The literature suggest that a wide range of problematic eating behaviours after bariatric surgery significantly influences weight results. However little is known on bariatric procedures comparisons. This study investigates the role of the two most performed worldwide bariatric surgeries on the presence of problematic eating behaviors, on weight outcomes also psychological variables, in a cross-sectional design. Additionally understand what variables directly influences weight loss. In total 126 Portuguese patients, who undergone sleeve gastrectomy (n = 78) or roux-en-y gastric bypass (n = 48) between one and three years follow-up, were assessed through a complete semi-structured clinical interview followed by five self-report questionnaires. Results shows the type of bariatric surgery performed does not directly affected problematic eating behaviors, weight or psychological variables. Both groups report a high percentage of problematic eating behaviors, 41% in the sleeve gastrectomy and 39.6% in roux-en-y gastric bypass in which increased weight regain was observed. Percentage of total weight loss is affected by age, time elapse since surgery, pre surgery body mass index, problematic eating behaviors, emotional eating and depression.
