Results Whole-body energy expenditure (EE) after oral ingestion of capsinoids or placebo was measured for 2hr in 18 healthy male volunteers. Brown adipose tissue (BAT) activity was undetectable and high in 8 and 10 subjects, respectively. Resting EE of the BAT-positive group was 1,460 +/- 54 kcal/day (mean +/- SEM), not differing from that in the BAT-negative group (1,506 +/- 37 kcal/day). After oral ingestion of capsinoids, EE of the BAT-positive group increased in 0.5-1 hr by 3.6 +/- 0.6 kcal/hr, which was greater (P<0.01) than that of the BAT-negative group (0.4 +/- 0.9 kcal/hr). Placebo ingestion produced no significant change in both groups. Neither capsinoids nor placebo changed skin temperature in various regions including those close to BAT deposits.
