Sleep Early! Posted at 9/19/2010 03:28:00 PM 0 comments (+) If you don't want to be eating an additional 560 calories everyday, then make sure you get enough sleep for the night. According to a study conducted, people who slept for only four hours will eat an additional 560 calories during the day as compared to those who had the recommended eight hours of sleep. That's why if you're watching your weight, don't just eat the right kind of foods and exercise, but make sure you also get at least eight hours of sleep at night. If you do all that, then there's no need to buy weight loss products.
