Socially engaging environments turn white fat to brown

In a neat study in mice, researchers found that mice that live in enriched environments with 15-20 other rats and lots of toys change their fat tissue from normal white fat to the calorie-burning brown fat. The researchers aren’t sure why – they say that maybe it’s a little bit of added stress from living with others, or else not being “lonely” that might be responsible. Fascinating and important to note that fat isn’t shaped just by what you eat.
