I went to Overeaters Anonymous, which is based on Alcoholics Anonymous, using the Big Book, & everything, just substituting the word “food” and “eating” whenever possible for alcohol. Although now O.A. has its own book, but the basic 12 steps are the same & the basic premise is the same. It is a spiritual program. And I am not a spiritual person.
That said, I do have a close friend who is willing to deal with the “God” portion for me & believe for me. And there is a book, Agnostica, I think, & other books, just for atheists in programs like O.A. & A.A., but prayer is such an integral part of working the Program!
I’ve said this before & I’ll say it again — the absolute best part of the Program, it’s strength, at least in my mind, is the group. Sitting in the room, with other people who know EXACTLY how you feel because they’ve all been there (“Floor cake? Sure!” “Garbage cookie? Been there, done that!”) without judgement, just support & encouragment, hell, sometimes I go to O.A. meetings just to sit, knit & cry in the corner. And when I leave, I feel lighter of soul (which is the only supernatural thing I actually do believe exists).
