 1990 and 2004, and I gained well over 100 pounds. OA is not a diet club. It's a 12-step program modeled after Alcoholics Anonymous. Members follow a food plan that's individualized for each person and rely on what they call a higher power, as well as meetings and talking with a sponsor. I have lost and maintained 120-pound weight loss. So right now I'm 5'6", and I weigh 140 pounds.
