This may seem impossible but you can actually lose weight by sleeping more. Experts say if you sleep eight hours a night it can promote weight loss. And this doesn't mean you have to be clinically overweight for this to work. The first thing you will want to do is get on a routine. Go to sleep and wake up at the same time every day. Start in the morning; write down what time you wake up and count back eight hours, this is when you should be going to bed. If it's the weekend and you are planning on staying out late just be sure to sleep in so you are still getting those eight hours.
