Blood glucose levels were measured after an oral glucose load (a). Blood glucose AUC in OGTT (b). Glucose stimulated insulin secretion (c) measured during OGTT (Δ-insulin = Insulin15min−Insulin 0min). HOMA IR (d) were calculated according to the formula: HOMA IR = Glucose (mmol/L) X Insulin (mU/L)/22.5. Blood glucose levels decrease after i.p. injection of insulin presented in % (e). Epididymal fat masses were measured at day 56 (f). n = 6–10. Data are presented as means ± SEM. *p < 0.05, **p < 0.01, ***p < 0.005, ****p < 0.0005 vs NC. White squares, NC; black squares, LC; white circles, NC+Ipra; black circles, LC+Ipra; white bars, NC; hatched white bars, LC; hatched grey bars, NC+Ipra; black bars LC+Ipra.
