) --- ## Leucine Among the twenty amino acids, one stands apart as the master regulator of muscle growth: leucine. It is not only a "building block" for muscle like the other EAAs, but it also acts as a hormone-like “trigger” that activates muscle growth processes. _This post is for subscribers only._ ### A Practical Guide to Starting the Mediterranean Diet URL: https://www.alphabetguides.com/mediterranean-diet-guide/ Last updated: 2026-09-03T08:20:06.000Z ## About This Series This series aims to introduce you to the Mediterranean Lifestyle: the [diet](https://www.alphabetguides.com/tag/mediterraneandiet/), movement, leisure time, and social life.

Research shows people following a [Mediterranean lifestyle](https://www.alphabetguides.com/mediterranean-culture/) have lower disease risk, longer life expectancies and quality of life — all while *enjoying* what they eat! In this series, we’ll focus on: what they eat, how they move, how they rest, and how they connect. ### First Task: The Mediterranean Diet Foods Before we get into the details, we need to set a baseline. Take a few minutes to answer yes or no to the following questions: 1. I eat 5+ servings of vegetables a day. 2. I eat fish or seafood 2+ times a week. 3. I use olive oil as my primary source of fat. 4. I sit down for meals with others 3+ times a week (no screens). 5. I eat red meat or processed meats less than twice a week. 6. I eat legumes 2+ times a week. 7. I eat sweets or processed foods less than twice a week. 8. I do something physically active for at least 30 minutes a day. 9. I go out to socialise with people at least 2 hours a week. 10. I sleep at least 6 hours a day (including naps and siestas). You get 1 point for a “YES” and 0 points for a “NO”. Calculate and record your total score out of 10\. You can redo this test after 30 days of following the diet. Use it as a checklist if you're into that sort of thing. ### Second Task: Build your Mediterranean pantry You can't cook Mediterranean meals without Mediterranean staples. Start gathering these essentials: read our blog post on [building your pantry for the Mediterranean diet](https://www.alphabetguides.com/7-pantry-essentials-for-the-mediterranean-diet/). ### Third Task: Beginning the Mediterranean diet Visit a grocery store or market this week. Buy and stock up your Mediterranean pantry essentials, ready to start. Take a photo of your pantry or kitchen cupboard, before and after — you'll want to remember where you started. --- ## Lesson 2: The Mediterranean Diet Vegetables ![Bunch of vegetables on a supermarket shelf.](https://images.unsplash.com/photo-1542838132-92c53300491e?crop=entropy&cs=tinysrgb&fit=max&fm=jpg&ixid=M3wxMTc3M3wwfDF8c2VhcmNofDE2fHx2ZWdldGFibGVzfGVufDB8fHx8MTc4MzI2ODgyNHww&ixlib=rb-4.1.0&q=80&w=2000) Traditionally, Mediterraneans have eaten 6–8 servings of vegetables *a day*. Today, most people eat less than 2! This gap explains a lot about why they live longer, healthier lives. ### Why vegetables are non-negotiable Research tracking over 2 million people found that consuming approximately 10 servings of vegetables and fruits daily (with vegetables being the majority) reduced [cardiovascular disease](https://www.alphabetguides.com/tag/heart-health/), cancer rates and risk of death.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5837313/?ref=alphabetguides.com) Here’s the secret: nobody counts to 10 servings. Mediterraneans don’t either. They just made vegetables the main part of every meal. Instead of thinking “side dish”, think “foundation”. For [breakfast](https://www.alphabetguides.com/mediterranean-breakfast-ideas/), add spinach to eggs, top toast with tomatoes, or add berries to yoghurt. Change your lunch from a sandwich to a [large salad](https://www.alphabetguides.com/mediterranean-salads/). For dinner, fill half your plate with vegetables first, before adding anything else. Snack on hummus or cold roast veg, not chips. For the next 3 days, fill [half your plate](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/) with vegetables at lunch and dinner. That's it. No counting. Don't change anything else just yet. ### 3 quick and easy Mediterranean vegetable recipes 1. **Greek-style roasted vegetables:** Zucchini, eggplant, peppers, and tomatoes tossed with olive oil, oregano, and garlic. Roast at 400°F (200°C) for 30 minutes. Eat warm, eat it with pasta, toss it in a salad, blend it into a soup, put it on whole-grain bread for lunch, or put it on top of your scrambled eggs for breakfast. 2. **Simple arugula salad:** Peppery arugula, cherry tomatoes, shaved parmesan, olive oil, lemon juice, black pepper. It takes 3 minutes to make. You can add some cooked chicken, tuna or other canned fish if you want to make a meal out of it. 3. **Tomato-cucumber salad:** Chunked tomatoes and cucumbers, red onion, olive oil, red wine vinegar, fresh basil or mint. Let it sit for 10 minutes before eating. Add feta cheese and dip the bread in the juices to make it into a meal. ### Tips - Mediterraneans don't steam or boil everything. They cook vegetables in olive oil, which actually increases absorption of fat-soluble vitamins. Don't fear fat — embrace it.[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC9386289/?ref=alphabetguides.com) - Keep pre-washed salad greens and cherry tomatoes on hand. Roast a big tray of vegetables on Sunday for the week. Frozen vegetables absolutely count — use them! ### Tasks 1. Buy three different [coloured vegetables](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/) at your next shop (more colours = more nutrients). 2. Try ONE of the vegetable dishes mentioned above. 3. Follow “The Half-Plate Rule” for the next 3 days. --- ## Lesson 3: liquid gold — mastering olive oil on the Mediterranean diet ![A person pouring olive into a pot.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1688228246800-2bac4342cb88.jpeg) Extra virgin olive oil (EVOO) contains powerful [polyphenols](https://www.alphabetguides.com/superfood-olive-oil/): plant compounds with anti-inflammatory effects comparable to ibuprofen3. These polyphenols reduce inflammation, lower blood pressure, improve cholesterol profiles, help protect brain health, fight chronic disease and ageing.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/16136122/?ref=alphabetguides.com) But the polyphenols degrade with heat, light, processing, and time. That's why the quality and freshness of the olive oil matter. Look for a dark glass bottle or tin (light degrades polyphenols), a harvest date within the past year (fresher = more polyphenols), a single-origin source, estate bottled or certification seals. ### The taste test Quality EVOO should have a peppery, slightly bitter taste that tickles your throat. That sensation? It's the polyphenols. If your oil tastes bland or greasy, it's a good sign that it probably doesn’t contain as many of them. - **Myth buster:** Heating EVOO destroys its health benefits and creates harmful compounds. - **Truth:** EVOO is stable at normal cooking temperatures (under 200°C or 390°F). Its antioxidants and healthy fats remain intact when you sauté or roast, making it safe and beneficial for everyday cooking. ### “The 4-Tablespoon Goal” Mediterraneans don't measure olive oil in teaspoons — they just use it generously. Your goal this week: consume approximately 4 tablespoons of EVOO *a day*. - For breakfast, drizzle a tablespoon on your tomato toast or cook your eggs in it instead of butter. - For lunch, add a tablespoon to your salad with lemon juice and herbs. - For dinner, sauté your vegetables in it and drizzle it over your soups, stews, legumes, grains, or fish. **1-minute** [**Recipe**](https://www.alphabetguides.com/tag/recipes/) **— EVOO dressing:** Mix 1 part "acid" (like lemon juice or red wine vinegar) with any, or as many, Mediterranean flavours you want (e.g., herbs, spices, garlic, finely diced onions or shallot, Dijon mustard or honey); then add 3 parts EVOO to make the dressing. **Budget tip:** One bottle of high-quality EVOO ($10-20) used properly over a month costs less than a daily coffee run, and the health benefits are exponentially higher. ### Tasks 1. Aim for 4 tablespoons of EVOO a day total. 2. Replace all other fats with EVOO (e.g., butter, margarine, other cooking oils). 3. Upgrade your olive oil; invest in one quality bottle of EVOO for finishing dishes with. --- ## Lesson 4: The protein mistake most people make ![Boiled egg with vegetables and tomatoes on blue plate.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1490645935967-10de6ba17061.jpeg) Question: What's the primary protein source in the [Mediterranean diet](https://www.alphabetguides.com/mediterranean-diet-review/)? If you answered “fish”, you're half right. The true answer: legumes. Beans, lentils, and chickpeas form the protein foundation, with fish appearing about two to three times a week, some poultry, moderate dairy, and red meat maybe once or twice monthly (if that). You don't need to eliminate it, but make red meat occasional, not habitual. Researchers found that replacing red meat with legumes and other Mediterranean proteins reduced cardiovascular disease, cancer and all-cause mortality.[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3712342/?ref=alphabetguides.com) **Why does protein source matter more than protein amount?** All proteins provide [amino acids](https://www.alphabetguides.com/amino-acids-muscle/), but the package they come in also matters: [plant proteins](https://www.alphabetguides.com/plant-based-protein/) also come with fibre, phytonutrients and no saturated fat. Fish provide omega-3 fatty acids that reduce inflammation and protect your brain. ### Task Replace at least 2 meat-based meals with Mediterranean protein alternatives this week. Try to prioritise legumes and oily fish (like salmon, sardines, mackerel, or anchovies).Read our post on [cheap high-protein](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/) Mediterranean dishes. Why not try one! ### Other Mediterranean Protein Ideas: **Legumes (3+ servings a week):** White bean and kale soup; chickpea salad; lentil stew; hummus with falafel and pita bread. **Fish (2+ servings a week):** Steamed salmon with lemon and herbs; sardines on toast; Baked cod with tomatoes, olives, and capers. **Eggs and poultry (2–4 times a week):** Omelettes and frittatas loaded with vegetables; Greek-style lemon-herb roast chicken; eggs fried in olive oil with wilted greens. **Low-fat dairy (small amount every day):** Greek yoghurt with fruit and nuts, finish salads with feta or Parmesan, stewed seasonal fruits with ricotta or cottage cheese and honey. ### Tasks 1. Swap these meals for red meats if you eat them regularly. 2. Buy and cook fish (ideally oily species) at least once this week. 3. Plan two [legume-based meals](https://www.alphabetguides.com/plant-based-diet-meal-plan/) this week. --- ## Lesson 5: The dining habit that improves health ![A group of people sitting at a long table.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1670899460364-ebc917bac09a.jpeg) Here's something that might surprise you: The health benefits of eating with others rival the benefits of quitting smoking.

If you’re tired of conflicting advice, unnecessary complexity, or fads that don’t work, this course is for you. We'll explain how muscle growth actually works. Each lesson builds on the last, covering training structure, recovery, progression, and the principles that drive long-term gains. Everything is evidence-based and drawn from decades of research and experience. By the end, you’ll have the knowledge to create, evaluate, or adjust any resistance training programme with confidence. The content of this course reflects current consensus from exercise science research, where available — it's backed by decades of research and practice. ### What’s included - How resistance training actually works: “The Physiology” - How to structure resistance training sessions - Recovery, nutrition, and a few other important things - How to progress safely and sustainably over time ### What we avoid This isn't a workout program with specific exercises or training schedules. It's educational content that’ll help you understand why programs work, and why they don't. Once you know these principles, you'll be equipped to evaluate resistance training programmes and start tailoring it your own needs. If you want more detailed and structured information, we have a whole [resource hub](https://www.alphabetguides.com/tag/exercise/) on exercise (which includes a lot on resistance training). ### How to use this course Each lesson in this series is a quick 5-minute read, with a small task at the end of each one. These tasks aren't strictly necessary, but doing them will help crystallise your understanding. ### On individual responses The principles in this series apply broadly, but individual responses vary. Your age, training experience, genetics, lifestyle, and dozens of other factors will influence how your body responds to training. The ranges and recommendations provided are starting points, *not* rigid prescriptions. ### Your task for today: Before reading further, take a moment to think about why you're interested in starting resistance training and what brought you here. Understanding your own motivation (even if it's just mere curiosity) can help you extract more value from the information ahead. --- ## Lesson 1: The physiology of resistance training ![Dna double helix render on blue.](https://images.unsplash.com/photo-1628595351029-c2bf17511435?crop=entropy&cs=tinysrgb&fit=max&fm=jpg&ixid=M3wxMTc3M3wwfDF8c2VhcmNofDd8fGNlbGx8ZW58MHx8fHwxNzgzMjYxMzM3fDA&ixlib=rb-4.1.0&q=80&w=2000) Muscle growth *doesn't* happen during training. This might seem counterintuitive, but understanding this point is essential to everything that follows. When you lift weights, you're not building [muscle](https://www.alphabetguides.com/tag/muscle/) — you're creating the conditions that will later cause muscle to grow. The actual growth processes occur *between* training sessions, while you're recovering, when your body adapts to the stress you've placed on it. ### The three signals for growth Researchers have identified three primary mechanisms that signal your body to build muscle: 1. **Mechanical tension** is the force experienced by your [muscle fibres](https://www.alphabetguides.com/muscle-fibre-types/) when they contract against a resistance (e.g., a dumbbell or barbell). This is the most important signal by far. When you lift a weight, your muscle fibres generate tension to move that load. This tension then triggers a wave of cellular responses that stimulate muscle growth. 2. **Metabolic stress** occurs when muscles work hard enough to accumulate metabolic byproducts like lactate and hydrogen ions. This is the “burning” sensation you feel during high-repetition sets. It is thought to contribute to the growth signal, though it's nowhere near as important as the mechanical tension. In fact, some scientists think that metabolic by-products don’t matter at all.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/32830552/?ref=alphabetguides.com) 3. **Muscle damage** refers to microscopic tears in muscle fibres caused by training. While some damage may contribute to growth, it's not necessary to feel sore after every session. In fact, [excessive soreness](https://www.alphabetguides.com/doms/) can interfere with training consistency. So, the aim of the training session should *not* be to “damage” your muscles.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/21270317/?ref=alphabetguides.com) ### The adaptation process Here's what happens after you train: 1. Your body recognises that the stress you imposed was challenging. 2. In response, it initiates repair and growth processes to handle similar stress in the future better. 3. A process called muscle protein synthesis increases, where new contractile proteins are added to existing fibres 4. Over time, these new proteins accumulate, causing muscles to grow larger and stronger. This is referred to as an “adaptation”. Your body is essentially saying: “That was difficult. If I am going to have to lift these weights regularly, I should build more capacity so next time it's easier”. It is a hard-wired protective mechanism that's designed to prevent your muscles (and connective tissues) from tearing. ### Why effort matters For these signals to be strong enough to trigger growth, your training must be sufficiently challenging. Light weights moved casually don't create enough mechanical tension to signal the muscle to adapt. This is why training "intensity" (i.e., how hard you're working relative to your maximum capacity) [matters a lot](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/). Current evidence suggests that training within a few repetitions of muscular failure (i.e., the point where you cannot complete another repetition with good form) maximises the growth response. You don't need to reach complete failure on every set, but you should finish most working sets feeling like you could only manage a few more reps.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/33497853/?ref=alphabetguides.com) ### The efficiency spectrum Muscle growth can occur across a broad range of training loads (i.e., how much weight you’re lifting). Light weights for high repetitions to heavy weights for low repetitions stimulate growth, provided your effort level is high. However, moderate loads (roughly 60-80% of your maximum for a single repetition) appear most *efficient* for most people. This typically corresponds to sets of six to fifteen reps per set. ### What doesn't work Training with very light loads while stopping far from failure will produce minimal growth and is inefficient. Your body has no reason to adapt if the stress is easily manageable. Similarly, training with extremely heavy loads for very few repetitions primarily develops maximal ["neuromuscular" strength](https://www.alphabetguides.com/muscle-adaptation/) rather than muscle size, though there's certainly overlap. Your muscles will still grow as long as the effort is high. ### The task The next time you're at the gym, notice the difference between sets performed with genuine effort versus those performed casually. Pay attention to how challenging the final few repetitions feel. To train to, or close to, failure with high effort, you need to know what failure and effort feel like. For beginners, you will want to do this on a machine rather than with free weights (that can come later!) --- ## Lesson 2: Building an effective training session ![Open monthly planner on wooden desk.](https://images.unsplash.com/photo-1435527173128-983b87201f4d?crop=entropy&cs=tinysrgb&fit=max&fm=jpg&ixid=M3wxMTc3M3wwfDF8c2VhcmNofDJ8fHBsYW4lMjBjYWxlbmRhcnxlbnwwfHx8fDE3ODMyNjE0Mzd8MA&ixlib=rb-4.1.0&q=80&w=2000) Now that you understand the mechanisms behind muscle growth and what to aim for, we can discuss how to structure individual training sessions to optimise growth signals. ### The warm-up: you need less than you think The purpose of warming up is to prepare your body for the work ahead. Its aim should be to raise your muscle temperature, rehearse the movement you are about to do, and mentally prepare yourself for a high level of effort. However, the warm-up doesn't need to be elaborate or fancy. For lighter training sessions, a general warm-up (five to ten minutes of light movement on the treadmill or a bike) provides some performance benefits, but there are better ways to do it. What does help is a specific warm-up: performing one or two lighter sets of the actual exercise you're about to do. This rehearses the movement "pattern" and prepares the same muscles you're about to use. If you're lifting heavy loads (above 80% of your maximum), an exercise-specific warm-up with progressively heavier weights, “a ramp up” is needed. For lighter or moderate loads, one lighter warm-up set is normally fine. ### On "working" sets After warming up, you'll perform your “working sets”. These are the challenging sets performed at high effort that actually stimulate growth. This is where the principles from the last lesson apply. Research suggests that performing multiple sets per exercise is more effective than single sets. The current evidence points to three to ten working sets *per* muscle group *per* session as an effective range. This might be distributed across one to three different exercises targeting that muscle.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/20300012/?ref=alphabetguides.com) For example, if training your chest, you might perform two sets of a barbell press followed by two sets of dips; that's four total working sets for that muscle group. ### Rest periods: longer than you think The time between sets matters for maintaining performance "quality". Shorter rest periods (under 60 seconds) create more metabolic stress, and you’ll definitely finish workouts faster. However, short rest periods can compromise your ability to maintain your load and repetition targets across all sets. Longer rest periods (two to three minutes) allow for more complete recovery, allowing you to lift heavier loads or complete more repetitions at a fixed load. Since mechanical tension is the primary driver of growth, maintaining performance across sets should be your main aim. Current evidence suggests rest periods of one to three minutes represent a reasonable compromise between time efficiency and performance maintenance. If you're lifting particularly heavy loads (over 90% 1RM) or performing demanding compound movements, err toward the longer end of this range — and possibly longer.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/19691365/?ref=alphabetguides.com) ### Exercise selection: compound movements first Exercises can be classified as "compound" (i.e., involving multiple joints and muscle groups) or "isolation" (i.e., targeting a single muscle group around one joint). Example: a squat is a compound movement involving the hips, knees, and ankles. Whereas a leg extension is an isolation movement focusing primarily on the quadriceps. Compound movements are generally more [time-efficient](https://www.alphabetguides.com/cut-your-training-time/) because they work multiple muscle groups at the same time. They also allow you to handle heavier loads, creating substantial mechanical tension and a more reflective experience of the movements you do in everyday life. For these reasons, compound movements typically form the foundation of the most efficient training programs. Isolation exercises can add value to any workout by targeting specific muscles, but they're not essential for everyone, particularly beginners or those with limited time. ### Training frequency: hit multiple muscles multiple times How you distribute your weekly training matters. Training each muscle group two or more times per week appears superior to once-weekly training for muscle growth. This allows you to spread your total weekly volume across multiple sessions, maintaining higher quality and effort on each set.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/27102172/?ref=alphabetguides.com) This might look like two to three full-body sessions per week, or one upper-body and one lower-body session performed once or twice a week (two to four total sessions), or a push-pull-legs (PPL) “split” performed once or twice-weekly (three to six total sessions). The key principle is that each major muscle group is trained at least twice a week. ### Session volume: don't overdo it While you need sufficient volume to stimulate growth, excessively long sessions become counterproductive. Quality deteriorates as you become more fatigued, and the final bunch of sets in an extremely long session provide diminishing returns for growth.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/12351337/?ref=alphabetguides.com) For most people, effective training sessions last 45 to 90 minutes total, including warm-up and rest periods. If your sessions regularly exceed this, consider whether you're performing too many exercises or sets per session. ### Your task If you’re currently training or plan to start soon, sketch out a basic weekly schedule: which days will you train, and which muscle groups will you work on each day? Ensure each major muscle group is trained at least twice per week. Don't worry about specific exercises yet — just the overall structure. There is nothing wrong with two full-body sessions a week.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/41843416/?ref=alphabetguides.com) --- ## Lesson 3: What happens between training sessions ![Topless man in black shorts holding cooked food.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1587996597484-04743eeb56b4.jpeg) The work you do in the gym creates the stimulus for growth. What you do outside the gym determines whether that growth actually occurs. _This post is for subscribers only._ ### Body Recomposition: A 5-Part Series URL: https://www.alphabetguides.com/body-recomposition-series/ Last updated: 2026-10-02T14:21:25.000Z ## About this series Ignore the scales and understand how to lose fat and build muscle at the same time. Whether you're new to training and nutrition or not, this series of articles aims to provide clarity. In this series, we'll cover training, nutrition, recovery, and better ways to measure progress. Each lesson contains evidence-based advice and resources; no calorie counting, no rigid meal plans, no unrealistic promises. If you're confused by conflicting advice (because there's a lot out there), frustrated if or when the scale doesn't move despite the hard work, or unsure whether to focus on fat loss first or muscle growth? This series of articles aims to clear up confusion. By the end of it, you'll understand the essential elements of body "recomposition" and how to measure what actually matters. ### Contents 1.

But that single figure hides something more important — what your body is actually made of. Body recomposition means losing fat and gaining [muscle](https://www.alphabetguides.com/tag/muscle/) at the *same time*. So, rather than just making your body smaller, you're changing what it's made up of (i.e., its “composition” or body composition). Two people can weigh the same weight but look completely different and have vastly different health prospects depending on how much muscle and fat they carry. Here's what makes “recomposition” different from typical weight loss: your body weight includes fat, muscle, bone, organs, water, and connective tissue. When you step on a scale, you're measuring all of these together. Body composition refers to the relative proportions of the different tissues, particularly the ratio of fat to everything else. ### Why this matters The person with more muscle and less fat generally has better health, greater functional capacity in everyday life, and lower disease risk — even if they’re the same body weight as someone who has less muscle and more fat. For years, conventional thinking suggested you *couldn't* build muscle and lose fat simultaneously. The logic seemed sound: building new tissue requires extra energy ("surplus"), while burning fat requires an energy deficit. How could both happen at the same time? The confusion comes from treating the body as a single, unified system. In reality, muscle tissue and fat tissue operate independently from each other and respond to different signals. Fat tissue stores and releases energy. Muscle is made of proteins that contract to produce force and move you around. They respond differently to different hormones, nutrients, environments, and changes on different timescales. Under the right conditions, such as adequate [protein intake](https://www.alphabetguides.com/plant-based-protein/), resistance training, and a moderate energy deficit, your body can break down fat for energy while building muscle at the same time. Think of protein as the building material and the rest of [your calories](https://www.alphabetguides.com/eat-to-lose-fat/) (from fat and carbohydrate) for energy. You need bricks to build a house, not just fuel for the builders. ### Can anyone do body recomposition? Body recomposition isn't equally accessible or achievable for everyone. Those new to resistance training typically see the most dramatic changes, as do people who're carrying more body fat to start with. Age and training history matter too, but this doesn't mean older and leaner people can't achieve recomposition — they absolutely can, though the changes may be more modest and hard-fought. Over time, there'll likely be a point where dedicating specific periods to *either* building muscle or losing fat becomes more efficient than doing both at the same time. Some people may also prefer to concentrate on one thing at a time (i.e., “bulk” or “cut”), or focus on building more muscle (while losing a bit of fat), or losing a large amount of fat while simply maintaining their muscle mass. ### What sustainable body recomposition isn't! Body recomposition is not a rapid transformation. It's a slow, moderate, sustained process, requiring months of consistent effort. It won't produce the dramatic scale drops that [crash diets](https://www.alphabetguides.com/crash-diet/) promise. In fact, your total weight might barely change as you gain muscle and lose fat in roughly equal amounts. This approach also requires alignment of three distinct elements: 1. **Exercise** that signals your body to maintain or build muscle. 2. **Nutrition** that provides adequate protein and a moderate energy deficit. 3. **Recovery** through sleep and managing stress. Optimising one while neglecting others won't work. Over the series, we'll cover each of these components in detail — the specific training approach needed, nutritional requirements, recovery principles, and how to actually measure progress when the scale doesn't tell the full story. --- ## Lesson 2: Resistance training for recomposition ![Man in the gym preparing for a deadlift.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1605490855119-94921710a47f.jpeg) Your body is efficient at managing its resources. Muscle is “metabolically expensive”, meaning it requires a lot of energy to build, maintain, and repair, even when you're not using it. From an evolutionary perspective, carrying unused muscle is wasteful. This is why your body will break it down when it's not in use, particularly when your energy reserves are low (i.e., when you're in a calorie deficit). This isn't punishment for skipping workouts — it's your body allocating its resources more efficiently. The most powerful signal for building muscle is mechanical tension (from muscle “contractions”), which is generated most efficiently through resistance training. Nothing else can substitute for it. ### How resistance training actually works When you lift a weight heavy enough to challenge your muscles, you create “mechanical tension” in your muscles, similar to when you flex and your muscles become tense. When you “overload” your muscle by lifting until it's either too heavy to move or you're too fatigued to continue lifting, your body recognises this as a signal — that adaptation is needed. In response, your [individual muscle cells](https://www.alphabetguides.com/muscle-fibre-types/) begin producing more protein than they normally do. This process continues for up to 48 hours after training (assuming you're consuming adequate dietary protein). Resistance training provides the signal; dietary protein provides the raw materials. Despite commonly held beliefs, you're *not* just simply repairing damaged tissue and restoring it to its previous state. You're rebuilding it to be larger and stronger, making it more capable and prepared to handle similar mechanical stress in the future. All of these changes happen at the cellular level, so you won't notice measurable growth after a single session. But over weeks and months, these small adaptations accumulate into visible changes in muscle [strength and size](https://www.alphabetguides.com/muscle-adaptation/). ### Progressive overload: why newbie gains won't last forever Your body adapts to the demands placed on it. Once it successfully adapts to a given level of mechanical stress, that stimulus is no longer challenging enough to trigger further adaptation. This is why “progressive overload”, which means you gradually increase training demands over time, is essential for keeping growth going. This doesn't necessarily mean adding more weight to the bar every session, though that's the most common approach. You can also increase the number of repetitions, add sets, reduce rest periods, or improve your technique. Progressive overload is particularly important during body recomposition because maintaining or increasing training volume helps ensure your body prioritises keeping the muscle it has, even when your energy reserves are limited. The training signal *must* remain [strong enough](https://www.alphabetguides.com/back-to-basics-a-checklist-for-muscle-growth/) to convince your body that the muscle is worth keeping despite its high metabolic cost. ### Training during an energy deficit There's a persistent myth that you cannot build muscle while you're in an energy deficit; you can only maintain it at best. While an energy deficit *isn't* optimal for muscle growth, it doesn't mean that you *can’t* build muscle whatsoever. When you combine resistance training with adequate protein intake, muscle growth *can* happen. It's not as efficient as building muscle in a calorie surplus, but it remains possible. The size of the deficit matters — very large deficits exceeding 500 calories a day will impair both your capacity for muscle growth and your training quality. Smaller calorie deficits (less than 500 calories) are better. ### What about cardio? Aerobic exercise like walking, running, or cycling increases energy expenditure and can help create the energy deficit needed for fat loss. However, the muscle contractions during cardio are light, low-force, and repetitive. This doesn't challenge muscles the way heavy resistance does, so it doesn't generate meaningful, measurable muscle growth. This doesn't mean you should avoid cardio. It offers important [health benefits](https://www.alphabetguides.com/improve-your-vo2max/) and [supports fat loss](https://www.alphabetguides.com/exercise-fat-loss/). Just understand it's not a substitute for resistance training. For maximising both body recomposition and general health, you'll likely want to include *both* resistance training *and* cardio. ### How resistance training supports fat loss Beyond building muscle, resistance training offers several benefits that [support fat loss](https://www.alphabetguides.com/3-underrated-ways-to-lose-fat/). 1. Muscle is metabolically active, so increasing muscle mass raises your resting metabolic rate. Five extra kg of muscle will burn the energy equivalent of about two to three kg of fat over a year. 2. Resistance training also burns energy during the workout and for several days afterwards. 3. The more muscle you have and the stronger it becomes, the more work you can do during the training session, meaning you’ll burn more energy during your workout. 4. Trained muscle becomes *more* efficient at using fat for fuel, particularly during rest and lower-intensity activities. This promotes the fat-loss part of recomposition. ### Common training mistakes The most common error is doing too much too soon. More training isn't *always* better, especially when you're on a calorie-restricted diet. There's an optimal amount of training that maximises adaptation without impeding your recovery capacity. Another mistake is neglecting progressive overload — doing the same workouts with the same weights indefinitely. Without gradually increasing training demands, your body has no reason to continue adapting. Finally, many people avoid resistance training altogether, hoping that cardio and diet alone will reshape their bodies. However, without the mechanical tension signal from resistance training, your body has no reason to maintain muscle while you lose fat. --- ## Lesson 3: Nutrition for recomposition ![Topless man in black shorts holding cooked food.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1587996597484-04743eeb56b4.jpeg) [Nutrition recommendations](https://www.alphabetguides.com/muscle-fuel/) for body recomposition are challenging because you're asking your body to support two different processes at the same time, which are traditionally viewed as incompatible: [building new (muscle) tissue](https://www.alphabetguides.com/muscle-fuel/) while in an energy deficit. _This post is for subscribers only._ ### Boost Testosterone Naturally: A 10-Part Blueprint URL: https://www.alphabetguides.com/testosterone-blueprint/ Last updated: 2026-09-14T09:46:20.000Z ## About This Series Learn to optimise your testosterone with 10 lessons.

The expected outcomes for men with a misfiring testosterone system would be measurable improvements in their health, performance, mood and *possibly* testosterone levels within 3-6 months. --- ## Lesson 1: Your blood testosterone levels aren't everything ![A gloved hand holding a test tube filled with blood.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1639772823849-6efbd173043c.jpeg) Most men think about testosterone in the wrong way. They will fixate on a single blood test number: “total testosterone”. However, this number doesn't tell the whole story. Testosterone works in a "system", which is made up of three parts. ### 1.“Production” (how much you make) Your Leydig cells in the testes produce roughly 6-7 mg of testosterone a day (in healthy young men). This drop is approximately 1-2% annually after age 30\. But despite testosterone decline as we age, it is neither inevitable nor consistent across everyone.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC2544367/?ref=alphabetguides.com) In fact, some men increase their testosterone levels as they age. The production of testosterone depends on signals from your brain, adequate nutrients and testicular health.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/25295520/?ref=alphabetguides.com) ### 2\. “Availability” (how much is usable) Only 2-3% of your testosterone circulates “freely” in blood, meaning it’s not "bound" to anything. This is called “free testosterone”, and it's the biologically active form that enters your cells and does its work. Another 40-50% of your testosterone is loosely bound to a protein called “albumin” and becomes available when it's needed. The remaining 50-60% of the testosterone in your blood is tightly bound to a protein called sex hormone-binding globulin (SHBG) and is effectively locked away — it doesn’t work, your cells can't use it, it’s not “bioactive”. A critical point: You can have “normal” total testosterone levels but low free testosterone (or "bioactive" testosterone) levels if too much of it is bound to SHBG. Conversely, someone with low-ish total testosterone levels but normal free testosterone levels will have a normally functioning testosterone system, even though their blood (total) testosterone levels are low. Obesity, some other diseases, inflammation and ageing all reduce your testosterone (and free testosterone) levels.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/10442580/?ref=alphabetguides.com) ### 3\. “Receptor activity” (how well your cells respond) Even with adequate testosterone production and availability, testosterone must then go on to bind to androgen receptors (AR) inside your cells to exert its effects. The “density” and sensitivity of these receptors vary between different parts of your body and different people. The number of androgen receptors you have *can* also change in response to exercise, nutrition, body composition and your environment. ### Why the whole testosterone system matters Two men can have identical total testosterone levels in their blood (e.g., 500 ng/dL) but very different functioning testosterone systems. For example: - **Man \[A\]:** Has low or normal SHBG, high free testosterone, and a normal amount of functional androgen receptors, so he feels energetic, builds [muscle](https://www.alphabetguides.com/tag/muscle/) pretty easily, has a normal to high libido, and a stable mood. - **Man \[B\]:** Has high SHBG, low free testosterone, and poorly functioning androgen receptors, so will feel fatigued, carry too much fat, have low drive and motivation, and reduced ability to recover from exercise. The blood test shows the same number, but their testosterone systems function completely differently. Over the next nine lessons, we'll look at how to optimise each of these three parts of your testosterone system: production, availability and androgen receptor signalling. ### Tasks 1. Measure your [body weight and waist circumference](https://www.alphabetguides.com/beyond-the-scale/). 2. Rate the following on a scale of 1-10 for the next 3 days and take an average. We'll use this as a baseline. 1. Energy/drive first thing in the morning 2. How well you train or perform if/when you exercise 3. Your libido/sex drive 4. Mood 5. How stressed you are or feel 6. Your mental clarity and cognitive performance 7. How you slept (both how long and how well). --- ## **L**esson 2: The HPG axis ![A person holding two tomatoes in their hand.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1696355743338-546736da2411.jpeg) Testosterone production doesn't start in your balls ("testes" or "gonads"). It starts in your brain. Specifically, in a pea-sized region of your hypothalamus, which is the testosterone command centre of your brain. Most of the testosterone-killing mistakes happen here, in your “hypothalamic-pituitary-gonadal” (HPG) axis — not in your gonads. ### How the HPG axis works Your hypothalamus monitors your body's energy reserves, your stress levels, inflammation, and your current testosterone levels. When these are good, and your testosterone starts to drop, it sends a "signal" to your pituitary gland (gonadotropin-releasing hormone), which in turn sends a signal to tell your gonads (luteinizing hormone and follicle-stimulating hormone) to start producing more testosterone. When testosterone starts rising in your blood, your hypothalamus detects this and then tells your gonads to stop producing it. This prevents overproduction of testosterone. Your HPG axis is *highly* sensitive. When it detects “danger” (whether real or not), it suppresses your testosterone production to save energy. ### What is a “danger” to your HPG axis[\[4\]](https://pubmed.ncbi.nlm.nih.gov/33076711/?ref=alphabetguides.com) 1. **Calorie Deficits:** Significant calorie deficits decrease your testosterone levels and increase SHBG, further reducing your free testosterone levels. 2. **Sleep deprivation:** Decreases your testosterone levels, as most of your testosterone is produced while you’re sleeping. 3. **Long-term stress:** Activates areas in your brain to produce [cortisol](https://www.alphabetguides.com/what-is-cortisol/), which suppresses HPG axis testosterone signalling in your *brain* (not your gonads). 4. **Long-term inflammation:** Certain inflammatory substances that are elevated if you’re obese, have a poor diet, have some diseases or are ill, which go on to suppress your HPG axis and testosterone production. 5. **Excessive exercise:** Some exercise can boost your testosterone levels. But *too much* exercise (sometimes referred to as “[overtraining syndrome](https://www.alphabetguides.com/overtraining-how-to-diagnose-prevent-it/)”) can disrupt your HPG axis, decreasing your testosterone levels. ### Task: Avoid suppressing your HPG system 1. **Are you eating enough?** Compare what you're actually eating to what you *should* be eating. You can use an online calorie counter ([like this one](https://www.nal.usda.gov/human-nutrition-and-food-safety/dri-calculator?ref=alphabetguides.com)) to estimate how much you should be eating. 2. **Are you sleeping enough?** How many nights did you get at least 7 hours of sleep last week? Less than 3 nights or 2 nights in a row will probably affect your HPG axis function. 3. **Are you training too much?** Over 12 hours of aerobic or endurance-type exercise a week may be suppressing your testosterone levels. Try to keep training to under 8 hours a week. 4. **Are you stressed?** Are your stress levels consistently above a 7 out of 10? If so, this may be suppressing your HPG axis function. #### Clinical Note Testosterone replacement therapy for men with low-testosterone, who have suppressed HPG axis function, **may* make things **worse*: it decreases your natural testosterone production. One solution (amongst many) is to take care of the things suppressing your HPG axis (e.g., adequate sleep, calories, low stress) first, rather than just trying to synthetically replace low-testosterone levels with drugs. --- ## Lesson 3: Testosterone is made while you sleep ![A person sleeping on river.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1529435022610-ccc7cab8499e.jpeg) One week of 5-hour sleep reduced testosterone levels by 10-15% in healthy young men. Chronic sleep restriction (less than 6 hours a night for months or years) can suppress testosterone by 20-30%; this is equivalent to ageing 10–15 years.[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4445839/?ref=alphabetguides.com) _This post is for subscribers only._ ### The 3 Best Diets For Your Brain URL: https://www.alphabetguides.com/brain-health-diets/ Last updated: 2026-10-05T08:08:13.000Z summary - The MIND, Mediterranean, and DASH diets have strong evidence for protecting cognitive function as you age. - All three are rich in leafy greens, berries, oily fish, olive oil, and nuts — nutrients that are shown to protect your brain. - The MIND diet was specifically designed to support brain health; it is a more targeted version of the other two diets. Losing your cognitive abilities as you age isn’t always inevitable. Sure, genetics play a role, but so does your lifestyle. How physically active you are, how well you [sleep](https://www.alphabetguides.com/eat-for-better-sleep/), socialise, and maybe most importantly, what you eat all affect how well your brain works. What you choose to eat has been shown to affect brain inflammation (called “neuroinflammation”), the health of the blood vessels that deliver oxygen and nutrients to your brain, how well your brain cells work, and your long-term risk of developing brain diseases like dementia and Alzheimer’s. The good news is that there are diets and dietary patterns that support brain health. In this article, we’ll go through how your diet affects your brain, what nutrients and food groups you should target (and avoid), and then give you three tried and tested brain health diets. ## Why Diet Matters for the Brain Your brain is “metabolically active”. It burns through a fifth of your body’s total energy despite only accounting for two percent of its weight. Your brain is well vascularised (meaning that it receives a lot of blood) and is sensitive to what’s in your blood, and thus, what you eat. It’s not just the energy, oxygen and building materials that your brain needs from your diet; it also responds to micronutrients and other small molecules or peptides that are part of your diet. Inflammation (even at low levels) can damage brain cells and is associated with cognitive decline. Damage to your brain cells that is caused by free radicals can also be minimised by eating enough “antioxidants”. Although they are often overlooked, the blood vessels that control [blood flow](https://www.alphabetguides.com/blood-flow-restriction-training/) to and from your brain are critically important. If they are damaged or not working correctly, it can starve your brain cells of the things it needs to keep them alive and prevent the build-up of brain-damaging waste products. Even the health of your gut microbiome and “gut-brain axis” has been linked to mood, inflammation and how well your brain functions.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/28220542/?ref=alphabetguides.com) The best brain health diets will address all of these issues at the same time: they should be anti-inflammatory, antioxidant-rich, and keep your blood vessels and gut microbiome healthy. --- ## The Dietary Elements Linked to Brain Health Diets that are good for your brain contain specific foods and nutrients that have independently been shown to protect and improve cognitive function.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/28220542/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/26086182/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/28697569/?ref=alphabetguides.com) ### Leafy green vegetables Spinach, kale, rocket, and other [leafy greens](https://www.alphabetguides.com/superfood-leafy-greens/) are among the most proven brain-protective foods. They are rich in vitamin K, folate, lutein and beta-carotene antioxidants. Eating one to two servings per day has been associated with notably slower cognitive decline in older adults. ### Berries Blueberries, strawberries, and other dark-coloured berries are rich in flavonoids, which have antioxidant and anti-inflammatory properties. Regular berry consumption has been shown to delay cognitive decline as you age by up to 2.5 years. A *minimum* of 2 servings (or handfuls) of berries a week is generally recommended.[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3582325/?ref=alphabetguides.com) ### Oily fish and omega-3s The long-chain omega-3 essential fatty acids (EPA and DHA) are found in [oily fish](https://www.alphabetguides.com/superfood-oily-fish/), like salmon, mackerel, sardines, and herring. They are critically important as they form part of your brain cells’ membranes, which keep them healthy. Eating oily fish and omega-3 supplements has been shown to reduce brain inflammation, support brain cell function, and is consistently linked to better cognitive function and lower dementia risk.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/36637075/?ref=alphabetguides.com) ### Olive oil Extra virgin [olive oil](https://www.alphabetguides.com/superfood-olive-oil/) is rich in vitamin E (an antioxidant) and a polyphenol called oleocanthal, which has anti-inflammatory properties; sometimes called nature's ibuprofen. Regular use is associated with reduced inflammation and better cognitive function. ### Nuts Most nuts are high in an essential fat called alpha-linolenic acid (a plant-based omega-3), vitamin E, and lots of polyphenols. Higher nut intake is linked to better cognitive function in older adults. And walnuts in particular seem to be associated with better cognitive function in adults of all ages; they seem to contain more omega-3s and polyphenols than other nuts.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/33330927/?ref=alphabetguides.com) ### Whole grains Whole-grain, low-GI or slow-release carbohydrates are able to maintain a steady supply of energy to the brain to meet its needs. Whereas [sugary, refined carbohydrates](https://www.alphabetguides.com/reduce-sugar-intake/) spike your blood sugar levels, which can (eventually) increase inflammation, cell damage, and impair brain function. Fibre-rich, whole-grain carbohydrates are linked with a reduced risk of getting brain diseases and maintaining good cognitive function.[\[7\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC12209867/?ref=alphabetguides.com) ### Limiting saturated fat, sugar, and ultra-processed foods Ultra-processed foods, too much sugar and saturated fat increase inflammation, disrupt your gut microbiome, and damage the blood vessel system that supplies your brain. Keeping ultra-processed foods to a minimum or completely [avoiding them](https://www.alphabetguides.com/how-to-avoid-upfs/) is generally recommended if you want to optimise your brain health. --- ## The Top 3 Diets for Brain Health ### #3\. DASH diet The DASH diet was originally developed to lower blood pressure, but its brain-health benefits have also been researched. The DASH diet emphasises fruits, vegetables, whole grains, low-fat dairy, nuts, and lean proteins, while restricting sodium, saturated fat, red meat, and added sugars. The case for the DASH diet rests on its positive effects on your blood vessels. It may be surprising, but high blood pressure is one of the most important risk factors behind cognitive decline and dementia. So, by lowering blood pressure through your diet, you can protect the small blood vessels that supply your brain, which in turn can reduce the risk of blood vessel damage that harms your brain health. [DASH Diet: A ReviewA clinically developed eating plan with some of the strongest evidence for blood pressure and heart health.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-f68c5153-5505-4641-bf0e-02757e8a2dfc.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1553909489-cd47e0907980-0278c599-aede-47af-a88d-ed65c6346569.jpeg)](https://www.alphabetguides.com/dash-diet/) ### #2\. Mediterranean diet The Mediterranean diet is the most widely researched diet for general health, and its evidence for brain health is just as good. It’s based on vegetables, fruits, legumes, whole grains, olive oil, and oily fish, with moderate poultry and dairy, and limited red meat and sweets, and no ultra-processed foods. Several high-quality studies have linked the Mediterranean diet to better cognitive function, slower cognitive decline with ageing, and lower chances of getting brain diseases like dementia and Alzheimer’s disease. The closer the Mediterranean diet is followed, the better your brain health prospects are as you age.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/30826160/?ref=alphabetguides.com) The high intake of olive oil, oily fish and [colourful](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/) antioxidant-rich plants specifically keeps inflammation under control and your blood vessels healthy. In addition to the brain health benefits, the Mediterranean diet also has the broadest range of [health benefits](https://www.alphabetguides.com/mediterranean-diet-fat-loss-health/) — the diet also supports heart health, mental health, healthy body weight, metabolic health, longer life expectancy, and better quality of life. [Mediterranean DietThe Mediterranean diet is based around eating vegetables, fruits, whole grains, legumes, nuts, olive oil as the main fat, eating fish with some meat.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-726be377-da1b-4507-82f9-475f88359bfe.png)Alphabet Guides![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1550989460-0adf9ea622e2-dcd8cee5-2881-4368-941c-a440294f4bca.jpeg)](https://www.alphabetguides.com/tag/mediterraneandiet/) _This post is for subscribers only._ ### The 3 Best Heart Health Diets URL: https://www.alphabetguides.com/heart-health-diets/ Last updated: 2026-09-22T09:22:00.000Z summary - Your diet influences all the major modifiable cardiovascular risk factors — blood pressure, LDL cholesterol, blood glucose, and inflammation. - Plant diets, the DASH diet and the Mediterranean diet have the strongest and most consistent evidence for reducing cardiovascular disease risk. - All three diets share the same core principles: more plants, whole grains, and healthy fats; less saturated fat, sodium, added sugar, and red meat. Cardiovascular disease is the leading cause of death worldwide, and has been for some time. It accounts for more deaths than cancer, diabetes and lung diseases combined. However, the good news is that it is “modifiable”, meaning it can be delayed, prevented, or its effects minimised. Smoking, being inactive, having too much [body fat](https://www.alphabetguides.com/tag/fat-loss/), and a poor diet are the main drivers that you can modify. In this article, we will examine the role that your diet plays. ## Why diet matters for heart health Whatever you eat, its constituent parts will eventually find their way inside your cardiovascular system (in your bloodstream), where your heart and blood vessels are exposed to them — there is no getting around this. So, the foods you eat every day affect your blood, the elasticity of your arteries, your immune system and your metabolism. When the doctors look at how “healthy” your cardiovascular system is, they’ll look at a few risk factors: high LDL or ApoB, high blood pressure, glucose and insulin, triglycerides, inflammation, and body fat. No medication can act on all of the risk factors at the same time. But the right diet can. For people who are at risk of cardiovascular disease, changing to a heart-healthy diet can meaningfully reduce all these risk factors with minimal side effects.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/21854893/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/30764511/?ref=alphabetguides.com) --- ## The basic dietary practices that protect your heart We’ll go through specific diets in a minute, but if you don’t want to overhaul your diet entirely and prefer to adapt your current diet, there are a few basic principles that appear consistently that you should consider.[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC10128075/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/38068756/?ref=alphabetguides.com) ### Eat more plants This means eating more [vegetables](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/) (most important), legumes (also important), whole grains and fruit. They are rich in fibre, potassium, antioxidants and anti-inflammatory “phytonutrients”. Fibre reduces LDL and helps stabilise your blood sugar levels. Potassium helps control your blood pressure. The antioxidant and anti-inflammatory molecules in plants protect your blood vessels.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/36796439/?ref=alphabetguides.com) ### Choose healthy fats Unsaturated fats — found in [olive oil](https://www.alphabetguides.com/superfood-olive-oil/), nuts, seeds, avocados, and oily fish — lower cholesterol and reduce inflammation. Saturated fats from processed meats, butter, and full-fat dairy do the opposite. Replacing saturated fats with unsaturated fats is one of the easiest and most effective ways to improve heart health.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/34423871/?ref=alphabetguides.com) ### Eat whole grains, not refined ones Whole grains provide soluble fibre, which directly lowers your cholesterol. “Refined” carbohydrates spike your blood glucose and triglycerides. The swap from the white processed carbohydrates to whole-grain, whole-food carbohydrates is a quick, easy and effective substitution. ### Reduce sodium intake Eating too much sodium (mainly from salt) is the main thing in your diet that increases your blood pressure. That said, in most [modern diets](https://www.alphabetguides.com/western-diet/), the added salt comes from processed and packaged foods, not the salt shaker. Reducing your salt intake is probably not enough if you’re eating a lot of [processed foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/). ### Limit red and processed meat It’s controversial, but high consumption of red meat is associated with increased cardiovascular disease risk. This includes unprocessed red meat, but processed meat like sausages, bacon, and deli meats is generally worse. Replacing red meat and all processed meats with fish, [legumes](https://www.alphabetguides.com/plant-based-protein/), or poultry is consistently beneficial. If you’re going to eat red meat, keep servings to under 3.5 oz and two servings a week max. ### Cut out ultra-processed foods They’re high in salt, sugar, refined carbohydrates, and unhealthy fats, everything you *don’t* want for maintaining good heart health. Ultra-processed foods hit nearly every cardiovascular disease risk factor, but in the wrong direction. [Avoid](https://www.alphabetguides.com/how-to-avoid-upfs/) at all costs. --- ## The Top 3 Diets for Heart Health ### #3\. Plant-Based & Flexitarian Diets Plant-based diets cover a spectrum of diets, from fully [vegan](https://www.alphabetguides.com/vegan-diet/) to “flexitarian” diets (ones that are predominantly but not exclusively plant-based). They are sometimes referred to as “plant-slant” or “plant-forward” diets. But what unites all plant diets is that they replace animal food (especially meats) with vegetables, legumes, whole grains, nuts and seeds. You don’t have to go fully [vegan](https://www.alphabetguides.com/vegan-mediterranean/) to benefit. In people who are at risk of cardiovascular disease, a plant-based diet reduces cholesterol, blood sugar, and body weight. People who eat more plants also tend to have lower chances of getting heart disease and dying from it.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/37490288/?ref=alphabetguides.com) However, the prefix “healthy” needs to be put before plant-based diets to work. There are “unhealthy” plant-based diets that rely on refined carbohydrates (sugar and refined grains) and processed and packaged products, which do not have the same health benefits. If you don’t want to go fully plant-based, adopt a flexitarian approach by substituting animal fats with “non-tropical” plant oils (e.g., olive, [canola](https://www.alphabetguides.com/canola-vs-olive-oil/), sunflower or soybean oil, but not coconut or palm oil), red meat for [legumes](https://www.alphabetguides.com/plant-based-diet-meal-plan/) and refined carbohydrates for vegetables is a great start to capture the health benefits.

DASH Diet The “DASH” diet (short for Dietary Approaches to Stop Hypertension) was specifically designed (and proven) to target high blood pressure. The DASH diet is similar to the Mediterranean diet, emphasising plants, whole grains, low-fat dairy, nuts, and lean proteins, while restricting sodium, saturated fat, red meat and added sugars. The blood pressure-lowering effects of the DASH diet are among the largest seen for any diet (or other non-drug treatments) — it's actually comparable to some antihypertensive medications.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/30764511/?ref=alphabetguides.com) In addition to lowering blood pressure, the DASH diet also lowers cholesterol, insulin and your chances of getting diagnosed with cardiovascular disease, stroke, coronary heart disease and type 2 diabetes.[\[8\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3712342/?ref=alphabetguides.com) Its main distinction from the Mediterranean diet is the strict sodium limits (under 2.3 g or approximately 1 teaspoon of salt) and the inclusion of low-fat dairy, which provides calcium, magnesium, and potassium. It’s the rebalancing of these minerals that helps keep your blood pressure low and under control. There is probably no other diet that has been as rigorously tested for treating high blood pressure as the DASH diet.

Basing your food intake on it is riddled with error, making weight loss harder than the "maths" suggests. - Protein is probably the most underrated fat-burning nutrient. It helps with fat loss and maintaining a healthy body weight in 4 different ways. - Food quality and nutrient density are also underrated. Protein and fibre-rich low-energy-density foods are what you should fill your diet with. "Calories in, calories out." It's the fundamental equation determining "energy balance," which governs your [body weight](https://www.alphabetguides.com/tag/fat-loss/). Or is it? The physics behind the energy balance equation is solid, but the application of it is not as straightforward — and even if you get the maths right, *what* those calories are made of changes how easy or hard the whole weight loss process feels. ### Energy balance: The maths At its core, body weight change follows the first law of thermodynamics: "energy cannot be created or destroyed, only transferred or transformed". When energy intake exceeds energy expenditure, the excess is stored, primarily as fat tissue. But when expenditure exceeds intake, stored energy is mobilised to meet the deficit — mainly from fat, but also from carbohydrate and protein stores in the liver and [muscles](https://www.alphabetguides.com/tag/muscle/).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/22434603/?ref=alphabetguides.com) Energy intake and expenditure are usually measured in "calories," which are actually kilocalories (1,000 calories = 1 kilocalorie). Your body (like everything else) follows the laws of physics, making energy balance the ultimate determinant of [successful fat loss](https://www.alphabetguides.com/fat-loss-beyond-diet-exercise/). However, the apparent simplicity of this equation masks a lot of complexity in both measuring it and adjusting its individual parts to "create" a calorie deficit. In our opinion, you're better off focusing on doing things that *lead to* a negative energy balance, rather than obsessing over energy balance itself. ### Calories in: Why tracking is harder than it looks Energy intake is easy to measure, but difficult to measure correctly. You can have the most detailed, sophisticated tracking system in the world, and it still won't measure what your body is actually absorbing. Food-logging studies generally show underreporting of energy intake by 10–20%, though some people underreport by 40% or more. This comes down to:[\[2\]](https://pubmed.ncbi.nlm.nih.gov/25394308/?ref=alphabetguides.com) - Misjudging portion sizes. - Failing to account for calorie-dense additions (cooking oils, spreads, condiments). - Different cooking or processing methods. - Selective counting (ignoring weekends or eating out) and relying on flawed food databases. - Restaurant and pre-packaged food labels are notoriously inaccurate, and liquid calories (e.g., milk, alcohol, sodas, and sauces) are frequently overlooked entirely. Add up all these errors, and you're really left asking: how good is your educated guess? Trying to get it to the nearest 100 calories — no chance. ### Calories out: Your total daily energy expenditure The other side of the equation is your total daily energy expenditure, and it has four components: 1. [**Basal Metabolic Rate**](https://www.alphabetguides.com/basal-metabolic-rate/): The energy required for your basic biological needs. Accounts for roughly 60–75% of your energy expenditure for most people. 2. **Thermic Effect of Food**: The energy required to digest, absorb, and use the energy you've eaten — usually 8–12% of energy expenditure. 3. **Exercise Activity Thermogenesis**: all planned [exercise](https://www.alphabetguides.com/tag/exercise/). Typically, 5–15% of energy expenditure, but can exceed 50% for very active people and drop under 5% for inactive ones. 4. **Non-Exercise Activity Thermogenesis**: all other movement that isn't sleeping, eating, or exercising — fidgeting, posture, incidental activity. It varies enormously between people (think farmworker versus desk worker) and is a crucial, often-overlooked component of energy balance.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/12468415/?ref=alphabetguides.com) All four components fluctuate day to day and hour to hour, which makes assumptions about how much energy they use genuinely difficult. Exercise is relatively easy to track — minutes, sessions, distance. But when you reduce how much you're eating, your body also reduces how much it expends. This is called "metabolic adaptation" or "adaptive thermogenesis." Your basal metabolic rate drops as your organs become more energy-efficient, and you subconsciously reduce your non-exercise energy expenditure too, resting more and moving less. These compensatory behaviours can add up to hundreds of calories a day. Your body isn't trying to sabotage your diet; these are evolutionary survival mechanisms that kept us alive through famines.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/20935667/?ref=alphabetguides.com) ## Why Most Diets Fail _This post is for subscribers only._ ### The 3 Best Fat Loss Diets URL: https://www.alphabetguides.com/fat-loss-diets/ Last updated: 2026-09-22T09:17:55.000Z summary - No single diet, by itself, is superior for the sole purpose of fat loss — what matters more than anything is creating a sustainable calorie deficit. - That said, Mediterranean-style diets, high-protein diets and intermittent fasting diets do it better than most other diets. - Each of these diets has unique advantages for fat loss, which don’t conflict with each other, so they can be used together. The weight loss diet industry is worth billions of dollars, so there’s a new “revolutionary” diet every few months. It arrives, it’s promoted, it’s adopted, it fails, it’s forgotten, then repeat. Does anyone remember the grapefruit, cabbage soup or tapeworm diet? Most of them are forgotten within a year, even the ones that partially work or may have a bit of scientific evidence behind them. Paleo diets, keto diets and the carnivore diets all fall under this category. The diets that actually work (and keep working) tend to stand the test of time. They’re tried and tested, and they tend to share the same few quiet, unglamorous features. In this article, we’ll name three of the best ones. We’ll discuss what drives fat loss from a dietary standpoint, identify what works and then (in our opinion) give you the three best dietary approaches that are proven and sustainable. ## What actually drives fat loss? Before comparing diets, it is worth being clear on the basics. Fat loss happens when your body uses more energy than you consume — a calorie deficit. This is not controversial; it’s physics and facts. You can’t really lose a significant amount of fat without a calorie deficit. Where diets differ is *how* they help you reach, and then maintain, the calorie deficit. Some diets work by increasing how full you feel. Some diets rely on temporary motivation, mind games, willpower or strict rules. Some make overeating more difficult. Some are even able to [shift your hormone balance](https://www.alphabetguides.com/keto-diet/). However, the “best” (or most effective) fat loss diets are the ones that make it easy to eat slightly less food, so they can be sustained long-term. Here are a few common features of them. ## Dietary protein Most of the debate around fat loss over the last few decades has been low-carb versus low-fat. But, until recently, the third macronutrient, protein, had tended to be overlooked. Eating dietary protein preserves muscle while you’re losing fat; it makes you feel fuller for longer, and it contains fewer calories, gram-for-gram, than fat *and* carbohydrate (when you account for its [thermic effect](https://www.alphabetguides.com/3-underrated-ways-to-lose-fat/)). Several studies have shown that high-protein diets produce better fat loss outcomes compared to lower-protein equivalents.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/25926512/?ref=alphabetguides.com) ## Dietary fibre High-fibre foods slow digestion, stabilise your blood sugar levels, and reduce your appetite. They also tend to have lower [energy density](https://www.alphabetguides.com/volumetrics-diet/), which means you can eat a larger volume of food for fewer calories. Diets rich in vegetables, legumes, and whole grains are consistently associated with better weight outcomes.[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6163457/?ref=alphabetguides.com) ## Adherence Adherence is probably the most underrated factor of all. And the research is unusually consistent here: across well-designed head-to-head diet trials, the differences in weight loss between dietary approaches largely disappear when adherence is the same. We see this all the time, where a new diet may outperform another (more established) one over 3 or 6 months. But by 12 or 24 months, fat loss is roughly the same. In other words, the best diet is one you can stick to forever, or at least long enough to reach a healthy body weight (after which it can be adjusted). A year is usually the minimum. So, before you commit to any diet, think about whether you can see yourself following it in a year. --- ## The Top 3 Diets for Fat Loss ### #3\. Intermittent Fasting Intermittent fasting is not a “diet” in the traditional sense — it is about *when* you eat rather than *what* you eat. The [most common formats](https://www.alphabetguides.com/types-of-intermittent-fasts/) are time-restricted eating (typically a 16-hour fast with an 8-hour eating window, known as 16:8), alternate-day fasting, and the 5:2 approach (normal eating five days a week, very low calories on two non-consecutive days). Intermittent fasting produces comparable results to standard “continuous” calorie-restriction diets when total calorie intake is the same. These short intermittent fasts do not offer any special metabolic advantages, but they do offer a structure that many people like and can follow.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31443231/?ref=alphabetguides.com) Compressing your eating into a shorter window naturally reduces the opportunity to eat, without having to count and keep track of your calories and/or macros all day long. Most intermittent fasting protocols report meaningful fat loss (and health benefits). However, in our opinion, the 16:8 has the best returns. It has the highest ranking results and adherence, and it fits around normal sleep and daytime eating patterns.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/33293678/?ref=alphabetguides.com) In practice, what it means is eating your breakfast later, your dinner earlier, or rolling either of them into your lunch or a daytime snack. Out of the two of them, the early window seems to be marginally better, where you stop eating earlier in the day (commonly referred to as “early time-restricted eating”). Intermittent fasting is flexible and not a complete dietary approach, so it can be combined with other eating patterns (e.g., Mediterranean or high-protein diet). But like other diets, the key to successfully implementing it is finding a fasting protocol that you can maintain, that fits your schedule and lifestyle. [FastingEvidence-based articles on fasting, including intermittent fasting, time-restricted eating, and the science of how fasting affects your body and health.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-ac55304f-5247-436d-8112-c42877baff16.png)Alphabet Guides![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1763891538128-cdad95beb521-0e406ac6-99cf-43b2-a322-e2dfc4d6638f.jpeg)](https://www.alphabetguides.com/tag/fasting/) ### #2\. High-Protein Diet A high-protein diet is typically defined as one where protein makes up over 25% or more of total calorie intake (or over 1.2 grams per kg per day) — meaningfully above the average of 15–17% in most [Western diets](https://www.alphabetguides.com/western-diet/). Technically, high-protein diets don’t focus on any particular food group, though they, *de facto,* tend to lean towards eating more lean meats, fish, eggs, dairy, and legumes than normal. The case for higher protein for fat loss is the strongest of any of the macronutrient changes. Protein is the most filling macronutrient — it reduces the release of your “hunger hormones” and increases “satiety signals” more than carbohydrates or fats do. It also has the highest “thermic effect”, meaning around 20–30% of the [calories in protein](https://www.alphabetguides.com/eat-to-lose-fat/) are used to digest it. And lastly (and most importantly), it preserves muscle mass while in a calorie deficit, which makes [fat loss](https://www.alphabetguides.com/body-recomposition-lose-fat-gain-muscle/) a lot easier. High-protein diets produce better fat loss outcomes than lower-protein diets, even when total calories are the same. However, there are some practical challenges. Some very high protein intakes can become repetitive and expensive. So, we recommend moderate increases (e.g., *at least* 20% of calories or 1 gram per kg a day), which should be layered onto another healthy dietary pattern (e.g., the [Mediterranean diet](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/)). Just reaching a high daily protein target isn’t enough by itself, especially if you also want to maintain (or improve) your health while losing fat.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/18635428/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/24472635/?ref=alphabetguides.com) [High Protein Diets: A ReviewA well-supported dietary strategy for fat loss, muscle maintenance, and long-term appetite control.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-cdca064f-39c7-4700-8b13-425ee367a206.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1670398564097-0762e1b30b3a-498a989a-85ea-4fa7-98bc-e401f2a10f42.jpeg)](https://www.alphabetguides.com/high-protein-diet/) _This post is for subscribers only._ ### 8 Things the Healthiest Diets Have in Common URL: https://www.alphabetguides.com/healthiest-diets/ Last updated: 2026-09-18T11:34:08.000Z summary - We reviewed eight of the world's healthiest diets to identify eight of the healthiest features that they all have in common. - All the diets are plant-based, have a pretty much balanced macronutrient profile, favour whole grains over refined ones, and regularly eat legumes and oily fish. - They cut out ultra-processed foods, limit red meat and keep the rules and recommendations flexible. We have reviewed over 30 diets, which include some of the world’s healthiest diets and eating patterns. These include the Mediterranean, [DASH](https://www.alphabetguides.com/dash-diet/), [TLC](https://www.alphabetguides.com/tlc-diet/), [Anti-inflammatory](https://www.alphabetguides.com/anti-inflammatory-diet/), [Volumetrics](https://www.alphabetguides.com/volumetrics-diet/), [Blue Zone](https://www.alphabetguides.com/blue-zone/), [Nordic](https://www.alphabetguides.com/nordic-diet/) and the [MIND](https://www.alphabetguides.com/mind-diet/) diets. Looking at these diets next to each other, one thing becomes clear — they share more similarities than differences. In fact, they are all pretty much related to each other in one way or another; they’re really a family of diets, which all descend from the [Mediterranean diet](https://www.alphabetguides.com/mediterranean-diet-review/). So it comes as no surprise that the same foods, patterns and eating habits turn up again and again. There are no brand names. No special products or gadgets required. There is no specific ratio of carbs or fat. Taken collectively, there are dozens of studies showing that all these diets are safe, healthy, nutritious and can be followed easily by vast swaths of people. Here’s what they all have in common. The foods that appear repeatedly, the habits that recur across every culture and continent, are the real story. Not the brand name. Not the specific ratio of carbs to fat. The patterns underneath. --- ## 1\. Plants front and centre All eight diets are built around plants, all of which fall under the plant-based diet umbrella. Vegetables, fruits, legumes, nuts, seeds, and whole grains make up the majority of calories in each of these diets. This is no coincidence. Several independent studies have shown that the more plants you eat, the lower your chances of getting heart disease, type 2 diabetes, certain cancers and shorter life expectancy. The Blue Zone diet gets over 80% of its calories from plants. The Mediterranean and Anti-inflammatory diets are high in vegetables and olive oil. The MIND diet calls for at least six servings of leafy greens a week. The Nordic diet promotes eating berries, root vegetables, and whole grains. Although all the diets are “plant-forward”, none of them recommend going fully [vegan](https://www.alphabetguides.com/vegan-diet/). However, let’s be clear: plants are the main event with everything else playing a supporting role. [Plant-BasedEvidence-based resources on plant-based diet meal planning, recipes, and health benefits: clear, practical guidance for healthier eating.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-77f46843-1d99-4bb4-83bc-d8ce98ff967c.png)Alphabet Guides![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1566385101042-1a0aa0c1268c-f7b3f50c-6bdb-4e6b-a4a3-dd49bfcadbb4.jpg)](https://www.alphabetguides.com/tag/plant-based/) --- ## 2\. Whole grains are preferred over refined ones None of the healthiest diets is “low-carb” or fear carbohydrates. In fact, in all of the diets, carbohydrates are the main macronutrient, making up anywhere from 40 to 60% of total calories. [Oats](https://www.alphabetguides.com/oats-health-benefits/), brown rice, rye, barley, quinoa, and whole wheat — these feature in all of the diets. But what's absent is just as telling: white bread, refined cereals, and processed grain products are consistently cut back or completely absent. Whole grains provide fibre, B vitamins, and magnesium, and release energy more slowly than their refined equivalents. This helps keep your blood sugar levels and hunger low and stable. The TLC diet recommends at least six servings of whole grains daily. The DASH diet recommends six to eight. The Nordic diet promotes eating rye and oats. The logic is the same across all of them: unprocessed grains keep your gut and [heart healthy](https://www.alphabetguides.com/heart-health-diets/). --- ## 3\. Legumes are a staple, not an afterthought Lentils, chickpeas, black beans, kidney beans, edamame — these appear consistently across all eight diets, and in some (e.g, Blue Zone and Mediterranean), they serve as the primary [source of protein](https://www.alphabetguides.com/plant-based-protein/). Legumes are high in protein and fibre and low in saturated fat. They are inexpensive and filling. They are linked to lower cholesterol, better blood sugar control, and reduced cardiovascular disease risk. The MIND diet recommends beans at least four times a week. The DASH and TLC diets both include three to five servings a week. If there is a single food that consistently appears among the world’s healthiest diets, it is probably the humble bean. [Health Benefits of Legumes: Just One Can a WeekAdding just one simple can of legumes a week to your weekly shop can transform your heart and gut health, your wallet, and the planet.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-e14c157d-1fee-4037-b4eb-6ca6dd1532f0.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1599579085809-4edbc35cee01-82fb58d8-0160-419e-893f-ab3a6406af66.jpg)](https://www.alphabetguides.com/legumes-and-health/) --- ## 4\. Healthy fats are favoured over saturated ones None of the eight diets eliminates fat. In fact, several of them are relatively high-fat (around 25-40% total calories). However, what they share is a clear preference for unsaturated fats like [olive oil](https://www.alphabetguides.com/superfood-olive-oil/), rapeseed oil, nuts, seeds, and oily fish, over saturated fats from butter, full-fat dairy, processed foods and fatty meats. The Mediterranean diet is built around extra virgin olive oil. The Nordic diet uses rapeseed oil as its primary fat. The TLC diet emphasises replacing saturated fat with unsaturated fats. The DASH and MIND diets both include nuts and oily fish. The consistent swap from saturated to unsaturated fat is shown to lower LDL cholesterol, inflammation and support cardiovascular health. --- ## 5\. Eat oily fish regularly Salmon, mackerel, herring, sardines, trout — [oily fish](https://www.alphabetguides.com/superfood-oily-fish/) appear regularly across six of the eight diets, and are at least an encouraged choice in all of them. Oily fish are rich in omega-3 fatty acids (EPA and DHA), which are shown to lower blood triglycerides, blood pressure, inflammation and support brain health. The Mediterranean diet recommends fish at least twice a week. The Nordic diet positions herring and salmon as the centrepieces of meals. The MIND diet includes at least one serving a week specifically for [brain health](https://www.alphabetguides.com/tag/brain-health/). The DASH and TLC diets both recommend fish as a better protein option over red meat. As far as protein recommendations go, none of the diets gives a numbered target, but all advise eating oily fish at least twice a week. --- ## 6\. Cut out ultra-processed foods This is the point on which all eight diets are in agreement: [ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/) have no place in a healthy diet. Crisps, ready meals, fast food, packaged biscuits, sugary cereals, processed meats, and fizzy drinks are either eliminated or significantly restricted across all of the diets. The reasons are [well known](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/). Ultra-processed foods are usually high in added sugar, refined carbohydrates, unhealthy fats, and sodium, while being low in fibre, vitamins, and minerals. They are engineered to override your natural hunger cues, making it easy to overeat them without noticing. They are designed for over-consumption. People in the Blue Zone regions consume almost no ultra-processed foods. The Volumetrics diet works by replacing calorie-dense processed foods with water-rich whole foods. The MIND, Anti-inflammatory, TLC, DASH, and Nordic diets all explicitly recommend cutting out processed food as a central goal.

URL: https://www.alphabetguides.com/deload/ Last updated: 2026-09-22T09:42:06.000Z summary - Complete rest deloads can impede (or slow) progress, so reducing training volume and intensity while maintaining frequency is better. - Beginners and recreational lifters training 2–3 times per week at moderate intensity probably don't need planned deloads. - The most reliable signal for a deload is persistent fatigue that doesn't clear with normal rest. Gym lore and most training programmes treat deloads as non-negotiable — something every serious lifter must do every month or two. But the reality is more complex than that. A deload can indeed be a powerful tool for managing fatigue and protecting your progress. But it can also be unnecessary. It depends on how you train and how your body is responding to training. ## What is a deload week? A deload is a short, planned period (typically one week) — where you reduce the overall amount of training ‘stress’. You can still train. You can still perform your usual exercises. But you may reduce how much training you’re doing (‘volume’) and how hard you’re training (‘intensity’). The goal isn’t necessarily to completely rest — a deload isn’t a rest or recovery day. It has a different function. The purpose of a deload is to clear any accumulated, residual or ‘low-grade’ fatigue that has come from previous hard periods of training. The idea is to do this without losing any of the gains you’ve built. You can still go to the gym. You can still perform your usual exercises. But you pull back on how much work you do (volume) and how hard you push (intensity). The goal is not to rest completely; it is to lower the training load enough that your body can clear the accumulated fatigue from previous hard weeks of training, without losing the fitness or strength you have built. Think of it as backing off the accelerator rather than hitting the brakes.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/38499934/?ref=alphabetguides.com) ## The science behind deloading: why fatigue accumulates Progressive training (particularly resistance-based training) works by applying stress to your muscles that is just beyond what they can comfortably handle (commonly referred to as ‘overload’). After your body is exposed to these training loads, it adapts, gets stronger, and then you can apply a bit more stress the next time you train; collectively referred to as ‘progressive overload’. It is a [basic principle](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/) behind nearly all endurance, strength and bodybuilding training. But there is a problem. ‘Adaptations’ and performance improvements take a while to notice (weeks or months). Whereas fatigue starts accumulating immediately. Over several weeks of training, you may find that at some point your performance starts to plateau, or even gets worse. You start to feel tired even after resting, your body feels sore, or you’re simply not recovering your performance between sessions as quickly as you used to. This is not abnormal or unexpected; it’s a well-known and predictable response to sustained high-effort training.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/32602418/?ref=alphabetguides.com) The theory goes that a deload, used at the right time, is intended to prevent you from reaching this state — or get you out of it if you’re already there. It has also been proposed that it can reduce the monotony (or boredom) of training, injury risk, and increase your chances of sticking to it. --- ## Does deloading actually work? What the evidence shows The honest answer is that there is no straight yes or no that it ‘works’. Research does support the theory behind deloading. Training causes fatigue. If you train while you’re fatigued, you will not train as well. Different types of training lead to different amounts of fatigue. And the amount of fatigue and the time it takes to recover from it are not always predictable; it varies. This is why it is often advised that you monitor it.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/25200666/?ref=alphabetguides.com) This is why athletes and coaches use deloads and report that they find them effective. However, the evidence supporting deloads is mixed. Some studies have shown that a deload week (of complete rest) actually impedes training outcomes, or does not affect them at all.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/38274324/?ref=alphabetguides.com) This doesn’t necessarily mean that deloads are useless. It really suggests that taking a whole week off (of complete rest) may not be the right approach to deloading. Perhaps what the evidence seems to point towards is a reduction in the training load (or ‘stress’) of the individual training sessions. This means keeping the [amount of rest](https://www.alphabetguides.com/rest-and-body-composition/), the training frequency and the type of training the same, but reducing the volume and/or the intensity of each training session. ## Who needs a deload — and who doesn't? The evidence shows that not everyone needs to deload on a fixed schedule. Deloads aren’t needed for people whose training doesn’t create any measurable fatigue, or people whose fatigue is completely resolved in between training sessions, with rest.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/37730925/?ref=alphabetguides.com) If you have no measurable fatigue, you’re fully recovered, able to fully recover and able to perform exercise to the best of your ability, why do you need a deload? So who may need one? - Experienced high-end lifters and athletes who are consistently training at high volumes and intensities. - People who go through different periods, phases or types of training. Deloads tend to be taken at the start, end or midway through a period of planned training. - People who follow monotonous, boring, high-frequency or fatiguing training programmes. Beginners and people who are recreationally training probably don’t need to worry about deloads. If you’re only training 2-3 times a week at moderate intensities, you’re probably giving yourself enough time to fully recover between sessions. Likewise, if your training is well managed, you can comfortably handle the training loads, you’re [sleeping well](https://www.alphabetguides.com/tag/sleep/) and eating well, and you’ve not noticed any drop-off in your performance — you may not need a deload. The best signal is always how you are actually feeling and performing, not just what’s on the calendar. --- ## Signs you might need a deload (what to look for) Rather than sticking to a fixed schedule, many coaches and athletes follow a ‘reactive’ approach: plan your deloads strategically, but keep it flexible; use signals to confirm whether it is needed (or not). This is called an ‘autoregulated’ deload5, based on. 1. Persistent fatigue that doesn’t clear after a normal rest day. This may be waking up ‘tired’ despite getting enough sleep, feeling that your energy is ‘sapped’, taking longer to recover, or that you start getting tired a lot quicker into a training session than you normally do. 2. Stalling or declining performance is another clear sign. This happens despite reaching your training targets, recovering, sleeping and eating well. 3. Persistent aches and pains that don’t get better with rest between sessions. You will likely get some soreness after a difficult training session, but this soreness is ‘new’; it is more intense or lasts longer than you’ve had before. 4. Reduced motivation to train, increased irritability, or disrupted sleep, though these are more subjective. Ensure they are not caused by other things outside of your training (e.g., personal life, work stress, or other worries). ## How to deload: volume, intensity and duration _This post is for subscribers only._ ### Is Weight Training Good for Children & Teenagers? URL: https://www.alphabetguides.com/weighlifting-children-teens/ Last updated: 2026-09-15T14:00:21.000Z summary - Weightlifting is safer for children and teens than a lot of other sports. The dangers and growth-stunting concerns are mostly overblown. - The benefits differ by age group. All children will get stronger and learn how to move better. But only teens can grow their muscles. - Beyond the muscular benefits, weightlifting can also improve their cardiovascular health, bone health, and mental health. The image of children and teenagers lifting weights often provokes concerns amongst parents, coaches, and even paediatricians. So, myths about stunted growth, increased injury risk, and inappropriate types of training have created unnecessary barriers to youth participation in weightlifting.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/19620931/?ref=alphabetguides.com) However, the scientific evidence presents a different picture. Properly supervised strength training represents not only one of the safest ways to exercise, but also one of the most beneficial activities young people can engage in. The benefits go beyond [muscle](https://www.alphabetguides.com/tag/muscle/).[\[2\]](https://pubmed.ncbi.nlm.nih.gov/24055781/?ref=alphabetguides.com) ## Is Weightlifting Safe for Children & Teens? Perhaps the most persistent myth surrounding weightlifting is the safety and injury risk. Studies show that injury rates for supervised resistance training are *comparable* to (and sometimes lower than) those of other popular sports and activities. Most of the injuries that happen are due to improper supervision, inappropriate exercise selection, attempting to lift weights that are too heavy or inadequate preparation and warm-ups. The growth stunting concerns are largely unfounded when proper technique is used under qualified supervision.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/19620931/?ref=alphabetguides.com) ## Is Weightlifting Healthy for Children & Teens? In prepubertal children, the adaptations to weightlifting are primarily "neurological" (e.g., improved strength and movement efficiency) rather than muscle size increases. But, during and after puberty, hormonal changes, including increases in the “muscle-building” [hormones](https://www.alphabetguides.com/tag/hormones/) (e.g., testosterone, growth hormone, insulin-like growth factor-1), create a more favourable environment for muscle growth and actual muscle growth.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/28795003/?ref=alphabetguides.com) #### Other Benefits of Weight Lifting: Besides Muscle![\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC10587249/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/32457216/?ref=alphabetguides.com) - Improving cardiovascular fitness - Better body composition (i.e., less fat, more muscle) - Bone density - Metabolic and general health in overweight children and teens - Injury prevention - Mental health and well-being (e.g., self-esteem, body image, self-confidence) - Intelligence and academic performance --- ## Weightlifting for Youth: Age-Appropriate Programming Safe and effective weightlifting must be tailored to the developmental stage rather than chronological age alone. Movement skills and biological maturation vary considerably among same-aged children. This means that individual assessment and programming are essential.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/24055781/?ref=alphabetguides.com) ### Preadolescent children (ages 6-11) Emphasis should be placed on fundamental movement skills, body weight exercises, and light resistance training with perfect technique. The primary goal here is to develop movement "competency" (i.e., be able to control their own body's movements), establish good exercise habits, and create positive associations with physical activity. ### Early teens (ages 12-15) They can begin incorporating more structured weightlifting training programmes whilst maintaining emphasis on technique and *gradual* progression. This group can benefit from introducing basic barbell and dumbbell exercises whilst continuing body weight training. ### Late teens (ages 16-18) Late teens can engage in more advanced weightlifting programmes like those used with adults. This should only be started once they have developed adequate movement competency and training experience with lighter weights and their own body weight. Supervision and appropriate progression are *still* advised even for this age group. These age ranges provide general guidelines, though individual assessment of maturation status, movement competency, and training readiness remains more important than chronological age alone. In most cases, children and teens should *not* be using strength training equipment without supervision from a qualified strength training professional. This supervision ensures proper technique, appropriate exercise selection, and suitable progression whilst creating a safe and positive learning environment. --- ## How Children & Teens Can Train Safely Successful weight training programmes need careful planning that considers the child's individual development, the resources that are available, and long-term ("life-long") goals. Rather than simply scaling down adult programmes, training should follow principles specifically designed for teens and children. Progressive overload is typically based on movement and skill development rather than load and volume. Younger weightlifters should master bodyweight exercises and prove they can perform exercises with proper movement technique before progressing to add external weight. Variety and enjoyment should be integral components of training programmes to maintain engagement and prevent boredom. Games, challenges, and varying activities can make weight training enjoyable while still providing benefits. Support from instructors and parents will help maintain interest.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/19620931/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/28795003/?ref=alphabetguides.com) ### Common challenges Despite the clear benefits, there are also several challenges. Addressing most of these challenges requires education, proper planning, and realistic expectations. - The availability of qualified supervision represents perhaps the greatest challenge. Most children will lack access to exercise professionals with appropriate experience. - Equipment. This means access to appropriately sized equipment and lighter weights for initial training. Standard adult equipment may not suit smaller body frames or developing strength levels. - Time constraints in school-based programmes typically limit the quality and frequency of training sessions. Creative programming that works *with* existing physical education can help overcome time issues. - Parental concerns: whilst well-intentioned, they can create barriers to participation. Education about safety and the clear benefits can help address these concerns. --- ## Bottom Line Youth resistance training is safer than many popular sports when properly supervised, with injury rates and growth-stunting concerns scientifically unfounded with appropriate programming and qualified supervision. Successful youth programs emphasise movement competency over load progression, incorporate variety and enjoyment, provide qualified supervision, and deliver benefits beyond strength, including improved cardiovascular health, bone health, injury prevention, and psychological wellbeing. --- #### Sources 1.

