Eating behavior of bulimics, self-identified binge eaters, and non-eating-disordered individuals: what differentiates these populations?

This article reviews and critiques the eating behavior literature comparing the binge and non-binge-eating episodes of three populations of normal-weight women: bulimics, self-identified binge eaters, and non-eating-disordered women. The specific behaviors evaluated are number of calories consumed during different types of eating episodes, frequency of binge eating, number of eating episodes, rate of food consumption, the macronutrient composition of the food ingested, and context and duration of eating. Differences in these populations' eating behavior are analyzed in terms of their theoretical contribution. It is concluded that differences in the observed behavior of these groups are consistent with restraint theory, purge opportunity, and the forbidden foods hypothesis. Conversely, results do not support carbohydrate craving theory or a deficit in the satiety mechanisms of bulimics. Suggestions for future research are presented.
