OA is not a diet club, and makes no claims for weight loss.  Each OA member should consult qualified professionals for their individual diet/nutrition plan, any medically approved plan of eating is acceptable. By admitting inability to control our compulsive overeating and abandoning the idea that all one needs to be able to eat normally  is "a little willpower," it becomes possible to abstain from overeating - one day at a time. OA offers members support in dealing with the physical and emotional symptoms of compulsive overeating.

Overeaters Anonymous has no dues or fees for membership. It is entirely self-supporting through contributions and sale of publications. Most groups "pass the basket" at meetings to cover expenses. OA does not solicit or accept outside contributions.
