Background: The aim of this study was to propose dietetic guidelines for the nutritional management of weight regain in Roux-en-Y gastric bypass (RYGB) patients.
Methods: Thirty patients more than 2 years after RYGB surgery were followed up once every 15 days for at least 3 months. We collected from the medical records weight before surgery, excess weight, minimum weight reached 2 years after surgery, and percent of body fat before the operation.
