“…A lack of decrease in the fiber intake by patients with T2D remission was unexpected, facing the restrictive procedures enrolled in the RYGB technique. However, changes in food preference are reported in animals and humans after RYGB and seem to be associated with modifications in taste sensibility and, mainly, digestive motivation [48]. Our observations may have a practical effect on dietary orientation for patients after RYGB, particularly with regard to a higher fiber intake.…”

Gut microbiota composition is influenced by environmental factors and has been shown to impact body metabolism. Objective: To assess the gut microbiota profile before and after Roux-en-Y gastric bypass (RYGB) and the correlation with food intake and postoperative type 2 diabetes remission (T2Dr). Design: Gut microbiota profile from obese diabetic women was evaluated before (n = 25) and 3 (n = 20) and 12 months (n = 14) after RYGB, using MiSeq Illumina-based V4 bacterial 16S rRNA gene profiling. Data on food intake (7-day record) and T2Dr (American Diabetes Association (ADA) criteria) were recorded. Results: Preoperatively, the abundance of five bacteria genera differed between patients with (57%) and without T2Dr (p < 0.050). Preoperative gut bacteria genus signature was able to predict the T2Dr status with 0.94 accuracy ROC curve (receiver operating characteristic curve). Postoperatively (vs. preoperative), the relative abundance of some gut bacteria genera changed, the gut microbial richness increased, and the Firmicutes to Bacteroidetes ratio (rFB) decreased (p < 0.05) regardless of T2Dr. Richness levels was correlated with dietary profile pre and postoperatively, mainly displaying positive and inverse correlations with fiber and lipid intakes, respectively (p < 0.05). Conclusions: Gut microbiota profile was influenced by RYGB and correlated with diet and T2Dr preoperatively, suggesting the possibility to assess its composition to predict postoperative T2Dr.

“…Bariatric surgery seems to reverse these obesity-related alterations in taste perception (7)(8)(9)(10). However, controversy exists (11)(12)(13)(14)(15).…”

“…It is unknown whether changes in taste perception are a consequence of altered food intake and weight loss after surgery or whether physiological changes caused by the surgical procedure have weight‐loss‐independent effects . Proposed mechanisms related to the surgical procedure include alterations in gut hormone responses, including glucagon‐like peptide‐1 (GLP‐1) . GLP‐1 is expressed in mammalian taste buds and is present in saliva, and GLP‐1 receptors are found on intragemmal taste‐afferent nerve fibers , suggesting a role in modulating taste perception.…”

Objective The aim of this study was to investigate the effect of bariatric surgery on sweet taste sensitivity and the hedonic evaluation of sweet, savory, and fatty food stimuli as well as associations with weight loss and food preferences assessed at a buffet meal test. Methods The detection and recognition threshold for sweet taste and the hedonic rating of sweet, savory, and fatty food stimuli were assessed before and after a preoperative diet‐induced weight loss and 6 weeks, 6 months, and 18 months after Roux‐en‐Y gastric bypass (RYGB) and sleeve gastrectomy (SG) (n = 29). Results The detection threshold for sweet taste decreased after the diet‐induced weight loss and 6 weeks after RYGB (both P ≤ 0.03). The hedonic rating of high‐fat food stimuli decreased 6 weeks after RYGB and SG (all P ≤ 0.02). Changes in the hedonic rating of high‐fat food stimuli were associated with increased preferences for high‐fat foods at the buffet meal (P = 0.03) and tended to be associated with weight loss (P = 0.05). No changes were detected for sweet and savory food stimuli. Conclusions RYGB increased sweet taste sensitivity; however, this effect was already seen after the diet‐induced weight‐loss. RYGB and SG decreased the hedonic evaluation of high‐fat food stimuli, but this effect did not translate into decreased preferences for high‐fat food.

“…Obese individuals may have a stronger hedonic response to foods than non-obese individuals [15,16], making weight loss challenging. Decreased liking or preference for energy-dense foods may result from changes in chemosensory function, gut-related hormones mediating food aversions [17], neural activation in reward-related brain areas, motivation to consume, and hedonic hunger [16,18,19,20].…”

Associations between Weight Loss, Food Likes, Dietary Behaviors, and Chemosensory Function in Bariatric Surgery: A Case-Control Analysis in Women

et al. 2019

We tested the hypothesis that successful weight loss post-bariatric surgery would be associated with healthier chemosensory function, food likes, and dietary behaviors than either unsuccessful weight loss or pre-surgery morbid obesity. In a case-control design, pre-surgical women with morbid obesity (n = 49) were compared with those 1-year post-surgery (24 Roux-en-Y Bypass, 24 Sleeve Gastrectomy) and defined by excess or percent weight loss as successful/unsuccessful. For self-reported smell/taste perception, more post-surgery than pre-surgery reported improved/distorted perception, especially if weight loss successful. Measured taste function (perceived quinine and NaCl intensity) was lower among weight loss unsuccessful versus pre-surgery patients, yet a genetic variation in taste probe (propylthiouracil bitterness) matched expected frequencies without significant pre/post-surgery difference. Regarding survey-reported liking, higher diet quality was seen in the weight loss successful (independent of surgery type) versus pre-surgical patients, with differences driven by lower sweet and refined carbohydrate liking. The post versus pre-surgical patients had greater restraint but less hunger and disinhibition. Patients reporting both higher diet quality and lower hunger showed greater % weight loss, independent of surgery type. Thus, successful weight loss 1-year post-bariatric surgery was associated with improved or distorted chemosensation and patterns of liking associated with healthier diets, especially if coupled with less hunger.
