Plasma insulin, glucose, and amino acid concentrations and food consumption during feeding BCAA- restricted diets in rats. Rats were fed a control diet with 20% amino acid (20AA), a low-protein diet with 5% amino acid (5AA), or diets with reduced amount of Val, Leu, Ile, or three BCAAs (BCAA) for 8 h. Plasma insulin and glucose concentrations from 0 to 2 h after feeding are shown as AUC (a and b, respectively), food consumptions for 0–1, 1–2 h after feeding are shown as a cumulative bar chart (c), and plasma BCAA concentrations 30 min after feeding are also shown (d). Values are expressed as means ± S.E.M. (n = 5 in each group). Results of statistical analysis are given above the graphs (*P < 0.05; **P < 0.01 vs. 20AA)
