Energy balance

Long-term capsaicin supplementation (135 mg/day) increases fat oxidation and restores resting energy expenditure after weight loss, but does not prevent weight regain in moderately overweight individuals.

Taking 135mg of capsaicin daily after losing weight will help your body burn fat more efficiently, but it will not stop you from regaining weight if you eat too much. It is a metabolic support tool, not a weight-loss guarantee.

GoodQualifiesHIGH confidence
These results indicate that capsaicin treatment caused sustained fat oxidation during weight maintenance compared with placebo. However, capsaicin treatment has no limiting effect on 3-month weight regain after modest weight loss.
