how much weight do you lose while sleeping
Fat Loss. Despite the weight loss, you don't shed a significant amount of fat as you sleep. A 155-pound person burns about 23 calories in 30 minutes while sleeping, according to Harvard Medical School, which translates to just 368 calories over eight hours. Shedding 1 pound of fat requires a deficit of 3,500 calories, so you can only lose about 1/10 pound of fat after a full night of sleep.
