Modding your obsolete hunter/gather body to produce calorie burning brown instead of calorie storing white fat. Researchers at Joslin Diabetes Center, which last year led the way in demonstrating an active role for brown fat in adults, now have identified progenitor cells in mouse white fat tissue and skeletal muscle that can be transformed into brown fat cells. In some adults, the white fat cells that we all stockpile so readily are supplemented by a very different form of fat -- brown fat cells, which can burn energy rather than storing it.
