Changes in body weight (BW), energy intake (EI) and eating behavior (EB) during 12 wks of BW loss and 12 wks of BW loss maintenance were examined. Overweight/obese women (n=56; BMI: 29.8±2.9 kg/m 2 ; age: 35.5±7.2 y) were randomized to 1 of 2 diet plans. BW, EI and EB were measured at wks 0, 12 and 24. In this secondary data analysis, women were grouped by baseline EB as: high restraint/disinhibition (HR/HD); high restraint/low disinhibition (HR/LD); low restraint/high disinhibition (LR/HD); low restraint/disinhibition (LR/LD). Changes in BW, EI and EB were analyzed using repeated measures MANCOVA with pairwise comparisons to detect differences between groups and over time. There was significant BW (kg) loss ( p <.001), with no difference between diet groups ( p =.89). Over time, energy density (kcal/g) decreased ( p <.05), restraint increased ( p =.05), and there were interactions between EB group and time for energy (kcal, p <.05), BW ( p <.05), BMI ( p <.05) and restraint ( p <.05). There were differences between EB groups in energy [main effect p <.05, LR/HD>HR/HD p <.05], BW [main effect p <.01, LR/HD>LR/LD p =.01, LR/HD>HR/LD p <.05], BMI [main effect p <.01, LR/HD>LR/LD p <.01] and hunger [main effect p =.001, HR/HD>LR/LD p =.001, HR/HD>HR/LD p <.01]. The influence of EB on EI and BW should be considered during BW loss and BW loss maintenance. Funded by The Bell Institute of Health and Nutrition, General Mills Inc., Minneapolis, MN.
