Have you ever been told you shouldn't eat close to bedtime if you are trying to lose weight? The theory is that your metabolism slows down when you are sleeping making it harder for you to lose weight than if you had eaten the same foods earlier. According to Donna L. Weihofen, MS, RD, health nutritionist at the University of Wisconsin Hospital and Clinics, "Calories count whether you eat them in the morning or at night." She goes on to say, "The problem with nighttime eaters is that they are usually eating far more calories than they think, and the calories are denser."
Note: If you are diabetic it is not a good idea to eat before going to bed.
