Description as written by the study sponsor.

Background/Objectives: Only 1% of the clinically eligible subjects receive surgical treatment for their obesity, thus other options should be investigated. In this study we aim to assess the effect of intensive-lifestyle-modification(ILM) with or without Liraglutide-3mg daily versus sleeve-gastrectomy(SG) on BMI at 1-year. Subjects/Methods: In this study performed in a University Hospital in Italy, non-diabetic patients eligible for bariatric-surgery are recruited from the weight loss clinic and have the option to choose within three possible weight-loss programs up to complete the allocation of 25 subjects in each arm matched by BMI and age. ILM consists in 600kcal very-low-calorie-diet(VLCD) for 1 month followed by 12kcal/kgbw high-protein, high-fat-diet for 11 months plus 30minutes brisk-walk daily and at least 3 hours aerobic-exercise weekly. SG patients have 1-month VLCD and free-diet thereafter. Patients are evaluated at baseline and at 1,3,6,9 and 12months.
