Objective To investigate the perception of hunger and satiety and its association with nutrient intake in women who regain weight in the postoperative period after bariatric surgery. Methods Cross-sectional study of adult women divided into three groups: weight regain ( n  = 20), stable weight ( n  = 20) (both at least 24 months after Roux-en-Y gastric bypass surgery), and non-operated obesity ( n  = 20). A visual analogue scale measured hunger/satiety perception while fasting, immediately after finishing a test meal, and 180 min after finishing the test meal. The incremental area above or under the curve was calculated. Food intake was analyzed by 3 days of food recall and adjusted for intraindividual variation. To make between-group comparisons, Mann-Whitney, ANOVA, Kruskal-Wallis, and independent-samples T tests and Pearson’s correlation were used. Results There were no between-group differences in incremental areas of hunger/satiety, but protein intake was significantly lower among patients who regained weight compared with those who had stable body weight (0.99 ± 0.23 g/kg body weight vs. 1.17 ± 0.21 g/kg body weight, p  = 0.047). In the group that regained weight, satiety was correlated positively with usual dietary protein density ( r  = 0.541; p  = 0.017) and negatively with usual carbohydrate intake ( r  = − 0.663; p  = 0.002). Conclusion Women who regained weight presented similar perceptions of hunger/satiety to those of patients without weight regain and with non-operated obesity. In patients who regained weight postoperatively, satiety perception was correlated positively with usual dietary protein density and inversely with usual carbohydrate intake.
