Repeated measurements of (a) serum insulin (mU/l) and (b) plasma glucose (mmol/l) between lean insulin-sensitive (—, ●) and obese insulin-resistant (−−--, ○) subjects following ingestion of isoenergetic high carbohydrate (HC), high protein (HP), or high fat (HF) liquid mixed meals. Serum insulin iAUC_{0–360 min}: P = 0.023 for OIR vs. LIS; P < 0.001 for between test meals; and P < 0.001 for group × test meal. Plasma glucose iAUC_{0–360 min}: P = 0.673 for OIR vs. LIS; P < 0.001 for between test meals; and P = 0.157 for group × test meal
