This doesn't work for everyone~ But when I know that I have no self control over a certain kind of food, I don't even let myself have a little bit. For example; Pringles. I know that I won't just have one. So I don't have any.
If I were you, I'd get arid of all the "binge" foods in your home, and replace them with healthier alternatives. That way, if you really need to eat something, you can go for an item which is alot less damaging

Btw~ I love yourr display picture! Tokio Hotel are amazing!! <3
