  1. Fasting glucose, cholesterol, triglycerides (TG), free fatty acids (FFA), and leptin were measured in 3-, 7-, and 11-month-old males and females of both diets. The data are presented as mean ± SEM and were statistically analyzed by Mann-Whitney t test within each age and sex group (*HF vs St within the wt or Tau22 group, +Tau22 vs wt on the same diet). The age comparison was performed using mixed-effects analysis and Bonferroni’s post hoc test (#7 or 11 vs 3 months, $11 vs 7 months). Statistical significance for all measurements: *p < 0.05; **p < 0.01; ***p < 0.001
