What supplements have evidence for overweight management?

Fiber supplements (glucomannan, psyllium), green tea extract, and protein supplements (whey protein) have some clinical evidence for supporting modest weight reduction in overweight individuals when combined with calorie reduction. Effects are generally small, typically 1–3 kg over 8–12 weeks beyond placebo.

Can supplements alone address being overweight?

Supplements alone are unlikely to produce clinically meaningful weight loss. Most clinical trials showing positive results combined supplementation with reduced-calorie diets and increased physical activity. Supplements should be viewed as one potential component of a broader lifestyle modification approach, not a primary intervention.

When should someone who is overweight consult a doctor about supplements?

Consult a doctor if your BMI is 25 or above, especially if you have risk factors such as high blood pressure, abnormal cholesterol, or prediabetes. Medical guidance is important to screen for underlying causes, evaluate potential supplement-drug interactions, and develop a safe, comprehensive weight management strategy.
