Sleep and Weight Gain: How It Really Works

Understanding what actually drives weight loss — and what only claims to — makes you a far better judge of any supplement.

Exercise and weight

Garcinia cambogia (HCA) is one of the weaker ingredients in the weight category. A Cochrane review found its effects small and statistically uncertain, and the FTC has acted against overstated HCA claims.

Chromium picolinate can help stabilise blood sugar, which may reduce cravings in people with blood-sugar swings, but for those without a deficiency, the benefit is usually small.

Green tea EGCG is one of the more studied weight ingredients, with modest evidence for boosting fat oxidation and metabolic rate by roughly 80–100 extra calories a day — helpful but not transformative.
