Glycaemic response during oral glucose tolerance test (A), total area under the curve (AUC) (B), fasting insulin plasma levels (C) and homeostasis model assessment (HOMA) (D) of Wistar and Sprague-Dawley (SD) rats after 9 weeks of feeding either with standard (St) or high-fat (HF) diet. HOMA was calculated using the formula: fasting glucose (mg/dl) × fasting insulin (ng/ml)/405. Data are presented as mean ± SEM (n = 5–6 rats per group). *P < 0.05 vs respective St diet group and ^†P < 0.05 between HF diet groups.
