Satiety and test meal intake among women with binge eating disorder

Abstract

Objective: The purpose of the study was to measure test meal consumption and the changes in hunger and fullness during a test meal in obese individuals with and without binge eating disorder (BED) and normal-weight controls.

Method: Twelve women with BED, 12 obese control participants, and 12 normal-weight control participants participated in two single-item test meal sessions. In one session participants were instructed to "binge," and the other eat a normal meal. Participants made ratings of hunger and fullness on visual analog scales after every 75-g increment of food.

Results: In comparison to obese or normal-weight controls, patients with BED consumed significantly more food to reach a similar level of fullness or hunger.

Conclusion: Individuals with BED consumed significantly more food and showed blunted changes in hunger and fullness during both the binge and nonbinge meals. These findings suggest that individuals with BED may have disturbances in satiety that in some ways resemble those described among individuals with bulimia nervosa.