The aim is to return to a healthy diet as quickly as possible. The BRAT diet is a short-term eating plan that is used to help settle the stomach after a bout of diarrhoea, vomiting, or acute gastroenteritis. The name is an acronym for its four core foods: **Bananas, Rice, Applesauce, and Toast**. These are all bland, low-fibre, easy-to-digest foods (“low residue”) that are gentle on an irritated digestive system. The diet has been a staple of home and clinical advice for decades (particularly for children) and was once the standard recommendation from doctors after any stomach illness. Today, it is viewed more as a brief transition tool than a proper treatment option.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/22706834/?ref=alphabetguides.com) Most current guidelines recommend returning to a normal, balanced diet **as quickly as possible**. That said, it still has a practical role in the first day or two of recovery, when eating anything more substantial can feel like too much.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/24739189/?ref=alphabetguides.com) The rationale behind the diet is straightforward. When the gut is inflamed, tired or overactive, simple, starchy, low-residue foods are easier to process and less likely to aggravate symptoms — it's the hands-off approach, a rest day (or two) for your digestive system. However, there are some other benefits: bananas provide potassium (often depleted through diarrhoea and vomiting) and “pectin” (a soluble fibre that can help firm up stools); rice and toast provide simple carbohydrates for energy without stimulating the gut, and applesauce offers gentle natural sugars and more pectin. Critically, the BRAT diet is always used alongside, *not* instead of, adequate fluid and electrolyte replacement. Sometimes soup or broth is recommended alongside the other foods for hydration and their salt (and sodium) content. Oral (re)hydration is the most important step in managing gastroenteritis; the BRAT diet comes second.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/14627948/?ref=alphabetguides.com) --- ## Example foods and dishes - **Breakfast:** - Plain white rice porridge (congee) with a pinch of salt - White toast (no butter) with a thin spread of applesauce - **Lunch:** - Small bowl of plain boiled white rice with a mashed banana on the side - Plain white toast with a small portion of applesauce - **Snack:** A ripe banana or a small pot of smooth applesauce - **Dinner:** - Plain boiled white rice with a light, salt-based broth - Mashed banana with a small bowl of plain rice - **Dessert:** Plain applesauce, served at room temperature - **Drinks:** Oral rehydration solution, water, clear broth, weak herbal tea --- ## Pros The BRAT diet does exactly what it is designed to do: provide easy-to-tolerate food during the worst of a stomach illness. The four foods that form the diet are bland enough to be palatable when you're nauseous and low enough in fibre and fat to avoid aggravating an already upset gut. Rice-based foods in particular have been shown to reduce stool frequency (particularly in children) with acute diarrhoea, and the pectin in bananas and applesauce may also help normalise stool consistency.[\[4\]](https://www.ncbi.nlm.nih.gov/books/NBK538500/?ref=alphabetguides.com) The diet is also very practical, which contributes to its popularity. All four foods are inexpensive, widely available, and familiar across age groups from toddlers to older adults. There is no complication, preparation, equipment or cooking skills required. Plain white rice and toast require minimal effort, which matters a lot when you are feeling unwell. Community health programmes have shown that families quickly understand and implement BRAT diets for home care for stomach upsets, suggesting it is genuinely accessible as first-line guidance — for most medical treatments, this is half the battle. The diet is pretty safe for the short period it is intended to be used (1-2 days), provided fluids and “electrolytes” (mainly sodium) are being replaced alongside it. ## Cons The BRAT diet's biggest limitation is that it is nutritionally very poor — this is done by design. It is extremely low in protein, fibre, fat, vitamins, and minerals (particularly calcium, vitamin D and B12). This is fine for one or two days while the stomach is recovering, but it becomes a problem if followed for any longer. Protein and certain micronutrients are essential for recovery, repair and immune function, all of which matter during recovery from illness. Prolonged use can actually slow recovery rather than support it. This is why a lot of experts have stopped recommending it as standard practice (certainly beyond a day or two), and instead recommend a broader, more diverse, "bland diet" that includes gentle, low-fibre, and low-fat foods, and returning to normal eating as soon as it can be tolerated. Early reintroduction of a varied diet supports recovery better than prolonged restriction.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/24739189/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/15797862/?ref=alphabetguides.com) The diet is also not suitable as anything other than a temporary measure. It has no role in weight management, long-term gut health, or any condition other than short-term acute digestive upset. Using it for longer than intended, or outside of that specific context, offers no benefit and risks creating nutritional deficiencies and other health issues. --- ## Bottom Line The BRAT diet is a sensible, practical, **short-term** tool for getting through the worst one to two days of a stomach illness. It is easy to follow, gentle on the gut, and broadly appropriate for adults and children (ensuring that you are properly hydrated). Its limitations are just as clear: it is not nutritionally adequate beyond the very short term, and it should be followed by a rapid return to normal eating. There are also more varied, healthier diets available (e.g. low-residue or bland diet) that do a similar job (if not better for some conditions). If symptoms persist beyond a couple of days or if there are signs of dehydration, medical advice should be sought rather than continuing on BRAT foods alone. --- #### Sources 1.

The anti-inflammatory diet is not a single, fixed programme with a rulebook. It is more of a way (or “pattern”) of eating. The basic idea is simple: some foods trigger or exacerbate inflammation in the body, while others help mitigate it. This diet is based on foods that focus on the latter. Persistent “low-grade” inflammation is now understood to be a driver of a lot of the most common diseases out there — heart disease, type 2 diabetes, arthritis, and even mental health issues. An anti-inflammatory diet works by reducing that background inflammation over time, through the choices you make at every meal or snack In practice, this means eating a variety of fruits and vegetables, whole grains, legumes, nuts, seeds, olive oil, and oily fish, while reducing consumption of processed foods, red and cured meats, refined carbohydrates, added sugars, and saturated fats. There is *a lot* of overlap with the Mediterranean, [DASH](https://www.alphabetguides.com/dash-diet/) and [MIND diets](https://www.alphabetguides.com/mind-diet/) (and that’s no coincidence). The Mediterranean diet is one of the most-studied anti-inflammatory diets in the world, and it forms the backbone of what most experts mean when they talk about eating to reduce inflammation.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/36039924/?ref=alphabetguides.com) --- ## Example foods and dishes - **Breakfast:** - Greek yoghurt with mixed berries, flaxseed, and a drizzle of honey - Avocado on whole-grain toast with smoked salmon and cucumber - **Lunch:** - Grilled sardines with a green salad, olive oil, lemon, and whole-grain bread - Spiced chickpea and spinach stew with brown rice - **Snack:** A small handful of walnuts with a few squares of dark chocolate (70%+) - **Dinner:** - Baked salmon with roasted sweet potato, broccoli, and a tahini dressing - Chicken and vegetable tray bake with olive oil, garlic, herbs, and quinoa - **Dessert:** Baked cinnamon apples with a spoonful of almond butter - **Drinks:** Water, green tea, herbal tea, black coffee, turmeric latte --- ## Pros The benefits of the anti-inflammatory diet are broad. This style of eating is linked with a lower risk of heart disease, type 2 diabetes, autoimmune diseases and certain cancers. It also measurably (and reassuringly) reduces several markers of inflammation in the body, which are associated with a wide range of chronic conditions.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/39411832/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/34607347/?ref=alphabetguides.com) People with osteoarthritis and rheumatoid arthritis who follow the diet report meaningful reductions in pain and stiffness and other symptoms. There is also some evidence showing benefits for brain health, gut health, mood, allaying fatigue and improving energy levels. Some research suggests it can support fertility and improve outcomes for people with endometriosis.\[[4\]](https://pubmed.ncbi.nlm.nih.gov/34959772/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/32055820/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/35027029/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/39203783/?ref=alphabetguides.com)[\[8](https://pubmed.ncbi.nlm.nih.gov/24428901/?ref=alphabetguides.com)\][\[9\]](https://pubmed.ncbi.nlm.nih.gov/36235567/?ref=alphabetguides.com) The mechanisms behind all of this are well known: the omega-3 fatty acids in [oily fish](https://www.alphabetguides.com/superfood-oily-fish/) (rather than the omega-6), the polyphenols in berries and [olive oil](https://www.alphabetguides.com/superfood-olive-oil/), and the fibre in vegetables and whole grains each play a role in helping control the immune system, its activity, and protecting cells from damage.[\[10\]](https://pubmed.ncbi.nlm.nih.gov/28350517/?ref=alphabetguides.com) From a nutritional standpoint, this diet is excellent. It is built around whole, varied, nutrient-rich foods and aligns closely with what most dietary guidelines around the world already recommend. There are no food groups banned and no [extreme restrictions](https://www.alphabetguides.com/elimination-diet/), which means it provides a broad range of vitamins, minerals, fibre, and healthy fats. It is also a naturally satisfying way to eat — meals are flavourful, [colourful](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/), and filling. ## Cons The main challenge with the anti-inflammatory diet is that it requires a real shift in everyday habits. This is not a [seven-day meal plan](https://www.alphabetguides.com/tag/recipes/) with a clear end date — it is a long-term change in how you shop, cook, and eat. For people who rely heavily on [convenience foods](https://www.alphabetguides.com/ultra-processed-food-diet/), ready meals, or fast food, the change can be overwhelming. Knowing which foods to buy, how to cook them, and how to eat differently from the people around you are all barriers that come up regularly — the learning curve is maybe too steep for some people. For weight loss, the anti-inflammatory diet is not a rapid results quick-fix. It can support modest, gradual weight loss and maintenance of healthy body weight — particularly by cutting out processed foods and added sugars — but it does not come with the structured calorie targets or dramatic early losses that some people look for.[\[11\]](https://pubmed.ncbi.nlm.nih.gov/33266499/?ref=alphabetguides.com) If weight loss is your main goal, you may want to combine this approach with more deliberate attention to portion sizes or [meal timing](https://www.alphabetguides.com/types-of-intermittent-fasts/). The diet also lacks a single definitive guide. Because it’s an “eating pattern” rather than a programme, there is no official rulebook, which means advice varies, and it can be hard to know whether you are "doing it right”, which some people don’t like. --- ## Bottom Line The anti-inflammatory diet is one of the most well-rounded and broadly beneficial ways of eating available. It does not promise dramatic short-term results, but the long-term case for it — across heart health, joint health, brain health, and general disease prevention — is as strong as any dietary pattern out there.[\[12\]](https://pubmed.ncbi.nlm.nih.gov/35334794/?ref=alphabetguides.com) It is nutritionally sound, safe for almost everyone, and flexible enough to fit most lifestyles. If you are looking for a way of eating you can stick with for life, it's one of the best diets to start with. --- ## Overall Score: **★★★★★** - Health Benefits: **★★★★★** - Nutrition: **★★★★★** - Weight Control: **★★★☆☆** - Ease to Follow: **★★★★☆** - Safety Profile: **★★★★★** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

Nutrient deficiencies, muscle loss, and health issues are regularly reported amongst crash dieters. - Outside of professionally supervised medical necessity, crash diets offer little long-term benefit and likely harm your health. Crash diets, rapid weight loss diets, or very low-calorie diets are extreme approaches to dieting. Crash dieters typically consume fewer than 800 calories a day, although some rapid weight loss diets may allow slightly higher intakes. These diets have existed in many forms, often promising quick fixes. Well-known crash diets include juice cleanses, cabbage soup diets, grapefruit diets, meal replacement diets, and several ‘detox’ diets. While there are many different types of crash diets, they all tend to create a large calorie deficit by severely limiting food intake.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/16988070/?ref=alphabetguides.com) This is usually done by restricting the overall intake of all foods, certain food groups, or relying solely on single foods or drinks. Many crash diets are promoted through sensational (but inaccurate) marketing claims, and they tend to go in and out of fashion, just with new names and minor alterations (as a rebrand). They tend to use science-sounding claims like ‘reset metabolism’, ‘flush toxins’, or trigger special fat-burning ‘metabolic states’, and their appeal lies in promises of immediate, visible results without long-term commitment. This can be attractive to people who want to seek quick solutions to ‘[lose weight](https://www.alphabetguides.com/tag/fat-loss/)’ before events, holidays, or when feeling desperate about their body image.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/16988070/?ref=alphabetguides.com) --- ## Example foods and dishes - **Breakfast:** - Meal replacement shake - Half a grapefruit and black coffee - **Lunch:** - Small can of tuna with plain salad (no dressing) - Protein bar and celery sticks - **Snack:** - Ice chips - Single piece of celery - **Dinner:** - Steamed chicken breast (small portion) with steamed veg only - A cup of vegetable soup and salad leaves - **Dessert:** Sugar-free fruit jelly - **Drinks:** Black coffee, diet soda --- ## Pros Crash diets' primary benefit is rapid initial weight loss, which provides immediate gratification and motivation for some people. The dramatic [changes on the scales](https://www.alphabetguides.com/beyond-the-scale/) happen in days and may create a sense of accomplishment and renewed commitment to their body weight goals. For people about to undergo medical procedures, emergency surgery, or specific weight-controlled (sports) events, supervised rapid weight loss may be needed.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/33094956/?ref=alphabetguides.com) Short-term improvements in some metabolic health markers, including better blood sugar and blood pressure control, will likely occur alongside initial weight loss and can provide relief for people with severe metabolic and obesity related issues.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/27002059/?ref=alphabetguides.com) The ‘simplicity’ of many crash diets, consuming only specific foods or following rigid meal plans, eliminates decision-making about food choices, which some people find easier than more flexible diets that require ongoing judgments, decisions and self-control.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/31675146/?ref=alphabetguides.com) ## Cons Severe calorie restriction with limited food variety creates substantial risks for nutrient deficiencies of essential macronutrients, vitamins, minerals, and dietary fibre, which can compromise your health (long-term). While the initial weight loss occurs quickly, maintaining it proves difficult, with most people regaining lost weight, sometimes exceeding their starting weight.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/16988070/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/8002684/?ref=alphabetguides.com) This ‘weight cycling’ or ‘[yo-yo dieting](https://www.alphabetguides.com/yoyo-diet/)' may worsen health outcomes, create psychological distress, and potentially increase long-term weight gain more than maintaining a stable weight. Repeated attempts at crash dieting are also associated with eating disorders, negative body image, unhealthy relationships with food and weight, and other [mental health](https://www.alphabetguides.com/tag/brain-health/) issues.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/8936578/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/8936578/?ref=alphabetguides.com) Physical side effects of crash dieting include: fatigue, weakness, dizziness, headaches, irritability, constipation, hair loss, menstrual cycle irregularity, and, in severe cases, gallstones, dehydration, and heart problems. Loss of muscle comes with rapid weight loss, which reduces your metabolic rate and metabolic health and makes subsequent weight loss (or maintaining weight) more difficult. Practical adherence to a crash diet is poor, which is really a benefit in disguise. The restrictive nature of the diets, the monotonous food choices, hunger, social compatibility, and psychological burden make crash diets unsustainable in the medium to long term.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/31675146/?ref=alphabetguides.com)[\[8\]](https://pubmed.ncbi.nlm.nih.gov/19258409/?ref=alphabetguides.com) --- ## Bottom Line Rapid weight loss comes at a cost: nutritional deficiency, muscle wasting, deteriorating metabolic health, and potentially mental health and eating disorders. Outside of professionally supervised, specific and urgent medical emergencies, crash diets offer little long-term benefit and likely harm your health. Avoid them at all costs. --- ## Overall Score: **★☆☆☆☆** - Health Benefits: **★★☆☆☆** - Nutrition: **★★☆☆☆** - Weight Control: **★☆☆☆☆** - Ease to Follow: **★☆☆☆☆** - Safety Profile: **★☆☆☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

Fad diets represent a broad category of diets that are generally severe, restrictive and unproven. They often promise rapid [weight loss](https://www.alphabetguides.com/tag/fat-loss/) or dramatic health changes. Unlike evidence-based diets developed through scientific research, fad diets typically emerge from commercial interests, celebrity endorsements, or pseudoscientific theories. They gain popularity through sensational marketing claims, or sometimes just marketing (without any specific health claims). Fad diets share a few common features:[\[1\]](https://pubmed.ncbi.nlm.nih.gov/35866077/?ref=alphabetguides.com) - Severely restricted caloric intake (often under 1,000 calories a day) - Elimination of entire food groups - Reliance on single foods or food combinations - Rigid rules without flexibility - Promises of rapid results - Claims related to ‘detoxification’ or miracle cures for fashionable disorders Examples include very low-calorie diets, ‘mono-diets’ (eating only one type of food like grapefruit or cabbage soup), and elimination diets that remove multiple food groups at once; there are also extreme versions of legitimate diets (e.g., ultra-low-carb, ultra-low-fat, ultra-long fasts). The appeal of fad diets usually stems from desperation, as they promise quick solutions for people who are frustrated with diets that take longer to see measurable results. Fad diets use persuasive marketing, exploiting body image concerns, biased testimonials, before-and-after photos, cultural obsession with body image and rapid transformations or glow-ups. Social media has increased exposure to fad diets, particularly among young adults and adolescents who are more vulnerable to the marketing. --- ## Example foods and dishes - **Breakfast:** - Black coffee only - Half an apple - **Lunch:** - Salad with no dressing (just vegetables) - Two plain rice cakes - **Snack:** - Ice chips - Single piece of celery - **Dinner:** - Steamed vegetables only (no oil, no seasoning) - Small piece of boiled chicken breast with plain lettuce - **Dessert:** Low-calorie fruit jelly - **Drinks:** Black coffee, diet soda --- ## Pros Fad diets' only real ‘benefit’ is the potential of rapid initial weight loss, which is only really beneficial for a small group of people under specific circumstances. This can provide immediate psychological gratification and visible results very quickly. The dramatic [change on the scales](https://www.alphabetguides.com/beyond-the-scale/) may create motivation and a sense of accomplishment for those who struggle to control their weight. However, the initial rapid weight loss is largely water and “glycogen” (stored carbohydrate), with some fat and muscle loss.[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5702468/?ref=alphabetguides.com) In rare medical situations, medically supervised very low-calorie diets can be used to treat specific health conditions. The rigid structure and elimination of decision-making can also appeal to some people. The clear rules about what's ‘allowed’ and what’s ‘forbidden’ remove any uncertainty.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/33094956/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/27002059/?ref=alphabetguides.com) For some people, this may feel psychologically simpler compared to more flexible, balanced diets, which require ongoing judgments, decision-making and moderation.[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5841595/?ref=alphabetguides.com) ## Cons Severe restriction of calories and entire food groups creates deficiencies of essential vitamins, minerals, protein, healthy fats, and dietary fibre. Different types of fad diets will naturally create different nutrient deficiencies. Ultra-low-carb diets increase the chances of fibre and certain micronutrient deficiencies. Ultra-low-fat diets reduce fat-soluble vitamins and essential fatty acids. Ultra-low-calorie diets risk widespread micronutrient deficiencies and inadequate protein intake.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/35866077/?ref=alphabetguides.com) Most extreme fad dieters regain lost weight within months, often exceeding their starting weight (‘[yoyo dieting](https://www.alphabetguides.com/yoyo-diet/)’). Some research suggests yoyo-dieting may *worsen* your health, lead to weight gain, and make weight loss more difficult (along with increased risk of developing eating disorders).[\[6\]](https://pubmed.ncbi.nlm.nih.gov/27136388/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/25614199/?ref=alphabetguides.com) Immediate safety concerns include muscle wasting, fatigue, weakness, hair loss, amenorrhoea (i.e., loss of, or irregular, menstrual cycle), gallstones, loss of bone density, anaemia, impaired immunity, and [heart problems](https://www.alphabetguides.com/tag/heart-health/). Sustainability of these diets is also poor, with most people abandoning them within weeks to months. Hunger, monotony, social barriers, the inability to participate in normal eating situations, the cost of specialised foods or programs, and the [psychological burden](https://www.alphabetguides.com/tag/brain-health/) of rigid restriction all affect adherence.[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5841595/?ref=alphabetguides.com) --- ## Bottom Line Most fad diets offer temporary weight loss at a high cost. Nutrient deficiency, muscle wasting, metabolic health, psychological harm, and eating disorders are risks. For most people, fad diets have poor long-term outcomes, poor adherence rates, and notable safety concerns. They’re not advised for general use, if at all. --- ## Overall Score: **★☆☆☆☆** - Health Benefits: **★★☆☆☆** - Nutrition: **★★☆☆☆** - Weight Control: **★☆☆☆☆** - Ease to Follow: **★☆☆☆☆** - Safety Profile: **★☆☆☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

It may require professional oversight. The Ornish diet is a very low-fat, mostly vegetarian eating pattern developed by (and named after) Dr Ornish, a physician from California. It was originally designed in the 1980s not as a weight loss programme but as a tool for reversing [coronary heart disease](https://www.alphabetguides.com/tag/heart-health/), which made it one of the first diets to demonstrate the reversal of atherosclerosis (“blocked arteries”) in a clinical trial.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/9863851/?ref=alphabetguides.com) The diet is based on whole grains, legumes, fruits, vegetables, and egg whites, with [fat restricted](https://www.alphabetguides.com/low-fat-diet/) to roughly 10% of total calories — well below the 30–35% standard dietary recommendations. Red meat, fish, poultry, and most oils are also excluded. Low-fat dairy is permitted in small amounts, so it’s basically a “lacto-ovo” vegetarian diet. The diet is also typically prescribed within a broader lifestyle programme that includes exercise, [stress management](https://www.alphabetguides.com/ways-to-decrease-cortisol/) (yoga, meditation), and social support, which makes isolating the diet's *sole* effects difficult. There are two tiers to the diet: a stricter "reversal" version for people with existing heart disease, and a more moderate "prevention" version for healthy people, but both are basically high in fibre, low in refined sugars, and centred on [plant-based](https://www.alphabetguides.com/tag/plant-based/) whole foods. --- ## Example foods and dishes - **Breakfast:** - Porridge with skimmed milk, sliced banana and flaxseeds - Scrambled egg whites on whole-grain toast with grilled tomatoes and spinach - **Lunch:** - Lentil and vegetable soup with whole-grain bread and a side salad - Brown rice and bean burrito bowl with salsa, lettuce, and fat-free yoghurt - **Snack:** - Sliced apple with a small pot of fat-free cottage cheese - **Dinner:** - Baked white fish with steamed broccoli, brown rice, and a squeeze of lemon - Chickpea and vegetable curry with wholemeal flatbread and (fat-free) raita - **Dessert:** - Poached pears with cinnamon and a spoonful of fat-free yoghurt - **Drinks:** - Water, herbal tea, black coffee, skimmed milk --- ## Pros The strongest evidence for the health benefits of the diet is for treating heart disease. In people with heart disease, the Ornish-style programme reduces the “bad” LDL cholesterol, weight loss, atherosclerosis and reported heart problems. It is probably one of the best-evidenced diets out there for heart health; it is tried, tested and has been around for 50 years.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/38849944/?ref=alphabetguides.com) The diet's focus on whole grains, legumes, and vegetables means it is very high in fibre, provides [adequate protein](https://www.alphabetguides.com/plant-based-protein/) and is low in saturated fat and refined carbohydrates — all properties that align well with cardiovascular health. The prohibition (or limited intake) of animal foods, [processed foods](https://www.alphabetguides.com/ultra-processed-food-diet/), fried and fatty foods also helps heart health. So, for people with existing heart disease who are motivated and have structured support, the Ornish diet programme can produce meaningful improvements that go beyond what most other diets can do. ## Cons Outside of intensive clinically supervised programmes, the evidence isn’t as strong. The health benefits for people without heart disease or cardiometabolic disease are more moderate. It is also difficult to untangle the singular effects of the diet from the other healthy lifestyle changes that are part of the programme ([exercise](https://www.alphabetguides.com/tag/exercise/), low-stress and socialising)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/28758964/?ref=alphabetguides.com) Adherence to the diet has been flagged as an issue, with 80% of people who attempt to follow the diet either giving up or not able to follow it to the letter. This is much lower than similar diets that have similar health and weight loss outcomes.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/17341711/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/18253162/?ref=alphabetguides.com) The diet's severe restriction of fat (including [healthy oils](https://www.alphabetguides.com/superfood-olive-oil/), nuts, and most animal foods) makes it difficult to follow without intensive support; real-world compliance is very low. Very low-fat diets also carry some of their [own health risks](https://www.alphabetguides.com/the-testosterone-diet/) (for some people). Nutritional adequacy is also a concern, with inadequate intake of vitamin E, B12 and zinc reported (due to the low intake of fat and animal foods). The low-fat intake of the diet *may* affect the uptake of the fat-soluble vitamins and some essential fatty acids as well. Carbohydrate intake often exceeds 75% of total calories, well above what most dietary guidelines recommend, which may, in turn, lower the “good” HDL cholesterol and raise triglycerides, which *may* partly offset the LDL-lowering benefits of the diet. This is why [omega-3 fatty acid](https://www.alphabetguides.com/superfood-oily-fish/) supplementation is sometimes recommended for those following the diet.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/18614716/?ref=alphabetguides.com) For weight loss, the diet yields “modest” results, similar to those of other healthy diets, but less than those of specialist weight loss diets. However, if you’re specifically targeting weight loss, aiming to reach a healthy bodyweight, the low adherence and compliance of (and willpower for) the diet need to be considered.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/15632335/?ref=alphabetguides.com) --- ## Bottom Line The Ornish diet has a credible and impressive record of results in supervised clinical heart disease programmes. However, as a standalone dietary pattern for general consumption, it is pretty restrictive, can be nutritionally incomplete and imbalanced without careful planning, and difficult to maintain in the real world. Its benefits appear to depend on the full lifestyle programme rather than *just* the diet alone. For most people, a less extreme but similarly [plant-slant and whole-food](https://www.alphabetguides.com/tag/mediterraneandiet/) approach is likely to produce comparable benefits with better long-term sustainability. --- ## Overall Score: **★★★☆☆** - Health Benefits: **★★★★☆** - Nutrition: **★★★☆☆** - Weight Control: **★★★☆☆** - Ease to Follow: **★★★☆☆** - Safety Profile: **★★★☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

PMID: [15632335](https://pubmed.ncbi.nlm.nih.gov/15632335/?ref=alphabetguides.com) ### Raw Food Diet: A Review URL: https://www.alphabetguides.com/raw-food-diet/ Last updated: 2026-09-19T08:57:52.000Z summary - There are different types of raw food diets, but all are generally based on the premise of eating only uncooked and unprocessed foods. - While some nutrients are indeed degraded by cooking processes (e.g., vitamin C), other nutrients are actually enhanced by it (e.g., protein). - There are several health risks associated with the diet (both long- and short-term), which probably outweigh the potential benefits of the diet. The raw food diet, also known as “raw foodism” or “rawism”, is based on eating uncooked, unprocessed [plant-based foods](https://www.alphabetguides.com/tag/plant-based/). This means that most or all food intake is raw (uncooked) or has been minimally heated. Adherents to the diet believe that cooking destroys essential nutrients, natural enzymes, and ‘life force’ in foods, so raw foods are the answer to promoting health and preventing disease. The diet is based on raw fruits, vegetables, nuts, seeds, sprouted grains, and legumes. Many followers also eat cold-pressed oils, fermented foods (like sauerkraut and kimchi), seaweed, [fresh juices](https://www.alphabetguides.com/juice-diet/), and smoothies. Some variations of the diet include ‘raw’ animal products (e.g., unpasteurised dairy, uncooked eggs, or raw fish). But many raw food diets are actually [vegan or vegetarian](https://www.alphabetguides.com/vegan-mediterranean/). Food preparation for the diet involves methods like blending, juicing, sprouting, soaking, dehydrating, and fermenting foods that are used to preserve the ‘raw state’ whilst creating a variety of textures and flavours. Proponents of the diet argue that our digestive system is evolved for raw foods and that cooking is ‘unnatural’, disrupting the ‘nutrients’ within the food (like the live enzymes, vitamins, and antioxidants). The diet is often adopted for ‘detoxification’, weight loss, improving energy, digestion, [heart health](https://www.alphabetguides.com/tag/heart-health/), and prevention of other common diseases. --- ## Example foods and dishes - **Breakfast:** - Green smoothie with spinach, banana, mango, and almond milk - Raw buckwheat groats soaked overnight with fresh berries - **Lunch:** - Raw vegetable salad with sprouted lentils and tahini dressing - Zucchini noodles with raw marinara sauce and pine nuts - **Snack:** - Raw nuts and dried fruit - Fresh vegetable juice - **Dinner:** - Raw veggie wraps in cabbage with cashew "cheese" - Raw pad thai with kelp noodles, shredded veggies, and almond butter sauce - **Dessert:** Raw cacao balls made with dates and nuts - **Drinks:** Fresh-pressed juice, coconut water, herbal tea --- ## Pros Due to the high intake of fruits and vegetables, raw food diets *usually* provide a good amount of beneficial nutrients (e.g., vitamins B and C, antioxidants, and phytonutrients). The nutrient density of the diet may be the reason why it is linked to lower cardiovascular disease rates and better [mental health](https://www.alphabetguides.com/tag/brain-health/) for some people. Sustained and substantial [weight loss](https://www.alphabetguides.com/tag/fat-loss/) is also reported among those following raw food diets.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/35265657/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/29692750/?ref=alphabetguides.com) This likely results from the diet's inherently [low calorie density](https://www.alphabetguides.com/volumetrics-diet/) (i.e., calories per gram or volume of food), high fibre content, and limited food variety, which reduces overall calorie intake. The elimination of processed foods, added sugars, refined carbohydrates, and too much sodium represents a clear improvement over standard [Western-style diets](https://www.alphabetguides.com/western-diet/). The emphasis on whole plant foods also increases fibre intake, which supports digestive health and gut health. ## Cons Vitamin B12 deficiency is a major concern in the diet, along with increased risks of low calcium, vitamin D, iodine, iron, and zinc, which can go on to affect bone, [brain](https://www.alphabetguides.com/tag/brain-health/), and cardiovascular health.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/25748063/?ref=alphabetguides.com) Many long-term followers of restrictive raw food diets are often underweight, ‘amenorrheic’ (loss of menstrual function), and have low bone mineral density, which suggests there’s inadequate energy and intake of some key nutrients.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/15795346/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/10436305/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/16177198/?ref=alphabetguides.com) Whilst eating food ‘raw’ does preserve some heat-sensitive nutrients, cooking can also *enhance* the nutritional content of many foods by increasing their digestibility and killing harmful bacteria and parasites. There are also safety concerns about food-borne illness, which increase when you consume large amounts of unpasteurised products and raw animal foods.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/25748063/?ref=alphabetguides.com) Despite the name, food preparation can still be time-consuming, as (safely) eating raw foods needs some extra washing, chopping, sprouting, or dehydrating before eating. The limited restaurant options and difficulty sharing meals with others can also be a problem. Some versions of the diet can also be expensive, needing fresh organic produce, some specialised equipment, and some imported or rare ingredients. The diet is pretty difficult to follow, and adherence rates are low, outside of those who are really motivated to do it. --- ## Bottom Line While the raw food diet provides healthy plant nutrients, it increases several health risks (e.g., nutrient deficiency, excessive weight loss, amenorrhoea, bone mass loss), which probably outweigh the potential benefits of the diet. While some nutrients are indeed ‘degraded’ by cooking (e.g., vitamin C and folate), others become more ‘bioavailable’ (like protein, lycopene, beta-carotene, and some minerals), and heat also destroys harmful pathogens and ‘anti-nutritional’ factors in certain foods.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/29692750/?ref=alphabetguides.com) --- ## Overall Score: **★★☆☆☆** - Health Benefits: **★★★☆☆** - Nutrition: **★★☆☆☆** - Weight Control: **★★★☆☆** - Ease to Follow: **★★☆☆☆** - Safety Profile: **★★☆☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

The South Beach Diet is a weight loss program that became popular in the early 2000s. It’s a low-carbohydrate, low(ish)-fat diet that focuses on controlling blood sugar levels. Unlike [ultra-low-carbohydrate diets](https://www.alphabetguides.com/keto-diet/), it positions itself as a moderate, balanced alternative focusing on ‘good’ carbohydrates and fats while restricting processed carbohydrates and saturated fats. The diet gained popularity through its bestselling books and has been marketed as a healthy, sustainable solution for weight loss. It consists of three distinct phases, which progressively become *less* restrictive in nature. 1. **Phase 1,** which lasts two weeks, is the most restrictive phase that eliminates all fruits, grains, and starchy vegetables while increasing intake of lean proteins, non-starchy vegetables, nuts, low-fat dairy, and healthy fats. This phase aims to ‘stabilise’ blood sugar levels, reduce cravings, and promote weight loss. 2. **Phase 2** gradually reintroduces whole grains, most fruits, and vegetables, which continues until your target weight is achieved. 3. **Phase 3** is then the maintenance phase that incorporates all food groups, with continued emphasis on ‘low-GI’ foods and portion control. The diet distinguishes between carbohydrates based on their ‘glycemic index’ (‘GI’), which is basically a measure of how quickly blood sugar is raised. Low-GI ‘good’ carbs include whole grains, legumes, most vegetables, and low-glycemic fruits. Whereas high-GI ‘bad’ carbs include white bread, white rice, potatoes, sugary foods, and refined grains. Similarly, ‘good’ fats like [olive oil](https://www.alphabetguides.com/superfood-olive-oil/), avocados, nuts, and fatty fish are encouraged, whilst ‘bad’ fats (saturated and trans) are limited. --- ## Example foods and dishes - **Breakfast:** - Vegetable frittata with turkey bacon - Greek yoghurt with nuts and stevia - **Lunch:** - Grilled chicken with mixed green salad and balsamic vinaigrette - Turkey & cheese roll-ups with vegetable sticks and hummus - **Snack:** - String cheese and cucumber slices - Hard-boiled eggs - **Dinner:** - Grilled fish with roasted veg and quinoa - Beef tenderloin with cauliflower mash and green beans - **Dessert:** Sugar-free fruit jelly - **Drinks:** Black coffee, unsweetened iced tea, water --- ## Pros Like most low-carb diets, it leads to weight loss and fat loss (in Phase 1). This rapid weight loss can provide motivation and momentum when starting the diet, and may improve adherence to the diet long-term.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/31611148/?ref=alphabetguides.com) Substitution or removal of high-GI carbohydrates is linked to better control of blood sugar and lipid profile. These health improvements, combined with calorie reduction, mean the diet may be particularly effective for type 2 diabetics and those who are already overweight or obese and looking to lose weight.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/33441384/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/25071075/?ref=alphabetguides.com) The diet's phased approach is relatively novel and offers some ‘psychological’ advantages over permanently restrictive plans. The gradual reintroduction of some foods in Phase 2 provides flexibility and may improve adherence compared to prolonged or very low-carb diets. The emphasis on whole foods, lean proteins, vegetables, and healthy fats represents a significant improvement over typical [Western diets](https://www.alphabetguides.com/western-diet/).[\[4\]](https://pubmed.ncbi.nlm.nih.gov/33916669/?ref=alphabetguides.com) ## Cons The benefits of the diet decrease over time, with weight regain and diminishing health benefits reported after a year. Supporting evidence is taken from general low-carb diet studies, limiting confidence in claims that are specific to the South Beach diet.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/33916669/?ref=alphabetguides.com)[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC9621749/?ref=alphabetguides.com) Nutritional concerns also mirror those of other [low-carb diets](https://www.alphabetguides.com/atkins-diet/). Restricting fruits, whole grains, and legumes (Phase 1) will reduce dietary fibre and may limit intake of *some* essential nutrients. Long-term adherence to the diet is typically low, with the restrictive Phase 1 particularly difficult to maintain. Later phases also need ongoing vigilance around food choices.[\[6\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8863186/?ref=alphabetguides.com) Limited food variety (especially in Phase 1) reduces meal satisfaction and may create social barriers at restaurants and gatherings. Compared to some other diets (e.g., [DASH](https://www.alphabetguides.com/dash-diet/) or [Mediterranean diet](https://www.alphabetguides.com/mediterranean-diet-review/)), the South Beach Diet lacks evidence supporting any superior health outcomes or unique advantages of the diet. --- ## Bottom Line Like other low-carb diets, the South Beach Diet offers short-term weight loss and health benefits. However, it lacks any distinctive advantages and any decent long-term supporting evidence. Nutritional limitations, low adherence, and limited direct research suggest it represents a well-marketed low-carb diet variation, rather than a new and novel diet. --- ## Overall Score _This post is for subscribers only._ ### Fasting Mimicking Diet: A Review URL: https://www.alphabetguides.com/fasting-mimicking-diet/ Last updated: 2026-09-22T13:36:33.000Z summary - The fasting-mimicking diet is a 4–7-day-a-month, very low-calorie diet that's designed to trigger "fasting-like" benefits. - Three monthly cycles of the diet reduce body weight, cardiovascular disease risk and inflammation. - Research is still in the early stages, and adherence and safety have been questioned. The fasting-mimicking diet (the “FMD”) is a repeated, short-duration, very low-calorie diet designed to trigger the [biological effects of fasting](https://www.alphabetguides.com/the-fasting-timeline-what-happens-to-your-body-hour-by-hour/) — but without requiring you to stop eating entirely. The diet is typically followed for just 4–7 consecutive days per month, with normal eating on the remaining days. During the FMD days, calorie intake is drastically reduced: around 1,000 calories on day 1, dropping to roughly 700–800 on days 2–5\. The diet is [plant-based](https://www.alphabetguides.com/tag/plant-based/), very low in protein, carbohydrates, and sugar, and (relatively) high in healthy (unsaturated) fats, with micronutrients usually supplemented to cover basic nutritional needs.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/31728501/?ref=alphabetguides.com) The premise behind the diet is that these brief cycles push the body into a fasting-like state that promotes [autophagy](https://www.alphabetguides.com/autophagy-and-fasting/), reduces inflammation, and resets key metabolic markers, before you return to your regular diet. --- ## Example Foods & Dishes - **Breakfast:** - Small bowl of oatmeal with blueberries and a few walnuts - Half an avocado on one rye crispbread with sliced cucumber - **Lunch:** - Vegetable and lentil soup with a drizzle of olive oil - Mixed green salad with cherry tomatoes, olives, and pumpkin seeds - **Snack:** Small handful of mixed unsalted nuts and a few olives - **Dinner:** - Roasted ratatouille (courgette, aubergine, tomato) with olive oil and herbs - Steamed broccoli and cauliflower with a small serving of quinoa - **Dessert:** Small bowl of fresh mixed berries - **Drinks:** Herbal tea, black coffee, water with lemon --- ## Pros Studies in healthy adults show consistent reductions in body weight, body fat, blood pressure, blood sugar, LDL cholesterol, triglycerides, IGF-1 (a growth hormone linked to ageing) and inflammation after as few as three monthly cycles. Effects are strongest in those who have high values to start with — meaning the diet is most effective for those who need it.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/28202779/?ref=alphabetguides.com) In patients with type 2 diabetes, a year-long programme of monthly 5-day FMD cycles reduced blood sugar levels, body weight and lowered the need for diabetes medication. In cancer patients, FMD combined with chemotherapy has shown improvements in tumour response rates, lower growth rates and improvements in some of the side effects of cancer treatments (e.g., vomiting and immune system problems).[\[3\]](https://pubmed.ncbi.nlm.nih.gov/38287649/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/32576828/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/34789537/?ref=alphabetguides.com) For weight loss and maintaining healthy body weights, FMD produces consistent reductions in body fat while preserving muscle mass and [basal metabolic rate](https://www.alphabetguides.com/basal-metabolic-rate/). This is an advantage over continuous calorie-restriction diets, where you often [lose muscle along with fat](https://www.alphabetguides.com/body-recomposition-lose-fat-gain-muscle/), which can be bad for your health. The short, cyclical nature of the diet is appealing and unique, as for most of the month, there are no dietary restrictions whatsoever.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/33420673/?ref=alphabetguides.com) ## Cons The main limitation of FMD is the *relatively* small, short and weak evidence base compared to some other diets (e.g., [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/) or [intermittent fasting](https://www.alphabetguides.com/intermittent-fasting-diet/)). The temporary nature of the diet (i.e., only 5-days) limits the impact that any nutritional deficiencies may have, as long as the normal diet, outside of the FMD, is relatively healthy.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/32223459/?ref=alphabetguides.com) But, like some other fasting protocols, if your [normal diet is poor](https://www.alphabetguides.com/western-diet/), it may exacerbate nutritional deficiencies and lead to health issues. Commercial kits with supplements can be bought to avoid deficiencies, but they are expensive. The FMD is designed to be nutritionally adequate, but the very low-calorie intake makes it unsuitable for some people (e.g., underweight, pregnant, with eating disorders or breastfeeding), and it should only be attempted under medical supervision if you have diabetes, a serious illness, or take regular medication. Adherence is variable. In structured research settings, most healthy people complete the three-day cycle of the diet without difficulty, reporting only mild fatigue, headaches, and hunger. In cancer patients, however, completion rates dropped as low as 20% without intensive support. For a lot of people, even 5 days of severe restriction is challenging; other [types of intermittent fasts](https://www.alphabetguides.com/types-of-intermittent-fasts/) have better adherence and compliance rates. --- ## Bottom Line The fasting-mimicking diet is a short-cycle diet with proven short-term health benefits for a diverse array of people. Its unique “cyclical” programme is one of its greatest strengths: you are not permanently overhauling your diet, just periodically restricting it. However, the evidence remains early-stage, and there are costs to doing it safely (i.e., kits, supplements, and *possibly* medical supervision). It is not a diet for everyone, and it should not be approached as a self-prescribed quick-fix [crash diet](https://www.alphabetguides.com/crash-diet/). --- ## Overall Score: **★★★☆☆** - Health Benefits: **★★★★☆** - Nutrition: **★★★☆☆** - Weight Control: **★★★★☆** - Ease to Follow: **★★☆☆☆** - Safety Profile: **★★★☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

The gluten-free diet eliminates all foods containing gluten, which is a protein found (primarily) in wheat, barley, and rye. Gluten protein is what gives bread and pizza dough their elasticity and helps baked goods maintain their structure. For people with celiac disease (an autoimmune disorder affecting around 1% of people), gluten triggers an immune response that damages their intestinal lining, leading to gut issues. The gluten-free diet emerged as a medical treatment in the 1940s, when a paediatrician observed that the symptoms in children with celiac disease improved when bread was scarce during World War II.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/28948465/?ref=alphabetguides.com) Since then, a gluten-free diet has become the only proven treatment for celiac disease, non-celiac gluten sensitivity, and wheat allergies. However, the diet has also gained widespread popularity among people without any gluten-related reactions; it is often done for perceived health benefits or for [weight loss](https://www.alphabetguides.com/tag/fat-loss/). The diet requires elimination of all sources of gluten (e.g., bread, pasta, cereals, baked goods, and beer made from gluten-containing grains). ‘Hidden’ sources of gluten must also be avoided, such as sauces, processed meats, soups, and cross-contaminated products that may contain it. Foods that are permitted include gluten-free grains (e.g., rice, corn, quinoa, millet), fruits, vegetables, unprocessed meats, fish, eggs, dairy, legumes, nuts, and seeds. There are also specially designed gluten-free products made with alternative flours and starches. However, these [processed options](https://www.alphabetguides.com/ultra-processed-food-an-introduction/) often differ nutritionally from their gluten-containing counterparts. --- ## Example Foods & Dishes - **Breakfast:** - Gluten-free pancakes with maple syrup and bacon - Smoothie bowl with fruit, gluten-free granola, and almond butter - **Lunch:** - Turkey & cheese sandwich on gluten-free bread - Chicken burrito bowl with rice, beans, cheese, and guacamole - **Snack:** - Gluten-free pretzels with hummus - Buttered Popcorn - **Dinner:** - Gluten-free pasta with marinara sauce and meatballs - Grilled steak with baked potato and Caesar salad (gluten-free dressing) - **Dessert:** Gluten-free brownies - **Drinks:** Orange juice, lemonade, coffee --- ## Pros For people with celiac disease and other related conditions, the gluten-free diet provides noticeable and proven benefits. It is the only effective treatment for celiac disease, improving its symptoms, gut health, and gut function. This helps prevent long-term complications associated with the disease (e.g., osteoporosis, infertility, and certain cancers).[\[2\]](https://pubmed.ncbi.nlm.nih.gov/27334430/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/38613039/?ref=alphabetguides.com) When properly followed, the diet allows people with gluten sensitivity to ease most of their symptoms (e.g., diarrhoea, abdominal pain, fatigue, and [brain fog](https://www.alphabetguides.com/tag/brain-health/)). The evidence supporting these benefits is robust and consistent across multiple studies. However, for people without gluten-related intolerances, research does not support any health benefit.[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5866307/?ref=alphabetguides.com) This is an example of where certain diets are great for certain contexts, but have little carryover for anything else. Claims of increased energy, improved digestion, or enhanced [athletic performance](https://www.alphabetguides.com/improve-your-vo2max/) in the general population lack robust evidence. Current research does not support gluten-free diets for people without diagnosed gluten-related disorders.[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6636598/?ref=alphabetguides.com) ## Cons Research shows that gluten-free diets, particularly those relying on processed gluten-free products, are often nutritionally inferior to most conventional diets. Common deficiencies for those who follow the diet include dietary fibre, several B vitamins (thiamine, riboflavin, niacin, and folate), vitamin D, iron, zinc, magnesium, and calcium. Gluten-free processed foods also (typically) use refined starches and contain higher amounts of fat and sugars, meaning increased [calorie density](https://www.alphabetguides.com/volumetrics-diet/).[\[6\]](https://pubmed.ncbi.nlm.nih.gov/27211234/?ref=alphabetguides.com) Weight control concerns are also noted, with studies reporting higher body weights among celiac patients after starting a gluten-free diet. This is potentially due to higher fat and calorie content in gluten-free alternatives. There's no evidence supporting weight loss benefits for the general population, and the diet may contribute to unintended weight gain if not carefully planned. Practical challenges are also an issue as well. Gluten-free products are more expensive and create financial barriers for some people. Cross-contamination risks, limited food availability, and social challenges (e.g., eating out or social dining) can also present problems. --- ## Bottom Line The gluten-free diet is medically necessary and highly effective for people with celiac disease and gluten-related disorders. However, for the general population, it offers no proven benefits and carries risks of developing nutritional deficiencies. It is appropriate only for people with diagnosed gluten-related conditions, who are ideally under professional (medical and dietary) supervision. --- #### Sources 1. Newberry C et al.

But it can be used alongside other treatments. Cardiovascular disease remains the leading cause of death worldwide, and high blood pressure and cholesterol are two of the most prominent risk factors that can be reduced by lifestyle changes. In this article, we’ll look at the effects of intermittent fasting on blood pressure, cholesterol and cardiovascular health. Cardiovascular disease does not usually arrive without a warning. It builds, slowly and quietly, over decades. The increases in blood pressure, worsening lipid and cholesterol profiles, an expanding waist and inflammation are all early signs. All these changes are connected, and rarely occur by themselves. But the good news is that they can be controlled by what and when you eat. Intermittent fasting appears to address several of these cardiovascular health 'risk factors' at the same time. ## Understanding cardiovascular health You’ve probably had your blood pressure measured before. When it's too high (called “hypertension”), it damages your blood vessels, strains your heart, and dramatically increases the risk of heart attacks and stroke. Globally, hypertension is the single biggest cause of early death. It is often called a "silent disease" because it produces no symptoms for years.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC7998524/?ref=alphabetguides.com) Cholesterol, your "lipoproteins", and your blood lipids are slightly more complex. Cholesterol itself is essential — your body uses it to build cell membranes, produce hormones, and synthesise vitamin D. The problem isn’t cholesterol itself; it’s how it's transported. Cholesterol is carried inside lipoproteins, and there are a few types. - Low-density lipoproteins (“LDL” or “bad cholesterol”) carry cholesterol away from your liver. - High-density lipoproteins (“HDL” or “good cholesterol”) carry cholesterol toward the liver, where it gets processed. - Triglycerides (or "TGs") are a type of fat that your blood carries — too much of it is bad for your cardiovascular health. The different amounts of these different types of cholesterol and fats are referred to as your blood lipid profile or panel. Low HDL, high LDL and triglycerides often occur together, which creates an environment that damages your blood vessels over time. Small dense LDL particles, VLDLs (“very low-density lipoprotein”), tend to block your blood vessels and cut off blood and oxygen to your tissues, which keeps them alive. --- ## How does intermittent fasting affect blood pressure? The evidence is pretty consistent: intermittent fasting can measurably reduce blood pressure, most obviously in those who are overweight and are hypertensive. You can expect, on average, a 2-7 mmHg decrease in your systolic pressure (the “top number”) and a 2-4 mmHg decrease in the bottom number (your 'diastolic' pressure).[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC9644535/?ref=alphabetguides.com) Decreased blood pressure occurs even without any weight loss, meaning that intermittent fasting's blood pressure-lowering effects are not just a result of the weight loss. However, it seems that the positive effects of intermittent fasting on blood pressure are not any better than a standard calorie-restricted diet.[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5990470/?ref=alphabetguides.com) They are both effective at lowering blood pressure, but neither is better than the other. So it seems that just reducing the amount of calories (and possibly other things in your diet) is most important.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/38500840/?ref=alphabetguides.com) In the short-term, fasting reduces the amount of sodium your body retains. Sodium loves water, so if the amount of sodium in your blood decreases, the volume of fluid in your blood will also decrease; this, in turn, goes on to decrease your blood pressure. This can occur within days of starting an intermittent fasting protocol.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/33222606/?ref=alphabetguides.com) Over a few months of fasting, fat loss can occur. Some types of fat (“visceral fat”) produce substances that affect how your blood vessels regulate your blood pressure. Inflammation can also impair how your blood vessels keep your blood pressure under control, which intermittent fastingalso decreases as well.[\[6\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC7082272/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/32947129/?ref=alphabetguides.com) ## Does intermittent fasting lower cholesterol and blood lipids? Intermittent fastingappears to meaningfully reduce the “bad” LDL cholesterol levels, the total amount of cholesterol in your blood and increase HDL “good” cholesterol in people who are overweight or obese.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/38500840/?ref=alphabetguides.com) The rare shift from small LDL to the larger HDL is particularly beneficial at reducing cardiovascular disease, and may not always be picked up on standard blood tests. Alongside the overall decrease in cholesterol and the lipoprotein profile shifts, intermittent fastingalso decreases your blood triglycerides. Elevated triglycerides are usually a result of eating too much food, [too much fat and sugar](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/). So it is not surprising that both intermittent fastingand calorie-restriction diets lower your triglycerides. In addition to limiting the quantity (and possibly the type) of foods that you eat, fasting also supports fat loss (including loss of visceral fat and liver fat). Improving the function of your liver is generally good for your cholesterol levels, as it's your liver that helps control how much and what type of cholesterol and fat you have in your system. Intermittent fasting also [improves your insulin sensitivity](https://www.alphabetguides.com/fasting-and-diabetes/). Insulin is a really important hormone which regulates a lot of things in your body. One of them is controlling the amount of triglycerides that are released and cleared from your blood. Better insulin sensitivity generally means you clear triglycerides more effectively from your blood, keeping their levels low. ## Does intermittent fasting reduce cardiovascular disease? So intermittent fastingreduces nearly all cardiovascular disease risk factors: body weight, body fat, visceral and liver fat, blood pressure, cholesterol, LDL and HDL, triglycerides, insulin resistance and inflammation. Improving all of these, all at the same time, in the right way certainly suggests that intermittent fasting reduces the chances of cardiovascular disease. However, there is not as strong evidence showing that it actually reduces cardiovascular disease outcomes (like heart attacks, strokes, or cardiovascular disease deaths). This is not unusual, though. These types of studies are difficult, expensive and take a long time to do properly. It is inferred that if you can improve cardiovascular disease risk factors, you'll also reduce your chances of having or dying from cardiovascular disease. --- ## Intermittent Fasting for Cardiovascular Health in Practice _This post is for subscribers only._ ### Yo-yo Diets: A Review URL: https://www.alphabetguides.com/yoyo-diet/ Last updated: 2026-09-28T10:54:05.000Z summary - Yo-yo dieting is technically known as "weight cycling", which involves phases of intentional weight loss followed by unintentional weight gain. - The diet is ultimately a story of failure. There are basically no health benefits, and yo-yo dieting can actually harm your health in the long run. - Sustainable lifestyle changes, "weight-neutral" healthy diets, and behaviour change seem to produce better outcomes. Yo-yo dieting, also known as ‘weight cycling’, refers to the repeated pattern of intentional weight loss followed by unintentional weight gain. It affects a large proportion of dieters who want to lose weight. The pattern typically involves periods of restrictive dieting leading to weight loss, followed by a return to previous eating habits and then subsequent weight gain, sometimes exceeding the original starting weight. The underlying cause begins with unsustainable dietary restrictions. During the initial period of weight loss, the body lowers its metabolic rate (known as ‘adaptive thermogenesis’). The body also increases hunger signals and food cravings, creating a powerful drive to eat more frequently and regain weight.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/25614198/?ref=alphabetguides.com) Restrictive dieting creates a preoccupation with ‘forbidden foods’, psychological stress, and eventually loss of control or abandonment of the diet. The cycle damages self-confidence and body image, and creates shame and frustration. This may trigger further attempts at even more extreme dietary restrictions, perpetuating the weight ‘cycling’ pattern. --- ## Example foods and dishes - **Breakfast:** - Meal replacement shake - Large stack of pancakes with bacon, eggs, and hash browns - **Lunch:** - Small salad with grilled chicken, no dressing - Fast food value meal with supersized fries & multiple burgers - **Snack:** - Apple slices - Entire bag of chips with a full container of dip - **Dinner:** - Steamed fish with vegetables, no oil - Pizza, wings, breadsticks, & dessert - **Dessert:** - None or sugar-free option - Multiple servings of ice cream, cookies, cake - **Drinks:** Black coffee, water, large vanilla latte, soda, beer --- ## Pros Yo-yo dieting offers virtually no health benefits; it is really a pattern of failure. The only potential benefit is that, for some people, each weight loss phase may temporarily improve *some* health markers (e.g., blood pressure, blood sugar, lipid profile).[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5702468/?ref=alphabetguides.com) However, these improvements disappear upon weight regain, providing no lasting benefit. Because of the potential negative effects of weight-cycling, it is now debated whether it is better to have tried and failed than to have never tried to lose any weight at all. ## Cons Research shows that much of the weight lost from dieting is usually regained within one year, with many people regaining most or all of their weight within five years. Many dieters end up weighing more than their pre-diet weight after repeated yo-yo ‘cycles’.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/27136388/?ref=alphabetguides.com) Some evidence suggests that weight cycling may increase body fat percentage, as weight loss generally involves losing both [fat and muscle](https://www.alphabetguides.com/body-recomposition-lose-fat-gain-muscle/), while the weight regain phase may include regaining a higher amount of body fat.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/38093678/?ref=alphabetguides.com) Some studies also show that weight cycling may worsen metabolic health, appetite, and blood sugar levels. [Mental health](https://www.alphabetguides.com/tag/brain-health/) issues are also well-documented, with weight cycling associated with lower self-esteem, poor body image, increased body dissatisfaction, higher drive for thinness, symptoms of depression and anxiety, a sense of failure and helplessness, and potentially increased chance of having an eating disorder. These mental health issues may be more harmful than the physical ones, particularly in youngsters and women.[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6489475/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/8002684/?ref=alphabetguides.com)[\[7\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5841595/?ref=alphabetguides.com) Nutritional quality during weight cycling is not well studied, but it is likely problematic. If restrictive diets are used during weight loss phases, they are typically nutritionally inadequate, as are diets where weight regain occurs. Repeated cycles of under-consumption followed by periods of over-consumption of [low-quality food](https://www.alphabetguides.com/ultra-processed-food-diet/) likely create nutrient deficiencies. The weight cycling pattern of failure often perpetuates itself. Each failed attempt triggers more extreme restrictions in the next effort. This may create an increasingly unhealthy relationship with food and greater resistance to weight loss with each failed cycle. --- ## Bottom Line Yo-yo dieting represents a pattern of unsuccessful weight control with little health benefit, but it likely decreases long-term health prospects. Rather than repeatedly failing to follow severe restrictive dieting, evidence supports *sustainable* lifestyle changes and weight-neutral health improvements that focus on behaviour rather than just [scale weight](https://www.alphabetguides.com/beyond-the-scale/). --- ## Overall Score: **★☆☆☆☆** - Health Benefits: **★☆☆☆☆** - Nutrition: **★★☆☆☆** - Weight Control: **★☆☆☆☆** - Ease to Follow: **★☆☆☆☆** - Safety Profile: **★★☆☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

But extreme fasts worsen mental health. Fasting triggers several changes in the way your brain functions, so there is interest in how (or if) it affects your 'cognitive function', your mood, brain health and mental health. In this article, we’ll look at whether or not fasting affects your brain and, if it does, how it works. Your brain is the most active, energy-demanding organ in your body, using around a fifth of your body’s energy (despite only being 2% of your body weight). So, as you can imagine, it is very sensitive to changes that go on in your body, like what types of energy are available, changes in your hormones, your environment and inflammation — a lot of things that are affected by fasting. ## Effect of fasting on the brain ### Ketones Under normal conditions, when you’re eating carbohydrates on a semi-regular basis (in your meals), your brain runs almost entirely on a sugar called 'glucose'. When you start fasting, your glucose levels drop, and your body will start to release its own glucose stores (from your liver). But when these stores start to run dry, your body starts breaking down fat, and your liver starts producing 'ketones', which are used for energy. These ketones can get into your brain and can be used for energy to keep your brain working. Ketones aren’t just a “backup" energy source when glucose is in short supply; they appear to have positive health effects on the brain as well.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8954770/?ref=alphabetguides.com) ### "BDNF" Fasting increases substances in your brain called “brain-derived neurotrophic factor” (or “BDNF” for short). It plays a really important role in keeping your brain cells healthy. Low levels of BDNFare associated with depression, poor cognitive function, and some brain diseases (like Alzheimer’s and brain cancer). So, increasing your BDNF levels by fasting is one of the ways it can improve your brain health.[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC7589016/?ref=alphabetguides.com) ### Inflammation Your brain isn’t an isolated, sealed-off organ; it senses and can react to inflammation in your body (even if it is in a distant part of your body). Inflammation is a natural and essential process that helps the body fight and recover from injury or illness. However, there are occasions when your body gets inflamed when it doesn't really need to. It then goes on to cause unnecessary damage to the body (including your brain). Fasting is shown to reduce inflammation, which in turn has been linked to better brain health and mental health (as well as many other diseases).[\[3\]](https://pubmed.ncbi.nlm.nih.gov/37865184/?ref=alphabetguides.com) ### Autophagy Fasting also triggers another natural process called “[autophagy](https://www.alphabetguides.com/autophagy-and-fasting/)” — sometimes referred to as a clean-up job for your cells, which keeps them healthy (most of the time). --- ## Fasting and cognitive performance In young healthy adults, the effects of fasting on the brain’s performance are mixed. Some studies find small improvements in attention or brain processing speed, but other studies found that it actually makes some mental tasks (like memory or endurance tasks) worse.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/24583414/?ref=alphabetguides.com) Short-term fasts or repeated fasts don't seem to reliably produce noticeable changes in your brain’s cognitive performance. A normal, healthy brain is well equipped to go without food for the best part of a day, so you’re unlikely to notice any meaningful change to how you think if the fast is less than 16 hours. Blanket statements about the “brain-boosting benefits” of fasting are not proven (for young, healthy brains anyway). Results for older adults are maybe more positive, particularly those who have experienced cognitive declines already. Researchers reported that intermittent fasting in older adults who already had mild cognitive issues had better chances of reversing their cognitive declines.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/32872655/?ref=alphabetguides.com) Another study found that older adults who ate all their food within a 10-hour time window each day had lower chances of having decreases in their cognitive function.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/33435416/?ref=alphabetguides.com) The same study also found the same results for those who ate breakfast, which seems to favour “early time-restricted eating” as the preferred intermittent fasting pattern for health. So fasting may benefit brains that are ageing and may be in a slightly more vulnerable (lower functioning) state. However, the evidence that fasting can potentially prevent, delay and reverse cognitive declines is promising. ## Fasting and mental health A study of people who did “Buchinger fasts”, which are very long (4 days to 3 weeks), medically supervised fasts where you’re allowed to consume a little bit of food (under 500 calories, usually liquids), reported improved “emotional well-being”. The people who did the fast reported feeling more vigorous, cheerful, calmer and relaxed during it, along with a load of other health benefits. Other studies have shown that regular intermittent fasting is associated with better psychological health, mood and lower rates of depression and anxiety. However, the results aren’t consistent across all people in all situations.[\[7\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6314618/?ref=alphabetguides.com)[\[8\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8470960/?ref=alphabetguides.com) Fasting may not be appropriate for people who are already under high physical or mental stress (e.g., competitive athletes, shift-workers, or those in demanding, dangerous or risky jobs). In fact, fasting may actually worsen their mental health and mood. ## Fasting and brain health Fasting activates several biological processes that are, on paper, good for your brain — we’ve mentioned some of them above. Some studies show that fasting can help people who have brain conditions (like Alzheimer’s, multiple sclerosis, epilepsy and people with mild cognitive impairment). However, in our opinion, the evidence isn’t strong enough yet to recommend fasting to treat people with serious brain diseases or disorders.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8954770/?ref=alphabetguides.com)[\[8\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8470960/?ref=alphabetguides.com) --- ## Putting it into practice _This post is for subscribers only._ ### How Intermittent Fasting Affects Diabetes & Blood Sugar URL: https://www.alphabetguides.com/fasting-and-diabetes/ Last updated: 2026-10-05T08:07:36.000Z summary - Intermittent fasting improves insulin sensitivity and blood sugar control, even without any weight loss or calorie reduction. - Early time-restricted eating (finishing eating by late afternoon) outperforms late eating windows and standard calorie restriction. - A few months of intermittent fasting improves outcomes in people with type 2 diabetes at a level comparable to some medications. The central reason why people get type 2 diabetes is insulin resistance**.** This is when your cells lose their ability to respond to a really important hormone called insulin. Diabetes affects millions of people worldwide and often starts years before symptoms are obvious and a diagnosis is made. This article explains how intermittent fasting can affect your blood sugar levels, insulin levels and your diabetes risk. We’ll also cover what the evidence shows and how to use intermittent fasting to manage it. Type 2 diabetes doesn’t appear overnight; it is a “progressive” disease as your cells’ resistance to insulin slowly and quietly gets worse over time. This is important because it means there is a long window, giving us time to fix it before it becomes irreparable. It seems that intermittent fasting can alter the trajectory of the disease, with a strong body of evidence behind it. ## Insulin, glucose and how things go wrong When you eat carbohydrate you digestive system breaks them [down into sugar](https://www.alphabetguides.com/reduce-sugar-intake/) (otherwise known as 'glucose'). Glucose then enters your blood (which is where it's measured). After it enters your blood, your pancreas reacts and starts releasing insulin, whose main job is to tell your cells to let glucose into them. Your body doesn’t like too much glucose in your bloodstream. So when glucose increases (after you eat), it needs to get rid of it. So it either directs it to your cells to burn for energy, or it stores it in your liver or muscles (as 'glycogen') or in fat tissue (as fat). In a normal, healthy body, this works seamlessly. But if your cells are "insulin-resistant" (usually because they’ve been exposed to too much insulin or you’re too inactive), your body has to store the excess glucose somewhere. What it does is pack it into your fat cells, your organs and any cells that will take it, and it just remains in your blood as well. This isn’t good; it is a temporary solution that actually makes the insulin resistance worse!And if it carries on like this, you’ll end up with type 2 diabetes. Insulin resistance is also associated with other diseases like polycystic ovary syndrome, liver diseases, obesity, and blood vessel diseases.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/29939616/?ref=alphabetguides.com) ## How intermittent fasting helps control blood sugar When you eat, particularly carbohydrate-rich foods, glucose and insulin increase for a couple of hours in a normal, healthy person. And if you fast for long enough, your glucose and insulin levels will then drop. So if you’re eating a typical three-meals-a-day-plus-snacks, your glucose and insulin levels stay elevated for most of the day. So your cells are consistently exposed to insulin during this time, day in, day out. Fasting for a sustained period throughout the day allows your insulin levels to drop and gives your cells a break (both the ones that produce insulin and respond to it). This break seems to make them more “sensitive” to insulin, meaning your pancreas doesn’t need to produce as much insulin in the first place.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/28091348/?ref=alphabetguides.com) Intermittent fastingdoes help with [weight loss and fat loss](https://www.alphabetguides.com/fasting-and-weight-loss/). It can also help lower insulin resistance, reduce strain on your insulin-producing cells, and decrease diabetes risk, even if you don't lose any body weight. So you get double benefits, as it can improve your metabolic health directly and help you lose excess body weight.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/29754952/?ref=alphabetguides.com) ### Visceral fat In addition to general weight loss and fat loss that comes with intermittent fasting**,** it is also effective at targeting a specific type of fat: “visceral fat”, which is stored around your organs and abdomen, and is really unhealthy. Having too much visceral fat causes inflammation, worsens insulin resistance, and is linked to several other diseases.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/34919135/?ref=alphabetguides.com) ### Liver function Your pancreas (insulin-producing organ) gets all the attention when it comes to diabetes and managing your blood sugar levels. However, your liver is also really important as well. Just like eating carbohydrates increases your blood glucose and insulin levels, your liver can also increase your glucose levels by dumping its stored glucose into your bloodstream. Insulin is supposed to stop your liver from doing this. But if your liver cells are insulin-resistant, it ignores this signal. Intermittent fastingcan help correct this by reducing the workload on your liver, your liver fat, and potentially improving its insulin sensitivity. This stops it from dumping glucose into your bloodstream when it doesn’t need to.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/35871650/?ref=alphabetguides.com) ### Circadian rhythm Your body tends to handle glucose better in the morning and afternoon than in the evening. So, eating whilst your body can handle glucose better (rather than later in the day) will lower the strain on your body, as it doesn’t have to work as hard to achieve the same results. This is why early time-restricted eating (eating between 7-8 pm to 3-4 pm) appears to outperform late time-restricted windows, even when calorie and macronutrient intake is the same.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/36702768/?ref=alphabetguides.com) --- ## Intermittent fasting and diabetes risk So intermittent fasting positively affects blood sugar and insulin levels pretty consistently, and it also seems to reduce type 2 diabetes risk. A few months of intermittent fasting is shown to improve diabetes markers and medication requirements in people with type 2 diabetes, which are comparable to the effects of some glucose-lowering medications.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/34620199/?ref=alphabetguides.com) In people with “prediabetes” (at risk of diabetes), six months of intermittent fastingimproves blood sugar control better than those who were following a standard calorie-restricted diet.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/37024596/?ref=alphabetguides.com) In healthy people with no diagnosed metabolic health problems, there are still improvements in some health markers, but they tend to be more modest. So the overall picture is that the worse the person's health, the more profound the effects of intermittent fasting seem to be.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/34919135/?ref=alphabetguides.com) ## What type of intermittent fasting works best? Early time-restricted eating (finishing the eating window by late afternoon) seems to be better than late-night eating windows. Ten-hour and eight-hour time-restricted intermittent fasting eating windows have both been shown to be effective at improving diabetes risk. Likewise, there is also evidence showing that periodic intermittent fasting,like the 5:2 or alternate-day eating pattern, is effective. However, in our opinion, the longer, more demanding fasting protocols are less desirable as there is no consistent daily pattern, blood glucose fluctuations are greater, and some people find them more difficult to follow.[\[9\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC7419159/?ref=alphabetguides.com) ## Putting the Theory into Practice _This post is for subscribers only._ ### Does Intermittent Fasting Work for Weight Loss & Fat Loss? URL: https://www.alphabetguides.com/fasting-and-weight-loss/ Last updated: 2026-09-03T14:31:00.000Z summary - Intermittent fasting leads to weight loss by reducing overall calorie intake. Its results are comparable to calorie-restriction diets. - Shorter, more flexible fasts are generally more effective. So are fasting protocols that start later in the day (e.g., early time-restricted eating). - Intermittent fasts may also improve your health and eating habits, but there are also side effects (e.g., hunger, poor sleep and nutrient gaps). Intermittent fasting is an eating pattern that cycles between periods of fasting and eating, and it's become one of the most studied approaches to [weight and fat loss ](https://www.alphabetguides.com/tag/fat-loss/)over the past decade. But it's not one single approach — there are many types of "timed fasts," which differ in how long they are, how frequent they are, and how they're approached. This can range from daily eating "windows" of just a few hours to water-only fasts lasting months. If you've spent any time researching how to lose weight or burn fat, you've probably come across intermittent fasting. Some people say it transforms your metabolism, burns fat, "resets" your cells and hormones, and "detoxes" your organs. Critics say it's just another type of [calorie-restriction diet](https://www.alphabetguides.com/hara-hachi-bu-an-ancient/), repackaged. Who's right? The answer is somewhere in the middle, leaning more towards the critics' side. Intermittent fasting can be an effective tool for losing weight and burning fat, but probably not for the exact reasons either side claims. ## What Is Intermittent Fasting? [Intermittent fasting](https://www.alphabetguides.com/tag/fasting/) is not a diet in the traditional sense — it doesn't tell you *what* to eat, only *when* to eat it. - "Time-restricted eating" is the mildest and most common form. It compresses your daily calorie intake into a specific window, usually 8–12 hours, which naturally means a 12–16-hour daily fast. Unlike other approaches, time-restricted eating doesn't dictate specific foods or calorie targets; it relies on the smaller eating window to limit total intake. - "Alternate-day fasting" alternates between normal eating days and days of complete abstinence or very low intake (around 25% of normal calories). The 5:2 diet is a popular variation: eat normally five days a week, and restrict to roughly 500 kcal on two non-consecutive days. Alternate-day fasting and time-restricted eating are both "intermittent" fasts, where eating and fasting periods cycle continuously. Beyond these, extended fasting protocols involve complete abstinence from calories for much longer stretches — from 48 hours up to weeks or, in rare cases, months. Each protocol creates a different fasting pattern, but the underlying biology behind them is pretty similar. ## What happens to your body when you fast When you stop eating, your [body starts to change](https://www.alphabetguides.com/the-fasting-timeline-what-happens-to-your-body-hour-by-hour/). Insulin drops, which dials down how much energy you store, releases fat from your fat stores for use as fuel, and shifts you toward burning more fat. Growth hormone increases, helping preserve muscle and stop it from being broken down for energy. Your metabolism effectively switches from burning carbohydrates to burning fat. The longer you fast, the bigger these changes. But even relatively short fasts (12–18 hours) — and even eating a small amount during them (under 500 kcal) — can still trigger these metabolic and [hormonal shifts](https://www.alphabetguides.com/tag/hormones/). More specifically, after eating, your body enters a "postprandial" state, where blood nutrient levels and certain hormones are elevated, and your metabolism is focused on using and storing those nutrients. This state can last 2–6 hours, depending on the meal and the person. After 12–16 hours without food, your body transitions into a "fasted" state, burning more fat for fuel. In between sits the "postabsorptive" state — your body's no longer responding to your last meal but hasn't fully shifted into fasting mode either. This transition is really what separates "restricted eating" from true "fasting," where breaks from food run well over 12 hours. There are further, unique physiological changes when fasts are extended further still (e.g., ketosis), but these aren't typically seen during standard intermittent fasting protocols. Some researchers argue fasting also "cleans up" your cells via a process called [autophagy](https://www.alphabetguides.com/autophagy-and-fasting/), making them function better. Others argue that any health benefits are simply a byproduct of the fat loss itself, which can be achieved through many other methods. --- ## Does it actually work? So you burn more fat while fasting — that's a fact. But does that translate into losing more body fat over time? The short answer: yes. Intermittent fasting can support meaningful fat loss in overweight and obese adults, with people who do it losing about 5–6 kg of body weight over a few months, most of it body fat.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/32060194/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/31023390/?ref=alphabetguides.com) But *how* matters! Most of this weight loss seems to come down to people simply eating less, with their calorie intake dropping by over a third once eating is restricted to a smaller window, no calorie counting required. Fasting, in other words, is really just another form of calorie restriction, applied across a different time frame. Instead of counting calories, you're counting the hours you've fasted (and for some protocols, you might end up doing both). Intermittent fasting doesn't appear to trigger some magical, permanent fat-burning switch, although it does seem to improve [metabolic health](https://www.alphabetguides.com/tag/health/).[\[3\]](https://pubmed.ncbi.nlm.nih.gov/28715993/?ref=alphabetguides.com) The fat loss it produces is meaningful and enough for most people, but it isn't dramatic or life-changing, and may not be sufficient on its own for those who are obese with more serious health issues. That's why we'd classify intermittent fasting as a useful tool rather than a complete transformative solution. ## Intermittent vs. continuous calorie restriction Both intermittent fasting and standard, continuous calorie-restriction diets (eating a little less every day) produce broadly similar weight and fat loss results. That doesn't make intermittent fasting pointless — it's simply another route to the same outcome, another tool in the toolbox.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/29778565/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/30583725/?ref=alphabetguides.com) Among the different intermittent fasting protocols, alternate-day fasting tends to lead to the most weight loss, although it's also the hardest to sustain. Continuous calorie restriction tends to come next, with time-restricted eating trailing slightly behind — though it is generally the easiest to stick with day to day.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/36349432/?ref=alphabetguides.com) One interesting exception: "early" time-restricted eating — where your eating window closes early in the evening (say, 3–6 pm) — has produced better weight loss and some better health outcomes than standard calorie restriction. This may come down to better digestion while you're awake and active, avoiding late-night eating, and aligning more closely with your body's natural circadian rhythms.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/35939311/?ref=alphabetguides.com) ## Beyond fat loss: other health benefits of fasting Intermittent fasting can improve several health markers beyond fat loss, including insulin sensitivity, blood pressure, blood lipid profile, and [appetite hormone](https://www.alphabetguides.com/appetite-and-body-weight/) regulation. Compared to standard calorie restriction, it also doesn't appear to cause any extra loss of muscle — and there's plenty you can do to minimise (or even build) muscle while losing weight.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/33512717/?ref=alphabetguides.com)[\[9\]](https://pubmed.ncbi.nlm.nih.gov/34633860/?ref=alphabetguides.com)[\[10\]](https://pubmed.ncbi.nlm.nih.gov/35443107/?ref=alphabetguides.com) ## Psychology: Pros and cons of fasting for fat loss Compared to other diets, many people find fasting's simple rules easier to follow than weighing, counting, and tracking calories or macros — with intermittent fasting, you're mostly just watching the clock. For those who can stick with it, intermittent fasting appears to naturally limit mindless snacking, late-night eating, and emotional or boredom eating, often with relatively little conscious effort. Clear boundaries and fewer daily decisions can be genuinely appealing. But it isn't the right fit for everyone. Prolonged fasts can bring on hunger, irritability, and trouble with concentration and mood — especially for people who aren't used to fasting yet (these effects often improve with time).[\[11\]](https://pubmed.ncbi.nlm.nih.gov/38500840/?ref=alphabetguides.com) Some people report nausea, low energy, headaches, or gut issues. Fasting can also create social friction around family meals, work events, and social gatherings, and some people notice [poorer sleep](https://www.alphabetguides.com/tag/sleep/) or overeating during their eating window, which can undercut fat loss altogether. There's also a risk of using fasting as a license to eat whatever you want during your eating window, on the assumption that the fast "earned" it. Nutrient-poor [junk food](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/) will offset, or outright reverse, the benefits. If the calorie deficit disappears, so do the results. Intermittent fasting isn't suitable for everyone, and prolonged or more extreme protocols aren't medically recommended for maintaining healthy body weights. Some people should avoid it entirely, or only attempt it under medical supervision — including those who are pregnant or breastfeeding, have a history of eating disorders, are on certain medications, have type 1 diabetes, or are children or teens. --- ## Practicalities: Making it work _This post is for subscribers only._ ### Fasting and Autophagy: What the Evidence Actually Shows URL: https://www.alphabetguides.com/autophagy-and-fasting/ Last updated: 2026-09-22T09:44:32.000Z summary - Autophagy runs continuously. Fasting begins to accelerate it after roughly 16–24 hours, with more pronounced increases beyond 24–48 hours. - More autophagy is not always better — excessive or poorly regulated autophagy is linked to cell death and a complex, dual role in cancer. - Fasting-induced autophagy is real but overhyped. The health benefits of fasting likely occur regardless of how much autophagy changes. Autophagy is a natural process in which you break down and recycle damaged and worn-out bits of your cells that are surplus to requirements. Fasting is known to trigger the autophagy process. In this article, we’ll go through what autophagy is, what the science tells us about when and how fasting activates it, and what it may (and may not) mean for your health. Few biological processes have made the journey from obscure cell biology to mainstream wellness like autophagy has. It now appears on supplement labels, wellness apps, and across social media. But who says it is triggered? How do they know it's triggered? Even if it is triggered, is it even good for your health? Maybe stopping autophagy is better than increasing it? Can you ever have too much autophagy? What does the evidence show? ## What is autophagy? (your cells' built-in recycling system) The word comes from the Greek meaning “self-eating”. It definitely exists. Autophagy is a vital process where your cells identify, break down, and recycle parts that are broken or are not needed anymore. It’s best to think of it as your cell's waste disposal and recycling system, one that has been operating long before you were born. ### What exactly is getting cleared out? - Damaged proteins that have been made incorrectly or no longer function as they should. - Worn-out but once useful parts of your cell, like the parts that make energy or the proteins in your cell. - Waste products, viruses and other harmful debris that shouldn’t be inside your cell. Your cells are efficient. They don’t just throw away all of the old and unwanted material. They break it down to its basic units (like amino acids, lipids, sugars) and use these parts to make new things that your cells actually need. So it’s not just a clean-up system: it is a recycling plant and supply store as well.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/20225336/?ref=alphabetguides.com) Autophagy isn’t turned on or off; it is always active, running in the background all the time. Even if you're eating normally, autophagy is working away in the background, keeping your cells healthy at a normal pace. However, when put under stress (which includes extended fasts), it speeds up how quickly it works.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/37527766/?ref=alphabetguides.com) But whether deliberately increasing it via fasting produces meaningful health benefits is a separate question. --- ## Does fasting-induced autophagy improve human health? When autophagy rates decrease, things tend to go wrong in your cell. And when normal autophagy rates are restored, things seem to improve. However, this doesn’t automatically mean you want to increase autophagy all the time. Autophagy clears toxic proteins that collect in your cells, which have been linked to serious brain diseases (e.g., Alzheimer's, Parkinson's and Huntington's disease).[\[3\]](https://pubmed.ncbi.nlm.nih.gov/23921753/?ref=alphabetguides.com) Autophagy is also thought to play an important role in cancer. In healthy cells, autophagy can take care of tumours by clearing faulty or damaged parts of the cell and the DNA. However, some researchers have also suggested that autophagy can actually help keep cancer cells alive once they’re established. So the “fasting cures cancer via autophagy” is an oversimplification and lacks evidence2. Autophagy helps keep your metabolism working as it should, so it has been linked to metabolic diseases like type 2 diabetes, fatty liver disease and obesity. It has also been linked to ageing, as autophagy rates tend to decline as you age. So it is associated with the build-up of cellular damage that comes with age. However, definitive proof that fasting produces meaningful improvements in health or healthy ageing in humans by restoring normal rates of autophagy has not been proven. ## How fasting triggers autophagy: the mechanism Fasting is widely recognised as a natural trigger of autophagy — this is true. When you eat, your body releases a hormone called insulin, which goes on to tell your body to “grow and make things”. So when insulin is released, your body dials down autophagy rates.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/30172870/?ref=alphabetguides.com) When you eat, your body has enough nutrients coming into its cells, so it doesn’t need to break down and recycle old parts. Why would it bother doing this when it can just use the new incoming ones? So, when you fast, your insulin levels drop, and the autophagy processes are activated. As you continue to fast, the energy levels in your cells start to fall. This sets off another alarm within your cells, telling them that they need to increase autophagy rates again. However, if your cells start getting really low on energy, they'll act to protect themselves and preserve their energy, so they’ll actually shut down the autophagy process itself. So the evidence suggests it is nowhere near as straightforward as: low energy + low insulin = more autophagy. ## When does fasting-induced autophagy start? The short answer is we don’t exactly know. No switch is activated at exactly 16 hours into a fast. Your body isn’t a stopwatch. From animal and cell studies (i.e., not humans), indicators that autophagy is underway have been measured after 24 hours of fasting, but only in some organs, not all of them.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/14699058/?ref=alphabetguides.com) Measuring autophagy in humans is difficult, so the moment at which it becomes more active has not been precisely measured across different parts of the body. By triangulating different pieces of evidence, we can say that autophagy probably starts increasing after 16-24 hours in most people. But no known autophagy switch is turned on in everyone at exactly 16 hours. Research has shown that a group of obese people who followed a time-restricted eating pattern for 6 months increased autophagy more than those who followed a normal eating pattern or who followed a standard calorie-restricted diet!.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/40345145/?ref=alphabetguides.com) So intermittent fasting did seem to increase autophagy, and they seem to coincide with improved health markers (e.g., [weight loss](https://www.alphabetguides.com/fasting-and-weight-loss/), reduced inflammation and cardiometabolic health) ## Can you have too much autophagy? _This post is for subscribers only._ ### Okinawa Diet: A Review URL: https://www.alphabetguides.com/okinawa-diet/ Last updated: 2026-09-22T19:28:02.000Z summary - The Okinawan diet is a traditional diet of the Okinawan Islands. The diet is built on several unique (and healthy) foods and cultural practices. - Okinawans have among the lowest rates of cardiovascular disease and cancer in the world, with naturally low-calorie intakes. - The health benefits are limited to the older Okinawans who followed the diet lifelong, and many traditional ingredients are difficult to source. The Okinawa diet originates from the Okinawa Islands in southern Japan. Historically, the Okinawan islanders had among the longest life expectancies and lowest disease rates in the world (it’s one of the ‘[blue zones](https://www.alphabetguides.com/blue-zone/)’). It’s basically the traditional dietary practices of the older generation of Okinawans.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/18924533/?ref=alphabetguides.com) The diet is [plant-based](https://www.alphabetguides.com/tag/plant-based/) with a high intake of vegetables. Traditionally, Okinawans ate seven servings of vegetables a day, alongside two servings of sweet potato or whole grains and two servings of soy products. The purple-fleshed Okinawan sweet potato (‘beni-imo’) historically served as the staple carbohydrate, which is rich in fibre, vitamins, and ‘anthocyanin’ antioxidants. Other key parts of the diet include [high intake of vegetables](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/) (e.g., seaweed, cabbage, radish), legumes (particularly soybeans in forms like tofu and miso), small amounts of fish (averaging 15-30 grams a day), and low meat, fat, saturated fat, sugar, and refined carbohydrate consumption. The traditional pattern emphasises several ‘functional foods’, which include turmeric (used a lot in cooking), bitter melon (‘goya’), seaweeds, shiitake mushrooms, and jasmine tea. Cooking methods typically involve stir-frying ingredients with a small amount of oil or steaming them. Okinawans follow a distinctive cultural practice called ‘[hara hachi bu](https://www.alphabetguides.com/hara-hachi-bu-an-ancient/)’, which means eating until 80% full and promotes natural caloric restriction without any formal dieting or calorie counting.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/24316687/?ref=alphabetguides.com) --- ## Example foods and dishes - **Breakfast:** - Black coffee or tea (during fasting window, no food) - Water with electrolytes (during fasting window, no food) - **Lunch:** - Large mixed salad with grilled chicken, avocado, nuts, olive oil (breaking fast) - Burrito bowl with rice, beans, meat, cheese, guacamole (first meal) - **Snack:** - Mixed nuts and an apple (during eating window) - Cheese and crackers (during eating window) - **Dinner:** - Salmon with roasted veg and sweet potato - Pasta with meat sauce, salad leaves, and garlic bread - **Dessert:** Ice cream or cookies (during eating window) - **Drinks:** Black coffee, tea, sparkling water --- ## Pros The diet has impressive health benefits, which are most obviously seen in the older Okinawans themselves. Long-term adherence to the diet is linked with low chances of age-related diseases, [cardiovascular disease](https://www.alphabetguides.com/tag/heart-health/) and some cancers, leading to longer and healthier lives.[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5403516/?ref=alphabetguides.com) The diet's cardiovascular health benefits are proven, with low rates of coronary heart disease and stroke among its followers. Emerging evidence also suggests the diet has ‘neuroprotective’ ([brain health](https://www.alphabetguides.com/tag/brain-health/)) effects, leading to lower rates of dementia and better cognitive function as you age.[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5343079/?ref=alphabetguides.com) Lifelong adherence to the diet is also linked with healthier body weights, little weight gain as you age, and low body fat. The diet naturally restricts calories, being around 20-40% lower than a typical [Western diet](https://www.alphabetguides.com/western-diet/). This is thought to occur without hunger due to the high volume of vegetables and dietary fibre in the diet. Some studies using “Okinawa-inspired” diets show weight loss and improved metabolic health markers in type 2 diabetics.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/37867396/?ref=alphabetguides.com) ## Cons Most research involves older Okinawans who maintain these traditional eating patterns throughout their lives. This makes it uncertain whether adopting the diet later in life, or in different people, will produce the same benefits. Other lifestyle, genetic, social or environmental factors possibly contribute to the Okinawans' longevity (besides *just* the diet).[\[6\]](https://pubmed.ncbi.nlm.nih.gov/17986602/?ref=alphabetguides.com) There are also significant practical challenges if you’re going to follow it and you don’t live in Okinawa. Many traditional Okinawan ingredients are difficult to source outside the region (e.g., goya, seaweed, beni-imo). There is also cultural unfamiliarity with preparation methods, long preparation times for some of the dishes, and the acquired taste for certain foods may also make it difficult to follow. There are also concerning trends inside the region, with the diet declining in popularity even among Okinawans themselves. Younger Okinawans have adopted Westernised diets featuring increased meat consumption, [processed foods](https://www.alphabetguides.com/ultra-processed-food-diet/), and eating fewer vegetables. This ‘modernisation’ has coincided with deteriorating health markers and reduced life expectancy in Okinawa, raising questions about the diet's sustainability or suitability in the modern world. It remains uncertain whether the diet can be successfully used to control healthy body weights and cardiometabolic health outside of older Okinawans.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/18924533/?ref=alphabetguides.com)[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5403516/?ref=alphabetguides.com) --- ## Bottom Line The traditional Okinawan diet is strongly linked with longevity and healthy ageing, though the observations may reflect a combination of dietary, genetic, and lifestyle factors of the older Okinawan generations. There are also practical challenges, with limited high-quality evidence showing it works outside (or sometimes within) the region. The declining adherence even in Okinawa suggests it functions best within its original cultural and environmental context, rather than as a universally applicable diet. Nevertheless, the diet in itself is difficult to fault and offers several (healthy) unique eating habits that are not found elsewhere. --- ## Overall Score: **★★★★☆** - Health Benefits: **★★★★☆** - Nutrition: **★★★★☆** - Weight Control: **★★★☆☆** - Ease to Follow: **★★☆☆☆** - Safety Profile: **★★★★★** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

