What does brown fat do?

ANSWER

Brown fat, also called brown adipose tissue, helps maintain your body temperature when you get too cold. It's the same fat that bears use to stay warm when they hibernate.

Babies are born with a lot of brown fat behind their shoulder blades. Newborns can't shiver, which is one of the ways the body creates heat. Brown fat acts as a built-in heater. You lose most of it as you get older and form a shiver response to cold temperatures.
