Bodyweight

Body weight and body composition are shaped by your biology, behaviour, environment, and lifestyle. This page focuses on sustainable evidence-based ways to lose weight, lose fat and improve your body composition. We really look at the science and the drivers behind it. Our content is for those seeking a clearer, more realistic understanding of managing your fat and muscle: "bodyweight" — one grounded in evidence, considers individual responses, and focuses on long-term health rather than short-term gains.

A healthy bodyweight is one that minimises your disease risk, supports physical function, and is sustainable through balanced eating and activity. BMI, body composition, waist circumference, metabolic health markers, and functional fitness are often better indicators of health than the number on the scale.

Healthy weight loss indicators include losing 0.5-1% of body weight per week, maintaining energy levels and workout performance, experiencing improved sleep and mood, and losing inches while preserving or building muscle mass.

No beverage specifically burns belly fat, but water is the best choice for supporting fat loss. Green tea and black coffee do have some fat burning properties, but the primary drinking strategy for fat loss is avoiding liquid calories from sugary beverages, excessive alcohol, and calorie-dense drinks.
