a couple years ago I was diagnosed with compusive eating disorder,whcih isnt to common and is pretty much I either binge and purge for long periods of time, to the expreme that it affects my health. I never own a scale until last august when I bought on simply to wiegh my lugage for an uncoming trip and have become obsessed with it, and enjoyed watching my wieght drop for 3 months. lately it seems as if eating is a game (as awful as that sounds) and I understand where you are coming from. i dont know about you, but i find that if I write down what I eat then I can look at it from a more resonable perspective and make changes (or atleast try) I know its not as easy as it looks but another alternative (besides therapy) could be to see a nutrisionist. You never know, it might help.
Good luck, and best wishes
