Awareness of addiction is a huge step. Geneen Roth has written a number of books about addictive eating that I have found helpful. Mindfulness and DBT training can also be helpful in overcoming compulsive over-eating and replacing negative thought processes. Some people find 12 step programs helpful. For many, the answer really is eliminating the trigger foods such as white flour or sugar. It's important to realize though that an over-dependence on sugar substitute never quiets the longing and desire for sugar though.
I don't think there is any "one size fits all" answer. I know that I come from a family with compulsive and addictive behaviors. I have never picked up cigarettes, drugs or alcohol but have definitely relied on food. For the first 25+ years it wasn't much of an issue because I could eat what I wanted and stayed close to a healthy weight (maybe 10 lbs heavy). By the time I finally got a handle on my compulsive over-eating, between my Hashimoto's which is difficult to control even with Synthroid, my metabolic syndrome and the pain that makes working out difficult, I know WLS is the only way to help me attain a healthy weight. If I hadn't wrapped my head around the food issue though, having the surgery wouldn't really help in the long run. I had my first WLS appointment Jan 2 and have lost 15 lbs since then. Such a struggle since my metabolism is so messed up.
Do I still have an occasional candy bar and Coke pre-surgery? Yes. But I can't remember the last time I had a 16 oz bag of fun size Snickers bar and devoured them in an evening. If you are already post-op and still obsessing about food, please find a program, therapist, behavioral lifestyle class - something to help set you free.
Best wishes,
