Since 1992, on the third Saturday in November, members of Overeaters Anonymous worldwide observe an International Day of Experiencing Abstinence (IDEA). The OA Fellowship created IDEA Day to encourage members and newcomers to abstain from compulsive overeating.
The WSBC, attended by delegates from around the world, meets annually each May to conduct the business of OA and to elect the 16-member Board of Trustees (BOT). The board acts on behalf of all members of the OA Fellowship. The World Service Office (WSO) works with the BOT to provide quality support and services to the entire OA Fellowship
Regions sponsor local conventions and assemblies. Regional assemblies also nominate trustee candidates to serve on OA’s Board of Trustees (BOT), whose members are elected at the World Service Business Conference (WSBC).
Two or more groups can form an intergroup (IG). The intergroup provides services to existing groups within its geographical area and spreads the OA message of recovery to those who still suffer.
A group consists of two or more people. Each group practices the Twelve Steps and Twelve Traditions of OA.
No member of a group is required to practice any actions to remain an OA member or to have a voice at a meeting.
