Fig. 1. Active GLP-1 and total PYY in response to a liquid test meal Fig. 1. Active GLP-1 and total PYY in response to a liquid test meal. Active GLP-1 and total PYY circulating concentrations over the course of the test (respectively, A and B) in obese subjects before (black circles, n = 9) and 6 wk after (open circles, n = 9) RYGBP and in obese subjects matched with the experimental group for the BMI attained 6 wk after surgery (open diamonds, n = 6). Data are expressed as mean (± sem). <sup>a</sup>, P < 0.05 and <sup>b</sup>, P < 0.01 values are indicated for comparison relative to baseline (Bonferroni).

Fig. 3. Hunger and satiety VAS scores in response to a liquid test meal. Bars represent the AUC of hunger and satiety VAS scores after meal ingestion (respectively, A and B) in obese subjects before (black bar, n = 9) and 6 wk after (open bar, n = 9) RYGBP. Data are expressed as mean (± sem). <sup>a</sup>, P = 0.05 and <sup>b</sup>, P < 0.05 values are indicated for comparison between the two study time points (Wilcoxon rank test).
