Food Reward After Bariatric Surgery and Weight Loss Outcomes: An Exploratory Study
Open accessPublished version of a preprint
Abstract
Changes in food preferences after bariatric surgery may alter its effectiveness as a treatment for obesity. We aimed to compare food reward for a comprehensive variety of food categories between patients who received a sleeve gastrectomy (SG) or a Roux-en-Y gastric bypass (RYGB) and to explore whether food reward differs according to weight loss. In this cross-sectional exploratory study, food reward was assessed using the Leeds Food Preference Questionnaire (LFPQ). We assessed liking and wanting of eleven food categories. Comparisons were done regarding type of surgery and Total Weight Loss (TWL; based on tercile distribution). Fifty-six patients (30 SG and 26 RYGB) were included (women: 70%; age: 44.0 (11.1) y). Regarding the type of surgery, scores were not significantly different between SG and RYGB, except for ‘non-dairy products – without color’ explicit liking (p = 0.04). Regarding TWL outcomes, explicit liking, explicit wanting and implicit wanting, scores were significantly higher for Good responders than Low responders for ‘No meat – High fat’ (post-hoc corrected p-value: 0.04, 0.03 and 0.04, respectively). Together, our results failed to identify major differences in liking and wanting regarding the type of surgery and tended to indicate that higher weight loss might be related to a higher reward for high protein-content food. Rather to focus only on palatable foods, future studies should also consider a broader range of food items, including protein reward.

For both Roux-en-Y gastric bypass and sleeve gastrectomy, there is a decrease in preference for high fat and calorie-dense foods and an increase in healthy food intake following bariatric surgery.
“A recent study demonstrated that for both Roux-en-Y gastric bypass and sleeve gastrectomy, there is a decrease in preference for high fat and calorie-dense foods and an increase in healthy food intake following bariatric surgery (46).”
From Behavioral Interventions to Attenuate Driven Overeating and Weight Regain After Bariatric Surgery (2022) · cites this paper as [46]
The Introduction reports lower lipid intake and greater consumption of healthy foods after bariatric surgery; the Discussion reports prior studies finding reduced preference for fat and calorie-dense foods after both procedures. But this paper’s own study was cross-sectional and assessed food reward after surgery, not changes from before surgery or healthy food intake. It therefore reports evidence for the claim rather than demonstrating the full claim itself. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
