Brown Fat

The fat that burns to keep you warm.

Brown fat is metabolically active tissue that generates heat by burning energy. Regular cold exposure recruits and activates it — and the felt result is a body that warms itself more readily and runs a touch more efficiently. These pieces explore the science of brown fat and the cold that switches it on.
