About

Several studies report changes in food preferences in favor of low energy density foods after bariatric surgery and changes in scores of liking and desire to eat, as well as changes in hedonic evaluation certain foods. However, only one study was held in a more realistic condition of consumption by using real food, looking at some aspects of food preferences and giving contradictory results. We hypothesise that food preferences are different between obese people with and without a bariatric surgery. The main objective of this study is to compare the differences in food quality (proportion of total energy intake from foods with high energy density versus foods with low energy density), evaluated during a standardized and validated buffet between adult women with severe complicated or morbid obesity and women who have undergone bariatric surgery in the last 12 months.
