Energy balance

Brown adipose tissue (BAT) contributes to diet-induced thermogenesis (DIT) in humans, with individuals having higher BAT activity showing significantly higher postprandial energy expenditure compared to those with low BAT activity.

Your body burns more calories after eating if you have active brown fat. This is a natural physiological variation. You cannot directly 'take' this, but maintaining a healthy weight and potentially exposing yourself to mild cold may help maintain BAT activity.

GoodSupportsHIGH confidence
EE after meals was significantly higher in the high BAT group (9.7% of the total energy intake) than in the low BAT group (6.5%)... All these results indicate that BAT contributes to DIT, at least in part, in humans.

Why this rating

The paper cites human calorimetry studies showing significant differences in EE between high and low BAT groups.
