I was a terrible binger for years. I want to think of myself as an ex-binger now, but I really don't know if that is a thing and I always worry that I will start again. All I know is I haven't binged in the past maybe 3+? years. It's not like it happened over night either. Someone mentioned stalking the fridge/pantry with healthy food. This definitely helped me. Also.... I'd be driving along... and this still happens to this day... and I'd see fast food places or think of them... and really, really want fast food.....
And then I started telling myself: I can have it next time. It's poison. I can have my favorite x food, when get home (usually berries or a pita pizza or doctored down nachos- with low fat cheese and a serving of unsalted tortilla chips or something far less calories, fat and salt -than fast food). Sometimes I gave in but more often this began to work.
Or I'd tell myself: You don't want to gain back the weight you've lost. You will be hungry again, not very long after you eat that crap. Go home. Eat something delicious and healthy.... and I'd start mentally planning the meal that I would eat when I got home. It would be a healthy meal and I would tell myself how much better I will feel if I just get myself home and skip the junk.

Then, other times, when I was just feeling the urge to binge, at home, I would tell myself: Wait 10 min. Drink water. Go do something else. Take a nap. and ask myself: What am I really hungry for? (meaning emotionally... and if I could figure it out... I would deal with it, usually by meditation - though I call it relaxation and visualization). Sometime by crying. I probably should have been journaling. I bet that would have helped. Sometimes I didn't discover anything but I kept my mind occupied long enough for the binge urge to pass.

Sometimes.... I would just make a big bowl of popcorn and eat the whole thing. I still do this occasionally. I put a limited amount of butter on it and a bit of salt. I enjoy eating it and I tell myself that there is food value and much less sodium and fat in this bowl of popcorn than in eg. chips etc. So maybe I'm still a binger? Cuz I will eat that popcorn and usually... that would be my meal (popcorn for supper instead of whatever I had planned). But it doesn't usually cause me to retain water or gain weight, so I can live with being that kind of binger.

For sweet cravings I freeze fat free pudding. It is something I can eat slowly, for a reasonable amount of calories and by the time I finish, I feel satisfied and that ends the urge to binge. Or sometimes...I will have dark chocolate... but a measured, specific, reasonable amount and I will let it melt and take a long time to consume it. All the while, I'm telling myself how delicious it is, how much healthier it is, etc. than whatever much worse thing I would have eaten a whole bag of.
Then after all of this, I mentally praise myself. Good for me for not stopping for fast food. For eating a healthy meal. For making an intelligent, healthy choice. For not eating a bag of cookies (which I no longer have in my house and no longer crave or enjoy... believe it or not.... they're too sweet!). I tell myself I can do this.

For me, 3/4s of it is an argument in my head. If I can just talk myself into something reasonable, I can adjust my thinking after that. I understand that I won't die if I don't give in. But it's an ongoing struggle that I may never beat. I don't know.

Don't get me wrong. I still have a lot of weight to lose but at least, for the most part, I've stopped binging.
