claimCapsaicin was found to increase EE and fat oxidation, particularly at high doses, although results on the possible reduction in EI were mixed.In the present narrative review and updated meta-analysis, we evaluated whether culinary doses of RP can attenuate adaptive thermogenesis and decreased fullness during negative EB in humans.

claimOverall, long-term capsaicin consumption in free-living conditions did not provide statistically significant evidence for an EE increase but did significantly reduce RQ, suggesting sustained higher fat oxidation.

claimSubgroup analysis by EB showed that capsaicin significantly increased EE in controlled EB (SMD = 0.74; 95% CI, 0.25 to 1.24), while the increase in EE during controlled negative EB did not reach statistical significance (SMD = 0.90; 95% CI, –0.13 to 1.94) ().

claimRelatively higher protein diets, which reduce total EI by lowering fat and carbohydrate intake, have shown benefits such as sustained satiety, preserved FFM, and sustained EE that counteract adaptive thermogenesis.
