Sometimes I think that a food addiction is even worse than a drug addiction. With a drug addiction you have the luxury of being able to quit altogether. Ask anyone who quit smoking: most of them will say that they cannot just smoke the occasional cigarette. It’s all or nothing.
With food, that’s not an option. You have to come to terms with it somehow, and that in the presence of an advertisement industry that boasts that ‘you can’t eat just one’.
I second Jason’s comment and his book recommendations. I like Dr. Kessler’s book particularly well because it allowed me an insight into the mindset of over-eaters which I would not have had otherwise. Being somebody myself who really does not have an issue with food, it is not easy to understand what goes on in somebody’s mind who is powerless in the presence of food. This is well described in Dr. Kessler’s book.
