Being a compulsive overeater is no different from being an alcoholic or drug addict. The only difference is that you can avoid drugs and alcohol completely and you have to have a relationship with food every day for the rest of your life. It's actually the hardest addiction to live with. If you were an alcoholic and someone said to you that you were required to have a single drink three to five times a day, but were not supposed to ever drink to excess, or a drug addict who was required to take just one pill severeal times a day every day, but you're not supposed to ever take more than that...no one would ever make it through rehab.
