Hi, HB -
This is a forum for members of Overeaters Anonymous. If your problem is compulsive overeating, then it might be the right approach for you. It is not a diet plan - you can pick pretty much any eating plan that you want and use it in conjunction w/ OA. What OA does is help you to address the reason why you overeat. The approach is similar to Alcoholics Anonymous - we follow 12 steps. Here are a couple of links to check out for more information:
The Recovery Group
The Recovery Group is a group within OA that has a lot of info for people looking to find out about the program. Good luck, and if you have questions, post them here - I'll come back and answer.
