I can't say what works for everyone, but what worked for me was having somebody at home take my keys and debit card from me so I had to ask for them which added a layer of thought/security to the impulse binging process (my binging is/was primarily fast food). That helped me to break the cycle in the beginning which was huge.

The other is like above, go shopping for food. Try not to fall into the all or nothing trap and deprive yourself but there's something to be said for more frequent, smaller trips to the store. I go to the store with two weeks in mind and count out the food to make sure it'll last me 2 weeks with a small treat here and there.

Don't mean to make it sound as easy as "just don't eat!" cause it's certainly not. But I think breaking the cycle is important because negative thoughts and feelings follow the negative action of binging... which leads to more binging. Once you resist one meal, one day, one week, you may find yourself addicted to that more healthy routine and be able to reel things back in. Good luck!

Edit: I put on 100 lbs between medications and binging, literally. I've lost about half of it.
