Plasma glucose, glucose infusion rates, and insulin concentrations. Mean ± SEM concentrations of plasma glucose (A), glucose infusion rates (B), and serum insulin (smart insert in Fig. 1A) during hyperinsulinemic-euglycemic clamp experiments in groups of low weight (open cycles), normal weight (gray cycles), and obese (black cycles) men (n = 15 per group).
