If you want to lose weight, then you actually want more fat, not less. But you need the right kind: brown fat. This special type of fatty tissue burns calories, puts out heat like a furnace, and helps to keep you trim. White fat, on the other hand, stores extra calories and makes you, well, fat. Wouldn’t it be nice if we could instruct our bodies to make more brown fat, and less white fat? Well, NIH-funded researchers have just taken another step in that direction .
