Values are means ± SE. HFSED, HFD, sedentary; HFEX, HFD, exercised; LFSED, 10% fat diet (LFD), no sedentary; LFEX, LFD, exercise; n, no. of animals; BW, body weight; REA, epididymal fat pad weight/BW. Different letters represent significant between-group differences within time point based on ANOVA with post hoc Tukey's test.

Significant duration effect within group.
