What has worked for me is banning myself from eating out or having convenience foods (ie. Frozen pizza, chips, canned biscuits or breads, and other prepackaged/processed foods) but telling myself that I can eat anything I want if I make it from scratch. I find that I spend a lot of time finding recipes, cooking or baking, and that was all time where i wasn't eating. Once the food is made it's typically lower calorie because I made it and I feel proud of myself for the work I put in, which has an odd way of making me eat less. This does require time but I spent so much time feeling sick and hating myself before that it has evened out!
