The hormone helps stave off weight gain because it's involved in the body's production of brown fat, which burns calories rather than storing them as white fat does, the study showed. Without orexin, mice are permanently programmed to be obese. With it, brown fat is activated and they burn more calories. People who are obese are thought to have less-active brown fat. Orexin is a hormone that is known to play a role in controlling appetite. In a paper published Tuesday, scientists have shown that orexin also activates brown fat to burn calories. Orexin, a hormone produced in the brain, activates calorie-burning brown fat in mice. Orexin deficiency is associated with obesity, suggesting that orexin supplementation could provide a new therapeutic approach for the treatment of obesity and other metabolic disorders.
