brown fat
Heat-generating adipose
Brown fat is a type of body tissue that generates heat by burning calories, unlike ordinary white fat which stores energy.
Concentrated in the neck and shoulders of infants, brown fat helps maintain body temperature.
Adults retain small amounts, and researchers study it for potential weight-loss applications: Scientists are investigating ways to activate brown fat.
