I've gone to weekly WW meetings, OA, weighed in weekly with a diet doctor. Obviously none of that worked. Neither did my parents' promises of a new wardrobe if I got thin or my husband's worries about my weight. The night of my WW meeting was cheat night for me. I would starve myself before getting on their scale, or the doctor's and pig out later.
Bottom line---this forum works because I have to be accountable to ME, not a lecturer, not a doctor, not my family and friends.
