Lose Sleep And You'll Lose Muscle Instead Of Fat

There's the school of folks who say forget about fat or protein or type of exercise. It's much simpler than that—a calorie is a calorie is a calorie, and if you burn more calories than you take in, you'll lose weight. Yeah, that's true, except when it's not. Here's an interesting little wrench in the works. In a recent study, scientists took two groups of people and put them both on reduced calorie diets. But then they told one group to sleep for 7-8 hours a night and the other group to sleep for five hours a night. Both groups lost weight. In fact, both groups lost the same amount of weight. But here's what's interesting—the sleep-deprived group lost a much greater proportion of lean muscle mass. Only 48% of the pounds they lost were fat pounds. For the group that slept enough, 80% of the pounds were fat pounds. So yeah, you'll lose weight either way if you're cutting calories, but if you sleep enough, you'll lose the fat you want to lose, not the muscle you don't.
