ResumoThe biochemical and physiological indices were monitored in 44 subjects after 4-week capsinoids (capsaicin analogues with low pungency) intake. The subjects were randomly assigned to 3 groups: CSNs3 (3 mg/kg of capsinoids), CSNs10 (10 mg/kg of capsinoids) and the control (placebo). Measurements were performed in the morning on overnight-fasted subjects. The oxygen consumption (VO(2)), resting energy expenditure (REE) and fat oxidation increased slightly compared to pre-administration values without any adverse effects, although the increase was not significant. The increase in fat oxidation was positively and significantly correlated with the body mass index (BMI). A meta-analysis was therefore conducted on a subgroup consisting of subjects with BMI >or= 25 (n=28). As a result, not only VO(2) increased significantly (p<0.05) in the CSNs10 group, but also REE in the CSNs10 group and fat oxidation in the CSNs3 and CSNs10 groups tended to increase (p<0.1). Consequently, a capsinoids intake would be able to enhance the energy expenditure and fat burning in humans, particularly those with high BMI.
