Abstract

Background Overeating as a pathogenetic hallmark of obesity may be promoted by an increase in hedonic hunger, ie, the drive to eat palatable foods in the absence of energy need. Gastric bypass surgery, which effectively reduces severe obesity, might also affect hedonic hunger.Objective The objective was to assess hedonic hunger in severely obese patients with and without a history of gastric bypass surgery.Design Severely obese patients who had not undergone gastric bypass surgery (n = 123), gastric bypass patients (n = 136), and nonobese control subjects (n = 110) were examined with the Power of Food Scale (PFS)--a questionnaire that reliably measures an individual's motivation to consume highly palatable foods.Results Compared with nonobese control subjects, severely obese patients achieved markedly higher aggregated PFS scores and subdomain scores related to generally available as well as physically present foods (all P < 0.001). On the aggregated score as well in those 2 subdomains, gastric bypass patients scored significantly lower than did non-gastric bypass obese patients (all P < 0.001) and did not differ significantly from the nonobese control group (P > 0.2). In contrast, in the PFS domain concerning food tasted, gastric bypass patients had significantly lower scores than did the nonobese control subjects (P = 0.04) and the severely obese patients (P = 0.008), both of whom did not differ significantly in this measure (P = 0.90).Conclusion In comparison with nonobese control subjects, severely obese patients display a marked increase in hedonic hunger that is not observed in patients who have undergone gastric bypass surgery, suggesting that the operation normalizes excessive appetite for palatable foods, which may be an important pathophysiologic feature of severe obesity.

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.
