Stunkard noted that the binge eating behavior was often associated with life stress self-condemnation, and that it had a personal or symbolic meaning to the individual.
Obese individuals with BED present a challenge for clinicians and nosologists alike, in part because their disorder is not limited to a single dimension. In fact, such individuals suffer from a constellation of difficulties that includes physiological, behavioral and psychological.
BED is common among individuals seeking treatment for obesity, and affects as many as 30% of these individuals, but is much less common in the general population. Available evidence indicates that BED occurs in 1-2% of the population, but in as many as 4-8% of obese individuals.
One model of etiology suggests that binge eating may lead to the onset or persistence of obesity. Another suggests that dieting in response to actual or perceived overweight may lead to the emergence of binge eating.
It is possible that binge eating contributes to the development or worsening of obesity. Some studies, although not all, suggest that presence of frequent binge eating is associated with more severe obesity. Binge eating is also associated with a history of weight cycling, although causality cannot be determined.
