Improving weight loss by combination of two temporary antiobesity treatments
Background: It is generally accepted that the efficacy with an intragastric balloon decreases after the first 4 months of treatment. Aim of this study is to evaluate if the association of a very low-calorie ketogenic diet (VLCKD) can improve the results in terms of weight loss parameters and co-morbidities, as compared to usually prescribed low-calorie diet (LCD). Methods: For the present study (January 2016–June 2017), 80 patients (20 M/60 F, mean age 37.8 ± 6.1 years; excess weight 56 ± 10 kg; mean BMI 37.2 ± 3.8 kg/m2) underwent Orbera positioning. After 4 months, they were randomized into two groups according to the type of treatment: group A (Bioenterics intragastric balloon – Orbera + VLCKD) (n = 40), and group B (Orbera + LCD) (n = 40). Results: All patients completed the study with good adherence to diet therapy treatment allocation. After the 6-month treatment period, at time of Orbera removal, mean weight loss was 19 kg and 12 kg in groups A and B respectively (p
