I don't binge/purge BUT in order to keep some level of control & stay at a healthy weight, I have no junk foods in my house. I live alone so it is easier. Anything I want takes time to prepare or is frozen & packaged in single servings. After all day working on my farm I am usually so exhausted it is all I can do to prepare one of those single serving meals. But I am usually hungry so definitely have to eat. Lol...keeping food frozen helps because when I am hungry I can only prepare enough frozen food for one meal.
Don't know if this helps....but it is how I control my healthy weight now
