Although I do have problems all year round, my main problem is winter. When my SAD kicks in, I don't want to exercise, and I crave comfort foods that are high in carbs (I don't tolerate carbs well, and they make me gain weight like crazy). So I wind up eating all sorts of vile things, usually in large amounts.
For the last couple of years, I've been trying to train myself to be fully aware of everything I eat and to make conscious decisions to eat or not eat anything at all. Right now, if I feel like eating, especially something I shouldn't, I try to do an internal Q&A: why do I want this food? am I hungry or just looking for comfort? what will happen if I eat it--what are the consequences? do I REALLY want to eat it?
Maintaining awareness does help. The self-interrogation helps. But we'll see what happens in another six weeks or so when I run into the blues again.
My main motivator right now is that I want to transition, but I don't want to go on T until I've gotten my weight down. I've completely connected transition with losing weight. And I really want to start T next year. So in my mind, if I want to transition, I have to become thinner. This kind of thinking has been enormously helpful with exercise, too. If I want to become the person I think I really am, I have to watch what I eat and get exercise six days a week.
I don't know whether you can find a hook like this. It works for me, so far. But if you stay aware of EVERYthing you eat, not just the bad stuff, then you might be less likely to binge. Have you consulted any sites about binge eating? I'll bet they have lots of tips.