Some education and support are required to optimise adherence. The Therapeutic Lifestyle Changes (TLC) diet is a “heart-health” first diet programme. It’s specifically designed to lower cholesterol and reduce cardiovascular disease risk. It was created as a ‘holistic’ lifestyle programme, which also gives recommendations on diet, [physical activity](https://www.alphabetguides.com/tag/exercise/), and managing body weight. The diet is based on balanced macronutrients with specific targets: - Less than 7% of daily calories from saturated fat - Less than 200 mg of dietary cholesterol a day - Less than 2.3 grams of sodium a day - Only enough calories to achieve or maintain a healthy body weight - Total fat intake is capped at 25-35% of total calories - Replacing saturated fats with healthier fats (e.g., monounsaturated and polyunsaturated fats). - 10–25 grams of soluble fibre daily - Two grams of plant stanols/sterols (optional to reduce cholesterol). - Lean proteins (e.g., skinless poultry, fish, lean cuts of meat) - [Low-fat or fat-free](https://www.alphabetguides.com/low-fat-diet/) dairy products (2 to 3 servings a day) - Whole grains (at least 6 servings a day) - Legumes (3 to 5 servings a day) - Fruits (2 to 4 servings a day) - Vegetables (3 to 5 servings a day) - Nuts and [healthy oils](https://www.alphabetguides.com/superfood-olive-oil/) (in moderation). - Fatty meats, full-fat dairy, egg yolks, tropical oils (e.g., coconut, palm), hydrogenated oils containing trans fats, and fried foods are to be avoided. The TLC diet doesn't eliminate entire food groups; it instead focuses on portion control and healthier food choices. --- ## Example foods and dishes - **Breakfast:** - Skimmed milk porridge with berries & ground flaxseed - Whole-grain cereal with skim milk & banana - **Lunch:** - Whole-wheat Turkey breast sandwich, mustard, lettuce, tomato, & low-fat soup - Grilled chicken breast with brown rice & steamed veg - **Snack:** - Apple with a small handful of almonds - Low-fat yoghurt with berries - **Dinner:** - Baked salmon with quinoa pilaf & steamed broccoli - Lean beef with baked sweet potato & mixed green salad - **Dessert:** Fresh fruit salad - **Drinks:** Green tea, water, skim milk --- ## Pros The TLC diet has excellent [cardiovascular health](https://www.alphabetguides.com/tag/heart-health/) benefits. Several studies have shown that it decreases LDL cholesterol and total cholesterol in people with high cholesterol. Modest improvements in blood sugar are reported, particularly for people with type 2 diabetes. Short-term reductions in inflammation have also been reported.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/11861668/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/37352395/?ref=alphabetguides.com)[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6212867/?ref=alphabetguides.com) The TLC diet has high nutritional quality, balanced macronutrient intake, adequate fibre, and adequate micronutrients. The emphasis on whole grains, legumes, [fruits and vegetables](https://www.alphabetguides.com/tag/plant-based/) provides vitamins, minerals, antioxidants, and phytonutrients, with minimal risk of any nutritional deficiency. The TLC diet has reported no safety concerns, and the diet’s flexibility and adaptability are good for real-world use for many people.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/26077375/?ref=alphabetguides.com) ## Cons Weight loss outcomes for the diet are modest and probably insufficient for people wanting to lose a large amount of weight. There are more effective diets for those who are targeting [weight loss and fat loss](https://www.alphabetguides.com/tag/fat-loss/). The cardiovascular health improvements for those following the diet are consistent but moderate. More restrictive, specialised diets can produce better health benefits in less time, although these are often at the cost of sustainability and safety. The TLC diet's conservative approach prioritises long-term gains and sustainability over quick results.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/37352395/?ref=alphabetguides.com) The diet is designed for practicality. Whilst it’s probably more sustainable than highly restrictive diets, real-world adherence rates remain uncertain. The diet requires sustained behaviour change, careful food selection, and ongoing attention to saturated fat and cholesterol intake.[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5580624/?ref=alphabetguides.com) This could be challenging for people accustomed to [convenience foods](https://www.alphabetguides.com/ultra-processed-food-diet/) and eating out. Success typically depends on nutrition education, meal planning skills, and a supportive environment that may not be available for everyone. --- ## Bottom Line The TLC diet is a safe, nutritionally sound, evidence-based approach for reducing cholesterol and cardiovascular disease risk. Its moderate, balanced approach supports long-term adherence and sustainability. Although the results remain modest, it is still well-suited for people who want to prioritise and improve their cardiovascular health and have access to professional guidance. --- ## Overall Score: **★★★★☆** - Health Benefits: **★★★★☆** - Nutrition: **★★★★★** - Weight Control: **★★★★☆** - Ease to Follow: **★★★★☆** - Safety Profile: **★★★★★** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

This 7-day high-protein plant-based meal plan is designed for anyone who wants to follow a plant-based diet without compromising on their protein (and their intake of other nutrients). We’ve got ideas for protein-rich breakfasts, quick and easy dinners, and convenient snacks. ## How much protein do you need on a plant-based diet? One of the most common concerns about switching to a plant-based diet is protein. It is a reasonable concern — protein is essential for [building and repairing muscle](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/) and supports your health. The daily target for most adults is around 0.8g per kilogram of body weight, though active individuals and older adults likely benefit from eating more protein (1-2g per kg per day). A well-planned plant-based diet *can* [meet your protein needs](https://www.alphabetguides.com/plant-based-protein/). Unlike animal proteins, most plant proteins are lower in digestibility, missing or low in at least one essential amino acid, and have a low amount of protein per calorie or gram of food ('protein density'). This means choosing the right plant foods, eating a wide enough variety, and using simple preparation techniques to release the protein (more easily) from what you eat. --- ## 7-day high-protein plant-based meal plan ## Day 1 ### Breakfast: Tofu scramble Crumbled firm tofu cooked with turmeric, nutritional yeast, and black salt, loaded with bell peppers and spinach. The result looks and tastes similar to scrambled eggs. It is high in protein, iron, and B vitamins. Black salt (kala namak) is the secret ingredient (but optional if you can’t find it). Serve with toasted whole-grain bread or warmed tortillas. ### Snack: Salted edamame Steamed edamame pods sprinkled with flaky sea salt. This snack is a high-quality protein source delivering around 17g per cup, along with iron and folate. For convenience, keep a bag of frozen edamame in the freezer. It takes under three minutes to prepare and beats any packet of crisps or chips for nutrition and flavour. ### Lunch: Lentil and quinoa bowl Cooked green lentils and quinoa layered over leafy greens with roasted sweet potato, pickled red cabbage, and a lemon-tahini dressing. Because lentils supply lysine (where quinoa doesn’t) and quinoa covers methionine (where lentils don’t), this bowl provides a complete amino acid profile in a single dish. ### Dinner: Tempeh stir-fry with brown rice and sesame Marinated tempeh cubes stir-fried with broccoli, snap peas, and red pepper in a ginger-tamari sauce, served over brown rice. Tempeh is a fermented soy product that delivers 19g of protein per 100g, is more digestible than most plant proteins (similar to animal proteins), and, unlike a lot of [plant foods](https://www.alphabetguides.com/blue-zone/), it develops a golden crust when cooked in a hot pan. ![Person holding black frying pan with fried rice.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1601226809638-4ab838bb4d97.jpeg) ### Ingredients (serves 2) - 200g firm tempeh, cut into 2 cm cubes - 1½ cups (280g) cooked brown rice - 1 tbsp neutral oil (sunflower) - 1 tbsp sesame oil - 2 garlic cloves (minced) - 1 tsp fresh ginger (grated) - 1 head broccoli (in small florets) - 1 red bell pepper (thinly sliced) - 100g snap peas - 3 tbsp low-sodium soy sauce or tamari - 1 tbsp rice vinegar - 1 tsp sesame oil (to finish) - 1 tsp maple syrup - 1 tsp cornflour + 1 tbsp water ### Directions 1. Whisk together soy sauce, rice vinegar, maple syrup, and cornflour slurry in a small bowl. Set aside. 2. Heat neutral oil in a wok or pan over high heat. Add tempeh and cook for 4–5 minutes, turning until it turns golden and crispy all over. Remove and set aside. 3. In the same pan, heat sesame oil over medium-high heat. Add garlic and ginger; stir-fry for 30 seconds until it has softened slightly. 4. Add broccoli and peppers. Stir-fry for 3–4 minutes until just tender but still crisp and colourful. Add the snap peas and cook 1 minute more. 5. Return tempeh to the pan. Pour over the sauce and toss to coat. Cook 1–2 minutes until the sauce thickens and starts to cling to the other ingredients. --- ## Day 2 ### Breakfast: Peanut butter overnight oats with hemp seeds Rolled oats soaked overnight in soy milk with two tablespoons of peanut butter, a tablespoon of chia seeds, and a scattering of hemp seeds. Top with sliced banana and a drizzle of maple syrup in the morning. This dish requires zero morning effort and delivers over 20g of protein before you’ve started your day. ### Snack: Roasted spiced chickpeas Crispy oven-roasted chickpeas seasoned with smoked paprika, cumin, and garlic powder. This crunchy, high-fibre snack provides 15g of protein per serving. Make a double or triple batch: they keep in an airtight container for three days and are better than anything store-bought. ### Lunch: Black bean and sweet potato burrito bowl Seasoned black beans, roasted sweet potato, brown rice, quick-pickled jalapeños, guacamole, and fresh salsa in a bowl. Finished with lime juice and a handful of fresh coriander. Do not skip the lime — it brightens everything up and improves the absorption of iron from the beans.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/12936926/?ref=alphabetguides.com) ### Dinner: Red lentil dal with wilted spinach A warming, aromatic red lentil dal tempered with mustard seeds, cumin, garlic, and ginger, finished with fresh spinach and lemon. Red lentils deliver 18g of protein per cooked cup, require no soaking, and cook in under 20 minutes. This makes this dish one of the fastest and most nutritious dinners in the plan. ![Red lentil dal with roast vegetables and greens.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1596560314766-08c0c6890024.jpeg) ### Ingredients (serves 2) - 1 cup (200g) dried red lentils, rinsed - 2½ cups (600ml) vegetable stock - 1 tbsp coconut or neutral oil - 1 medium onion (finely diced) - 3 garlic cloves (minced) - 1 tsp fresh ginger (grated) - 1 tsp cumin seeds - ½ tsp mustard seeds - 1 tsp ground coriander - 1 tsp ground turmeric - ½ tsp chilli flakes (adjust to taste) - 1 can (400g) chopped tomatoes - 100g fresh spinach - Juice of ½ lemon - Fresh coriander and naan bread to serve ### Directions 1. Heat oil in a medium saucepan over medium heat. Add cumin and mustard seeds; cook 30–60 seconds until they pop. 2. Add onion and cook 5–6 minutes until softened and lightly golden. Stir in garlic, ginger, ground coriander, turmeric, and chilli flakes. Cook 1 minute. 3. Add chopped tomatoes. Cook 2–3 minutes, stirring. Add rinsed lentils and vegetable stock. Stir, bring to a boil, then reduce to a simmer. 4. Simmer uncovered for 15–18 minutes, stirring occasionally, until lentils break down and the dal is thick. Add a splash of water if needed. 5. Stir in spinach and let wilt for 1–2 minutes, then remove from heat, add lemon juice, and season with salt. Top with fresh coriander. Serve with naan. ### Chef's tip Make double the quantity — red lentil dal keeps in the fridge for 4 days and actually improves the flavour. It also freezes great for up to 3 months, making it a good candidate for meal-prep Sundays. --- ## Day 3 ### Breakfast: Edamame and spinach smoothie bowl A thick, bright green smoothie blended from frozen edamame, baby spinach, banana, soy milk, and hemp seeds, topped with granola, sliced kiwi, and a swirl of almond butter. Edamame in a smoothie sounds unusual, but it blends completely smooth, giving it a creamy texture, and adds [**protein**](https://www.alphabetguides.com/tag/protein/) without altering the flavour. ### Snack: Almond butter and apple slices Sharpe and crispy apple slices paired with two tablespoons of natural almond butter. Simple, portable, and provides around 7g of protein alongside healthy fats and fibre. Choose a natural almond butter with no added sugar or palm oil for the cleanest nutritional profile. ### Lunch: Chickpea 'tuna' salad sandwich Mashed chickpeas combined with nori flakes, finely diced celery, red onion, lemon juice, and vegan mayonnaise on toasted whole-grain bread. The nori is the key ingredient — it lends a subtle taste of the sea that makes this a novel lunchbox staple. ### Dinner: Seitan with roasted root vegetables and herb sauce Thick slices of pan-seared seitan with a herb-mustard crust, served over caramelised roasted carrots, parsnips, and beetroot, covered with a fresh parsley and caper salsa verde. At 25g of protein per 100g, seitan is the densest plant protein around. ### Ingredients (serves 2) - 300g store-bought seitan (sliced thickly) - 2 tbsp olive oil - 1 tbsp Dijon mustard - 1 garlic clove (minced) - 1 tsp dried thyme - 1 tsp smoked paprika - 2 medium carrots (cut into chunky pieces) - 2 medium parsnips (quartered) - 1 medium beetroot (cut into wedges) ### Directions 1. Preheat oven to 200°C / 180°C fan / Gas 6, then toss root vegetables in olive oil, rosemary, salt, and pepper. Spread on a large tray and roast for 30–35 minutes until tender and caramelised, turning halfway. 2. Mix olive oil, Dijon mustard, garlic, thyme, smoked paprika, salt, and pepper. Brush all over the seitan. 3. Heat a dry pan over medium-high heat. Cook seitan 3–4 minutes per side until golden with charred edges (just like a slice of meat). 4. Make the herb sauce: blitz parsley, capers, garlic, olive oil, and lemon juice in a small blender until roughly textured and season. You can also do it in a pestle and mortar if you don’t have a blender. 5. Plate roasted vegetables, top with seitan, and spoon the herb sauce generously over everything. Serve immediately. ### Chef's tip Soak the cashews overnight in the fridge to save time. For a nut-free version, substitute the cashew crema with plain soy yoghurt thinned with lime juice and a pinch of garlic powder. --- ## Day 4 ### Breakfast: Savoury chickpea flour pancakes (“besan chilla”) Thin, crispy Indian-style pancakes made from chickpea flour batter with fresh ginger, green chilli, coriander, and cumin, served with soy yoghurt and a spoonful of mango chutney. These come together in under 15 minutes, deliver 12g of protein before the yoghurt, and keep you full until lunch. ### Lunch: White bean, kale and lemon soup A Tuscan-inspired broth where creamy cannellini beans, cavolo nero, and garlic simmer together, finished with a squeeze of lemon and a swirl of good [olive oil](https://www.alphabetguides.com/superfood-olive-oil/). Make a large pot as the beans release their starch overnight and transform the broth into something thick and savoury by the next day. ### Dinner: Tofu tikka masala with basmati rice Marinated extra-firm tofu, charred in a hot pan, simmered in a rich, smoky tomato-coconut tikka sauce and served over white or brown basmati rice. Press the tofu for at least 30 minutes before marinating; a drier surface absorbs more flavour, develops a better crust, and holds together in the sauce. ![Tofu curry with basmati rice.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/07/photo-1588166524941-3bf61a9c41db.jpeg) ### Ingredients (serves 2) - 400g extra-firm tofu (pressed for 30 min) - 3 tbsp plain soy yoghurt - 1 tbsp lemon juice - 1 tsp each: cumin, coriander, smoked paprika, garam masala - ½ tsp each: turmeric, chilli powder - 1 tbsp coconut or neutral oil - 1 medium onion (finely diced) - 3 garlic cloves (minced) - 1 tsp grated ginger - 1 can (400g) chopped tomatoes - 150ml full-fat coconut milk - 1 tsp maple syrup - 1 cup (185g) uncooked white or brown basmati rice ### Directions 1. Cut pressed tofu into 2 cm cubes. Combine the marinade ingredients, coat the tofu thoroughly, and marinate for at least 30 minutes. Cook brown basmati rice per packet instructions. 2. Heat a non-stick pan over high heat. Fry the marinated tofu 2–3 minutes per side until charred and golden. Set aside. In the same pan, heat oil over medium heat. Add onion and cook 6–7 minutes until softened. 3. Add garlic, ginger, garam masala, cumin, smoked paprika, and chilli powder. Cook 30 seconds. 4. Add tomatoes. Simmer 8 min, stirring, until the sauce deepens in colour. 5. Stir in coconut milk and maple syrup. Simmer 3 minutes until silky and rich. Add the charred tofu. Stir gently and simmer 2 minutes. Serve over rice with fresh coriander. ### Chef's tip Press the tofu using a dedicated tofu press or place it between two plates with a heavy pan on top for 30 minutes. The drier the surface, the better the marinade will penetrate the tofu — and the better the crust when it hits the pan. ### Dessert: No-bake dark chocolate and walnut energy balls Medjool dates blended with rolled oats, cocoa powder, chopped walnuts, and peanut butter, rolled into balls and chilled until firm. A no-bake snack or dessert that doubles as a protein-rich energy source. Roll in desiccated coconut or crushed pistachios for a more polished finish. Make a full batch of 12 and store it in the fridge for the week. --- ## Day 5 _This post is for subscribers only._ ### Low FODMAP Diet: A Review URL: https://www.alphabetguides.com/fodmap/ Last updated: 2026-09-21T18:03:03.000Z summary - The FODMAP diet removes "fermentable" carbohydrates to identify and manage food triggers for IBS and other gut problems. - The diet is shown to reduce abdominal pain and bloating and improve quality of life for people with IBS symptoms. - However, it is complex to follow and may lead to other health problems if it is not done properly (i.e., with professional guidance). The low-FODMAP diet is designed to manage the symptoms of irritable bowel syndrome (IBS) and other gut health issues. ‘FODMAP’ is an acronym for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. These are all basically types of carbohydrates that aren’t absorbed into your body very well, so they end up fermenting in your gut. The diet was developed by researchers at Monash University (Australia) in the early 2000s, based on the understanding that (for some people) FODMAPs draw water into the gut and produce gas (through fermentation). In turn, this leads to gut issues such as bloating, abdominal pain, diarrhoea, and constipation. The diet is typically conducted in three phases.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/28592442/?ref=alphabetguides.com) 1. **'Elimination' Phase:** Involves avoiding high-FODMAP foods for 2-6 weeks. This includes avoiding certain fruits (e.g., apples, pears, watermelon), vegetables (e.g., onions, garlic, cauliflower), grains (wheat, rye), legumes, lactose dairy products, and sweeteners (e.g., honey, high-fructose corn syrup). During this phase, dieters are encouraged to consume low-FODMAP foods instead (e.g., bananas, oranges, carrots, potatoes, rice, quinoa, lactose-free dairy, and maple syrup). 2. **'Reintroduction' Phase:** Then tests individual FODMAP groups to identify triggers. This is done to create a long-term ‘modified’ FODMAP diet that only restricts problematic foods. 3. **'Personalisation' Phase:** This means following a unique or personalised FODMAP diet, which means only avoiding foods that trigger symptoms. This is done to maximise dietary variety and flexibility of the diet whilst minimising symptoms. --- ## Example foods and dishes - **Breakfast:** - Scrambled eggs with spinach & [gluten-free](https://www.alphabetguides.com/gluten-free-diet/) toast - Porridge made with lactose-free milk and blueberries - **Lunch:** - Grilled chicken salad with lettuce, cucumber, carrots, and olive oil dressing - Rice noodles with shrimp, bok choy, and ginger - **Snack:** - Lactose-free yoghurt with strawberries - Rice crackers with cheddar cheese - **Dinner:** - Grilled salmon with roasted potatoes and green beans - Turkey meatballs with gluten-free pasta and tomato sauce (no garlic/onion) - **Dessert:** Dark chocolate (small portion) - **Drinks:** Peppermint tea, water, lactose-free milk --- ## Pros The low-FODMAP diet works well for improving IBS symptoms. Several high-quality studies show that the diet reduces abdominal pain and bloating and improves quality of life for most people with IBS.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/29336079/?ref=alphabetguides.com) When properly supervised (by a qualified dietician), you can get all essential nutrients from low-FODMAP foods alone. The diet is also generally safe, with minimal negative effects. There is also some evidence suggesting potential benefits for other gastrointestinal conditions, such as inflammatory bowel disease. The structured, phased approach of the diet allows for personalisation, allowing you to expand the content of the diet while managing symptoms at the same time.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/34376515/?ref=alphabetguides.com) ## Cons The low-FODMAP diet presents some practical and nutritional challenges. It is quite complicated to follow and will probably (for most people) require professional support to do it correctly. The FODMAP content of different foods isn't intuitive and requires a lot of research (or oversight/supervision). Prolonged or unsupervised restriction of FODMAP foods can *potentially* increase the risk of deficiencies (e.g., fibre, calcium, iron, zinc, folate, and certain vitamins).[\[4\]](https://pubmed.ncbi.nlm.nih.gov/31947991/?ref=alphabetguides.com) The diet's restrictive nature reduces food diversity and may negatively impact your gut microbiome, though long-term effects are unknown. Adherence to the diet can also be difficult due to higher food costs, limited availability of suitable products, and problems when dining out or attending social gatherings.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/31586453/?ref=alphabetguides.com) Long-term safety data are limited, with most studies focusing on short- to medium-term outcomes. The diet is not recommended for people with (or at risk) of eating disorders, as its restrictive structure may exacerbate problems. Without proper guidance through the reintroduction phase, there is a risk that people may unnecessarily restrict foods, which could compromise nutrition, health outcomes, and quality of life. --- ## Bottom Line The low-FODMAP diet is an evidence-based, effective intervention for managing IBS and some other gut issues. However, it is not easy to follow, and (without professional supervision) there’s potential for nutrient deficiencies. This limits its practicality. So we think the diet is best suited for people who have IBS with medical oversight. --- #### Sources 1. Staudacher HM, Whelan K.

This can produce noticeable physical, sexual, and behavioural symptoms. - The andropause can be reversed. Weight loss, resistance training, good sleep, and diet can restore testosterone without medication. - Maintaining a healthy bodyweight is the single most effective thing you can do — excess body fat converts testosterone to oestrogen. The ‘andropause’, also called the ‘male menopause ’, is the gradual decrease in testosterone that some men experience as they age. In this article, we’ll go through what it is, its symptoms, diagnosis, treatment and how it affects your body and quality of life. Unlike female menopause, where estrogen decline is largely irreversible, much of what drives declining testosterone in men is linked to things you can change: your body weight, lifestyle, diseases and [how you sleep](https://www.alphabetguides.com/tag/sleep/). There are many things you can do. It can be delayed, prevented or even reversed. ## What exactly is andropause? It is a set of symptoms plus a decline in testosterone, which occurs as you get older. It is medically referred to as ‘late-onset hypogonadism’, which is when your (previously fully functioning) testicles don’t produce enough testosterone to meet your body’s needs. Andropause refers to the cluster of symptoms and hormonal changes associated with declining testosterone levels in ageing men. It is formally known as late-onset hypogonadism ("LOH") in the medical literature — a condition where the testes produce insufficient testosterone to meet the body's needs, in men who previously had normal testicular function.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/24407185/?ref=alphabetguides.com) Whereas female menopause is a (relatively) quick and almost complete loss of their estrogen-producing capacity, andropause is slower and less dramatic. Testosterone is said to decrease in some men by 1-2% a year from their mid-30s onwards. So by the time a man reaches his 50s or 60s, levels may have dropped enough to cause noticeable changes.[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3770846/?ref=alphabetguides.com) In addition to ageing, andropause can be driven by obesity, poor health, diseases, and many other lifestyle decisions, which means it can be (partially) delayed, prevented or reversed. In fact, many men (who generally maintain a healthy body weight and good health) can maintain their testosterone levels throughout their life and won’t experience andropause. Twenty percent of men who are over 70 years old have low testosterone levels. But more thorough assessments have suggested that 2% of men over 40 are andropausal. ## Symptoms of andropause Symptoms tend to develop gradually, which is why they often go unrecognised for years. Many men attribute the changes to stress, poor sleep, or simply "getting older." The most common symptoms include: ### Physical symptoms - Loss of muscle mass and strength, even with regular exercise - Increased body fat, particularly around the abdomen - Reduced energy and persistent fatigue - Decreased bone density (raising long-term fracture risk) - Reduced body and facial hair - Hot flushes and sweating (less common, but reported in some men) - Enlarged or tender breast tissue (‘gynaecomastia’) ### Sexual and reproductive Symptoms - Reduced libido (or sex drive) - Erectile dysfunction or difficulty maintaining erections - Reduced semen volume - Decreased testicular size - Reduced fertility (though complete infertility is uncommon) ### Psychological and cognitive symptoms - Low mood, irritability, and increased anxiety - Difficulty concentrating and mental fogginess - Reduced motivation and drive - Poor sleep quality and insomnia - Loss of confidence and sense of well-being ## How is andropause diagnosed? No single symptom is a diagnosis on its own. The pattern and combination of many of these symptoms, alongside blood testosterone test results, is what confirms the diagnosis. There is no single “gold-standard” test at the moment. A single low total testosterone reading doesn’t necessarily indicate that you’re going through andropause. Clinicians will administer a few tests and examine several markers in conjunction with total testosterone (e.g., free testosterone, sex hormone-binding globulin, luteinizing hormone, follicle-stimulating hormone, prolactin, thyroid function, and blood glucose). These are taken to confirm you have low T and help deduce the cause of it.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/29562364/?ref=alphabetguides.com) Andropause isn’t the easiest condition to diagnose, as there are a lot of (common) conditions that have similar symptoms. Fatigue, low mood and reduced libido are also seen in men with depression, thyroid problems, sleep apnoea and anaemia. This is why clinical assessment is needed for proper diagnosis. ## Effects of andropause on the body ### Physical health Low testosterone in men is associated with increased cardiovascular disease risk, type 2 diabetes, obesity, osteoporosis, [low muscle mass](https://www.alphabetguides.com/testosterone-and-muscle-growth/) (‘sarcopenia’), fragility, frailty and fractures.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/32469467/?ref=alphabetguides.com) ### Mental health and brain health Men with low testosterone have an increased risk of depression, anxiety, and reduced quality of life. Many men anecdotally report that they have low drive (to do things), enthusiasm for life or “flatness” without having depression.[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3770846/?ref=alphabetguides.com) ### Fertility Testosterone is needed to produce sperm. So, men with low testosterone tend to have low sperm volume and quality, although they are generally *not*completely infertile.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/29562364/?ref=alphabetguides.com) ## Treatment of the Andropause For men whose andropause is caused by poor lifestyle habits (e.g., diet, activity, body weight), they can restore their testosterone levels and improve their symptoms and quality of life, usually without any medication.

But you'll need high motivation and to get over a learning curve. The vegan diet excludes all animal products, including meat, poultry, fish, seafood, eggs, and dairy products. It’s the most restrictive form of vegetarianism, and it’s followed for many reasons that aren’t health-related (e.g., ethical concerns, animal welfare, environmental impact, sustainability, religious beliefs). Veganism has gained popularity in recent years, with the growing availability of plant-based alternatives (making it easier to follow) combined with growing mainstream appeal coming from a variety of sources. The diet relies entirely on [plant foods](https://www.alphabetguides.com/tag/plant-based/): vegetables, fruits, legumes (e.g., beans, lentils, peas), whole grains, nuts, seeds, and plant-based oils. Modern vegan diets tend to include processed foods like plant-based milks (e.g., soy, almond, oat), meat substitutes (e.g., tofu, tempeh, seitan), dairy-free cheeses, and egg substitutes. Nutritional yeast, fortified foods, and supplements are commonly used to fill nutritional gaps like vitamin B12. The nutritional profile of the diet provides a large amount of fibre, phytonutrients and antioxidants. It is low in saturated fat (when whole food-based), zero cholesterol, and has a [low calorie density](https://www.alphabetguides.com/volumetrics-diet/). The diet's macronutrient distribution varies a lot, from high-carbohydrate whole-foods to high-fat (e.g., nuts, seeds, oils) vegan diets. --- ## Example foods and dishes - **Breakfast:** - Tofu scramble with mixed veg & whole grain toast with vegan butter - Porridge with almond milk, chia seeds, berries, & maple syrup - **Lunch:** - Chickpea salad sandwich with lettuce & tomato on whole grain bread - Buddha bowl with quinoa, roasted veg, tahini dressing, & tempeh - **Snack:** - Hummus with crudités & pita chips - Trail mix & dark chocolate - **Dinner:** - Lentil bolognese, whole wheat pasta with nutritional yeast - Black bean & sweet potato taco, guacamole & cashew “sour cream” - **Dessert:** Vegan chocolate chip cookies - **Drinks:** Black coffee, tea, sparkling water ## Pros Vegan diets have clear [cardiovascular health](https://www.alphabetguides.com/tag/heart-health/) benefits. Research shows lower heart disease and improved blood lipid profile (i.e., lower total and LDL cholesterol) for vegans. These benefits likely result from eliminating dietary cholesterol, reducing saturated fat intake, and increasing fibre and plant food intake.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/37226630/?ref=alphabetguides.com) Several studies have shown weight loss for those following [vegan diets](https://www.alphabetguides.com/vegan-mediterranean/) compared to omnivores, particularly in overweight or obese people and type 2 diabetics. The diet's high fibre content, low energy density, and its favourable effects on your gut microbiota probably contribute to its health benefits.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/35672940/?ref=alphabetguides.com) Vegans typically maintain lower body weights compared to omnivores, and the metabolic health improvements include better blood sugar control for type 2 diabetics and prediabetics. Studies show the diet reduces inflammation, and some evidence indicates lower rates of certain cancers.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/26853923/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/37962057/?ref=alphabetguides.com) ## Cons The diet creates a risk of inadequate intake of vitamin B12, vitamin D, calcium, zinc, iodine, and selenium without careful planning. Vitamin B12 supplementation is essential. Bone health problems also arise from several nutrient inadequacies.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/33341313/?ref=alphabetguides.com) Some research suggests vegans may have lower bone density and potentially higher fracture risk (likely due to insufficient calcium, vitamin D, and high-quality protein intake). These risks require proactive planning through fortified foods and supplementation.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/27886704/?ref=alphabetguides.com) Protein quality and quantity may also be inadequate without [careful planning](https://www.alphabetguides.com/plant-based-diet-meal-plan/). While total protein intake can meet recommendations, [plant proteins](https://www.alphabetguides.com/plant-based-protein/) generally have lower digestibility and sub-optimal amino acid profiles compared to animal proteins. So this may require eating a variety of different plant foods throughout the day. Practical challenges include limited food options in many social settings, restaurants, and travel options, which make the diet difficult to follow. Long-term adherence rates are typically low, likely due to social eating limitations, increased meal planning demands, higher costs for speciality products, and the need for dietary supplements. The increasing availability of highly processed vegan products (sometimes called 'vegan junk food'), while improving convenience, can also compromise nutritional quality. Replacing healthy foods with ‘vegan junk foods’ can potentially offset any health benefits.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/37450568/?ref=alphabetguides.com) --- ## Bottom Line Eliminating animal products reduces intake of *some* things that can worsen your health (e.g., saturated fat, dietary cholesterol, and potential contaminants like hormones and antibiotics). Increasing your intake of plant foods also provides fibre, essential nutrients and protective ‘phytonutrients’. So, well-planned vegan diets can offer cardiovascular and weight loss benefits, with some reduced risk of other diseases. However, supplementation, careful nutrient planning, and monitoring for deficiencies are also required, making the diet suitable for motivated people who are willing to invest in nutrition education and ongoing dietary attention — the health benefits may not be enough alone. --- ## Overall Score: **★★★☆☆** - Health Benefits: **★★★★☆** - Nutrition: **★★★☆☆** - Weight Control: **★★★☆☆** - Ease to Follow: **★★★☆☆** - Safety Profile: **★★★★☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- --- #### Sources 1.

Legumes lack methionine. Grains and seeds lack lysine. You should combine them. - Plant proteins are not as "bioavailable" as animal proteins. Vegans should probably have protein targets a bit higher (\~25%) than recommended. - Soy, tempeh, tofu, buckwheat, quinoa, and amaranth are the only common plant foods with near-complete amino acid profiles. Plant-based protein sources are foods from plants (like legumes, grains, seeds, and vegetables), which supply the protein your body needs to build, repair, and thrive. In this article, we’ll explain why protein matters, what the issues are with the plant-based diet, and which everyday plant foods give you enough (high-quality) protein. More people are shifting away from meat and dairy. Some people want better health. Some may want to economise and save money. Others may want to reduce their environmental impact or just don’t like eating animals. But whatever the reason, a common question that consistently comes up is: Can you really get enough protein from plants? The short answer is yes. But it’s not as easy and requires some know-how. Plant proteins are different to animal proteins: they are generally harder to digest, contain less protein, and are missing some essential nutrients (one or more of the “essential amino acids”). ## Why do you need protein? Protein is made up of amino acids**.** It is these amino acids that go on to make things your body needs (like new [muscle](https://www.alphabetguides.com/tag/muscle/), skin, organ cells, hormones, enzymes and immune cells). Your body can make some amino acids itself (these are called “nonessential” amino acids) when you need them. But there are some that your body can’t make (these are called “essential” amino acids), which someplants don’t have (but all animal proteins do). Getting enough protein is not just about [muscle](https://www.alphabetguides.com/back-to-basics-a-checklist-for-muscle-growth/). Protein is needed for hundreds of other things that keep you healthy. Signs that you’re not getting enough protein include:[\[1\]](https://pubmed.ncbi.nlm.nih.gov/32806532/?ref=alphabetguides.com) - Fatigue that doesn't get better with rest - Poor recovery from exercise and muscle weakness - Poor recovery from illness or frequent illnesses - Brittle nails and hair loss - Difficulty concentrating In children and teenagers, not eating enough protein can stunt growth and brain development. So, researchers generally recommend getting at*least*0.8 grams per kg of body weight a day. ## Why go on a plant-based diet? “Plant-based diets” can range from flexitarian (mostly plants with the occasional animal foods, like the [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/)), to vegetarian (no meat but can eat dairy and eggs), to vegan (no animal products at all). Research consistently links intake of [plant foods](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/) to reduced risks of several diseases, including all the big killers (cardiometabolic disease and cancer).[\[2\]](https://pubmed.ncbi.nlm.nih.gov/30318102/?ref=alphabetguides.com) Plant-based diets are also generally cheaper and have less impact on the environment. However, there’s no way to cut it; the fewer animal products that you eat, the more difficult it is to ensure you are getting enough high-quality protein. So flexitarians need to pay less attention to their diet than vegans do. But you*can*stillmeet all your protein needs, even on a strict vegan diet. ## Plant-based diet protein problems ### Problem #1\. “Protein density” Many plant foods are nutritious, but simply don’t contain a lot of protein. For example, spinach and broccoli contain protein, but in such a small amount that you’d need an enormous portion to meet your daily needs. You’d need to eat 4 large bags of spinach and four whole heads of broccoli to get 30 g of protein! Generally, a food needs to have at least 12% of its calories from protein to be called a “source of protein”. We’ve got some listed in the table below. ### Problem #2\. Amino acid profile Animal proteins contain all nine [essential amino acids](https://www.alphabetguides.com/amino-acids-muscle/) in the right amounts. However, most plants are missing at least one essential amino acid, usually either “methionine” or “lysine”. Legumes (like beans, peas, and lentils) are missing methionine, while grains, seeds and nuts are missing lysine. It doesn’t matter if you eat enough of the other eight essential amino acids (or more than you need); even if you are deficient in one of them, your body cannot make the things it needs — it’s the so-called “weakest link effect”.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/33599941/?ref=alphabetguides.com) ### Problem #3\. Digestibility and bioavailability Even if the plant foods you’re eating contain enough protein (and essential amino acids), your body may not be able to digest and absorb all of it. For most animal foods, you tend to absorb nearly all of the amino acids in their proteins. Whereas with plants (in their natural state), your body doesn’t digest and absorb as much. Some of the proteins in the plants are difficult to get to, as they are protected by other things found in them. They don’t give up their amino acids as easily as animal foods do.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/32806532/?ref=alphabetguides.com) ## Optimising protein on a plant-based diet _This post is for subscribers only._ ### 9 Ways Poor Sleep Damages Your Health URL: https://www.alphabetguides.com/sleep-and-health/ Last updated: 2026-09-22T09:45:17.000Z summary - Sleeping under 6 hours makes you more than four times more likely to catch a cold and can halve your antibody response to vaccines. - Four hours of sleep for six consecutive nights impairs blood sugar control to a level comparable with early-stage type 2 diabetes. - One week of poor sleep reduces testosterone by 15% in healthy men, and long-term poor sleep can reduce it by up to 30%. ## How much poor sleep does it take to damage your health? Poor sleep affects virtually every part of your body, and it affects your health far beyond just feeling tired. This article goes through how sleep quality and duration affect nine different parts of your health. Consistently sleeping poorly quietly accelerates disease, disrupts your hormones, compromises your immunity, and shortens life expectancy: it operates under the cover of night, largely outside our awareness. --- ## #1\. Poor sleep and your immune system Sleep affects your immune system. When you sleep, your body makes immune cells that help you fight infection and keep your body healthy. Studies show that poor sleep can impair *both* of your main immune systems: the one you are born with (“innate immune system”) *and* the one you acquire over time by being exposed to things ('pathogens') in your environment (your “adaptive immune system”).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/22071480/?ref=alphabetguides.com) The consequences are real. People who sleep less than six hours a night were over four times more likely to get a cold compared to those who slept over seven hours a night. Just a couple of extra hours seems to make a difference. There have also been consistent studies showing that people with sleep deprivation have weaker protective 'antibody' responses to taking vaccines (like hepatitis and flu jabs).[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4531403/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/36917932/?ref=alphabetguides.com) In some cases, it means they are less than half as effective at protecting you against infection. It seems to happen because your sleep-suppressed immune system doesn’t respond as well to the vaccine. Poor sleep also tends to shift your body into a “pro-inflammatory” state, meaning it produces substances that damage parts of your immune system that it uses to fight infections. So you start to create an environment in your body that is both “inflamed” (high-inflammation) *and* “immunocompromised” (poor immune function). That is a recipe for disaster. Your body doesn’t like this, and being in this state for too long has been linked to a load of serious long-term health conditions (e.g., cardiovascular disease, metabolic disease and cancer). --- ## #2\. Poor sleep and heart disease risk Studies have shown that not sleeping enough can increase your risk of heart disease by nearly 50%. Poor sleep raises blood pressure, disrupts the nerves that keep your cardiovascular system in check, increases inflammation, atherosclerosis, “bad” cholesterol, triglycerides and visceral fat, and reduces your “good” cholesterol. Circadian misalignment, which means irregular sleep times, even if you’re getting your eight hours a night, will also affect your heart health. We have a full article on the effects of poor sleep on your [cardiovascular health](https://www.alphabetguides.com/sleep-and-heart-health/) if you want to read more about it. --- ## #3\. Poor sleep and gut health Your gut and your sleep are connected via the “gut-brain axis”, which is your nervous system and your internal “circadian” body clock. Your gut “microbiome” (the trillions of bacteria in your gut) can affect your digestive system, and just like you, they also have their own bacterial “body clock". This means that different types of bacteria are active at different times of the day. Disrupting the circadian rhythm of your gut bacteria can potentially affect your gut health.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/25417104/?ref=alphabetguides.com) Sleep deprivation can also disrupt your nervous system, which goes on to affect your gut 'motility', which is the control of the muscular contractions that move food through your gut. Reduced motility slows transit, causes constipation, increases [gas production](https://www.alphabetguides.com/fodmap/), and causes pain and bloating. Many poor sleepers tend to report these symptoms, but rarely link their gut issues to their sleep. Your microbiome is very responsive to sleep deprivation, altering it within just a week of poor sleep. Studies show poor sleep reduces the ratios between the “good” and the “bad” gut bacteria.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/27900260/?ref=alphabetguides.com) These ratios go on to affect your immune system, brain chemistry (like serotonin and GABA) and help control inflammation — meaning that disrupting them can have other negative effects on your health, not just in your gut. More bad news. Poor gut health can go on to make your sleep even worse. So, it’s a vicious circle. Poor sleep wrecks your gut, and poor gut health wrecks your sleep! Pain, discomfort, bloating, and a disrupted microbiome (called “dysbiosis”) will all affect your sleep. --- ## #4\. Sleep, mental health and the brain As you probably know already, a single bad night’s sleep can affect your mood, emotions, memory and cognitive performance. Sleep deprivation doubles the risk of depression and anxiety disorders. Consistent poor sleep affects your brain chemistry, rewires your brain networks (not in a good way), and eventually it starts to damage your brain. Poor sleep in midlife also increases your risk of dementia. Bad news all round, really! So, we have a full article on the ways that poor [sleep affects your mental health and brain health](https://www.alphabetguides.com/sleep-and-your-brain/), if you want to read more about it. --- ## #5\. Poor sleep and type 2 diabetes risk Ahealthy person who sleeps for four hours (or less) for six consecutive nights can impair their ability to control their blood sugar levels, similar to that of someone with early-stage type 2 diabetes. Both how much andhow well you sleep are associated with increased risk of having type 2 diabetes.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/10543671/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/19910503/?ref=alphabetguides.com) 💡 Sleeping too much (over 9 hours) is also a risk factor as well, so there is a balance. Sleep deprivation impairs your ability to transport your blood sugar into your cells (in your liver, muscle and fat tissue cells), which then go on to burn or store it. This happens because poor sleep blunts your “insulin sensitivity” to carbohydrates, which keeps your blood sugar levels high for too long (not good for your health). Poor sleep also increases your [cortisol levels](https://www.alphabetguides.com/what-is-cortisol/), which tells your liver to start dumping stored carbohydrates into your blood as well. So your blood sugar levels can remain high even if you’re [fasting](https://www.alphabetguides.com/the-fasting-timeline-what-happens-to-your-body-hour-by-hour/) or not eating a lot of carbohydrates. Cortisol also increases your appetite for unhealthy junk foods and promotes the storage of visceral fat (around your organs), which also makes your insulin sensitivity (and health) worse! The good news is that some of these negative effects can be reversed if you’re able to [fix your sleep](https://www.alphabetguides.com/fix-your-sleep-schedule/). It won’t happen in one night, but you can offset some of the negative effects by consistently getting enough sleep. --- ## #6\. How poor sleep makes you fatter Poor sleep drives weight gain in ways which are beyond your conscious control. Sleep deprivation disrupts the hormones that control hunger and fullness (ghrelin and leptin). It does this while increasing your cravings for [calorie-dense junk foods](https://www.alphabetguides.com/how-to-avoid-upfs/). Not getting enough sleep can increase daily calorie intake by up to 500 kcal. You also tend to be lazier when you don’t sleep as well (you move less). It also decreases the amount of fat that you burn and makes you store fat more easily, especially “visceral fat” around your organs (the worst kind of fat!). In addition to making you heavier and fatter, poor sleep will also impair your ability to build muscle if you’re trying to tone certain parts of your body by lifting weights. --- ## #7\. Poor sleep and cancer risk Melatonin is a “sleep hormone” that’s produced when it starts to get dark. It regulates your body clock and tells your body that it's time to sleep. Interestingly, it also has anti-cancer properties and supports your immune system, keeping your cells working as they should (not developing tumours).[\[8\]](https://pubmed.ncbi.nlm.nih.gov/19095474/?ref=alphabetguides.com) Poor sleep, work, stress and exposure to bright lights at night can suppress your melatonin production, and then go on to make your sleep even worse. Shift workers who work against their body’s natural clock (called “circadian misalignment”) and are regularly exposed to light-at-night have higher rates of several different cancers and lower immune system function.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/23137527/?ref=alphabetguides.com) Your immune system is really important as it helps fight the early formation of cancer cells. So a sleep-deprived state of low melatonin, low immunity, high cortisol, and high inflammation creates an environment for cancer to develop. So, in addition to general recommendations for [improving sleep](https://www.alphabetguides.com/how-to-sleep-better/), complete, uninterrupted darkness may be particularly important for cancer prevention. --- ## #8\. Poor sleep and testosterone Poor sleep suppresses testosterone. Just one week of poor sleep can reduce your [testosterone levels](https://www.alphabetguides.com/testosterone-and-muscle-growth/) by 15% in young healthy men. Regular poor sleep can suppress it further (up to 30%), which is the equivalent of ageing 10-15 years in men. This happens because your testosterone levels tend to peak while you sleep, so disrupting sleep will also disrupt your testosterone production. The sleep-deprivation-induced increase in cortisol also suppresses your testosterone levels.

Poor sleep and life expectancy _This post is for subscribers only._ ### How to Cut Your Workout Time Without Sacrificing Gains URL: https://www.alphabetguides.com/cut-your-training-time/ Last updated: 2026-10-11T12:43:31.000Z summary - Muscle growth begins after as few as two sets, but returns diminish beyond 10–12 sets. So 2–10 sets a week is most time-efficient. - Complex sets, compound exercises, specific warm-ups, machines, shortening rest times, and planning your sessions can also save time. - Reps lasting 1–2 seconds produce the same muscle growth as 8-second reps. Slowing the rep tempo beyond that provides no additional benefit. Resistance training is one of the most effective ways to build muscle, develop strength, and protect your long-term health — but it doesn't have to take over your schedule and the rest of your life. In this article, we’ll go through seven evidence-based resistance training ‘hacks’ that can save you time without compromising gains. By using a few of these strategies, you should be able to get your workout sessions down to about 30 minutes. Most people who want to start weightlifting but tend to avoid it say the same thing: they don’t have enough time. Traditional gym lore tells you you need 90-minute workouts, 6 days a week, with 30-40 sets a session with dozens of exercises, so it’s understandable why many people stay away from it. That version of training is really reserved for a select few elite athletes, who would probably get the same (or possibly better) results by reducing their training load. They’re probably training for a completely different reason and purpose than you are, so why copy them? Muscle growth and strength gains are driven by a [handful of things](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/): volume (how much you train), effort (how hard you train) and consistency. Each of these can be achieved in a surprisingly short window of time when you do the right things. Here are seven ways to get the most out of training for the least amount of time. ## #1\. Train with the most efficient dose ### Estimated time saved: 20-30 minutes Training ‘volume’ is the total number of sets completed per muscle group and probably the primary driver of muscle growth. More volume generally means better gains, but returns start to diminish after a certain point.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/35291645/?ref=alphabetguides.com) The evidence seems to suggest this is around 10-12 sets per muscle group. Beyond this point, you tend to accumulate fatigue more than growth. Research also shows that as few as two sets per muscle group are needed to stimulate meaningful growth. Traditional gym programmes often prescribe 3–6 sets per exercise across 3-5 exercises for the same muscle group, so up to 30 sets total. This is more than most people need, especially for beginners and intermediate lifters. A “[minimalist approach](https://www.alphabetguides.com/minimalist-muscle-growth/)” of 2-6 sets per muscle group per week, performed to a high level of effort, produces meaningful results. In practice: instead of doing 4 sets of three different variations of the same chest exercise, pick 2 exercises and do 2 sets on each. ## #2\. Choose the 'right' exercises ### Estimated time saved: 5-10 minutes Not all exercises are equal when it comes to ‘time efficiency’. Multi-joint (“compound”) exercises work across two or more joints, engaging several muscle groups simultaneously. This means more muscle is trained per set, so you need to do fewer exercises overall. Compare a barbell back squat to a leg extension machine. The squat loads your quads, glutes, adductors, lower back, hamstrings, calves and abs simultaneously. Whereas the leg extension only works one muscle group at a time: the quads.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/22373894/?ref=alphabetguides.com) Similarly, select [bilateral exercises](https://www.alphabetguides.com/unilateral-exercise/) where both limbs work at the same time (e.g., bench press, barbell row, deadlift) rather than single-leg or single-arm exercises; these take twice as long to do, and there doesn’t seem to be any extra benefits.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/8876751/?ref=alphabetguides.com) If you’re really tight on time, pick exercises that don’t take a lot of time to set up or warm up for. Dumbbell, cable and machine-based exercises are just as effective for muscle growth (compared to free-weight barbell exercises); and you can (generally) get through these types of exercises a bit quicker. However, the best exercise is also one you can perform safely, confidently, and without a long wait for equipment.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/32358310/?ref=alphabetguides.com) ## #3\. Cut your rest time — but smartly ### Estimated time saved: 5-10 minutes Rest between sets is not wasted time; you need to rest between sets. Shortening it too aggressively will affect your performance and, in turn, your growth. However, you can also rest for far longer than necessary. One to three minutes of rest between sets is optimal for most exercises. Heavier ‘compound’ lifts may benefit from up to 3 minutes. Most people don’t need five.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/26605807/?ref=alphabetguides.com) The most effective way to use rest time is the ‘agonist-antagonist superset’, which pairs exercises that work opposing muscle groups. For example, biceps curls followed immediately by triceps pushdowns, or a bench press followed by a row. Because one muscle group rests while the other works, no formal rest period is needed between them. Research shows that it doesn’t affect your training performance, but saves you a lot of time6. If full supersets don't suit your session, you can still use rest productively. Use your rest period to warm up for your next exercise, or adjust your weight or set up the equipment for it. These small tweaks will reduce dead time without interfering with your recovery between sets. ## #4\. Use time-saving set techniques ### Estimated time saved: 5-10 minutes _This post is for subscribers only._ ### How Sleep Affects Your Cardiovascular Health URL: https://www.alphabetguides.com/sleep-and-heart-health/ Last updated: 2026-09-22T09:45:54.000Z summary - Both sleeping under 6 and over 9 hours per night is linked to cardiovascular disease; 7–8 hours a night is the good sleep target to hit. - Blood pressure normally drops 10–20% during sleep, but failure to dip increases cardiovascular risk regardless of your daytime lifestyle habits. - Adults sleeping under 6 hours ate approximately 550 more calories per day and had more artery-clogging than normal sleepers. Cardiovascular disease is the leading cause of death worldwide, by far, and poor sleep is one of its most overlooked and underappreciated causes. This article covers how sleep affects your heart health, from blood pressure and inflammation to cholesterol, weight gain, and blood vessel health. When looking at things you can change, diet, [exercise](https://www.alphabetguides.com/exercise-lowers-blood-pressure/), medication, and smoking habits are the first port of call (and rightly so). However, sleep rarely gets a mention, despite the solid evidence linking it to cardiovascular health. We now know how bad sleep insidiously damages your heart and blood vessels — night by night, year by year. ## Sleep and cardiovascular health: the evidence Several studies have linked 'sleep duration' (hours of sleep per night) to cardiovascular health, showing that both short (under 6 hours) and long sleep duration (over 9 hours) are predictors of getting or dying from cardiovascular disease. So we’re back to the 7-8 hour sleep-a-night target as the sweet spot for cardiovascular health.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/21300732/?ref=alphabetguides.com) The effects of poor sleep on cardiovascular disease are similar to those of being physically inactive; so it's not a trivial effect either. But, because it’s a completely different question and set of causes, in this article, we’re going to focus on the more common (and easier solved) problem of sleeping too little and sleeping poorly rather than sleeping too much. ## How does sleep affect blood pressure? Blood pressure follows a somewhat predictable pattern throughout the day in healthy people; it *dips* when you sleep by about 10-20%. Why? Well, scientists think it gives the body a window to rest its heart and blood vessels that have been working hard throughout the day. In some people, blood pressure fails to fall enough (or at all) when they sleep. People who don't have decreases in their blood pressure when they sleep have an *increased* risk of cardiovascular disease, irrespective of how healthy they are or whatever they choose to do during the day. Sleep deprivation also disrupts this natural pattern, not giving your cardiovascular system enough rest. Not sleeping enough can raise your heart rate and blood pressure after just a few bad nights of sleep.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/14975482/?ref=alphabetguides.com) Middle-aged adults who regularly sleep for less than six hours a night tend to have higher blood pressure than those who get eight hours, irrespective of their age, sex, whether they smoked, were physically active, or how much salt and alcohol they consume.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/16585410/?ref=alphabetguides.com) These changes are caused by sleep disrupting your 'autonomic nervous system',which regulates the plumbing of your cardiovascular system. When your [sleep is regularly disrupted](https://www.alphabetguides.com/sleep-and-health/), it activates your “fight or flight” response, which in turn increases the stress on your heart and blood vessels. When this accumulates over time, it damages the inner lining of your blood vessels, making them thicker and less flexible. This goes on to *increase* your blood pressure and stress on your heart (and accelerates the risk of getting cardiovascular disease). ## Sleep and your blood vessels ### Inflammation Just a few days of poor sleep triggers inflammation. Sleep, at its core, is really your body’s low-inflammation time. Disturbing your nervous system and hormonal balance when you sleep tips your body into a “pro-inflammatory" state.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/14975482/?ref=alphabetguides.com) Inflammation is strongly linked to cardiovascular disease. In fact, physicians use inflammatory blood markers to predict it. Even slightly elevated inflammation (called “low-grade inflammation”) will damage your blood vessels over time and increase your risk of heart attacks. ### Atherosclerosis Inflammation is one of the main causes of atherosclerosis. Having 'atherosclerotic' blood vessels is often considered the first stage of cardiovascular disease. This is basically the buildup of "plaque” inside your blood vessels (think of a blocked drain pipe). However, it may be years before more serious symptoms start to appear. Atherosclerosis is the main cause of heart attacks and strokes, which are two of the biggest killers out there. It doesn’t happen overnight; it develops over decades, but poor sleep accelerates it. Those who sleep under six hours a night and sleep poorly have a larger amount and more widespread atherosclerosis.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/30654884/?ref=alphabetguides.com) ## Sleep, weight gain and visceral fat Poor sleep promotes weight gain by stimulating your appetite and hunger hormones. These hormones tend to drive you to eat for reward (think sugary, salty, calorie-dense, carbohydrate-based [junk foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/)) rather than for your nutritional needs.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/15583226/?ref=alphabetguides.com) Researchers showed that those who get less than six hours a night ate about 559 more calories a day compared to when they slept normally. The location where you gain fat matters just as much as how much fat you gain. Poor sleep promotes the accumulation of 'visceral' fat, which is stored around your organs and is metabolically active (not in a good way).[\[6\]](https://pubmed.ncbi.nlm.nih.gov/20357041/?ref=alphabetguides.com) Irrespective of your [BMI or body weight](https://www.alphabetguides.com/beyond-the-scale/), high levels of visceral fat are linked to cardiovascular disease and risk factors like insulin resistance, high cholesterol and blood lipids, and inflammation. So it’s not just that poor sleep makes you gain weight (which it does), but it also promotes one of the worst types of fat, which damages your cardiovascular health. ## Poor sleep, cholesterol and blood lipids Researchers have reported links between poor sleep, high cholesterol (particularly the “bad” low-density lipoproteins), high blood lipids and cardiovascular health. However, the effects of poor sleep on your cholesterol and lipid levels aren’t as profound as they are on your blood pressure, inflammation and body weight.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/23027917/?ref=alphabetguides.com)[\[8\]](https://pubmed.ncbi.nlm.nih.gov/29247105/?ref=alphabetguides.com) The “good” high-density lipoproteins are important for cardiovascular health, as they clean up your blood vessels, carrying them back to the liver to be processed and made into something useful. Less than six hours of sleep a night is associated with lower amounts of “good” cholesterol and larger amounts of fats circulating in your bloodstream.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/31890656/?ref=alphabetguides.com) Lower “good” cholesterol, high “bad” cholesterol and high circulating fats are not signs of a healthy cardiovascular system; they are all independent risk factors for developing cardiovascular disease. --- ## Bottom Line _This post is for subscribers only._ ### How Poor Sleep Affects Your Brain and Mental Health URL: https://www.alphabetguides.com/sleep-and-your-brain/ Last updated: 2026-09-22T09:46:44.000Z summary - Consistently sleeping under 6 hours in your 50s and 60s is associated with an increased risk of developing dementia. - Having insomnia doubles the risk of developing depression, which can both be improved by getting better sleep. - Sleep is a time when the brain's "glymphatic system" clears metabolic waste products, including proteins that are linked to Alzheimer's disease. Sleep and brain health are inseparable — the quality and duration of your sleep directly influence your mood, cognitive abilities, and mental health. This article covers how and why poor sleep affects your brain health and mental health, from mood swings to dementia. As you’ve probably experienced yourself, a bad night's sleep makes you irritable and gives you brain fog. However, the long-term effects of consistent poor sleep (“sleep deprivation”) on your health run deeper than a bit of grumpiness. Sleep isn’t a leisurely choice; it is an active, biologically essential process where the brain repairs and restores itself and keeps it functioning healthily. If your sleep is regularly disrupted, it cannot do what is needed to keep it healthy. The consequences range from low concentration or mood right through to elevated risk of depression, anxiety, psychosis and dementia. ## How sleep repairs and restores the brain each night Sleep is organised into cycles of roughly 90 minutes. Each cycle contains lighter 'non-REM' sleep, deep 'slow-wave' non-REM sleep, and REM ('rapid eye movement') sleep. Each stage of the sleep cycle serves a different purpose in your brain. Deeper slow-wave sleep is when the brain 'consolidates' your memories (storing things that happened and things you learnt that day). It also clears metabolic waste (via the 'glymphatic system') and releases hormones to orchestrate the repair and restoration processes in your body (including your brain). REM sleep is when emotions are processed, creative associations between ideas are formed, and the brain essentially 'stress-tests' or 'rehearses' made-up emotional experiences, which are also known as dreaming (or nightmares). Your brain is very active during this stage of sleep. Disrupting any sleep stage has consequences for the brain functions that they support.[\[1\]](https://www.ncbi.nlm.nih.gov/books/NBK526132/?ref=alphabetguides.com) ## Sleep deprivation and mood: why you feel irritable Even one night of bad sleep can affect your mood and emotions the next day (as you all probably know already). Don’t worry, it’s not just you; poor sleep makes you more “emotionally reactive” and less able to regulate reactions to adverse life events.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/17956744/?ref=alphabetguides.com) The same region of the brain that temporarily affects your mood and emotions is also linked to anxiety, PTSD and depression. So poor sleep seems to *temporarily* recreate the similar mood and emotional conditions that are reported with these more serious mental health disorders. Bad mood, irritability, short temper, and frustration are some of the most consistently reported consequences of sleep deprivation. However, the good news is that they are also the first to be resolved when you return to sleeping well. ## Poor sleep and depression: a two-way relationship Poor sleep and insomnia are reported alongside depression and appear to double your chances of developing it. Unrelenting poor sleep wrecks the way your brain normally functions. It seems to particularly affect the role that the 'neurotransmitters' in your brain play in controlling your mood, motivation and reward system (your 'serotonin' and 'dopamine' systems).[\[3\]](https://pubmed.ncbi.nlm.nih.gov/21300408/?ref=alphabetguides.com) Poor sleep also increases inflammation in your brain, which is associated with depression. It also messes up the sleep stages where you process your emotions (including processing the bad ones properly). Unfortunately, [depression](https://www.alphabetguides.com/exercise-for-depression/) can also disrupt sleep, worsening depression itself. This creates a reinforcing cycle that is difficult to break without addressing both your sleep issues and depression at the same time. But good news: there are treatments available that treat both at the same time.[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6487874/?ref=alphabetguides.com) ## Poor sleep and anxiety: why they reinforce each other It has been shown that poor sleep affects the trigger for your fight-or-flight response, which resembles anxious or 'nervous' behaviour and thoughts. At the same time, anxiety is one of the most common causes of poor sleep and insomnia. Racing thoughts, racing heart rate, arousal and difficulty “switching off” are common amongst those with anxiety and insomnia.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/23804084/?ref=alphabetguides.com) Elevated stress hormones like [cortisol](https://www.alphabetguides.com/what-is-cortisol/) and noradrenaline are associated with anxiety and poor sleep. These hormones work against your natural sleep-inducing processes in your body. Unsurprisingly, it is not uncommon for anxiety, depression and insomnia to occur together at the same time (bad news there!). However, the good news is that this also means they have similar overlapping treatments, meaning you can treat all three issues at the same time. This reflects how close these three disorders are to one another. ## Poor sleep and ADHD: a bidirectional relationship Sleep issues are common in people with ADHD. So researchers have questions about whether ADHD symptoms are caused by, or mistaken for, sleep deprivation. There is definitely overlap: poor attention, impulsive behaviour, being overly emotional, and hyperactivity are all commonly reported in both ADHD and people who are sleep-deprived. Researchers reported that improving sleep in children with ADHD and sleep disorders also improved their ADHD symptoms. Both ADHD and people with sleep deprivation have reduced activity in the same areas of the brain, which are associated with memory, completing tasks successfully and efficiently, and controlling impulses. Many people with ADHD also report being night owls and having sleep disorders, making normal work schedules challenging.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/21808754/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/39354860/?ref=alphabetguides.com) ## Sleep deprivation, psychosis and hallucinations Most people think that only extreme sleep deprivation can cause hallucinations, but it can actually occur sooner than most people expect. Hallucinations begin after as little as 24 to 48 hours without sleep. After 72 hours of no sleep, things start getting really serious, with paranoia, delusions and very complex hallucinations occurring. Research shows that poor sleep is associated with “psychotic experiences” (hallucinations or delusions) in otherwise healthy people. Likewise, improving sleep in people with psychosis can reduce their symptoms.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/26407540/?ref=alphabetguides.com) The cause is pretty well established as being a faulty 'dopamine system' (the same system involved in schizophrenia and other psychotic disorders). Insomnia is common in people with schizophrenia and bipolar disorder, and episodes of poor sleep or sleep disruption tend to worsen the condition. ## How poor sleep destroys your memory, learning, academic, and cognitive performance During both REM and non-REM sleep, your brain’s short-term memory store replays and transfers new information (usually from that day) to your long-term store to use later on. Researchers found that people who slept after learning a new task had significantly better task performance 12 hours later, compared to people who stayed awake.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/11100141/?ref=alphabetguides.com) Sleep quality before learning matters too, as it “refreshes” your brain’s storage space and improves your ability to learn new information. In addition to memory, poor sleep also affects other mental processes, like your working memory, processing speed, attention, reaction time, decision-making, decision making and creative problem solving. As a result, it should come as no surprise that students who consistently get enough sleep and who have rigid [sleep schedules](https://www.alphabetguides.com/fix-your-sleep-schedule/) generally get better grades. In some cases, sleep is a better predictor of grades than the amount of time spent studying.[\[10\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3959895/?ref=alphabetguides.com) So, cramming through the night, pulling an all-nighter before an exam, is one of the most counterproductive things you can do. The information you’ve reviewed during the night is unlikely to be “consolidated” without any subsequent sleep. So, your performance the following day will be compromised even before the exam has started. ## Poor sleep and dementia: what the evidence shows The waste products your brain produces during the day are cleared out by the 'glymphatic system' while you’re sleeping. One of the waste products that’s built up, 'amyloid', is linked to Alzheimer’s disease.[\[11\]](https://pubmed.ncbi.nlm.nih.gov/38501315/?ref=alphabetguides.com) Research has shown that consistently sleeping less than 6 hours a night in your 50s and 60s is associated with a 30% increased risk of having dementia, regardless of your other lifestyle choices.[\[12\]](https://pubmed.ncbi.nlm.nih.gov/33879784/?ref=alphabetguides.com) Researchers think this may be due to impaired glymphatic system function, which damages or kills off your brain cells. Just like many other brain and mental disorders, dementia and Alzheimer’s also disrupt areas of your brain that regulate your sleep, creating a vicious cycle — and worsening disease progression. [Improving your sleep](https://www.alphabetguides.com/how-to-sleep-better/) in midlife may be one of the most underused strategies for preventing dementia. ## How sleep affects stress and your mental resilience Consistent bouts of poor sleep trigger your body’s 'stress-response' system, increasing your cortisol levels. Keeping your cortisol high for a long period of time can reduce your brain volume and impair its function (particularly memory and emotions).[\[13\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6260201/?ref=alphabetguides.com) This also means that your brain is more sensitive to stress and is also less well equipped to handle it (due to its impaired function). This is commonly expressed as feeling “overwhelmed” when under stress or put into stressful situations. Poor sleep just makes the situation worse. Improving your sleep and [keeping your cortisol levels down](https://www.alphabetguides.com/ways-to-decrease-cortisol/) is one of the best things you can do for your brain. #### How poor sleep destroys your brain health and mental health - Lowers your mood by disrupting your emotional control processes. - Increases the risk of depression by blunting your reward pathways. - Increases risk of ADHD by impairing normal brain function. - Increases anxiety by (over)-activating your threat response. - Lowers your cognition by impairing the development of neural connections. - Increases risk of dementia by impairing your glymphatic system function. - Increases risk of psychosis by impairing normal dopamine function. - Increases stress and increases cortisol - Decreases your psychological resilience by increasing your stress response. --- ## Frequently Asked Questions _This post is for subscribers only._ ### Beauty Sleep: How Good Sleep Makes You More Attractive URL: https://www.alphabetguides.com/beauty-sleep/ Last updated: 2026-09-22T09:46:19.000Z summary - Sleep-deprived people are consistently rated as less attractive — other people can detect poor sleep in facial appearance without being told. - Growth hormone released while you sleep drives collagen synthesis, so poor sleep causes wrinkles, uneven skin tone, and reduced elasticity. - Poor sleep increases cortisol, increasing skin oil production. This worsens acne and impairs the immune response that clears it. 'Beauty sleep' is the idea that adequate, [quality sleep](https://www.alphabetguides.com/how-to-sleep-better/) improves your physical appearance — *it is* backed by scientific evidence. This article explores eight ways sleep affects various aspects of appearance, including face, hair, body weight, and beyond. Most people know that a bad night's sleep leaves them looking rough the next day. But the consequences of persistent poor sleep go much deeper. Sleep is the time when your body carries out many of its repair and regeneration processes that are fundamental to how you look and age. If you disrupt these processes, it will accelerate the ageing process and will show on your face. ## "Beauty sleep": The Evidence The phrase may sound like a marketing term, but researchers have tested it directly. Researchers did a study where they got a group of people to rate photos of another group of people in a sleep-deprived state, and then rate them again after a good night's sleep. The people rating the photos didn’t know whether the people were sleep-deprived or not. Yet, they consistently rated them as less attractive when sleep-deprived. So it’s true, you do “look tired” when you sleep poorly, and people *can* see it (even if they are too polite to say so).[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3738045/?ref=alphabetguides.com) --- ## How Does Sleep Affect Your Skin? ### Wrinkles During deep sleep, your body releases 'growth hormone', which in turn stimulates 'collagen synthesis'. Collagen is a vital protein in your body that keeps your skin firm, smooth, and elastic. Poor sleep means less growth hormone, which means less collagen, which means your skin’s youthful appearance (its “scaffolding”) will break down faster. Poor sleepers tend to have more fine lines, uneven pigmentation and lower skin elasticity. Your skin also doesn’t recover and repair itself as quickly when it is damaged (say from sunlight exposure) — this is arguably more important and what causes early ageing.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/25266053/?ref=alphabetguides.com) The skin renewal process peaks at night, when the body takes time to repair or replace damaged skin cells. So regularly cutting your sleep time short will affect the way your skin looks. Getting enough high-quality sleep each night is probably one of the most important things you can do for your skin. Sleeping on your back will also reduce compression on the skin of your face, which may help delay the onset of sleep lines and wrinkles later in life. ### Skin hydration Your skin’s outermost barrier (the “stratum corneum”) is really important. It protects the deeper layers of your skin from the outside world and keeps them hydrated. It keeps the bad stuff out and the good stuff in. However, sleep deprivation causes you to lose moisture from your skin, leaving it dry, sensitive and irritated.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/25266053/?ref=alphabetguides.com) It also makes it more sensitive to 'irritants' (from the environment) and more prone to skin conditions like eczema and rosacea flares. This is why a night-time moisturiser is usually more important than the daytime one, as your skin’s pores are more open and the repair process is more active at night, while you sleep. However, no amount of overpriced moisturiser will make up for a [poor sleep schedule](https://www.alphabetguides.com/fix-your-sleep-schedule/). ### Acne and skin breakouts As we mentioned in the previous section, poor sleep elevates cortisol — the body’s “stress hormone”, which will get multiple shout-outs in this article. In addition to doing many other things, cortisol stimulates your skin to produce extra skin oil (“sebum”). This creates favourable conditions for acne to thrive, or worsen if you already have it. Sleep deprivation also impairs your immune system function, which takes care of the skin’s protective barrier. This means that it delays the clearing-up process after a breakout of acne.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/15679586/?ref=alphabetguides.com)[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC12615111/?ref=alphabetguides.com) Put simply, poor sleep increases your chances of getting acne, makes it worse if you have it already, and also makes you have it for longer. More bad news: having acne itself can also affect your sleep and increase your stress levels. So poor sleep causes acne, and acne causes poor sleep. It’s a vicious circle or a doom loop. Read about how to lower your cortisol levels and keep your pillowcases clean. Excess skin oil and bacteria produced by your skin can find their way onto your pillow overnight. [6 Ways to Decrease CortisolStubbornly high cortisol doesn’t have to be permanent. There are several proven, easy ways to bring your cortisol back under control.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-24035f66-776f-4680-96c9-2692bec92298.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1489710437720-ebb67ec84dd2-4f28ac14-48ba-4fbc-af8f-ceebcfb4a982.jpeg)](https://www.alphabetguides.com/ways-to-decrease-cortisol/) --- ## Does Poor Sleep Cause Eye Bags? This is probably the most immediate and obvious thing you notice after a poor night's sleep. Poor sleep raises your [cortisol levels](https://www.alphabetguides.com/what-is-cortisol/), which then causes fluid to pool in the loose, delicate connective tissues around your eyes — this is the classic "puffy" eye look. Secondly, poor sleep also causes the blood vessels just below your eyes to dilate and become more visible. Because the skin is very thin under your eyes, this creates those dreaded dark circles. In addition to dark circles, people also notice hanging eyelids, red eyes and swelling under the eyes as facial markers of poor sleep.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3738045/?ref=alphabetguides.com) More bad news comes from the fact that, over time, poor sleep also reduces the thickness of the skin under the eye, making the dark circles look worse and potentially permanent. There’s also a very strong genetic component to those dark circles, so even if your sleep is perfect, be aware that it may not get rid of them entirely. ## Does Sleep Cause Hair Loss? Your hair is consistently going through growing and shedding cycles throughout the day and night. Poor sleep and high cortisol (again!) can prematurely cause the hair to shed. Hair loss from poor sleep and high stress is caused by the same reason: stubbornly high cortisol levels. A second important hormone, 'melatonin', is also linked to sleep and hair health. Melatonin is produced when it's dark (normally just before bed) and is suppressed when there's light. However, your hair also appears to respond to melatonin. When melatonin is applied directly to the skin on your head (“topical application”), it helps hair growth in both men and women, particularly those of us with hair loss issues (e.g., “androgenic alopecia”).[\[5\]](https://pubmed.ncbi.nlm.nih.gov/36877877/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/14996107/?ref=alphabetguides.com) Since your body’s natural production of melatonin depends on adequate sleep in darkness, poor sleep disrupts one of your hair growth signals. We have an article on how to fix your sleep schedule and restore your body's melatonin production. [How to Fix Your Sleep Schedule: A 7-Step PlanBad sleep leaves you exhausted, foggy, and stuck in a frustrating cycle. This step-by-step plan helps reset your body clock.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-4010bc33-1ef6-4fc1-a339-983dbb700280.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1586294310477-243d2beb0be1-84cfe655-f76b-4e20-a502-9e05d133b952)](https://www.alphabetguides.com/fix-your-sleep-schedule/) --- ## How Sleep Affects Your Facial Appearance ### Puffiness Persistently high cortisol (yet again!), caused by poor sleep, increases another hormone in your body (“aldosterone”). This leads to higher fluid retention and a “puffy face” around the eyes, cheeks and jawline. This is different (but can occur alongside) the puffiness “under the eyes”. High salt and alcohol intake can make the problem worse, as each of these independently promotes fluid retention, exacerbating the puffiness. So, that salty junk food after a boozy night out and a poor night's sleep really is a beauty killer. You can offset some of the puffiness by (maybe confusingly) ensuring you drink enough water — yes, drinking more water can actually *reduce*excess fluid retention! ### Weight gain Another overlooked benefit of getting your beauty sleep is its role in preventing weight gain. Sleep deprivation disrupts two [appetite hormones](https://www.alphabetguides.com/appetite-and-body-weight/): one which makes you hungry ('ghrelin') and another that tells you you’re full ('leptin'). Research shows that people who sleep less are more likely to gain weight and be obese.[\[7\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC2723045/?ref=alphabetguides.com) If you start gaining fat, it tends to accumulate around the face, neck and jaw and visibly affect your facial (and overall) attractiveness. There are loads of other health implications to being overweight (outside of beauty), so we have written articles on “[How to Sleep Better](https://www.alphabetguides.com/how-to-sleep-better/)” and how to lose fat and maintain a healthy bodyweight.

