True or False: Sleep is linked to weight loss	12/14/2009
TRUE     If you've tried dieting and exercise, but can't seem to shed those excess pounds, maybe you should try sleeping in.  A large study of almost 10,000 American adults aged 32-49 discovered that sleeping less than seven hours a night significantly increases your chances of being obese.  The same is true for children:  a study found that kids who were overweight slept less and had poorer quality sleep than normal-weight kids.    What does sleep have to do with weight control?  As it turns out, when you deprive yourself of sleep, your appetite-regulating hormones leptin and ghrelin get out of whack, causing you to feel hungry even when you've had plenty of calories.
