Food selection and intake of obese women with binge-eating disorder.

We studied food selection and intake of 19 women [body mass index (in kg/m2) > 30] [corrected], 10 of whom met proposed DSM-IV criteria for binge-eating disorder (BED). All subjects ate two multicourse meals in the laboratory, and were given tape-recorded instructions at each meal either to binge or eat in a normal fashion. Subjects with BED consumed significantly more energy than did subjects without BED at both the binge [12,400 vs 8440 kJ (2963 vs 2017 kcal), P < 0.005] and normal [9810 vs 6870 kJ (2343 vs 1640 kcal), P < 0.02] meals. During the binge meal subjects with BED consumed a greater percentage of energy as fat (38.9% vs 33.5%, P < 0.002) and a lesser percentage as protein (11.4% vs 15.4%, P < 0.01) than did subjects without BED. There were no differences in macronutrient composition of food choices between groups in the normal meal. Obese women who meet criteria for BED show differences in both intake and macronutrient composition of food choices from obese women who do not meet these criteria when asked to eat in a laboratory setting, supporting the validity of this new diagnosis.
