The greatest obstacle to losing weight is that you might struggle to simply stop eating. Compulsive eating can be difficult to get under control. Part of the reason is that people will often eat for emotional reasons. You may feel uncomfortable after you haven't eaten anything in awhile. A meal might be associated with a certain experience or you may feel sad and eat as a way to cope. By dealing with underlying causes of overeating, you may be able to get it under control.
