Researchers have discovered the new hormone orexin, that activates calorie-burning brown fat and may help fight obesity.
Most of us would prefer to have less fat and more muscle. But there's one type of fat that researchers have been studying for it's fat-burning potential: brown fat. In fact, because brown fat is full of blood vessels and mitochondria, it's very good at converting calories into energy — thereby helping to prevent obesity. Fat that burns fat? Oh, the interesting irony!
In order to curb the growing obesity epidemic, researchers have been trying to learn more about brown fat. According to ScienceDaily, scientists used to believe that brown fat disappeared after infancy, but recent advances in imaging technology led to its rediscovery in adult humans. And now there's more information they've garnered: a hormone that activates brown fat in mice. Called orexin, the hormone is produced in the brain and an deficiency of orexin has been associated with obesity.
