Its Bega branch, which has been running for the last 25 years, is holding a public information afternoon for anyone who may have problems with either overeating or restricting their food intake. Long-time member and public relations officer Belinda, who did not use her last name as the organisation is anonymous, said the branch uses a 12-step model the same as in Alcoholics Anonymous and was for people who suffer from bulimia nervosa, anorexia nervosa or binge eating.
