Interpretive Summary: It is unknown whether individuals with binge eating disorder (BED) actually consume more calories than individuals who are obese but not binge eaters. In order to assess the difference between in dietary intake between obese binge and non-binge eaters we evaluated dietary intake and energy needs in binge eaters and controls. Fifteen women fulfilling BED criteria and 17 controls participated in a multiple item over eating episode and completed a 24-hour dietary recall interview. BED participants consumed significantly more total kcal. Those with BED consumed significantly more calories per unit of body weight. Our findings confirm that those with BED consume significantly more than controls during a laboratory binge and controls are more accurate in recalling their intake 24 hours later.

Technical Abstract: The purpose was to: 1) Confirm that those with binge eating disorder (BED) consume significantly more kilocalories (kcal) than obese controls when instructed to overeat in the laboratory and 2) Compare dietary recall data with measured intake. Methods: Fifteen women fulfilling BED criteria and 17 controls participated in a multiple item over eating episode and completed a 24-hour dietary recall interview. Results: BED participants consumed significantly more total kcal according to both methodologies. The BED group self-reported 90% of the measured intake compared to 98% for the control group. Mean differences between the two methods indicated that on average both groups under-reported intake, however the mean difference between methods was significantly greater in the BED group. Those with BED consumed significantly more kcal per BMI. Discussion: Findings confirm that those with BED consume significantly more than controls during a laboratory binge and controls are more accurate in recalling their intake 24 hours later.
