Work harder at not eating than not thinking about food or it can rebound. Trying to NOT think about something is similar to thinking about it. Change where your energy goes instead so you're fighting an action battle instead of an intellectual/thinking and emotional battle. I have a fiercely strong will, as I suspect you do, and know it can take me either way :-) Like arm wrestling with myself!

Milanist's ideas are great. However, I'm not an outdoor type, do more studying/school work/research, etc. I put non-food items in my refrigerator so if I "forget" and randomly open the door to fridge or cabinet, there's a new book or some other symbol of something I can do instead of eat. Maybe rearrange your cabinets so your "favorite" ones have pots and pans instead of food? Research healthful recipes (if you like to cook) and put ingredients on your shopping list (never shop without a list) and look forward to a new/special dish? I do that once a week at least, figure out something new to try, new recipe or ingredient or way to fix leftovers, etc. I'm trying to invent a "cookbook journal" writing about new things I'm doing and trying to figure out how better to "organize" my eating, mostly my shopping and preparing of food so it works for me and has more "purpose" and a place in my life instead of being outside of me, just a chore or something I have to do.

You might want to consider getting a physical and seeing a doctor or dietician just to get an "official" start weight and discussion going so it feels like you're in a "program" of your own making. I've been going to the doctor's recently for another problem but they do my weight, etc. each time and I've lost 9 pounds this summer which they remarked upon and which I'm more proud of than I thought I would be. I'm working hard to maintain the going down. Getting other people involved can help add a little involvement so one doesn't feel like one does battling one's own demons/head games. If you have a therapist, take 5-10 minutes of a session to talk about your weight with him/her, that might help too.
