After reading this title, you probably think it is the beginning of a joke, but it really is not. According to doctors the target amount of sleep you should get for optimal weightloss is 7.5 hours of sleep a night. This allows your body to complete the 5 REM cycles it needs to balance the gherlin and leptin hormones which tell you when to eat and stop eating. It does limit the amount of caffeine you consume---none after 2:30 pm and only one or two alcoholic drinks at dinner (which most people do not even approach). The studies have shown that by not changing anything else about your diet or exercise, a person can lose anywhere from 3 to 15 pounds in 10 weeks, just by changing their sleep schedule. Imagine how much that can increase by simply adding in exercise or dieting too. I think I'll start this one tonight.
