Figure 2: (a) Mean (±SEM) serum insulin concentration in 8 healthy subjects after ingestion of water only (open circles), 25 g glucose (closed circles), leucine + phenylalanine at 1 mmol/kg fat-free mass each (open triangles), or 25 g glucose with leucine + phenylalanine at 1 mmol/kg fat-free mass each (closed triangles). Insert left—previous data with leucine alone [2]. Insert right—previous data with phenylalanine alone [3]. (b) Net-integrated AUC using the fasting values as baseline. Bars with different letters indicate that values are significantly different ( ).
