Fig. 3. Effects of three metabolic surgeries on plasma insulin and gut energy intake.

Fig. 3

a Schematic of the experimental process and procedures for several metabolic surgeries. b Time-dependent body weight changes of rats that underwent the indicated surgeries (n = 7). c Plasma fasting and glucose-stimulated insulin levels of rats that underwent the indicated surgeries (n = 8). d Food intake of rats that underwent different surgeries (n = 7). e Amounts of carbohydrates, fat, protein and total nutrients absorbed by rats that underwent the indicated surgeries, analyzed based on input (food) and output (feces) (n = 6). f Proportion of absorbed nutrients in rats that underwent the indicated surgeries (n = 6). Values are shown as the mean ± s.e.m. Significance was calculated using repeated-measures analysis (b) and one-way ANOVA with Tukey’s post hoc analysis (d) and two-way ANOVA with Tukey’s post hoc analysis (c, e). *P < 0.05 and **P < 0.01 compared with the pre-surgery body weight in b and the sham group in ce
