Comparisons of energy intake and energy expenditure in obese women with and without binge eating disorder

Permanent URL:
The purpose of this study was to determine whether there are differences in energy intake or energy expenditure that distinguish obese women with and without binge eating disorder (BED). Seventeen obese women with BED and 17 obese controls completed random 24-hour dietary recall interviews, and had total daily energy expenditure (TDEE) assessed by the doubly labeled water technique with concurrent food log data collection. Participants received two baseline dual energy x-ray absorptiometry (DXA) scans and had basal metabolic rate (BMR) and thermic effect of food (TEF) measured using indirect calorimetry. Results indicated no between group differences in TDEE, BMR and TEF. As in our previous work, according to dietary recall data, the BED group had significantly higher caloric intake on days when they had binge eating episodes than on days when they did not (3255 vs. 2343 kilocalories (kcal)). There was no difference between BED non-binge day intake and control group intake (2233 vs. 2140 kcal). Similar results were found for food log data. Dietary recall data indicated a trend toward higher average daily intake in the BED group (2587 vs. 2140 kcal). Furthermore, when comparing TDEE to dietary recall and food log data, both groups displayed significant underreporting of caloric intake of similar magnitudes ranging 20-33%. Predicted energy requirements estimated via the Harris-Benedict equation underestimated measured TDEE by 23-24%. Our data suggest that increased energy intake reported by BED individuals is due to increased food consumption and not metabolic or under-reporting differences.