Shakshuka This egg dish is a staple in North Africa. It is a one-pan meal that is easy and packed with flavour. Prepare the tomato sauce ahead of time, and keep a batch stored in your fridge (up to 5 days) to simply reheat and crack your eggs into it. The mix of North African spices, peppers, and tomatoes adds instant depth of flavour with minimal effort. If you want a higher-protein, healthier and heartier version, add some crumbled feta, a spoonful of Greek yoghurt, chickpeas or cooked chicken, or add some [leafy greens](https://www.alphabetguides.com/superfood-leafy-greens/) just before adding the eggs. Serve with crusty whole-grain bread or toast to dip into the egg yolks and tomato sauce. ![Stainless steel bowl of Shakshuka.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1582492710145-d723e0a219f8.jpeg) ### Ingredients (serves 2) - 2 tbsp [extra-virgin olive oil](https://www.alphabetguides.com/superfood-olive-oil/) - 1 small diced onion - 1 diced red pepper - 3 minced garlic cloves - 1 tsp ground cumin - 1 tsp paprika - ¼ tsp cayenne pepper - 1 can of diced tomatoes - 4 large eggs - Fresh parsley or coriander for garnish. ### Directions 1. Heat the extra-virgin olive oil in a large pan over medium heat, then add the onion and bell pepper, cooking for about 5 minutes until softened and sweet. 2. Stir in the garlic and spices and cook for another minute. 3. Pour in the diced tomatoes with their juices, season with salt and pepper, and let the mixture simmer for about 10 minutes until it thickens slightly and the flavours meld together. 4. Using the back of a spoon, create four small wells in the sauce, then carefully crack an egg into each well. 5. Cover the pan and cook for 5 minutes, or until the egg whites are set but the yolks are still runny (or as you prefer your eggs cooked). 6. Remove from heat, garnish with fresh herbs, and serve immediately with warm bread for dipping. --- ## #2\. Greek yoghurt, honey, walnuts and fresh figs A simple breakfast that lets the high-quality ingredients speak for themselves. Greek yoghurt provides protein and fat that keep hunger at bay. The figs and honey provide natural sweetness in place of refined, added sugars. You can use dried figs when fresh ones aren’t available; rehydrate them in warm water for at least 10 minutes before cooking. You can also use pomegranate, red berries, stone fruit like peaches and apricots instead of figs. You can toast the walnuts in a dry pan (2-3 minutes) to intensify their flavour and texture. If you don’t want to add sugar from the honey, try drizzling with tahini instead, with a pinch of cinnamon. ### Ingredients (serves 2) - 1 cup full-fat Greek yoghurt - 3-4 fresh figs (quartered) - 2 tbsp chopped walnuts - 1-2 tbsp honey - Optional garnishes include a pinch of cinnamon, fresh mint leaves, and orange or lemon zest for [added colour](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/) and flavour. ### Directions 1. Spoon the yoghurt into your serving bowl. 2. Add the figs on top, along with the walnuts, then drizzle the honey over everything (with any other extras), allowing the honey to pool in places for flavour contrast. 3. Serve and eat immediately (or as soon as possible). --- ## #3\. Whole-grain toast with avocado and tomato Classic avocado toast with the addition of fresh tomatoes and peppery extra-virgin olive oil — fresh, simple, and delicious. Using good bread makes or breaks the dish, so use a thick-cut whole-grain sourdough or country loaf. If you want to increase protein content, add an extra-virgin olive oil fried egg, crumbled feta, or beans (mashed with garlic and lemon). The healthy fats from the avocado and extra-virgin olive oil help you absorb the fat-soluble vitamins and nutrients in the tomatoes.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/11084294/?ref=alphabetguides.com) ![Sliced tomato, fried egg and avocado on toast on a white ceramic plate.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1623691752472-a6d33855e5de.jpeg) ### Ingredients (serves 2) - 2 slices of thick-cut whole-grain or sourdough bread - 1 ripe avocado (halved and pitted) - 1 medium ripe tomato (sliced) - 2 tbsp extra-virgin olive oil - Optional: fresh basil or coriander leaves, microgreens, red chilli flakes, hemp seeds, or a squeeze of lemon juice. ### Directions 1. Toast the bread slices until golden and crispy. 2. While the bread toasts, scoop the avocado flesh into a small bowl and mash it roughly with a fork, leaving some chunks for texture rather than making it completely smooth. 3. Season the mashed avocado with a pinch of salt and pepper, then spread it generously over each slice of warm toast. 4. Layer the tomato slices over the avocado, and season with another pinch of sea salt and drizzle with extra-virgin olive oil. 5. Eat immediately while the toast is still warm and crispy. --- ## #4\. Frittata with spinach, tomatoes and feta Unlike omelettes that require some cooking skills, frittatas are a bit more forgiving; simply whisk the eggs with your filling, put it into a pan, and then into the oven. Frittatas can be stored and eaten later in the week, warmed or at room temperature. Serve with a salad and whole-grain bread to turn this breakfast dish into a light lunch. The eggs, spinach, tomatoes and feta in this recipe create a high-protein, nutritionally balanced breakfast. You can use different [vegetable combinations](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/) like cooked courgettes, peppers, mushrooms, asparagus or artichokes. You’ll need a cast-iron or oven-proof pan. ### Ingredients (serves 2) _This post is for subscribers only._ ### 6 Ways to Decrease Cortisol URL: https://www.alphabetguides.com/ways-to-decrease-cortisol/ Last updated: 2026-09-22T09:47:03.000Z summary - Regular exercise lowers cortisol, despite spiking it acutely. Overtraining and poor recovery do the opposite and keep cortisol levels high. - Mindfulness techniques need as little as 8–10 minutes a day to begin reducing cortisol. - Laughing reduced cortisol. "Forest bathing" also produces measurable reductions in as little as 15 minutes. Cortisol isn't your enemy. It wakes you up in the morning, fuels your workouts, and helps your body respond to threats. The problem isn't cortisol itself — it's when your cortisol system never switches off. When your levels stay stubbornly high, that's when the problems happen: weight gain around your midsection, [disrupted sleep](https://www.alphabetguides.com/sleep-and-health/), anxiety, illness, low libido, and fatigue. Here are some things that you can do to fix it. --- ## #1\. Exercise [Exercise](https://www.alphabetguides.com/tag/exercise/) is one of the best things you can do to help control your cortisol, but the relationship isn’t straightforward. In the short-term, exercise *increases* cortisol. Whether it's a run, a weights session or a spin class, it will spike your cortisol. That’s bad, right? Well no! It’s a normal, expected, perfectly natural response. What cortisol is doing is helping your body release energy from its stores to fuel the exercise you're doing. This is exactly what you want to happen. Regular exercise *lowers* cortisol. So your cortisol response while you're exercising is completely different to what happens to your cortisol levels after you finish (and recover) from exercise. Remember, even if you follow exercise guidelines, you’ll only ever spend 1-2% of your waking hours exercising. The remaining 98% of your time, when you’re not exercising, is really more important. People who regularly exercise tend to have lower cortisol levels and healthier, better-functioning cortisol systems.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/35777076/?ref=alphabetguides.com) ### Both running and walking lower cortisol levels The type of exercise seems to matter less than consistency. Walking in nature seems particularly effective, as the environment you are in also affects your cortisol and stress levels.[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6920124/?ref=alphabetguides.com) A slow, leisurely [walk](https://www.alphabetguides.com/why-walking-beats-running/) will also not spike your cortisol whatsoever, whereas running will. So if you want to exercise without increasing your cortisol, walking beats running.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/18787373/?ref=alphabetguides.com) Aim for moderate-intensity aerobic exercise like running, brisk walking, cycling and swimming, 2-4 times a week to start with. Avoid the trap of training more and more as you get fitter. Too much high-volume, high-intensity exercise, without adequate rest and recovery, can increase your cortisol levels and keep them high. This is referred to as “overtraining”. More exercise isn’t always better. [ExerciseEvidence-based exercise guides on strength, endurance and conditioning — practical programs and principles to build fitness safely.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-db396495-04df-4ac7-9569-0e0cc484df79.png)Alphabet Guides![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1776977519844-634b564d4a9a-d4f1942e-0caf-47cb-b75f-f6da53e70a55.jpeg)](https://www.alphabetguides.com/tag/exercise/) --- ## #2\. Mindfulness and Meditation “Mindfulness” interventions work for lowering cortisol. It seems to lower cortisol for people who are stressed (with high cortisol) and have normal cortisol levels (keeping them low). Although both are effective, mindfulness and meditation were more effective than “mind-body therapies” and “talking therapies”.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/37879237/?ref=alphabetguides.com) Researchers suggest that it’s not all about how much mindfulness you do. Like exercise, more isn’t always better. So 8–10 minutes of daily mindfulness is enough to start lowering your cortisol. The specific “type” of mindfulness appears to matter less than doing it consistently — app-based programmes, breathwork, formal “MBSR” programmes, and different meditation programmes have all been shown to work. So does just relaxing as well! --- ## #3\. Laughter Laughter is one of the most underrated tools for decreasing your cortisol. The more you laugh, the lower your cortisol seems to go. Researchers showed that those who went out of their way to make sure they laughed more reduced their cortisol levels by a third. It seems to work by taking your mind out of its “fight-or-flight” threat-response mode.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/37220157/?ref=alphabetguides.com) Being in a positive emotional state keeps your cortisol low; laughing just seems to help you on your way there. It may sound almost too simple, but the evidence is there. Genuine laughter, from friends and family, comedy, or anything that makes you genuinely happy and amused, will lower your cortisol. It is also pretty much free, has no side effects, and is arguably underused. It turns out laughter is (one of) the best medicines. --- ## #4\. Mind-Body Practices Yoga and other similar “mind-body” practices like Tai-chi, Pilates, or Qigong use exercise, breathing and mindfulness together. All of these independently lower cortisol, so it's no surprise that combining the three of them reliably lowers your cortisol as well. In addition to the physical health benefits of exercise, yoga has been shown to reduce cortisol levels throughout the day. It also reduces your cortisol response to stress, meaning it brings down cortisol more quickly after it has spiked. One of the hallmarks of high stress is not only high cortisol levels, but also the inability to bring them down quickly once they’ve spiked.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/28963884/?ref=alphabetguides.com) For lowering cortisol, gentle or restorative yoga appears to be as effective as more intense styles — and potentially more so, since high-intensity exercise can spike cortisol in the short term. Even a brief yoga session (20–30 mins) may meaningfully speed up cortisol recovery if you’re feeling stressed. Regular practice can help lower your baseline cortisol levels over time. --- ## #5\. “Bathing” “Bathing” doesn’t always mean water; it includes special therapeutic variations, such as forest bathing, hot spring bathing, foot bathing, spa bathing, mud baths, steam baths, sauna baths and hydrotherapy pools. They've all been shown to lower stress and cortisol levels. The Japanese practice of “shinrin-yoku”, meaning 'forest bathing', seems particularly effective. Exposure to the fresh air and cool temperatures, forest scents from the plants and animals, the repeating visuals from the trees, and the quiet, echoing, low-frequency sounds are thought to work together to lower your cortisol.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/31001682/?ref=alphabetguides.com) These therapies are “immersive” and “multisensory”, meaning they occupy your senses. This allows your mind to drift and relax, lowering your fight-or-flight threat-response and thus your cortisol. So what can you do at home? A warm bath or shower before bed has been shown to [improve sleep](https://www.alphabetguides.com/how-to-sleep-better/), which in turn may help lower cortisol and stress. Researchers have suggested you can recreate a forest environment in your bathroom: use forest sounds and scents, natural light, bathroom plants, then just lie back and visualise a forest in your mind. Easier yet, just get out in nature, into a forest. Combine it with light physical activity, such as walking or yoga; as little as 15 minutes of forest bathing is shown to reduce cortisol levels. --- ## #6\. Diet and Supplements _This post is for subscribers only._ ### What Foods & Supplements Lower Cortisol URL: https://www.alphabetguides.com/eat-to-lower-cortisol/ Last updated: 2026-09-14T09:46:30.000Z summary - A Mediterranean-style diet reduces cortisol more effectively than most diets, due to its high content of magnesium, omega-3s, and polyphenols. - Low-carbohydrate diets and fasting increase cortisol. Whereas eating whole-food carbohydrates reduces cortisol. - Ashwagandha is the only supplement with consistent evidence for lowering cortisol; caffeine and alcohol both increase it. Your diet *can’t*completely limit all the stress in your life. But it can change how your body responds to it. Cortisol, a glucocorticoid hormone released from your adrenal glands in response to stress, is sensitive to the nutritional environment you create in your body, so it can be influenced by your diet. Some of the things you eat exacerbate cortisol's release and its effects. But eating the right things can lower and help control your cortisol response and reduce its negative effects on your body. ## Can or should you actually reduce your cortisol? Yes, but you don’t want to eliminate cortisol. You need cortisol to wake up, to exercise, to fight infections and to respond to threats in your environment — read our article “[What Is Cortisol: Hero or Villain?](https://www.alphabetguides.com/what-is-cortisol/)” for more info. What you want is for cortisol to follow its natural rhythm: - High in the morning - Declining throughout the day - Low at night - Spikes in response to genuine stress - Return to baseline quickly after spiking Diet and supplement changes are most effective at reducing cortisol when levels are already mild to moderately high, typically due to stress, poor sleep, [overtraining](https://www.alphabetguides.com/overtraining-how-to-diagnose-prevent-it/), poor general health, or an unhealthy lifestyle. They aren’t going to fix high cortisol if you have specific or serious medical conditions causing it — that’ll require specialist healthcare. But bringing persistently high cortisol levels back to normal should have measurable benefits like improving your sleep, body composition, physical health and mental health. The goal is not to eliminate cortisol or suppress its normal, healthy short-term response to stress; rather, it is to bring your cortisol levels back under control. ## How do you know if you have high cortisol? Confirming you definitely have high cortisol means testing — this means a blood, urine or hair follicle sample and an expensive test. However, several symptoms suggest your cortisol is running too high: 1. Fatigue that doesn’t improve with rest (“tired but wired”) 2. Difficulty falling asleep, staying asleep or waking up early 3. Increased appetite for junk foods, weight gain around the abdomen 4. Slow recovery from exercise, getting ill often, low libido, anxiety and irritability. If you recognise several of these, it's worth discussing them with your doctor before making any significant lifestyle changes. ## Foods that lower cortisol ### Carbohydrates When your blood sugar levels drop, your body will release cortisol (and some other hormones) to bring them back up. So, to avoid spiking your cortisol throughout the day, you need to avoid the large swings in your blood sugar levels when you eat. Do this by eating enough protein and fat at each meal, choosing fibre-rich, low-glycaemic carbohydrates, and [avoiding ultra-processed foods](https://www.alphabetguides.com/how-to-avoid-upfs/). Increasing your carbohydrate intake (particularly when under stress) within a healthy, whole-food diet actually reduces cortisol, your stress levels and recovery from stress after being exposed to it.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/31652899/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/27716864/?ref=alphabetguides.com) So, eating carbohydrate-rich whole foods like fruits, vegetables, legumes and wholegrains can be used to control your cortisol — especially for people who’re training hard or under quite a bit of stress already. Yes, this means that low-carbohydrate diets tend to increase your cortisol levels. But the good news is that the increase in cortisol levels only lasts for about 3 weeks into the diet, and tends to return to normal after that — the cortisol increase doesn’t seem to be permanent.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/35254136/?ref=alphabetguides.com) You may also want to avoid (or minimise) exposing yourself to any extra stress if you’re planning on significantly reducing your carbohydrate intake. ### Fasting and calorie restriction This also means that fasting and calorie-restriction diets increase cortisol levels. But again, over time, your cortisol levels will drift back to normal levels as your body adapts to being exposed to repeated fasts or [low-calorie diets](https://www.alphabetguides.com/fasting-mimicking-diet/).[\[4\]](https://pubmed.ncbi.nlm.nih.gov/26586092/?ref=alphabetguides.com) So, despite the positive effects on your body weight and health, fasting doesn’t lower your cortisol. In fact, skipping meals or one-off fasts will actually increase your cortisol by tanking your blood sugar levels. ### Mediterranean diet One diet that does lower your cortisol levels is the Mediterranean diet. It actually beats following standard dietary guidelines for lowering cortisol (as well as having many other health benefits).[\[5\]](https://pubmed.ncbi.nlm.nih.gov/38034010/?ref=alphabetguides.com) This makes sense because the Mediterranean diet is naturally rich in several cortisol-lowering nutrients like magnesium, omega-3s, plant polyphenols and vitamin C. ## What supplements lower cortisol? _This post is for subscribers only._ ### Volumetrics Diet: A Review URL: https://www.alphabetguides.com/volumetrics-diet/ Last updated: 2026-09-14T14:06:04.000Z summary - The volumetrics diet is based on eating foods that are "low-energy density": more food for fewer calories. - The diet is safe and effective at managing hunger, helping with sustainable weight loss, which requires less willpower. - Increased intake of low-energy-dense foods (e.g., fruits and vegetables) will improve health outcomes, but may not be suitable for everyone. Unlike most popular diets, the “volumetrics” diet (or “low-energy-density” diet) does not ban food groups or set rigid macronutrient or calorie targets. Instead, it is built around a single basic principle: eat more food for fewer calories. The key concept behind it is “energy density”, which is the number of calories per gram of food. You’ll probably see it reported on food labels and on nutrition databases as kcal per 100g. Very low “energy-dense” foods are typically defined as having less than 150 calories per 100 grams of food.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/19303887/?ref=alphabetguides.com) Watery foods like fruits, [vegetables](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/), soups, and stews have very low energy density, meaning you can eat a large volume of them without consuming many calories. Dry, processed, or high-fat foods have high energy density (i.e., a small amount of food delivers a lot of calories). By eating a lot of low-energy-density foods, the volumetric diet is based on the theory that this allows you to eat larger, more satisfying portions that make you feel “full”. This means you can eat fewer calories but without the restrictions and hunger that accompany other diets. To follow the diet, foods are grouped into four categories by energy density: very low (fruits, vegetables, broths), low (whole grains, lean protein, legumes), medium (meats, cheese, some breads), and high (nuts, oils, sweets, crisps). The diet doesn't prohibit higher-density foods but encourages you to base meals around the first two categories and eat the others in moderation. --- ## Example foods and dishes - **Breakfast:** - Porridge with skimmed milk, sliced strawberries, and blueberries - Mixed vegetable omelette with whole-grain toast - **Lunch:** - Big mixed salad with grilled chicken, cucumber, tomatoes, and a light vinaigrette - Chunky vegetable and lentil soup with a wholemeal roll - **Snack:** Sliced apple, celery sticks, and a small pot of hummus - **Dinner:** - Baked cod with roast Mediterranean vegetables and brown rice - Turkey mince stir-fry with broccoli, pak choi, peppers, and noodles - **Dessert:** Lime-marinated watermelon and berry fruit salad - **Drinks:** Water, sparkling water with lemon, herbal tea, black coffee --- ## Pros The volumetrics diet's main edge over other diets is its approach to hunger, or at least the recognition of it; rather than delegating it to willpower. Most calorie-restricted diets work by asking people to eat less. Whereas volumetrics works by helping people eat more of the right things. Research shows that adding water-rich fruits and vegetables to a reduced-fat diet (thus reducing its energy density) produced greater [weight loss, fat loss](https://www.alphabetguides.com/tag/fat-loss/), *and* less hunger compared to a [low-fat diet](https://www.alphabetguides.com/low-fat-diet/) alone. This is a meaningful finding: too much hunger is the main reason most diets fail.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/17556681/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/6303104/?ref=alphabetguides.com) From a nutritional standpoint, the diet is great, naturally steering people towards eating plants, whole grains and [lean protein](https://www.alphabetguides.com/high-protein-diet/) sources. No specific food groups are prohibited; the diet has a balanced macronutrient profile, and the high-fibre and water content of the diet is good for digestive health. The diet is also flexible, affordable, and pretty practical: building meals and snacks around vegetables and whole grains doesn’t require any specialist or expensive ingredients, equipment or subscriptions. ## Cons The primary limitation of the diet is the breadth and depth of its evidence base compared to some other (better researched) diets (e.g., [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/)). While the underlying theory, that energy density controls satiety and body weight, is well-supported, the body of evidence specifically testing the diet is relatively small.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/33393504/?ref=alphabetguides.com) That said, there is strong evidence showing that adding low-energy-dense foods (e.g., fruit and vegetables) to your diet is beneficial for weight loss and general health.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/17490955/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/35459185/?ref=alphabetguides.com) If you’re fully adopting the diet, you’ll have to change how you create your meals. Energy-dense foods need to be replaced with high-volume watery substitutes. So, some cooking skills, meal planning and budgeting are required. People who have little time and cooking skills may find it more difficult than simpler, rule-based diets (e.g., [intermittent fasting](https://www.alphabetguides.com/intermittent-fasting-diet/)).[\[7\]](https://pubmed.ncbi.nlm.nih.gov/40533752/?ref=alphabetguides.com) Finally, like all dietary approaches, results depend on consistent application. The diet does not enforce strict calorie limits, which gives it flexibility but also means it is easy to miscalculate the energy content of moderate- and high-density foods eaten alongside less dense options. --- ## Bottom Line Volumetrics is one of the most logical, scientific and practical dietary approaches around. Its focus on managing hunger rather than restrictions and willpower sets it apart from most other weight-loss diets, and its nutritional profile is generally better. Rather than an “all-in” volumetrics approach to dieting, we believe that simply factoring in “energy-density” when choosing what to eat will yield good results for (relatively) little effort. The full diet won't suit everyone as it requires a meaningful increase in fruit and vegetable intake and some willingness to cook. But for people looking for a sustainable, evidence-based approach to weight loss or maintaining a healthy body weight, which does not demand deprivation, it is a strong choice. --- ## Overall Score: **★★★★☆** - Health Benefits: **★★★★☆** - Nutrition: **★★★★☆** - Weight Control: **★★★★★** - Ease to Follow: **★★★★☆** - Safety Profile: **★★★★★** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

The juice diet, also known as a juice cleanse or juice fast, means consuming mainly (or exclusively) fruit and vegetable juices. Juice diets typically range from just a day to weeks at a time. During the diet, solid foods are replaced with freshly extracted juices or pre-prepared store-bought ones. They are often marketed as a way to ‘detoxify’ the body, promote quick [weight loss](https://www.alphabetguides.com/tag/fat-loss/), or ‘reset’ your eating habits. The diet is based on providing concentrated sources of micronutrients, antioxidants, and other nutrients, while giving the digestive system a ‘rest’ from processing solid foods. Proponents of the diet claim this can help eliminate toxins, boost energy, improve skin appearance and promote weight loss. However, despite the claims, the human body already has sophisticated ‘detoxification’ built into it (i.e., liver, kidneys, lymphatic and immune systems).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/25522674/?ref=alphabetguides.com) Juice diets typically emphasise nutrient-rich combinations of fruits and vegetables. However, during the juice extraction process, most of the dietary fibre is removed, leaving behind a nutritious but fibre-less liquid. Common ingredients include [leafy greens](https://www.alphabetguides.com/superfood-leafy-greens/) (kale, spinach, celery), cruciferous vegetables (broccoli, cabbage), fruits ([apples](https://www.alphabetguides.com/an-apple-a-day-keeps-the-doctor-away-a-review/), berries, citrus), and roots (carrots, beets, ginger). --- ## Example foods and dishes - **Breakfast:** Green juice (kale, spinach, celery, cucumber, apple, lemon) *or* Orange-carrot-ginger juice - **Lunch:** Beet-apple-celery-ginger juice *or* Watermelon-mint juice - **Snack:** Lemon water *or* Coconut water - **Dinner:** Tomato-cucumber-bell pepper juice with cayenne pepper *or* Green juice with added spirulina or protein powder - **Dessert:** Berry juice blend (strawberry, blueberry, raspberry) - **Drinks:** Herbal tea, coconut water, water & lemon --- ## Pros Evidence supporting health benefits from juice diets is limited. Some short-term juice diets may produce *temporary* improvements in some health markers (e.g., gut microbiome, nitric oxide levels, and oxidative stress). However, there’s little quality evidence supporting any long-term health benefits.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/28526852/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/39940316/?ref=alphabetguides.com) Moderate consumption of 100% fruit juice (around 150-200 mL a day), as part of a balanced diet (i.e., not just a juice diet), does improve nutrition and has some ([cardiovascular](https://www.alphabetguides.com/tag/heart-health/)) health benefits. Fruit and vegetable juices do provide concentrated amounts of some specific micronutrients (e.g., vitamin C, folate, potassium, and various antioxidants).[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC11723140/?ref=alphabetguides.com) For people with poor baseline fruit and vegetable intake, juices may increase exposure to some beneficial plant compounds; however, this is really ‘juice supplementation’ rather than ‘juice diets’.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/38227336/?ref=alphabetguides.com) ## Cons While providing certain vitamins and minerals, these diets lack essential macronutrients, including adequate [protein](https://www.alphabetguides.com/plant-based-protein/), healthy fats, and, critically, dietary fibre. The juicing process removes nearly all fibre content from fruits and vegetables. Relying solely on juice results in poor nutritional balance and increases the risk of nutrient deficiencies.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/25522674/?ref=alphabetguides.com) Short-term weight loss, when achieved, typically results from calorie restriction and is rarely sustained after returning to normal eating (typical [yoyo dieting](https://www.alphabetguides.com/yoyo-diet/)). Excessive juice consumption is also linked to tooth decay, diarrhoea, poor blood sugar control, and increased risk of obesity.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/38227336/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/29124370/?ref=alphabetguides.com) Practical adherence to the diet (long-term) is usually poor due to limited food variety, high costs, hunger, and social barriers. Most people cannot sustain juice-only diets beyond a few days, and the restrictive nature makes them incompatible with normal social eating behaviour. Commercial juice cleanses (the ones you buy or subscribe to) are expensive and inaccessible to many people. Safety concerns also include gastrointestinal issues, electrolyte imbalances, blood sugar fluctuations, and interactions with some medications. Prolonged juice fasts may cause fatigue, headaches, dizziness, and muscle loss. The diet is not appropriate for quite a few groups of people (e.g., children, pregnant or breastfeeding women, individuals with diabetes, or those with a history of eating disorders).[\[7\]](https://pubmed.ncbi.nlm.nih.gov/8892177/?ref=alphabetguides.com) --- ## Bottom Line A glass of 100% fruit or vegetable juice, as part of a varied whole food diet, is fine and may be good for your health. But juice-only diets lack evidence for any health benefits beyond temporary weight loss and offer no advantages over consuming whole fruits and vegetables. In addition, they carry notable nutritional risks, are not sustainable, and offer few proven benefits beyond short-term outcomes from calorie restriction (which are only applicable for some people). --- ## Overall Score: **★★☆☆☆** - Health Benefits: **★★☆☆☆** - Nutrition: **★★☆☆☆** - Weight Control: **★★☆☆☆** - Ease to Follow: **★★☆☆☆** - Safety Profile: **★★☆☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

URL: https://www.alphabetguides.com/what-is-cortisol/ Last updated: 2026-09-22T09:47:49.000Z summary - Cortisol peaks within an hour of waking, then declines throughout the day. Disrupting this daily pattern is where problems begin. - Short cortisol spikes lasting minutes are fine. It is "chronically" elevated cortisol levels (persisting for days or weeks) that cause harm. - Persistently high cortisol increases visceral fat, suppresses testosterone, impairs sleep, weakens your immunity, and increases inflammation. Cortisol is a steroid hormone produced by your adrenal glands in response to stress, and it affects almost every system in your body. In this article, we’ll go through what cortisol is, what it does, what happens when levels run too high, and why this misunderstood molecule is both essential to life and potentially harmful. You've probably heard cortisol described as the 'stress hormone' — something to be crushed, detoxed, or suppressed at all costs. But framing it in this way misses the truth. Cortisol is one of the most important things your body makes. Without it, you couldn't get out of bed in the morning, respond to an emergency, or fight infections. The real question isn't whether cortisol is good or bad. It's whether your cortisol is doing the right thing, at the right time, in the right way. ## What is cortisol? (and why your body needs it) Cortisol is a hormone, a steroid, and a glucocorticoid — and all three of these labels are correct. It's a hormone because it's released into the bloodstream to maintain the health of tissues and organs. It's a steroid because it's synthesised from cholesterol (just like [testosterone](https://www.alphabetguides.com/testosterone-and-muscle-growth/)) and shares the same chemical structure that all steroid molecules do. It's a 'glucocorticoid', and the most important one the human body makes. Its primary role involves regulating “glucose” (blood sugar); that's where the 'gluco-' bit comes from. The 'corticoid' part of that name tells you where it's made: the 'cortex' (outer layer) of your adrenal glands, which sit on top of each of your kidneys. ## How is cortisol made and released? Your brain controls how much cortisol you make. When your brain detects a 'stressor', it sends a signal down to your adrenal glands that tells them to start making and releasing cortisol. Stressors can come from many different places:[\[1\]](https://pubmed.ncbi.nlm.nih.gov/12377295/?ref=alphabetguides.com) - Physical stressors like exercise or extreme temperatures - Physiological stressors like illness, infection, poor sleep or nutrition - Psychological stressors like work pressure, financial worries, bereavement, loneliness or conflict. It’s not all negative, though. Cortisol can even rise (moderately) in excitement or anticipation of something good — it's a response to “arousal”, not just negative stressors. There is always cortisol in your system, so you are always making it, but it doesn’t stay flat throughout the day either. Just like your [sleep hormones](https://www.alphabetguides.com/how-to-sleep-better/), cortisol also follows a semi-regular pattern throughout the day (a “circadian rhythm”). Cortisol should (ideally) be at its lowest in the evening and before you go to bed. It then begins to rise in the early morning hours and peaks within the first hour of waking — known as the “cortisol awakening response”.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/28578301/?ref=alphabetguides.com) As much as it may feel like it, that early morning cortisol spike isn’t a sign of stress; it’s your body’s natural alarm clock. It gets your metabolism, immune system and brain going, ready for the day. Problems arise when this rhythm becomes disrupted — which is where cortisol’s bad reputation comes from. ## What does cortisol actually do in your body? Cortisol's main job is to mobilise your 'resources' when your body needs them most. This includes:[\[3\]](https://www.ncbi.nlm.nih.gov/books/NBK538239/?ref=alphabetguides.com) - Raising your blood sugar levels, which you need if you detect a threat that you need to run from. - Helps control how much fat you are storing and burning, and your appetite. - Prevents your immune response from getting out of control. This is why 'synthetic' (man-made) forms of cortisol (like hydrocortisone and prednisone) are prescribed to control inflammation. - It keeps your blood flowing when it’s needed by controlling your blood pressure and fluid balance in your body. - It helps your brain store memories, process emotions correctly and keep you alert, which is why it can affect your mood and brain power when out of control. ## So is cortisol good or bad? The honest answer is both. Acute cortisol “spikes”, the kind that last minutes, are genuinely protective and necessary. However, consistently elevated cortisol levels are not good. The difference between cortisol as hero and cortisol as villain is almost entirely a matter of how long the “spike” is! --- ## What are the symptoms of high cortisol? When cortisol runs high for a long time, whether it's from work, overtraining, poor sleep, or a medical condition, it goes on to affect your body in the same way.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/28856337/?ref=alphabetguides.com) - **Cognitively**: You may notice brain fog, difficulty concentrating, and poor memory. Many people describe feeling "wired but tired" — mentally restless yet physically exhausted. - **Emotionally**: It is linked to anxiety, irritability, and low mood. It does this by reducing activity in the rational part of your brain (your 'prefrontal cortex') while increasing activity in the threat-detection system (your 'amygdala'). - **Physically**: Symptoms can include poor sleep quality, increased appetite (particularly for high-fat and high-sugar foods), muscle weakness, slow recovery from exercise or illness, getting ill more often, and skin damage. ## Does high cortisol cause weight gain and belly fat? Cortisol does promote fat storage, and even worse, it drives fat around your internal organs (“visceral fat”). This is sometimes referred to as “cortisol belly” and is one of the worst types of fat, being linked to several serious health conditions.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/12119665/?ref=alphabetguides.com) Cortisol also causes you to gain fat by redirecting the energy you eat away from places where it can be burned to places where it is stored (like your belly, legs, arms and hips). Thirdly, cortisol also stimulates your appetite, particularly cravings for calorie-dense [“comfort foods”](https://www.alphabetguides.com/ultra-processed-food-an-introduction/). **So: yes**. Consistently elevated cortisol can give you a “cortisol belly” and make you gain weight. But not on its own. Diet, physical activity, sleep quality and genetics also play a role. ## How long does it take cortisol to return to normal? How long is a spike, and when does a spike turn into a problem? There is no precise answer. But after being exposed to a stressor, cortisol typically returns to normal levels within 1-2 hours. The speed of the recovery will depend on how intense or long the stressor is, how you react to it, how well you are, how fit you are, and your social support and environment.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/20105052/?ref=alphabetguides.com) There are things you can do to reduce your cortisol spikes and return them to normal levels more quickly. Persistent stressors that appear in your life all too frequently are hard to resolve because you can never fully switch off your cortisol response. This is why sustained stress (like from work, relationships or financial insecurity) can keep cortisol elevated for weeks or months. The best thing you can do is to (if you can) avoid these in the first place. --- ## Frequently Asked Questions _This post is for subscribers only._ ### How to Increase Testosterone Naturally Through Diet URL: https://www.alphabetguides.com/the-testosterone-diet/ Last updated: 2026-09-04T13:56:47.000Z summary - Diets below 20% fat reduce testosterone. So 25 to 35% of your calories should come from fat if you want to keep your testosterone levels high. - Severe calorie restriction also suppresses testosterone. Keep deficits under 20% of maintenance and avoid dieting for too long (months). - Most testosterone boosters lack credible evidence. Zinc, magnesium, and vitamin D only support production if you are already deficient in them. Testosterone is the primary male sex hormone responsible for your energy, muscle mass, libido, and mood (among many other things). What you eat plays a crucial role in keeping it 'optimised'. In this article, we'll take a look at “testosterone-boosting” foods, food groups, which supplements work, what to avoid, and what changes you can make. The foods you eat every day can affect how well your body produces (and responds to) testosterone. Getting it wrong can quietly suppress it for weeks or months before you even notice anything. ## Why your total testosterone level isn't the whole story First, let's define what ['optimising' your testosterone](https://www.alphabetguides.com/testosterone-blueprint/) actually means. Most people assume this means having a high “total T” reading on a blood test. How many ng/dL do you have? 1000 ng/dL, everything is great; 300 ng/dL, not so good, right? But your total testosterone is only part of the picture. A significant portion of testosterone in your blood is bound to a protein called “sex hormone-binding globulin” (SHBG), which makes it “biologically inactive” (meaning it doesn’t interact with your body). Only "free" testosterone (i.e., not bound to anything) is actually available for your body to use. You can have normal total testosterone levels while still experiencing the effects of [low testosterone](https://www.alphabetguides.com/andropause/) if your SHBG is too high or if your body's hormonal signalling is disrupted in some way. Testosterone is produced in your testes, but the amount that you produce is controlled by your brain, which is sensitive to your nutritional state, stress levels, sleep and body composition. So if you want to optimise your testosterone, it is really a “whole systems” approach — not just manipulating a single marker on your lab results. ## Signs your testosterone may be low Low testosterone is also not clear or easy to diagnose from its symptoms, but some of the most common signs include: - Persistent low energy or fatigue, even with [adequate sleep](https://www.alphabetguides.com/tag/sleep/) - Reduced sex drive or difficulty with erections - Poor sports performance, muscle loss or difficulty [building muscle](https://www.alphabetguides.com/testosterone-and-muscle-growth/). - Increased body fat, particularly around the abdomen - Low mood, irritability, or difficulty concentrating If several of these things sound familiar, your diet could be a contributing factor. And the good news is that some nutritional changes can improve your testosterone, often within weeks.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC2834355/?ref=alphabetguides.com) --- ## How your diet directly affects testosterone production Testosterone is made from cholesterol. This means your body cannot produce testosterone without adequate amounts of dietary fat. Eating too little fat reduces the availability of this building block and will blunt the production of testosterone. Beyond fat, your overall calorie intake acts as a signal to your testosterone production system. When your calorie intake drops too low, your body interprets this as a 'starvation' response and goes into "survival mode". Your body will go on to dial down your testosterone production; this can happen in just a few days of an aggressive energy deficit.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/30063407/?ref=alphabetguides.com) Several micronutrients (like zinc, magnesium and vitamin D) are required in certain amounts to produce testosterone. So, if you are deficient in any of these micros, your production of testosterone will slow or stop. Correcting these deficiencies can restore normal testosterone levels, but mega-dosing beyond adequate amounts doesn’t seem to speed up or increase testosterone production. ## The best foods and nutrients to support testosterone _This post is for subscribers only._ ### MIND Diet: A Review URL: https://www.alphabetguides.com/mind-diet/ Last updated: 2026-09-22T10:07:11.000Z summary - The MIND diet is designed to reduce cognitive decline and dementia risk by eating foods that are good for your brain health. - Older adults who follow that diet tend to have slower cognitive decline, better memory, and lower rates of Alzheimer's disease. - However, the diet has no advantage over other healthy diets, suggesting the overall health profile of the diet is the most important factor. The “MIND” diet is short for “Mediterranean-DASH Intervention for Neurodegenerative Delay”. As the name suggests, it combines elements of two well-established healthy eating patterns: the[ Mediterranean diet](https://www.alphabetguides.com/mediterranean-diet-review/) and the “DASH diet” (Dietary Approaches to Stop Hypertension). The result is a dietary pattern specifically designed to support brain health. The diet places particular emphasis on ten "[brain-healthy](https://www.alphabetguides.com/tag/brain-health/)" food groups: [leafy green](https://www.alphabetguides.com/superfood-leafy-greens/) vegetables (at least 6 servings per week), all other non-starchy vegetables, berries, nuts, whole grains, beans and legumes, fish, poultry, and [olive oil](https://www.alphabetguides.com/superfood-olive-oil/). At the same time, it limits five food groups considered harmful to brain health: red meat, butter and margarine, cheese, pastries and sweets, and [fried or fast food](https://www.alphabetguides.com/ultra-processed-food-diet/). Unlike more rigid diets, the MIND diet does not require calorie counting or the [elimination of entire food groups](https://www.alphabetguides.com/diet-framing/). Its scoring system rewards consistency (i.e., how often you eat the right foods) rather than demanding perfection at every meal. The rationale is that nutrients found in abundance in these foods (vitamin E, B vitamins, [omega-3 fatty acids](https://www.alphabetguides.com/superfood-oily-fish/), and polyphenols) help protect the cells in your brain, reduce oxidative stress, and inflammation (which goes on to affect the brain). --- ## Example Foods & Dishes - **Breakfast:** - Porridge with mixed berries, walnuts, and a drizzle of honey - Whole-grain toast with avocado, a poached egg, and sliced tomato - **Lunch:** - Leafy green salad with grilled chicken, olive oil dressing, and mixed seeds - Lentil and vegetable soup with whole-grain bread - **Snack:** A small handful of almonds with a punnet of blueberries - **Dinner:** - Baked salmon with roasted sweet potato and steamed spinach - Chicken and vegetable stir-fry with brown rice and olive oil - **Dessert:** Fresh berry compote with a spoonful of Greek yoghurt - **Drinks:** Water, herbal tea, green tea, black coffee --- ## Pros Research shows that higher adherence to the MIND diet is associated with slower cognitive decline, better cognitive function and lower risk of dementia and Alzheimer's disease in older adults.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/26086182/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/38961421/?ref=alphabetguides.com) Some studies have reported that the MIND diet outperforms the Mediterranean or [DASH diets](https://www.alphabetguides.com/dash-diet/) alone. Lower rates of mental health issues (depression and distress), improved “cognition” (i.e., memory, attention and task performance), better mood and quality of life have also been reported.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31209456/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/36071944/?ref=alphabetguides.com) Beyond cognition, the diet is linked to good [cardiometabolic health](https://www.alphabetguides.com/tag/heart-health/): better blood lipids, lower blood pressure, lower inflammation, improved blood sugar control, and lower rates of cardiovascular disease and stroke. This makes sense, given that it is based on two of the healthiest diets out there.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/37908631/?ref=alphabetguides.com) From a nutritional standpoint, the MIND diet is well-balanced and rich in nutrient-dense whole foods. It provides fibre, healthy fats, [plant protein](https://www.alphabetguides.com/plant-based-protein/), and a broad array of vitamins and minerals. No major food groups are eliminated (but several unhealthy foods are), and there is little risk of nutrient deficiency when the diet is followed as intended. Practical adherence is pretty good (comparably) — the diet is flexible, the foods are familiar to many people in Western countries, and it does not require expensive specialist foods or rigid meal timing. ## Cons The supporting evidence for its superior brain-health benefits claims is not always consistent. Some high-quality research has shown that a calorie-controlled MIND diet did not outperform other healthy calorie-controlled diets (although they both improved health outcomes).[\[6\]](https://pubmed.ncbi.nlm.nih.gov/37466280/?ref=alphabetguides.com) This does not mean the diet is completely ineffective, but it does mean the specific “brain health” benefits of the diet have been questioned. People who eat better tend to also have healthier lifestyles: they exercise more, sleep better, and have higher incomes — all of which are also good for the brain.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/33989093/?ref=alphabetguides.com) For weight loss and maintaining a healthy body weight, the MIND diet offers no advantage over other [calorie-restriction](https://www.alphabetguides.com/hara-hachi-bu-an-ancient/) healthy diets. That said, it is not specifically designed for weight loss, but studies still show comparable weight outcomes compared to other healthy eating patterns when calorie intake is matched.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/35190536/?ref=alphabetguides.com) The diet also requires some planning and cooking, which can be a barrier for people with busy schedules, limited food access, or a lack of cooking skills.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/32799963/?ref=alphabetguides.com) --- ## Bottom Line The MIND diet is a thoughtfully constructed, nutritionally sound eating pattern with *reasonably* strong evidence that it supports brain and cardiometabolic health. It is accessible, flexible, healthy and safe for most adults, although there have been some questions about how superior its health effects are compared to its base diets (or other healthy diets). For people who want a practical, sustainable diet that is good for both brain and body, the MIND diet is an excellent choice, but so are its predecessors. --- ## Overall Score: _This post is for subscribers only._ ### Why Running is Better Than Walking: 8 Reasons URL: https://www.alphabetguides.com/why-running-is-better-than-walking/ Last updated: 2026-10-02T14:22:06.000Z summary - Seventy-five minutes of running per week is equivalent to 150 minutes of brisk walking — meaning equal health benefits in half the time. - Running as little as 5 minutes per day at a slow pace is associated with better life expectancy and lower cardiovascular disease risk. - Running suppresses the hunger hormone ("ghrelin") for longer than walking, giving it an advantage for those managing calorie intake. Running and walking are both excellent forms of exercise — but they are not the same. In this article, we explore eight reasons why running delivers unique health and fitness benefits that walking alone cannot match. For most people, most of the time, [walking](https://www.alphabetguides.com/why-walking-beats-running/) is the more practical, accessible, and sustainable choice. But if your body can handle it, running delivers a set of physiological changes that walking simply cannot replicate. The greater stress it places on your heart, lungs, bones, muscles, and nervous system is not a downside — it’s the driving force behind its health benefits. --- ## #1\. More health benefits per minute of exercise Running can burn three times as many calories per minute, and up to twice as many calories per mile. Studies have shown similar health effects between walkers and runners when the total amount of calories burned is the same. However, running beats walking when the total amount of *time* spent exercising is the same.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/23559628/?ref=alphabetguides.com) Put simply, a 30-minute run produces greater health benefits than a 30-minute walk. In fact, a 15-minute run will probably beat, or at least equal, the health benefits of a 30-minute walk. So, for people with busy lives who don’t have time for exercise, running is a more efficient use of that time, as the same cardiovascular and metabolic health benefits can be achieved in half the time. **Pro Tip:** The current physical activity guidelines recognise this — 75 minutes of vigorous activity (like running) per week is considered equivalent to 150 minutes of moderate activity (like brisk walking).[\[2\]](https://pubmed.ncbi.nlm.nih.gov/17762377/?ref=alphabetguides.com) --- ## #2\. Superior cardiovascular adaptations Running places a substantially higher demand on the heart and blood vessels than walking does. Over time, this greater stress usually produces greater cardiovascular adaptation: stronger, more efficient heart muscles, lower resting heart rate, better (more flexible) blood vessels, [lower blood pressure](https://www.alphabetguides.com/exercise-lowers-blood-pressure/), and better circulation. Higher-intensity exercise has been shown to produce superior improvements in cardiovascular risk markers compared to moderate-intensity exercise, even when the total amount of exercise is the same.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/16377300/?ref=alphabetguides.com) For people looking to meaningfully improve their heart health, not just maintain it, running will be a more powerful exercise to improve their health. --- ## #3\. Running improves VO2max more than walking VO2max, the maximum volume of oxygen your body can use during intense exercise, is one of the single strongest predictors of long-term health and longevity, and you can meaningfully improve it. Low VO2max is associated with increased risk of many diseases, reduced quality of life and reduced life expectancy. Walking can modestly improve VO2max in people who are inactive. But running, at moderate-to-hard efforts, is one of the most effective and efficient ways to improve VO2max. A higher VO2max means your heart, lungs, and muscles operate more efficiently at every exercise intensity — including during everyday activities (making them easier to do). So, improving it through running is one of the best long-term investments you can make in your health. ### Workout — VO2max builder After a 5-minute warm-up walk, run at a "comfortably hard" pace (you can speak only in short phrases) for 20–30 minutes, three times per week — progress by adding 5 minutes every week or two. Read our articles on how to [improve your VO2max](https://www.alphabetguides.com/improve-your-vo2max/) and how to calculate and use [training zones](https://www.alphabetguides.com/what-are-training-zones/) to improve your training --- ## #4\. Running builds stronger bones — especially as you age Bone is a living tissue that responds and adapts to the demands placed upon it. When your bones are repeatedly exposed to stress (via impact forces), they’ll adapt and get stronger. While walking does stimulate bone-building benefits, the higher forces that your body is exposed to during running produce a stronger signal to improve bone strength and bone density.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/16731064/?ref=alphabetguides.com) This matters more as you get older. Osteoporosis affects a lot of seniors and significantly increases fracture risk. Running regularly and starting earlier in life can help build and preserve bone health. For those at risk of osteoporosis who cannot run, brisk walking is still beneficial — but for those who can run, it offers more benefits for your bones. --- ## #5\. Running builds and strengthens your muscles Running engages all the muscles of the lower body (glutes, hamstrings, quadriceps, calves), putting them under greater load than walking does. This greater demand over time translates to greater [muscle strength](https://www.alphabetguides.com/muscle-adaptation/), endurance, and coordination. Greater muscle mass and strength are associated with better health, functional capacity, and lower injury risk as you age. The “propulsive phase” of running, where you push off the ground, activates your calves, glutes and hamstrings in a way that walking can’t. Running *won't* replace [strength training benefits](https://www.alphabetguides.com/minimalist-muscle-growth/), but its muscular demands are meaningfully greater than walking's are. ### Workout: Hill repeats for muscles Find a moderate incline and run uphill for 30–60 seconds at a strong effort, then walk back down to recover. Repeat 6–10 times. Hill running dramatically increases the use of your quads and calves compared to flat-ground walking or running.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/9390983/?ref=alphabetguides.com) --- ## #6\. Running trains your lungs more effectively The lungs, just like the heart, bones, and muscles, will adapt to the demands placed on them. As you’re probably aware, if you’ve ever been on a hard run, it significantly increases how often and deeply you breathe, which strengthens your respiratory muscles. This improves how efficiently you breathe as you become better at extracting and delivering oxygen into your body. Walking doesn’t elevate your breathing rate to the same degree as running does. For people with respiratory conditions (like asthma, COPD, pneumonia or viral infections), *supervised* running programmes have been shown to improve lung function and general health.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/17762377/?ref=alphabetguides.com) Getting oxygen into your body efficiently isn’t just for athletes and powering exercise high-end performance — it also underpins your energy levels, brain power, and resilience throughout the day when you're not exercising. --- ## #7\. Running Suppresses Appetite More Than Walking High-intensity exercise, like running, suppresses your 'hunger hormone**'** (ghrelin) for longer than lower-intensity exercise does. This means that you’ll eat less food after a hard run compared to a gentle stroll.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/36747559/?ref=alphabetguides.com) For people who want to [lose weight or lose fat](https://www.alphabetguides.com/tag/fat-loss/), running may have an edge over walking. Higher-intensity exercise may make it easier for those who are following a calorie-restricted diet. However, don’t give up on walking entirely. Research has shown that both walking and running naturally increase the amount of the hunger-suppressing GLP-1 (the 'fat jab' hormone) and another one called PYY. --- ## #8\. Running extends life expectancy — even at slow speeds While both walking and running improve health, quality of life and life expectancy, the evidence on running is more convincing. Even running as little as 5 minutes a day at slow speeds (10-minute mile pace or slower) is associated with better life expectancy and lower rates of cardiovascular disease.[\[7\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4131752/?ref=alphabetguides.com) Running is enough in itself to improve your health without worrying about volume, times, heart rates or your pace. Those who kept running regularly for at *least* 6 years were in the best health and lived longest. So the message is clear: running consistently, at any pace, is one of the most powerful single lifestyle habits you can do for a longer, healthier life. --- ## How to start running: a beginner's guide When starting, it shouldn’t be about speed but consistency and avoiding injury. _This post is for subscribers only._ ### Why Walking is Better Than Running: 8 Reasons URL: https://www.alphabetguides.com/why-walking-beats-running/ Last updated: 2026-09-22T09:50:47.000Z summary - Calorie-for-calorie, walking reduces hypertension, high cholesterol, and diabetes risk as effectively as running. - At under 65% of max heart rate, the body uses fat as its primary fuel — making brisk walking more effective for fat burning than running (calorie-for-calorie). - Running generates over twice the impact forces of walking, making it significantly harder on joints, bones, and tendons. Walking and running are the two most natural forms of human movement. In this article, we go through eight evidence-based reasons why walking beats running. We also go over practical ways to walk more, walk better, and make walking a permanent part of your life. Running has a powerful image (or rather, a powerful marketing message). Marathons, 5K apps, government schemes and clothing campaigns have convinced much of the world that if you're not [running](https://www.alphabetguides.com/why-running-is-better-than-walking/), you're not really exercising. But the evidence tells a more nuanced (and potentially a more optimistic) story. For the vast majority of adults, particularly those who are sedentary, older, overweight, managing a health condition, or simply time-pressed, walking can be the smarter choice. ## #1\. Walking delivers nearly identical health benefits to running The most important thing to understand about walking versus running is that, calorie-for-calorie and mile-for-mile, they deliver strikingly similar health outcomes. A large study on 48,000 people found that when total “energy expenditure” was matched, walking produced the same health benefits. It reduced the risk of high blood pressure, high cholesterol, heart disease and diabetes by the same amount as running did. In practice, this means that you’ll need to walk*further* than you run (about 50% further for a brisk walk) to match the number of calories burned.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/23559628/?ref=alphabetguides.com) But for most people, walking the extra distance is still more achievable and sustainable than running all of it. ## #2\. Walking has a lower injury rate When you run, you only have one foot on the ground, whatever the pace you're running at. With every stride, that foot absorbs the impact of over twice your body weight. During a long run, this means hundreds of impacts per leg. Injury rates among runners are comparatively high, with runner’s knee, shin splints, IT band syndrome, stress fractures, Achilles tendonitis and jogger’s heel commonly reported.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/17473005/?ref=alphabetguides.com) By contrast, walking generates less than half the forces that running does, making it gentler on the bones, joints, tendons, and muscles. For people with arthritis, osteoporosis, obesity, or a history of lower limb injury, walking is not merely preferable to running — it may be the only safe option. Getting injured is not just about the pain (although that is important as well); it also derails momentum, your motivation, and confidence and can set your fitness goals back even further. 💡 If you've been sedentary and want to start exercising, begin working towards getting through four 20-minute brisk walks a week before considering any running at all. Build your body's strength and stamina first. ## #3\. Walking is easier to sustain long-term The rates at which people start and then stick to exercise are poor. Effort, exertion, and exhaustion all matter. Running is hard. For inactive people, exercise can feel unpleasant and a chore. Walking, at a self-selected pace, sits in an effort zone that more people find sustainable, even enjoyable. Improving your health via exercise is built on consistency — months and years of it, not days. A brisk 20-minute daily walk will have better health-promoting benefits than someone who runs hard three times a week, hates it, and quietly gives up in February. The best exercise is the one you actually do — and for most people, that is walking. ## #4\. Walking is a superior fat-burner Running burns more calories per minute than walking, but that doesn’t automatically make it better for fat loss. At [moderate walking intensities](https://www.alphabetguides.com/what-are-training-zones/) (under 65% max heart rate), your body uses fat as its primary fuel.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/15212756/?ref=alphabetguides.com) At higher intensities, the fuel shifts to carbohydrate. This means that if you burn the same calories, a brisk walk will burn more fat than a run. ### A fat-loss focused walking workout 60 minutes at a pace where you can speak in full sentences but feel warm and moderately breathless (about 100 steps per minute). Do this before breakfast, in a [fasted state](https://www.alphabetguides.com/should-you-exercise-fasted/), three to four times per week. ## #5\. Walking fits into your life more easily You can walk to work, to the shops, to a friend’s house, to a meeting, or to the school drop-off — and in doing so, you’ll meaningfully add exercise into your daily life without the extra effort of setting time aside. No parking, no traffic, no changing room, gym bags or showers needed. This is not trivial. One of the main reasons why people don’t exercise is *time*! Walking overcomes that barrier more effectively than other forms of exercise. “Active commuting” — walking or cycling to and from work — is linked to better health outcomes. So, simply replacing your car or bus journey to work with a walk can meaningfully improve your health. You can’t run to the office in your work clothes, but you can walk there.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/28424154/?ref=alphabetguides.com) 💡 Map any regular journey you currently make by car, bus, or public transport and identify which ones fall within a 20–30 minute walking distance. Start replacing them one per day per week. ## #6\. You do things while you walk Running at a moderate-to-hard pace demands conscious effort and most of your attention; walking does not. This opens up a free 'window of time' to do other things that may make it more enjoyable (and potentially healthier). Take “social walks” with friends or family, which double as both exercise and socialising. You can make business calls, listen to audiobooks or podcasts, take a “walking meeting” or just let your mind wander in a way that can promote creativity, problem-solving, or relieve stress. Walking (particularly outdoors) can improve mental health and your mood. A run in the park with your headphones in is pleasant. A slow walk, taking in your surroundings, using all your senses, is an entirely different (and restorative) experience. ## #7\. Walking is good for recovery If high-intensity training like running, [weightlifting](https://www.alphabetguides.com/minimalist-muscle-growth/), cycling, or sports is part of your routine already, walking can be used to help recovery. Walking is a form of 'active recovery' that promotes blood flow to the muscles without adding extra stress requiring recovery in itself. It has been shown to reduce the '[delayed onset of muscle soreness](https://www.alphabetguides.com/doms/)' (DOMS) and helps keep daily movement levels up even on rest days. Unlike complete rest, walking keeps the body active, burning calories, without prolonging recovery any further.[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5932411/?ref=alphabetguides.com) For this reason, many athletes will add a low-intensity walk to their programmes. For beginners and recreational exercisers, a 20-minute walk on rest days is almost always better than doing nothing. ### A "recovery workout" The day after a hard training session, take a 20-30 minute easy walk at a comfortable, conversational pace. Aim for flat terrain and focus on relaxed breathing. ## #8\. Walking is accessible to almost everyone For people who are overweight or obese, joint loading during exercise can become an issue. The same goes for older adults. People with cardiovascular health issues, joint replacements, chronic pain conditions, or other disabilities, at best, will have difficulty running, and at worst, it can risk hospitalisation. Running can be intimidating for beginners, and it can feel performative in public, whereas walking doesn’t. Virtually anyone can walk. It can be done at any age, any fitness level, body size or (almost) any health condition. It requires no technique, no equipment, no special clothing, no warm-up, and no recovery time. The barrier to entry is zero. An 85-year-old with osteoarthritis and a 25-year-old athlete can both benefit from the same daily walk — and that “universality” is perhaps walking's most underrated quality. No other type of exercise comes close. --- ## How to walk more and walk better: practical strategies _This post is for subscribers only._ ### Elimination Diet: A Review URL: https://www.alphabetguides.com/elimination-diet/ Last updated: 2026-09-22T13:49:43.000Z summary - The elimination diet is used to identify your body's reaction to different foods. - The diet is effective for identifying specific foods or food groups for certain medical conditions (e.g., allergies and intolerances). - The diet should not be done without a good reason and without medical supervision. It is not for improving general health or for weight loss. The elimination diet starts by removing specific foods or food groups that are suspected of causing ‘adverse reactions’ in your body. It is then followed by the planned reintroduction of certain foods to identify the triggers. Unlike permanent dietary patterns, elimination diets are a temporary investigative tool that is used to manage food allergies, intolerances, and certain gut or inflammatory conditions. The diet typically requires careful planning and (sometimes) professional supervision to avoid any (unintended) nutrient deficiencies. Common elimination protocols include the ‘six-food’ elimination diet (removing milk, egg, wheat, soy, nuts, and seafood), ‘four-food’ elimination diet (typically excluding milk, egg, wheat, and soy), and more targeted single-food eliminations based on suspected triggers. The process generally involves three phases: elimination (removing suspected foods for 2-6 weeks), observation (monitoring changes in symptoms), and then reintroduction (adding foods back individually to identify specific triggers). By eliminating suspected foods and observing the response, you should be able to identify specific dietary triggers. This diet fundamentally differs from ‘lifestyle diets’; it is an exploratory medical tool, not a long-term eating pattern. --- ## Example foods and dishes - **Breakfast:** - Rice cereal with rice milk and pear - Plain turkey sausage with steamed zucchini - **Lunch:** - Grilled chicken, white rice and steamed carrots - Baked sweet potato with plain ground turkey - **Snack:** - Plain salted rice cake - Sliced apple with peanut butter - **Dinner:** - Grilled lamb with quinoa and steamed green beans - Poached cod with plain white rice and boiled spinach - **Dessert:** Baked pear with cinnamon - **Drinks:** Herbal tea, rice milk --- ## Pros Elimination diets are effective for identifying food allergies and intolerances. Targeted elimination of certain foods can reduce symptoms of dermatitis, IBS, and eosinophilic esophagitis (throat inflammation).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/28884902/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/36731591/?ref=alphabetguides.com) By systematically removing and reintroducing foods, people can pinpoint triggers that contribute to inflammation, gut function, or behavioural symptoms. This individual approach not only improves the control of symptoms but may also lessen dependence on medication and improve long-term health.[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC10960192/?ref=alphabetguides.com) When professionally supervised with appropriate dietary guidance, supplementation, and hypoallergenic food products, health outcomes and nutrition can be maintained or actually improved (particularly in children with food allergies). The diet's investigative nature provides important information about individual food sensitivities that other approaches may miss.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/27418957/?ref=alphabetguides.com) ## Cons Evidence for elimination diets remains limited beyond specific allergies or intolerances. The evidence for the diet's positive effects on IBS is debatable, and the same goes for *some* other conditions as well.[\[5\]](https://www.ncbi.nlm.nih.gov/books/NBK599543/?ref=alphabetguides.com) The diet's restrictive nature can also create risks, specifically regarding adequate intake of macronutrients, vitamins, and minerals. These risks are also amplified in children and mothers who are breastfeeding. Practical adherence to the diet also presents a major issue. Cost, limited accessibility to specialised foods, social barriers, and psychological burden can impair long-term compliance. Increased anxiety about food choices and social situations represents another notable barrier. Additionally, the diet may create problematic relationships with food for some people, and the restrictiveness makes maintaining the diet difficult for many families, with low to moderate long-term adherence rates at best.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/29611076/?ref=alphabetguides.com) Safety concerns include nutrient deficiencies, growth and developmental issues in children, and anxiety or eating disorders. Safety risks will also substantially increase without proper supervision. So, while generally safe under professional management for targeted conditions, unsupervised or overly broad elimination carries meaningful risks. The diet is not intended for weight management and offers little benefit for [weight loss](https://www.alphabetguides.com/tag/fat-loss/). --- ## Bottom Line The elimination diet serves as an effective diagnostic and therapeutic tool for specific medical conditions, but should not be undertaken without a medical reason and professional supervision. Evidence supports the targeted use of the diet for people with medical conditions, not for general health or weight management. Success requires multidisciplinary support from a team of professionals, such as gastroenterologists, allergists, and dietitians, to ensure it is done correctly. --- #### Sources 1. Lim NR et al.

How to Calculate & Use Them URL: https://www.alphabetguides.com/what-are-training-zones/ Last updated: 2026-09-14T15:42:25.000Z summary - Training zones are defined by three real physiological thresholds, meaning each zone represents a distinct metabolic "state" unique to each person. - Most endurance athletes spend approximately 80% of their weekly training in zones 1 and 2, using zones 3 and 4 intermittently and strategically. - A 30-minute all-out effort is a reliable field test that can be used to estimate your personal zones without laboratory equipment. Training zones are just intensity “categories” defined by how hard you are training. They range from very easy 'active recovery' exercise intensities to all-out max effort. They are just there to help you exercise at the right intensity for the session. In this article, we’ll go through what training zones are, how many exist, what each one does to your body, how to estimate your unique training zones, and how to use them. ## What are training zones? (and why they matter) Training zones are a range of intensities that are typically expressed as a % of your max, either heart rate (HRmax) or [VO2max](https://www.alphabetguides.com/improve-your-vo2max/). These aren’t just random or arbitrary values; they represent unique 'physiological states' your body enters when you exercise. They're usually based on what "fuel" you’re using (fat or carbohydrate), how much oxygen you're using and what byproducts your body is making to produce energy (e.g., lactate and carbon dioxide). This is important because training at different intensities triggers different adaptations. So the idea is: not all exercise is the same, so doing the right type of training, at the right time, will produce better results rather than training randomly. --- ## How many training zones are there? This is confusing, as there are no universally agreed-upon standards. There are 2, 3, 4, 5, 6 and 7 zone models. However, we think the 3-zone or 4-zone models are the best ones.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/41085254/?ref=alphabetguides.com) This is because each of the zones is bordered by distinct and measurable physiological "boundaries that are split by three well-established physiological "thresholds" that have been measured for decades. So, this means that each zone represents a unique 'physiological state' that is personalised to each person's own unique physiology. They are not based on arbitrary boundaries based on percentages or 1-10 estimates. 1. **First Metabolic "Aerobic" Threshold (MT1)**: It has many names. They are very similar, but are calculated (or measured) slightly differently. Aerobic threshold ('AT1'), ventilatory threshold ('VT1'), and lactate threshold ('LT1') are all examples of it. 2. **Second Metabolic "Anaerobic" Threshold (MT2):** It is also known as the anaerobic threshold (AT2), second lactate threshold (LT2), maximal lactate steady state (MLSS), second ventilatory threshold (VT2), respiratory compensation point (RCP) or critical speed (CS) or power (CP) threshold. 3. **VO2max**: The maximum amount of oxygen your body can use. Any intensity above this threshold is purely anaerobic (without oxygen). ## 3 zone vs. 4 zone model The 4-zone model we use is essentially the same standard 3-zone model that has been used for decades. The extra zone (“zone 4”) we’ve added is used to plan and prescribe high-intensity training using your pace or power output (not based on your heart rate).[\[2\]](https://pubmed.ncbi.nlm.nih.gov/20861519/?ref=alphabetguides.com) Traditionally, zone 4 workouts like high-intensity interval training (HIIT), sprint and speed training haven't been used by endurance athletes. But they are now fairly common and are beneficial for endurance performance. In practice, you can just stick with a simple 3-zone model and call zone 4 "above zone 3", which is just semantics, really. But because there's a range of paces or power outputs above zone 3, we think it is more accurate to call it a "zone" rather than a single intensity. Zone 4 starts from the pace or power at your VO2max and ends with your all-out 100% max or peak pace or power (as fast and hard as you can run, swim, row or pedal: it's a sprint). At the start of zone 4, you are at (or very close to) your HRmax. This means that even if you increase your pace or power output while in zone 4, there will be no further increase in your heart rate (or your VO2). Put simply, if you're using heart rate to estimate, prescribe or monitor your training intensity, there are basically 3 zones (zones 1-3). If you're estimating, prescribing or monitoring off your pace or power output, above your VO2max, there's an extra zone (zone 4). You can't increase your VO2 or HR above their max values, but you can increase your pace or power output above your VO2max or HRmax equivalents. ### Other training zone models The 5-zone training model is popular, being the same as our 4-zone model, only with zone 1 being split into two by an arbitrary value (usually 50-60% HRmax or VO2max). In the 5-zone model, zone 1 is below the arbitrary value (say 60% HRmax) and 'zone 2' sits above it (but below MT1). The extra zone in the 5-zone model ('zone 1') is commonly used to prescribe active recovery. There are also 6-zone and 7-zone models. In these models, zone 5 from the 5-zone model, or zone 4 in our 4-zone model (i.e., all intensities above VO2max), is split into two or three more zones. Intensities around VO2max (zone 5), all-out 100% max (zone 7), and then another zone in between (zone 6), which is defined by when your muscles stop producing lactate (called "vLamax"). --- ## The "4-Zone" Training Model #### Zone 1 - "Light" intensity exercise - under MT1 - < 75% HRmax - <65 VO2max - < 80% 30 min pace - <4 out of 10 effort. #### Zone 2 - "Moderate" intensity exercise - Between MT1 and MT2 - 75–85% HRmax - <65 VO2max - 80–100% 30 min pace - 4–6 out of 10 effort. #### Zone 3 - "High" intensity exercise - Between MT1 and VO2max - 85–100% HRmax - 85–100% VO2max - 100–120% 30 min pace - 7–9 out of 10 effort #### Zone 4 - "Very High" intensity exercise - Above VO2max - 100% HRmax - 100% VO2max - Over 120% 30 min pace - Over a 9 out of 10 effort --- ## What Each Training Zone Does to Your Body ### Zone 1 — Low or light intensity At this intensity, your aerobic system is active but not working hard. Blood flow increases gently, oxygen demand is low, and your muscles rely almost entirely on fat for their energy. This zone promotes recovery without stressing the body. ### Zone 2 — Moderate intensity The end of zone 1 and into zone 2 is arguably the most important intensity for long-term cardiovascular health and endurance performance. This is where endurance athletes will spend a lot of their time training. Towards the middle of zone 2 (and going into zone 3), exercise starts to get hard, being at around your "race pace". Training in this zone will improve performance, but it will also take longer to recover from. So, some coaches don’t like training too much at this intensity, as more efficient performance improvements can be achieved at higher intensities. This is a widely debated topic in the sports science community with opinions on both sides. ### Zone 3 — High intensity This is where you are pushing close to your ceiling. Your heart, lungs and muscles are working hard. You’ll get some of the most efficient stamina improvements (i.e., improvements per minute of exercise). Time spent at this intensity is typically brief (under 20 minutes total) and requires full recovery between sessions. ### Zone 4 — Very high This is near all-out, maximal efforts which last seconds. The predominant energy source for this exercise intensity is not powered by oxygen — you’re using other reserves in your body. These sessions need the longest recovery and are used to improve power output, VO2max and high-intensity exercise performance. --- ## Terminology explained ### Aerobic vs anaerobic exercise Aerobic exercise literally means 'with oxygen.' Your muscles use oxygen to convert fat and carbohydrates into energy — in a sustainable, efficient process. Zones 1 and 2 are primarily aerobic. Anaerobic exercise is when intensity increases past the point where you can use oxygen to generate energy quickly enough. At this point, your muscles turn to other (less efficient) ways to produce energy. These energy-making processes produce a by-product called lactate: this is what predominantly happens in zone 3 and zone 4. ### “Zone 2 training” “Zone 2” has become one of the most talked-about training zones. In the 3- and 4-zone training models, it sits at the end of zone 1 (confusingly) — just below MT1\. It’s a pace where you can hold a conversation easily, burn the most fat, you can maintain it for well over an hour, and you’ll get fitter training in this zone. It’s an efficient zone for training your stamina. Most endurance athletes will spend 80% of their total weekly training in and around zones 1 and 22. ### Lactate threshold This is where a byproduct ('lactate') starts to accumulate in your body, rising above resting levels. This is what differentiates zone 1 (no lactate accumulating) and zone 2 (blood lactate increases). It also splits zone 2 and zone 3, where lactate starts to increase consistently, going up every time you measure it. When training in zone 3, you’ll start to feel more fatigue as more time passes. This is why zone 3 exercise is called "unstable": because your underlying physiology is continually changing as you get more and more tired when training in this zone. Your heart rate, breathing rate, VO2, lactate, body temperature and feelings of fatigue aren't stable; they'll keep drifting up while you're in zone 3\. The key to improving your race performance is to increase your pace and power outputs at which lactate starts accumulating. However, this doesn't mean you have to always train at these threshold intensities (beginning and end of zone 2). In fact, some coaches advise avoiding it! ### Polarised training (80/20) This is where \~80% of sessions are spent in zone 1 and \~20% in zones 3 and 4, with little time spent in zone 2\. Basically, they train at very high or very low intensity, with little moderate intensity training in between MT1 and MT2\. Some researchers (*not* all of them!) have suggested this is more efficient and effective for improving stamina and endurance. Athletes from a lot of different sports tend to gravitate to this type of training naturally.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/24550842/?ref=alphabetguides.com) ### “FatMax” This is the intensity at which your body burns the most fat. It typically occurs in zone 1 or zone 2\. Note that your FatMax is not the same as burning the most calories (that’s in zone 4; more intensity means more calories burned per minute).[\[4\]](https://pubmed.ncbi.nlm.nih.gov/15212756/?ref=alphabetguides.com) It just means the point at which you're burning the most fat. Your diet, fitness level, [hormones](https://www.alphabetguides.com/tag/hormones/), health, and what and when you last ate can shift your FatMax pace higher or lower. --- ## How to calculate your training zones without lab equipment The gold-standard way to know your training zones is to get an exercise physiologist to test you in a lab. However, there are also some field tests you can do yourself. _This post is for subscribers only._ ### What is VO2max & How to Improve It URL: https://www.alphabetguides.com/improve-your-vo2max/ Last updated: 2026-09-15T14:39:26.000Z summary - VO2max is one of the strongest predictors of longevity, with some researchers ranking it above standard blood tests as a measure of health. - "HIIT": particularly intervals of 2+ minutes at approximately 90% effort, is the most time-efficient method for improving VO2max. - As little as two weeks of physical inactivity reduces VO2max. Consistent training is the most important factor for maintaining it long-term. VO2max is your body's maximum capacity to use oxygen (which is usually done during exercise). It is one of the most powerful predictors of both athletic ('endurance') performance and your long-term health prospects. The higher your VO2max, the fitter you are! In this article, we’ll cover what VO2max is, what values are considered healthy, why it matters, and what training methods are most effective at increasing it. ## What is VO2max? VO2max is shorthand for maximal oxygen uptake: the highest rate at which your body can use oxygen. It is measured in litres of oxygen per minute (L/min), or (more commonly) millilitres per kilogram of body weight per minute (mL/kg/min) to account for different body sizes. All things being equal, a larger person will have a larger VO2max (L/min) because they have larger lungs, a larger heart, and more cells, which use more oxygen. This is why scientists correct for body size by dividing it by body mass ('per kg'). The best way to think of VO2max is the engine size (of your cardiovascular system): the bigger your VO2max, the more oxygen your muscles can use to create energy, and so the faster or longer you can keep exercising.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/26243014/?ref=alphabetguides.com) Your VO2max is determined partly by genetics (about half of it). But it also responds strongly to training. Things like how well your heart and blood vessels circulate oxygen-rich blood and how efficiently your muscles use the oxygen can be improved with the right type of regular exercise.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/10484570/?ref=alphabetguides.com) --- ## How VO2max changes: the physiology ### “Oxygen output” For most people, the strength and stamina of the heart are the limiting factor that determines VO2max. Exercise training can increase the amount of oxygen-rich blood your heart can pump to your muscles. Just like other muscles in your body, your heart can get bigger and stronger when regularly asked to work hard. A well-trained athlete can pump nearly twice as much blood (per beat) as an unfit person. This is why an athlete's resting heart rate is usually a lot lower, because it pumps more blood per beat even when resting. ### “Oxygen delivery” Regular exercise training stimulates the growth of new blood vessels around your muscles, meaning it can be delivered more easily. Exercise also increases the amount of blood you have, so it can carry more oxygen. So, more blood plus more blood vessels means more oxygen ends up getting delivered to your muscles. ### “Oxygen extraction” Regular exercise can also increase how much oxygen your muscles can extract (and use) from your blood. The way it does this is by increasing the number and density of small 'organelles' in the muscle called mitochondria. The more mitochondria you have, the more oxygen you can use, the more energy you make, and the longer and harder you can exercise. ## Why does VO2max decline? Half of the battle throughout life is preventing your VO2max from decreasing, and there are three main ways that it does this. - **Detraining:** As little as two weeks of inactivity can reduce how well your heart pumps blood, the amount of blood you have and how well your muscles extract oxygen. Being physically active is probably the most important thing you can do to maintain your VO2max. - **Ageing:** Unfortunately, your VO2max starts to drop as you age. You can slow the decline, but you can’t stop it entirely. That's life. Your heart, blood vessels and muscles get worn out over time and work less efficiently. - **Injury or illness:** Most long-term illnesses or serious acute ones (particularly ones that affect your heart, lungs or require bed rest) will cause quite quick and dramatic decreases in your VO2max. The good news is that when you recover from them, you can regain losses. ## Why VO2max matters for your health Beyond exercise performance, VO2max is one of the strongest predictors of overall health, heart health, metabolic health, brain health, healthy ageing, physical function, quality of life and life expectancy. In fact, some researchers argue that VO2max is the most useful measure of health, more important than many standard blood tests or resting measures for predicting long-term overall health.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/29293447/?ref=alphabetguides.com) --- ## What is a good VO2max for your age? Although VO2max naturally declines with age, those who regularly exercise will have better scores than their younger sedentary peers. The data below gives some general benchmarks for adults (in mL per kg per minute). The numbers are the average value \[bottom 10%–top 10%\].[\[4\]](https://pubmed.ncbi.nlm.nih.gov/29506981/?ref=alphabetguides.com) - 20-30 years - Men \~ 38 \[30–46\] mL/kg/min - Women \~ 34 \[25–41\] mL/kg/min - 30-40 years - Men \~ 39 \[29–48\] mL/kg/min - Women \~ 32 \[26–41\] mL/kg/min - 40-50 years - Men \~ 36 \[27–46\] mL/kg/min - Women \~ 30 \[25–38\] mL/kg/min - 50-60 years - Men \~ 32 \[24–42\] mL/kg/min - Women \~ 26 \[21–34\] mL/kg/min - Over 60 - Men \~ 28 \[21–39\] mL/kg/min - Women \~ 23 \[19–29\] mL/kg/min --- ## How to improve your VO2max _This post is for subscribers only._ ### Low-Fat Diets: A Review URL: https://www.alphabetguides.com/low-fat-diet/ Last updated: 2026-09-21T13:30:32.000Z summary - Low-fat diets limit fat to under 30% of daily calories, but most advocate eating a lot less than this. - Modest weight loss and cardiovascular health benefits are reported, particularly when saturated fats are replaced with healthier options. - Low-fat diets don't outperform other balanced diets, and very-low-fat diets risk nutritional deficiencies and low-testosterone in men. The low-fat diet limits fat intake to at least under 30% of daily calories, which is less than the typical [Western diet's](https://www.alphabetguides.com/western-diet/) fat intake of around 40%. The low-fat diet became popular in the 1980s after some studies linked dietary fat, particularly saturated fat, to cardiovascular disease. Very low-fat diets limit fat to less than 15% of total calories and are sometimes used to treat specific medical conditions.[\[1\]](https://www.ncbi.nlm.nih.gov/books/NBK553097/?ref=alphabetguides.com) [Dietary fat](https://www.alphabetguides.com/eating-fat/) has a higher calorie density (9 calories per gram) and provides more than twice the calories of carbohydrates or protein (4 calories per gram) per gram. So, reducing fat intake, in theory, allows for larger volumes of food for the same calories, which may help reduce calorie intake and body weight. Additionally, reducing saturated fat was believed to decrease [cardiovascular disease](https://www.alphabetguides.com/tag/heart-health/) risk, though this relationship has proven to be more complicated than initially thought. Low-fat diets generally emphasise eating lean proteins such as skinless poultry, fish, egg whites, and low-fat dairy products, along with fruits, vegetables, whole grains, and legumes. While limiting fatty meats, full-fat dairy, butter, oils, nuts, seeds, fried foods, and [processed items](https://www.alphabetguides.com/ultra-processed-food-diet/) high in fat. As fat intake is reduced, carbohydrates usually make up a larger proportion of the diet, making the ‘quality’ of carbohydrate intake especially important. For decades, public health guidelines have promoted low-fat diets, but modern science now focuses more on reducing specific types of fats first rather than on reducing the total amount of fat. --- ## Example foods and dishes - **Breakfast:** - Skim milk with low-fat granola and banana - Egg white omelette with mixed veg and whole wheat toast (no butter) - **Lunch:** - Whole-grain chicken breast sandwich with mustard, lettuce, and tomato - Turkey breast with steamed rice and veggies - **Snack:** - Pretzels, rice cakes - Fat-free yoghurt with fruit - **Dinner:** - Baked cod with baked potato, cottage cheese and steamed broccoli - Skinless chicken breast with whole wheat pasta and marinara sauce - **Dessert:** Angel food cake with fresh berries - **Drinks:** Orange juice, diet soda, skim milk --- ## Pros Low-fat diets show clear cardiovascular health benefits, particularly when saturated fats are replaced with [healthier unsaturated fats](https://www.alphabetguides.com/superfood-olive-oil/) or ‘complex’ (whole food, whole grain) carbohydrates. There is evidence showing that cardiovascular health risks can be reduced further when weight loss occurs, which is also reported in overweight or obese people who follow the diet.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/11126204/?ref=alphabetguides.com) When well-planned with adequate protein and healthy carbohydrates from whole grains, fruits, and vegetables, low-fat diets can provide complete nutrition (and all-round health). The emphasis on plant-based foods also naturally increases intake of dietary fibre, vitamins, minerals, and phytonutrients. The diet's accessibility and compatibility with many ‘cultural’ (carbohydrate-based) eating patterns contribute to its appeal. ## Cons Evidence for low-fat diets' superiority over other diets is mixed. Long-term studies show no consistent advantage over other [balanced diets](https://www.alphabetguides.com/fat-loss-diets/) for weight loss, with many studies demonstrating equal outcomes after 12 months.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/29466592/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/26527511/?ref=alphabetguides.com) Researchers generally report little difference in health markers for low-fat dieters (e.g., lipid profile, blood pressure, or blood sugar levels) compared to diets with moderate fat intake.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/18635428/?ref=alphabetguides.com) Very-low-fat diets (below 15% of calories) can increase the risk of nutrient deficiencies and higher intake of refined carbohydrates or sugars. Severely restricting dietary fat also likely reduces the intake of essential fats and fat-soluble vitamins (A, D, E, K) that are needed for good health. Studies also report decreased [testosterone levels](https://www.alphabetguides.com/the-testosterone-diet/) in men following very-low-fat diets, raising concerns about hormonal effects.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/26602244/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/33741447/?ref=alphabetguides.com) The diet's lower ‘satiety’ compared to higher-fat or [higher-protein diets](https://www.alphabetguides.com/high-protein-diet/) may be challenging for some people who struggle to control their appetite. Fat adds flavour to food and helps it feel satisfying, so restricting it can make meals less enjoyable. In practice, many people find low-fat diets difficult to sustain in the long term. --- ## Bottom Line Low-fat diets can support modest weight loss and cardiovascular and metabolic health benefits when thoughtfully done. However, low-fat diets are not clearly superior to other balanced diets and can *potentially* pose risks if taken to extremes. Modern evidence supports promoting fat quality over quantity, making moderate-fat diets (i.e., 15-30% total calorie intake) with healthy fat sources preferable for most people. --- ## Overall Score: **★★★☆☆** - Health Benefits: **★★★☆☆** - Nutrition: **★★★☆☆** - Weight Control: **★★★☆☆** - Ease to Follow: **★★★☆☆** - Safety Profile: **★★★☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

