Background: Food addiction and binge eating are common among individuals with obesity. However, a paucity of studies prospectively examined the prevalence and implications of food addiction before and post-bariatric surgery. We aimed to examine the prevalence of food addiction and binge eating before and after sleeve gastrectomy (SG) and to assess their associations with behavioral and weight loss outcomes. Methods: We followed at 3 (M3), 6 (M6), and 12 (M12) months postoperative, 54 women who underwent SG. Data collected including anthropometrics, nutritional intake, food tolerance, and physical activity measures. The Yale Food Addiction Scale and the Binge Eating Scale were used to characterize food addiction and binge eating, respectively. Results: The mean baseline age and BMI were 32.1 ± 11.1 years and 44.9 ± 4.9 kg/m2, respectively. Pre-surgery, food addiction, and binge eating were identified in 40.7% and 48.1% of patients, respectively. The prevalence of food addiction decreased significantly up to M6, but increased to 29.3% at M12. The prevalence of binge eating decreased significantly through the follow-up up to 17.4% at M12. Those who met criteria for food addiction at M12 achieved significantly lower excess weight loss at M12 compared with those not meeting this criterion (P = 0.005). Food addiction scores at M12 negatively correlated with weekly physical activity (r = − 0.559; P < 0.001) and food tolerance scores (r = − 0.428; P = 0.005). Conclusions: The reduction in food addiction observed at M6 was not maintained at M12. Food addiction at M12 was associated with poorer weight loss, eating, and lifestyle behaviors. Clinical practice should focus on the psychological aspects associated with obesity.
