Workouts Pump Up Helpful Hormone

Working out may stimulate the production of brown fat, a type of fat that burns calories instead of storing them. Previously, researchers discovered that a hormone, irisin, helps convert white fat—the type that stores calories—to brown fat. The question then was: How can we encourage the body to produce more irisin? To see if exercise might boost irisin levels, researchers took blood samples of 10 healthy volunteers before and after an hour of cycling. Irisin levels increased after the workout, suggesting that physical activity may persuade the body to make more brown fat.