Your sleep schedule (i.e., when you fall asleep and wake up) is controlled by an internal body clock that can be shifted, reset, and improved with the right approaches. This article explains how to fix a disrupted sleep schedule with a practical, evidence-based plan. Staying up until 3 a.m. scrolling on your phone. Sleeping in until noon on weekends. Travelling a lot? Working late and lying awake despite being exhausted. Sound familiar? A thrown-off sleep schedule is one of the most common (and fixable) sleep problems out there. The good news: your body clock is not permanently broken. It is a biological system, and like any system, it responds predictably to the right inputs. Here’s a seven-step plan to fix your sleep schedule. ## How your body clock works — and why it gets disrupted? Your sleep-wake cycle is governed by your “circadian rhythm”. This is an internal 24-hour clock located in a tiny region of the brain (in the 'suprachiasmatic nucleus'). This clock controls when you feel sleepy, when you wake, when your body temperature peaks and dips, and when hormones like [cortisol](https://www.alphabetguides.com/what-is-cortisol/) and melatonin are released. When this clock is out of sync with night and day or your desired sleep times, you get what researchers call circadian 'misalignment'. The result is that familiar “wired-but-tired” feeling: your brain is exhausted, but your body doesn't get the “go to sleep now” signal at the right time. The most powerful external cue for resetting this clock is light. [Nutrition](https://www.alphabetguides.com/eat-for-better-sleep/), meal timing, exercise, and social schedules also play a role, but light is the dominant signal. --- ## The 7-step plan to fix your sleep schedule ### Step #1: Set a fixed wake time and stick to it Start by working backwards from when you need to wake up for work. Most adults need 7-9 hours a night. Choose a realistic bedtime and wake time that you can maintain seven days a week — yes, that includes weekends as well. Write them down. This is your target schedule. ### Step #2: Use morning light — your most powerful reset tool Bright light in the morning is the single most effective tool for advancing your circadian clock (shifting it earlier). Morning light exposure suppresses melatonin, improves your daytime alertness, and helps you to sleep earlier in the evening.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/31534436/?ref=alphabetguides.com) **What to do:** Get outside within half an hour after waking, sooner the better. Aim for 20 to 30 minutes of natural light, even on overcast days. Outdoor light is substantially brighter than indoor lighting, even on grey mornings. ### Step #3: Advance your bedtime gradually Don't try to fix a three-hour misalignment in one night. Instead, move your bedtime earlier by half an hour every two to three days until you reach your target. This gradual approach aligns with the pace at which the circadian clock can realistically shift — roughly one to two hours per day under optimal conditions. ### Step #4: Protect your wake time _This post is for subscribers only._ ### How To Sleep Better URL: https://www.alphabetguides.com/how-to-sleep-better/ Last updated: 2026-09-02T17:04:39.000Z summary - Morning bright light, within 2 hours of waking, shifts your circadian clock, making it easier to fall asleep earlier at night. - Room light before bed can suppress melatonin ("sleep hormone") by about 50% and delay getting to sleep by around 90 minutes. - The ideal bedroom temperature is 19–21°C (66–70°F); being too warm reduces time spent in deep sleep stages. Poor sleep affects millions of people worldwide. It causes fatigue, poor concentration, mood problems, and [increases health risks](https://www.alphabetguides.com/sleep-and-health/). In this article, we cover ways to improve your sleep quality, from light exposure and your bedroom environment to timing your exercise session. Struggling to fall asleep, waking frequently during the night, or feeling exhausted despite spending eight hours in bed? Wired but Tired! You're not alone — and the solution often lies in simple, effective evidence-based changes to your daily habits and sleep environment. No $5000 mattress, fancy tech, or overpriced supplements required. ## How much sleep do you actually need? Most adults need 7 to 9 hours of sleep per night. Teenagers need more (8 to 10 hours), while older adults often do well with 7 to 8 hours. It’s not all about how long you sleep for (your “sleep duration”) — other things matter just as much. But consistently getting less than 7 hours increases your risk for obesity, diabetes, heart disease, stroke, and mental health problems. ## Signs you're not sleeping well Poor sleep isn't just about quantity—quality matters enormously. Warning signs include: - Regularly taking more than 30 minutes to fall asleep - Waking up multiple times during the night - Tossing and turning a lot at night - Lying awake for long periods during the night - Waking up too early and being unable to fall back asleep - Feeling unrefreshed despite adequate time in bed - Sleepiness, fatigue, or difficulty concentrating during the day - Relying on caffeine to stay alert during the day - Mood changes, irritability, or feeling more stressed ## Why sleep matters Quality sleep is essential for physical health, brain function, and social and emotional well-being. While you're sleeping, your body repairs your tissues, consolidates memories, regulates hormones, and clears metabolic waste from the brain. Sleeping poorly for a long period of time increases inflammation, weakens your immune system, impairs cognitive function, and raises the risk of serious health conditions. It can also be a signal that something isn’t quite right in your life, or in your body. ## Common causes of sleep problems Sleep issues stem from various sources: stress and anxiety, irregular sleep schedules, poor sleep environment (too bright, noisy, warm), excessive screen time before bed, caffeine or alcohol consumption, lack of physical activity, certain medications, and underlying health conditions. If sleep issues persist despite trying [evidence-based strategies](https://www.alphabetguides.com/fix-your-sleep-schedule/), talk to a healthcare professional. You may well have an underlying sleep disorder (e.g., sleep apnea, insomnia, restless leg syndrome, or narcolepsy), which needs specialist help. Warning signs requiring medical evaluation include loud snoring with breathing pauses, gasping or choking during sleep, severe daytime sleepiness, or sleep problems that last more than a month. ## Ways to get better sleep ### #1\. Light exposure Light is probably the most powerful regulator of your sleep-wake cycle. Bright light exposure in the morning and avoiding bright or blue light in the evening helps shift 'circadian timing' and improves sleep, especially in people with delayed sleep patterns.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/31108433/?ref=alphabetguides.com) **Morning bright light.** Get 30 to 60 minutes of bright light exposure within 2 hours of waking, ideally outdoors. Morning light advances your 'circadian clock', making it easier to fall asleep at night and wake up refreshed. Even when it’s cloudy, outdoor light is still brighter than indoor lighting. No fancy light clocks required, just get outdoors, first thing in the morning. **Evening lights.** Dim lights 2 to 3 hours before bed. Blue light from screens suppresses melatonin production more than other wavelengths, delaying sleep onset and reducing sleep quality.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/21164152/?ref=alphabetguides.com) **Use blue light filters** on devices after sunset, or better yet, avoid screens entirely in the hour before bed. Red and amber light wavelengths (660-870 nm) have minimal impact on melatonin. If you really need light at night, you can consider using red-wavelength light bulbs. **Complete darkness for sleep.** Your bedroom should be dark enough that you *can't* see your hand in front of your face. Use blackout curtains or an eye mask to block all light sources, including street lights and vampire lights on your electronic device indicators. ### #2\. Mind-body exercise Mind-body practices like yoga and tai chi improve sleep in a few ways; they reduce stress, promote relaxation, and help regulate your nervous system activity. Yoga improves sleep quality, and other mind-body activities are also shown to improve sleep quality, reduce insomnia and reduce tiredness throughout the day. Here's what to do.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/32357858/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/34163383/?ref=alphabetguides.com) - Practice gentle yoga or tai chi 2 to 4 times weekly - Evening sessions work well, but avoid vigorous practice right before bed - Incorporate breathing exercises (see relaxation section below) - Even just 20 minutes provides benefits These mind-body practices are shown to [reduce cortisol](https://www.alphabetguides.com/ways-to-decrease-cortisol/) levels and activate the parasympathetic nervous system (your "rest and digest" system), creating physiological conditions that are needed for good sleep. ### #3\. Time your exercise Regular physical activity noticeably improves sleep, but the timing of the exercise matters (how close to bedtime it is). Both aerobic and [resistance training](https://www.alphabetguides.com/minimalist-muscle-growth/) improve sleep quality and reduce insomnia in adults. Research also shows that exercise enhances slow-wave (deep) sleep quality even when your total sleep time doesn't change. How to exercise for sleep:[\[5\]](https://pubmed.ncbi.nlm.nih.gov/33627708/?ref=alphabetguides.com) 1. Aim for at least 150 minutes of [moderate activity](https://www.alphabetguides.com/what-are-training-zones/) or 75 minutes of vigorous activity weekly 2. Morning or afternoon exercise tends to promote better sleep than late evening workouts 3. Avoid vigorous exercise 2 to 3 hours before bed, as it increases body temperature and arousal. 4. Light stretching, gentle yoga or tai chi in the evening is fine and may actually help 5. Even just a 10-minute daily [walk](https://www.alphabetguides.com/why-walking-beats-running/) provides sleep benefits [Exercise reduces anxiety,](https://www.alphabetguides.com/exercise-and-anxiety/) regulates circadian rhythms, increases “adenosine” (a sleep-promoting brain chemical), and helps regulate your body temperature, which all support better sleep. The improvement in slow-wave sleep quality is particularly valuable, as this is the most physically restorative sleep stage. ### #4\. Improve your sleep environment _This post is for subscribers only._ ### Zone Diet: A Review URL: https://www.alphabetguides.com/zone-diet/ Last updated: 2026-09-22T10:07:39.000Z summary - The zone diet is built around a rigid 40:30:30 macronutrient ratio at every meal, aimed at controlling insulin and glucagon release. - The diet produces modest short-term weight loss and is nutritionally adequate compared to other (more restrictive) diets. - There is limited evidence showing that the diet leads to superior outcomes over simpler calorie-restriction or other healthy diets. The Zone Diet is a commercial diet developed in the 1990s by Dr Barry Sears (a biochemist). The diet is based on the premise that health can be controlled through precise ‘macronutrient’ ratios by keeping your inflammation and body weight within healthy levels. The diet is based on maintaining a ‘zone’ that maintains optimal “hormonal balance”. Specifically, two hormones: insulin and glucagon, which proponents of the diet argue are key drivers of most diseases. The defining feature of the diet is a rigid macronutrient distribution. The diet requires that every meal and snack follow a 40:30:30 ratio: 40% of calories from carbohydrates, 30% from protein, and 30% from fat. This balance must be maintained at each eating occasion, not just your daily totals. The diet follows a structured eating pattern of three meals and two snacks a day, which are to be eaten at specific times of the day to keep your hormones stable.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/18370674/?ref=alphabetguides.com) Low-glycemic carbohydrates (i.e., ones that don't raise blood sugar a lot) are preferred, which include most vegetables, some fruits (berries, apples, pears), and limited whole grains. It restricts or eliminates high-glycemic carbs (i.e., those that raise blood sugar a lot) like potatoes, bread, pasta, rice, and most [processed carbohydrates](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/). Protein sources include lean meats, poultry, fish, egg whites, low-fat dairy, and plant proteins. Fat recommendations favour the healthier monounsaturated fats like [olive oil](https://www.alphabetguides.com/superfood-olive-oil/), avocados, and nuts while limiting saturated fats. To make the counting easier, the diet uses a ‘block’ system for portion control. Each block contains specific amounts of protein, carbohydrate, and fat to maintain the ratios. Typical daily intake ranges from 11–14 blocks for women and 14-17 for men, equating to approximately 1,200-2,000 calories a day.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/18370674/?ref=alphabetguides.com) --- ## Example foods and dishes - **Breakfast:** - Black coffee or tea (during fasting window, no food) - Water with electrolytes (during fasting window, no food) - **Lunch:** - Large mixed salad with grilled chicken, avocado, nuts, olive oil (breaking fast) - Burrito bowl with rice, beans, meat, cheese, guacamole (first meal) - **Snack:** - Mixed nuts and an apple (during eating window) - Cheese and crackers (during eating window) - **Dinner:** - Salmon with roasted veg and sweet potato - Pasta with meat sauce, salad leaves, and garlic bread - **Dessert:** Ice cream or cookies (during eating window) - **Drinks:** Black coffee, tea, sparkling water --- ## Pros The Zone Diet produces modest short-term [weight loss](https://www.alphabetguides.com/tag/fat-loss/) comparable to other calorie-restricted diets. This seems to occur through reduced overall calorie intake rather than the specific macronutrient ratios, as studies show similar weight loss following other diets with similar energy intakes.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/18370674/?ref=alphabetguides.com) Research shows the diet provides sufficient micronutrients with a low risk of any major deficiencies. The diet achieves a good nutritional balance, which is better than more restrictive diets, as it incorporates vegetables, fruits, lean proteins, and healthy fats in reasonable amounts. The emphasis on low-glycemic carbohydrates, increased intake of lean proteins, and healthy fats represents an improvement over typical [Western diets](https://www.alphabetguides.com/western-diet/). The structured approach of the diet also eliminates many processed foods, added sugars, and refined carbohydrates. This will probably improve diet quality for people who already have poor dietary habits.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/12569110/?ref=alphabetguides.com) ## Cons Despite three decades since its introduction, high-quality long-term studies demonstrating superior health outcomes (over and above other diets) are limited. The hormone-driven mechanism underlying the diet's health benefits lacks any direct supporting evidence, and whilst short-term weight loss is reported, evidence for sustained weight maintenance is limited. The diet shows no clear advantage over other (simpler) [calorie-restriction](https://www.alphabetguides.com/hara-hachi-bu-an-ancient/) diets.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/12569110/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/15100495/?ref=alphabetguides.com) The rigid 40:30:30 ratio at every meal creates complexity, which some people find difficult to maintain. Calculating blocks, measuring portions, and ensuring precise macronutrient balance at each meal and snack requires significant planning, calculation, and dedication.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/17341711/?ref=alphabetguides.com) The rigid complexity likely reduces long-term adherence to the diet. Simpler approaches focusing on food quality rather than precise counting likely achieve similar (or better) results, with greater flexibility and sustainability. --- ## Bottom Line The Zone Diet’s nutritionally adequate, moderately restrictive approach produces short-term weight loss through calorie restriction. While safe and reasonably balanced, it lacks strong evidence demonstrating superiority over other, simpler diets, and it presents some practical challenges. --- ### Overall Score: _This post is for subscribers only._ ### What to Eat for Better Sleep URL: https://www.alphabetguides.com/eat-for-better-sleep/ Last updated: 2026-09-15T14:52:59.000Z summary - Even a small coffee (around 100mg caffeine) must be consumed at least 9 hours before bed; a large one requires at least 13 hours. - High-fibre diets promote deeper slow-wave sleep; diets high in saturated fat and sugar consistently produce lighter, more fragmented sleep. - Even one beer or a small glass of wine measurably impairs sleep quality — including REM suppression — throughout the night. Sleep is influenced by what you eat and drink, yet many people overlook the impact of their diet. This article looks at what foods and drinks are good and what to avoid for good sleep. We’ll also cover the science behind how specific nutrients, supplements, and dietary patterns affect your sleep. Your diet plays a more important role in your sleep quality than you may think. The foods you eat throughout the day (and especially in the evening) influence your ability to fall asleep, stay asleep, and [sleep well](https://www.alphabetguides.com/how-to-sleep-better/). ## What foods help you sleep better? ### The Mediterranean diet Mediterranean-style eating patterns are strongly associated with better sleep quality and quantity. It’s rich in vegetables, fruits, whole grains, legumes, nuts, olive oil, and fish, which support sleep by reducing inflammation, improving gut health, and providing enough of the essential “sleep-promoting” nutrients.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/35889954/?ref=alphabetguides.com) The Mediterranean diet isn't about individual "superfoods" but a “holistic” approach that is based on eating minimally processed, nutrient-dense foods with plenty of fibre and healthy fats (usually from olive oil). ### Tryptophan-rich foods Tryptophan is an essential amino acid your body uses to produce serotonin and melatonin, two "neurotransmitters" that are needed to regulate your sleep-wake cycles. Foods rich in tryptophan include dairy products (like milk, cheese, yoghurt), poultry (turkey, chicken), fish, eggs, soy products, nuts, and seeds. Tryptophan supplementation at doses exceeding one gram per day can help improve sleep quality. That said, food sources provide more modest amounts, but regular consumption of tryptophan-rich foods can still offer benefits.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/33942088/?ref=alphabetguides.com) A specific dairy protein called 'alpha-lactalbumin' (found in dairy products) has been shown to increase tryptophan when consumed in the evening, and it goes on to improve alertness and attention when you wake up. 💡 ****Tip #1:** Combine tryptophan-rich protein with complex carbohydrates in your evening meal, as carbohydrates facilitate tryptophan's transport to the brain, where it helps you sleep. ### Melatonin-rich foods Several foods naturally contain melatonin or other substances that increase melatonin. Melatonin-rich tart cherry juice has been shown to improve both sleep quality and quantity. Other melatonin-rich food options are milk, kiwi, and some cereals. Several studies have shown that eating these foods in the evening, around an hour before bed, can improve sleep.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/22038497/?ref=alphabetguides.com) Melatonin supplements (typically 0.5 to 3 mg taken 30 to 60 minutes before bed) can also improve sleep quality, particularly in adults with respiratory conditions, metabolic diseases, and sleep disorders. However, the benefits of melatonin supplementation on sleep in healthy people are less certain.[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4273450/?ref=alphabetguides.com) ### Fatty fish, omega-3s and vitamin D Salmon, mackerel, trout, and other fatty fish contain high levels of omega-3 fatty acids and vitamin D, which influence sleep quality by increasing serotonin production and reducing inflammation. Studies show that regular consumption of [oily fish](https://www.alphabetguides.com/superfood-oily-fish/) is associated with better sleep quality and daytime functioning. While evidence for omega-3 supplementation shows mixed results by itself, including fatty fish in your diet 2 to 3 times per week provides these nutrients that are good for your sleep and for your overall health. ### High-fibre food High-fibre diets rich in fruits, vegetables, and whole grains are associated with deeper “slow-wave” sleep (the most important stage of sleep). Higher intake of saturated fat and sugar predicts lighter, more fragmented sleep; things not usually found in high-fibre foods. Eating fibre-rich foods can help you sleep by controlling your blood sugar levels overnight and promoting a healthy gut microbiome that helps you sleep.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/35063665/?ref=alphabetguides.com) To improve your fibre intake: start your day with porridge or whole-grain cereals with fruit. Eat a large portion of salad and vegetables with your dinner. Choose whole grains over refined carbohydrates. Add [beans and lentils](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/) to soups, stews, and broths. Snack on fruit or vegetable sticks with hummus. ### Zinc-rich foods Zinc-rich seafood (especially oysters) is shown to help you get to sleep faster and sleep better. The beneficial effects of zinc may relate to its role in sleep regulation and the 'neurotransmitters' in your brain, like serotonin, melatonin and GABA.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/28019085/?ref=alphabetguides.com) Good sources of dietary zinc include: oysters and other shellfish, [red meat](https://www.alphabetguides.com/carnivore-diet/), beans and pulses, pumpkin seeds, cashew nuts and almonds. The sleep improvements from zinc appear most pronounced when addressing deficiency or inadequate intake (which is surprisingly common). ### Other vitamins and minerals for sleep Multiple vitamins and minerals are important for sleep. So deficiencies in these nutrients are commonly found in people reporting poor sleep. These include: - Magnesium, which is involved in producing melatonin and supports GABA (helps you relax). Good sources include whole grains, nuts, seeds, legumes, and [leafy greens](https://www.alphabetguides.com/superfood-leafy-greens/). - B vitamins (particularly B1 and folate), vitamin D, vitamin C, and minerals like selenium, calcium, iron, and phosphorus have all been associated with better sleep. People who sleep poorly generally have lower intakes of these micronutrients. 💡 ****Tip #2:** Rather than worrying about getting dozens of individual nutrients at a time, it is easier to focus on eating a varied, nutrient-dense diet to ensure adequate micronutrient intake supporting sleep. ### Eat breakfast for better sleep Regularly eating breakfast is associated with better sleep. Breakfast eaters have better control of their appetite throughout the day and [better sleep](https://www.alphabetguides.com/how-to-sleep-better/) quality compared to those who routinely skip their morning meal.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/30402594/?ref=alphabetguides.com) The sleep benefits of eating breakfast regularly are thought to be related to maintaining consistent circadian eating patterns and avoiding the metabolic disruptions that come with prolonged morning fasting. ## What to avoid for better sleep ### Caffeine Caffeine is probably the most powerful dietary disruptor of sleep; it can reduce total sleep time by approximately 45 minutes, it worsens how well you sleep and it makes it more difficult to get to sleep. You don’t have to give up caffeine entirely, but timing your intake is critical if you want to improve your sleep. Here's what the research recommends:[\[8\]](https://pubmed.ncbi.nlm.nih.gov/36870101/?ref=alphabetguides.com) A small coffee (\~100 mg caffeine) should be consumed at least 9 hours before bedtime. A stronger or larger coffee or pre-workout supplement (over 200 mg) requires at least 13 hours before bed to avoid sleep disruption. This means if you aim to sleep at 10 PM, you should avoid caffeine after 1 PM for a small coffee, or after 9 AM for stronger sources of caffeine. Caffeine lurks in obvious places (like coffee and energy drinks), but it is also in tea (especially black and green), many sodas, chocolate, some medications, and pre-workout supplements. Read the labels and get your timing right if you want to optimise your sleep. ### Alcohol While alcohol may make you feel sleepy initially and may help you fall asleep faster, it disrupts sleep quality throughout the night. Alcohol suppresses 'REM sleep' (the stage associated with memory and emotional processing), fragments your sleep, and causes more awakenings in the second half of the night. Even low to moderate alcohol intake (e.g., 1 beer or a small glass of wine) affects your sleep quality. For restful, restorative sleep, reduce alcohol consumption pretty much to zero, and avoid drinking within 3 hours of bed. ### Nicotine Nicotine from smoking, vaping, nicotine pouches, or gum also reduces sleep quality. Smokers and nicotine users commonly have more difficulty getting to sleep, waking up more often, and getting less restorative sleep. Like caffeine, the stimulant effects of nicotine interfere with your ability to fall asleep and maintain deep sleep stages. If you use nicotine products, avoiding them for several hours before bedtime can help minimise sleep disruption, though avoiding them entirely and reducing the amount you use them will provide the greatest benefits to your sleep. ### Cannabis and THC Despite many people using cannabis to help with sleep, researchers group it with alcohol, nicotine, and caffeine as substances that reduce sleep quality. While the evidence isn’t as conclusive, habitual cannabis use is associated with poorer sleep. However, some people with health conditions who severely struggle with their sleep (e.g., sleep disorders, chronic pain, PTSD, multiple sclerosis), have reported positive effects of cannabis use on sleep. ### Ultra-processed foods, sugar and saturated Fat Diets high in saturated fat, added sugars, and ultra-processed foods are linked with lighter, less restorative sleep and insomnia. People with poor sleep consume more [ultra-processed foods](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/) compared to good sleepers.[\[9\]](https://pubmed.ncbi.nlm.nih.gov/33549913/?ref=alphabetguides.com) These foods may impair sleep by destabilising blood sugar levels, increasing inflammation, and worsening your gut microbiome, body weight and hormonal health. Skip the soft drinks, energy drinks, packaged foods, fast food, instant and microwave foods, sweets and confectionery, or keep it to a minimum. ### Late-night eating Eating large meals close to bedtime or consuming high-fat, high-carbohydrate snacks in the evening disrupts your “nighttime metabolism”. It’s linked to poorer health and sleep outcomes. Late-night eating can interfere with the body's natural “circadian rhythm” and the processes that should occur just before and during sleep.[\[10\]](https://pubmed.ncbi.nlm.nih.gov/32525525/?ref=alphabetguides.com) People who eat most of their calories later in the day have a higher risk of obesity and metabolic diseases. The evidence suggests “front-loading” calories earlier in the day is better for your health and sleep quality. The high-salt intake from processed foods is also associated with poorer sleep quality by affecting blood pressure and fluid balance, which disrupt comfort when in bed. ## What supplements are good (or not so good) for sleep - **Ashwagandha extract** has demonstrated small but measurable improvements in both sleep quantity and quality in adults with insomnia or poor baseline sleep. While the effects are modest, it is one of the better-studied herbal supplements for sleep.[\[11\]](https://pubmed.ncbi.nlm.nih.gov/34559859/?ref=alphabetguides.com) - [**Creatine**](https://www.alphabetguides.com/creatine-muscle/)**:** Although we’ve heard of anecdotal reports, we’re not aware of any high-quality research showing that creatine affects sleep in any profound way. - **Chamomile & Herbal Teas:** While they may not robustly promote sleep, caffeine-free herbal teas serve as a reasonable, cheap, safe bedtime drink that can be part of a relaxing routine. They're definitely preferable to caffeinated drinks. ## Putting it all into practice ### Throughout the day: _This post is for subscribers only._ ### Should You Exercise While Fasting? URL: https://www.alphabetguides.com/should-you-exercise-fasted/ Last updated: 2026-09-22T09:51:16.000Z summary - Fasted exercise burns more fat both during and after training and can improve metabolic health beyond what fed-state exercise achieves alone. - Pre-exercise feeding improves performance for sessions longer than 60 minutes. But moderate-intensity sessions are not affected. - High-intensity intervals, competition training, and sessions over 90 minutes are better performed in a fed state. 'Fasted exercise' is a practice that has gained popularity with people who follow [intermittent fasting](https://www.alphabetguides.com/types-of-intermittent-fasts/) or time-restricted eating patterns regularly. This article explains the science behind training while fasting, examining the potential benefits for fat loss, health, and balancing the performance trade-offs and safety concerns. There have been heated debates about exercising while fasting. Advocates claim it's the secret to accelerated fat loss and an optimal metabolic state. Critics say it impairs performance and [muscle growth](https://www.alphabetguides.com/back-to-basics-a-checklist-for-muscle-growth/). So what’s the truth? The answer is not straightforward. Fasted exercise can offer benefits for certain goals and certain people — but it also has some trade-offs. ## What happens in your body when you exercise fasted? When you haven't eaten for several hours, your body enters a [fasted state](https://www.alphabetguides.com/the-fasting-timeline-what-happens-to-your-body-hour-by-hour/): your insulin levels drop, growth hormone rises, and your body increasingly relies on stored energy (primarily fat and glycogen) rather than nutrients from recently consumed food. Your [muscles](https://www.alphabetguides.com/tag/muscle/) burn proportionally more fat and less carbohydrate compared to exercising after eating. This shift toward burning more fat continues, not just during exercise, but for hours afterwards as well. Regular fasted training can enhance 'insulin sensitivity' (your cells' responsiveness to insulin) and improve your body’s ability to utilise fuel (both carbohydrates and fats) for energy.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/27609363/?ref=alphabetguides.com) ## Does fasted exercise burn more fat? Yes, exercising while fasted increases 'lipolysis' (breakdown of your fat stores) and 'fat oxidation' (burning fat) both during and after your workout. So, combining fasting with exercise can help with [weight loss and fat loss](https://www.alphabetguides.com/tag/fat-loss/). However, just increasing the amount of fat you burn during exercise doesn't necessarily translate to dramatically greater fat loss over time. If you’re specifically trying to reduce body fat, especially when combined with an overall calorie-controlled diet, fasted exercise can be a useful tool. ## What are the health benefits of fasted exercise beyond fat loss? Beyond fat loss, fasted exercise potentially offers health benefits that make it attractive even for people who don't want to lose weight. Research in people with 'non-alcoholic fatty liver disease' found that combining alternate-day fasting with aerobic exercise significantly improved liver fat, body weight, and insulin sensitivity.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/36549296/?ref=alphabetguides.com) The improvement in insulin sensitivity (meaning your body can handle your blood sugar levels better) will also reduce your risk of metabolic diseases (like obesity, fatty liver disease and diabetes), probably beyond what you'd achieve from fed-state exercise or fasting alone. ## Does fasted exercise hurt performance? So while fasted exercise offers metabolic health and body composition benefits, it may come with a performance trade-off. Research shows that eating before exercise improves exercise performance for sessions that are longer than an hour. For shorter, [moderate-intensity](https://www.alphabetguides.com/what-are-training-zones/) aerobic exercise sessions, the performance differences are not usually noticeable.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/29315892/?ref=alphabetguides.com) Fasted high-intensity exercise may be problematic, as your body relies on carbohydrates for this sort of exercise. So, starting sessions with depleted carbohydrate stores may impair your performance in these types of exercise. Examples include high-intensity intervals, tempo training, and hard weightlifting sessions. However, some studies show that fasted low- to moderate-intensity training can improve how efficiently you use energy (and thus potentially your exercise performance). But this still means that eating a few hours before exercise will produce better results for competitions and peak performance. It’s a training tool to improve performance — not a performance-enhancing tool in itself.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/21051570/?ref=alphabetguides.com) ## Which exercises work best in a fasted state? Not all exercise is created equal when it comes to fasted training. The research suggests clear patterns about which activities work well and which don't. #### What Works - Steady-state aerobic exercise, low to moderate intensity (e.g., [walking](https://www.alphabetguides.com/why-walking-beats-running/), light jogging, cycling, swimming). - Moderate-intensity [resistance training](https://www.alphabetguides.com/minimalist-muscle-growth/) or aerobic exercise. - Yoga, tai chi, and other mind-body practices. - Short-duration workouts (under 60 minutes). #### What Doesn't Work - High-intensity interval training or high-volume, high-intensity strength or power training. - Exercise training requires peak cognitive function or coordination. - Competition or performance-focused training sessions. - Long-duration endurance sessions (over 90 minutes). Match your exercise intensity to your 'metabolic state' (fasted or fed). Moderate intensity — where you're working but can still hold a conversation — tends to be the sweet spot. At this intensity, your body can effectively use fat for fuel without requiring large amounts of quick-burning carbohydrates. ## How to exercise fasted: practical tips for getting started If you decide to try fasted exercise, these strategies can help you do it safely and effectively: _This post is for subscribers only._ ### How to Deload: 10 Things You Should & Shouldn’t Do URL: https://www.alphabetguides.com/how-to-deload/ Last updated: 2026-09-16T09:41:48.000Z summary - Reducing training volume by 30–50% is the most effective deload. Keeping frequency and exercise selection the same is also advised. - Reduce effort to approximately 6 out of 10, leaving 4–6 reps in reserve, using around 20% lighter weights than normal. - Avoid complete rest, new exercises, and high-rep sets with very light loads — all three undermine the purpose of a deload. A deload is a short period of reduced training stress designed to clear fatigue and restore performance. But how you structure it will determine how effective it actually is. So if you’re experiencing fatigue, your training is getting difficult, and your performance is flagging, you may [decide to deload](https://www.alphabetguides.com/deload/) — and the next question is how to do it. A poorly executed deload can actually leave you worse off than you were before, and fail to provide any real benefits. The good news is that the principles of deload are (relatively) straightforward, and the evidence offers some clear guidance on both what works and what to avoid. ## 1\. Meaningfully reduce your volume The single most important change during a deload is pulling back on training volume. This means reducing the total number of sets or reps performed. A reasonable starting point is to reduce your volume by 30-50% compared to your normal training week.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/36619355/?ref=alphabetguides.com) So if you normally do 10 working sets for your lower body a week, drop it to 5\. You can also reduce the number of reps per set (while lifting the same weight), or reduce the load and keep the number of reps and sets the same. The goal should be to keep the movement without creating any noticeable fatigue. ## 2\. Keep your training frequency the same Most coaches like to keep the frequency of training the same during a deload, even while reducing the volume and effort. This is done for two reasons. Firstly, it maintains the frequency at which you practice the movement ‘skill’, whether it is squatting or running; skipping all forms of movement for a long period of time may affect the technical execution of it. Second, maintaining frequency keeps your training rhythm and momentum going, so when you return to ‘full’ training, it feels like a normal progression rather than a massive step up.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/39446750/?ref=alphabetguides.com) If you normally train four days a week, train four days during your deload — just do considerably less in each session. If you are training six days a week, you probably have room to reduce the frequency by one or two sessions a week if you like. ## 3\. Reduce effort — leave more in the tank During normal training, you should be working close to failure on most ‘sets’, maybe leaving 1-3 reps in reserve (9 out of 10 effort). However, during a deload, that ‘buffer’ should widen. Aim to stop four to six reps short of failure (6 out of 10 effort), using loads that feel manageable rather than challenging. This means using lighter weights than normal. A modest reduction of 20% on most exercises is a good place to start, but you can reduce it further if you’re particularly fatigued. The point is not to see how much you can do with reduced volume; it is to keep the muscles and joints moving without adding any extra fatigue. ## 4\. Use the week to address weak points and recovery methods A deload week is a good opportunity to do the maintenance work that often gets squeezed out of normal training weeks. Light mobility work, foam rolling, and low-intensity [active recovery](https://www.alphabetguides.com/rest-and-body-composition/) (such as walking, swimming, or easy cycling) can support recovery without adding meaningful fatigue. Some athletes use deload weeks to include a small amount of work targeting areas they normally neglect (like an old rotator cuff injury or hip mobility work). While your training load is lower than normal, and you may be about to start a new phase or period of your programme, the deload week may be a good opportunity to take a look at optimising your [sleep ](https://www.alphabetguides.com/tag/sleep/)or [nutrition](https://www.alphabetguides.com/tag/nutrition/). ## 5\. Plan your deload strategically (if you can) _This post is for subscribers only._ ### Exercise for Depression: Does it Work? URL: https://www.alphabetguides.com/exercise-for-depression/ Last updated: 2026-09-22T09:51:36.000Z summary - Exercise produces antidepressant effects comparable to medication and psychotherapy for people with mild to moderate depression. - Three sessions per week of 30–60 minutes at moderate-to-vigorous intensity, for at least 4 weeks, is a good target to start with. - Any type of exercise works (e.g., aerobic, resistance, or yoga) — but the most effective is whichever you will do consistently. Depression is a common mental health condition affecting over 300 million people worldwide. It is characterised by unrelenting sadness, apathy, and low energy that interfere with daily life. This article explains how, how much and what type of exercise can be used to treat depression, along with practical strategies for exercising when depression makes it feel out of reach. If you're living with depression, you've likely heard that exercise can help. Perhaps your doctor mentioned it, or well-meaning friends suggested you "[go for a walk](https://www.alphabetguides.com/why-walking-beats-running/)". But when you're struggling to get out of bed, the idea of exercising can feel overwhelming (or even insulting). The research actually shows that exercise isn't a cure-all, and it's not always easy — but it’s one of the most effective and proven treatments. The evidence is so strong that exercise now rivals more traditional treatments, like medication and talking therapies. ## What the research shows: exercise vs antidepressants The scientific evidence for exercise as a depression treatment is robust. A large study on over 14,000 people found that exercise produces moderate antidepressant effects, with walking, jogging, yoga, strength training, and mixed aerobic exercise all showing meaningful benefits.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/36731907/?ref=alphabetguides.com) Another study focusing specifically on adults with major depression found a large antidepressant effect of exercise. The effect was large enough that the 'number needed to treat' was approximately two. This means that for every two people who exercise for depression, one experienced significant symptom relief (that's a success rate for any comparable treatment).[\[2\]](https://pubmed.ncbi.nlm.nih.gov/36796860/?ref=alphabetguides.com) Multiple studies show that exercise performs similarly to antidepressant medications and psychotherapy. When it’s used alongside these treatments, exercise can also enhance their effectiveness, providing complementary benefits. These benefits also extend across the lifespan. Physical activity has been shown to help depressive symptoms in healthy people, people with other health issues and diseases, and those with diagnosed mental health conditions. It may also help alleviate depressive symptoms in children and adolescents.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/38787545/?ref=alphabetguides.com) ## What is the best exercise for depression? The good news is that multiple forms of physical activity effectively treat depression, giving you flexibility to choose activities that match your personal preferences and ability. Aerobic exercise like walking, [jogging,](https://www.alphabetguides.com/why-running-is-better-than-walking/) swimming, or cycling has been studied most extensively and consistently shows strong antidepressant effects. The beauty of aerobic exercise is its accessibility — you can start with gentle walking and gradually increase intensity as you get fitter. [Strength training](https://www.alphabetguides.com/back-to-basics-a-checklist-for-muscle-growth/) with weights or resistance bands also produces meaningful improvements in depressive symptoms. Some people find that the measurable progress of getting stronger provides a sense of accomplishment that's particularly valuable when depression makes everything feel hopeless. Low-intensity 'mind-body' exercise like yoga, tai chi, and qigong also has antidepressant effects. These activities combine movement with breath awareness and mindfulness, addressing depression in multiple ways at the same time. There doesn’t appear to be a single “best” exercise for depression — the most effective type of exercise is the one you'll actually do consistently. ## How much exercise do you need for depression? A typical effective program includes exercise 3 times per week for 30 to 60 minutes per session, maintained for at least 4 to 16 weeks. This doesn't mean you need to immediately commit to hour-long workouts — many studies show benefits from starting smaller and building up your exercise capacity gradually. Moderate to vigorous [intensity](https://www.alphabetguides.com/what-are-training-zones/) tends to produce the strongest antidepressant effects. Moderate intensity means you're breathing harder than normal but can still hold a conversation. Vigorous means you're breathing hard enough that talking becomes difficult. That said, when you're depressed, even light physical activity is better than none. If 30 minutes feels impossible, start with 10\. If three times per week sounds overwhelming, start with one. Research shows that even modest amounts of regular activity provide mental health benefits. Supervised group-based programmes also show stronger effects and better adherence than unsupervised solo workouts. The structure, accountability, and social connection of group exercise may help amplify the antidepressant benefits of exercise. ## How long does it take for exercise to help with depression? Most research studies show meaningful improvements after 4 to 8 weeks of regular exercise. Some people notice benefits sooner (within just a few weeks), while others require longer to see noticeable effects. The timeline varies based on the severity of your depression, the type and intensity of exercise you're doing, how consistently you maintain the routine, and whether you're combining exercise with other treatments like therapy or medication. Each workout you do will provide some immediate mood benefits; you may notice you feel slightly better for a few hours after exercise. However, the more powerful, lasting change is built over weeks and months of consistent training.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/32491278/?ref=alphabetguides.com) This gradual timeline can feel frustrating when you're struggling, but it's actually similar to how antidepressant medications or psychotherapy work. These treatments also require 4 to 8 weeks to reach full effectiveness. ## How exercise changes the depressed brain ### Brain changes Exercise changes [the way your brain works](https://www.alphabetguides.com/tag/brain-health/). Regular physical activity increases production of 'neurotrophic factors' (things that support the growth, survival, and connections of, and between, your brain cells). Depression is associated with low amounts of these, so exercise may directly counteract it. Exercise also helps maintain the volume of parts of the brain that support better mood, brain function, and controlling emotions. These areas are often shrunk in people with depression5. Exercise also helps keep brain chemicals under control (like [cortisol](https://www.alphabetguides.com/what-is-cortisol/), cytokines, dopamine, serotonin, and norepinephrine). This means you can handle stress and changes in mood a lot better. ### Psychological changes Beyond biology, exercise provides some psychological benefits. It builds your 'self-efficacy' (i.e., your confidence to do things and handle challenges). Depression can make things feel impossible, but the process of completing a workout can begin rebuilding your sense of achievement. Exercise also enhances coping skills and emotional control. The elevated heart rate, heavier breathing, and muscle fatigue share similarities with anxiety and distress. So regularly experiencing these sensations in a safe, controlled environment can improve your tolerance for discomfort and for getting triggered by it. For many people, exercise programmes provide structure to days that depression has emptied of meaning. Having scheduled workout times creates anchors around which to organise your day. ### Sleep and physical health Exercise improves sleep quality, and [better sleep](https://www.alphabetguides.com/tag/sleep/) significantly impacts depressive symptoms. Depression and sleep problems create a vicious cycle — depression disrupts sleep, and poor sleep worsens depression. Exercise can help break this cycle by promoting more restorative sleep patterns. Irrespective of anything else, improving your physical health and fitness creates positive feedback loops. When your body feels stronger, happier, and more energetic, it is easier to manage your depression. ### Social connection When exercise happens in group settings — classes, team sports, running clubs, or gym communities it provides opportunities for social connection. Depression often involves loneliness and withdrawal from social contact. Group exercise creates low-pressure social interactions that don't require deep emotional commitment but can still help combat feelings of isolation. Even the simple act of being around other people who are also exercising, sharing space and activity, can help counter the alienation depression creates. You don't necessarily need to make friends or have conversations to benefit from the social aspect of shared movement. ## How to exercise when depressed (Practical strategies) When you're depressed, exercising can feel nearly impossible. Low motivation and fatigue are common depressive symptoms, which can also be barriers to exercising. So what can you do to make it happen? _This post is for subscribers only._ ### Mediterranean Diet: 7-Day Meal Plan URL: https://www.alphabetguides.com/mediterranean-diet-meal-plan/ Last updated: 2026-09-14T15:46:44.000Z summary - The Mediterranean diet is the most extensively studied diet that's consistently linked to a lower risk of heart disease, stroke, and type 2 diabetes. - This 7-day plan provides 28 dishes built around vegetables, legumes, whole grains, olive oil, and fish — the Mediterranean diet's core foods. - The plan adapts easily for vegetarians, people with different budgets, and varying calorie targets without compromising its foundational principles. This 7-day Mediterranean diet meal plan provides what you need to start eating the Mediterranean way. It contains 28 dishes covering [breakfast](https://www.alphabetguides.com/mediterranean-breakfast-ideas/), lunch, dinner, and snacks. Whether you're new to the Mediterranean diet or looking to refine your eating already, you'll get some ideas to enjoy healthy, flavorful dishes that can support weight loss, reduce inflammation, and increase your life expectancy. ## What is the Mediterranean diet? Just note that the Mediterranean diet is more than just a meal plan — it's a lifestyle inspired by the traditional diets and behaviours from the countries bordering the Mediterranean Sea, like Greece, Italy, and Spain. The [Mediterranean diet](https://www.alphabetguides.com/mediterranean-diet-guide/) is based on whole, minimally processed foods: lots of vegetables and fruits, whole grains, legumes, nuts, and seeds, with olive oil as the primary source of fat. They eat fish and seafood several times per week, some poultry, eggs, and dairy, and red meat and sweets are enjoyed sparingly. This makes it one of the most balanced and sustainable dietary approaches available. The benefits of the Mediterranean diet are backed by decades of scientific research. It’s the most studied diet on the planet. Research consistently shows it reduces the risk of heart disease, stroke, type 2 diabetes, and certain cancers while supporting healthy weight management and cognitive function.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/34423871/?ref=alphabetguides.com) The diet is rich in anti-inflammatory foods, rich in omega-3 fatty acids, antioxidants, and fiber helps protect against chronic disease and promote longevity. Beyond physical health, the Mediterranean approach to eating also encourages “mindful meals” shared with family and friends, regular physical activity, and an overall appreciation for fresh, [seasonal ingredients](https://www.alphabetguides.com/eat-the-seasons-the-seasonality-rule/) — making it as much about quality of life as it is about nutrition. --- ## 7-Day Mediterranean meal plan ## Day 1 ### Breakfast: shakshuka This North African dish is eggs poached in a spiced tomato and bell pepper sauce. It provides protein, lycopene, and immune-health-boosting vitamin C. Serve it with whole-grain bread for dipping. Don't skip the cumin and paprika — they're key to its authentic flavour. ### Lunch: Greek salad The combination of crisp cucumbers, ripe-vine tomatoes, kalamata olives, red onion, and feta cheese is dressed with extra-virgin olive oil and oregano, which provides heart-healthy fats, fibre, and antioxidants. For the best flavours, use vegetables at room temperature and add the dressing just before serving to keep everything crisp. ### Snack: baklava (1-2 pieces) This is a sweet treat made of flaky phyllo layers with honey-soaked walnuts or pistachios. It should be enjoyed in small portions as part of the Mediterranean diet’s philosophy of “balance and moderation”. The healthy fats from nuts make it healthier than most desserts. ### Dinner: grilled fish with lemon and herbs Fresh white fish like sea bass or snapper grilled with olive oil, lemon, and fresh herbs delivers lean protein and [omega-3 fatty acids](https://www.alphabetguides.com/superfood-oily-fish/) that support brain and heart health. Eat it with roasted vegetables and a simple arugula salad. ![stainless steel fork on brown ceramic plate](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1590412200988-a436970781fa.jpeg) Photo by [Yoav Aziz](https://unsplash.com/@yoavaziz?ref=alphabetguides.com) / [Unsplash](https://unsplash.com/?utm%5Fsource=ghost&utm%5Fmedium=referral&utm%5Fcampaign=api-credit) --- ## Day 2 ### Breakfast: whole-grain toast with avocado and tomato Avocado provides heart-healthy monounsaturated fats and fibre, while fresh tomatoes add lycopene and vitamin C. Top with a drizzle of quality olive oil, sea salt, and red pepper flakes. ### Lunch: tabbouleh with grilled chicken A Lebanese parsley salad mixed with bulgur wheat, tomatoes, mint, and lemon juice provides antioxidants and fibre, while grilled chicken adds lean protein. Let it sit for 30 minutes before serving to allow the bulgur to absorb all the flavours. ### Snack: marinated olives with citrus and herbs A mix of green and black olives marinated in olive oil with orange zest, garlic, and fresh rosemary provides healthy monounsaturated fats and polyphenols that support heart health. Bring to room temperature before serving for maximum flavour.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/21308420/?ref=alphabetguides.com) ### Dinner: seafood paella A Spanish rice dish combines shrimp, mussels, and squid with saffron-infused rice and vegetables, delivering protein, omega-3s, and the anti-inflammatory benefits of saffron. Use a wide, shallow pan to achieve the coveted crispy bottom layer called "socarrat". You can use just one type of fish to keep it simple. --- ## Day 3 ### Breakfast: Greek yoghurt with honey, walnuts and fresh figs Thick, protein-rich Greek yoghurt topped with probiotics. Add omega-3-containing walnuts and naturally sweet figs, which provide fibre and potassium. Choose full-fat Greek yoghurt for maximum satiety and better nutrient absorption2. ### Lunch: lentil soup with lemon A filling vegetarian soup that combines protein-rich lentils with vegetables, olive oil, and sharp lemon flavours. Make a large batch — it tastes better the next day as flavours get time to meld together. ### Snack: fresh dates stuffed with almonds “Nature's candy” (dates) are combined with crunchy almonds. It’s a simple snack that delivers quick energy from natural sugars, plus healthy fats and vitamin E from almonds. Medjool dates work best for their large size and smooth texture. ### Dinner: Briam (Greek roasted vegetables) This traditional Greek dish features layers of zucchini, potatoes, tomatoes, and onions slow-roasted in olive oil until caramelised and tender, providing vitamins, minerals, and phytonutrients. Serve at room temperature with crusty bread and feta cheese. --- ## Day 4 ### Breakfast: frittata with spinach, tomatoes and feta This baked egg dish with [iron-rich spinach](https://www.alphabetguides.com/superfood-leafy-greens/), antioxidant tomatoes, and tangy feta provides protein and essential nutrients. Make it in a cast-iron skillet and serve warm or at room temperature. ### Lunch: White bean and tuna salad Creamy cannellini beans paired with olive oil-packed tuna, red onion, and fresh parsley create a protein-rich, satisfying lunch high in fibre and omega-3 fatty acids. Toss with lemon juice and let it marinate for 15 minutes before eating for the best flavour. ### Snack: roasted chickpeas with paprika Crispy oven-roasted chickpeas seasoned with smoked paprika and sea salt offer a crunchy, protein-packed alternative to chips with extra stomach-filling fibre. Roast until completely crispy and store in an airtight container for up to three days. ### Dinner: lamb kebabs with tzatziki Tender lamb marinated in lemon, garlic, and Mediterranean spices provides high-quality protein and essential B vitamins, served with a cucumber-yoghurt tzatziki sauce. Serve with warm pita and a simple tomato-cucumber salad for a complete meal. ![a bowl of cucumbers and onions on a table](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1679735107918-15112296e28d.jpeg) --- ## Day 5 ### Breakfast: orange and almond semolina porridge A Cypriot-style breakfast features creamy semolina cooked with almond milk and orange zest, providing slow-release energy and vitamin C. Top with toasted sliced almonds and a drizzle of honey for added texture and natural sweetness. ### Lunch: Caprese salad with whole-grain bread Fresh mozzarella, ripe tomatoes, and basil leaves drizzled with balsamic and olive oil deliver calcium, lycopene, and heart-healthy fats. Use the highest quality ingredients you can find. ### Snack: fresh fruit with a handful of pistachios Seasonal fruit like melon, berries, or stone fruits paired with shelled pistachios provides natural sugars for energy plus protein, fibre, and heart-healthy fats. The combination of fibre from fruit and healthy fats from nuts helps stabilise blood sugar. ### Dinner: chicken souvlaki with Greek-style roasted potatoes Marinated grilled chicken skewers seasoned with oregano, lemon, and garlic provide lean protein, paired with roasted potatoes finished with olive oil and fresh lemon juice. The key is marinating the chicken for at least 2 hours—or overnight for maximum flavour. --- ## Day 6 ### Breakfast: Spinach and cheese borek These savoury Turkish pastries are made with phyllo dough, spinach, and feta, which provide calcium, iron, and B vitamins in a portable breakfast format. Brush with [olive oil](https://www.alphabetguides.com/superfood-olive-oil/) instead of butter for a more authentically Mediterranean preparation. ### Lunch: Moroccan chickpea stew Warming spices like cumin, coriander, and cinnamon transform chickpeas, tomatoes, and vegetables into a fibre-rich, [plant-based](https://www.alphabetguides.com/plant-based-diet-meal-plan/) lunch that supports gut health. Serve over couscous or with crusty bread to soak up the broth. ### Snack: cucumber rounds with labneh and za'atar Sliced cucumber topped with tangy strained yoghurt cheese (labneh) and the aromatic Middle Eastern spice blend za'atar. It offers probiotics, some hydration, and a satisfying crunch. It’s a low-calorie snack that’s refreshing and substantial enough to tide you over between meals. ### Dinner: baked cod with olives and tomatoes Mild, flaky cod baked “en papillote” with cherry tomatoes, olives, capers, and white wine creates its own flavorful sauce while locking in moisture and omega-3 fatty acids. The parchment packet steams the fish, making it easier to cook. --- ## Day 7 ### Breakfast: fig and ricotta toast with honey Spread ricotta cheese on whole-grain toast. Top with sliced fresh figs and a drizzle of honey. This provides calcium, protein, and natural sugar. Use sourdough or whole wheat bread for added fibre and complex carbohydrates. ### Lunch: panzanella (Italian bread salad) This Tuscan [salad](https://www.alphabetguides.com/mediterranean-salads/) combines day-old bread with tomatoes, cucumber, red onion, and basil, dressed in olive oil and red wine vinegar. The bread soaks up the vegetable juices and dressing. ### Snack: hummus and whole-grain flatbread Creamy chickpea hummus provides [plant protein](https://www.alphabetguides.com/plant-based-protein/) and fibre, while whole-grain flatbread gives you energy from complex carbohydrates. Drizzle extra olive oil and sprinkle with paprika or za'atar for authentic flavours and presentation. ### Dinner: moussaka This Greek casserole layers roasted eggplant with spiced meat sauce and béchamel sauce. It provides protein, antioxidants, and complex flavours that get better if left overnight. Make ahead and reheat for better flavours. ![a plate of hummus, pita bread, and a bowl of hummus](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1697126248437-db26a30024c5.jpeg) Photo by [Imad 786](https://unsplash.com/@imad8321?ref=alphabetguides.com) / [Unsplash](https://unsplash.com/?utm%5Fsource=ghost&utm%5Fmedium=referral&utm%5Fcampaign=api-credit) --- ## How to customise this meal plan for your goals _This post is for subscribers only._ ### Does Exercise Lower Blood Pressure? (And by How Much?) URL: https://www.alphabetguides.com/exercise-lowers-blood-pressure/ Last updated: 2026-09-22T10:08:16.000Z summary - Regular exercise reduces systolic blood pressure by 3–4 mmHg in healthy adults, and by 7–11 mmHg in people with hypertension. - Isometric exercises (e.g., wall sits, planks, and handgrip exercises) produce the largest reductions of any exercise type, averaging 11 mmHg systolic. - Exercise produces blood pressure reductions comparable to some basic antihypertensive medications, but without the side effects. High blood pressure (otherwise known as 'hypertension') affects nearly half of all adults and is a leading risk factor for heart disease and stroke. This article explains how exercise can lower blood pressure, which types of physical activity are most effective, and why regular movement is a proven, drug-free approach for managing blood pressure. If you've been told your blood pressure is creeping up, or you've been diagnosed with hypertension, you've probably heard that exercise can help. But does it actually work? Is it worth the effort? And what types of exercise are most effective? The research provides pretty clear (and encouraging) answers ... Regular physical activity is one of the most reliable ways to lower blood pressure, with benefits that often rival those of prescription medications. Most types of exercise work for most types of people.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/37491419/?ref=alphabetguides.com) For your average adult, taking part in plain old aerobic exercise typically knocks 3 to 4 mmHg off your systolic blood pressure (“the top number”) and 2 to 3 mmHg off your diastolic pressure (“the bottom number”). While these numbers might not sound like a lot, it's still clinically meaningful. Even a few points off your blood pressure can lower your risk of heart attack, stroke, and other cardiovascular health issues. The benefits become even more impressive for people who have high blood pressure already. Structured exercise programs can reduce systolic blood pressure by 7 to 11 mmHg and diastolic by 4 to 5 mmHg in people with high blood pressure. These are substantial drops that can move someone out of the 'hypertensive range'. ## What exercise lowers blood pressure the most? One of the most practical findings from the research is that you don't need to stick to just one type of exercise. Several types of exercise can lower blood pressure, giving you the flexibility to choose activities you enjoy and will stick with. ### Aerobic exercise Traditional aerobic (or “cardio”) physical activity, like walking, jogging, cycling, and swimming, is the most well-studied. They consistently lower both resting and “ambulatory” blood pressure (the readings taken throughout your day as you go about normal activities). The beauty of aerobic exercise is that it’s relatively easy to do — you can start with simple [walking](https://www.alphabetguides.com/why-walking-beats-running/) and gradually build up intensity and duration as your fitness improves. ### Resistance training [Resistance exercise](https://www.alphabetguides.com/minimalist-muscle-growth/) using weights or resistance machines can lower blood pressure as well. It can work as a stand-alone intervention, meaning you can use it to reduce your blood pressure if traditional cardio isn't your thing. ### Isometric exercise: the most underrated option Isometric exercises: activities where you hold a static position without moving, have some of the largest blood pressure drops. Think wall sits, hangs, holds, planks, or handgrip exercises. These produce reductions averaging 11 mmHg for systolic pressure and 6 mmHg for diastolic pressure.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/23525435/?ref=alphabetguides.com) The appeal of isometric exercise is its efficiency. You can achieve significant benefits with relatively short sessions, making this approach particularly attractive for people with limited time. A few minutes of wall sits or handgrip exercises several times per week can meaningfully lower your blood pressure. ### Combined training Programs that mix aerobic and resistance exercise also lower blood pressure. This combination approach may be ideal for overall cardiovascular health, as it provides the benefits of both training types while adding variety to keep workouts interesting. ## How does exercise compare to blood pressure medication? One of the most impressive findings is how exercise stacks up against drugs. Research shows that in people with hypertension, regular structured exercise yields similar reductions in blood pressure compared to many first-line 'anti-hypertensive' medications.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/30563873/?ref=alphabetguides.com) This doesn't mean abandoning prescribed blood pressure medications in favour of exercise. But it does go to show that exercise is a legitimate, powerful tool to manage blood pressure — not just a minor add-on to the “real” treatments. For some people with borderline hypertension (sometimes called “pre-hypertension”) or those who prefer to avoid medication when possible, exercise may help. For others already on medication, adding regular exercise can enhance the effects of their drugs, potentially allowing for less medication (under professional guidance, of course). ## How quickly does exercise lower blood pressure? The great thing about exercise is that the benefits can be seen after your very first session. Exercise triggers an immediate reduction in blood pressure (“post-exercise hypotension”), which can last for up to a day, giving you immediate decreases in blood pressure.[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC10342491/?ref=alphabetguides.com) However, the more powerful and lasting effects come after training consistently for weeks or months. This is where your blood pressure stays lower around the clock, not just temporarily for a few hours after exercising. ## How does exercise lower blood pressure? Scientists have identified several ways that exercise reduces blood pressure, helping us refine recommendations. The main way exercise lowers your blood pressure is by relaxing your blood vessels and making them more flexible, which allows your blood to flow better. It also decreases the activity of your“fight or flight” system, which by itself increases blood pressure. --- ## How much exercise do you need to lower blood pressure? _This post is for subscribers only._ ### Does Exercise Help Anxiety? URL: https://www.alphabetguides.com/exercise-and-anxiety/ Last updated: 2026-09-22T10:08:47.000Z summary - Exercise reduces mild to moderate anxiety across all ages and types, with effects comparable to medication or therapy. - Physically active people are significantly less likely to develop anxiety disorders, suggesting exercise has a meaningful preventive effect. - Moderate-intensity aerobic or resistance exercise a few times per week is a good evidence-based target to start with, but any exercise helps. Anxiety affects millions of people worldwide, causing excessive worry, nervousness, and physical symptoms that interfere with daily life. This article explains how exercise can reduce anxiety symptoms, which types are best, and why physical activity is one of the best natural, evidence-based ways to manage anxiety. If you've ever felt your worries quiet down after a brisk walk or noticed your racing, sporadic thoughts slow down during a workout, it is probably not a coincidence. There is a growing body of scientific evidence which confirms what many people experience firsthand: exercise *can* be used to manage anxiety. For the millions of adults and children who struggle with anxiety — whether it’s just an occasional worry or more serious diagnosed anxiety disorders, there is hope. Physical activity isn't just good for [your body and your health](https://www.alphabetguides.com/tag/exercise/). It's also one of the most effective and easiest ways to support your mental health as well. Exercise and being physically active reduce anxiety symptoms in a lot of different people: healthy adults, those with medical conditions, those with mild anxiety and those with serious diagnosed anxiety disorders. It’s not just about feeling slightly better after a workout (although that helps too). The benefits are comparable to some of the standard treatments for mild to moderate anxiety, like medications or talking therapies.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/36796860/?ref=alphabetguides.com) What makes exercise particularly compelling is that there are consistent benefits across different types and causes of anxiety, whether that’s general anxiety, social anxiety, stress-related anxiety, or anxiety symptoms. ## Does exercise prevent anxiety? Perhaps the most profound discovery is that staying physically active may *prevent* you from developing anxiety disorders in the future. Research shows that physically active people have a lower chance of developing anxiety problems in the first place.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/36796860/?ref=alphabetguides.com) The 'protective effect' of exercise extends (again) across different types of anxiety, including generalised anxiety disorder, agoraphobia, and even post-traumatic stress disorder (PTSD). So, rather than waiting until anxiety becomes a problem, building regular exercise into your life now may help keep anxiety at bay in the future. ## It works across all ages One of the most encouraging findings is that exercise helps with anxiety regardless of your age. Both younger and older adults can reduce their anxiety by being physically active. [Children and adolescents also benefit](https://www.alphabetguides.com/weighlifting-children-teens/) from regular physical activity. Studies on young people show reductions in “state anxiety” (that temporary feeling of nervousness or worry) when kids and teens engage in structured exercise programs. This matters a lot, as anxiety disorders often first appear during childhood or adolescence. So, establishing healthy coping strategies early in life can set the foundation for maintaining good mental health.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/33618056/?ref=alphabetguides.com) ## What is the best exercise for anxiety? Good news: multiple types of exercise can help fight anxiety symptoms. [Aerobic exercise](https://www.alphabetguides.com/improve-your-vo2max/) like running or cycling, resistance training with weights, mixed programs that combine both, and “mind-body” practices like yoga and tai chi are all effective. Interestingly, research suggests that low-intensity yoga and other mind-body exercises may also be effective for anxiety. This type of exercise tends to combine physical movement with breathing exercises and mindfulness, addressing anxiety through multiple pathways all at the same time.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/30043270/?ref=alphabetguides.com) However, standard aerobic (or “cardio”) exercise is the most studied and most consistent type of exercise for helping anxiety. This includes activities like walking, jogging, swimming, or cycling — anything that gets your heart rate up above resting levels and keeps it there. Resistance training, whether it’s lifting weights or bodyweight exercises, also shows meaningful reductions in anxiety. There is some evidence to suggest that the [intensity](https://www.alphabetguides.com/what-are-training-zones/) of your workout matters more than the type of activity. Moderate to vigorous intensity exercise tends to produce better anxiety reductions than low-intensity exercise, although both are effective.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/36796860/?ref=alphabetguides.com) So this doesn't mean you need to push yourself to exhaustion — it simply means exercising at a level where you're breathing harder than normal but can still carry on a conversation. And if you can’t exercise at a moderate intensity level, any exercise is better than none! ## The setting matters too Here's something that might surprise you: where and how you exercise can influence the anxiety-reducing benefits you get. Research shows that supervised, group-based exercise programs often produce *better* anxiety outcomes than unsupervised workouts at home. This doesn't mean solo runs or home workouts are ineffective — they definitely help. But if you're specifically exercising to manage anxiety, consider structured classes, group fitness sessions, or working with a trainer. The scientists seem to think the combination of professional guidance, social connections, and accountability may amplify the anxiety-reducing effects of exercise. ## How does exercise reduce anxiety? Researchers have identified how exercise reduces anxiety. It changes both your biological and psychological systems. On a biological level, regular physical activity reduces inflammation and oxidative stress throughout your body, including your brain.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/23415701/?ref=alphabetguides.com) Exercise also promotes the production of “brain-derived neurotrophic factor”, a substance that supports the growth and health of neurons in your brain, which helps regulate mood and anxiety. Psychologically, exercise is also thought to serve as a form of “exposure therapy” for the physical sensations associated with anxiety. Think about what happens when you exercise: your heart rate increases, you breathe harder, and you might feel sweaty, clammy or warm — sensations similar to those that occur during anxiety or panic modes. Regularly experiencing these sensations in a safe, controlled and predictable environment (via exercise) can help your brain learn that these bodily feelings aren't dangerous and improve your [resilience to stress](https://www.alphabetguides.com/what-is-cortisol/). Exercise also builds 'self-efficacy', which is confidence in your ability to accomplish goals and overcome challenges. Your ability to do something about something (it's about control).

URL: https://www.alphabetguides.com/types-of-intermittent-fasts/ Last updated: 2026-09-18T10:07:03.000Z summary - Earlier eating windows consistently produce better weight loss and metabolic health outcomes than later windows of the same duration. - Alternate-day fasting and 5:2 fasting protocols had higher drop-out rates than time-restricted eating. - All major intermittent fasting protocols produce similar weight loss when they are adhered to, so pick one you'll follow. Intermittent fasting is not one diet — it is a family of (slightly) different eating 'patterns' that share a common principle: periods of not eating followed by periods of normal eating. This article explains the main types of [intermittent fasting](https://www.alphabetguides.com/intermittent-fasting-diet/) out there. We’ll cover the science behind each one and explain how to choose the one that best fits your goals and lifestyle.So, if you have decided to try intermittent fasting, the first problem you’ll run into is which one? There are a few options: “16:8”, “5:2”, “alternate-day fasting”, “one meal a day” or “time-restricted eating”. The terminology can be confusing, and the claims for each type vary wildly. Some people simply call what they are doing intermittent fasting when, really, they're talking about one specific protocol. There is no single “best” type of intermittent fasting, but some types are better than others, and some suit certain people, while others don’t. ## What counts as intermittent fasting? Different intermittent fasting protocols vary in how often you fast, how long you fast for, and how strict the fast is, meaning what or how many calories you’re allowed to eat during the 'fasting period'. Most intermittent fasting protocols are grouped under two branches: 1. Time-restricted eating: where you eat within a defined daily window and then fast for the rest of the day. 2. Periodic fasting: where you eat normally on some days and then fast, or significantly reduce your calories, on other days of the week. Both types trigger the same underlying “[fasting response](https://www.alphabetguides.com/the-fasting-timeline-what-happens-to-your-body-hour-by-hour/)”, which includes falling insulin levels and increased fat burning. However, most people tend to prefer one approach over another.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/28715993/?ref=alphabetguides.com) ## Time-restricted eating: daily fasting windows The basic principle of time-restricted eating is that you eat all your food within a set number of hours each day, then fast for the rest. Here are the main types: ### 12:12 fasting: the beginner's starting point This is the entry-level version. For many people, it is already their default eating pattern (e.g., finishing their last meal of the day at 8 pm, eating breakfast at 8 am). There is limited specific research on 12:12, but it's a reasonable starting point for beginners and serves as a gentle introduction to intermittent fasting. The benefits of this type of fast are really more about establishing a fixed eating schedule and cutting out the late-night snacks (which [derail your sleep](https://www.alphabetguides.com/tag/sleep/)). ### 14:10 fasting: the next step up This is the next step up. It is typically achieved by skipping a late-night snack or delaying breakfast slightly (by an hour or so). Some evidence suggests that 14-hour fasting windows may begin to produce measurable improvements in metabolic health markers, although most research is generally focused on longer fasting windows.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/28715993/?ref=alphabetguides.com) ### 16:8 fasting: the most popular protocol This is the most researched time-restricted eating protocol and, for most people, the practical “sweet spot”: balancing practicality with the health benefits. A typical pattern is eating between noon and 8 pm, then fasting overnight and through the morning til noon the following day. Studies consistently show that 16:8 fasts help people lose weight by reducing overall calorie intake. There are also some metabolic health benefits as well (e.g., improved insulin sensitivity, reduced blood pressure, improved blood lipid profile).[\[2\]](https://pubmed.ncbi.nlm.nih.gov/36349432/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/34633860/?ref=alphabetguides.com) In addition to the length of the window, the timing of the window also seems to matter. Earlier eating windows (e.g., 8 am to 4 pm, or earlier) generally produce better weight loss and health benefits than later ones. Your body tends to process food better (and more efficiently) in the morning/daylight hours than late in the evening.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/36702768/?ref=alphabetguides.com) ### 18:6 and OMAD (one meal a day) An 18:6 window (eating within 6 hours, fasting for 18) and OMAD (one meal a day, effectively a 23:1 pattern) are more extreme approaches. They extend the positive effects of fasting but also come with trade-offs. The longer fasts tend to be more difficult to adhere to, and the small eating windows also make it difficult to meet your [nutritional needs](https://www.alphabetguides.com/tag/nutrition/), particularly getting enough protein, fibre and some micronutrients in such a small eating window. --- ## Periodic fasting: whole-day and multi-day approaches Rather than restricting the hoursduring which you eat each day, 'periodic fasts' assign specific fasting (or low-calorie) days across the week. ### 5:2 fasting: the most flexible option The 5:2 diet involves eating normally five days and restricting calories on two non-consecutive days, typically to around 500–600 calories. It is popular partly because of its flexibility: you only need to manage two difficult days, and those days can be scheduled around your week. Studies show that the “5:2” approach produces similar weight loss to time-restricted eating and normal calorie-restriction diets. However, the main advantage of the 5:2 pattern is its flexibility and reduced 'mental workload'. Some people find it more manageable to endure two “strict days” a week, compared to maintaining eating restrictions every day of the week.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/36349432/?ref=alphabetguides.com) Again, the main disadvantage is that the fasting days are more difficult and uncomfortable compared to other types of fasts. Hunger, low energy and difficulty with work or concentrating are all commonly reported. ### “Alternate-day fasting” — fasting every other day As the name states, alternate-day fasting involves alternating between restricted days and unrestricted days after another. In its strictest form, the 'fasting days' mean no food whatsoever. However, some protocols allow a small amount of food (around 500 calories) on the fasting days. As you can imagine, alternate-day fasts generally lead to the quickest, most effective weight loss (and some health benefits) in the short-term. However, just like the 5:2 fasts, the longer and more frequent fasting periods are generally more difficult to maintain.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/36349432/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/40731344/?ref=alphabetguides.com) Researchers report that participants in their studies were around *three* times more likely to give up on 5:2 and alternate-day fasts compared to time-restricted eating or just normal calorie-restricted diets.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/36349432/?ref=alphabetguides.com) --- ## Beyond intermittent Fasting: other fasting protocols ### Extended fasting (24–72+ hours): These longer fasting periods trigger different physiological responses: [ketosis](https://www.alphabetguides.com/keto-diet/), [autophagy](https://www.alphabetguides.com/autophagy-and-fasting/) and measurable changes in your hormone levels. Extended fasts are not routinely recommended for weight loss and general health, as they carry extra medical risks and should be medically supervised. ### Fasting-mimicking diet: This is a 5-day cycle of a very-low-calorie diet, but eating certain nutrient-dense foods, mainly plants. This protocol is designed to “mimic” the physiological effects of fasting but without entirely avoiding food. It is generally done less frequently (e.g., once a month or less) than other types of fasts, but there is some promising research on it.[\[7\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6816332/?ref=alphabetguides.com) We've done a full review and sample menu of the fasting mimicking diet. [Fasting Mimicking Diet: A ReviewA structured, periodic low-calorie protocol designed to trigger the benefits of fasting without full abstinence.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-de141645-041c-4d9d-a16b-e054fd15be55.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1469307517101-0b99d8fb0c33-6b0c66db-f9c0-4783-9518-5428b329202f.jpeg)](https://www.alphabetguides.com/fasting-mimicking-diet/) ### Religious and cultural fasts: People have been fasting for centuries. It is not a new thing at all. Fasts are routinely undertaken in many religions, and many resemble intermittent fasting protocols. However, because these types of fasts aren’t specifically designed for health reasons and they're also combined with other religious practices (which may or may not be good for health), we don't recommend them. ## Which intermittent fasting protocol is best for you? _This post is for subscribers only._ ### Why Seasonal Vegetables are Healthier URL: https://www.alphabetguides.com/eat-the-seasons-the-seasonality-rule/ Last updated: 2026-09-22T09:52:05.000Z summary - Vegetables harvested at peak ripeness retain more nutrients; vitamin C, folate, and antioxidants begin degrading immediately after harvest. - Seasonal eating naturally varies plant food intake, which is linked to a more diverse, health-supporting gut microbiome. - Local seasonal produce has a lower carbon footprint and needs fewer pesticides and energy-intensive growing technology than imports do. Seasonal vegetables are those harvested at their natural time, when ripe. They generally retain more flavour and nutrients than out-of-season produce. This article reviews evidence of whether seasonality actually affects nutrient content, taste, and the environment. Supermarkets offer strawberries in December and tomatoes in January. This year-round availability is convenient, but it comes at a cost — to your nutrition, your palate, and the planet. “Seasonal eating” means consuming [fruit and vegetables](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/) at their natural harvest time in your home region or country, which offers additional benefits that convenience can't offset. Traditionally, people had no choice in what they ate. They consumed what nature provided when it provided it. Eating with the seasons wasn't an option. This inadvertent seasonal eating pattern meant automatically consuming a diverse array of vegetables throughout the year as different crops came into harvest. Research shows that the more different [plant foods](https://www.alphabetguides.com/tag/plant-based/) you consume, the more diverse your microbiome is (which is associated with better health). Seasonal eating naturally encourages this diversity.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/29795809/?ref=alphabetguides.com) The case for seasonal vegetables rests on four pillars: better nutrition, better flavour, lower environmental impact, and lower cost. When vegetables ripen naturally under optimal conditions, they develop their full spectrum of vitamins, phytonutrients, and flavour compounds. They don't need to be picked unripe for shipping and then stored for months.[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC10969708/?ref=alphabetguides.com) ## The nutritional advantage Vegetables harvested at peak ripeness contain significantly higher nutrient levels than those picked early for transport. A tomato allowed to ripen fully on the vine develops more of some nutrients than one picked green and ripened artificially. The same principle applies to most vegetables — natural ripening allows complete development of [beneficial compounds](https://www.alphabetguides.com/3-healthiest-vegetables-around/).[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8869745/?ref=alphabetguides.com) Local, seasonal vegetables spend less time in storage and transport, minimising nutrient degradation. Vitamin C, folate, and certain antioxidants begin breaking down immediately after harvest. The difference between a courgette picked yesterday at a local farm and one shipped from another continent is noticeable, both nutritionally and in taste. Flavour also peaks at the natural harvest time. Spring asparagus, summer tomatoes, autumn squash, and winter greens each taste distinctly better when in season. This isn't nostalgia or imagination — it's fact. Vegetables develop their characteristic flavours through complex chemical processes during ripening that can't be replicated in storage or through artificial ripening. ## The environmental case Food transportation contributes significantly to greenhouse gas emissions. A kilogram of onions shipped from the opposite side of the world will have a higher carbon footprint compared to a kilogram of locally grown onions. Seasonal eating reduces the demand for energy-intensive growing methods like heated greenhouses and the production of chemical fertilisers. Growing vegetables outdoors, in-season, will reduce the energy and environmental cost of food. Supporting local farms that grow seasonally can promote sustainable agricultural practices. These farms typically use fewer pesticides, maintain soil health better, and preserve biodiversity. Your purchasing choices directly influence farming methods and encourage alternatives to large-scale industrial agriculture. ## The diversity principle Perhaps the strongest argument for seasonal eating relates to the variety of foods you end up eating, which is linked to health. Particularly for your gut microbiome, the trillions of bacteria living in your digestive system like a diverse range of foods. Different vegetables provide different types of fibre and 'phytonutrients', feeding different bacterial species in your gut. A more diverse microbiome is linked with better immunity, lower inflammation, improved mental health, and reduced risk of many chronic diseases. Seasonal eating forces variety into your diet. You can't eat the same vegetables year-round when you follow the seasons.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/35461318/?ref=alphabetguides.com) Spring brings asparagus, peas, and young greens. Summer offers tomatoes, courgettes, and peppers. Autumn provides squash, root vegetables, and brassicas. Winter features [hardy greens](https://www.alphabetguides.com/superfood-leafy-greens/), roots, and vegetables that can be stored pretty well. Note the [different colours](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/) with the seasons. This natural rotation ensures you're constantly feeding your microbiome different things. --- ## Spring: asparagus and pea risotto Celebrating spring's tender, green, delicate vegetables. ![Asparagus and pea risotto.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1621341258668-b2bf005a9f97.jpeg) ### Ingredients - 300g (10 oz) asparagus - 150g (1 cup) fresh or frozen peas - 300g (1.5 cups) risotto rice - 1 litre vegetable stock (kept warm) - 1 onion (finely diced) - 2 garlic cloves (minced) - 100ml white wine (optional) - 40g (1.5 oz) Parmesan (grated) - 3 tbsp extra virgin olive oil - zest of 1 lemon - fresh mint ### Directions 1.

Leafy greens are nutrient-dense: high in vitamins, minerals, fibre, and other substances that support health. This article summarises the main health benefits associated with regular intake of leafy greens. Spinach, kale, rocket (or arugula), Swiss chard, lettuce, and pak choi are all examples of leafy greens. They're full of nutrients, but two stand out: *nitrate* and *vitamin K1*. Even though leafy greens can be eaten year-round, they are largely absent from most Western diets, and so are nitrate and vitamin K1, which are very difficult to obtain from other foods. The benefits of leafy greens extend well beyond being one of your “5 a day”. These foods provide specific compounds at concentrations that can measurably affect your cardiovascular and bone health in ways that other foods can't match. ## Are leafy greens actually healthy? ### Nitrate Dietary nitrate is converted in the body into nitric oxide. It’s a molecule that keeps your blood vessels (and thus your blood pressure) healthy. Nitric oxide helps blood vessels relax and widen, which lowers blood pressure and improves [blood flow](https://www.alphabetguides.com/blood-flow-restriction-training/). Leafy greens are the primary dietary source of nitrate — spinach and rocket can contain 300-500 mg per 100g, while other vegetables contain far less. ### Health benefits Regularly eating leafy greens is linked with better [cardiovascular health](https://www.alphabetguides.com/tag/heart-health/). Several studies have reported that dietary nitrate lowers systolic blood pressure (by \~8 mmHg) and improves the way your blood vessels function.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4973479/?ref=alphabetguides.com) Importantly, the benefits are seen even at moderate intakes. One study found that consuming around 60 mg of vegetable nitrate per day (roughly one cup of leafy greens) was associated with lower cardiovascular risk, with diminishing returns beyond eating this amount.[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8416839/?ref=alphabetguides.com) ### Vitamin K1 Vitamin K1 ('phylloquinone') is found almost exclusively in green [coloured vegetables](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/), with leafy greens providing by far the largest amount of it. Vitamin K1 is essential for activating a protein called “osteocalcin”, which helps get calcium into bones, making them stronger and healthier. When vitamin K intake is low, it may contribute to weaker bones and fracture risk. Several studies have shown that either supplementing or getting vitamin K1 from your diet increases osteocalcin and reduces bone fracture risk. One large cup of leafy greens can provide the recommended daily amount of vitamin K1.[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC7645307/?ref=alphabetguides.com) ### Additional benefits Beyond nitrate and vitamin K1, leafy greens also provide several other essential nutrients: folate, vitamins A, C, and E, magnesium, potassium, calcium (especially in varieties like kale and collards), and iron. They're also rich in antioxidants such as carotenoids (like 'lutein' and 'zeaxanthin') and 'polyphenols', which support eye health and help protect your cells. A typical 100g serving of cooked spinach or kale provides 20-50% of your daily vitamin C, 100-200% of vitamin A, folate, and meaningful amounts of calcium and iron — all for less than 30 calories. Leafy greens are probably the most nutrient-dense whole foods you can get for the fewest calories. --- ## How to eat more leafy greens ### #1\. Make them invisible If you don't enjoy the taste or texture of leafy greens, blend them into smoothies with other foods like bananas, berries, and yoghurt. A handful of spinach or kale adds (virtually) no flavour but provides nutrients. You can also finely chop them and stir through pasta sauces, soups, curries, or minced dishes in the last few minutes of cooking. Their taste tends to mellow when cooked, and because they lose most of their volume, they become unnoticeable. ### #2\. Season aggressively Fresh leafy greens can taste bitter or bland to some people. Counteract this by using strong flavours with them: garlic, lemon juice, soy sauce, chilli flakes, or Parmesan. Wilted spinach with garlic and lemon is a classic for good reason. “Massaged” or “bruised” kale salads (where you rub leaves with olive oil and salt to break down tough fibres) mixed with dried fruit, nuts, and a tangy dressing can cover their flavour. ### #3\. Buy pre-washed and frozen Fresh leafy greens spoil quickly, which can be a problem if you eat them regularly. Pre-washed salad mixes and baby spinach in bags or boxes eliminate washing and prep time. Frozen spinach is nutritionally equivalent to fresh spinach. It lasts months in the freezer, and can be added directly to hot dishes (like soups or stews) without thawing. Keep a few bags on hand for when your fresh greens run out. --- ## Bottom Line Leafy greens are one of the most nutrient-dense foods available and provide two unique compounds: nitrate and vitamin K1, which are difficult to obtain elsewhere and have well-established health benefits (particularly cardiovascular and bone health). Just a single daily serving can make a measurable difference to your health. Whether you blend them into smoothies, wilt them into casseroles, or eat them in salads, getting more leafy greens into your diet is a straightforward, evidence-based way to improve health.

