Objective of Study: This study aims the comparison of weight and body composition changes in people who use and do not use protein in the first six months period after the bariatric surgery. Material and Method: This study was carried out on 144 patients who underwent bariatric surgery at a private foundation university between 10.01.2012 and 21.10.2014 and were followed up before and after the operation. The patients were separated into two groups those who use protein dust and who do not.The member quantity of two groups are equal and 72. Tanita Body Composition Analyzer TBF-300 was used to analyze the patients' body. Facts: The ages of the patients ranged from 18 to 68 years with an average of 37.87 ± 11.41 years, 63.3% using protein dust, and 36.7% not using protein dust although recommended. As a result of the study, the differences between the fat percentage ratios of the cases in both groups were statistically significant at postoperative 6th month controls (p<0.05). When the weight ratios of the cases were examined, no statistically significant difference was found between the two groups. When the muscle ratios of both groups are evaluated; The difference between the body muscle ratios of the post op 1st month controls was statistically significant (p <0.05) and the difference between the body muscle ratios of the two groups at the post op 6th month controls was statistically highly significant (P<0.01). Results: As a result, it has been observed that the body fat percentage decreases more than the body fat percentage according to the second group, which does not receive protein powder supplementation, in group 1 cases, which regularly take protein powder supplementation, and that body fat weight is less well preserved.

“…This stage involves a reduction in protein intake which affects fat but also lean mass leading to accelerated weight loss [ 47 ]. In the early PO period, patients submitted to gastric bypass surgery should start a liquid diet on the first day and maintain this diet for the first week following surgery [ 48 ]. Associated with this, patients have a surgical rest period with a restriction on moderate to high-intensity exercise [ 49 ]; pain is also a frequent issue following surgery.…”

BackgroundObesity represents a major public health problem and is the fifth leading risk factor for mortality. Morbid obesity is associated with chronic systemic inflammation which increases the risk of comorbidities. Bariatric surgery (BS) is considered an effective intervention for obese patients. However, BS is associated with dietary restriction, potentially limiting physical activity. Whole-body neuromuscular electrical stimulation (WBS) could represent an innovative option for the rehabilitation of BS patients, especially during the early postoperative phase when other conventional techniques are contraindicated. WBS is a safe and effective tool to combat sarcopenia and metabolic risk as well as increasing muscle mass, producing greater glucose uptake, and reducing the proinflammatory state. Therefore, the objective of this study is to evaluate the effects of WBS on body composition, functional capacity, muscle strength and endurance, insulin resistance, and pro- and anti-inflammatory circulating markers in obese patients undergoing BS.Methods/designThe present study is a randomized, double-blind, placebo-controlled, parallel groups clinical trial approved by the Ethics Committee of our Institution. Thirty-six volunteers (body mass index (BMI) > 35 kg/m2) between 18 and 45 years of age will be randomized to the WBS group (WBSG) or control (Sham) group (ShamG) after being submitted to BS. Preoperative assessments will include maximal and submaximal exercise testing, body composition, blood inflammatory markers, and quadriceps strength and endurance. The second day after discharge, body composition will be evaluated and a 6-min walk test (6MWT) will be performed. The WBS or Sham protocol will consist of 30 daily sessions for 6 consecutive weeks. Afterwards, the same assessments that were performed in the preoperative period will be repeated.DiscussionConsidering the important role of WBS in skeletal muscle conditioning and its value as an aid in exercise performance, the proposed study will investigate this technique as a tool to promote early rehabilitation in these patients, and as a strategy to enhance exercise capacity, weight loss, and peripheral muscle strength with positive systemic effects. The present study is still ongoing, and data will be published after its conclusion.Trial registrationREBEC, RBR-99qw5h.

“…113 However, enhanced absorption of amino acids does not compensate for the fact that many patients do not meet the dietary intake of 60 g of protein that is recommended for this population. 114,115 The evidence supporting this recommendation was rated as low; information on the impact of dietary protein on protein status during surgically induced weight loss is mostly observational, 116 and evidence from randomized clinical trials is extremely limited. 117 This is an important issue because sarcopenia is common after surgery, with patients losing 10% to 28% of lean mass.…”

The goal of the National Institutes of Health-funded American Society for Parenteral and Enteral Nutrition 2017 research workshop (RW) "Gastric Bypass: Role of the Gut" was to focus on the exciting research evaluating gut-derived signals in modulating outcomes after bariatric surgery. Although gastric bypass surgery has undoubted positive effects, the mechanistic basis of improved outcomes cannot be solely explained by caloric restriction. Emerging data suggest that bile acid metabolic pathways, luminal contents, energy balance, gut mucosal integrity, as well as the gut microbiota are significantly modulated after bariatric surgery and may be responsible for the variable outcomes, each of which was rigorously evaluated. The RW served as a timely and novel academic meeting that brought together clinicians and researchers across the scientific spectrum, fostering a unique venue for interdisciplinary collaboration among investigators. It promoted engaging discussion and evolution of new research hypotheses and ideas, driving the development of novel ameliorative, therapeutic, and nonsurgical interventions targeting obesity and its comorbidities. Importantly, a critical evaluation of the current knowledge regarding gut-modulated signaling after bariatric surgery, potential pitfalls, and lacunae were thoroughly addressed.

Effect of Protein Intake on the Protein Status and Lean Mass of Post-Bariatric Surgery Patients: a Systematic Review

Abstract: There is insufficient evidence of the effect of dietary protein on serum protein levels. Further studies are needed to better estimate the protein intake that supports a healthy nutritional status in this population.
