Abstract: Objective To investigate the impact of preoperative eating behavior on weight loss after bariatric surgery, and provide relevant reference for predicting effects of bariatric surgery. Methods Of 85 obese patients undergoing laparoscopic sleeve gastrectomy, 44 cases were in restricted diet group, which was further divided into successful restricted diet subgroup (n=27 cases) and failing restricted diet subgroup (n=17 cases), and 41 cases in non-restricted diet group based on the Dutch Eating Behavior Questionnaire. Body weight, body mass index (BMI) and percentage excess weight loss (%EWL) were compared between groups and between subgroups at 6 and 12 months postoperatively. Results All patients completed laparoscopic sleeve gastrectomy successfully. Body weight and BMI of cases in restricted diet group were significantly higher than those in non-restricted diet group, while %EWL was significantly lower at 6 and 12 months postoperatively. In restricted diet group, body weight and BMI of cases in successful subgroup were significantly higher than those in failing subgroup, while %EWL was significantly lower. Conclusions Preoperative eating behavior had much impact on results of bariatric surgery, which could be used as reference for prediction of the results of bariatric surgery.
