Snooze to Lose Fat
One of the biggest culprits slowing your muscle gains and fat losses may be lack of sleep. You’ve probably heard of cortisol, the stress hormone that causes your body to burn muscle tissue for energy, wreaks havoc with your health and leads to weight gain through various mechanisms, including carb binges. Researchers compared subjects getting six hours of sleep to those getting eight, and the six-hour group had 50 percent more cortisol in the bloodstream. If you want to get the best results from your workouts, be sure and get enough sleep to keep cortisol low.
