Energy balance
Acute ingestion of capsinoids (1–12 mg) does not significantly increase resting metabolic rate or fat oxidation in healthy human subjects within a 2-hour window.
Taking capsinoids (1-12 mg) will not increase your calorie burn or fat oxidation in the short term (2 hours). Do not rely on this supplement for immediate weight loss or metabolic boosting effects.
GoodRefutesHIGH confidence
Capsinoids provided in four doses did not affect metabolic rate and fuel partitioning in human subjects when measured 2 h after exposure.
Why this rating
Double-blind, placebo-controlled, crossover design with healthy subjects, though limited by short duration and low doses.
