Plasma leptin (Fig. 2A) and NPY (Fig. 2B) concentrations after both types of dietary intervention: short term chow and fat diet for 2 weeks (STC/STF) and long term chow and fat diet (LTC/LTF). Results are expressed as mean ± SEM (n = 9 diet-induced obese rats, n = 9 control rats). Data were analysed by t-test: * p < 0.05, *** p < 0.0001.
