Bilateral accumbens sites from left and right brains of each rat are collapsed together here into a unilateral single map of accumbens for simplicity. Behavioral changes are expressed as within-subject percentage changes from vehicle microinjections at the same sites (vehicle, 100%). 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.Changes in hedonic “liking” ( A, B), aversive “disliking” ( C, D), and food intake ( E, F) caused by DAMGO microinjections. 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. 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). The hedonic rating of high-fat food stimuli decreased 6 weeks after RYGB and SG (all P ≤ 0.02). 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.ĪB - 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).

T1 - Bariatric surgery leads to short-term effects on sweet taste sensitivity and hedonic evaluation of fatty food stimuli 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.",
