“…Moreover, Janmohammadi metaanalyzed the impact of bariatric surgery type on macronutrient intake: protein intake decreases post operatively in all surgery types, but this decrease did not differ significantly between surgery types [53]. Golzarand and colleagues corroborated this finding in a 6 month prospective study of 43 patients operated by sleeve gastrectomy or RYGB: postoperative protein intake decreased in both groups but protein intake, its proportion of energy out of the total energy and body composition did not change significantly between surgery type groups [54]. Therefore, protein intake is diminished in the initial phases after bariatric surgery but should not decrease too much since this affects the surgical outcome.…”

Dietary proteins have been used for years to treat obesity. Body weight loss is beneficial when it concerns fat mass, but loss of fat free massespecially muscle might be detrimental. This occurs because protein breakdown predominates over synthesis, thus administering anabolic dietary compounds like proteins might counter fat free mass loss while allowing for fat mass loss. Indeed, varying the quantity of proteins will decrease muscle anabolic response and increase hyperphagia in rodents fed a low protein diet; but it will favor lean mass maintenance and promote satiety, in certain age groups of humans fed a high protein diet. Beyond protein quantity, protein source is an important metabolic regulator: whey protein and plant based diets exercize favorable effects on the risk of developing obesity, body composition, metabolic parameters or fat free mass preservation of obese patients. Specific amino-acids like branched chain amino acids (BCAA), methionine, tryptophan and its metabolites, and glutamate can also positively influence parameters and complications of obesity especially in rodent models, with less studies translating this in humans. Tuning the quality and quantity of proteins or even specific amino-acids can thus be seen as a potential therapeutic intervention on the body composition, metabolic syndrome parameters and appetite regulation of obese patients. Since these effects vary across age groups and much of the data comes from murine models, long-term prospective studies modulating proteins and amino acids in the human diet are needed.

“…Of the three studies having tested the validity of the FR per se in their bariatric population, two studies [ 27 , 63 ] used indirect calorimetry as a reference and one study [ 121 ] used plasma concentrations biomarkers (vitamin A, D, E and C) as reference ( Table 3 ). Regarding the validity of the tools, Bobbioni-Harsh et al [ 27 ] found that the mean self-reported energy intake from their 3-day FR was 17.2% lower than energy requirement evaluated with indirect calorimetry pre-surgery.…”

Evaluation of Dietary Assessment Tools Used in Bariatric Population

Severe obesity is associated with major health issues and bariatric surgery is still the only treatment to offer significant and durable weight loss. Assessment of dietary intakes is an important component of the bariatric surgery process. Objective: To document the dietary assessment tools that have been used with patients targeted for bariatric surgery and patients who had bariatric surgery and explore the extent to which these tools have been validated. Methods: A literature search was conducted to identify studies that used a dietary assessment tool with patients targeted for bariatric surgery or who had bariatric surgery. Results: 108 studies were included. Among all studies included, 27 used a dietary assessment tool that had been validated either as part of the study per se (n = 11) or in a previous study (n = 16). Every tool validated per se in the cited studies was validated among a bariatric population, while none of the tools validated in previous studies were validated in this population. Conclusion: Few studies in bariatric populations used a dietary assessment tool that had been validated in this population. Additional studies are needed to develop valid and robust dietary assessment tools to improve the quality of nutritional studies among bariatric patients.

“…VSG has emerged as a popular and frequently performed surgical procedure for obesity treatment given its efficiency (several metabolic benefits even at ~ 20% mean reduction in the body weight) and allowance of revisional procedures ( 1 ). Furthermore, a significant reduction in the fat and fat-free mass has been reported following VSG ( 14 ). However, large variability exists in body weight reduction following VSG ( 15 ) and both preclinical and clinical studies report body weight regain following bariatric procedures, including VSG ( 16 – 18 ).…”

Objective Roux‐en‐Y gastric bypass surgery and vertical sleeve gastrectomy (VSG) are the most commonly performed bariatric procedures. Whereas studies report new‐onset alcohol misuse following Roux‐en‐Y gastric bypass, the impact of VSG on alcohol intake is less clear. Hedonic feeding, alcohol drinking, and hypothalamic obesity‐related gene expression following VSG were evaluated. Methods Male Long‐Evans rats underwent VSG or sham surgery. To evaluate hedonic feeding, rats received a high‐fat diet following behavioral satiation on chow. Alcohol (5%‐10% v/v) drinking was assessed in a two‐bottle choice paradigm. Finally, polymerase chain reaction array evaluated gene expression. Results VSG induced moderate but significant weight loss. Sham rats significantly escalated high‐fat diet intake following behavioral satiation, an effect significantly reduced in VSG rats. A moderate decrease in alcohol intake was observed in VSG rats at low (5%) alcohol concentration. However, overall, no significant between‐group differences were evident. Key hypothalamic orexigenic transcripts linked to stimulation of food and alcohol intake were significantly decreased in VSG rats. Conclusions VSG attenuated hedonic feeding without impacting alcohol drinking, an effect potentially mediated by alterations in genetic information flow within the hypothalamus. Importantly, these data highlight VSG as an effective bariatric procedure with a potentially reduced risk of developing alcohol use disorder.
