The concentrations of (A) blood glucose, (B) plasma triglycerides, (C) total cholesterol, (D) free fatty acids, (E) total ketone bodies, and (F) blood urea nitrogen in young and middle-aged mice (n = 6–8 per group) after 8 weeks of feeding. Data are presented as mean ± SEM and analyzed using two-way ANOVA followed by Tukey post-test to examine the effects of diet (A-F). * p < 0.05, ** p < 0.01, *** p < 0.001
