为了探讨神经性暴食症的饮食模式特征，对19例未治疗的神经性暴食症、12例恢复期暴食症患者和21例自然环境下自然进食的正常对照进行了比较。受试者在日记中连续七天报告他们吃的或喝的每一样东西。进餐模式的相关性包括两组在进餐大小(和暴饮暴食的大小)、进餐频率、餐前和餐后间隔、剥夺比率、饱腹率、胃内容物以及膳食和暴食的组成方面的比较。结果表明，尽管报告的总摄入量是正常的，但只有33%的未经治疗的神经性暴食症受试者消耗的总卡路里没有立即被排出。被驱除的和未被驱散的暴饮暴食都是餐量的两倍，这与正常情况没有什么不同。假设未经治疗的暴食者的卡路里限制是暴饮暴食/排泄特异的，并被他们用作一种控制体重的形式。恢复组表现出对影响正常人进餐大小和餐间间隔的信号缺乏反应，包括进食的社会便利性受损。他们的饭量也更大，用餐频率也更高。据推测，康复的暴食症患者使用了其他尚未指明的食物摄入限制方法，导致了不正常的进食模式。
In order to examine the meal pattern characteristics associated with bulimia nervosa the meal patterns of 19 untreated bulimia nervosa, 12 recovered bulimics, and 21 normal controls spontaneously eating in their natural environments were compared. Subjects reported in a diary everything they either ate or drank for seven consecutive days. Meal pattern correlations included comparisons of the groups in regard to meal size (and binge size), meal frequency, premeal and postmeal intervals, deprivation ratios, satiety ratios, stomach contents, and composition of meals and binges. Resulted indicated that, although total reported intake was normal, only 33% of the total calories consumed by the untreated bulimia nervosa subjects were not followed immediately by purging. Both purged and unpurged binges were twice as large as the meal sizes which did not differ from normal. It is hypothesized that the caloric restriction of untreated bulimics is binge/purge specific, and is used by them as a form of weight control. The recovered group showed a lack of responsivity to the signals that influence meal size and intermeal intervals in normals including impaired social facilitation of eating. They also had larger meal sizes, and greater frequency of meals. It is theorized that recovered bulimics employ other, as yet unspecified means of food intake restriction resulting in abnormal feeding pattern.
