Increasing fat burning by reprogramming fat cells

White stores excess calories as fat that can be released for use in other organs during fasting. Mammals also have small amounts of brown , which primarily acts as an effective fat burner for the production of heat. Now researchers from the have uncovered the mechanism by which white from humans gets reprogrammed to become browner.
