Background/Objectives: As only 1% of clinically eligible subjects choose to undergo surgical treatment for obesity, other options should be investigated. This study aimed to assess the effects of intensive lifestyle modification (ILM) with or without 3-mg liraglutide daily vs. sleeve gastrectomy (SG) on BMI after 1 year. Subjects/methods: In this study performed at an Italian university hospital, non-diabetic patients eligible for bariatric surgery were recruited from a weight-loss clinic and had the option to choose from three possible weight-loss programmes up to an allocation of 25 subjects in each arm matched by BMI and age. ILM consisted in 813. kcal of a very low-calorie diet (VLCD) for 1 month, followed by a diet of 12. kcal/kg body weight of high protein and high fat for 11 months plus 30. min of brisk walking daily and at least 3. h of aerobic exercise weekly. SG patients followed a VLCD for 1 month and a free diet thereafter. Patients were evaluated at baseline and at 1, 3, 6, 9 and 12 months. Results: A total of 75 patients were enrolled; retention was 100% in the SG and 85% in the two medical arms. SG reduced BMI by 32% (P <. 0.001 vs. medical arm), while ILM + liraglutide and ILM led to BMI reductions of 24% and 14%, respectively (P <. 0.001). More women allocated themselves to the ILM + liraglutide group. Weight loss was 43. kg with SG, 26. kg with ILM + liraglutide and 15. kg with ILM alone. Lean body mass reductions were -11.6. kg with SG, -6.3. kg with ILM and -8.3. kg with ILM + liraglutide. Prevalence of prediabetes was significantly lower with ILM + liraglutide, and insulin resistance was reduced by about 70% by both ILM + liraglutide and SG vs. 39% by ILM alone. Cardiometabolic risk factors were greatly reduced in all three groups. Discussion: At least in the short-term, liraglutide 3.0. mg once daily associated with drastic calorie-intake restriction and intensive physical activity promoted a 24% weight loss, which was almost two times greater than ILM alone and only about 25% less than with SG, while preserving lean body mass. Although this study was non-randomised, it was designed to explore the efficacy of medical treatments for obesity in everyday clinical practice.