Exercising for body recomposition focuses on progressive [resistance training](https://www.alphabetguides.com/resistance-training-beginners/), which is designed to stimulate muscle growth while maintaining or reducing your body fat levels. This article provides workout and training principles aligned with your recomposition goals. Body recomposition: the [simultaneous](https://www.alphabetguides.com/body-recomposition-lose-fat-gain-muscle/) reduction of fat and increase in muscle, represents a different approach to defining what a “healthy” physical change is. Rather than simply making your body smaller, body “recomposition” focuses on improving what your body is made of. ## Beyond body weight: body composition Your total body weight consists of many parts: fat mass, skeletal muscle, organs, bones, nerves, water, and connective tissue, to name a few. When you step on scales, you're measuring all of these components together. Whereas body composition refers to how “much” of these different tissues you have, usually their relative proportions to each other (or sometimes your relative proportions to your height). The most commonly used body composition measure is the ratio of fat you have relative to your fat-free mass (i.e., muscle, bone, and other non-fat tissues). But many others are looked at as well. The distinction between body weight and body composition matters a lot. Two people of the same height and weight can look completely different and have vastly different health profiles depending on their body composition. The person with more muscle mass and less fat tissue generally has better health prospects, greater functional capacity, and lower disease risk — even if they weigh the same as someone with more fat and less muscle. ## Mechanical tension: the primary biological signal [Weightlifting](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/) is key to training for body recomposition. There is no way around it. When you lift a weight, your muscles generate force in order to move that load, be it a barbell, dumbbell, kettlebell, or your own body weight. This creates “mechanical tension” in your muscle, just like when you flex or 'tense' your muscles when posing in the mirror. When you “overload” a muscle, meaning you lift weights until they are either too heavy to lift or you become too tired to lift them anymore, your body recognises this tension in your muscle as a signal to grow and become stronger.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/20847704/?ref=alphabetguides.com) Your muscle does this by growing your individual [muscle cells (or muscle “fibres”)](https://www.alphabetguides.com/muscle-fibre-types/), which make more protein (than they normally do) and therefore end up getting bigger and stronger. ## From signal to structure: "Muscle Protein Synthesis" After a heavy bout of resistance training, your body starts the process of making more muscle protein, which lasts for up to 48 hours (assuming you’re eating enough protein). The training provides the signal, and the dietary protein provides the material for you to build new muscle. It is important to understand that you aren’t simply repairing the muscle that has been worn and torn and restoring it to its previous state. It’s an adaptive process. You are repairing the damage, *and* you're making more muscle, and stronger muscle, making it more capable of handling stress in the future. All of this is happening at the cellular level, meaning you aren’t going to notice any growth after a single session. However, over time, and with repeated training, these small changes will accumulate into noticeable changes (in both strength and size). --- ## What about cardio? Studies show that aerobic exercise (or cardio) can burn fat, but it doesn’t build (large amounts of) muscle. But does this mean it has no place in your recomposition plan? Not necessarily. Aerobic exercise, like [walking](https://www.alphabetguides.com/why-walking-beats-running/), cycling, and [running](https://www.alphabetguides.com/why-running-is-better-than-walking/), increases energy demands and burns calories, which can help create the energy deficit needed for fat loss.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/23019316/?ref=alphabetguides.com) Although you are undoubtedly using your muscles, it doesn’t seem to generate the amount of mechanical tension required to trigger meaningful muscle growth. The contractions your muscles are doing during cardio are light, low-force, and repetitive, which doesn’t challenge the muscle in the same way heavy resistance training does. This doesn’t mean you should avoid cardio. In fact, it offers several [health benefits](https://www.alphabetguides.com/improve-your-vo2max/) and can actually help you lose fat. However, it is not a substitute for resistance training. But if you want to maximise body recomposition (and general health), you should probably be doing both. ## Progressive overload: adaptation requires progress Your body will adapt to the demands placed upon it. Once it has successfully adapted to a given amount (or intensity) of work, that 'stress' is no longer challenging enough to trigger any further adaptations. This is why “progressive overload”, gradually increasing training demands over time, is needed for continued growth. This doesn’t necessarily mean consistently adding weight to the bar (although it's the most common way to do it) — it can involve increasing the number of reps, sets, reducing the rest period, or even improving your technique or form. This is particularly important for body recomposition, as maintaining (or increasing) the training volume is one of the key determinants of [preserving muscle mass](https://www.alphabetguides.com/minimalist-muscle-growth/) during energy deficits. ## Training during an energy deficit: difficult but not impossible There's a common misconception that you cannot build muscle in an energy deficit, only maintain it. Whilst an energy deficit indeed creates constraints and is not optimal, it doesn't eliminate your ability to build muscle if you weight train. When combined with adequate dietary protein intake, resistance training can stimulate muscle growth. Yes, it is not as easy or efficient as building muscle while in a calorie surplus — but it *can* still be done.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31915482/?ref=alphabetguides.com) The size of the deficit matters. Very large deficits (over 500 kcal a day) will impair the capacity to build muscle, and it’ll also impair your ability (or thus quality) of your training, which will indirectly affect your capacity to stimulate growth. Generally, the smaller the energy deficit, the better your chances are of preserving or building muscle. For [optimising recomposition](https://www.alphabetguides.com/body-recomposition-series/), rather than fat loss, very large calorie deficits should be avoided.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/34623696/?ref=alphabetguides.com) ## The indirect benefits: how muscle growth supports fat loss Beyond directly building muscle, resistance training offers several indirect benefits that [support fat loss](https://www.alphabetguides.com/3-underrated-ways-to-lose-fat/). Whilst these aren’t going to be the primary drivers of fat loss, they will certainly help. First, muscle is metabolically active, so increasing muscle mass does contribute to a higher resting [metabolic rate](https://www.alphabetguides.com/basal-metabolic-rate/), meaning you burn more calories throughout the day. Over a year, five extra kilograms of muscle will use the energy equivalent of about 2-3 kg of fat. Second, resistance training itself burns energy, both during the workout and even for a few days after exercise. The more training you do, the more energy you’ll expend. This can accumulate over time and meaningfully increase your energy expenditure. Third, the more muscle you have and the stronger that muscle is, the more your work capacity increases. You can move more weight, more often, and increase your training volume over time. This means higher energy expenditure. It may also make daily activities easier and may encourage you to be more physically active.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/10956341/?ref=alphabetguides.com) Finally, the muscle itself can influence your metabolism. Trained muscle becomes more efficient at utilising fat as a fuel source, particularly at rest and during lower-intensity activities. This may help fat-loss pursuits. ## The non-negotiable foundation The message is straightforward: if body recomposition is your goal, resistance training isn't optional — it's essential. No amount of protein, no degree of caloric deficit, and no volume of cardio can substitute for it. You don't need to spend [hours in the gym](https://www.alphabetguides.com/minimalist-muscle-growth/) either. [Body Recomposition: A 5-Part SeriesA series of lessons on body recomposition, explaining how you can lose fat and gain muscle at the same time.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-90abde86-35dc-4e2b-aee7-7c5e7718df4e.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1781800937305-5a2618f03ae4-d9119f2f-f329-4c62-9f7b-535f1160e713.jpeg)](https://www.alphabetguides.com/body-recomposition-series/) --- ## Frequently Asked Questions _This post is for subscribers only._ ### Which Colour Vegetables are Healthiest? URL: https://www.alphabetguides.com/eat-the-rainbow-colour-matters/ Last updated: 2026-09-22T09:55:12.000Z summary - Eating a variety of coloured vegetables provides extra health benefits beyond simply eating more vegetables. - Red vegetables contain lycopene; orange and yellow provide carotenoids; purple and blue supply anthocyanins, each having different health benefits - Aim for at least two different colours of vegetables per meal and cover each colour group once a week. Vegetable colour reflects different 'phytonutrients' and 'antioxidants' that have specific health effects. This article summarises how colour relates to nutrition and which coloured vegetables are healthiest. Walk through any produce market, and you'll notice vegetables come in a wide variety of different colours — deep purples, reds, yellows, greens, even pristine whites. These colours aren't just visually appealing; they're nature's way of signalling different nutrients and health benefits. They are coloured and vibrant because they want to be eaten. They want to spread their seed, wide and far. The pigments that give vegetables their colours are also 'phytonutrients'. Research involving over 37 million people found that consuming a variety of different coloured vegetables provides unique health benefits beyond simply eating [more vegetables](https://www.alphabetguides.com/half-plate-rule-eat-your-vegetables/) overall. Different colours correspond to different types of phytonutrients, each working in different ways in your body.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/35807307/?ref=alphabetguides.com) The “eat the rainbow” rule offers simple, practical advice for ensuring nutrient diversity in the diet. Rather than obsessing over measuring and counting individual nutrients, simply include multiple colours in your weekly meals. --- ## Red and pink vegetables Tomatoes, red peppers, red cabbage, radicchio, and radishes owe their colour to compounds like lycopene and anthocyanins. Lycopene, particularly rich in tomatoes, has been studied for its potential role in reducing the risk of prostate cancer. These compounds also support cardiovascular health, having antioxidant and anti-inflammatory properties.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/32768949/?ref=alphabetguides.com) Cooking tomatoes in olive oil actually increases lycopene 'bioavailability' — meaning your body absorbs more of it (up to five times) than when it is cooked in other fats. This makes tomato-based sauces, roasted red peppers, and braised red cabbage in olive oil not just delicious but a nutritionally strategic choice. ## Roasted tomato and red pepper soup A vibrant, lycopene-rich soup that contains two red vegetables at their best. ![Red soup in white ceramic bowl.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1608949621301-dc970e104c90.jpeg) ### Ingredients (serves 4-6) - 1kg ripe tomatoes - 3 red peppers - 1 red onion - 4 garlic cloves - 3 tbsp EVOO - 500ml vegetable stock - 1 tsp smoked paprika - Fresh basil ### Directions 1. Heat oven to 200°C (390°F). 2. Halve the tomatoes, quarter and deseed the peppers, quarter the onion, and peel the garlic. 3. Place tomatoes, peppers, onion, and garlic on a large roasting tray. Drizzle with olive oil, season well, and roast for 35–40 minutes until soft and slightly charred. 4. Transfer to a blender with stock and paprika. Blend until smooth. 5. Reheat gently, adjust seasoning, and serve topped with fresh basil and a swirl of olive oil. --- ## Orange and yellow vegetables Carrots, sweet potatoes, butternut squash, yellow peppers, and corn contain high levels of alpha-carotene, beta-carotene, and beta-cryptoxanthin. Your body converts these 'carotenoids' into vitamin A, which is essential for skin, eye, reproductive health and your immune system. These orange and yellow vegetables also contain 'lutein' and 'zeaxanthin', compounds that accumulate in your retina and help protect against macular degeneration as you age. The naturally sweet flavour of these vegetables makes them particularly tasty when roasted, which concentrates their sugars and intensifies their flavour. ## Honey-roasted carrots and sweet potato Simple preparation that brings out their natural sweetness whilst preserving carotenoids. ### Ingredients (serves 4-6) - 500g (1.1 lb) carrots (peeled and halved lengthways) - 1 large sweet potato (peeled and cut into wedges) - 2 tbsp extra virgin olive oil - 1 tsp honey - 1 tsp ground cumin - fresh coriander ### Directions 1. Heat oven to 200°C (390°F). 2. Toss carrots and sweet potato with olive oil, honey, cumin, salt, and pepper. 3. Spread on a baking tray. Roast for 30–35 minutes, turning halfway, until tender and caramelised. 4. Scatter with fresh coriander before serving. --- ## Purple and blue vegetables Aubergines, purple cabbage, purple carrots, and purple potatoes contain anthocyanins — the same phytonutrient compound found in blueberries. These purple and blue pigments have strong anti-inflammatory and 'neuroprotective' properties, potentially supporting [brain health](https://www.alphabetguides.com/tag/brain-health/) and reducing cell damage from oxidative stress.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/32825684/?ref=alphabetguides.com) Research suggests anthocyanins may help maintain cognitive function as we age. Purple vegetables are unfortunately among the least consumed colour groups, with 88% of people failing to eat adequate amounts of them. Adding even one purple vegetable to your weekly meals can help address this gap. ## Warm red cabbage with apples A traditional flavour pairing that highlights anthocyanin-rich purple vegetables. ### Ingredients (serves 4-6) - 1 small red cabbage (finely shredded) - 2 apples (cored and sliced) - 1 red onion (sliced) - 2 tbsp extra virgin olive oil - 2 tbsp red wine vinegar - 1 tbsp honey - 2 cloves of garlic - 1 bay leaf ### Directions 1. Heat olive oil in a large pan. 2. Add the onion and cook for 5 minutes, until it is soft. 3. Add cabbage, apples, vinegar, honey, cloves, bay leaf, salt, and pepper. 4. Cover and cook gently for 40–50 minutes, stirring occasionally, until cabbage is tender. Add a splash of water if it becomes too dry. 5. Remove cloves and bay leaf before serving. 6. This dish keeps well in the fridge for up to 5 days and actually gets better over time. --- ## Green vegetables A fresh dish packed with green vegetables that works as a side or a light lunch. You can read more about the health benefits of [green vegetables](https://www.alphabetguides.com/superfood-leafy-greens/) in another article we've written. ![Courgette and pea fritter.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1607095591644-9f97a2099c92.jpeg) ## Courgette and pea fritters ### Ingredients - 2 medium courgettes - 150g (1 cup) frozen peas (defrosted) - 2 spring onions - 100g feta cheese - 2 eggs (beaten) - 75g (2.5 oz) plain flour - A handful of fresh mint and dill - EVOO for frying. ### Directions 1. Grate the courgettes, slice the spring onions, crumble the feta and chop the mint and dill. 2. Place grated courgette in a clean tea towel and squeeze out excess moisture. 3. Mix courgette, peas, spring onions, feta, eggs, flour, herbs, salt, and pepper in a bowl. 4. Heat 2 tablespoons of olive oil in a large frying pan. Drop spoonfuls of the mixture into the pan and flatten slightly. 5. Cook for 3–4 minutes each side until golden. 6. Drain on kitchen paper. Serve warm or room temperature. They go well with an arugula or spinach salad. --- ## White and pale vegetables White and pale vegetables — cauliflower, onions, garlic, turnips, parsnips, and mushrooms might seem less exciting than their colourful peers, but they're still nutritious. Cauliflower contains sulforaphane, a compound with potential anti-cancer properties. Onions and garlic ("[alliums](https://www.alphabetguides.com/3-healthiest-vegetables-around/)") provide organosulphur compounds and quercetin, supporting cardiovascular and immune health. Mushrooms, whilst technically fungi, not a vegetable, deserve mention here for their unique nutritional profile, including vitamin D (when exposed to sunlight) and immune-supporting compounds.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/30322118/?ref=alphabetguides.com) Don't overlook white vegetables — they're still part of the rainbow. ## Roasted cauliflower steaks with garlic A great way to serve cauliflower that maximises flavour and presentation. ### Ingredients (serves 4-6) - 1 large cauliflower (cut into 4 thick “steaks”) - 4 tbsp extra virgin olive oil - 4 garlic cloves (thinly sliced) - 1 tsp smoked paprika - Zest of 1 lemon - Fresh parsley (chopped) ### Directions 1. Heat oven to 220°C (400°F). 2. Brush the cauliflower steaks with half of the olive oil, then season them well with salt, pepper, and paprika. 3. Place on a baking tray and roast for 20 minutes. Flip, roast another 15–20 minutes until golden and tender. 4. Meanwhile, gently heat the remaining olive oil with garlic until fragrant. 5. Drizzle garlic oil over cauliflower steaks, scatter with lemon zest and parsley. Serve with crusty bread as a main course. --- ## Practical strategies for eating the rainbow _This post is for subscribers only._ ### How to Rest for Body Recomposition URL: https://www.alphabetguides.com/rest-and-body-composition/ Last updated: 2026-09-22T10:28:25.000Z summary - Muscle is built while you recover, not when you train. Sleep deprivation blunts growth hormone and testosterone, impeding muscle growth. - Regularly sleeping less than 6 hours a night impairs both muscle growth and fat loss by increasing your appetite and cravings for junk food. - Stubbornly high cortisol increases visceral fat and limits muscle growth, making stress management important. Rest days are the recovery periods between training sessions when the physiological processes that build muscle and adapt to exercise occur. This article explains the role of rest and recovery in body recomposition and how they support muscle repair and long-term progress. Even if training and nutrition are optimised, most of the actual changes occur during the recovery period, not during the training session itself. Resistance training doesn't build muscle directly — it damages and disrupts muscle tissue whilst triggering signals for adaptation. The actual construction of new muscle protein occurs during the hours and days following training, when your body is resting. So, insufficient rest and recovery between training sessions can hamper the adaptive response to training and your performance (and thus muscle growth).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/32179050/?ref=alphabetguides.com) For [body recomposition](https://www.alphabetguides.com/body-recomposition-series/), recovery is particularly important as you're attempting to build muscle in a suboptimal environment (because you are energy-restricted). So, maximising the quality and efficiency of recovery periods becomes even more important when energy is limited. ## Does Sleep Help Muscle Growth? Sleep represents the longest uninterrupted recovery period of your day. There is no other opportunity where you get 6–8 hours of complete and consecutive rest. Research consistently demonstrates that good [sleep is important for muscle growth](https://www.alphabetguides.com/sleep-for-muscle/). During sleep, particularly deep sleep, growth hormone peaks, creating a hormonal environment that favours growth.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/21550729/?ref=alphabetguides.com) Multiple studies have shown that protein consumed before [sleep](https://www.alphabetguides.com/eat-for-better-sleep/) is effectively digested and absorbed, and can stimulate muscle growth processes throughout the night. Sleep deprivation impairs muscle growth processes, even when you’re training and consuming enough protein.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/22330017/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/32078168/?ref=alphabetguides.com) It appears that sleep deprivation alters some of your hormones (like [testosterone](https://www.alphabetguides.com/testosterone-and-muscle-growth/), [cortisol](https://www.alphabetguides.com/what-is-cortisol/) and insulin-like growth factor 1) — which shifts your body towards breaking down muscle, rather than growing it. Practically, this means that sleep restriction, which means consistently having less than seven hours per night, will impair body recomposition efforts. So, sleep quality and duration should be considered alongside training and nutrition. ## Does Sleep Help with Fat Loss? Another “double-effect”. In addition to blunting muscle growth, sleep can also derail fat loss. Sleep restriction alters your appetite hormones, making you hungrier and more likely to adhere to calorie-restricted diets. Even just a single night of bad sleep can increase hunger. Over multiple days, these effects can compound, creating a drive to consume more food. This effect isn't trivial — persistent poor sleep has been shown to increase daily calorie intake by roughly 200–500 kcal through hunger alone.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/18564298/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/15583226/?ref=alphabetguides.com) More bad news. Sleep deprivation appears to increase preferences for [calorie-dense fatty, sugary and salty foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/). This isn’t a failure of willpower; it's how your brain responds to food cues. Poor sleep also has a second, independent effect on energy balance: it reduces how much you move. Sleep-deprived people tend to show lower non-exercise activity — walking less, fidgeting less — alongside reduced exercise performance, which can add up to a few hundred fewer calories burned per day. Much of this happens below conscious awareness, so you may not notice your activity level dropping. Poor sleep also appears to impair how efficiently your cells use fuel, blunting insulin sensitivity in a way that favours storing energy as fat rather than burning it. For body recomposition, which requires maintaining a moderate energy deficit consistently over weeks or months, poor sleep creates a dual problem: it simultaneously impairs the muscle-growth response to training and makes your diet more difficult to follow. Both effects undermine the goal of improving your body composition. Practically, prioritising seven to nine hours of [quality sleep](https://www.alphabetguides.com/fix-your-sleep-schedule/) per night is essential. This includes not just total sleep duration but also sleep consistency (regular bedtimes and wake times) and sleep quality (minimising interruptions). Treating sleep as a negotiable variable or something to sacrifice will be counterproductive to body recomposition goals. [SleepSleep is your body’s essential recovery period. It’s when your brain clears waste, your heart rests, your hormones and your brain reset themselves.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-bfe37560-1593-47dc-85ac-d5dbe67f3781.png)Alphabet Guides![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1529435022610-ccc7cab8499e-6fe8c6d7-8a78-4e40-a90b-1172c6fb8892.jpeg)](https://www.alphabetguides.com/tag/sleep/) --- ## Stress, Hormones and Energy Stress, be it psychological or physical, can also affect body recomposition, as it stimulates the release of certain hormones, like cortisol. Cortisol affects muscle in a few different ways.[\[7\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4315033/?ref=alphabetguides.com) 1. It increases muscle breakdown while also suppressing growth processes. 2. It blunts the effects of another hormone, insulin, which helps support muscle growth. Even with adequate protein intake, chronically elevated cortisol can impair muscle growth. 3. Another double effect: cortisol influences 'energy partitioning', increasing fat storage, particularly visceral fat, while blunting muscle growth. This is thought to happen as cortisol acts as a signal that (because of stress) energy needs to be conserved (to deal with the stress), and muscle is a nonessential luxury. While this might be a perfectly healthy evolutionary [response to stress](https://www.alphabetguides.com/what-is-cortisol/), it will directly undermine body recomposition efforts. Cortisol also drives cravings for calorie-dense, palatable foods specifically, which compounds its direct effects on fat storage — it's not just changing where energy goes, but how much you're inclined to eat in the first place.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/11070333/?ref=alphabetguides.com) In addition to everyday psychological stressors (like work, relationships, and financial worries), specific recomposition requirements like muscle soreness from training, hunger from energy deficits, and planning to meet nutritional targets can add extra stress. So you’re best keeping all forms of stress to a minimum. It's worth being honest about the limits of the evidence here: no specific stress-management technique has been directly shown to improve muscle growth — only exercise itself has that evidence behind it. Managing stress well may still indirectly support training performance and recovery, which is reason enough to prioritise it. ## The Stress–Sleep Doom Loop Poor sleep and chronic stress don't just act in parallel — they tend to make each other worse. Poor sleep and stress contribute to weight gain, which can bring on problems like sleep apnoea or low-level inflammation-driven discomfort. Those, in turn, disrupt sleep and elevate stress further, which drives further weight gain — and the cycle continues. But the encouraging part is that this works in reverse, too.[\[9\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC2951287/?ref=alphabetguides.com) Quality sleep and effective stress management don't just avoid the downward spiral — they actively amplify the benefits of your training and nutrition efforts. And unlike diet or training changes, which typically take weeks or months to show results, the mood, behavioural, and metabolic benefits of better rest tend to show up within days.[\[10\]](https://pubmed.ncbi.nlm.nih.gov/18517032/?ref=alphabetguides.com) ## Stress, Recovery and Recomposition When training stress exceeds your ability to recover, your performance will decline, and the adaptive response to training will be impaired. “Overtraining” or “Under-Recovery” manifests itself in a few ways: muscle soreness, weakness, mood changes, poor sleep or increased susceptibility to illness. One or more of these symptoms typically indicate that something isn’t working quite right under the hood. Poor recovery may not just pause, slow or impair progress — it may actually reverse it. The practical implication is clear: more training is not always better, especially if you’re on an energy-restricted diet.[\[11\]](https://pubmed.ncbi.nlm.nih.gov/24531430/?ref=alphabetguides.com) There is an optimal dose of training stimulus that maximises adaptation without exceeding recovery capacity. Exceeding this dose, even with the best intentions, may undermine results. #### 🚩Recovery Red Flags - < 6 hours or poor quality sleep last 2+ nights. - Moderate or severe muscle or joint soreness - Feeling exhausted, irritable, or unmotivated? - High emotional/psychological stress? - Obvious drop in strength/coordination. - Current/recent injury or illness - Sudden/Significant change in resting heart rate (10 bpm) --- ## Structuring Rest Around Training ### During training Recovery isn't just about days off — it also happens in the seconds and minutes within a session. Rest periods between sets sit at the centre of an ongoing debate: shorter rests (under 60 seconds) favour metabolic stress and [hormonal responses](https://www.alphabetguides.com/tag/hormones/), while longer rests (over two minutes) let you lift more weight and generate more mechanical tension — generally considered the more important driver of growth. The evidence is mixed on which wins out overall, so resting 1–3 minutes between sets is a sensible default; beyond that range, other training variables likely matter more.[\[12\]](https://pubmed.ncbi.nlm.nih.gov/26605807/?ref=alphabetguides.com)[\[13\]](https://pubmed.ncbi.nlm.nih.gov/28641044/?ref=alphabetguides.com) ### Between training sessions Between sessions, the standard minimum is around 48 hours of recovery per muscle group, though unfamiliar, high-intensity, or compound (multi-joint) exercise can require longer. You *don't* have to take 48 hours off training altogether — splitting sessions across different muscle groups lets you train more frequently while still respecting this window. Good muscle growth is achievable on as few as 2–3 non-consecutive sessions per week per muscle group, though more frequent training with shorter between-session gaps generally produces better results. How much recovery you personally need varies with training experience, age, nutrition, sleep, lifestyle, and genetics, so treat any fixed number as a starting point rather than a rule.[\[14\]](https://pubmed.ncbi.nlm.nih.gov/29345524/?ref=alphabetguides.com) ## Consistency Beats Intensity Body recomposition is inherently a moderate, sustained process rather than a rapid, magical transformation. The limited availability of energy, extra stress and some hormonal changes favour consistency and moderation over [crash diets](https://www.alphabetguides.com/crash-diet/) and German volume training. The person who achieves perfect adherence for two weeks before giving up will be worse off than the person who hits their targets 80% of the time but keeps it going for three months. Because many of these things that we’ve discussed interact with each other, you cannot optimise one thing (e.g., [strength training](https://www.alphabetguides.com/resistance-training-body-recomposition/)) while ignoring other things (sleep, nutrition, recovery, etc). It is also extremely difficult to offset one thing by increasing the other: for example, increasing the amount of training you are doing to counteract a bad diet. ## Active Recovery on Rest Days Complete rest has its place, but low-intensity movement on non-training days tends to speed recovery more effectively than doing nothing at all. [Walking](https://www.alphabetguides.com/why-walking-beats-running/), easy cycling, swimming, and yoga all improve blood flow, help clear metabolic waste, and maintain mobility. The key is keeping intensity genuinely low — a reasonable rule of thumb is to finish the session feeling no more tired than when you started. Other recovery methods (e.g., massage, cold-water immersion, sauna or heat therapy, contrast hydrotherapy, and compression garments) have reasonable evidence behind them too, but tend to be less effective and less cost-effective than simply moving.[\[15\]](https://pubmed.ncbi.nlm.nih.gov/29755363/?ref=alphabetguides.com) ## Practical considerations _This post is for subscribers only._ ### Body Recomposition Diet: What to Eat URL: https://www.alphabetguides.com/nutrition-and-body-recomposition/ Last updated: 2026-09-28T11:03:43.000Z summary - Protein intake of 1.6–2.4g per kg of body weight during calorie restriction preserves more lean muscle mass than lower protein intakes. - A 300–500 calorie daily deficit supports fat loss without impairing muscle growth or daily activity; larger deficits can undermine both. - Stored body fat can fuel the energy need for building new muscle; this aids recomposition, burning fat and building muscle at the same time. A diet for body recomposition balances sufficient protein intake, the right amount of calories, and nutrient timing to support muscle (maintenance or growth) while promoting fat loss. This article explains the practical dietary choices that best support recomposition. For body recomposition, good nutrition is crucial because you're asking your body to simultaneously support two processes: losing fat and either maintaining (or ideally, growing) muscle, which have traditionally been [viewed as incompatible](https://www.alphabetguides.com/body-recomposition-lose-fat-gain-muscle/). ## How much protein do you need for body recomposition? Your muscle isn't static. At every moment throughout the day, your muscles' proteins are being broken down and rebuilt in a continuous cycle called 'protein turnover'. After [resistance training](https://www.alphabetguides.com/minimalist-muscle-growth/), the process of muscle growth is elevated for up to 48 hours. However, when you’re in an energy deficit, it can potentially impair the growth stimulus. This is where protein intake becomes important, as it can help counteract the growth-suppressing effects of having less energy available. First and most obviously, protein supplies the 'amino acids' that serve as the building blocks of muscle. Your body cannot make muscle proteins without several amino acids (called “essential” amino acids), which can only come from your diet. Without adequate dietary protein, even the [strongest training stimulus](https://www.alphabetguides.com/back-to-basics-a-checklist-for-muscle-growth/) cannot produce meaningful muscle growth because the raw materials simply aren't there. Second, protein has a unique capacity to stimulate muscle growth directly. Certain amino acids, particularly leucine, activate the signalling pathways that stimulate muscle growth. This means protein intake doesn't just provide materials; it also triggers the construction process itself. Third, during an energy deficit, protein becomes increasingly important for preserving muscle. Research consistently shows that higher protein intakes (1.6–2.4 g/kg body mass) during caloric restriction result in greater preservation of fat-free mass compared to lower protein intakes, even when total weight loss is similar. A clear demonstration of [better body recomposition](https://www.alphabetguides.com/body-recomposition-series/).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/26817506/?ref=alphabetguides.com) Fourth, protein has the highest 'thermic effect' of all the macronutrients, meaning your body expends more energy digesting and processing protein compared to carbohydrates or fats. This modest but meaningful increase in energy expenditure can support fat loss goals. It has a lower “metabolisable” energy density than fat or carbohydrate, and it is more satiating — meaning it will help reduce hunger more effectively.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/17299116/?ref=alphabetguides.com) ## How many calories should you eat for body recomposition? Being in an energy deficit means your body must source energy from stored reserves, primarily your fat, but potentially also protein from your muscles. The question is, how large a deficit can you sustain whilst still [supporting muscle growth](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/)? While you can run a deficit and grow muscle, those exceeding 500 calories a day tend to impair your ability to preserve or grow muscle. Very large deficits (meeting less than half your energy needs) will likely turn on muscle breakdown processes, which not even [very high protein](https://www.alphabetguides.com/high-protein-diet/) and regular resistance training can offset. In fact, the dietary protein that you consume will end up being used for energy, rather than building muscle. And the net effect is that you’ll end up losing muscle over time. A moderate 300 to 500-calorie-a-day deficit seems like a sensible target. Smaller deficits will favour muscle growth but slow fat loss, whereas larger deficits will do the opposite. There is not really a standard, one-size-fits-all recommendation. ### A double effect Good news. Your stored fat can, to a degree, support the energy costs of building new muscle. Yes, you read that right: your muscles can use your own fat stores for energy. When you’re in an energy deficit, your body [breaks down stored fat](https://www.alphabetguides.com/weight-loss-fat-loss-faq/) to use for energy. If you're eating enough protein, resistance training, and the energy you're eating is not required elsewhere (for more important things), it can be used to build muscle. This is one of the reasons why those with more fat have greater potential for body recomposition and can potentially run larger energy deficits, because they can tap into their own fuel reserves in their fat. As your body becomes leaner, body recomposition becomes increasingly more difficult.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/36526940/?ref=alphabetguides.com) ### Other nutrients Whilst protein and total energy are the most important, there are a few other considerations. Carbohydrate intake, while not as critical as protein, can support training performance and recovery in between bouts of exercise. Dietary fat is also often overlooked. Inadequate amounts of dietary fat can impair [testosterone production](https://www.alphabetguides.com/testosterone-and-muscle-growth/), which in turn could impair muscle maintenance or growth. However, once the minimum requirements of fat (e.g., 0.5-0.8 g/kg body mass) and protein are met, the remaining calories from fat and carbohydrate can be adjusted to your personal preferences and training demands. Deficiencies in some micronutrients like vitamin D, zinc and magnesium can potentially impair body recomposition prospects. However, these are generally “threshold effects”, meaning that correcting deficiencies matters, but super-dosing won’t improve muscle growth or fat loss. ### A strategic foundation Nutrition for body recomposition isn't about following a perfect meal plan or hitting [precise macro targets](https://www.alphabetguides.com/muscle-fuel/) to the gram. It's about understanding the biological principles and creating a sustainable approach that provides adequate protein, maintains a moderate energy deficit, and supports training performance. Research consistently shows that higher protein intakes (over 1.6 g/kg body mass) combined with moderate energy deficits (\~ 500 kcal) and resistance training create an optimal environment for body recomposition.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/23739654/?ref=alphabetguides.com) In the final article of this series, we'll look at the last piece of the puzzle: rest. This includes recovery, sleep and stress. We’ll also round up all the principles and discuss their practical application. [Body Recomposition: A 5-Part SeriesA series of lessons on body recomposition, explaining how you can lose fat and gain muscle at the same time.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-9f6b9dd9-69eb-4c4e-954a-e517f19617a2.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1781800937305-5a2618f03ae4-fbf57f0c-7aec-49ab-8d96-fe3c520db0ba.jpeg)](https://www.alphabetguides.com/body-recomposition-series/) --- ## Frequently Asked Questions #### ****If I'm eating enough protein, can I eat very few calories and still build muscle?** No. Whilst adequate protein is essential, very large energy deficits (typically more than 500 calories below maintenance) create an environment that will impair muscle growth, and possibly lead to muscle wasting. #### ****Does the timing of protein intake matter for body recomposition?** Timing appears to matter, but less than your total daily intake. Ensuring you consume enough protein on your training days and the day after is particularly important. It is probably easier to hit your protein targets if you spread your protein intake throughout the day, rather than eating it all at once. #### ****I've been doing body recomposition for months, and progress has slowed dramatically. What's happening?** This is normal. Body recomposition becomes progressively more difficult as you become leaner and more trained. If you've lost substantial fat and gained noticeable muscle, you may have reached a point where further recomposition becomes more difficult. At this stage, it may be more efficient to have dedicated phases for either building muscle (“bulk”) or losing fat (“cut”) than to do both simultaneously. --- #### Sources 1. Longland TM et al.

Aim for at least 5 servings per week. - Chopped or crushed alliums contain "organosulphurs" that are associated with lower cancer risk and reduced blood pressure and cholesterol. - Leafy greens are rich in dietary nitrates, which the body converts to nitric oxide, which relaxes blood vessels and lowers blood pressure. While all vegetables contribute to health, research highlights three groups — cruciferous vegetables, leafy greens, and alliums — that are nutrient-dense and associated with strong health benefits. This article explains why these groups stand out and gives examples for each. There are definitely others, but including these three groups in your weekly rotation ensures you're getting a wide variety of health-protective plant nutrients. Each group contains unique “phytonutrients” (or “phytochemicals”) that work in different ways to support your health. Rather than focusing on individual 'superfoods', think of these three groups as foundational — what you want to prioritise. It's really not that hard to get all three into your diet. --- ## Group #1: Cruciferous vegetables Cruciferous vegetables include broccoli, cauliflower, Brussels sprouts, cabbage, kale, rocket, and bok choy. What makes them special? They're uniquely rich in 'glucosinolates' — which are sulphur-containing compounds that may reduce cancer risk (particularly for colorectal and lung cancers).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/17317210/?ref=alphabetguides.com) Aim for at least five servings of cruciferous vegetables a week. One serving equals approximately half a cup when cooked or one cup raw. A simple strategy: include one cruciferous vegetable in your evening meal 3-4 times per week. Cooking tip: Whilst raw cruciferous vegetables are nutritious, light cooking can make them easier to digest, taste better and actually improve nutritional content.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/33133569/?ref=alphabetguides.com) Avoid heavy cooking methods like boiling, stewing, roasting or microwaving at high power, as this reduces the availability of beneficial compounds. Instead, steam lightly, roast, or sauté in olive oil. ## Sautéed broccoli with garlic, chilli and lemon A simple, classic preparation that highlights the natural sweetness of cruciferous vegetables whilst incorporating some alliums. Serve as a side dish or as a main course on top of a bowl of hummus with some flatbread. ![Stir-fried broccoli with chili and onions in a pan.](https://images.unsplash.com/photo-1764850685848-2a70be195304?crop=entropy&cs=tinysrgb&fit=max&fm=jpg&ixid=M3wxMTc3M3wwfDF8c2VhcmNofDN8fFNhdXQlQzMlQTllZCUyMEJyb2Njb2xpJTIwd2l0aCUyMEdhcmxpYyUyQyUyMENoaWxsaSUyQ3xlbnwwfHx8fDE3ODI3NDEwMTd8MA&ixlib=rb-4.1.0&q=80&w=2000) ### Ingredients (serves 4-6) - 2 large heads of broccoli (cut into florets) - 4 garlic cloves (sliced) - 3 tbsp extra virgin olive oil - Zest & juice of 1 lemon - Red chilli flakes (optional) ### Directions 1. Bring a pan of water to the boil and cook the broccoli just until it starts to become tender (2-4 minutes). 2. Once cooked, allow the broccoli to drain for a few minutes to dry. 3. Whilst the broccoli is drying, lightly cook the garlic in the olive oil for a couple of minutes, then add the chilli flakes and cook for another minute or so. 4. Add the broccoli, lemon zest, salt, and pepper. 5. Cook in the flavoured oil for 4–6 minutes until the broccoli is hot and mixed well with the other flavourings. --- ## Group #2: Alliums Garlic, onions, leeks, shallots, and chives make up the allium family. These vegetables have been valued for medicinal purposes for millennia. Research suggests allium vegetables may help reduce the risk of certain cancers, particularly stomach and colorectal cancers, whilst also supporting cardiovascular health.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/25586902/?ref=alphabetguides.com) Their health benefits come primarily from 'organosulphur' compounds — the same ones that are responsible for their pungent smell. These compounds are activated when the vegetables are chopped, crushed, or chewed. Garlic, in particular, has been studied for its potential to lower blood pressure and cholesterol in people with elevated levels.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/32010325/?ref=alphabetguides.com) Unlike most other vegetable groups, alliums work well to improve the flavour of other ingredients rather than the main vegetables. Many dishes start with cooking onions and garlic in olive oil. You don't need large quantities — a few cloves of garlic or half an onion per person will add both flavour and health benefits to your meal. Use alliums generously in your cooking. Don’t skip starting savoury stews or soups with gently cooked onions and garlic. Add raw red onion to salads for a sharp bite — soak them in cold water after slicing to take the edge off, if you don’t like the raw flavour. Scatter fresh chives over soups or roasted vegetables. ## French onion soup A classic French soup that uses the alliums as the main ingredient rather than an accompaniment or a flavouring. ![French onion soup.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1589563766992-49797b1148a2.jpeg) ### Ingredients (serves 4-6) - 6-8 medium to large onions (thinly sliced) - 4 garlic cloves (minced) - 3 tbsp extra virgin olive oil - 1.5 litres vegetable stock - 2 bay leaves - 1 tsp thyme - 2 tbsp red wine vinegar - Wholegrain bread and cheese for topping (optional) ### Directions 1. Heat the olive oil in a large pot. Add onions and cook slowly over medium-low heat for 30–40 minutes, stirring occasionally, until deeply caramelised and golden brown. 2. The long, slow cooking transforms onions from sharp to sweet, concentrating their beneficial compounds whilst developing incredible flavour. 3. Add garlic, cook for another 2–3 minutes. Add stock, bay leaves, thyme, and vinegar. 4. Simmer for 20 minutes until the vegetables are soft and it's thickened. 5. Season well. Serve in bowls topped with toasted wholegrain bread and a sprinkle of cheese if desired. --- ## Group #3: Leafy greens Spinach, kale, Swiss chard, lettuce, watercress, and rocket form this group of vegetables. Regular consumption of leafy greens is strongly associated with better cardiovascular health.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/27540481/?ref=alphabetguides.com) [Leafy greens](https://www.alphabetguides.com/superfood-leafy-greens/) are particularly rich in dietary nitrates, which your body converts to nitric oxide. This compound helps relax and widen blood vessels, potentially lowering blood pressure. They're also excellent sources of folate, vitamin K, lutein, and chlorophyll — nutrients that support everything from blood clotting to eye health. The deep colour of dark leafy greens generally indicates a higher concentration of some beneficial compounds. The darker the leaves, generally, the more nutrient-dense they are. Rocket and watercress add strong peppery flavours, whilst chard and spinach offer milder flavours that work well in lighter flavoured dishes.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/35740055/?ref=alphabetguides.com) Aim for one cup of leafy greens a day. This could be a [side salad](https://www.alphabetguides.com/mediterranean-salads/) at lunch, spinach wilted into your eggs at breakfast, or rocket tossed through pasta at dinner. Use them as a seasoning or a base. Fresh, frozen, or even tinned (like spinach) all count — choose whatever makes regular consumption easiest ## Garlic sautéed spinach Ready in five minutes, this is a classic go-to leafy green side dish with alliums. ### Ingredients - 300g (10 cups) fresh spinach (washed) - 2 garlic cloves (thinly sliced) - 2 tbsp extra virgin olive oil - A pinch of nutmeg - A squeeze of lemon juice ### Directions 1. Heat olive oil in a large pan over medium heat. Add garlic and cook for 1 minute until fragrant but not browned. 2. Add spinach in batches, stirring as it wilts. 3. Once all spinach is wilted (about 3-4 minutes), season with nutmeg, salt, pepper, and lemon juice. Serve immediately. 4. Frozen spinach works equally well for this recipe. Defrost, squeeze out excess water, then proceed with the garlic step. --- ## Action plan This week, shop for one vegetable from each group. Try one of the recipes, maybe as a starter, light lunch or as a side dish for dinner. These three groups aren't meant to replace other vegetables — tomatoes, peppers, courgettes, and aubergines all have their place. Think of cruciferous vegetables, leafy greens, and alliums as your core rotation, with other vegetables adding [variety](https://www.alphabetguides.com/eat-the-seasons-the-seasonality-rule/) and [colour](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/). Most of the vegetables found in these groups are versatile. You can prepare them simply (steamed, sautéed, raw) or incorporate them into more complex dishes (soups, stews, gratins). Find dishes you genuinely enjoy eating (and enjoy making), so eating these vegetables becomes effortless rather than a chore. --- #### Sources 1. Higdon JV et al.

The Nordic diet is based on the traditional eating habits of Scandinavian countries (i.e., Denmark, Sweden, Finland, Iceland, and Norway). It aims to promote health, support the environment and preserve Nordic food traditions with regional, seasonal and sustainably produced foods native to Scandinavia. It is another [plant-slant diet](https://www.alphabetguides.com/tag/plant-based/), which includes vegetables, fruits, berries (particularly wild berries such as lingonberries, blueberries, and cloudberries), root vegetables, legumes, and whole grains (especially rye, barley, and oats). [Rapeseed (or ‘canola’) oil](https://www.alphabetguides.com/canola-vs-olive-oil/) is the main source of fat as it’s rich in monounsaturated fats and omega-3 fats. Rapeseed oil offers a healthy option that is *comparable* to olive oil. Fish and seafood, particularly [fatty fish](https://www.alphabetguides.com/superfood-oily-fish/) rich in omega-3 fatty acids like salmon, herring, and mackerel, feature heavily. While game and poultry appear in moderate amounts, it limits red meat, processed meats, added sugars, and alcohol.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/22761599/?ref=alphabetguides.com)[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC10271429/?ref=alphabetguides.com) The diet has a high fibre content from whole grains and vegetables, which is good for your gut health and [cardiometabolic health](https://www.alphabetguides.com/tag/heart-health/). Omega-3 fatty acids from seafood support cardiovascular health and help keep inflammation under control, while unprocessed ‘complex’ carbohydrates help control blood sugar and body weight. The diet’s colourful berries and vegetables provide antioxidants and micronutrients that protect your cells. And outside of the nutritional content of the diet, other ‘healthy’ behaviours are encouraged, like foraging, buying locally and preserving foods. --- ## Example foods and dishes - **Breakfast:** - Rye bread with smoked salmon, dill, & quark - Porridge with lingonberries & crushed almonds - **Lunch:** - Dark rye, open-faced sandwich with herring & beetroot - Barley soup with root veg & whole grain crispbread - **Snack:** - Crispbread with cottage cheese & cucumber - Fresh berries & hazelnuts - **Dinner:** - Roast cod, boiled new potatoes, cabbage, & dill sauce - Game meat with roasted root veg & lingonberry sauce - **Dessert:** Baked apple with [oats](https://www.alphabetguides.com/oats-health-benefits/) - **Drinks:** Black coffee, herbal tea --- ## Pros Several studies have shown that the diet reduces cardiovascular disease, stroke risk, and type 2 diabetes for those who follow it. Reduced blood pressure and LDL cholesterol are also reported, supporting cardiometabolic health. Studies have also shown modest but sustainable reductions in [body weight and body fat](https://www.alphabetguides.com/tag/fat-loss/) in people who are overweight or obese.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/29945632/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/36008559/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/23792909/?ref=alphabetguides.com) The diet has a great nutritional profile, having balanced macronutrient intake whilst meeting or exceeding recommended intakes for all major vitamins and minerals. Detailed dietary analyses have confirmed minimal risk of nutrient deficiencies due to its emphasis on nutrient-dense whole foods.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/22761599/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/24257725/?ref=alphabetguides.com) ## Cons While the diet seems to work in the Nordic countries, its generalisability to other regions presents challenges. Research on the diet predominantly involves Scandinavians, leaving real-world adherence and effectiveness in non-Nordic countries and people less certain. Familiarity with traditional Nordic foods and cooking methods makes the diet easier to follow, but it may not work as well outside these regions.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/29945632/?ref=alphabetguides.com) Practical barriers stopping people from following the diet include the availability or cost of *some* of the foods outside of Scandinavia (e.g., rapeseed oil, rye, wild game, Nordic berries). The emphasis on ‘[seasonal eating](https://www.alphabetguides.com/eat-the-seasons-the-seasonality-rule/)’ makes it even more difficult to follow to the letter.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/23792909/?ref=alphabetguides.com) So, adapting the diet outside the Nordic regions requires thoughtful substitution of locally available equivalents for traditional Nordic ingredients; this, in turn, may alter the diet's nutritional profile or palatability for people unfamiliar with Nordic culinary traditions. In other words, by trying to adapt the diet, you may lose what makes it unique in the first place. --- ## Bottom Line The Nordic diet represents a nutritious, safe eating pattern with demonstrated health benefits. Its sustainability and high adherence among Nordic people are well-established, though its applicability and long-term effectiveness in other people are lacking. --- ## Overall Score: **★★★★☆** - Health Benefits: **★★★★☆** - Nutrition: **★★★★★** - Weight Control: **★★★★☆** - Ease to Follow: **★★★☆☆** - Safety Profile: **★★★★★** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

Losing fat and gaining muscle simultaneously (called 'body recomposition') requires a coordinated approach to nutrition and [resistance training](https://www.alphabetguides.com/resistance-training-beginners/). This article outlines practical, evidence-based strategies to achieve both goals together at the same time. When most people think about changing their bodies, they’ll focus on the [number on the scale](https://www.alphabetguides.com/beyond-the-scale/). But that single number obscures something far more important: what your body is actually made of. Body recomposition, which involves simultaneously reducing fat and increasing muscle, represents a different approach to defining what constitutes a “healthy” physical change. Rather than simply making your body smaller, recomposition focuses on improving what your body is made of. ## Beyond body weight: body composition Your total body weight consists of many different parts: fat mass, skeletal muscle, organs, bones, nerves, water, and connective tissue, to name a few. When you step on the scale, you're measuring all of these components together at the same time. Whereas body composition refers to how “much” of each of these different tissues you have, and (usually) their 'relative' proportions to each other (or sometimes your relative to your height). The most commonly used body composition measure is the ratio of fat you have relative to your fat-free mass (i.e., muscle, bone, and other non-fat tissues). But many others are used as well. The distinction between body weight and body composition matters. Two people of the same height and weight can look completely different and have vastly different health profiles depending on their body composition. The person with more muscle mass and less fat generally has better health prospects, greater functional capacity, and lower disease risk. ### A contradiction For years, conventional wisdom has suggested that building muscle and losing fat are mutually exclusive. The reasoning seemed logical: building new tissue (of any type) requires excess energy (a 'calorie surplus'), whilst burning fat requires an energy deficit. How could you possibly do both at once? This apparent contradiction comes from viewing the body as a single, unified system with one energy system responsible for supplying and regulating all tissues in the exact same way. If only it were that simple. In reality, muscle and fat are independently controlled and respond to different things. If this were false, you would simply not be able to grow muscle in an energy deficit (but you can!).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/24595305/?ref=alphabetguides.com) ## Muscle vs. fat Fat tissue (or 'adipose tissue') and muscle tissue are not simply passive storage depots. Both are metabolically active, independent organs with their own hardwired systems in place. Fat tissue stores energy primarily as triglycerides and releases them when you need energy. Muscle tissue is composed of proteins that contract to produce force and allow you to move around. These tissues respond to different hormonal signals and operate on different timescales. For example, fat breakdown can occur very quickly when energy is needed. Whereas building muscle is slower and requires specific “stimuli” and conditions for it to grow, and, unlike fat, it is not completely dependent on the amount of energy you have available. This independence means that, under the right conditions, you can break down fat for energy while at the same time building muscle. ## Protein: a structural requirement Here's a crucial point: whilst energy (or “calories”) and building materials (“dietary proteins”) are both necessary for life, they serve fundamentally different purposes. Your body can use fat, carbohydrate, or protein for energy, but only protein can provide the material required to build new muscle tissue.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/11255140/?ref=alphabetguides.com) Your body cannot make muscle proteins from fat or carbohydrate — they can only come from dietary protein. This is why adequate [protein intake](https://www.alphabetguides.com/nutrition-and-body-recomposition/) is essential for body recomposition, even when total calories are lowered to promote fat loss. When protein intake is sufficient during an energy deficit, your body can maintain or even increase the rate at which it builds new muscle. It can do this while breaking down stored fat to provide energy needs (which includes building muscle itself).[\[3\]](https://pubmed.ncbi.nlm.nih.gov/23739654/?ref=alphabetguides.com) --- ## The energy deficit Going from an energy surplus or balance to an energy deficit is better understood as a phase or range transition rather than an on-off switch. When you consume fewer calories than you expend, you've created a situation where your body must access stored energy to keep it going. But this doesn't automatically mean you’ll start breaking down more of your muscle to use for energy. Your body has a choice between two major energy reserves: your fat tissue and the protein in your muscles. Which one it chooses to use depends on several factors, like how large the energy deficit is, your current energy needs, hormones, your physical activity level, and the availability of other nutrients in your body. Moderate energy deficits combined with resistance training and an adequate supply of dietary protein can lead to the body preferentially using fat for energy while maintaining (or even building) muscle.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/21558571/?ref=alphabetguides.com) ## “Energy partitioning”: where does it all go? The concept that ties this all together is energy or nutrient 'partitioning'. This is basically where your body decides to send incoming energy and nutrients. Will they be metabolised for energy straightaway? Will they be stored? If so, where will they be stored? In your liver, in your fat tissue or elsewhere? Or should they be used to build new muscle tissue? The answer to these questions is determined by a combination of different things (like your hormones, genetics, environment, and other [lifestyle choices](https://www.alphabetguides.com/rest-and-body-composition/)). When you combine resistance training with an adequate supply of dietary protein and a (moderate) calorie deficit, you are essentially instructing your body to send nutrients towards your muscles. You are also asking stored fat to be broken down and used for energy. ## Who can achieve body recomposition? The [potential for body recomposition](https://www.alphabetguides.com/body-recomposition-series/) isn't the same across all people or circumstances. Those who are new to exercise and resistance training will likely have greater room to increase their muscle mass (in relative terms). Likewise, those who have larger amounts of body fat have greater potential to change their body composition. Age and health status will also affect the amount of 'recomposition' you can achieve. However, this doesn't mean that those who are older, leaner, have certain diseases, have more muscle or are already well-trained can’t achieve body recomposition — because they can.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/39290563/?ref=alphabetguides.com) Although still possible, there's probably a point where it becomes more “efficient” (i.e., quicker, easier and/or better results) to dedicate specific periods to building muscle (in an energy surplus) orto [lose fat](https://www.alphabetguides.com/weight-loss-fat-loss-faq/) (in an energy deficit) than trying to achieve both at the same time. Some people may also just want to focus primarily on one component of recomposition. For example, you may want to build a lot of muscle while losing only a little fat, or you may want to lose a lot of fat while maintaining your muscle mass. You’ll need a specific plan for that.

Avoid. The ‘Standard American Diet’, sometimes called the ‘Western Pattern Diet’, is the most common eating pattern of the people in North America, Europe and Australia. It is also increasing in urban areas all around the world.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/15699220/?ref=alphabetguides.com) The main foods in this diet are processed and [ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/), red and processed meats, refined grains, sugars, unhealthy fats, alcohol and sugary drinks. It is generally low in [fruit and vegetables](https://www.alphabetguides.com/tag/plant-based/), whole grains, legumes, and dietary fibre.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/37375654/?ref=alphabetguides.com) The diet emerged fairly recently (after world war 2) through industrialisation, new food processing technology, food marketing, globalisation, and changes in people’s lifestyles (which prioritise convenience). Fast food, packaged food, microwave food, sugary cereals, reconstituted meat products, sodas and energy drinks are common examples. These foods typically contain a lot of calories but few nutrients. They are designed for convenience, shelf life and taste, and little else. The diet’s popularity (unsurprisingly) coincided with dramatic increases in obesity, diabetes, cardiovascular disease and cancer. It is one of today’s most significant challenges for public health.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31695465/?ref=alphabetguides.com) --- ## Example foods and dishes - **Breakfast:** - Bacon, eggs, hash browns, white toast with butter, and orange juice - Pancakes with butter & syrup, sausage, & coffee with cream and sugar - **Lunch:** - Cheeseburger with fries - Fried chicken sandwich with coleslaw - **Snack:** - Potato chips with ranch dip - Cheese and crackers with deli meat - **Dinner:** - Steak with baked potato (butter, sour cream, bacon), white roll with butter - Spaghetti with meatballs, garlic bread, and Caesar salad - **Dessert:** Apple pie with vanilla ice cream - **Drinks:** Fruit juice, soda, beer --- ## Pros The [Western diet's](https://www.alphabetguides.com/fix-the-western-diet/) only advantages relate to convenience and accessibility rather than health. It offers unmatched convenience. The ready-to-eat, ready-to-heat foods require little prep time or cooking skills. Fast food restaurants, convenience stores, and packaged foods are common in the West, making adoption of the diet easy and, unfortunately, the default choice. The low ‘cost per calorie’ of [processed foods](https://www.alphabetguides.com/ultra-processed-food-diet/) helps [their popularity](https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/). This makes the diet more appealing to poorer people and those with little access to fresh foods. The foods that are widely consumed in this diet are purposefully designed to be tasty (or ‘hyperpalatable’).[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31695465/?ref=alphabetguides.com) They contain precise combinations of fat, sugar, salt and strong flavourings that provide immediate (but short-lived) satisfaction. Western dietary patterns align with common social norms, workplace meals, and family eating habits in many societies; they’re embedded in nearly every aspect of modern life. ## Cons Numerous high-quality studies have shown that the Western diet is associated with [cardiovascular disease](https://www.alphabetguides.com/tag/heart-health/), hypertension, stroke, type 2 diabetes, obesity, certain cancers (particularly colorectal, breast, and prostate), non-alcoholic fatty liver disease, and lower life expectancy; it also increases inflammation, ‘oxidative stress’, and metabolic disease.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/37375654/?ref=alphabetguides.com) The Western diet pattern doesn’t provide enough dietary fibre, several vitamins (particularly vitamins D, E, folate), minerals (magnesium, potassium), antioxidants, and ‘phytonutrients’ (from plants). It delivers excessive saturated fats, [added sugars](https://www.alphabetguides.com/reduce-sugar-intake/), sodium, and “empty” calories. Weight gain and obesity are inevitable.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/33671569/?ref=alphabetguides.com) The diet's high energy density, poor satiety, and ‘hyperpalatability’ promote overconsumption of food. Studies consistently link Western dietary patterns to weight gain, increased [body fat](https://www.alphabetguides.com/tag/fat-loss/), and difficulty maintaining a healthy weight. Mental health issues and cognitive decline are also associated with the diet. People who follow the diet for a long-time have increased ‘[brain-ageing](https://www.alphabetguides.com/tag/brain-health/)’ and dementia risk. It disrupts the gut microbiome, reducing the beneficial bacterial diversity and promoting imbalances that are linked to inflammation and metabolic disease.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/33671569/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/33329193/?ref=alphabetguides.com) Western diet significantly reduces your life expectancy compared to healthier alternatives. So, changing from the Western diet to a [healthier one](https://www.alphabetguides.com/tag/mediterraneandiet/) could add several years to your life; generally, the earlier the change takes place, the better.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/35134067/?ref=alphabetguides.com) ## Bottom Line The Western diet represents a cautionary tale of modern-day ‘food systems’. Prioritising convenience and accessibility, it actively undermines public health. There is overwhelming evidence linking the Western dietary pattern to several common chronic diseases, obesity, reduced lifespan and healthspan. It offers no health benefits beyond convenience and how easy it is to follow. --- ## Overall Score: **★★☆☆☆** - Health Benefits: **★☆☆☆☆** - Nutrition: **★★☆☆☆** - Weight Control: **★☆☆☆☆** - Ease to Follow: **★★★★☆** - Safety Profile: **★★☆☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

Even a 10% reduction in them represents a meaningful, clinically relevant health improvement. - Flexible diets outperform rigid rules for long-term adherence; small, sustainable swaps matter more than dramatic overhauls. - Batch-cook whole-food staples, keep fruit and cut veg visible and ready, and build a default shopping list of minimally processed foods. Avoiding [ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-diet/) means prioritising whole foods, cooking from scratch, and choosing products with just a few natural ingredients. This article covers practical approaches to reducing exposure to UPFs. As UPF consumption increased globally, researchers began investigating potential health concerns associated with it. Over the past decade, evidence has accumulated from around the world, and [the findings aren't good](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/). Reducing UPF intake doesn't require perfection or complete elimination. Small, sustainable changes often matter more than dramatic overhauls that prove impossible to maintain. The goal shouldn’t be about creating a new source of stress or guilt around eating, but rather finding realistic ways to shift toward eating less UPF where practical and sustainable. Time, budget, cooking skills, access to certain stores or markets, and the type of household you’re in all influence what's achievable. What works for one person may not work for another. What this article aims to do is give you options, not diktats. Choose what fits your life and personal circumstances. Before changing anything, audit your current eating habits. What UPFs appear regularly in your diet? When do you reach for them? Why do you eat them — convenience, comfort, time, or affordability? Understanding your habits helps identify the most effective changes. You may not be looking for an overhaul at first; rather, look for quick, easy, sustainable fixes first. Pick the low-hanging fruit. ## Healthier Alternatives to Common Ultra-Processed Foods ### Breakfast Most [modern breakfast](https://www.alphabetguides.com/western-diet/) staples are UPFs: sugar-sweetened cereals, breakfast bars, instant oatmeal, and packaged processed breads and pastries. Simple swaps include eating plain steel-cut oats with fruit and nuts, eggs or nut butters on whole-grain toast, and plain yoghurt with fresh or frozen fruits. Think about quick, healthy options for busy weekday mornings. Batch-preparing breakfasts on weekends can help mornings during the week. Make a large batch of [plain oatmeal](https://www.alphabetguides.com/oats-health-benefits/), portion it, and reheat as needed. Make overnight oats the night before and eat them cold the next day. Hard-boil a pack of eggs. Prep fruit and keep it in the fridge so it's grab-and-go ready. ### Lunch and Dinner Ready meals, frozen pizza, instant noodles, and heavily processed meat products are the mainstays of lunches and dinners. Replacing all of these may be too difficult, so start with one or two meals a week. A few simple meals, cooked regularly, can reduce decision fatigue (and cooking time as you get better at making them). A basic template might be: protein + vegetable + starch. Grilled chicken, roast vegetables, and rice. Baked fish, steamed broccoli, and potatoes. Beans, greens, and bread. None of these requires advanced cooking skills. Most take 20-30 minutes from start to finish. Research suggests that even modest improvements in your cooking skills are linked to better diets. Batch cooking is a great tip. Make large portions and freeze half. Cook double the rice, and refrigerate the leftover for later in the week. Roast a whole chicken; use leftovers for subsequent meals. Recreate the convenience UPFs. They [became popular](https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/) for a reason.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/31602753/?ref=alphabetguides.com) ### Snacks Packaged snacks represent a major UPF category: chips, cookies, crackers, chocolate, candy, and cakes. They’re probably the number one source of excess calories for most people. So prioritise alternatives to these. Minimally processed snack options include fresh fruit, nuts, plain yoghurt, hard cheese, boiled eggs, vegetables with hummus, or popcorn you pop yourself. They only require a bit more effort to prepare. Preparation makes the difference. Wash and cut vegetables when you get home from shopping. Portion nuts into small containers. Keep fruit visible and accessible. When minimally processed options are convenient and visible, you'll probably be more likely to choose them more often. ### Beverages Soft drinks, energy drinks, flavoured coffees with multiple additives, and sweetened fruit drinks all contribute to people’s UPF intake. They also add sugar and “empty calories” without providing satiety or any nutrient value to your diet. Water remains the simplest (and cheapest) alternative. If plain water feels boring, try infusing it with fruits or herbs. Unsweetened tea and coffee are also fine. Sparkling water offers the fizz without additives. For occasional sweet drinks, studies indicate that even partially replacing sugary beverages with water improves various health markers. You don't have to eliminate soda to start seeing the benefits. Reducing the overall amount that you drink is what matters at first.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/39207876/?ref=alphabetguides.com) ## How to avoid ultra-processed foods ### Build a default shopping list Create a standard grocery list prioritising minimally processed basics first: vegetables, fruits, proteins, whole grains, dairy, eggs, legumes, nuts, and simple cooking ingredients. Shop primarily from this list, adding extras intentionally rather than impulsively. ### Eat healthy convenience foods Not all 'convenient foods' are UPFs. Buying pre-washed [salad greens](https://www.alphabetguides.com/superfood-leafy-greens/), frozen vegetables, canned beans, canned tomatoes, canned fish, rotisserie chicken, pre-cut vegetables, and frozen fruit offers convenience without the industrial processing. These items cost more than raw ingredients, but less than ready meals (when you correct for nutrient content and the downstream healthcare costs). However, they reduce preparation time. Using them strategically makes cooking from basic ingredients more manageable on busy days. ### Master a few simple recipes You don't need extensive cooking skills. Five to ten simple recipes you can make confidently cover most situations. Focus on flexible formulas rather than precise recipes: stir-fries with varying vegetables and proteins, simple pasta dishes with different vegetables, basic grain bowls, sheet pan meals. ### Plan flexibly Rigid meal plans often fail when life inevitably disrupts them. Instead, keep your plan flexible. Shop for ingredients that allow multiple quick meal options. Keep backup ingredients for when plans change. Accept that some days require more convenience than others. Research on dietary adherence consistently finds that flexible approaches outperform rigid rules over time. Don’t let perfect be the enemy of good.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/10336790/?ref=alphabetguides.com) ### Prep in small batches Full-day meal prep marathons work for some people, but aren’t suitable for others. Consider smaller, more frequent prep sessions instead. Spend 15 minutes washing and cutting vegetables while cooking a large batch of rice, quinoa or other whole grains. These (relatively) small investments create convenience throughout the week. ### Read labels selectively You don't need to scrutinise every food label, but checking packaged items occasionally builds awareness. Long ingredient lists with unfamiliar terms are usually a sign of UPFs. Simple ingredient lists with recognisable foods suggest less processing. Over time, you will get quicker with practice at recognising UPFs. So be patient to start with. You'll come to learn which brands or products to avoid and which offer minimally processed alternatives. ### Use moderation Occasional consumption of UPFs can fit within a healthy diet. The concern around UPFs centres on their dominating your intake. Some situations naturally involve UPFs: social occasions, travel, celebrations, or times of unusual stress. These occasions don't negate other efforts. Consistency beats perfection. If UPFs currently provide 60% of your calories, reducing that to 40% represents a meaningful improvement. Dropping further to 20% offers additional benefits. But zero isn't the necessary goal. The pursuit of trying to reach it might create unnecessary stress and derail efforts. --- ## Bottom Line We’ve looked at UPFs from multiple angles: how they're [defined and identified](https://www.alphabetguides.com/ultra-processed-food-an-introduction/), the forces driving their consumption, their health effects, and practical approaches to reducing intake. Several themes have emerged across these articles. First, [UPFs became popular](https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/) through the genuine advantages they offer, not just through poor choices or corporate manipulation. They solved real problems around convenience, financial cost, and availability. Second, they have led to other ‘costs’, specifically to people's health. The consistency of the outcomes across different people and links to different [health conditions](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/) warrants taking their impact on your health seriously. Third, reducing UPF intake requires more than willpower or knowledge. It requires addressing practical barriers, building sustainable habits, and recognising that perfect adherence isn't necessary or realistic for most people, not in our current food environment anyway. UPFs will likely remain part of the food system for some time to come. The question isn't whether they exist, but how much space they occupy in your diet. By understanding what they are and some practical strategies to reduce them, we hope people can shift the balance in directions that support their wellbeing while realising the real-world constraints. --- #### Sources 1.

The grade of olive oil is important. - One to two tablespoons a day is a good target. Replacing fats such as butter or margarine with it is better than simply adding it. Olive oil is a plant-based fat known for its beneficial effects on cardiovascular and metabolic health. This article reviews the main health benefits of olive oil, including its role in the [Mediterranean diet](https://www.alphabetguides.com/mediterranean-diet-review/). It comes in a few different “grades”: extra virgin olive oil (EVOO), virgin olive oil, and refined olive oil. The difference between the grades relates to the processing method used to extract the oil, the acidity level, and (most importantly) its 'polyphenol' content. EVOO is the least processed and contains the highest levels of beneficial compounds. Unlike most other cooking oils (which are really just refined fats), EVOO provides a combination of healthy fatty acids and antioxidants. This unique combination is what sets it apart (nutritionally) from other fats. It also tastes great. While olive oil has been a dietary staple in Mediterranean countries for thousands of years, the scientific evidence for its health benefits has only emerged over the past few decades. ## What are the health benefits of eating olive oil? ### Monounsaturated fats and heart health Olive oil is composed primarily (around 75%) of oleic acid, a monounsaturated fatty acid ('MUFA'). Unlike saturated fats, which tend to raise LDL ("bad") cholesterol, or highly processed polyunsaturated oils ('PUFA'), oleic acid has neutral-to-beneficial effects on your blood lipid profile. Replacing saturated fats with olive oil tends to improve cholesterol ratios without lowering the "good" HDL cholesterol. However, the cardiovascular benefits of olive oil extend far beyond its fatty acid profile.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/3132035/?ref=alphabetguides.com) ### Polyphenols: olive oil's most powerful compounds The most distinctive compounds in EVOO are 'polyphenols'. These are plant compounds ("phytonutrients") that have antioxidant and anti-inflammatory properties. The main polyphenols include: hydroxytyrosol, tyrosol, oleuropein, oleocanthal, and oleacein. Polyphenol content varies significantly between different types of olive oil. EVOO contains around 100-500 mg per kg, while refined olive oils contain almost none. So not all olive oils are equal when it comes to their health benefits. Processing, storage time, and heat can all reduce polyphenol levels as well. So, why are polyphenols so good for health? They reduce “oxidative stress” (which is damage from free radicals to your cells) and help control inflammation. Studies have shown that the high-polyphenol olive oil reduces markers of oxidation and inflammation more effectively than low-polyphenol versions, even when the fat composition of the oil was the same.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/40749711/?ref=alphabetguides.com) ## Is extra virgin olive oil good for your heart? The cardiovascular benefits of EVOO are proven. Researchers found that those consuming the most olive oil lowered their risk of cardiovascular disease by over a third. For every 10 grams a day increase in EVOO per day, cardiovascular disease risk was reduced by 10%.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/24886626/?ref=alphabetguides.com) A study in people with high cardiovascular disease risk found that a [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/) supplemented with EVOO had a reduced chance of major "cardiovascular events" (heart attack, stroke, or cardiovascular death) by around a third compared to a control diet over five years. The olive oil group received about one litre per week to use freely in their household.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/29897866/?ref=alphabetguides.com) Similar results have also been shown for reducing type 2 diabetes, cancer risk, respiratory disease risk, and improving brain health. Researchers reported that replacing 10 grams a day of margarine, butter, mayonnaise and/or other dairy fats with 10 grams of olive oil reduced all-cause mortality.[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8851878/?ref=alphabetguides.com) ### How? The polyphenols in EVOO lower LDL cholesterol oxidation, which is a key step in the development of atherosclerosis ('blocked arteries': a precursor to cardiovascular diseases). They also improve “endothelial function” (the ability of blood vessels to relax and dilate properly, and control blood pressure), and they reduce inflammation as well. The compound 'oleocanthal' has anti-inflammatory effects similar to ibuprofen, though at much lower potency. Regular consumption provides a gentle, ongoing anti-inflammatory effect that may contribute to reduced disease risk, [healthy ageing](https://www.alphabetguides.com/andropause/) and other diseases caused by inflammation.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/16136122/?ref=alphabetguides.com) ### Beyond the heart: brain, blood sugar and cancer risk Beyond cardiovascular health, olive oil also provides vitamin E, which has been associated with better cognitive function in older adults, lower risk of depression, and improved blood sugar control. Some research suggests protective effects against certain cancers, though the evidence is not as strong.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/35277015/?ref=alphabetguides.com) A tablespoon (15ml) of olive oil provides about 120 calories, 14g of fat (mostly monounsaturated), 2mg of vitamin E (13% of daily needs), and varying amounts of polyphenols depending on quality. --- ## Is a tablespoon of olive oil a day good for you? The evidence suggests that 15-30g per day (1-2 tablespoons) provides meaningful health benefits. This aligns with typical [Mediterranean dietary patterns](https://www.alphabetguides.com/mediterranean-diet-guide/), where olive oil is the primary added fat. Higher intakes aren't necessarily better, as it contains a lot of calories. Two tablespoons provide about 240 calories, which needs to be considered in your overall energy intake (if that is a priority). The easiest, most effective benefit will come from replacing other fats (like butter, margarine, or refined oils) rather than simply adding olive oil on top of your current fat intake. ## How to add more olive oil to your daily diet _This post is for subscribers only._ ### Ultra-Processed Food Diet: A Review URL: https://www.alphabetguides.com/ultra-processed-food-diet/ Last updated: 2026-09-28T10:29:20.000Z summary - The ultra-processed food diet is dominated by industrially manufactured products containing ingredients not used in home cooking. - Its only practical advantages are convenience, long shelf life, and low cost per calorie — there are no health benefits. - People on UPF-dominated diets eat approximately 500 extra calories a day and have an increased risk of all the big diseases. Avoid. The ultra-processed food (‘UPF’) diet is not recommended one. It’s now a [modern eating habit](https://www.alphabetguides.com/western-diet/) that’s dominated by industrially manufactured food products. These products undergo extensive processing and contain ingredients rarely used in home cooking.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC10260459/?ref=alphabetguides.com) Unlike most traditional diets, which are designed to promote health, UPF diets represent an unintentional dietary shift resulting from the industrialisation of food, clever marketing, and convenience, all at low cost. UPF intake is growing and is currently over 50% of total calories in some Western countries.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/34684391/?ref=alphabetguides.com) UPFs are usually defined by the [‘NOVA’ system](https://www.alphabetguides.com/ultra-processed-food-an-introduction/). They are industrial products often containing five or more ingredients, and ones not used in home cooking (e.g., hydrogenated oils, high-fructose corn syrup, modified starches, protein isolates, emulsifiers, colourings, artificial flavours and preservatives). Common examples of UPFs include sugary beverages, packaged snacks, microwave snacks, mass-produced breads, breakfast cereals, reconstituted meat products (chicken nuggets, hot dogs), ready-to-eat meals, candy, cookies, ice cream, and most fast food items. UPFs all have the same traits. They’re [designed for convenience](https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/) (ready-to-eat and ready-to-heat). They’re “hyperpalatable”, high in fat, sugar, and salt. They’re heavily marketed, very profitable for manufacturers, and sometimes positioned as ‘healthy’ through misleading health claims. The extensive processing of UPFs disrupts their natural food structure, concentrating calories, removing fibre (and other nutrients), and creating products that you can eat a lot of without feeling full.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31105044/?ref=alphabetguides.com) In recent decades, there’s been a shift toward [UPF-dominated diets](https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/), which has (unsurprisingly) coincided with rising rates of obesity, type 2 diabetes, cardiovascular and other chronic diseases.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/38418082/?ref=alphabetguides.com) The food environment in many developed nations now defaults to UPFs. They're readily available in schools, workplaces, hospitals, vending machines, convenience stores, and restaurants. This makes avoiding them difficult without deliberate efforts. --- ## Example foods and dishes - **Breakfast:** - Frosted cereal with whole milk and a toaster pastry - Drive-through breakfast sandwich (sausage, egg, cheese) and energy drink - **Lunch:** - Instant ramen with canned hot dogs - Fast-food burger, large fries, and milkshake - **Snack:** - Chips and dip - Packaged cookies and energy drink - **Dinner:** - Frozen pizza with garlic breadsticks and soda - Fried chicken, mac and cheese, with a brownie - **Dessert:** - Packaged cupcakes - Ice cream - **Drinks:** Flavoured coffee drink, soda, energy drink --- ## Pros The only ‘benefit’ of UPFs is their convenience rather than health. They require little to no preparation time, cooking skills, or equipment, which makes them attractive for people with limited time, a lack of cooking facilities or knowledge, and families managing busy schedules. UPFs have extended shelf lives, which reduces food waste and the number of times you have to go shopping. Their widespread availability and relatively low cost (particularly per kcal) make them accessible to people on low incomes and those with limited access to healthy foods. ## Cons The limitations of UPF-dominated diets are [severe and well known](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/). The nutritional quality of UPFs is severely compromised as they contain high levels of added sugars, saturated fat, sodium, and calories. They’re usually missing protein (per kcal), dietary fibre, and most essential nutrients.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/34684391/?ref=alphabetguides.com) Research has consistently shown that increasing UPF intake is associated with increased risk of nutrient deficiencies. [Weight gain and obesity](https://www.alphabetguides.com/tag/fat-loss/) also represent major concerns. People who consume UPF-based diets eat approximately 500 calories a day more on average and go on to [gain weight](https://www.alphabetguides.com/upfs-and-fat/). Several large-scale studies across multiple countries show strong associations between UPF intake and body fat — the more you eat, the fatter you get.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31105044/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/32792031/?ref=alphabetguides.com) It’s no surprise that there is also a link between UPF intake and [cardiovascular disease](https://www.alphabetguides.com/tag/heart-health/). In addition to increased body fat, UPF intake is also associated with inflammation, a poor gut microbiome, higher exposure to food additives and contaminated packaging, and they also ‘crowd out’ healthier foods. So, in addition to the cardiovascular disease risk, they have also been linked to certain cancers, depression, metabolic health, [cognitive function and brain health](https://www.alphabetguides.com/tag/brain-health/).[\[6\]](https://pubmed.ncbi.nlm.nih.gov/31142457/?ref=alphabetguides.com) --- ## Bottom Line The UPF diet represents a cautionary tale of modern dietary patterns that are actively harming public health. Robust high-quality evidence consistently links UPFs to increased risks for obesity, cardiovascular disease and many other health issues. They have no benefits beyond their convenience. --- ## Overall Score: **★☆☆☆☆** - Health Benefits: **★☆☆☆☆** - Nutrition: **★☆☆☆☆** - Weight Control: **★☆☆☆☆** - Ease to Follow: **★★★★☆** - Safety Profile: **★☆☆☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

[Ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-diet/) (UPFs) are associated with higher risks of obesity and many serious long-term diseases. This article summarises current evidence on the potential health harms linked to UPFs. As UPF consumption increased globally, researchers began investigating potential health concerns associated with it. Over the past decade, the evidence has accumulated from around the world. The findings have been consistent enough to attract attention from several public health organisations and start debates about changing regulations and dietary guidelines. ## Why are ultra-processed foods under scrutiny? For decades, nutrition research focused primarily on nutrients: fat, protein, carbohydrates, vitamins, and minerals. It was assumed that the health effects of food depend solely on what it is made of. However, researchers observed that despite people consuming similar amounts of calories and nutrients, they had different health outcomes and [body weights](https://www.alphabetguides.com/upfs-and-fat/). They also noticed that people would naturally start to eat more of certain foods compared to others, even if they had the same amount of calories and nutrients. So rather than focusing on just the content of the food, scientists started looking at the structure and processing methods used in different food products. This opened UPFs to scrutiny, as researchers found that people who eat a lot of UPFs tend to have poorer health.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/38418082/?ref=alphabetguides.com) ### Ultra-processed foods and obesity The relationship between UPF intake and body weight has received a lot of attention. Many studies find consistent links between higher UPF intake and increased risk of overweight and obesity. This link is consistent across people of different ages and across different countries. The more UPFs that are consumed, the more fat you're likely to have. When people are offered UPFs, they tend to consume more of them, about 500 calories a day more, and then go on to gain weight.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/31105044/?ref=alphabetguides.com) ### Ultra-processed foods and heart disease Research consistently links higher UPF intake to increased risk of [cardiovascular disease](https://www.alphabetguides.com/tag/heart-health/), type 2 diabetes, high blood pressure, high cholesterol and high blood sugar levels. Even those with normal body weights are still at greater risk of cardiometabolic disease with higher UPF intakes. ### Ultra-processed foods and cancer risk Some studies report associations between UPF consumption and certain cancers, particularly breast, colorectal, pancreatic and gastrointestinal cancers (cancers related to the digestive tract). Just a 10% increase in the proportion of UPFs in your diet is linked to higher cancer risk — that’s equivalent to a small UPF snack a day.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/37087831/?ref=alphabetguides.com) ### Mental health A recent study has linked consistent associations between higher UPF intake and increased risk of [depression and anxiety](https://www.alphabetguides.com/tag/brain-health/). This is thought to be due to increased inflammation, changes to your gut microbiome, and [fluctuating blood sugar levels](https://www.alphabetguides.com/reduce-sugar-intake/).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/38418082/?ref=alphabetguides.com) --- ## How do ultra-processed foods affect your health? ### Energy density and calorie intake UPFs typically pack many calories into small volumes of food — they are “energy dense”. This high energy density makes consuming more calories easier. In other words, you can eat a lot more calories before feeling full.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/31142457/?ref=alphabetguides.com) Even when two foods have the same nutritional content: the same calories, fat, carbohydrate, salt, and sugar, people tend to eat more of the UPF than minimally processed alternatives. ### Eating rate and food structure UPFs often have soft textures, which means they don't need to be chewed as much. This allows faster eating, which is associated with consuming more calories. The food structure matters as well as the nutrient content.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/39771019/?ref=alphabetguides.com) Chewing whole foods slows eating and may trigger feelings of fullness more effectively. Processing breaks down food structure, making calories and nutrients more readily available, but potentially speeding up your natural eating pace. ### “Hyperpalatability” and reward UPFs are designed to be highly palatable through specific combinations of fat, sugar, salt, and other strong flavourings. While there’s nothing wrong with foods tasting good, certain combinations may affect brain reward pathways in ways that encourage you to eat more of them.[\[6\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4818794/?ref=alphabetguides.com) The brain's reward system is hardwired to encourage us to eat energy-dense foods, which were scarce throughout most of human history. However, eating UPFs seems to stimulate these pathways more intensely than minimally processed alternatives. ### Satiety and hunger signals Eating food affects our feeling of fullness in a few ways: stomach expansion, sensing nutrients in the gut, hormonal release, and blood sugar patterns. UPFs may interact differently with these systems compared to whole foods. Some UPFs are digested rapidly, causing quick rises and falls in blood sugar that can trigger renewed hunger and cravings. Other UPFs may not trigger satiety hormones as effectively as whole foods, even when providing the same amount of calories. ### Your microbiome The gut microbiome influences many other systems around the body: your metabolism, inflammation, and potentially even your mood and behaviour. Some studies suggest that emulsifiers and other additives common in UPFs may negatively affect your gut and the bacteria in it. ### Displacement of nutritious foods A simpler, but overlooked cause, also deserves a mention. If UPFs take up a large portion of your diet, they replace other (healthier) foods. Even if UPFs weren’t actively harmful, if they go on to replace [fruits, vegetables,](https://www.alphabetguides.com/tag/plant-based/) legumes, and other whole foods, this means you’ll miss the beneficial nutrients contained within them. --- ## Frequently Asked Questions #### ****What are examples of ultra-processed foods?** Ultra-processed foods are industrial products containing ingredients rarely found in home cooking. They contain ingredients like emulsifiers, artificial flavours, sweeteners, and preservatives. Common examples: packaged snacks (crisps, biscuits), soft drinks, fast food, mass-produced bread and cereals, ready meals, processed meat (sausages, nuggets), and most flavoured yoghurts. The "NOVA" classification is the standard for identifying them. #### ****How much ultra-processed food is safe to eat?** Research has not identified a completely safe threshold. Research shows that the more UPFs consumed, the greater the health risks, so even low consumption carries a lower risk. Most experts recommend keeping UPFs to a minimum; the lower the better. #### ****Do ultra-processed foods cause cancer?** Associations between high UPF intake and several cancers, particularly breast, colorectal, and pancreatic cancer. These are **speculated* to be caused by food additives, packaging contaminants, and the displacement of (healthier) protective whole foods in your diet. #### ****Why are ultra-processed foods bad for you?** The harms come from many places: UPFs displace nutritious whole foods; they are designed to be hyperpalatable, causing overconsumption (studies show people eat around 500 more calories daily when offered UPFs). They contain additives, which damage your gut microbiome and hormones, and cause inflammation. The degree of processing itself appears to cause harm beyond the nutrient profile. #### ****What is the NOVA food classification system?** NOVA classifies foods into four groups by processing level: - Group 1 ("unprocessed foods", e.g. vegetables, eggs, meat). - Group 2 ("culinary ingredients", e.g. oils, flour, salt). - Group 3 ("processed foods", e.g. cheese, canned legumes). - Group 4 ("ultra-processed" — industrial formulations with multiple additives). It is the most widely used framework in research on ultra-processed food. --- ## Bottom Line The evidence linking UPFs to poor health has accumulated over the past decade. However, there are still questions that remain unanswered. Which UPFs or processing methods are affecting health? Do UPFs interact with other dietary, lifestyle, or genetic factors? Is there a “safe” amount of UPFs you can eat? Can exercise offset UPF intake? Can a better diet counteract eating some UPFs? The research will continue. Guidelines and regulations may evolve, as they have already in many countries. But in the meantime, the evidence suggests that keeping UPF intake to a minimum, where practical, and in most cases, replacing them with whole foods, is advised. This doesn't necessarily mean eliminating all UPFs or feeling guilty about realistic food choices. It does suggest that reducing reliance on these products, when feasible, likely supports better health prospects. --- #### Sources 1. Lane MM et al.

Batch-cook at the weekend and the hard part is already done. Recommendations for vegetable portions focus on meeting nutritional needs and reducing disease risk. This article provides practical, evidence-based guidance on how much of your plate should be veggies. Most people probably know they should eat more vegetables. But how much is enough? So, here is a simple rule to follow: half your plate at lunch and dinner should be vegetables. Large-scale research on thousands of people has shown clear evidence that eating fruit and vegetables reduces cardiovascular disease, cancer and early death. The beneficial effects of eating vegetables increase with each additional serving, up to 800 grams per day — approximately 10 servings! That means doubling your 5 a day! Each extra serving of vegetables a day reduces disease risk by about 10%.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/28338764/?ref=alphabetguides.com) So, what's the problem? Most people eat fewer than two servings of vegetables a day. The ‘vegetable intake gap’ between what we actually eat and what we should eat helps explain the increase in some diseases. It wasn't always like this. People used to eat a lot more vegetables than they do now. Vegetables have been crowded out by cheaper, less healthy, [ultra-processed alternatives](https://www.alphabetguides.com/ultra-processed-food-an-introduction/). ## How many servings of vegetables per day? The half-plate rule Rather than trying to count servings with scales and measuring cups, use a visual guide: fill half your plate with non-starchy vegetables at your two main meals each day. This approach is supported by nutrition research, making it easier to hit recommended intake levels without having to spend time measuring or tracking them.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/35215542/?ref=alphabetguides.com) Fill the remaining plate space with a quarter of lean protein (fish, poultry, legumes, eggs) and the other quarter with wholegrain carbohydrates (brown rice, quinoa, wholegrain pasta, potatoes). This creates a balanced meal that's naturally lower in calories, keeping you fuller for longer. Why does this work? The answer is that vegetables have very [low energy density](https://www.alphabetguides.com/volumetrics-diet/) — meaning you can eat a large volume of them for relatively few calories. A full plate of roasted vegetables might contain 150 calories, whilst the same volume of pasta could contain 600 calories or more. The high fibre and water content of vegetables also slows digestion, stabilises blood sugar, and triggers satiety signals that help prevent overeating. ## How to eat more vegetables The beauty of the half-plate rule is its simplicity. You don't need special equipment or complicated calculations. Start your meal prep by thinking about which vegetables you'll serve, then build the rest of the meal around them. Cook vegetables in ways that make them genuinely appealing. Roasting can bring out their natural sweetness. Using extra virgin olive oil (before and/or after cooking them) enhances flavour and actually increases absorption of fat-soluble vitamins and some beneficial [plant nutrients](https://www.alphabetguides.com/plant-based-diet-meal-plan/). Season with garlic, herbs, and lemon juice if you aren’t fond of vegetables' natural flavours.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/31010212/?ref=alphabetguides.com) Batch cooking helps make this sustainable. Roast several trays of mixed vegetables on Sunday evening, and coat them in extra virgin olive oil. Then throughout the week, add them to grain bowls, toss them with pasta, layer them in sandwiches, or simply reheat them as an instant side dish. --- ## Roasted Mediterranean vegetable platter This is your foundation [recipe](https://www.alphabetguides.com/tag/recipes/) — endlessly adaptable and always tasty. It has several regional variations: it is called Ratatouille in France, Briam in Greece, Pisto in Spain and Caponata in Italy. There is a reason why every country in the [Mediterranean](https://www.alphabetguides.com/tag/mediterraneandiet/) has their own name for it. ![A platter of grilled Mediterranean vegetables.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1770119027724-cc85afb2cae5.jpeg) ### Ingredients - Courgettes, aubergines, bell peppers (any colour), red onions, tomatoes - 3-4 tbsp extra virgin olive oil - 3-4 garlic cloves (crushed) - 1 teaspoon dried oregano, fresh basil, salt and black pepper. ### Directions 1. Heat oven to 200°C (390°F). 2. Chop vegetables into similar-sized chunks or circles. 3. Toss with olive oil, garlic, oregano, salt, and pepper. 4. Spread on two large baking trays — don't overcrowd. Roast for 35–40 minutes until golden, stirring halfway through. 5. Tear over fresh basil before serving. Serves 4 as a main vegetable portion. --- ## Mixed green salad with lemon dressing A substantial salad that fills half your plate without sacrificing taste. Add chickpeas or white beans to make this a complete meal, or serve alongside grilled fish or chicken. ### Ingredients - Mixed salad leaves (rocket, spinach, watercress) - ½ cucumber (diced) - 10 cherry tomatoes (halved) - 1 ripe avocado (sliced) - A handful of fresh herbs (parsley, mint, dill) - 2 tbsp extra virgin olive oil - Juice of 1 lemon - 1 garlic clove (puréed) ### Directions 1. Combine all salad vegetables in a large bowl. 2. Whisk together olive oil, lemon juice, garlic, salt, and pepper. 3. Pour over salad just before serving and toss well. 4. Top with sliced avocado and torn herbs. --- ## Sautéed greens and mushrooms Ready in 10 minutes, serve with roast or seared meat. Goes especially well with lamb or beef. ### Ingredients - 300g (10 cups) mixed greens (kale, chard, or spinach — roughly chopped) - 250g (9oz) mushrooms (sliced) - 2 tbsp extra virgin olive oil - 3 garlic cloves (sliced) - 1 tsp chilli flakes (optional) - A squeeze of lemon ### Directions 1. Heat olive oil in a large frying pan. 2. Add mushrooms and cook for 5 minutes until golden. 3. Add garlic and chilli flakes, and cook for 1 minute. 4. Add greens in batches, stirring until wilted. 5. Season with salt, pepper, and lemon juice. 6. The kale and chard need 5–7 minutes of cooking, and the spinach wilts in 2–3 minutes. --- ## Action steps Start with three days this week. For lunch and dinner, fill half your plate with vegetables before adding anything else. Notice how you feel — most people report feeling fuller, more energised, and less prone to afternoon slumps. Keep pre-washed salad leaves, cherry tomatoes, and pre-cut vegetables in your fridge for quick assembly. Stock your freezer with frozen vegetables like broccoli, peas, and spinach — they are just as good as fresh vegetables. The half-plate rule isn't about restriction. It's about abundance — filling your plate with [colourful](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/), flavourful vegetables that nourish your body whilst leaving you feeling full for fewer calories. #### Sources 1.

