Special Issue Information

Dear Colleagues,

Obesity is a pressing global health concern, and bariatric surgery has emerged as an effective treatment option for individuals with severe obesity. Bariatric surgery induces significant weight loss and improves metabolic health by altering gastrointestinal anatomy and physiology; however, the post-surgical period requires meticulous nutritional management to ensure optimal outcomes and maintain a healthy body composition. This Special Issue aims to curate cutting-edge research and perspectives that shed light on the physiological intricacies influencing fatty tissue regulation, long-term body composition changes, and metabolic health after bariatric procedures. We welcome original research, reviews, meta-analyses, and perspectives that provide valuable insights into the role of gut microbiota, inflammation, type 2 diabetes mellitus, metabolic syndrome, and the evolution of obesity-associated comorbidities post-surgery. Our mission is to offer scholars in the field a comprehensive platform on which to share their contributions, advancing our collective understanding of bariatric surgery's potential impact.

Background: Progression diets after bariatric surgery (BS) are restricted in calories and protein, and they may induce a worsening of body composition. The aim of this study was to evaluate the effect of a modified diet with an oral nutritional supplement that is hyperproteic and normocaloric over the body composition. Methods: A two-arm ambispective observational cohort study was designed. Forty-four patients who underwent sleeve gastrectomy were included in the study. Thirty patients received a progression diet with a normocaloric, hyperproteic oral nutritional supplement during the first two weeks after surgery (820 kcal, 65.5 g protein). They were compared with a historical cohort of 14 patients treated with a standard progression diet (220 kcal, 11.5 g protein). Anthropometric and body composition (using electrical bioimpedanciometry) data were analyzed before BS and 1 month after the surgery. Results: The mean age was 47.35(10.22) years; 75% were women, and the average presurgical body mass index (BMI) was 45.98(6.13) kg/m2, with no differences between both arms of intervention. One month after surgery, no differences in the percentage of excess weight loss (%PEWL) were observed between patients in the high-protein-diet group (HP) and low-protein-diet group (LP) (HP: 21.86 (12.60)%; LP: 18.10 (13.49)%; p = 0.38). A lower loss of appendicular skeletal muscle mass index was observed in the HP (HP: −5.70 (8.79)%; LP: −10.54 (6.29)%; p < 0.05) and fat-free mass index (HP: 3.86 (8.50)%; LP:−9.44 (5.75)%; p = 0.03), while a higher loss of fat mass was observed in the HP (HP: −14.22 (10.09)%; LP: −5.26 (11.08)%; p < 0.01). Conclusions: In patients undergoing gastric sleeve surgery, the addition of a normocaloric, hyperproteic formula managed to slow down the loss of muscle mass and increase the loss of fat mass with no differences on total weight loss.
