Ex vivo lipolytic activity after nutritional intervention. Glycerol release rate (μg/mg of tissue/h) from periepididymal fat pads under basal or isoproterenol (Iso; 20 μM) stimulation were assessed in rats fed a standard chow (CT/CT, n = 7), high-sucrose diet (HS/HS, n = 6), initially fed a HS diet and then replaced by standard chow (HS/CT, n = 6) and fed a HS diet then replaced by high-protein diet (HS/HP, n = 6). The nutritional intervention started after 20 weeks post weaning and lasted for 12 weeks. Bars represent mean ± SEM, compared by one-way ANOVA (Newman Keuls). ^* represents p < 0.05, ^** represents p < 0.01, ^*** represents p < 0.001
