Bariatric surgery leads to significant weight loss but the results vary. Application of dietary principles like portion-controlled eating leads to greater weight loss and fewer complications.


To evaluate the improvement in weight loss outcomes by incorporating portion-controlled eating behavior in postbariatric patients.


All patients who underwent bariatric surgery from January 2012 to December 2013 were included in the study. Portion-controlled eating behavior was incorporated in the post-bariatric nutritional protocol. Their demographic, preoperative, and postoperative data were prospectively maintained on Microsoft Office Excel and analyzed statistically.


Three hundred and seventy-two (89.6%) underwent laparoscopic sleeve gastrectomy (LSG), while 43 (10.4%) underwent laparoscopic Roux-en-Y gastric bypass (RYGB). In the LSG group, lowest (nadir) BMI was 28.99 ± 5.6 kg/m2 and % Excess weight loss (EWL) was 87.3 ± 27.2%, achieved between 1 and 2 years. In the RYGB group, lowest (nadir) BMI was 27.5 ± 12.09 kg/m and % EWL was 94.32 ± 33.12%. Surgical failure (less than 50% EWL) were 10 (3.27%) in the LSG group and 1 (3%) in the RYGB group. There were no leaks reported in our study.


Our study highlights the importance of postoperative nutritional interventions like portion-controlled eating for successful bariatric outcome.
