Overeaters Anonymous is a nonprofessional, self-supporting fellowship open to anyone who has a problematic relationship with food or eating, regardless of body size, diagnosis, or background.(Source) Like Alcoholics Anonymous (AA) and Narcotics Anonymous (NA), OA is based on a 12-step model that emphasizes honesty, accountability, and spiritual growth as a path to recovery from compulsive behaviors.

Founded in 1960, OA has grown into a global organization with in-person, online, and phone meetings in many languages.(Source) Members do not pay dues or fees; OA is supported by voluntary contributions. There are no weigh-ins, diets, or mandatory food plans. Instead, members focus on changing their behaviors, thoughts, and emotional patterns around food, body image, and control.

OA is not a substitute for medical or mental health care. Many people use OA alongside professional treatment for eating disorders, obesity, or other health conditions, working with physicians, therapists, and dietitians while also attending meetings for peer support.(Source)
