Abstract
Background: Loss of control (LOC) eating in youth predicts excessive weight gain. However, few studies have measured the actual energy intake of children reporting LOC eating.Objective: The objective was to characterize the energy intake and macronutrient composition of “normal” and “binge” laboratory meals in nonoverweight and overweight boys and girls with LOC eating.Design: Children aged 8–17 y (n = 177) consumed 2 lunchtime meals ad libitum from a multi-item food array after being instructed to either binge eat (binge meal) or to eat normally (normal meal). Prior LOC eating was determined with a semistructured clinical interview.Results: Participants consumed more energy at the binge meal than at the normal meal (P = 0.001). Compared with youth with no LOC episodes (n = 127), those reporting LOC (n = 50) did not consume more energy at either meal. However, at both meals, youth with LOC consumed a greater percentage of calories from carbohydrates and a smaller percentage from protein than did those without LOC (P < 0.05). Children with LOC ate more snack and dessert-type foods and less meats and dairy (P < 0.05). LOC participants also reported greater increases in postmeal negative affect at both meals than did those without LOC (P ≤ 0.05). Secondary analyses restricted to overweight and obese girls found that those with LOC consumed more energy at the binge meal (P = 0.025).Conclusions: When presented with an array of foods, youth with LOC consumed more high-calorie snack and dessert-type foods than did those without LOC. Further research is required to determine whether habitual consumption of such foods may promote overweight. This trial was registered at clinicaltrials.gov as NCT00320177.