The ‘high-protein’ diet says what it means: increasing your dietary protein intake. Technically, it's defined as protein intakes that obviously exceed the recommended protein intakes by a clear margin. Current recommendations are around 0.8 grams per kg body weight a day, or around 15% total calories. So, in practice, ‘high’ protein intakes are over 1.2 grams per kg a day or 25% total calories. High-protein diets have become popular for maintaining healthy body weights, athletic performance and recovery, and for [building muscle](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/). Protein has a higher ‘thermic effect’ than carbohydrate and fats, meaning your body has to use *more* energy just to digest protein; it has to work harder. Around 20-30% of the calories from protein (so around 1 calorie per gram of protein) is used to digest it. Compare this to 5-10% for carbohydrates and basically nothing for fat. In addition to this, calorie-for-calorie, protein makes you feel fuller than carbs and fat do. It is also essential for preserving (or possibly increasing) your muscle mass, which helps keep your [body fat under control](https://www.alphabetguides.com/3-underrated-ways-to-lose-fat/). There is no single type of high-protein diet; it is really an umbrella term for a few different diets. Animal protein sources include lean meats, poultry, fish, eggs, and dairy products, while [plant-based options](https://www.alphabetguides.com/tag/plant-based/) are legumes, tofu, tempeh, nuts, seeds, and protein-rich grains like quinoa. Some people also take protein supplements such as whey, casein, or [plant protein](https://www.alphabetguides.com/plant-based-diet-meal-plan/) powders. The diet usually requires reducing carbohydrate or fat intake to balance total calorie intake, while protein intake is increased. The content of the diet varies widely, from moderate increases in protein-rich whole foods (e.g., [paleo](https://www.alphabetguides.com/paleo-diet/) and zone diet) to more extreme approaches severely restricting other macronutrients (e.g., [keto](https://www.alphabetguides.com/keto-diet/) and [carnivore](https://www.alphabetguides.com/carnivore-diet/) diets). --- ## Example foods and dishes - **Breakfast:** Protein pancakes with Greek yoghurt *or* Egg white omelette with turkey sausage & cottage cheese - **Lunch:** Large grilled chicken breast, quinoa & steamed broccoli *or* Large tuna salad on mixed greens & hard-boiled eggs - **Snack:** Protein shake with added Greek yoghurt *or* Beef jerky with string cheese - **Dinner:** Grilled salmon with lentils & asparagus *or* Lean beef stir-fry with edamame & brown rice - **Dessert:** Frozen Greek protein yoghurt - **Drinks:** Protein shake, skim milk --- ## Pros High-protein diets show consistent benefits for weight loss and improved body composition. Research shows these diets effectively reduce body fat while helping preserve muscle mass while you’re restricting your calorie intake (known in the trade as ‘[body recomposition](https://www.alphabetguides.com/nutrition-and-body-recomposition/)’). Upping the protein intake of calorie-restricted diets may make them a bit easier to follow and keep your hunger in check.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/25926512/?ref=alphabetguides.com) Evidence also indicates improvements in certain metabolic health markers, particularly for people who have type 2 diabetes and obesity. Studies show reductions in LDL cholesterol, total cholesterol, triglycerides, and insulin resistance.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/22510792/?ref=alphabetguides.com) The diet's ability to [support muscle growth](https://www.alphabetguides.com/back-to-basics-a-checklist-for-muscle-growth/) also makes it attractive for athletes and people who are engaging in regular exercise. The collective benefits of the diet make it a popular choice for managing your body weight. ## Cons Higher protein intake increases the amount of work your kidneys have to do, which *may* affect people with poor kidney function or who're risk of kidney disease. However, for healthy adults with no kidney problems, higher protein intake is generally considered safe.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/12144197/?ref=alphabetguides.com) The impact of higher protein diets on heart health is *less* certain and largely depends on what foods you are getting your protein from and the other parts of your diet. Diets dominated by red meat and processed meats can raise [cardiovascular disease risk](https://www.alphabetguides.com/tag/heart-health/) due to high saturated fat and sodium intake. Whereas [plant-based proteins](https://www.alphabetguides.com/plant-based-protein/) are associated with better health outcomes.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/16002829/?ref=alphabetguides.com) Very high protein diets that rely on animal proteins can crowd out other nutrients (e.g., dietary fibre) and negatively impact your gut microbiome. Excessive protein may increase calcium loss, which can *potentially* go on to affect your bone health. Because there is no single standard ‘high-protein’ diet, the evidence support it positive effects is messy and inconsistent. There are also practical issues, such as cost, monotony, and cultural preferences, that can make it difficult to follow.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/12144197/?ref=alphabetguides.com) ## Bottom Line High-protein diets offer short-term benefits for weight loss and metabolic health. However, there are notable safety concerns regarding kidney and cardiovascular health for *some* people. This, combined with limited long-term data, warrants caution and any blanket recommendations for them. These types of diets may work for healthy, physically active people aiming for [weight loss while maintaining muscle mass](https://www.alphabetguides.com/body-recomposition-lose-fat-gain-muscle/).[\[5\]](https://pubmed.ncbi.nlm.nih.gov/18175733/?ref=alphabetguides.com) --- ## Overall Score: **★★★☆☆** - Health Benefits: **★★★☆☆** - Nutrition: **★★★☆☆** - Weight Control: **★★★★☆** - Ease to Follow: **★★★☆☆** - Safety Profile: **★★★☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

URL: https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/ Last updated: 2026-09-22T10:00:24.000Z summary - Ultra-processed foods dominate modern diets because they solve real problems: they're cheap, fast, shelf-stable, and available everywhere. - Children in some countries now get 60–70% of their calories from ultra-processed food, and consumption is rising globally. - Telling people to "make better choices" ignores the reasons driving ultra-processed food intake. The food environment is a problem as well. [Ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-diet/) (UPFs) are manufactured products that are convenient, highly palatable, and shelf-stable, which helps explain their widespread popularity. This article examines the economic, social, and technological factors that have driven their popularity. In just a few decades, UPFs have moved from speciality items to dietary staples. In many high-income countries, these products now provide *more than half* of people's daily calories. This shift represents one of the most significant changes to eating patterns in human history. Understanding why this happened requires looking beyond individual food choices. The rise of UPFs reflects changes in food production, economics, work patterns, and the environment. No single factor explains their dominance. Instead, multiple forces seem to have converged to make these products both easy to make and appealing. A perfect storm, or maybe just a product of their environment? ## A brief history of ultra-processed food For most of human history, food preparation happened at home or in small-scale commercial settings (like restaurants or pubs). Preservation methods like drying, salting, and fermenting were used to extend shelf life, but didn't fundamentally transform food. Humans have been processing like this for thousands of years. The Industrial Revolution changed this. Canning technology, developed 200 years ago, allowed foods to last months without refrigeration. Commercial food processing expanded with the invention of refrigeration, pasteurisation, and mechanised production methods about 100 years ago. However, the real acceleration towards UPFs came after World War II. Military rations had shown that food could have a long shelf-life, be portable, and be engineered for a specific purpose. These technologies were then transferred into civilian markets. Frozen dinners appeared 70 years ago. Instant foods became popular in the 1960s. By the 1980s and 1990s, food science had advanced to create products with precisely controlled taste, texture, and stability. Research shows that UPF consumption began rising sharply in high-income countries during the 1980s and has continued increasing in many regions since, and continues to rise to date.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/32761763/?ref=alphabetguides.com) Despite consumption rising pretty much everywhere, UPF intake patterns vary in different regions and among different people. These patterns can reveal a bit about the reasons why UPFs became so popular. ## Who eats ultra-processed food? ### Geography High-income countries generally eat more UPFs. In the United States and the United Kingdom, studies suggest that UPFs provide 50-60% of total daily calories. Canada, Australia, and several European nations also eat similar amounts. Middle-income countries are also experiencing rapid increases. Brazil, Mexico, and Chile have seen substantial rises in UPF consumption over recent decades. In many rural lower-income countries, traditional diets still predominate. But urban areas in these countries now show increasing UPF intake as well. ### Age The bad news is that children and adolescents are consuming higher proportions of UPFs than adults. Research from multiple countries shows that UPFs frequently constitute 60 to 70% of children's calorie intake. Young adults tend to eat more UPFs, possibly reflecting time constraints, lack of cooking skills, and food environments on college campuses or in their early career settings. ### Wealth Poorer people in high-income countries tend to consume more UPFs, probably due to them being cheap and easy to buy. However, in middle- and lower-income countries, higher-income groups sometimes eat more UPFs, as these products can be status symbols (thanks to the marketing!). Education level, food literacy, and access to cooking facilities also influence consumption patterns. You can guess in what way. This also makes it difficult to target these people who are now driving increases in UPF intake globally. ## Why do people eat ultra-processed food? UPFs didn't become widespread by accident. They do offer genuine advantages that are there to complement [modern lifestyles](https://www.alphabetguides.com/western-diet/). ### Convenience Perhaps no factor matters more than convenience. UPFs require minimal preparation. Many need only opening or briefly heating. This matters enormously for people juggling work, family care, and other responsibilities. Cooking from basic ingredients takes time, skill, and energy. After a long workday, preparing a meal from scratch can feel daunting or exhausting. Opening a package feels manageable. This isn't laziness. It's a rational response for people who have limited free time. ### Cost UPFs tend to cost less per calorie than fresh foods like [fruits, vegetables](https://www.alphabetguides.com/tag/plant-based/), and minimally processed lean proteins. A frozen pizza might feed a family for less money than a freshly made one from scratch (especially when you add in the time cost). However, some UPF products are also more expensive. The cost advantage often depends on what else is available in the local area (e.g., specific products, local markets or Whole Foods). ### Shelf Life UPFs last weeks or months without refrigeration. For households without reliable transport to shops, adequate storage space in their home, or predictable schedules, shelf-life matters. It reduces food waste and the frequency of shopping trips. This advantage particularly benefits people in 'food deserts': people with limited mobility and families managing unpredictable schedules. ### Palatability and consistency Food manufacturers invest heavily in creating products that are tasty and can be produced consistently. Every bag of chips or chocolate looks and tastes the same. This predictability has value. The engineered palatability of UPFs isn't necessarily problematic in itself. But to achieve products that always look and taste the same at scale, they require industrial machine-based processing. This also seems to naturally encourage (along with other further processing steps) overconsumption, so they can be consumed more quickly and easily. ### Availability In many areas, UPFs are simply more available than healthier alternatives. Convenience stores, vending machines, gas stations, work cafeterias and coffee shops tend to stock UPFs almost exclusively, with limited fresh options. This isn't accidental. Distribution networks favour shelf-stable products with higher profit margins. Perishable foods require more complicated and costly logistics, preparation, storage, and management of food displays. ### “Modern lifestyles” The rise of UPFs occurred alongside changes in how people live and work. These changes created conditions where UPFs became not just convenient but necessary. Average work hours have increased in many countries over recent decades. More households have all adults employed outside the home. Commute times have lengthened. These changes have made less time available for food preparation. Shift work and irregular schedules further complicate meal planning. When work hours vary, maintaining regular cooking routines becomes difficult. In addition to extra work hours, people also report having more obligations: childcare, elder care, education, and household maintenance all compete for limited time. As a result, less time is given to cooking. Studies examining time allocations and dietary patterns find consistent associations between lack of free time and increased UPF consumption.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/30820487/?ref=alphabetguides.com) The way we obtain food has also changed. Traditional markets where people bought fresh ingredients every day have declined in many areas. Supermarkets located in suburban areas require a car. Urban corner shops (within walking distance of residential houses) increasingly stock packaged foods rather than whole foods. The number of fast food outlets and convenience stores has also grown in recent decades. These businesses create environments where UPFs are the default, the most visible, and the easiest option to eat, crowding out healthier foods. ### Marketing and availability Food companies spend billions on marketing UPFs. Children are bombarded with food adverts, which are predominantly for UPFs. These messages shape preferences and normalise eating UPFs. Product placement, promotions, and dominant shelf spacing in stores all direct people toward buying UPFs. This has been shown to influence decision-making, particularly when your ‘cognitive resources’ are depleted by [stress or tiredness](https://www.alphabetguides.com/what-is-cortisol/). ### Social and cultural dimensions Food choices don't tend to happen in isolation. Social norms, cultural traditions, and community practices all shape eating habits. Social eating occasions now nearly always feature UPFs. Birthday parties, workplace gatherings, and casual social meetings often centre around packaged snacks, soft drinks, and other UPFs. Opting out can feel socially awkward. Lack of time or change in culture has meant that fewer people are learning to cook. For people who can’t prepare meals from basic whole ingredients, UPFs fill this gap. ### Things beyond individual control _This post is for subscribers only._ ### Why the Scale Lies About Fat Loss — And Better Ways to Track Progress URL: https://www.alphabetguides.com/beyond-the-scale/ Last updated: 2026-10-11T12:47:46.000Z summary - BMI and scale weight can't distinguish fat from lean mass. For anyone exercising, they're often misleading and sometimes flat-out wrong. - Waist circumference is a simple, practical alternative that better reflects health risk and isn't skewed by the amount of muscle that you have. - Progress photos, clothes fit, strength improvements, and blood markers tell a more complete story. Use multiple measures, not just one number. There are more important things that can be measured beyond the number on a scale, including body composition, strength gains, and changes in how your clothing fits. This article explains practical, evidence-based methods to track progress better. You may have heard that weightlifting and building muscle are good for your health and for [losing fat](https://www.alphabetguides.com/3-underrated-ways-to-lose-fat/) — that’s undeniably true. ## Why the scales and BMI are unreliable measures of health So, you’ve been going to the gym consistently for months. Your clothes fit better, you notice it in the mirror, you feel stronger, and your friends are even making comments about it. But when you step on the scale, the number has barely moved — or worse, it's gone up. Frustrated, you wonder if all your hard work has been for nothing: “I’ve not even lost any weight”, you say to yourself. Here's the real truth: the scale is lying to you. Therefore, so is your Body Mass Index (BMI) if your doctor bothers to look at that sort of thing. These popular metrics, while simple to calculate and widely used, are fundamentally flawed when it comes to what health and fitness progress actually look like. We’ll explain how and why these measurements fail, and what you should think about looking at instead. ## Why is BMI a poor measure of fat loss? ### A 200-year-old tool that never fit BMI was developed in the 1830s by the Belgian statistician Adolphe Quetelet. It wasn't created to measure how fat or how fit a person was; it was created to study “population” trends across thousands of different people all at the same time. The formula is deceptively simple: take your body weight in kilograms and divide it by the square of your height in meters. A BMI over 30 classifies you as obese, while a BMI over 25 means you're overweight. While BMI correlates reasonably well with disease risks across “populations” (i.e., thousands of people all analysed together), it has flaws when it is used at an individual level. ### The fundamental issue? BMI cannot distinguish between fat mass and 'fat-free mass',which also includes muscle, bone, organs, and water. It treats all weight equally, when clearly (from a health perspective) it's not. Gaining one kilogram of muscle does not lead to the same health outcomes as gaining one kilogram of fat. In fact, in most cases, they have opposite effects on your health. Gaining muscle is nearly always good for your health. Whereas most of the time, gaining fat is bad. Consider this: if you gain 5 kilograms of healthy muscle through [strength training](https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/), this is something nearly every scientist and medical expert would agree is beneficial for your health.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/33173624/?ref=alphabetguides.com) However, despite the applause, your BMI will actually increase, suggesting you've become less healthy! The one exception is that if you're underweight to start with, which won't apply to most people, so this article is just for those who are looking at maintaining or losing weight, rather than gaining it. ### The exercise paradox This limitation is problematic for people who are exercising regularly, especially weightlifting, as it’s particularly efficient at stimulating muscle growth. Over the course of a resistance training programme, you can typically expect increases in your muscle mass to occur alongside decreases in fat mass — a highly desirable outcome. Yet because changes in muscle mass and BMI are positively correlated with each other, BMI is completely inappropriate for assessing progress in people who are exercising. If you’re thinking this doesn’t make sense, you’re right. Yes, the medical community will advise you to [exercise for weight loss](https://www.alphabetguides.com/exercise-fat-loss/), then, at the same time, use a flawed measure to assess your progress. Bizarre! Let me illustrate with a real-world example. Imagine an obese person weighing 100 kg (220 pounds) who is 1.8 meters (5 feet 11 inches). Their body fat is 40% (40 kg of fat and 60 kg of fat-free mass), and they have a BMI of 31 31 kg/m². Over several months of [exercise training](https://www.alphabetguides.com/tag/exercise/), they go on to lose 5 kg (11 lbs) of fat while simultaneously gaining 5 kg (11 lbs) of muscle — an excellent outcome. What happens to their BMI? Absolutely nothing. It remains at 31\. They’re still classified as “obese” even though their body fat percentage has dropped from 40 to 35%, and their health will have improved dramatically. Now, worse: imagine that they only lost 5 kg of fat; they would have reduced their BMI from 31 to 29\. They would no longer be defined as obese (just overweight), despite not losing a single gram of fat, and their body fat would have only dropped from 40 to 37%. It can technically get even worse. Imagine that person skips the gym, lies on their sofa and bed, and loses 5 kg of muscle. They’ll have been moved out of the obese category by their doctor, but their body fat would have **gone up** from 40 to 42%. These contradictions reveal why BMI fails as a measure for monitoring progress for people who are exercising. Any reduction in fat or body fat percentage can be completely offset by simultaneous increases in muscle mass. This makes BMI changes misleading or even discouraging for people doing exactly what they should be doing (from a health perspective). ### Beyond fat and muscle: water and carbohydrate The problems with scale weight extend even further. Your body weight fluctuates significantly based on factors that have nothing to do with gaining or losing fat. Even if you’re drinking the same amount of water every day, the amount of water in your body can vary by several pounds day-to-day based on your sodium intake, hormones, inflammation, menstrual cycle, stress, and medication. After eating carbohydrate-rich meals, your body stores carbohydrates for energy (as “glycogen”) in your muscles and the liver. Each gram of glycogen stored in your muscle takes 3–4 grams of water with it. This is why low-carb diets produce rapid initial “weight loss” after a few days — it's primarily water and glycogen, not fat.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/1615908/?ref=alphabetguides.com) Starting a new exercise program often causes temporary “water retention” in your muscles to repair and adapt. This means you could be burning fat while the scale stays the same or your weight even increases due to water weight — another way the scale misleads you about your actual progress.

BMI also fails to account for where fat is stored, which profoundly affects health risk. Two different people with identical BMIs can have vastly different amounts of fat and health profiles. One person might carry most of their fat subcutaneously (under the skin), while another may have a lot of dangerous [visceral fat](https://www.alphabetguides.com/visceral-fat/) around internal organs. Visceral fat is metabolically active and strongly associated with cardiovascular disease, type 2 diabetes, and other health complications. Subcutaneous fat, while not ideal in excess, is relatively benign. BMI treats these two types of fat equally, missing a crucial distinction for health. The concept of "metabolically healthy obesity” or “fat but fit” illustrates this further. While uncommon, some people are classified as obese by BMI but have normal health markers — maybe because they exercise regularly and have a lot of muscle despite also carrying extra fat. Given these substantial limitations, what should you track to assess genuine health and fitness progress? The correct answer depends on your goals, resources, and preferences, but there are several alternatives to consider that are more informative than BMI or scale weight alone. We’ll start with the simplest, most accessible methods you can use at home first. ## Waist circumference: simple and effective Waist circumference offers a practical alternative that better predicts [health risk](https://www.alphabetguides.com/candy-apple-phenotype/) than BMI. A waist measurement over 40 inches (102 cm) for men or 35 inches (88 cm) for women — or more than half your height, regardless of sex — indicates abdominal obesity and increased risk of disease.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/7613427/?ref=alphabetguides.com) Why this works better: Waist circumference correlates strongly with abdominal fat and visceral fat. It also remains relatively unaffected if you gain muscle from exercise (unlike BMI). For people participating in exercise programs, muscle gains primarily occur in the upper body and limbs. So, hip and waist measurements, away from these sites, can provide a viable, accurate alternative to BMI. ### How to measure waist circumference correctly: ![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/09/waist-circumference.jpg) - Use a flexible measuring tape, not one you use for measuring the skirting board. - Measure first thing in the morning before eating - Find the narrowest part of your torso (usually just above the belly button) - Keep the tape parallel to the floor - Breathe normally and measure after a natural exhale - Don't suck in or compress your abdomen - Measure at the same location every time Track this measurement weekly. A cheap measuring tape may be the most valuable progress-tracking tool you can buy. Although it’ll be less accurate, the fit of your trousers or belt will tell you the same story. ## Progress photos and measurements Never underestimate the power of visual documentation. There’s a reason why marketers use the before-and-after photos to sell their products. Progress photos, taken under consistent conditions, can provide good visual evidence of body composition changes that scales and BMI may miss. ### How to take effective progress photos: - Wear the same minimal clothing each time (swimsuit or underwear) - Use the same lighting and location - Take front, side, and back views - Shoot at the same time of day (morning is ideal) - Use the same camera distance and angle - Don't judge day-to-day — compare photos months apart To confirm what you think you’re seeing in the photos, combine them with body measurements (other than your waist) using your measuring tape. Measure your chest, upper arms, thighs, hips, or calves. These measurements can hint at where you're losing fat or building muscle, providing a more complete picture than a single number can. ## The bigger picture: other measures Health isn't just about how you look or what you weigh — it's about what your body can do. Tracking some simple “performance” metrics can provide some good supporting information and additional motivation for you. Examples include: - **Strength gains:** How much weight can you lift? Are you progressing on key exercises? - **Endurance:** How far or long can you run, walk, cycle, or swim? - **Function:** Can you play with your kids longer? Carry more groceries? Get off the floor more easily? - **Energy levels:** How do you feel throughout the day? - **Sleep quality:** Are you [sleeping better](https://www.alphabetguides.com/tag/sleep/)? Are you sleeping longer? - **Resting heart rate:** Lower is generally better. Take a 15-second measure. These functional improvements often come before the more visible physical changes and can tell you that your exercise program is working, even when the scale doesn’t budge. ## Metabolic health markers: what's happening inside Here's a crucial realisation: fat loss isn't always medically essential if your metabolic health markers are good. Direct health measures provide the most important information of all — what's actually happening in your body. Blood pressure, blood sugar, blood lipids, and inflammation can all be used to determine if you may need to lose fat, and can be used to track progress. Losing muscle, glycogen, and water may shift the scale weight, but it is unlikely to improve any of these health markers. It is also possible to have a high BMI or body weight and be perfectly healthy (termed “metabolically benign obesity”) — more reasons why the scale doesn't tell the complete story. ## Body fat: the technical gold standard Here's something that should be obvious but often isn't: obesity is defined by having “excessive body fat”, yet we typically don't measure body fat to diagnose or track it! This is like diagnosing anaemia without checking blood iron levels. Body fat percentage is the most common way of expressing the amount of body fat you have. It really tells you what “proportion” of your total weight comes from fat versus fat-free “lean tissue” (like muscle, bone, organs, water). This is the metric that truly reflects whether you're improving body composition, regardless of what happens to total body weight. It accounts for changes in muscle and fat. Healthy values range from 10-20% for men and 20-30% for women.[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC8399582/?ref=alphabetguides.com) --- ## How to measure body fat ### Bioelectrical impedance analysis (BIA): Found in smart scales and handheld devices, BIA sends a weak electrical current through your body. Fat and muscle conduct electricity differently, allowing the device to estimate your body composition. - **Pros:** It'sInexpensive, convenient, and can track trends at home. - **Cons:** Accuracy varies significantly based on your hydration status, recent meals, exercise, and device quality. Absolute numbers may be off by several percentage points. - **Best use:** Tracking changes in the numbers rather than what the numbers actually are. Measure under consistent conditions (same time of day, hydration level). ### Skinfold callipers: This is where a trained practitioner pinches your skin at specific sites and measures the thickness with callipers, then uses some equations to estimate your body fat. - **Pros:** Relatively inexpensive, portable. - **Cons:** Accuracy depends heavily on the skill of the person who’s doing it. It is difficult to do it on your own consistently, and less accurate for very thin or very fat people. - **Best use:** When performed by an experienced practitioner for periodic assessments ### DEXA scan (dual-energy X-ray absorptiometry): This is the clinical gold standard. It was originally developed to measure bone density. DEXA scans use low-dose X-rays to precisely measure bone mass, fat mass, and lean mass throughout your entire body. - **Pros:** Highly accurate, shows exactly where fat is located (or has been lost/gained), measures visceral fat, reveals muscle distribution, provides bone density data - **Cons:** More expensive ($50-150 per scan), requires travelling to a facility, and involves some radiation exposure. - **Best use:** Baseline assessment and periodic check-ins (every 3–12 months) to track comprehensive body composition changes. ### Hydrostatic (underwater) weighing: Considered very accurate, this method weighs you underwater to determine body density and calculate your body fat. - **Pros:** Highly accurate when done properly. - **Cons:** Uncomfortable for many people, requires specialised equipment and facilities, and is inconvenient. - **Best use:** Research settings or baseline assessments if DEXA is unavailable ## Putting It Together _This post is for subscribers only._ ### Atkins Diet: A Review URL: https://www.alphabetguides.com/atkins-diet/ Last updated: 2026-09-15T02:55:57.000Z summary - The Atkins diet is a low-carb, high-protein diet, designed to shift the body from burning carbohydrates to fat. - It produces marginally better short-term weight loss compared to standard weight loss diets, but long-term outcomes are roughly the same. - There are nutritional and cardiovascular concerns for some people, and better options exist for general health and controlling your weight. The Atkins diet is a low-carb, high-fat, high-protein diet created by cardiologist Dr Robert Atkins in the 1970s. The diet works by restricting carbohydrate intake. This shifts the body from using carbohydrates for fuel to fat, which targets fat loss while allowing unrestricted intake of protein and fat. The diet is structured in phases, beginning with a highly restrictive “induction” phase that limits carbohydrate intake to about 20 grams per day (primarily from non-starchy vegetables). After this, carbohydrates are gradually reintroduced while monitoring responses to them. The foods emphasised in the diet are: meat, fish, eggs, cheese, oils, butter, and low-carbohydrate vegetables. Whereas grains, [legumes](https://www.alphabetguides.com/plant-based-protein/), most fruits, starchy vegetables (e.g., potatoes, peas and corn), and sugar are severely restricted or eliminated. That said, there are modified versions of the diet that are less restrictive. The reduced carbohydrate intake lowers the amount of a hormone called insulin that is released. This increases the release and burning of body fat. So, proponents of the diet argue it offers advantages for weight loss and fat loss beyond simple calorie restriction. However, it also requires a significant departure from recommended dietary guidelines (based on whole grains, [fruit and vegetables](https://www.alphabetguides.com/tag/plant-based/)).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/15351198/?ref=alphabetguides.com) --- ## Example Foods & Dishes - **Breakfast:** - Fried eggs with bacon, cheddar cheese, and spinach. - Low-carb protein shake made with cream & berries. - **Lunch**: - Bunless bacon cheeseburger, salad and dressing. - Grilled chicken Caesar salad, no croutons. - **Snack:** - String cheese and pepperoni slices. - Celery sticks with cream cheese. - **Dinner:** - Ribeye steak with butter, roasted broccoli and cheese sauce. - Baked salmon with asparagus and hollandaise sauce. - **Dessert:** Sugar-free gelatin with whipped cream. - **Drinks:** Black coffee and cream, unsweetened iced tea --- ## Pros The health benefits of the Atkins diet are limited to certain conditions, rather than promoting good all-round health. Some versions of the diet have been shown to help reduce seizures and improve quality of life in epilepsy patients. There’s also some evidence suggesting that it may improve [brain health](https://www.alphabetguides.com/tag/brain-health/) in Alzheimer’s disease and improve the quality of life in cancer patients.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/24386671/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/27525031/?ref=alphabetguides.com) Several studies have shown that the Atkins diet outperforms low-fat diets for weight loss over 6 months, but is about the same over 12 months, so marginally better for short-term weight loss. The weight loss you see on the diet tends to come from reduced calorie restriction, as a result of the higher protein and fat intake, rather than any underlying metabolic changes.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/15351198/?ref=alphabetguides.com) ## Cons The diet is nutritionally restrictive and creates a risk of deficiencies (e.g., vitamins, minerals, dietary fibre). Researchers have reported that the diet *increases* the risk of cardiovascular disease in *some* people. Gut health issues (constipation and irregular bowel movements) are also reported. There are also links between the Atkins diet and damage to the organs and [blood vessels](https://www.alphabetguides.com/tag/heart-health/).[\[4\]](https://pubmed.ncbi.nlm.nih.gov/16037240/?ref=alphabetguides.com) Adherence to the diet is low. Its restrictive approach, limited food choices, the cost and social and cultural barriers make it difficult to follow. The health benefits beyond some specific ‘neurological’ conditions are limited, and uncertainty around the long-term cardiovascular disease risks is problematic.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/15351198/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/24386671/?ref=alphabetguides.com) --- ## Bottom Line Under medical supervision, the Atkins diet can be used to clear up some specific ‘neurological’ conditions, and the weight loss is comparable to other calorie-restriction diets. However, there are concerns about nutritional adequacy, long-term impact on health and how practical the diet is to follow. For general health and maintaining a [healthy body weight](https://www.alphabetguides.com/tag/fat-loss/), we believe there are better diets around. --- ## Overall Score: **★★★☆☆** - Health Benefits: **★★★☆☆** - Nutrition: **★★☆☆☆** - Weight Control: **★★★☆☆** - Ease to Follow: **★★☆☆☆** - Safety Profile: **★★★☆☆** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

(And How to Spot Them) URL: https://www.alphabetguides.com/ultra-processed-food-an-introduction/ Last updated: 2026-09-21T13:06:11.000Z summary - Ultra-processed foods are industrially manufactured products made from substances rarely found in your kitchen. - They're engineered for convenience, palatability, and shelf life, not nutrition. And classified based on the degree of processing. - The odd UPF won't harm you. Problems arise when they dominate the diet, which, in many Western countries, they already do. [Ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-diet/) are industrially manufactured products made from ingredients that have been significantly altered from their original form. You won't find them, in any form, growing in the wild. They are made by man, not by nature. This article introduces what ultra-processed foods actually are. Supermarkets are filled with foods ranging from those that have been minimally changed from when they were harvested in the field to highly processed products that are no longer recognisable. These differences matter because emerging research suggests that how (and what) food is processed may affect your health. This occurs over and above the nutritional content of the food alone. Ultra-processed food (UPF for short) has become a focus of health and nutrition science over the past decade. But before we look further any further into them, it is useful to define what a UPF actually is and how you can identify them. ## What are ultra-processed foods? In 2009, researchers at the University of São Paulo introduced a 'framework' to categorise foods based on the processing they’ve been through and what they’re used for. This system divides foods into four groups.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/30744710/?ref=alphabetguides.com) ### Group #1: unprocessed and minimally processed foods These are foods in their natural state or altered only slightly. Examples include fresh [vegetables and fruits,](https://www.alphabetguides.com/tag/plant-based/) eggs, milk, plain yoghurt, dried beans, and frozen vegetables. The processing these foods go through is minimal, usually just washing, removing inedible parts, drying, freezing, or pasteurising for safety. ### Group #2: processed culinary ingredients This group includes 'extracts' from Group 1 foods that are used in cooking. Think [olive oil](https://www.alphabetguides.com/superfood-olive-oil/) (from olives), butter (from milk), sugar (from plants), salt (from the sea), and honey (from honeycombs). You wouldn't (or shouldn’t) eat these alone for a meal, but they are there to help prepare other foods (ideally from Group 1). ### Group #3: processed foods These foods result from adding Group 2 ingredients to Group 1 foods. The goal of this type of processing is (primarily) to preserve the food product or improve its flavour. Canned vegetables with salt, tinned fish in oil or brine, freshly made bread (just flour, water, salt, yeast), and simple cheeses fall into category 3\. These foods aren’t inherently bad (in limited amounts), as they still retain a lot of their original nutritional value. ### Group #4: ultra-processed foods This category includes products that are made mostly or entirely from substances derived from food (Group 2) and artificial substances (like preservatives and other additives). Little of the Group 1 food is still intact. To make these foods, companies use industrial processes like hydrogenation, extrusion, moulding, and pre-processing for fractionation. Not processes you can easily do at home. The result is products designed for convenience, palatability, and shelf life — not nutrition ([or health](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/)). --- ## Definition of 'ultra-processed'? There’s no single quick rule that you can use to define UPF. But there are several things to look out for that they all have in common. ### #1\. Industrial formulations UPFs are typically created in factories rather than kitchens. They contain ingredients rarely used in home cooking, like protein isolates, modified starches, hydrogenated oils, and artificial additives. These things are added for flavour, texture, or shelf-life, not for nutrition. ### #2\. Multiple processing steps The creation of UPFs involves several industrial processing techniques. A group 3 food may go through one or three processes, whereas UPFs go through dozens. Studies show that these processes alter the food in ways that negatively affect digestion and metabolism for your health. ### #3\. Ready to consume Most UPFs require little or no preparation. They're designed for immediate consumption or simple heating (usually in the microwave). This convenience means you're more [likely to eat them](https://www.alphabetguides.com/why-ultra-processed-foods-become-popular/), eat more of them, and eat them more often. ### #4\. Palatability engineering Manufacturers formulate UPFs to maximise taste by combining fat, sugar, salt, and other flavourings. While these ingredients aren’t inherently toxic, they tend to be overconsumed (compared to minimally processed alternatives), which negatively affects your health. ### #5\. Number of ingredients While not a perfect rule, UPFs typically have long ingredient lists containing things you wouldn't find in a home kitchen. Look for unfamiliar ingredients like maltodextrin, modified corn starch, protein isolates, or various numbered additives. Having a long ingredient list doesn’t define a UPF by itself, as some healthy food products might have many ingredients as well. ### #6\. Packaging and marketing UPFs typically come in manufactured packaging with health claims and appealing graphics. They're typically colourful and positioned as a convenient meal replacement or snack. The package might emphasise fortification with vitamins or minerals, attempting to convey nutritional value. Typical examples of UPFs include: soft drinks, packaged snacks, mass-produced bread, sugary breakfast cereals, instant snacks, energy bars, chicken nuggets, hot dogs, and microwave meals. Notably, price doesn't determine the level of processing it's been through. Both budget and premium products can be 'ultra-processed'. ## Grey areas Not everything fits neatly into these four categories. Some products fall outside and occupy a middle ground. For example, plant milks, protein powders, protein bars, flavoured yoghurts, and “whole-grain” products are all difficult to allocate to specific categories. Some UPF products can be made with natural ingredients, sweeteners, and minimal processing (or even at home). However, other products in the same category contain artificial additives, preservatives, flavourings and have been through multiple rounds of processing. Not all UPF products are created equal. These grey areas highlight a limitation. So the classification system is a tool, not a rule. Don’t expect them to accurately capture and classify every product you buy at the supermarket. ## Why do we need definitions anyway? The short answer is the consumer probably doesn’t. No one is going to go around the supermarket with a 26-point checklist, trying to see which group every item on your list is before putting it into your basket. However, researchers require strict definitions so they can analyse them. How many UPFs do people eat? How many UPFs do different groups of people eat? How do they affect health? What type of UPFs do people eat? Why do people eat UPFs? What would happen if we taxed UPFs or limited their availability? How can consumers identify or be aware of UPFs? All these questions require strict criteria to define them. But as individual people, most of us don’t have to worry about rigid rules and technical definitions. Eating the occasional UPFs isn’t going to negatively affect your health by itself; problems start to arise when UPFs dominate your diet, eaten every day and in place of healthy foods. Context also matters. Someone with limited time, resources, or access to fresh food might rely more on UPF options. That's a practical reality, not a moral failing. The goal of the classification of UPFs at this stage isn't about judgment but understanding what they are. ## Looking ahead UPFs are now embedded in many food systems around the world. Defining them is just the first step. The next thing we need to know is how these products become so popular. What factors drove their expansion from niche convenience items to dietary staples?

Oily fish remain the most practical source. - Aim for at least one serving per week. Canned options make this affordable and easy. Supplements are a second option. Oily fish are fish with higher fat content that provide long-chain omega-3 fatty acids, which support cardiovascular, brain, and metabolic health. This article explores the key health benefits of consuming these nutrient-dense fish regularly. They include fish like salmon, trout, mackerel, sardines, herring, and anchovies, which are defined by their higher fat content compared to white fish. Specifically, it’s all about the long-chain omega-3 fatty acids. These fats are largely absent from typical Western diets and difficult to obtain in meaningful amounts from other foods. Unlike white fish (like cod, flatfish, or tilapia), which primarily store fat in their liver, oily fish distribute fat throughout their flesh. This is why they provide a reliable and concentrated source of omega-3s in a normal portion size. ## Is fish high in omega-3? Oily fish stand out, nutritionally, because they supply two omega-3 fatty acids: eicosapentaenoic acid ('EPA') and docosahexaenoic acid ('DHA'), which are difficult to find anywhere else in nature. While small amounts of omega-3s are found in some plant foods, these do not provide the same compounds, quantities or benefits. Because EPA and DHA are not efficiently produced by the body and are not found in many other foods, oily fish represent one of the most efficient ways to increase intake through diet alone. Some plant foods, such as flaxseed, walnuts, and chia seeds, contain another omega-3 called alpha-linolenic acid ('ALA'). While ALA is beneficial by itself, the body converts ALA into EPA and DHA very inefficiently. As a result, relying on plant sources alone typically leads to low levels of EPA and DHA. For most people, oily fish remain the most practical dietary source of these fats. ## Health effects EPA and DHA are incorporated into the 'cell membranes' throughout your body, where they help control inflammation, brain health and[ cardiovascular health](https://www.alphabetguides.com/tag/heart-health/)1. This is why you need them.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC3257651/?ref=alphabetguides.com) Regular consumption of oily fish is associated with a lower risk of cardiovascular disease and major cardiovascular events such as heart attack and stroke, even at relatively modest intakes. These benefits appear strongest in people who don't get a lot of omega-3 from their diet.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/31567003/?ref=alphabetguides.com) DHA is also a major structural component of your brain. It makes up a large proportion of the polyunsaturated fats found in brain tissue and plays a role in maintaining normal brain structure, brain function and [brain health](https://www.alphabetguides.com/tag/brain-health/). Thus, higher intakes of oily fish have been associated with better cognitive performance in older adults and a lower risk of cognitive decline, dementia, and Alzheimer’s disease. Researchers believe these effects are partly due to substances derived from EPA and DHA that help protect brain cells from damage and support brain cell maintenance as you age.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/39162889/?ref=alphabetguides.com) ### Additional benefits In addition to omega-3s, oily fish also provide a range of other nutrients and health benefits. A typical 100g (3.5 oz) serving of oily fish can provide: 50-100% of your vitamin D, 20–25 grams (1 oz) of [high-quality protein](https://www.alphabetguides.com/tag/protein/), vitamin B12, niacin and selenium. Smaller species, such as sardines and anchovies, are often eaten with their soft, edible bones, which can also provide calcium. You won't get that from the supplements. ### How much do you need? Recommendations vary slightly, but most experts suggest eating fish at least twice per week, with at least one serving being oily fish. In practical terms, this equates to 200–250 grams (7–9 ounces) of fish per week. Most oily fish provide 1.3–2.5 grams of EPA and DHA per 100 grams, meaning that even one or two servings per week can substantially increase your omega-3 intake. --- ## How to increase your intake of fish _This post is for subscribers only._ ### Blue Zone Diet: A Review URL: https://www.alphabetguides.com/blue-zone/ Last updated: 2026-09-04T14:48:53.000Z summary - The Blue Zone diet is a flexible, plant-based eating pattern based on the shared dietary habits of the world's healthiest places. - It's nutritionally complete, safe and associated with better health and healthier body weights. - However, its health benefits are largely observational and anecdotal, and have not been replicated outside the "blue zones". The “Blue Zone Diet” is the traditional dietary pattern taken from five “Blue Zone” regions around the world: Sardinia (Italy), Okinawa (Japan), Loma Linda (California), Nicoya Peninsula (Costa Rica), and Ikaria (Greece). People in these ‘blue zones’ tend to live longer and are less likely to have long-term diseases. But despite the geographic and cultural differences between the different ‘blue zones’, researchers identified common dietary practices among them.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/38474857/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/33925037/?ref=alphabetguides.com) The diet isn’t a rigid or prescriptive one but rather a flexible eating pattern. It is a [plant-based diet](https://www.alphabetguides.com/tag/plant-based/), with \~80-95% of calories coming from vegetables, legumes, whole grains, nuts, and fruits. This means a high intake of beans and legumes (primary protein source), olive oil and other healthy fats, and a moderate intake of fish and poultry. Red meat intake is limited (reserved for special occasions), while dairy products are also consumed in moderation (usually from goat’s or sheep’s milk or fermented forms like yoghurt and cheese). Processed food, sugars, and salt are generally kept low. The diet emphasises other eating practices as well (besides what you eat). This includes moderate portion sizes (e.g., eating until [80% full](https://www.alphabetguides.com/hara-hachi-bu-an-ancient/)), socialising while you eat, and eating at the dinner table. The positive effects seem to come from its balanced ‘macronutrient’ profile (enough protein, fat and carbohydrate), high ‘nutrient-density’, fibre content, antioxidant and anti-inflammatory foods, and low intake of [processed foods](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/). --- ## Example foods and dishes - **Breakfast:** - Porridge with walnuts, figs, & honey - Avocado whole-grain toast & tomatoes. - **Lunch**: - Minestrone with whole-grain bread - Chickpea & vegetable stew with brown rice. - **Snack:** - Handful of almonds with an apple - Hummus with crudites. - **Dinner:** - Grilled fish with roasted sweet potatoes & a mixed green salad - Lentil & vegetable curry with quinoa. - **Dessert:** Fresh fruit salad with a few squares of dark chocolate. - **Drinks:** Green tea, water & lemon, herbal tea. --- ## Pros The diet is based on the associations between diet, life expectancy, disease risk, and quality of life (particularly in older adults). The diet is rich in foods that are known to reduce inflammation, cardiovascular disease risk and improve metabolic health. The diet provides an array of nutrients, and there is very little risk of any nutrient deficiency or of consuming too much food.[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5986484/?ref=alphabetguides.com) For weight loss, plant-based ‘Mediterranean-style’ diets (like the blue zone diet) are associated with healthy body weights and lower risk of obesity, particularly when they are combined with [active lifestyles](https://www.alphabetguides.com/tag/exercise/). For weight loss, the diet is probably more sustainable than diets that eliminate entire food groups, severely restrict food intake or require calorie counting.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/28214525/?ref=alphabetguides.com) ## Cons While the story behind the blue zone diet is compelling, there’s little high-quality evidence that it works outside the regions where it’s practised. The people in the blue zones are also known to practice other healthy lifestyle habits that have little to do with their diet (e.g., social life, low work and general stress, being physically active and other cultural practices).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/38474857/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/33925037/?ref=alphabetguides.com) Following this diet can be challenging outside of the Blue Zone regions may be challenging. These regions have well-developed cultural, familial, economic, communal and agricultural systems in place, which may not be in place in other regions. The availability of food (year-round), the cost, cooking skills, free time, and social norms can create problems for some people.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/36782207/?ref=alphabetguides.com) --- ## Bottom Line The Blue Zone diet is what some of the healthiest people in the world follow. It is a whole food, plant-based diet, which provides excellent nutrition and few safety concerns. However, in our opinion, it lacks high-quality evidence showing that it works (on a mass scale) for people outside these regions. In theory, the diet should be suitable for people who want a flexible, sustainable diet that’s good for their general health and healthy ageing. However, it does require some social support, cooking skills and other lifestyle changes to be successful. --- ## Overall Score: **★★★★☆** - Health Benefits: **★★★★☆** - Nutrition: **★★★★☆** - Weight Control: **★★★★☆** - Ease to Follow: **★★★★☆** - Safety Profile: **★★★★★** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

URL: https://www.alphabetguides.com/an-apple-a-day-keeps-the-doctor-away-a-review/ Last updated: 2026-09-02T17:24:21.000Z summary - Apples contain a unique combination of fibre, polyphenols, and vitamins that support heart health, blood sugar control, appetite and gut health. - The evidence is solid. But eat them whole with the peel on. Juice loses the fibre and most of the beneficial compounds. - An apple a day won't keep every doctor away, but it earns its place in a healthy diet. Cheap, available, and nutritious — the proverb largely holds. The proverb “an apple a day keeps the doctor away” suggests that regular consumption of apples supports health and prevents diseases. This article examines the evidence for how apples contribute to [nutrition and well-being](https://www.alphabetguides.com/tag/nutrition/). While they may not have had access to modern scientific instruments, today we do. So does this cheap, humble fruit live up to its reputation? Believe it or not, researchers have investigated whether this proverb is true. They analysed data from nearly 8,400 American adults to test whether apple eaters actually avoided doctor visits.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/25822137/?ref=alphabetguides.com) While daily apple eaters did show a tendency toward fewer doctor’s visits (39% of apple eaters avoided visits vs 34% of non–apple eaters), it wasn’t conclusive and was likely to be due to something else (alongside eating an apple a day). But before you abandon your daily apple, the researchers did report that apple eaters were less likely to be on prescription medication. So maybe “an apple a day keeps the medication at bay” is a more accurate reflection of the data. ## Are apples good for you? The magic of apples lies in their impressive nutritional profile, which can help contribute to your overall health. A medium apple contains essential vitamins, minerals, and lots of antioxidant plant compounds called polyphenols. Several key polyphenols have been identified in apples, like catechins, hydroxycinnamic acids, and quercetin. The compound 'phloridzin' is particularly noteworthy, as it's almost exclusively found in apples (and related species). The apple peels contain the highest concentration of these beneficial compounds, particularly the red-skinned apples.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/15140261/?ref=alphabetguides.com) Recent studies show that red-fleshed apple varieties can contain up to six times more anthocyanins than white-fleshed varieties, which may explain their superior antioxidant values. Beyond polyphenols, apples provide dietary fibre, with about 2-3% total fibre content. Approximately 70% of this is insoluble fibre, while the remaining 30% consists mainly of pectin, a soluble fibre linked to digestive health and potentially lowering blood cholesterol levels. The fruit also delivers modest amounts of vitamin C, potassium, and trace minerals like zinc and iron, contributing to daily nutrient intake. ## Health benefits of apples A study found that eating antioxidant-rich apples improved blood vessel health in people at risk for cardiovascular disease. The soluble fibre in apples has been shown to help prevent cholesterol buildup in artery walls, while the potassium content also helps support healthy blood pressure levels.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/29086478/?ref=alphabetguides.com) Despite containing natural sugars, apples have a low glycemic index. High consumption of apples (and pears) was associated with a lower risk of type 2 diabetes. The polyphenols in the apple are thought to help manage blood glucose levels and improve insulin sensitivity.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/28186516/?ref=alphabetguides.com) Apple intake can also help [weight loss](https://www.alphabetguides.com/tag/fat-loss/), with the high fibre and water content (apples are about 85% water) helping promote fullness, without the calories.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/12620529/?ref=alphabetguides.com) While no single food *prevents* cancer, apples’ polyphenol content shows promise, being associated with a lower risk of several cancers (like colorectal, breast and digestive tract). Perhaps the most consistent finding across studies is apples' ability to combat oxidative stress and inflammation. These two processes fuel many chronic diseases. Research shows that consuming apples can reduce inflammation in overweight and obese adults.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/34105575/?ref=alphabetguides.com) Apples can also positively impact your gut bacteria. The pectin fibre and polyphenols interact with gut microbiota, promoting beneficial bacterial species. This may explain some of apples' metabolic benefits, as a healthy gut microbiome has been shown to influence everything from immune function to mental health.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/26016654/?ref=alphabetguides.com) ## Eat the whole apple! One critical finding needs highlighting: whole apples appear far superior to the apple juice. Juice lacks the fibre found in whole fruit, and many beneficial nutrients concentrate in the peel. So, apple juice is no substitute for the whole thing.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/38052651/?ref=alphabetguides.com) --- ## Apple and cinnamon overnight oats ### Ingredients (serves 2) - 1/2 cup (90 g) rolled oats - 3/4 cup (180 mL) water, milk, plant milk or mix - 1 medium apple, diced (keep the peel on) - Optional: 1 tsp chia seeds, ½ tsp cinnamon, 1 tbsp walnuts, 1 tsp honey ### Directions 1. Combine all ingredients in a jar or container. 2. Stir well, cover, and refrigerate overnight. 3. In the morning, stir again and enjoy cold, or warm in the microwave for a minute or two. 4. The oats absorb the moisture, while the apple pieces provide texture and natural sweetness. ![bowl of oatmeal topped with chopped green apples](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/photo-1559329607-43c470fd9aac.jpeg) --- ## Spinach and apple salad with tahini dressing ### Ingredients (serves 2) - 4 cups fresh spinach - 2 medium apples, thinly sliced - 2 tbsp tahini - Juice of 1 lemon - 1 tbsp extra virgin olive oil - Optional: ½ cup (30 g) pumpkin seeds and dried cranberries ### Directions 1. Mix spinach with sliced apples, pumpkin seeds, and cranberries. 2. Whisk together tahini, lemon juice, and olive oil 3. Add water gradually until you reach the desired consistency. 4. Season the dressing and drizzle it over the salad, and toss gently. --- ## Baked apple “doughnut” ### Ingredients (serves 2) - 2 large apples, cored and sliced into rings - 2 tbsp almond or peanut butter - Optional: 1 tbsp ground flaxseed, a pinch of cinnamon ### Directions 1. Preheat oven to 350°F (175°C). 2. Bake the apple rings for 10–12 minutes until slightly softened but not mushy. 3. Remove from oven and let cool slightly. 4. Spread nut butter on each apple ring and sprinkle with healthy toppings (e.g., flaxseed and cinnamon). --- ## Bottom Line So, does an apple a day truly keep the doctor away? Probably, but not by itself. There is good evidence suggesting that eating whole apples (and whole fruit in general) is beneficial for your health. Apples contain a unique combination of fibre, vitamins, minerals, and phytonutrients, which cannot be replicated by a supplement, or possibly even a mixture of other healthy foods. But for best practice, eat them whole with the peel on. While an apple a day, alone, will not guarantee you stay out of the hospital, it certainly has its place in a healthy diet. Looks like the proverb pretty much holds. Apples are cheap, readily available, tasty and come in their own natural, healthy edible packaging that keeps them edible for weeks. --- #### Sources 1.

But there are negatives to longer fasts. - Fasting responses vary significantly by age, health status, and duration, and extended fasting requires medical supervision. ## What Is Fasting? Fasting is defined as the voluntary 'abstention' from food for a period of time. When you do it, it goes on to trigger a load of changes in your body. This article explains how the body responds during fasting based on scientific research. When you skip a meal, whether by choice, for religious reasons, or as part of a purposeful [intermittent fasting](https://www.alphabetguides.com/intermittent-fasting-diet/) routine, your body starts a fascinating journey of change throughout your entire body. ## Hours 0–4: Digestion and Blood Sugar (The Postprandial Phase) In the first few hours after eating, your body is still processing your last meal. Your pancreas releases insulin to help move carbohydrates (your blood sugar or glucose) into cells to use for energy. Any excess carbohydrate gets stored in your liver and muscles as a substance called 'glycogen'. During this “postprandial” period, your digestive system is working flat out, and your blood sugar levels are elevated. Your gut, liver, and pancreas are all coordinating to extract nutrients from food and distribute them throughout your body as quietly and efficiently as possible. ## Hours 4–18: Glycogen Depletion Begins (Early Fasting) As you move past the 3-4 hour mark, things start to change. Your [blood sugar and insulin](https://www.alphabetguides.com/fasting-and-diabetes/) levels begin to decline, and your body starts converting glycogen back into glucose.[\[1\]](https://www.ncbi.nlm.nih.gov/books/NBK534877/?ref=alphabetguides.com) Your body wants to keep your blood sugar levels as steady as possible, with what it has available. So when your levels start to drop, your liver will start breaking down that stored glycogen and release it into your blood, which delivers it to the rest of your body. Most of your glycogen is stored in your liver and in your muscles. You usually have enough to keep you going for about 24 hours of your normal daily activity. But once your carbohydrate stores start running low, your pancreas reduces the amount of insulin it releases and starts increasing production of another hormone: glucagon. Glucagon acts in the opposite way that insulin does. It tells your body to release stored energy rather than store it. Your blood glucose levels remain relatively stable during the 'early fasting' period, though they're lower than in the 'postprandial' period. If you do not fast regularly, you may notice changes to your focus, mood, or energy levels during this time. However, there doesn't appear to be any drop-off in your ‘cognitive performance’ during short-term fasts.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/41182703/?ref=alphabetguides.com) ## Hours 18–24: Fat Burning Begins (The Fuel Switch) Around the 18-24-hour mark, your liver's glycogen stores are becoming depleted, which forces a major “metabolic” fuel switch. At this point, your body fat ('adipose tissue') starts releasing stored fat (as 'fatty acids') into your bloodstream to be used for energy (“lipolysis”). Some of these fuels are converted by your liver into another type of fuel: 'ketone bodies', which are small molecules that can be used for energy instead of fat.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/29086496/?ref=alphabetguides.com) This ‘fuel shift’ from mainly burning carbohydrates (and fat) to burning ketones (and fat) is called ‘[ketosis](https://www.alphabetguides.com/keto-diet/)’. It is defined as an increase in blood ketone levels, which can take 24-72 hours to occur. However, in addition to fat, your body also starts breaking down protein (from your muscles) and converts it into carbohydrate for energy (a process called 'gluconeogenesis'). This can be as much as half a kilogram of muscle mass a day when you factor in water and your glycogen stores. There are also some (relatively minor) changes in your cardiovascular system, where your heart rate increases, and your blood pressure decreases.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/39747857/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/35380473/?ref=alphabetguides.com) ## Hours 24-72: The Ketogenic Period This is when fasting's effects on the brain become particularly interesting. Lower glucose levels are thought to trigger a ‘cleaning operation’ in your brain cells (via a process called 'autophagy'), which may be beneficial for [brain health](https://www.alphabetguides.com/tag/brain-health/) and cognitive function.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/34579042/?ref=alphabetguides.com) Many people also report better mental clarity during this phase, where your brain’s using ketones for fuel. During this time, your cells also become more sensitive to insulin, and inflammation and oxidative stress can also decrease in those who have high levels to start with. Your gut bacteria are also thought to respond positively by increasing the amount of beneficial “good” bacteria and decreasing the harmful “bad” bacteria.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/38410639/?ref=alphabetguides.com) ## Hours 72+: The Extended Fasting Period These types of fasting are only done under medical supervision, as the changes that occur become more dramatic. These changes can be both positive and negative for health, depending on your baseline health status (where you’re starting from). [Autophagy ‘clean-up’ continues](https://www.alphabetguides.com/autophagy-and-fasting/), which is thought to support healthy ageing and help protect brain health. You continue breaking down muscle for energy, and you also continue to burn fat and lose body weight. Over a 7-day water fast, a group of young healthy adults lost 4.6 kg of muscle mass, 1.4 kg of fat and 5.8 kg of body weight. This could have both positive and negative effects on your health, depending on your starting point and health goals.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/39747857/?ref=alphabetguides.com) Most of your major hormones start to change when you fast for this long, both the amount of them and how they interact with your body. There are also some reported benefits to your immune system as well.[\[8\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC11560338/?ref=alphabetguides.com)[\[9\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC7474734/?ref=alphabetguides.com) --- ## Frequently Asked Questions _This post is for subscribers only._ ### DASH Diet: A Review URL: https://www.alphabetguides.com/dash-diet/ Last updated: 2026-09-22T10:16:30.000Z summary - The diet was developed to combat hypertension through specific nutrient goals and restricting sodium to under 2.3g a day. - People who follow the diet can meaningfully and safely reduce their blood pressure, cardiovascular disease and diabetes risk. - Real-world adherence is a challenge as cost, cooking requirements, and food culture limit sustained uptake of the diet. The ‘DASH’ diet (short for ‘Dietary Approaches to Stop Hypertension’) was developed by the National Institutes of Health in the 1990s to prevent and treat hypertension (i.e., high blood pressure). Following positive results from high-quality studies, the diet has been used to improve [cardiovascular health](https://www.alphabetguides.com/tag/heart-health/) and for weight loss.[\[1\]](https://www.ncbi.nlm.nih.gov/books/NBK482514/?ref=alphabetguides.com)[\[2\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5509411/?ref=alphabetguides.com) The diet is based on eating fruits, vegetables, whole grains, low-fat dairy products, nuts, and legumes, while limiting saturated fat, cholesterol, sodium, red meat, and added sugar. The DASH diet recommends 4–5 servings of fruits and vegetables daily, 6–8 servings of whole grains, 2–3 servings of low-fat dairy, and moderate amounts of lean meat, fish, nuts, and seeds. The restriction of sodium to 1.5-2.3 grams a day is a key part of the diet. The diet's macronutrient content is moderate protein, relatively low fat (particularly saturated fat), and higher intake of ‘complex’ carbohydrates from whole foods. The diet aims to provide high levels of key micronutrients, which work together to support healthy blood pressure and reduce inflammation (e.g., potassium, magnesium, calcium, and fibre). --- ## Example foods and dishes - **Breakfast:** - Low-fat yoghurt with granola, blueberries, & banana - Whole-wheat toast with peanut butter & an orange - **Lunch:** - Turkey sandwich on whole-grain bread with lettuce, tomato, and mustard - Quinoa bowl with grilled chicken, mixed veg, & low-sodium dressing - **Snack:** - Apple slices with almond butter - Low-fat cottage cheese with cucumber slices - **Dinner:** - Baked chicken breast, brown rice, steamed broccoli, & salad leaves - Baked cod with roasted sweet potato & green beans - **Dessert:** Fresh berries with low-fat Greek yoghurt - **Drinks:** Herbal tea, skim milk --- ## Pros Several high-quality studies have shown that the DASH diet improves cardiovascular and metabolic health. It reduces the risk of heart failure and type 2 diabetes. It lowers blood pressure, blood sugar levels, and improves blood lipid profiles. Emerging studies also suggest other health benefits, like improved liver health for those with liver disease and potential improvements in migraines and [mental health](https://www.alphabetguides.com/tag/mental-health/).[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6413235/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/23466047/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/26503843/?ref=alphabetguides.com) The diet is nutrient-rich, high in fibre, potassium, calcium, magnesium, and antioxidants (from [plants](https://www.alphabetguides.com/tag/plant-based/) and low-fat dairy). Studies have shown that people who follow the diet meaningfully increase their intake of the key nutrients with a *low* risk of any deficiencies. The diet has been shown to help with sustainable weight loss and fat loss, alongside other health benefits.[\[1\]](https://www.ncbi.nlm.nih.gov/books/NBK482514/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/26503843/?ref=alphabetguides.com) ## Cons Although the diet has proven health benefits, how well and how long people are able to follow the diet is a concern. Food costs, personal preferences, and social eating are problems for some people. Translating recommendations into sustainable real-world (‘tried and tested’) dietary practice proves difficult for many diets, including the DASH diet.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/18268173/?ref=alphabetguides.com) Recommended foods, particularly fresh produce, lean proteins, and low-fat dairy products, can be expensive, and the diet may also require planning, preparation skills, and cooking time, which can be a problem for some people.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/18268173/?ref=alphabetguides.com) Some groups of people have cultural traditions or preferences for high-sodium (salty) foods. The emphasis on [low-fat dairy](https://www.alphabetguides.com/low-fat-diet/) and whole grains may not suit everyone. This also means the diet may not be suitable for people with lactose intolerance or *some* kidney issues.[\[1\]](https://www.ncbi.nlm.nih.gov/books/NBK482514/?ref=alphabetguides.com) --- ## Bottom Line The DASH diet represents one of the best-supported diets available, with *strong* evidence for improving cardiovascular health, metabolic health, and lowering overall disease risk. The primary issues with the diet are the lack of long-term real-world adherence rates, but this doesn’t mean that it isn’t viable either. Real-world adherence to the diet depends heavily on education, outside support, affordability, and cultural fit. But for those able to maintain it, the DASH diet offers a comprehensive guide to good nutrition and long-term health. The DASH diet is suitable for *nearly* all types of people, especially people with cardiometabolic health issues, and it poses minimal health risks. --- ## Overall Score: **★★★★★** - Health Benefits: **★★★★★** - Nutrition: **★★★★★** - Weight Control: **★★★★☆** - Ease to Follow: **★★★☆☆** - Safety Profile: **★★★★★** - [Scoring System](https://www.alphabetguides.com/diet-scoring-system/) --- #### Sources 1.

Faster rates increase muscle loss, nutrient deficiencies, and weight regain. - Protein intake of 1.6–2.4g per kg of bodyweight daily during a calorie deficit reduces loss of muscle compared to lower protein intakes. - Even proven "fat-burning" supplements only burn 100 extra calories, whereas dietary and exercise interventions routinely exceed 1,000. Weight loss and fat loss are the overall reduction in body mass and body fat, respectively. It is usually achieved through dietary, activity, and lifestyle changes. This article addresses the most commonly asked questions about these processes and what the evidence says about them. ## 1\. How can I lose weight quickly? A safe rate of fat loss is about 0.5-1 kg (or 1–2 lbs) a week. Research shows that gradual weight loss results in more fat being lost and preserves your muscle and metabolic rate better compared to rapid weight loss.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/32576318/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/21558571/?ref=alphabetguides.com) Faster rates of weight loss risk greater muscle wasting, nutritional deficiencies, and metabolic adaptations that increase the likelihood of regaining the lost weight. The exception is people with severe obesity or related conditions who need to lose weight fast for their health. This is done under medical supervision. ## 2\. How many calories should I eat to lose fat? Calorie counting is not strictly required, but creating a "calorie deficit" is likely needed to lose fat. Tracking calories may help some people achieve consistent results, as it provides awareness and accountability. However, you can create a calorie deficit (and lose fat) through other strategies like portion control, [eliminating processed foods](https://www.alphabetguides.com/how-to-avoid-upfs/), increasing protein and fibre intake, or eating mindfully. The method matters less than the outcome (consuming [fewer calories](https://www.alphabetguides.com/eat-to-lose-fat/) than you burn). Some people succeed with intuitive approaches, while others benefit from precise tracking. Choose the method you can sustain long-term. [What to Eat to Lose Weight and Body FatCalorie counting only gets you so far. Protein intake and food quality decide whether a fat-loss and energy deficits actually sticks.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-179ac923-e49e-4a22-9bd4-758f1b1b5233.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1610415946035-bad6fc9f5b8e-8369e7ab-dd1b-40b6-b39a-094445033fa8.jpg)](https://www.alphabetguides.com/eat-to-lose-fat/) ## 3\. Can I target belly fat through specific exercises? No, you probably can’t selectively burn ‘subcutaneous’ body fat from specific areas of the body through targeted exercise. Where the fat loss occurs throughout the body is largely determined by [genetics](https://www.alphabetguides.com/fat-genes/) and hormones, not which muscles you exercise. While some research suggests you **can** target fat loss around your abdomen, other studies have not. However, you can certainly change the 'proportion of fat' (i.e., % fat) of any region of the body by increasing the amount of muscle you have there.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/38010201/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/23222084/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/17596787/?ref=alphabetguides.com) Exercising a certain region of the body may not burn the fat directly from that region, but it can strengthen and add muscle to that area, giving the appearance that you have lost fat or “toned” that area. ## 4\. What type of exercise is best for fat loss: cardio or strength training? Both have important but different roles. Aerobic exercise burns more calories during the activity itself, making it more efficient at creating a calorie deficit and improving your cardiovascular health. [Strength training](https://www.alphabetguides.com/resistance-training-beginners/) preserves and builds muscle mass, which maintains your metabolic rate while you lose weight and improve your body composition (i.e., % body fat).[\[6\]](https://pubmed.ncbi.nlm.nih.gov/35191588/?ref=alphabetguides.com) The optimal approach seems to combine both [aerobic exercise](https://www.alphabetguides.com/what-are-training-zones/) for energy expenditure and strength training for your muscles. This combination provides additive benefits that neither achieves alone. [Move It to Lose It: Exercise & Activity for Fat LossExercise has a powerful role in weight and fat loss. Here we look at high-intensity interval training, aerobic training, weightlifting and NEAT.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-d678e301-8aa3-4863-befb-6e7f31a4163f.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1590771982343-dd3783c27410-7907a5ee-36ae-475b-a934-bb4d0d0019ab.jpg)](https://www.alphabetguides.com/exercise-fat-loss/) ## 5\. Can I lose fat through diet alone without exercise? Yes, fat loss is possible through [diet alone](https://www.alphabetguides.com/fat-loss-diets/), since weight loss fundamentally requires a calorie deficit. You can achieve this deficit entirely by reducing your food intake. However, adding exercise provides significant advantages: it increases total energy expenditure, preserves muscle mass, improves [cardiometabolic health](https://www.alphabetguides.com/exercise-lowers-blood-pressure/), enhances insulin sensitivity, and supports long-term weight maintenance.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/33955140/?ref=alphabetguides.com) Diet-only approaches often result in greater muscle loss alongside fat loss. For optimal body composition and health outcomes, combining moderate calorie restriction with [regular physical activity](https://www.alphabetguides.com/exercise-fat-loss/) produces superior and more sustainable results than diet alone.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/7713045/?ref=alphabetguides.com) ## 6\.

Hara hachi bu prevents overeating that leads to bloating, fatigue and obesity. - Hara hachi bu is not a diet — it's a mindset shift. Slow down, use smaller plates, remove distractions, and let your body catch up. “Hara Hachi Bu” is a Japanese principle that advises eating until you're 80% full to maintain good health. This article explores its benefits and how it can support healthy eating habits and body weight. If you feel sluggish, bloated, or uncomfortable after meals, you may be eating past the point your body actually needs. This centuries-old Japanese principle offers a simple solution: “Eat until you are no longer hungry, not until you are full”. The practice, known as hara hachi bu, has been part of Japanese "Okinawan" culture for generations. It is as far from a modern diet trend as can be. It is a deliberate "mindful" approach to eating that supports healthy ageing, long-term [weight control](https://www.alphabetguides.com/tag/fat-loss/), and general health. ## What is Hara Hachi Bu? (and where does it come from?) Hara hachi bu (腹八分目) translates directly to “belly 80% full". It encourages you to stop eating a meal before reaching fullness; it treats food as nourishment rather than entertainment, a reward, or emotional clutch. The principle is deeply embedded in [Okinawan daily life](https://www.alphabetguides.com/bokinawa-diet/). Older generations traditionally recite the phrase before meals as a reminder to eat mindfully and moderately. Historically, the practice evolved during periods of food scarcity, when careful rationing was needed. Like most good innovations, it comes from necessity. Over time, practitioners have developed strategies such as chewing thoroughly, using smaller plates, and pausing mid-meal became normal. These habits are now thought to contribute to some of the best health outcomes in the world. ## Hara hachi bu and the Okinawan Blue Zone Okinawa is one of the world's recognised “[Blue Zones](https://www.alphabetguides.com/blue-zone/)” — regions where people live the longest, healthiest lives. Okinawa Island has roughly 60 centenarians per 100,000 residents (three times more than the US), and Okinawan elders also maintain exceptional health well into their 80s and 90s. Rates of heart disease, diabetes, cancer, and dementia are much lower than in the West. Lifestyle factors such as strong community ties and daily movement matter as well, but diet is consistently cited as a primary driver of their health. Hara hachi bu, combined with a nutrient-dense, [plant-based](https://www.alphabetguides.com/tag/plant-based/) eating pattern, appears central to traditional Okinawan health and longevity. ## What does the science say about eating until 80% full? Hara hachi bu functions as a natural form of moderate calorie restriction, a practice that has been well studied. Okinawans traditionally consumed about 1,900 kcal per day, which is roughly 10-25% less than most recommendations, and over half of what Americans actually eat (\~3,800 kcal a day). Importantly, they achieved this without strict dieting or hunger — they simply stopped eating a bit earlier than they'd like. Scientific evidence supports the health benefits of this approach. Calorie restriction without malnutrition has been shown to improve cardiometabolic health, reduce oxidative stress, and promote healthy ageing.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/27544442/?ref=alphabetguides.com) Research on traditional Okinawan diets shows that mild, long-term calorie restriction combined with nutrient-dense foods is linked to longer life expectancy and lower age-related death rates compared with the (already relatively healthy) mainland Japanese people.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/20234038/?ref=alphabetguides.com) These findings suggest that consistent, moderate reduction in your energy intake — achieved through mindful eating practices (such as hara hachi bu) — may support healthy ageing. --- ## How to know when you're 80% full When your stomach starts filling with food, it starts to expand (and stretch). There are "stretch receptors" in your stomach that sense this and send an "I'm getting full" signal to your brain, which stops you from eating. "Satiety hormones" from your gut (e.g., CCK, PYY, GLP-1, GIP) are released when there's food in it, telling you "I'm full." Release of hunger hormones like ghrelin is also decreased at the same time, making you less hungry. These changes take about 20 minutes.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/20122136/?ref=alphabetguides.com) If you eat soft, processed foods quickly until you feel "full", you have probably already overshot your body's needs — bypassing these satiety signals. By the time your appetite hormone signals reach your brain, you've overeaten, and discomfort or drowsiness often sets in. Stopping at 80% full aligns more closely with your true physiological needs. Ten to twenty minutes after the meal ends, most people feel comfortably satisfied rather than "stuffed". Hara hatchi bu can prevent this overshoot. ## Can hara hachi bu improve longevity? Although a healthy body weight is a natural outcome of hara hachi bu, there are other benefits besides the number on the scale. - **Reduced oxidative stress**: Overeating accelerates oxidative stress, a process in which "free radicals" damage cells and tissues. People who practice moderate calorie restriction exhibit lower oxidative stress markers, which are associated with a lower risk of cardiovascular disease and certain cancers.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/8658196/?ref=alphabetguides.com) - **Improved metabolic health**: Moderate calorie reduction improves your insulin sensitivity, fat metabolism and reduces inflammation. These changes significantly lower your risk of type 2 diabetes and gaining fat.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/31303390/?ref=alphabetguides.com) - **Better digestive health**: Smaller meals reduce the work the digestive system has to do. It minimises [bloating](https://www.alphabetguides.com/fodmap/) and may improve nutrient absorption. Many people report greater afternoon alertness and fewer post-meal crashes in energy levels. - **Cognitive function**: Emerging evidence links lower calories to improved cognitive function in ageing, potentially lowering dementia risk. - **Meal satisfaction**: Paradoxically, eating less can increase the enjoyment of food. When eating becomes mindful rather than automatic, flavours and textures are more noticeable, and satiety arrives sooner. ## How to practise Hara Hachi Bu in everyday life: practical strategies The principle is simple, but applying it consistently takes practice. The following tips hopefully make it easier in a modern environment that encourages overeating. _This post is for subscribers only._ ### Carnivore Diet: A Review URL: https://www.alphabetguides.com/carnivore-diet/ Last updated: 2026-09-22T10:17:01.000Z summary - The carnivore diet is an all-animal diet that eliminates every plant food and has near-zero carbohydrate intake, which induces a state of ketosis. - The evidence is limited to self-reported data, with weight loss being the most common benefit. - It eliminates fibre and several essential micronutrients, carries potential health risks, and has a questionable long-term safety profile. The carnivore diet is a low-carbohydrate diet that eliminates all [plant foods](https://www.alphabetguides.com/tag/plant-based/) and consists exclusively of animal products (e.g., [meat, eggs,](https://www.alphabetguides.com/mediterranean-meat-dairy/) fish, and sometimes limited dairy). Proponents of the diet claim it addresses various health issues (like inflammatory, digestive, and metabolic conditions) by removing certain plant compounds they consider problematic; fibre, lectins, phytates, and oxalates are commonly cited examples. The diet's core principle is a simple, meat-only eating pattern. Vegetables, fruits, grains, legumes, nuts, seeds, and plant-based oils are banned. Followers typically eat beef, pork, poultry, fish, and eggs as their staples, with some people including organ meats for specific nutrients. Water and occasionally bone broth serve as primary fluids, while coffee and tea are included in some forms of the diet (but not others). Unlike other low-carbohydrate diets that allow some vegetables, the carnivore diet maintains zero (or near-zero) carbohydrates. So, like other very low-carbohydrate diets, it induces a metabolic state of ‘ketosis’, where the body uses fat (and ketones) for fuel instead of carbohydrates. --- ## Example foods and dishes - **Breakfast:** - Fried eggs cooked in butter with bacon - Ground beef patties fried in tallow. - **Lunch**: - Grilled ribeye steak with bone marrow - Half a rotisserie chicken (skin on). - **Snack:** - Beef jerky - Hard-boiled eggs with salt - **Dinner:** - Lamb chops with beef liver pâté - Slow-cooked pot roast, fatty cuts preferred. - **Dessert:** Whipped cream (for those including dairy). - **Drinks:** Black coffee, water, bone broth. --- ## Pros *Current* evidence for the benefits of the carnivore diet is taken from self-reported survey data rather than clinical research. Therefore, reported benefits should be treated with caution. People who follow the diet have reported high satisfaction levels and *perceived* improvements in their body weight, health and well-being.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/34934897/?ref=alphabetguides.com) People with diabetes have reported health improvements, with some noting decreases in medication use. People with bowel conditions also reported improvements in their gut function when following the diet.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/39296504/?ref=alphabetguides.com) The reported weight loss people experience (who are already overweight or obese) probably comes from the diet’s high-protein content and complete elimination of [junk foods](https://www.alphabetguides.com/health-effects-of-ultra-processed-foods-an-overview/) and sugar. The diet's simplicity may appeal to those of us who get overwhelmed by overly complex dietary guidelines. Its restrictive nature might be easier to follow for people who like clear rules and boundaries.[\[3\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC9964047/?ref=alphabetguides.com) ## Cons The carnivore diet presents several concerns that limit its appeal. The elimination of all plant foods raises issues around the adequacy of certain nutrients (e.g., vitamin C, folate, pyridoxine, fibre, calcium, and magnesium). Another potential worry is the lack of diversity of food, which is important for a healthy gut “microbiome”. A low diversity of the bacteria in your gut is associated with inflammation, obesity, gut, immune and [mental health ](https://www.alphabetguides.com/tag/brain-health/)issues.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/32833688/?ref=alphabetguides.com)[\[5\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC10229385/?ref=alphabetguides.com) There’s also some debate around whether the high intake of animal (saturated) fat, with some studies reporting increases in the “bad” LDL cholesterol, increases [cardiovascular disease](https://www.alphabetguides.com/tag/heart-health/) risk. The low fibre intake has been flagged as an issue for your gut health, and the high protein intake can *possibly* affect bone health and the function of some of your internal organs.[\[6\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC9964047/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/39796574/?ref=alphabetguides.com) The restrictive nature of the diet also creates practical, social, and ‘psychological’ challenges. This includes the high cost of the high-quality animal foods, the limited variety and availability of them, and the potential effect on social eating or dining out. While motivated people report high short-term adherence to the diet, the real-world sustainability of the diet for most people is questionable. --- ## Bottom Line The carnivore diet represents one of the most restrictive and unproven diets out there for improving your health and body weight. While there’s *some* data suggesting *some* people experience short-term satisfaction and perceived health benefits, the evidence is weak. There are also concerns about the nutritional adequacy of the diet, the cardiovascular risks and its unknown long-term safety. --- ## Overall Score: _This post is for subscribers only._ ### Ketogenic Diet: A Review URL: https://www.alphabetguides.com/keto-diet/ Last updated: 2026-09-22T10:16:44.000Z summary - The ketogenic diet is a very high-fat, very low-carbohydrate diet that induces "ketosis", switching your body's fuel source to ketones. - It is good for short-term weight loss, epilepsy symptoms, and metabolic health improvements in people with epilepsy, obesity or type 2 diabetes. - The diet is nutritionally restrictive, difficult to sustain long-term, and possibly increases cardiovascular disease risk. The ‘ketogenic’ diet is a high-fat, very low-carbohydrate, moderate-protein diet. The classic ketogenic diet consists of about 70-90% of calories from fat, 6-10% from protein, and only 2-10% from carbohydrates, limiting it to 20-50 grams a day. The *very* low-carbohydrate intake forces you into a ‘metabolic state’ called ketosis. This is where the liver converts fat into ketones that are used as an alternative source of energy. The diet was originally developed in the 1920s as a treatment for epilepsy. Since then, it has gained mainstream popularity for its weight loss and health benefits. After about 2–4 days of *very* low-carbohydrate intake, your carbohydrate stores become depleted, and the body increases the amount of fat it uses for fuel. The liver then starts to produce ketones, which the brain and other tissues use as fuel when carbohydrates aren’t around to use. The main foods on the ketogenic diet are: fatty meats, fish, eggs, full-fat dairy products, nuts, seeds, oils (particularly coconut and [olive oil](https://www.alphabetguides.com/superfood-olive-oil/)), butter, avocados, and low-carbohydrate vegetables (e.g., [leafy greens](https://www.alphabetguides.com/superfood-leafy-greens/) and cruciferous vegetables). Grains, most fruits, starchy vegetables (e.g., potatoes and corn), legumes, sugar, and most [processed foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/) are banned (or severely restricted). Eating even small amounts of carbohydrates can take you out of ketosis, so you have to pay special attention to the amount of carbs you’re eating. --- ## Example Foods and Dishes - **Breakfast:** - Coffee & butter with scrambled eggs & avocado - Full-fat Greek yoghurt with mixed nuts & seeds - **Lunch:** - Bunless cheeseburger with bacon & coleslaw - Cobb salad with chicken, bacon, eggs, and blue cheese dressing - **Snack:** - Pork rinds with guacamole - "Fat bombs" (coconut oil, cream cheese, cocoa powder) - **Dinner:** - Pork chops with mashed cauliflower with butter & cheese - Baked salmon with zucchini noodles in Alfredo sauce - **Dessert:** Keto cheesecake (almond flour crust) - **Drinks:** Black coffee & cream, unsweetened iced tea --- ## Pros The ketogenic diet leads to quick [weight loss](https://www.alphabetguides.com/tag/fat-loss/) and metabolic health benefits, particularly for people who’re already obese and/or have type 2 diabetes. The ‘initial’ weight loss on the keto diet (i.e., first 6 to 12 months) is a bit quicker than most other diets. However, after a year, there doesn’t appear to be any weight loss benefits.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC10210275/?ref=alphabetguides.com) The ‘metabolic health’ benefits are also well-documented. People who follow the diet have reported improved blood sugar and blood lipid profiles. People with type 2 diabetes experience substantial improvements in health, sometimes allowing their medication to be reduced (under close medical supervision). The diet also leads to notable increases in the good “HDL” cholesterol and decreases in blood triglycerides (important markers of [cardiovascular health](https://www.alphabetguides.com/tag/heart-health/)).[\[2\]](https://pubmed.ncbi.nlm.nih.gov/36012064/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/33882506/?ref=alphabetguides.com) Beyond the cardiometabolic health benefits, the diet remains an effective treatment for drug-resistant epilepsy. There’s strong evidence suggesting it reduces seizures in both children and adults. Emerging research suggests there are *some* potential benefits for the gut microbiome, as well as some neurological conditions.[\[4\]](https://www.ncbi.nlm.nih.gov/books/NBK499830/?ref=alphabetguides.com) ## Cons The diet's [very low carbohydrate intake](https://www.alphabetguides.com/atkins-diet/) can limit intake of dietary fibre, several vitamins and minerals (e.g., B vitamins, vitamin C, magnesium, and potassium), and other nutrients found in [plants](https://www.alphabetguides.com/tag/plant-based/) and whole grains. Without careful planning (and probably supplementation), this could lead to nutrient deficiencies and increase disease risk.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/34336911/?ref=alphabetguides.com) A common concern is the elevated low-density lipoprotein (‘LDL’) cholesterol that is reported in a lot of people who follow the diet. This raises questions about long-term cardiovascular health risk despite improvements in other blood lipids.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/31805451/?ref=alphabetguides.com) There are also well-known side effects, sometimes called the ‘keto flu’, which include fatigue, headaches, irritability, constipation, nausea, and muscle cramps. However, these typically stop within days or weeks of following the diet. The more serious potential complications include kidney stones, nutrient deficiencies, and gut problems. In practice, maintaining the diet can be difficult. The diet's highly restrictive nature, high cost, limited food choices, and social barriers make the diet (relatively) difficult to follow long-term. A lot of people struggle to stay in ketosis without education and support from someone who knows what they are doing.[\[4\]](https://www.ncbi.nlm.nih.gov/books/NBK499830/?ref=alphabetguides.com) --- ## Bottom Line The ketogenic diet is effective for short-term weight loss and metabolic health improvements, particularly for people who are overweight, obese, and have type 2 diabetes. However, concerns remain about its effects on cholesterol levels, nutrient content, how easy it is to follow, and long-term health risks. --- ## Overall Score: _This post is for subscribers only._ ### Does Testosterone Build Muscle? URL: https://www.alphabetguides.com/testosterone-and-muscle-growth/ Last updated: 2026-09-04T13:33:14.000Z summary - Testosterone builds muscle — but pharmaceutical doses work differently from what you can achieve naturally. - Training, sleep, diet, and body fat all affect testosterone activity. Poor sleep alone can cut levels by 15% in a week. - More testosterone isn't always better — it's about avoiding clinically low levels, which genuinely harm your muscle, energy, and health. Testosterone is a hormone that plays a key role in muscle growth, strength, and body composition. This article examines how your natural testosterone levels affect your [muscles](https://www.alphabetguides.com/tag/muscle/) and the scientific evidence. It's revered as the ultimate muscle-building hormone ('vitamin T'), but what can be realistically achieved naturally? Spend enough time in the gym, on fitness blogs or around athletes, and you'll hear about “boosting T levels” through supplements, specific foods, or different types of training. But [what actually affects testosterone](https://www.alphabetguides.com/testosterone-blueprint/)? Or does it even matter if it does? The relationship between testosterone and muscle growth is undeniable. However, the difference between *naturally* increasing your testosterone levels and*pharmaceutically* increasing them is vastly different — far more than most people realise. Understanding this distinction is crucial for setting realistic expectations and making informed decisions about your training and health goals. This article looks at what testosterone actually does in the body, how it influences muscle growth, the natural decline that occurs with ageing, and evidence-based strategies to support it. ## How does testosterone build muscle? ### The master regulator Testosterone is a steroid hormone produced primarily in the testes (in specialised cells called 'Leydig' cells) in males, and to a much lesser extent in the adrenal glands and ovaries in females. In men, approximately 95% of testosterone production is controlled by “luteinizing hormone”, which is released from the pituitary gland in the brain. While testosterone is known for regulating male sexual characteristics and fertility, its role in muscle growth is equally important. Testosterone functions as a "master regulator" of muscle mass and muscle growth. It controls the rate at which your body synthesises new proteins, which are the fundamental building blocks of muscle. This biological process, referred to as “muscle protein synthesis”, determines whether your muscles grow, maintain their size, or shrink. Higher testosterone levels accelerate this process, creating a more favourable environment for growth. ### The evidence? The muscle-building effects of testosterone aren't theoretical; they're demonstrated clearly and consistently. Many studies have shown that administering testosterone as a drug substantially increases muscle growth, whether combined with exercise or not. A landmark study on testosterone divided a group of men into four groups: one group did no exercise, another group did no exercise and injected testosterone (600 mg of testosterone enanthate a week), another group just did [weightlifting exercise](https://www.alphabetguides.com/minimalist-muscle-growth/) (no testosterone injections), and another group exercised and took testosterone1. The men receiving testosterone without any exercise gained more muscle mass than men who exercised without testosterone. The group that combined testosterone with exercise gained the most muscle of all, about 6 kg in just 10 weeks! Even in clinical settings where testosterone is used as replacement therapy ("TRT") at relatively modest doses to restore levels to normal ranges, it still triggers muscle growth. These findings confirm that testosterone in its pharmacological form powerfully stimulates muscle growth. No doubt. ### Testosterone and other hormones Testosterone doesn't operate in isolation. It works together (in a "stack") with other muscle-building hormones, including growth hormone and insulin-like growth factor-1 (IGF-1). These hormones have overlapping and complementary effects, amplifying each other's muscle-building ability. This creates a more powerful anabolic environment than any single hormone could achieve alone. --- ## Natural vs. synthetic testosterone Here's where expectations meet reality. The presence of natural testosterone in your body is fundamentally different from what occurs when testosterone is administered as a therapeutic or performance-enhancing drug. When testosterone is injected or applied "transdermally" (through the skin), it creates sustained, very high levels of free testosterone in the bloodstream — often 600% or more above natural levels. These elevated concentrations remain consistently high throughout the day and night, providing continuous anabolic signalling to muscle tissue for hours or days. In contrast, natural testosterone levels tend to fluctuate throughout the day. Healthy men experience peak testosterone levels in the morning, with concentrations gradually declining over the day. These peaks in testosterone last *minutes* to maybe a few hours rather than days or weeks. Natural testosterone levels, even when optimised through [lifestyle factors](https://www.alphabetguides.com/testosterone-blueprint/), remain within a relatively narrow range. This distinction is critical: changes in natural testosterone levels within the normal "physiological" range do not appear to impact muscle growth anywhere near as much as pharmacological doses do, if they impact muscle growth at all!.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/11701431/?ref=alphabetguides.com) Research comparing men with naturally higher versus naturally lower testosterone (but both within normal ranges) shows small differences in muscle-growth capacity, but nothing to really write home about. ## What does this mean for natural lifters? _This post is for subscribers only._ ### Mediterranean Diet: A Review URL: https://www.alphabetguides.com/mediterranean-diet-review/ Last updated: 2026-09-22T10:15:57.000Z summary - The Mediterranean diet is a flexible, plant-based diet built around olive oil, fish, vegetables, legumes, and whole grains. - It is consistently linked to lower rates of cardiovascular disease, type 2 diabetes, certain cancers, and brain and mental health disorders. - But fresh fish, olive oil, and seasonal food can be costly outside Mediterranean regions; adapting it requires some effort. The [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/) is based on the traditional eating habits of people who live in the Mediterranean (e.g., Greece, Southern Italy, and Spain). Rather than a prescriptive set of rules, it is a flexible eating pattern that’s based on [plant foods](https://www.alphabetguides.com/mediterranean-one-pot/), healthy fats, and moderate consumption of fish and poultry, while limiting red meat and processed foods. Extra virgin [olive oil](https://www.alphabetguides.com/superfood-olive-oil/) is the main fat source; it is rich in monounsaturated fats and antioxidants that are good for your heart and metabolism. [Fish and seafood](https://www.alphabetguides.com/superfood-oily-fish/) are eaten at least twice a week. Poultry, eggs, and dairy products, particularly yoghurt and cheese, are consumed in moderate amounts. Red meat and sweets are only occasionally eaten. Some traditional versions of the diet include a glass of red wine with meals, though this is optional and not necessary for its health benefits. The diet’s high fibre content, antioxidants, and omega-3 fatty acids help reduce inflammation and support general health. The emphasis on unprocessed whole foods also provides nutrients without the extra calories. The diversity of [plant foods](https://www.alphabetguides.com/tag/plant-based/) is also good for your gut microbiome and gut health.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/34423871/?ref=alphabetguides.com) Beyond its nutritional content, the diet also incorporates other healthy lifestyle habits (which are often overlooked). This includes being physically active, resting a lot, regularly socialising and sharing meals with other people. The combination of high-quality food, healthy eating behaviours, flexibility and a relaxed lifestyle distinguishes it from most diets. --- ## Example foods and dishes - **Breakfast:** - Greek yoghurt with honey, walnuts, & fresh figs - Whole grain toast with olive oil, tomatoes, & feta - **Lunch:** - Greek salad with chickpeas, olives, feta, cucumber, tomatoes, olive oil dressing - Tuna Nicoise with beans, olives & tomatoes - **Snack:** Olives & almonds *or* Whole-grain crackers with tzatziki - **Dinner:** - Baked chicken with roasted veg (eggplant, zucchini, peppers) & couscous - Seafood paella, saffron rice, mussels, shrimp, & peas - **Dessert:** Fresh fruit salad with a small piece of baklava - **Drinks:** Espresso, water with lemon, red wine --- ## Pros Studies consistently show that those who follow the diet have substantial reductions in [cardiovascular disease](https://www.alphabetguides.com/tag/heart-health/), including lower rates of coronary heart disease and stroke.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/29897866/?ref=alphabetguides.com) Beyond cardiovascular health, there is evidence linking the diet to reduced risk of type 2 diabetes, certain cancers (such as colorectal and breast), and ‘neurodegenerative’ diseases (like dementia and Alzheimer’s disease). The diet is associated with lower overall death rates, with benefits also shown for people outside the Mediterranean regions.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/28488692/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/24931280/?ref=alphabetguides.com)[\[5\]](https://pubmed.ncbi.nlm.nih.gov/12826634/?ref=alphabetguides.com) People who follow the diet tend to maintain healthy body weights and lose weight if they are already overweight. There is a reduced risk of weight (re) gain over time, so it’s not a yo-yo diet.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/18635428/?ref=alphabetguides.com) The diet is rich in nutrients and provides a balanced macronutrient profile. The abundant fibre, vitamins, minerals, and antioxidants mean there is minimal risk of any nutrient deficiencies. Improved quality of life, enhanced physical and [mental well-being](https://www.alphabetguides.com/tag/brain-health/) and healthy ageing are also reported alongside the other health benefits. ## Cons Whilst the Mediterranean diet's evidence base is robust, there are some practical limitations. The cost of the diet can present barriers outside Mediterranean regions, where olive oil, fresh fish, and out-of-season produce may be expensive, although there are [ways around it](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/). Accessibility to some ingredients may be a problem in some areas of the world, where the food environments favour processed, convenience foods over fresh, whole foods. Some aspects of the diet may be difficult for people with different culinary ‘traditions’, though the diet's flexibility generally means it can be adjusted to locally available foods and cultural preferences. The initial unfamiliarity with Mediterranean-style cooking skills and [recipes](https://www.alphabetguides.com/mediterranean-diet-meal-plan/) may also be challenging for some people.[\[7\]](https://pubmed.ncbi.nlm.nih.gov/36296998/?ref=alphabetguides.com) The moderate wine consumption part of the diet has been flagged for people who have issues with alcohol (e.g., a history of addiction, certain medications, or religious/personal preferences for abstinence). However, alcohol is *not* essential, and non-drinkers can adopt all other aspects of the diet and get the same (possibly better) health benefits. --- ## Bottom Line The [Mediterranean diet](https://www.alphabetguides.com/mediterranean-diet-guide/) represents one of the most well-studied and strongly supported diets for disease prevention and overall health. Its excellent safety profile, nutritional adequacy, and flexibility make it suitable for most populations and age groups, with particularly strong evidence for cardiovascular protection and longevity.[\[8\]](https://pubmed.ncbi.nlm.nih.gov/30817261/?ref=alphabetguides.com) --- ## Overall Score: _This post is for subscribers only._ ### Paleo Diet: A Review URL: https://www.alphabetguides.com/paleo-diet/ Last updated: 2026-09-22T10:15:34.000Z summary - Based on the hunter-gatherer diet. It includes meat, fish, eggs, and plants, while excluding grains, legumes, dairy, and all processed foods. - Short-term weight loss and modest metabolic improvements are reported, likely due to removing processed foods and added sugar. - Excluding dairy, grains, and legumes raises risks of some deficiencies, increases the cost of food, and may adversely affect gut health. The ‘Paleo’ diet, also known as the Palaeolithic, caveman, or Stone Age diet, is based on the premise of eating foods that were **presumed** to be available to our hunter-gatherer ancestors during the Palaeolithic era. This is the era that ended around 10,000 years ago, just before organised agriculture got going. Proponents of the diet argue that modern humans remain genetically adapted to the Paleo diet and that recently introduced, commercially produced foods contribute to modern-day diseases (as they do not align with our biology).[\[1\]](https://www.ncbi.nlm.nih.gov/books/NBK482457/?ref=alphabetguides.com)[\[2\]](https://pubmed.ncbi.nlm.nih.gov/10918987/?ref=alphabetguides.com) The diet's core principle involves consuming foods that were hunted and gathered, which means it excludes foods that emerged from industrial farming (plants or animals). Permitted foods include lean meats, fish, seafood, eggs, vegetables, fruits, nuts, and seeds. The diet excludes grains (e.g., wheat, rice, oats, barley), legumes (e.g., beans, lentils, peanuts), dairy products, refined sugars, [processed foods](https://www.alphabetguides.com/ultra-processed-food-diet/), vegetable oils, and salt. Some versions of the diet allow butter, fermented foods, or some oils (e.g., coconut or [olive oil](https://www.alphabetguides.com/superfood-olive-oil/)). The diet promotes higher protein intake (around 20-35% of calories), moderate to high fat intake (around 30-50%), and lower carbohydrate intake (around 20-40%). Its elimination of [processed foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/), added sugars, and refined carbohydrates is good for your health. However, the classification, definition, and current availability or form of foods that are considered “paleo” are widely debated. --- ## Example foods and dishes - **Breakfast:** - Scrambled eggs with roast veg & avocado - Sweet potato hash, ground beef, & peppers - **Lunch:** - Grilled chicken salad with mixed greens, veggies, & olive oil dressing - Lettuce-wrapped burger with roast sweet potato fries - **Snack:** - Apple slices with almond butter - Raw veggies with guacamole - **Dinner:** - Grilled salmon with roasted Brussels sprouts & cauliflower rice - Beef stir-fry with zucchini noodles & coconut aminos - **Dessert:** Fresh berries with coconut cream - **Drinks:** Black coffee, herbal tea --- ## Pros The Paleo diet has some short-term benefits for [cardiometabolic health](https://www.alphabetguides.com/tag/heart-health/). Improvements in blood pressure, blood lipid profile and blood sugar are reported in people who already have metabolic health issues or type 2 diabetes. However, these improvements may simply result from eliminating and reducing processed food, added sodium and sugar rather than the paleo diet in itself.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/26269362/?ref=alphabetguides.com)[\[4\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC6628854/?ref=alphabetguides.com) People who follow the diet lose [weight and body fat](https://www.alphabetguides.com/tag/fat-loss/). This is probably a result of the diet’s high protein content and the elimination of calorie-dense processed food; removing both of these from your diet will increase fullness and reduce calorie intake.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/31337389/?ref=alphabetguides.com) ## Cons There are concerns about the Paleo diet's nutritional content. Excluding entire food groups, particularly dairy, whole grains, and legumes, can increase the risk of deficiencies like calcium, vitamin D, fibre (especially resistant starch) and some other micronutrients. The alterations in your gut microbiome are also unfavourable. There are also links between the high intake (or excessive) of [red meat](https://www.alphabetguides.com/carnivore-diet/) and cardiovascular disease risk.[\[6\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC4997304/?ref=alphabetguides.com)[\[7\]](https://pubmed.ncbi.nlm.nih.gov/31273523/?ref=alphabetguides.com) The diet's restrictive nature tends to limit the diversity of the foods you eat, and can be challenging to follow. People who follow the diet report struggling with the food restrictions, higher costs of the diet, and problems eating out or at social gatherings. The exclusion of more affordable nutrient-dense foods like [beans, lentils, whole grains](https://www.alphabetguides.com/plant-based-protein/) and dairy increases the cost of the diet, so it’s not viable for some people. There are also some concerns about bone health because of the elimination of dairy (calcium and vitamin D). --- ## Bottom Line The Paleo diet offers short-term weight loss and modest metabolic health improvements. This seems to come from eliminating unhealthy foods. However, [gut health](https://www.alphabetguides.com/fodmap/) concerns. The [big positives](https://www.alphabetguides.com/the-3-worst-diet-what-to-avoid/) for the diet are the removal of ultra-processed foods, emphasis on whole foods and higher protein, rather than mimicking eating like our ancestors. --- ## Overall Score: _This post is for subscribers only._ ### Intermittent Fasting: A Review URL: https://www.alphabetguides.com/intermittent-fasting-diet/ Last updated: 2026-09-22T10:14:25.000Z summary - Intermittent fasting restricts when you eat rather than what you eat, either using daily eating "windows" or "fasting days". - Weight loss and health benefits of intermittent fasting are similar (or marginally better) compared to standard calorie-restriction diets. - Intermittent fasting may not be suitable for everyone, as health and safety outcomes vary in different groups of people. Intermittent fasting is a dietary pattern that alternates between periods of eating and periods of [fasting](https://www.alphabetguides.com/tag/fasting/); you focus on *when* to eat rather than *what* to eat. Unlike traditional diets that tend to focus on reducing the amount of calories you eat, intermittent fasting limits the time that you eat, which creates extended periods of time when you aren’t eating. These types of fasts aren't new; they have roots in a number of religious and cultural practices. However, they’ve recently gained attention from scientists and (then) mainstream popularity for their potential health benefits. There are many [types of intermittent fasts](https://www.alphabetguides.com/types-of-intermittent-fasts/). ‘Time-restricted eating’ limits daily food intake to a specific window (e.g., 6-10 hours), while fasting for the rest of the day. ‘Alternate-day fasting’ involves regular eating days and fasting (or severe calorie restriction) on alternate days. An example is the 5:2 diet that permits normal eating for five days a week while restricting food intake to 500-600 calories a day on two non-consecutive days. During the fasting period, the [body shifts](https://www.alphabetguides.com/the-fasting-timeline-what-happens-to-your-body-hour-by-hour/) from using carbohydrates for fuel to fat (and then ketones during longer fasts). This metabolic ‘shift’ typically occurs after 12–16 hours into the fast. Some scientists have suggested that this process may activate cellular repair processes (called ‘autophagy’), normalise blood sugar levels, and reduce inflammation. Many people find fasting appealing because it doesn’t overtly restrict specific foods or require calorie counting. --- ## Example foods and dishes - **Breakfast:** - Black coffee or tea (during fasting window, no food) - Water with electrolytes (during fasting window, no food) - **Lunch:** - Large mixed salad with grilled chicken, avocado, nuts, olive oil (breaking fast) - Burrito bowl with rice, beans, meat, cheese, guacamole (first meal) - **Snack:** - Mixed nuts & an apple (during eating window) - Cheese & crackers (during eating window) - **Dinner:** - Salmon with roasted veg & sweet potato - Pasta with meat sauce, salad leaves, & garlic bread - **Dessert:** Ice cream or cookies (during eating window) - **Drinks:** Black coffee, tea, sparkling water --- ## Pros Intermittent fasting is associated with several health benefits. It results in weight loss, comparable to traditional calorie-restriction diets, alongside improved [body composition](https://www.alphabetguides.com/tag/fat-loss/) and metabolic health markers.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/31614992/?ref=alphabetguides.com) Intermittent fasting can help normalise blood pressure, [blood sugar](https://www.alphabetguides.com/fasting-and-diabetes/) and blood lipid profiles in people who already have high levels. Improved control of appetite and beneficial changes to the gut microbiome have also been reported.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/37024596/?ref=alphabetguides.com)[\[3\]](https://pubmed.ncbi.nlm.nih.gov/28715993/?ref=alphabetguides.com) The structured eating schedule may help some people control their calorie intake without the constant vigilance required by other (more traditional) calorie-restriction diets.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/35194176/?ref=alphabetguides.com) ## Cons While the health benefits are obvious, intermittent fasting doesn’t seem to be superior to other standard calorie-restriction diets. Different people also seem to respond differently to fasts, with some people meaningfully improving their health, while others don’t seem to respond as well. There are no clear indicators at the moment for who may (or may not) benefit from intermittent fasts. There have also been questions about the long-term sustainability of intermittent fasts (and their health benefits), and whether some people may have problems getting all the essential nutrients they need in shorter eating windows.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/37242218/?ref=alphabetguides.com) There are also some practical challenges. A lot of people struggle with hunger when starting intermittent fasts; fatigue, irritability, headaches and gut problems have also been reported.[\[6\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC5959807/?ref=alphabetguides.com) A strict fasting schedule can also conflict with family meals, social gatherings, work tasks, or some cultural practices. Shift workers, people with irregular work patterns, and [those who’re exercising](https://www.alphabetguides.com/should-you-exercise-fasted/) a lot may find intermittent fasting difficult. Intermittent fasting is also not recommended for certain people, including pregnant or breastfeeding women, people with histories of eating disorders (where rigid eating rules may trigger disordered eating patterns), children and adolescents, and people with certain medical conditions requiring regular food intake. --- ## Bottom Line Intermittent fasting is (in most cases) a safe, effective approach for [weight loss](https://www.alphabetguides.com/fasting-and-weight-loss/) and improving metabolic health, with benefits comparable to traditional calorie-restriction diets. However, the sustainability and the variable responses suggest it is one effective option among several, rather than the sole dietary solution to health. --- ## Overall Score: _This post is for subscribers only._ ### 3 Underrated Ways to Lose Fat URL: https://www.alphabetguides.com/3-underrated-ways-to-lose-fat/ Last updated: 2026-09-02T16:56:28.000Z summary - Increasing dietary protein reduces hunger, burns more calories through digestion, and preserves muscle during fat loss with minimal effort. - Resistance training preserves (and builds) metabolically active muscle tissue, which prevents metabolic slowdowns that cause plateaus and weight re-gain after dieting. - Walking is free, sustainable, and effective; 7,000–10,000 steps a day can burn the energy equivalent of roughly one kilogram of fat every six weeks. Fat loss is the process of reducing body fat through sustainable [changes to diet,](https://www.alphabetguides.com/fat-loss-diets/) activity, and lifestyle. This article explains three evidence-based methods that are often overlooked but effective for long-term fat loss results. Instead of doing simple things that work, people tend to gravitate towards dramatic, fancy options. Extreme diets, punishing workouts, expensive supplements, and 'revolutionary' innovations dominate headlines and social media. But never seem to work in the long-run, and disappear as quickly as they arrived. Meanwhile, some of the most effective, sustainable, and evidence-based things you can do remain quietly in the background, delivering consistent results for those who follow them. These underrated strategies don't promise an overnight transformation (because they don't). But they'll create meaningful, lasting changes to your body without extreme sacrifice, unsustainable restrictions, or complicated rules. They just take time. They all have robust, high-quality scientific evidence backing them. They work together, complementing each other. And perhaps most importantly, they can be adapted to virtually any lifestyle, budget, or fitness level. Why are these strategies underrated? Partly because they lack the marketing appeal of the flashy quick fixes. Partly because they require consistency. And partly because their benefits compound gradually over time, making them less (immediately) gratifying than the more 'radical' approaches. --- ## #1\. Dietary Protein When people think of “fat loss”, they typically focus on cutting calories, eliminating carbohydrates, or avoiding fat. Meanwhile, protein, the third macronutrient, remains overlooked, despite offering big advantages for fat loss. ### Protein increases satiety and appetite Protein increases feelings of fullness. [High-protein meals](https://www.alphabetguides.com/high-protein-diet/) produce greater 'satiety' compared to high-carbohydrate meals with the same amount of calories. Protein intake stimulates the release of appetite-suppressing gut hormones (e.g., GLP-1, PYY, and CCK) and suppresses the release of the "hunger hormone" (ghrelin).[\[1\]](https://pubmed.ncbi.nlm.nih.gov/25926512/?ref=alphabetguides.com) These hormonal changes begin within minutes of eating protein and can last for hours, keeping you feeling fuller for longer. So, by increasing your protein intake, you'll naturally eat less without having to rely on willpower or conscious restrictions. Studies show that people who increase protein intake throughout the day tend to consume [fewer calories](https://www.alphabetguides.com/eat-to-lose-fat/) in total. ### Protein increases the thermic effect of food Your body burns calories just digesting and processing the food you eat. This process is called “diet-induced thermogenesis” (DIT), and protein has the highest by far. Somewhere between 20–30% of the calories in the protein you eat get used to digest and process it. Compare this to under 3% for fat and 5–10% for carbohydrates. This means that of every 100 calories of protein you eat, only 70–80 kcal are actually available for your body to use. Whereas 97 out of 100 calories of fat are available to either burn or store. Although this might seem like a relatively small amount of calories, it does compound over time, especially if protein comprises a large portion of your daily calorie intake. More importantly, it requires little extra time or effort other than eating the protein itself. ### Protein preserves muscle When you restrict calories, your body needs to find the energy from somewhere. It can break down fat stores (the best option for health!). But it can also break down muscle tissue to use for energy. Unfortunately, calorie-restricted diets often result in losing both [fat and muscle](https://www.alphabetguides.com/body-recomposition-lose-fat-gain-muscle/). Research shows that people who consume high amounts of protein during weight loss lose less muscle (and sometimes none at all). Why does this matter? Because muscle tissue is "metabolically active". This means it burns energy continuously just to maintain itself. A kilogram of muscle burns around 13 calories a day. This is 2-3 times more than fat tissue does. So, preserving muscle means you'll maintain a higher '[metabolic rate](https://www.alphabetguides.com/basal-metabolic-rate/)', burn more calories and make fat loss easier. ### How much protein do you need? The optimal amount of protein depends on your physical activity level, current body composition, and your fat loss goals. However, research provides some [guidance](https://www.alphabetguides.com/nutrition-and-body-recomposition/). To preserve muscle while aiming to lose fat, aim for 1.5–2.4 g/kg/day. So, for a 100 kg person, this translates to 150–240 g/day, or roughly 30–50 g per serving, across three to five meals or snacks throughout the day. Most people can target the lower end of this range. Whereas older adults, those who are physically active and have a lot of muscle already (e.g., athletes), should aim towards the upper end of the range. ### How to eat enough protein While total daily protein intake is the primary goal, it is easier to spread it throughout the day. Start by increasing protein intake by 10–20 g/day until reaching your daily target. This gradual approach can prevent digestive problems and allow your appetite to adjust naturally. Batch cooking [protein-rich foods](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/) like grilled chicken, hard-boiled eggs, or legume dips saves time and eliminates decision-making. Have convenient, ready-to-eat protein available for when you're busy and hungry. Canned fish, protein powders, Greek yoghurt, and pre-cooked lean meats are cheap and affordable options if cost is a concern.

