Abstract
The effect of vertical sleeve gastrectomy (VSG) on food preference has not been examined in humans, but VSG decreases preference for fat and calorically dense foods in rodents. A validated Food Preference Questionnaire (FPQ) assessed food preference changes before and 6 weeks after VSG in humans. The FPQ was completed before and 43 ± 19 days (Mean ± SD) after VSG. Fifteen subjects (14 females) completed the study. Hedonic ratings decreased for foods high in fat and sugar (p = 0.002) and high in fat and complex carbohydrate (p = 0.007). Fat preference (p = 0.048) decreased, VSG reduced preference for calorically dense foods high in fat, sugar, and complex carbohydrate, and these changes may contribute to the weight loss with VSG.
