Meetings are gatherings of two or more compulsive eaters who come together to share their personal experiences and the strength and hope OA has given them. They are usually held once a week and run from an hour to an hour and a half. Though there are many types of meetings, fellowship with other compulsive eaters is the basis of them all.
According to the Traditions, bylaws and policies of OA, the only requirement for OA membership is the desire to stop eating compulsively. We ask each person attending to respect the meeting’s group conscience.