Resistance Training When people think about exercise for fat loss, they envision hours of cardio: running, cycling, or elliptical machines. Meanwhile, [resistance training](https://www.alphabetguides.com/resistance-training-beginners/) remains overlooked as it is associated with bodybuilding and athletic performance rather than fat loss. This represents a fundamental misunderstanding of how weightlifting affects your body. ### Muscle-metabolism connection As we said before, muscle tissue is metabolically active. It continuously burns energy just to maintain itself, even while you're sleeping or sitting at a desk. When you lose weight through diet alone or with low-moderate intensity cardio exercise, you tend to lose both fat and muscle, especially if you're not eating enough protein. Losing muscle will therefore impact your metabolic rate. Every kg of muscle lost means fewer calories burned, making fat loss harder (it's known as 'adaptive thermogenesis' or 'metabolic adaptation'). This explains why many dieters hit frustrating plateaus or rapidly regain weight after losing it. Weightlifting (and dietary protein intake) changes this equation by preserving existing muscle mass, or potentially adding new muscle tissue. People who lift weights while dieting lose [less muscle and more fat](https://www.alphabetguides.com/resistance-training-body-recomposition/).[\[2\]](https://pubmed.ncbi.nlm.nih.gov/18356845/?ref=alphabetguides.com) ### Body composition vs. scale weight The bathroom scale often fails to reflect the positive changes that happen when you incorporate weightlifting into your fat loss programme. You might lose a kg of fat while simultaneously gaining a kg of muscle. The scale wouldn't change, but your body fat percentage, waist circumference, strength, and physical appearance will. This simultaneous process of losing fat while gaining muscle is called "[body recomposition](https://www.alphabetguides.com/body-recomposition-lose-fat-gain-muscle/)", and it should be the actual goal for anyone wanting to lose fat rather than just "lose weight." So, instead of obsessing over scale weight, [focus on other things](https://www.alphabetguides.com/beyond-the-scale/): progress photos, how clothes fit, belt notches, and strength improvements in the gym. Waist circumference provides a particularly useful measure, as humans tend to lose fat from the abdominal region while gaining muscle around the appendages (i.e., legs and arms). ### Weightlifting vs. cardio: different tools, different outcomes While cardiovascular exercise burns more calories during the activity itself, weightlifting provides superior, longer-term benefits. The “afterburn effect” (formally called "excess post-exercise oxygen consumption") can increase your metabolic rate for hours after a weightlifting session. The process of repairing your muscles and growing them also requires energy for days after your workout. This doesn't mean cardio has no value (because it does!). It's just that weightlifting provides unique advantages that cardio cannot replicate, so it is advised alongside, not instead of, other forms of exercise. ### Getting started: practical advice You don't need expensive equipment or gym memberships to start. Begin with 'compound' body weight exercises like squats, push-up variations, lunges, planks, and other core exercises. It's possible to build and maintain muscle using just your body weight, especially when you're new to resistance training (so no excuses!). Start with at least two weightlifting sessions per week, allowing each muscle group at least 2 days of recovery between sessions. If you're new to weightlifting or haven't been physically active, master basic movement first before adding weights. Learning proper form prevents injury and ensures you're targeting the intended muscles efficiently. The key is consistency over time. The health benefits and body composition changes from weightlifting compound slowly but effectively over weeks, months, and years. Read our other articles for more detailed advice.

Pair them with grains to optimise nutrition. - Canned tuna and boiled eggs are the fastest and cheapest animal protein options. Adding them to salads for a nutritious meal in minutes. All five [recipes](https://www.alphabetguides.com/tag/recipes/) in this article contain at least 15g of protein per serving and cost under $1 to make — using traditional Mediterranean ingredients like lentils, chickpeas, fava beans, eggs, and canned tuna. [High-protein](https://www.alphabetguides.com/high-protein-diet/) Mediterranean dishes regularly combine flavourful, nutrient-dense ingredients and have their own health benefits. However, some people assume it’s expensive, elitist, difficult to access or difficult to cook. In reality, this couldn't be further from the truth. Most traditional Mediterranean dishes were born from “cucina povera” or *“*peasant cooking”. This means simple meals built from cheap ingredients and cheap proteins. These foods are nutritious, plant-based, high in protein, fibre, and affordable. Below are five high-protein Mediterranean dishes you can make for under $1 per serving. --- ## #1\. Greek fakes (lentil soup) Greek Fakes(pronounced fah-KESS) is one of the best-loved “everyday” dishes in Greece. It's an earthy lentil soup enjoyed for generations. Lentils have been part of [Mediterranean diets](https://www.alphabetguides.com/mediterranean-diet-guide/) since antiquity. They are valued for their long shelf life, low-cost, and high protein content. Along with lentils, Fakes relies on other humble ingredients like onion, tomato, and olive oil, simmered together. Its high protein content comes entirely from the lentils, making it an option for those seeking [plant-based protein](https://www.alphabetguides.com/plant-based-protein/). They're cheap, filling, and rich in fibre, iron, and antioxidants. It embodies how traditional Mediterranean diets achieve nutrition from simple foods. ### Ingredients - Brown or green lentils - Onion - Carrot - Garlic - Tomato paste or crushed tomato - Dried Herbs: Thyme, Oregano, Bay leaf - Olive oil - Vegetable stock or bouillon ### Directions 1. Dice and sauté the onion, carrot, and garlic in a small amount of olive oil. 2. Add lentils, tomatoes, and herbs. 3. Crush the tomatoes in the pan with a wooden spoon. 4. Cover with vegetable stock and simmer until the lentils are soft (\~45 minutes). 5. Season and finish with a splash of red wine vinegar, olive oil and crusty bread. --- ## #2\. "Pasta e Ceci" (Italian chickpea and pasta stew) Pasta e Ceci (CHEH-chee) is a classic Italian dish from the central and southern regions, especially Rome and Campania. Historically, a poor man’s dish, it combines [pantry staples](https://www.alphabetguides.com/7-pantry-essentials-for-the-mediterranean-diet/) — chickpeas, garlic, rosemary, and pasta. This dish is high in quality plant-protein thanks to the combination of chickpeas and pasta, and offers "slow-release" carbohydrates and fibre. Its creamy texture comes from simmering the chickpeas until they break down naturally and thicken the sauce. Because every ingredient is cheap and shelf-stable, Pasta e Ceci is one of the best Mediterranean diet meals for anyone cooking on a budget. ### Ingredients - Canned or cooked chickpeas - Small pasta (ditalini, elbows, penne) - Garlic - Olive oil - Tomato or tomato paste - Vegetable stock or bouillon - Rosemary ### Directions 1. Slice the garlic and sauté it with the rosemary in olive oil. 2. Add chickpeas and a little tomato purée or whole tomatoes. 3. Pour in the vegetable stock and simmer for a few minutes. 4. Add pasta and cook until tender (\~10 minutes). 5. Season and mash some chickpeas and mix them into the liquid to thicken the stew. --- ## #3\. "Ful Medames" (North African fava bean stew) "Ful Medames" is one of the oldest documented dishes in the Med. It has been eaten in Egypt for thousands of years and is still a [breakfast staple](https://www.alphabetguides.com/mediterranean-breakfast-ideas/) across the Eastern Mediterranean. It is traditionally cooked in large clay pots, containing slow-simmered fava beans mixed with lemon, garlic, cumin, and olive oil. Fava beans (or broad beans) are one of the [highest-protein legumes](https://www.alphabetguides.com/legumes-and-health/). With beans costing pennies, and the remaining ingredients just basic flavourings, it is one of the most cost-effective high-protein meals around. _This post is for subscribers only._ ### The 3 Worst Diets for Your Health URL: https://www.alphabetguides.com/the-3-worst-diet-what-to-avoid/ Last updated: 2026-09-28T10:30:09.000Z summary - Bad diets promise rapid results but consistently fail. They cause nutrient deficiencies, muscle loss, weight cycling, and mental health issues. - Processed foods aren't always a conscious choice. They are engineered to drive overconsumption, and high intake of them is linked to poor health. - Knowing what a harmful diet looks like is just as important as knowing what a good one is. Recognising the red flags is your first line of defence. Unhealthy diets increase the risk of nutrient deficiencies and long-term diseases. This article looks at three common diets that consistently fail to support health and may cause you harm. Every year, millions of people waste their time, money, and energy on diets that fail to deliver promised results and can sometimes damage their health. Poor diet choices can trigger nutrient deficiencies, disrupt your metabolism, increase disease risk, and cause mental health problems, long after you’ve stopped the diet. Think about it like this: if you're navigating through a minefield, knowing where the dangers are is just as (maybe more) important as knowing a safe path through. The same principle applies to nutrition. By knowing what a harmful diet looks like (i.e., what *not* to do), you can protect yourself from setbacks. --- ## #3\. Crash diets: why rapid weight loss backfires ### What is a crash diet? Crash diets, also known as rapid weight loss diets, quick-fix diets, or [very low-calorie diets](https://www.alphabetguides.com/fasting-mimicking-diet/), represent an extreme approach to weight loss that severely restricts your calorie intake. Typically, crash dieters consume fewer than 800 calories a day. These diets have cycled through popular culture for decades, constantly reappearing with new names, new branding, but only minor variations. You might have seen them before: [juice cleanses](https://www.alphabetguides.com/juice-diet/), the cabbage soup diet, grapefruit diets, extreme meal replacement diets, or various “detox” diets promising rapid results. ### Warning signs: how to spot a crash diet [Crash diets](https://www.alphabetguides.com/crash-diet/) share a few telltale signs. They promise dramatic weight loss in short timeframes; think “lose 10 pounds in 7 days". They severely restrict your overall food intake or eliminate entire food groups. Many rely exclusively on single foods, liquids, or overpriced meal replacements. The marketing language is another giveaway. Crash diets typically use marketing rhetoric claiming to “reset your metabolism”, “flush toxins from your body”, or trigger special fat-burning “metabolic states”. These claims sound like science (that’s the point!), but they lack any legitimate scientific evidence. It's just empty words. ### The appeal and the reality The draw of crash diets is understandable. When you're frustrated with your body or have an upcoming event, a wedding, holiday, or reunion, the promise of immediate, visible results is, of course, tempting. The simplicity is also appealing to many people. Following rigid rules about exactly what to eat eliminates decision-making and can feel easier than managing full, flexible diets like the [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/). Crash diets also tend to deliver initial, rapid weight loss. This creates a sense of accomplishment, rewarding feelings and new motivation. For some people preparing for medical procedures or managing serious health conditions, rapid weight loss may be medically necessary, but it is usually done under medical supervision. This is where the benefits end, and the problems begin for most people. ### Why do crash diets cause weight regain? Consuming so few calories while drastically limiting food variety creates the risk of nutrient deficiencies. Your body requires nutrients like protein, fat, fibre, vitamins and minerals for basic bodily functions. Without adequate nutrition, these systems will begin to wobble. Most crash dieters tend to regain the weight they lost as quickly as they lost it, often exceeding their starting weight. This is a known phenomenon called “weight cycling” or “[yo-yo dieting](https://www.alphabetguides.com/yoyo-diet/)”, and it may actually worsen your health compared to maintaining a stable weight.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/18719680/?ref=alphabetguides.com) There are other side effects as well: fatigue, muscle wasting, weakness, dizziness, headaches, irritability, [poor sleep](https://www.alphabetguides.com/tag/sleep/), constipation, hair loss, menstrual cycle problems, gallstones, dehydration, and heart arrhythmia in severe cases. Beyond the physical effects, crash dieting takes a toll on your mental health. Repeated failed attempts at dieting are associated with eating disorders, negative body image, and unhealthy psychological relationships with food. Their restrictive nature, constant hunger, social isolation, and mental burden make these diets virtually [impossible to sustain](https://www.alphabetguides.com/diet-framing/) beyond a few weeks or months. Outside of professionally supervised medical emergencies, crash diets offer no long-term benefits and likely cause harm. [Crash Diets: A ReviewSevere calorie restriction for rapid weight loss and why the evidence cautions strongly against it.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-6e68487d-cc95-44de-9c1a-0a6b59cad4ee.png)Alphabet GuidesDr. Robert Davies![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1513611859016-00c2ee9e95f1-8c97aeda-c06f-40c4-bbb1-d0e43f06ebd5.jpg)](https://www.alphabetguides.com/crash-diet/) --- ## #2\. Fad diets: how to recognise and avoid them ### What are fad diets? [Extreme fad diets](https://www.alphabetguides.com/fad-diets/) represent a broad category of severely restrictive ‘crash diets’, which are largely unproven. Unlike evidence-based diets developed through scientific research, fad diets typically emerge from commercial interests, celebrity endorsements, or pseudoscientific theories. They gain popularity through sensational marketing rather than actually working. Social media has dramatically amplified their reach, particularly among young adults and teens, who are especially vulnerable to persuasive before-and-after photos and ‘influencer’ testimonials. ### Identifying fad diets Like crash diets, they often severely restrict caloric intake to under 800 calories a day. They eliminate entire food groups unnecessarily. Many fad diets are “mono-diets”, which means eating only one type of food, like grapefruit, cabbage, ice, or baby food. Extreme fad diets typically impose rigid rules without flexibility and promise rapid, dramatic results. They frequently make claims about “detoxification” or miracle cures for various health conditions. ### Why people fall for them The appeal comes largely out of desperation. People who get frustrated with gradual, sustainable approaches seek quick solutions. The marketing exploits body image concerns, cultural obsession with rapid "glow-ups", and the human desire to find simple answers to difficult problems. The initial rapid weight loss can provide gratification. Seeing dramatic changes on the scale within days creates motivation and a sense of accomplishment. However, much of this initial loss is water weight, [not fat](https://www.alphabetguides.com/beyond-the-scale/). Some people also like the rigid structure. Clear rules about “allowed” and “forbidden” foods remove uncertainty and eliminate the need for decisions. ### The problem(s) with them Like crash diets, severe restrictions create nutritional deficiencies. The type of deficiency depends on which foods are eliminated. For example, [ultra-low-carbohydrate diets](https://www.alphabetguides.com/atkins-diet/) reduce fibre and the micronutrients found in plants, legumes and whole grains. Ultra-low-fat diets will reduce the intake of fat-soluble vitamins and essential fatty acids that are crucial for your brain, hormones, and the health of your cells. Ultra-low-calorie diets risk widespread nutrient deficiencies and probably don't provide enough protein for maintaining muscle mass. Like crash diets, most fad diets tend to be unsustainable. They are commonly abandoned within weeks. Then the weight returns. Often with additional pounds, leading to recurring “weight cycling” and “yo-yo dieting”.

Ultra-processed food diets: the evidence against them ### What is the UPF diet? _This post is for subscribers only._ ### 7 Mediterranean Diet Pantry Staples (And How to Use Them) URL: https://www.alphabetguides.com/7-pantry-essentials-for-the-mediterranean-diet/ Last updated: 2026-09-16T09:20:07.000Z summary - Canned tomatoes cooked in extra-virgin olive oil deliver more nutrients (like lycopene) than fresh tomatoes — don't fear using them. - Anchovies, capers, and olives are often underutilised — they deliver omega-3s, quercetin, and monounsaturated fats and have long shelf lives. - Refrigerate or freeze nuts — at room temperature, their oils go rancid quickly, degrading nutrition and flavour. A Mediterranean pantry contains minimally processed, nutrient-rich staples. This article gives you seven essential ingredients that support health and are good for practical everyday cooking. ### Why pantry staples are the foundation of the Mediterranean diet If you've ever wondered how Mediterraneans make delicious, nutritious meals night after night without military planning or expensive ingredients, the answer lies in the pantry. Unlike the processed convenience foods that fill Western kitchens, Mediterranean staples are simple, affordable, whole foods that have nourished them for centuries. Whether you're new to the [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/), looking to save time, or improve your cooking, these staples will transform your kitchen and make healthy eating simple. --- ## #1\. Extra virgin olive oil ### What to buy Extra virgin olive oil (EVOO) is non-negotiable. It's the primary cooking fat and flavouring in the Med, so invest in as high-quality a one as you can afford. Look for oils in dark glass bottles or tins, as sunlight degrades quality. Also, look for harvest dates within the past year (should be on the back label of the bottle). You don't need the most expensive brand, but avoid the cheaper options. ### Can you cook with olive oil? High-quality EVOO *can* be used for cooking at moderate temperatures (up to 190°C/375°F), though some of the more delicate nutrients ("polyphenols") degrade with heat. For this reason, many Mediterranean cooks use a moderately-priced EVOO for everyday cooking and reserve their finest, most peppery oils for "finishing" dishes like drizzling over salads, soups, grilled vegetables, and bread. **Storage:** Keep olive oil in a cool, dark place away from heat and sunlight. A pantry cupboard works perfectly. Properly stored, EVOO maintains quality for 12-18 months, though fresher is generally better. ### Nutrition EVOO is rich in monounsaturated fats that lower the 'bad' LDL cholesterol while maintaining (or even raising) beneficial HDL cholesterol. This is the opposite of saturated fats, which raise both types of cholesterol, which makes EVOO particularly protective for [cardiovascular health](https://www.alphabetguides.com/superfood-olive-oil/). EVOO is also packed with polyphenols and vitamin E. These are powerful antioxidants that reduce oxidative stress and chronic inflammation, protect blood vessels, and prevent blood clots. This potentially reduces the risk of heart disease, age-related cognitive decline, and certain cancers. ### How to use it - Drizzle on salads, finish soups and stews with it, use it for sautéing vegetables, and roast potatoes and chicken in it. - Don't be shy; Mediterranean cooking uses olive oil liberally. A proper Greek salad gets a generous glug, not a quick drizzle. - Start by simply replacing butter or vegetable oil with EVOO when making scrambled eggs, sautéing vegetables, or dressing your morning avocado toast. --- ## #2\. Legumes (dried or tinned) **What to buy:** Stock dried chickpeas, brown or green lentils, white beans (cannellini or navy), and black-eyed peas. Keep a few cans of each as well for quick meals; they're nutritionally equivalent to dried and immensely convenient. **Storage:** Dried legumes keep for years in airtight containers in a cool, dry pantry. Older beans take longer to cook but remain safe and nutritious. Canned beans typically last 2-3 years; once opened, they should be refrigerated and used within 3-4 days. ### Nutrition: Legumes are nutritional powerhouses. They provide plant protein, dietary fibre (which supports digestive health, lower cholesterol, and blood sugar), folate, iron, magnesium, and potassium. The fibre and [protein](https://www.alphabetguides.com/5-high-protein-mediterranean-dishes-for-under-a-dollar/) combination promotes satiety, helping you feel full longer. Regular legume consumption is associated with reduced heart disease risk and healthier body weights. ### How to use them - Simmer lentils with tomatoes, carrots, and olive oil for Umbrian lentil stew. - Blend chickpeas with tahini, garlic, and lemon for hummus. - Toss white beans with tuna, celery, and olive oil for a quick protein-rich salad. - Add any cooked legume to soups, salads, or grain dishes. - Swap your usual lunchtime sandwich once a week with canned chickpeas or white beans tossed with olive oil, lemon juice, cherry tomatoes, and whatever vegetables you have around. --- ## #3\. Whole grains **What to buy:** Whole wheat pasta, brown rice, bulgur wheat, and whole wheat flour for flatbreads. Couscous (technically pasta, but quick-cooking) is useful for weeknight meals. Quinoa, while not traditionally [Mediterranean](https://www.alphabetguides.com/mediterranean-diet-foods/), fits the whole-grain vibe. **Storage:** Store in airtight containers to prevent rancidity. Whole grains keep 3–6 months at room temperature, longer if refrigerated or frozen. If you smell an off, bitter odour, discard them. ### Nutrition Unlike their refined grains (which are stripped of nutrients), whole grains retain fibre, B vitamins (niacin and thiamine), iron, magnesium, and selenium. They provide energy without spiking blood sugar levels (as much), support digestive health, and help maintain a healthy [body weight](https://www.alphabetguides.com/tag/fat-loss/). ### How to use them - Cook whole wheat pasta for a quick dinner. - Toss it with sautéed vegetables, [bitter greens](https://www.alphabetguides.com/superfood-leafy-greens/) and olive oil. - Make tabbouleh with bulgur (or quinoa for a [gluten-free](https://www.alphabetguides.com/gluten-free-diet/) option), parsley, tomatoes, and lemon. - Serve stews over brown rice or couscous. - Bake whole wheat flatbreads, which go with nearly everything. - Next time you make pasta, buy the whole wheat version instead.

Building muscle (also known as muscle "hypertrophy") works by increasing the size of your individual muscle cells, usually via [specific training](https://www.alphabetguides.com/resistance-training-beginners/) and nutritional strategies. This article explains the fundamental evidence-based muscle-building principles for beginners. The truth is, effective muscle growth follows well-established scientific principles that have been validated through decades of research and centuries of practice. You don’t need complicated programmes, expensive supplements, "secret" techniques, hacks, or fancy equipment to build muscle. In this article, we've created a short evidence-based checklist that distils muscle growth down to the fundamentals. ## How hard to train to build muscle? How close you get to your maximum capacity (sometimes referred to as "muscular failure") is one of the strongest predictors of muscle growth. Finishing the set within a few repetitions of failure is best for growth.[\[1\]](https://pmc.ncbi.nlm.nih.gov/articles/PMC7927075/?ref=alphabetguides.com) **Why Train Hard?** When you train to (or near) failure, you start to use more of your [muscle cells (or muscle "fibres")](https://www.alphabetguides.com/muscle-fibre-types/). This creates the mechanical tension needed to stimulate the most growth in the most muscle fibres possible. This doesn’t mean every set needs to be taken to complete failure, but each of your “working sets” should challenge you. ### Practical application: Aim to finish each set feeling like you could only complete 1–3 more repetitions with good form. Use measures like the RPE ("Rating of Perceived Exertion") or RIR ("repetitions in reserve") to gauge your effort level. The key here is to progressively "overload" your muscles, which just means gradually increasing the amount of work they are doing over time. This can be done by adding more weight, doing more repetitions, or doing more difficult exercises, while maintaining the same amount of (high) effort. ## How much should you train to build muscle? Volume per session also matters for muscle growth. Performing multiple sets per exercise is generally better than a single set. To achieve weekly volume targets, you’ll probably have to do at least 3 sets per muscle group per session.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/30153194/?ref=alphabetguides.com) Multiple sets allow you to accumulate greater mechanical tension and metabolic stress in the muscle — two key drivers of hypertrophy. If you have time, you can do up to 12 sets per muscle group, as long as you can still hit your target loads throughout the session. The mid-range of about 6 sets per muscle group per session using 2–3 different exercises is most common. ### Practical application: Structure your workouts to include 3–12 working sets for each major muscle group you’re targeting that day. This could be across 1–6 different exercises. This might seem lower than most recommendations, but consider that warm-up/ramp-up sets don’t count toward this total. Only sets performed at high intensity (near failure) qualify as “working sets”. Rest periods between sets should be enough to maintain performance without wasting precious time. Usually, this is 1–3 minutes, depending on personal preferences and your recovery time. ## How often do you have to train each muscle group? Weekly training volume is the total number of working sets performed per muscle group across all sessions. It is one of the strongest predictors of muscle growth; 12 to 20 sets per muscle group per week will optimise muscle growth for most people.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/35291645/?ref=alphabetguides.com) This range allows an adequate growth stimulus while avoiding "excessive" fatigue, which just prolongs recovery and wastes time (without adding any extra muscle growth). Beginners may start to see good results with even lower volumes. Older adults may benefit from higher weekly volumes. ### Practical application: Track your weekly sets for each major muscle group. Remember that “compound” movements (e.g., deadlift, squat, bench press) count as multiple muscle groups being worked at the same time. ## What is the best training split for muscle growth? Training frequency (how often you train each muscle group) also seems to affect muscle growth. Training each muscle group 2 (or more) times a week is better than once a week.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/30558493/?ref=alphabetguides.com) If you train more often, you can also distribute your weekly volume across multiple sessions. This allows for more recovery, which generally means better training performance and technique, and thus more efficient muscle growth. ### Practical application: Design your training split to hit each muscle group at least twice per week. This could be: - 2 full-body sessions (2 sessions total) - 1 lower body + 1 upper body + 1 full body (3 sessions total) - 2 upper body + 2 lower body (4 sessions total) This advice may contrast with the traditional 1 muscle group per week split. However, remember that the number of sets per muscle group per session is lower (as few as three). Also, remember that multiple muscle groups can (and should) be worked in a single session, and compound exercises count as working more than 1 muscle group at a time. ### How many muscle groups are there? There are over 600 muscles in the human body, and scientists have grouped them in dozens of different ways. There is no grand consensus. So, for movement and muscle growth, it might be useful to think about splitting your body into 4 major muscle parts. Divide your body into the upper body and the lower body (split at the waist). Then divide your upper and lower body into pulling and pushing muscle groups again. 1. Bench press, overhead press, dips and triceps extensions are upper-body push movements that target the chest, shoulders and triceps. 2. Rows, pull-ups, hang power cleans and bicep curls are upper-body pull movements that target your back and biceps. 3. Squats, leg press and calf raises are lower-body push movements that target your quadriceps and calves. 4. Deadlifts and hamstring curls are lower-body pull movements that aim to target your hamstrings and glutes. If you're doing big compound free-weight movements, you're rarely working any muscle group in complete isolation. Some "push" exercises (e.g., bench press) also work "pull" muscles (e.g., lat muscle), although to a lesser degree. Some muscles (e.g., glutes and abs) are fully working in both "push" and "pull" exercises (e.g., squat and deadlift). So, splitting the body up this way is not an exact science; it is just a way to ensure that you're working all major muscle groups, every week, somewhat equally. ## How long to rest to build muscle? Recovery between training sessions is crucial for growth. The muscle growth processes remain elevated for 24+ hours after training. So, an [adequate amount of rest](https://www.alphabetguides.com/rest-and-body-composition/) is needed for repair and growth to occur optimally. Training a muscle repeatedly whilst it is fatigued and sore can impair growth, increase injury risk and lead to [overtraining](https://www.alphabetguides.com/overtraining-how-to-diagnose-prevent-it/). [Delayed onset muscle soreness](https://www.alphabetguides.com/doms/) (DOMS) is an indicator of incomplete recovery, although simply "not having any DOMS" doesn't mean you are fully recovered either. Persistent soreness, poor performance, or feelings of fatigue may indicate that you're not getting enough rest. ### Practical application: If you're training at a high level of effort, allow 1 full day (or at least 48 hours) between training sessions. There is little point in training for growth when fatigued or sore. So if you trained your chest on Monday morning, avoid heavy pressing movements until Wednesday afternoon. If you are still sore and unable to hit the target weights on Wednesday, stop, do something else, and give yourself more time to rest. A bit of light movement and active recovery are fine and can actually be beneficial, but avoid any high-intensity training of the exercised muscles. Track your performance and soreness levels. If you’re consistently weaker or experiencing persistent soreness, consider adding an extra rest day or reducing training volume temporarily. ## How much sleep do you need to build muscle? Sleep is when the majority of muscle growth occurs. During deep sleep, anabolic hormone levels peak, muscle growth processes accelerate, and the repair processes run at full pace. [Poor sleep impairs muscle growth](https://www.alphabetguides.com/sleep-for-muscle/) and your recovery (which goes on to impair your growth prospects further). Quality matters as much as quantity. Sleep should be continuous, deep, and restorative. Poor sleep quality can blunt the anabolic response to training, even if the total amount of sleep appears adequate. ### Practical application: Read our full (free) evidence-based articles on optimising your sleep, which cover what to eat and what to do for better sleep, how long, what position, and what to look out for. [SleepSleep is your body’s essential recovery period. It’s when your brain clears waste, your heart rests, your hormones and your brain reset themselves.![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/icon/Logo--Square--1-4e356869-30b7-4baa-b090-ac9351f17c87.png)Alphabet Guides![](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/thumbnail/photo-1529435022610-ccc7cab8499e-d53ff186-6f42-4891-8bb8-4b1c41bc095a.jpeg)](https://www.alphabetguides.com/tag/sleep/) ## How much protein do you need for muscle growth? Protein intake is fundamental for muscle growth; you can't build muscle without it. Protein provides the amino acid building blocks your muscle needs to grow. Protein intakes of 1.4–2.0 grams per kilogram of body mass daily are probably optimal for muscle growth when training. Distribution matters as well. Spreading protein across 3–6 meals throughout the day increases your chances of getting enough protein throughout the day.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/17909410/?ref=alphabetguides.com) ### Practical application: For a 75 kg person, aim for 104–150 grams of protein a day. Distribute it across 3–6 meals and snacks, targeting 20–50 grams every time you eat. Include protein sources at breakfast, lunch, dinner, and snacks (e.g., pre-bed, pre-workout, post-workout or between main meals). ## What protein do you need to build muscle? Protein quality (i.e., the amino acid profile and its digestibility) probably affects muscle growth as well. Animal proteins are generally “complete,” meaning they contain all essential amino acids in optimal ratios for muscle growth. [Plant proteins](https://www.alphabetguides.com/plant-based-protein/) often require combining different sources to achieve complete amino acid profiles. "Leucine" content of the protein is particularly important, as it acts as a key trigger for muscle growth. Animal proteins typically provide higher leucine content per serving compared to most plant proteins. ### Practical application: _This post is for subscribers only._ ### Minimalist Training: The Minimum Dose for Muscle Growth URL: https://www.alphabetguides.com/minimalist-muscle-growth/ Last updated: 2026-10-11T12:43:16.000Z summary - As few as two sets per muscle group per week can stimulate growth; 12 sets per week is generally optimal for most people. - Six to 12 reps at over 70% 1RM is the most time-efficient and evidence-backed load range for muscle growth. - Existing muscle can be maintained with as little as 1 set per muscle group per week during low-training periods. Despite the health benefits, [resistance training](https://www.alphabetguides.com/resistance-training-beginners/) is underused worldwide. Only around a quarter of adults in Western countries meet training recommendations (of 2+ sessions a week). Participation is low across all age groups, with older adults and those in poorer areas least likely to meet requirements. Low participation in resistance training is because most people dislike doing high-intensity exercise, have self-reported time constraints, and have a general lack of motivation to exercise. So we've decided to establish a “minimalist” approach to training that may improve participation by reducing intensity, frequency, or entry requirements. ## How little do you need to train to grow muscle? In addition to looking good, bigger muscles make everyday tasks easier and improve your health and quality of life. It also supports [healthy ageing](https://www.alphabetguides.com/andropause/). While athletes and those who're active seek "optimal gains", other people, with limited time or interest in resistance training, might be better off aiming for the minimal amount of training to get meaningful gains. In this article, we're not going to focus on strength, endurance, speed or athleticism — we're only focusing on size for now. Although many different training programmes stimulate muscle growth, there's no consensus on what (or how much) this is. ## Training volume: how many sets to build muscle? Training volume is the total work that your [muscle](https://www.alphabetguides.com/tag/muscle/) does. It can be measured as the number of sets multiplied by repetitions (sets × reps) or repetitions multiplied by load across sets (reps × load). Higher volumes are traditionally linked to greater growth, with research showing that multiple sets are better for growth than single sets. However, gains start to diminish beyond 3–6 sets and then plateau after 12 sets. Lower-volume resistance training of 3 or fewer sets per muscle group per week can stimulate growth, whereas as few as 12 sets may maximise it. Researchers have noted that there may be a volume-response for different muscles, with some muscles responding slightly better to higher volumes. For example, beginners show similar upper-body growth whether they complete single or multiple sets. Whereas lower body muscles seem to respond better to multiple sets. People who've been training for a while also seem to benefit more from multiple sets in both their upper and lower body muscles. Generally, greater gains are reported with multiple sets. In fact, a lot of so-called “single-set” training programmes are actually "single-set" multiple exercises that target the same muscle group. One set of three different variations of bicep curls is three sets, not one. There's some evidence to suggest that 1 set per week is less effective for muscle growth. Add this to the fact that lower-body muscles and trained people seem to respond better to multiple sets; it seems that the minimal number of sets per muscle per week is two. Scientists have reported a “dose-response” for volume, indicating that it is a strong driver of growth. 2 sets is the minimal amount, and 12 seems to be optimal, with (presumably) incremental gains between these two numbers. If you have easy access to your own gym, a work gym, or there's one on the way back from work, you can simply "micro-dose" your sets into quick sessions (say 15 minutes or less). Do your two sets for each muscle group after a quick warm-up set, then leave. Provided you get enough volume, the evidence seems to suggest you'll get similar results. Current resistance training guidelines generally recommend 2-4 sets per muscle group, 2-4 times a week, which gives you 4-12 sets per muscle group per week. Our minimalist approach is pretty similar. We just suggest that you do at least 2 sets per muscle group per week as a minimum. ## How often do you need to train to build muscle? Training frequency refers to the number of weekly sessions or times a muscle group is trained per week. It is closely linked to growth outcomes. When training volume is the same, frequency does not seem to matter.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/35291645/?ref=alphabetguides.com) In other words, 6 sets of bench press is no different to doing two lots of 3 sets in different sessions (just as long as you're pressing the same number of reps and weight in each set). However, training more often tends to lead to greater gains when volume is not controlled. Probably because you have [more rest](https://www.alphabetguides.com/rest-and-body-composition/) between sets, meaning that (in reality) you give more effort and lift more weight. Basically, splitting up your training probably means you're more likely to train better. It's not correct to say that more training means more growth. But more training likely leading to more volume, which leads to more growth, is a more accurate statement. If you're only doing 2 sets per muscle, it obviously makes no sense to break this into two separate sessions. However, if you want better results, you probably want to "split" working different muscle groups across different training days. General guidelines recommend 2-3 sessions a week. But we think that it is possible to achieve decent results from 1 session per week, provided you're able to complete 2 sets on all major muscle groups.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/28834797/?ref=alphabetguides.com) ## What weight and rep range builds muscle most efficiently? Training load is a controversial topic. Each percentage of your one-rep max corresponds to a repetition "range": “low” loads (less than 30% 1RM, more than 20 repetitions), “moderate” loads (30-70% 1RM, 12-20 repetitions), and “high” loads (more than 70% 1RM, fewer than 12 repetitions). Traditionally, moderate-high loads of approximately 80% 1RM for eight to 10 repetitions have been recommended to optimise growth. There is research to suggest that low/moderate loads can lead to comparable gains. However, the most robust evidence comes from higher loads2. You have to train harder with lower loads if you're going to get the same results as lifting higher loads.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/38970765/?ref=alphabetguides.com) So, while you can achieve similar results, higher loads are more [time-efficient](https://www.alphabetguides.com/cut-your-training-time/). They require fewer reps and less effort. However, lighter loads may work better for home gyms and home workouts. Lifting 6–12 reps at higher loads (over 70% 1RM) remains the most practical and best-evidenced range for maximising growth. But context matters. Your personal preference, experience, ability to train to failure and what equipment you have available can guide load selection. ## Contraction type: eccentric vs. concentric for muscle growth Eccentric contractions or negatives (where the weight is lowered) are often considered superior for muscle growth compared to concentric training (where the weight is lifted). This seems to be because you can lift more weight on the lowering part of the rep than the lifting part. Both types of contractions lead to muscle growth. But eccentric training seems to have better growth prospects as long as the weight is heavier. There are also "regional" differences between the two types of contractions. Eccentric training grows the muscle better near the joints. Concentric training is better at growing the middle of the muscle. So, unless you are targeting a specific section of your muscle, you're probably better off using both types of contraction. Which is what you probably do anyway (lift and lower the weight in each rep). Growth aside, eccentric training is generally better for increasing your strength, joint strength and rehab. Whereas concentric training seems better for developing speed. In the real world, most people are unlikely to have access to the specialist, expensive equipment needed for proper eccentric training. Most people are perfectly fine doing standard weightlifting exercises What the results from the eccentric exercise tell us is that lifting heavier loads to a high level of effort is probably better for growth. Secondly, it suggests that controlling the eccentric part of the movement with your muscle is very important — don't let gravity do the work for you. The lowering part of each rep should be slow and controlled, and if you have a good spotter, they can help you eccentrically overload the muscle on the last few reps of the set by helping you lift the weight into position. ## What rep duration is best for muscle growth? Training with slightly lighter loads (e.g., below 80% 1RM) allows you to slow the "tempo" or "velocity" of the rep. Reps that are 1-2 seconds are just as good (for growth) as ones that are 8 seconds long. However, very slow reps (over 10 seconds) appear **less** effective for growth.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/25601394/?ref=alphabetguides.com) General recommendations advise relatively slow reps (1-2 seconds lifting and 1-4 seconds lowering the weight, so 2-6 seconds total), which is fine. But for minimalist training, you can do your reps a bit quicker. It won't lead to better growth, but it is marginally more time-efficient — saving you a few minutes per session. So our recommendations for minimalist growth are to simply avoid slow repetitions. ## Are compound or isolation exercises better for muscle growth? Multijoint exercises recruit one or more large muscle groups across two or more joints. They require body stabilisation and engage muscles that are not used during single-joint movements. Single-joint exercises target smaller muscles around a single joint with greater precision. “Biarticular” muscles (i.e., muscles that cross two joints) may receive lower growth stimulus during multijoint exercises (like your hamstrings during a squat). Research has shown that the addition of single-joint “isolation” exercises doesn’t seem to be any better than multijoint exercises for muscle growth. Multijoint exercises engage more muscle mass per set and allow for shorter overall workouts. However, longer recovery periods may be needed. Therefore, multijoint exercises are recommended for minimalist training. But if time isn't a factor, single-joint "isolation" exercises are also fine for growth. If you're doing both types of exercise, there is no compelling evidence that performing one before the other is better for muscle growth. ## Can you build muscle with machine exercises? You can load your muscles with "free weights" (like barbells or dumbbells) or use machines, which guide you through the movement. Both types of resistance training are equally effective for muscle growth. There is no clear winner. Free weights are more versatile, cheaper and more accessible, as they can be transported, stored and fit all body shapes and sizes. However, you do need to take time to learn the free weight movements, so they are not great for beginners. That said, some free weights are easier to use than others. For example, barbell movements are usually easier than their dumbbell or kettlebell equivalent. But then again, dumbbells allow a freer range of movement and are quicker to use (no loading plates). The point we're making is that not all free weights are the same. Each has different pros and cons. Machines, in general, are easier to use. You don't have to waste energy to move or load them, and you can train to a high level of effort more safely (and don't require a spotter). So we're not giving any specific recommendations for minimalist training. Pick equipment you can move safely, efficiently, and confidently, and that you can easily access. ## Bilateral vs. unilateral training for muscle growth You can lift a weight ["unilaterally" (one side at a time)](https://www.alphabetguides.com/unilateral-exercise/), think one-arm or single-leg exercises. Or you can lift weights "bilaterally" with both arms or legs moving in the same way at the same time (e.g., bench press or squat). Bilateral exercises often allow you to lift heavier loads because they give you better stability, and there's more muscle mass involvement. For simple exercises, such as bicep curls or leg extensions, you may be able to lift more weight by only working one muscle at a time. However, both unilateral and bilateral training produce comparable gains in trained and untrained individuals. Bilateral exercises are obviously more time-efficient (half the required time). So, for our minimalist training approach, we recommend them if you're tight on time. However, unilateral exercises are fine as well for growth and may have the added benefit that they work your core a bit more effectively. ## Body weight training Body weight training can be performed anywhere and doesn't require any equipment, so it is a viable alternative to traditional weightlifting. But while it is possibly just as good for your general health, its ability to increase muscle mass is less compelling compared to weightlifting. Pull-ups, push-ups, squats and sit-ups are all effective exercises for muscle growth. However, once you reach a certain level, it becomes more challenging to continue growing (compared to weightlifting). So, increasing difficulty requires changing exercises (e.g., going from knee push-ups to standard push-ups). This means wasting time (from a growth perspective) in having to learn new exercises and then having to reach a sufficient level of strength in them to promote new growth. Bodyweight programmes can be effective for muscle growth, and they offer several other benefits. We just question whether they are the most efficient way to do it. We advise sticking to traditional weightlifting for efficiency. But bodyweight is fine if you don't have access to gym equipment ## Rest intervals ### Inter-set rest The rest interval between sets is typically perceived as a frustrating necessity for weightlifters who have limited training time. However, adequate rest between sets and between sessions is crucial for optimising growth. It allows your body to remove "metabolites" and replenish your muscles' energy stores. Not resting long enough can blunt your training performance, and thus your growth prospects. Common guidelines suggest resting anywhere between 30 seconds and 5 minutes between sets. However, rest periods in the mid-range (i.e., 1–3 minutes) may be optimal for growth and time-efficient.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/26605807/?ref=alphabetguides.com) There's evidence to suggest that experienced weightlifters, who're lifting heavier weights, might need longer rest (over 2 minutes). We recommend 2-3 minutes between sets. However, there are some training techniques that you can use to reduce the time of your workouts without compromising growth. ### Inter-session rest There is little research investigating the effect of the amount of rest between sessions on muscle growth. Recovery rates vary wildly between people and also depend on the intensity and type of resistance training you've done. Allowing at least 1 full day (48 hours) and up to 1 week of recovery per muscle is generally recommended. We agree. What you want to avoid is training while you're muscle are tired or sore. It is suboptimal and may be counterproductive for growth ## "Advanced" training techniques ### Supersets Superset training, also known as paired-sets or compound sets, involves performing two or more exercises in succession with minimal or no rest. Two different muscle groups are paired together (e.g., triceps and biceps), not two exercises of the same muscle (e.g., bench press and dumbbell flys). By reducing rest periods, supersets this increases “training density” of the session, allowing you to do more work in less time (but not compromising performance). There is evidence to suggest that supersetting different muscles is just as good as training each muscle individually. ### Drop sets Drop-set training reduces workout time by minimising the rest between sets. The method involves performing a traditional set, then reducing the load by 10-30%, and immediately performing another set, typically for one to five “drops”. Each "drop" is done to a high effort level (or near failure). Research suggests that similar gains in muscle growth occur between drop-sets and traditional resistance training sets. Again, it doesn't seem to promote growth any better; it just saves time without compromising growth. However, researchers have suggested that drop-sets aren't best suited to free-weight, complex or compound/multijoint lifts. ### Rest-pause sets The rest-pause method structures sets by including brief, preplanned rests (seconds) within a set. This can be single-repetitions and/or multiple-repetitions “clusters” interspaced with rest in a single “set”. The set can finish when failure is reached, or until a certain number of reps are completed. Unlike drop sets, rest-pause training maintains the same load. This means the same amount of work can be completed (i.e., reps, sets, load) within a short amount of time. So, like drop sets, this makes rest-pause techniques potentially a more time-efficient strategy for growth, without compromising it. There's actually some evidence suggesting that rest-pause is better for growth (and strength gains), as it encourages higher levels of effort.[\[6\]](https://pubmed.ncbi.nlm.nih.gov/28617715/?ref=alphabetguides.com) ## Blood flow restriction training [Blood flow restriction training](https://www.alphabetguides.com/blood-flow-restriction-training/) is a training technique that partially restricts blood flow to a working muscle using an external constricting device, such as a cuff or tourniquet, which provides mechanical compression to the vessels that supply blood to your muscles. Research suggests that blood flow restriction training can stimulate muscle growth when applied alongside low-load training. However, whether high- or low-load training, blood flow restriction does not appear to stimulate any additional muscle growth when compared to traditional resistance training. Lower pressures are generally perceived as more comfortable and less physically demanding, making them suitable for people with limited exercise tolerance. ## What time of the day should you train? _This post is for subscribers only._ ### The 3 Key Principles of Muscle Growth URL: https://www.alphabetguides.com/3-maxims-of-training-for-muscle-growth/ Last updated: 2026-10-11T12:42:31.000Z summary - Train at 60–80% of your one-rep max, finishing each set 1–3 reps short of failure. Training to complete failure is unnecessary. - Perform 10–20 working sets per muscle group per week; as few as 3 sets can produce measurable growth for beginners. - Gradually increase load, volume, or frequency over time — progressive overload is what sustains growth long-term. Muscle growth is driven by a small number of known principles. This article explains the three most important ones: intensity, volume, and progressive overload. They aren’t fancy concepts — they’ve been recognised since the time of the ancient Greeks. They are the bedrock that separates effective muscle-building programs from flashy gimmicks. Understand these three principles, and you're 90% of the way there; you’ll have a simple and effective framework for designing and performing training programmes. Simplicity is the aim of this article. But if you want some more detailed recommendations, see our [blueprint for beginners](https://www.alphabetguides.com/back-to-basics-a-checklist-for-muscle-growth/) and our [minimalist training guide](https://www.alphabetguides.com/minimalist-muscle-growth/). --- ## Maxim #1: Best Intensity for Muscle Growth Training “intensity” refers to how hard you’re working relative to your maximum capacity. It is usually measured as a percentage of your one-rep maximum (%1RM), how hard you're working, or how far you are away from failure. Don’t confuse “intensity” with screaming, grunting, or other gym theatrics. It’s a precise measurement that corresponds to the amount of mechanical tension in your [muscle](https://www.alphabetguides.com/tag/muscle/) (which is necessary for growth). In terms of your %1RM, studies show that muscle growth can occur at a broad range of %1RMs (e.g., 30-90% 1RM). However, the "moderate" 1RM range of 60–80% 1RM (equivalent to around 8–20 repetitions per set) seems to provide the most efficient and best-evidenced "load intensity".[\[1\]](https://pubmed.ncbi.nlm.nih.gov/33671664/?ref=alphabetguides.com) That said, even low-intensity loads (under 50% 1RM) can stimulate muscle growth equal to heavier loads — but only when performed at high levels of effort near failure. So, low "load intensity" but high "effort intensity". Without a high level of effort, training to (or near) failure, moderate to heavy loads (above 60% 1RM) are more effective and efficient for muscle growth. ### Measuring effort and intensity The Rating of Perceived Exertion (RPE) scale provides a practical way to gauge intensity, but it is completely dependent on your own perception of it. It’s usually measured on a scale of 1–10\. We’re all familiar with it and have probably been asked it before. However, the problem with the measure is that it is completely "subjective", meaning one person’s 6 is another person’s 8. A more focused (but still subjective) alternative is the “Repetitions in Reserve” (RIR) measure. This metric asks you to estimate how many more reps you *think* you could have completed before failure. An RIR of 2 means you stopped the set when you thought you could do two more reps. This makes RIR potentially more accurate than RPE for [weightlifting](https://www.alphabetguides.com/resistance-training-beginners/). “Velocity” maxes (%Vmax) are another metric. Even if you try to lift a weight as fast as possible, the speed at which you move will slow down as the weight gets heavier. This phenomenon is known as the “force-velocity” curve. High-level athletic trainers tend to use %Vmax as it can be monitored daily and even during a set. For maximising muscle growth, you should generally aim to finish most working sets with an RIR of 1–3\. This ensures that you have enough effort to stimulate growth while also minimising injury risk and prolonged recovery time. For muscle growth, we actually don't recommend training to complete failure and exhaustion, as it doesn't seem to make a difference.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/33497853/?ref=alphabetguides.com) ### Methods to measure intensity and effort - RIR: Repetitions in Reserve. How many more reps *could* you have done? - RPE: Rating of Perceived Exertion. How hard does it feel 1-10? - 1RM: One Repetition Maximum. How *much* weight can you lift? - Vmax: Maximum Velocity. How *fast* can you move the weight? - Pmax: Maximum Power Output. How *powerfully* can you move the weight? - MNR: Maximum number of reps. How many reps can you do? ### Common intensity mistakes **Training too light:** While low-intensity training (under 50% 1RM) can stimulate growth, your ‘working sets’ require high levels of effort. If you don't want to train this hard, lifting moderate to heavy loads is better for muscle building. **Training only heavy:** Constantly training above 80% 1RM primarily develops 1–5 RM strength. While incorporating heavy lifts can improve your strength, spending the majority of time in the 60–80% 1RM range is most efficient for growth. ### What intensity or effort should I train at? For muscle growth training, spending the majority of your time in the 60-80% 1RM range provides an efficient stimulus for growth. Although there is nothing wrong with venturing outside of it, either. Incorporating low-volume heavy lifting (> 85% 1RM) can improve 1RM strength. Lighter intensity sessions (under 50% 1RM) can be used to stimulate growth even when you don’t feel like lifting heavy weights and want to keep training momentum going. The concept of “autoregulation” (i.e., doing what you feel based on that day) is a good strategy if you are self-disciplined, motivated, and honest. However, most people tend to respond better to fixed targets. Are you a “Do this!” or “Do what you can” kind of person? Am I good at estimating my abilities? Do I respond better to execution or intention? There’s no need to get too introspective, but you do need to know yourself (or at least your coach does) for “autoregulated” training to work efficiently. ## Bottom Line Intensity is a strong signal for muscle growth, but it must be applied consistently. Too light fails to provide adequate stimulus for growth. But too heavy limits volume, increases fatigue and injury risk. The “sweet spot” is RPE 7–9, RIR 1–3 or 60–80% 1RM to drive growth. --- ## Maxim #2: Training Volume for Muscle Growth Training "volume" is the total amount of training you do, usually measured by the number of sets you do a week (per muscle group). However, for measurement purposes only, “effective sets” or “working sets count. These are the sets that are at your target loads and performed at high levels of effort. They are the ones which are done for growth (not to warm up). Both higher volumes tend to lead to increased muscle growth up to a point, after which returns diminish or *may* even regress. Balancing rest and recovery and training is complex and not just a simple formula. The most efficient training approach uses the minimum amount of exercise to stimulate the maximum amount of muscle growth. Twelve to 20 weekly sets per muscle group per week is optimal for muscle growth, with little additional benefit beyond this range. Measurable growth can occur with as few as 3 sets per week, but higher volumes generally produce superior results up to the 12–20 set threshold.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/35291645/?ref=alphabetguides.com)[\[4\]](https://pubmed.ncbi.nlm.nih.gov/33433148/?ref=alphabetguides.com) ### The volume landmarks Understanding volume "landmarks" helps you structure training: - **“Minimum effective volume”** is the smallest amount of training that produces measurable muscle growth. For most muscle groups, this falls around 2-3 sets a week per muscle group. - **“Most efficient volume”** is the highest volume you can recover from and sustain while still making progress. This varies significantly between individuals, but typically goes from 12-20 sets per muscle group per week. - **“Maximum effective volume”:** The absolute ceiling of volume you can handle before your performance starts to decline. However, you may get some immediate gains, but in the long run, it is [time-inefficient](https://www.alphabetguides.com/cut-your-training-time/) and unsustainable. The goal of training should be to: reach the minimum effective volume, aim for the most efficient volume, and stop training before you reach the maximum effective volume. ### Ways to split your training volume? This assumes that all other training variables remain the same. This usually doesn't happen in real life, as most of these variables are negatively correlated with each other. - Load per rep: Increase the set from 100 to 120 kg, and you'll increase the volume-load (or tonnage). - Number of reps per set: Do a drop set, cluster set or superset, and that will increase the number of reps per set and volume. - Number of sets per exercise: Do 3 sets instead of 2, and you'll increase volume. - Number of exercises per muscle: Doing an extra 2 sets of another exercise will increase the volume. - Number of muscles per exercise: Substituting [unilateral single-joint exercises](https://www.alphabetguides.com/unilateral-exercise/) (e.g., 1-arm dumbbell preacher curl) for multi-joint bilateral exercises (e.g., chin-ups) will increase volume. - Number of muscle groups per session: Exercising another muscle in the session increases volume. - Sessions per week: Increasing the number of times you train a week will increase volume. ### Individual and muscle group variations There are large individual responses to volume, where some people respond better to lower volumes, while others need higher volumes1. Different muscle groups also respond differently. Larger muscle groups (lats, quadriceps) respond better to higher volumes (12–20 set range). Whereas smaller muscle groups (biceps, triceps) may respond better to the lower end of the volume spectrum (3–12 set range). Novice lifters and older adults show particularly good responses to lower volumes (under 10 sets per muscle group per week). ### Volume myths debunked - **“More is always better”:** Growth rates increase linearly with volume, then level off after a certain point. Beyond 20 sets per muscle group per week, you get no further growth and increase injury risk and poor recovery. - **“Frequency matters”:** Splitting volume across 2+ sessions is probably easier than doing it all in one session. However, as long as the total volume, load and *performance* are the same, there's little extra benefit to splitting volume across multiple sessions. - **“Volume-load is king”:** While volume-load (sets × reps × weight) provides useful tracking metrics, volume (the number of sets) is generally a better long-term predictor of muscle growth outcomes than the total amount of weight moved. Too little volume will fail to maximise your growth potential. Too much volume exceeds recovery capacity, increases injury risk and impedes progress. Begin with research-backed ranges (e.g., 3-12 sets per muscle group per week), then adjust to your recovery, individual response, time availability, and personal preferences.[\[5\]](https://pubmed.ncbi.nlm.nih.gov/12618576/?ref=alphabetguides.com)[\[6\]](https://pubmed.ncbi.nlm.nih.gov/27102172/?ref=alphabetguides.com) --- ## Maxim #3: Progressive Overload to Build Muscle _This post is for subscribers only._ ### Mediterranean Diet for Health URL: https://www.alphabetguides.com/mediterranean-diet-fat-loss-health/ Last updated: 2026-09-14T12:25:52.000Z summary - The Mediterranean diet is linked to fat loss, better metabolic health, reduced cardiovascular disease risk, and longer life expectancy. - Its effectiveness is not just what you eat, but how you eat — whole foods, healthy fats, mindful meals, and physical activity work together. - Start small: add more vegetables to your meals, switch to olive oil, and eat fish twice a week. Small changes compound into meaningful results. The [Mediterranean diet](https://www.alphabetguides.com/tag/mediterraneandiet/) is a dietary pattern based on eating plants, olive oil, and minimally processed foods. This article examines its effectiveness for long-term health. Few dietary approaches have received as much sustained attention from researchers, clinicians, and the public as the [Mediterranean diet](https://www.alphabetguides.com/mediterranean-diet-guide/). But unlike short-term restrictive diets, it offers a proven dietary option that supports a healthy body and healthy body weight, without excessive hunger. It's not about counting calories or [eliminating entire food groups](https://www.alphabetguides.com/diet-framing/). Instead, it's a whole-systems approach; it's a lifestyle. People have followed it successfully for centuries ## Where did the Mediterranean diet come from? The Mediterranean diet didn't emerge from a laboratory or diet book; it evolved naturally from the traditional eating patterns of countries bordering the Mediterranean Sea (Greece, Italy, Spain, and southern France). This region's approach to food has been shaped by its geography, climate, and centuries of culinary tradition, which prioritised fresh, local ingredients and communal dining. The modern understanding of the Mediterranean diet began in the 1950s with the "Seven Countries Study" led by researcher Ancel Keys.[\[1\]](https://pubmed.ncbi.nlm.nih.gov/3776973/?ref=alphabetguides.com) Keys saw that compared to Westerners, Mediterraneans had significantly lower rates of heart disease and lived longer, healthier lives despite eating (relatively) high amounts of fat. This challenged the prevailing thought (at the time) that all [dietary fat](https://www.alphabetguides.com/eating-fat/) was bad for your health. What Keys and subsequent researchers discovered was that Mediterraneans weren't just eating differently; they were living differently. Meals were social events. Physical activity was naturally integrated into daily life. Food was viewed as nourishment and pleasure rather than fuel or restrictions. This "holistic" approach forms the foundation of why the Mediterranean diet is particularly effective for both fat loss and improving overall health. The cultural emphasis on fresh, [seasonal produce](https://www.alphabetguides.com/eat-the-seasons-the-seasonality-rule/), minimal processing, and cooking methods that preserve nutrients has created a dietary pattern that naturally supports good health. Unlike modern diets that are high in processed foods and added sugars, Mediterranean diet foods provide satiety with high nutrient density and low-calorie density. Although the “traditional Mediterranean diet” is strongly associated with lower rates of chronic disease, researchers have noted that this type of diet is gradually disappearing in the very regions where it was first started. Mediterranean regions adopting Western-style diets have increased consumption of [ultra-processed foods](https://www.alphabetguides.com/ultra-processed-food-an-introduction/), sugar, and junk food, which has contributed to increasing rates of obesity and metabolic disease across the Med. Some researchers now argue that the term “Mediterranean diet” increasingly refers to a historical ideal rather than the current average diet of populations in the region. Perhaps the “Roman Diet” is a more accurate name for it now? ## What can and cannot be eaten on a Mediterranean diet? At its core, the Mediterranean diet emphasises plant-based foods, healthy fats, lean proteins, and whole grains while limiting highly processed foods and excessive amounts of red meat and junk food. - **Plants (fruits and vegetables):** These form the foundation of every meal, filling half your plate with [colourful produce](https://www.alphabetguides.com/eat-the-rainbow-colour-matters/). Traditional Mediterranean-style diets are rich in fruits and vegetables, often exceeding the five servings per day. Plants give you fibre, antioxidants, and natural compounds that support your health. - **Extra virgin olive oil (EVOO)** is the primary source of fat. It is used for cooking, dressing salads, and flavouring dishes. It is rich in monounsaturated fats and antioxidants. It provides satiety while also supporting [heart health and metabolic health](https://www.alphabetguides.com/superfood-olive-oil/). - **Whole grains:** Unlike refined carbohydrates, Mediterranean whole grains like farro, bulgur wheat, and steel-cut oats provide energy and fibre that promote feelings of fullness and support your digestive health. - **Legumes:** Beans, lentils, and chickpeas combine protein and fibre in a low-calorie package. This versatile food group provide plant-based protein while keeping you satisfied between meals. - **Fish and seafood:** Consumed at least twice-weekly, [fatty fish](https://www.alphabetguides.com/superfood-oily-fish/) such as salmon, sardines, and mackerel contain omega-3 fatty acids that support cardiovascular and metabolic health, and fat loss. - **Poultry:** Lean protein sources like chicken and turkey provide essential amino acids for maintaining your muscle mass while you're losing fat, typically consumed in palm-sized portions. - **Eggs and dairy:** Used in moderation, these provide complete proteins and essential nutrients. Mediterraneans often favour fermented dairy like Greek yoghurt and aged cheeses. ### Foods used sparingly Red meat, processed foods, sweets, and other junk foods aren't eliminated but are treated as occasional rather than daily choices. This approach allows for flexibility while maintaining the diet's health benefits. The [Mediterranean diet](https://www.alphabetguides.com/mediterranean-diet-review/) naturally creates an environment that is conducive to fat loss: high-fibre foods are satiating, healthy fats can stabilise blood sugar, and nutrient-dense foods reduce cravings for processed foods. ## Is the Mediterranean diet scientifically sound? There are hundreds of independent studies demonstrating that the Mediterranean diet is effective for maintaining healthy body weight and preventing diseases.[\[2\]](https://pubmed.ncbi.nlm.nih.gov/18786971/?ref=alphabetguides.com) ### Weight loss and metabolic health Clinical trials have reported average weight losses of approximately 4–10 kg over 12 months among people that following Mediterranean diets. There were also particularly notable improvements in [waist circumference](https://www.alphabetguides.com/beyond-the-scale/), a key marker of dangerous visceral fat. One of the largest randomised trials on the Mediterranean diet followed thousands of people who followed it for nearly five years. Results showed that those who followed it had healthier body weights and lower chances of having a heart attack or stroke. The researchers also found that the diet improved diabetes risk factors, which also contribute to weight gain and fat storage. The high fibre and healthy fat content of the diet are cited as two key reasons for the diet's health benefits. ### Cardiovascular health Studies have also shown that the Mediterranean diet significantly improves cardiovascular health. The diet's content of "anti-inflammatory" foods appears to fight chronic low-grade inflammation, which is commonly seen in overweight people. Inflammation appears to increase your appetite, particularly for calorie-dense junk foods. So, by reducing inflammation, the Mediterranean diet is thought to help restore your normal (healthy) appetite. ### Longevity and cognitive health Perhaps most remarkably, the Mediterranean diet also improves longevity (or life expectancy) and brain health. A study which combined Mediterranean and [DASH diets](https://www.alphabetguides.com/dash-diet/) (referred to as the [MIND diet](https://www.alphabetguides.com/mind-diet/)) showed the chances of developing Alzheimer’s disease were halved.[\[3\]](https://pubmed.ncbi.nlm.nih.gov/25681666/?ref=alphabetguides.com) Another large study showed that people who followed a Mediterranean-style diet had a lower chance of dying and lived (on average) 2 years longer than those who didn't.[\[4\]](https://pubmed.ncbi.nlm.nih.gov/26848763/?ref=alphabetguides.com) --- ![Mediterranean diet food pyramid.](https://storage.ghost.io/c/69/dc/69dcec6d-c40d-40e8-823a-e4ec7bb45b10/content/images/2026/06/meddiet.png) --- ## Mediterranean diet: common mistakes Several misconceptions persist about the Mediterranean diet that can prevent people from experiencing its full benefits. ### “It's just olive oil and wine” While EVOO and moderate wine intake are components of the diet, they represent just a small part of its overall diversity. The real foundation of the diet is plants, whole grains, legumes, and lean proteins. ### “You can eat unlimited amounts of food” Although the Mediterranean diet doesn't require calorie counting, portion control still matters. Mediterranean people practise natural portion control by eating mindfully, socially, and being physically active. If you're specifically looking at losing weight, keep an eye on the calorie-dense foods like nuts, seeds, EVOO, wine and cheese. ### “It's too expensive” While EVOO and fresh fish can be costly, the diet's emphasis on seasonal produce, legumes, and whole grains can actually reduce costs. Limiting your intake of processed foods, red meat, and restaurant meals often offsets higher costs for ingredients like EVOO or fresh fish. ### “It's only for people of Mediterranean heritage” The Mediterranean diet's principles can be adapted to any culture and food preferences. In fact, some countries have adapted it for their own people. The key lies in emphasising whole foods, healthy fats, and plant-based ingredients rather than following specific recipes or traditional dishes. ## An example of a Mediterranean diet meal plan _This post is for subscribers only._
