Binge eating disorder in a community‐based sample of successful and unsuccessful dieters

Abstract

This study examined binge eating and weight cycling in a community-based sample of successful (46 women, 44 men) and unsuccessful (29 women, 25 men) dieters. Successful dieters had lost at least 15% of body weight, kept the weight off for at least 1 year, and regained no more than 10 lb (average weight loss = 48 lb). Subjects completed a written questionnaire and were interviewed by phone several weeks later. Unsuccessful dieters were more obese when starting on a diet (average body mass index = 35.6 compared to 32.1) and were much more likely to have lost and regained 20 lb. Six-month prevalence of binge eating disorder (BED) was 19% for unsuccessful dieters and 6% for successful dieters; lifetime prevalence was 15% and 13%, respectively. Unsuccessful dieters were two to three times more likely to perceive a lack of control during an episode of overeating, to be disgusted with themselves for overeating, and to eat alone because they were embarrassed. Encouraging dieters to set realistic goals, identify potential relapse situations, and interpret lapses may help them succeed.
