Often, in severe obesity, diet and physical activity are not enough to achieve a healthy BMI. Bariatric surgical approach, in particular laparoscopic adjustable gastric banding (LAGB), has encouraging results in terms of weight loss and resolution of obesity-related comorbidities. However, several months after LAGB, some patients are enable to lose weight anymore and don’t tolerate a further calibration because of its collateral effects (excessive sense of fullness, heartburn, regurgitation and vomiting).
The aim of this study is to identify the potential role of high protein-low carbohydrate ketogenic diet (KD) in managing weight loss in patients who underwent gastric banding and didn’t lose weight anymore.
50 patients underwent LAGB between January 2010 and December 2013. In twenty patients (GROUP A) we observed a stop in weight loss so we divided this patients into two groups. One group (group A1: 10 patients) continued to follow a LCD low calorie diet and underwent a further calibration; the other group (group A2: 10 patients) started to follow a KD for the next 8 weeks.
Both group resumed a significant weight loss, however group A1 patients reported collateral effects due to calibration and a higher Impact of Weight on Quality of Life – Lite (IWQOL-Lite) that correlates with a lower quality of life than patients following KD.
KD can improve the weight loss and quality of life in patients who underwent LAGB and failed at losing more weight allowing a weight loss comparable to that obtained with a further calibration and it is useful to avoid drastic calibrations and their collateral effects.
