Objective: To examine weight change trajectories among overweight and obese patients with binge eating disorder (BED) versus without (NBO) during the year prior to seeking treatment. Methods: Participants were 97 (75 women, 22 men) overweight and obese patients recruited for the same weight-loss treatment in primary care; 26 (27%) met DSM-5 BED criteria. Participants were assessed with the Eating Disorder Examination and completed self-report questionnaires about their weight histories and the Beck Depression Inventory-II. Results: Participants' self-reported current weight and measured current weight were significantly correlated and did not statistically differ. Reported weight changes during the year prior to seeking treatment differed significantly by group: BED patients gained an average of 18.3. lb (8.2. kg) whereas NBO patients gained an average of 1.5. lb (0.7. kg). Among BED patients, but not NBO, weight change during the prior year was positively correlated with greater eating-disorder psychopathology, binge-eating frequency, frequency of overeating at lunch and dinner, and depression scores. For the overall group, BED status and binge-eating frequency each made independent significant contributions to predicting weight change in the past year. Conclusion: Findings suggest BED patients are gaining considerably more weight during the year prior to treatment than NBO patients. BED treatment may interrupt a steep weight gain trajectory and prevent further weight gain for BED patients suggesting need for early intervention. Primary care physicians should screen for BED when overweight and obese patients present with rapid weight gain.
