Chow and HF intake patterns in male (M), intact (F) and ovariectomized (OVX) female groups. (A - C) Both M and OVX SedHF rats (n=6/group) maintained high HF diet intake during 1st (day 0 - 15) and 2nd (day 30 - 38) exposure period. In F SedHF rats (n=7), HF intakes decreased and chow intakes increased over time during the two diet choice period. (D – F) Both M and OVX WRHF rats (n=5 and 6, respectively) avoided the HF diet during each exposure period. In contrast, F WRHF rats (n=5) gradually increased HF diet intake across days during each diet choice period. (G – I) During the 1st exposure period, F and OVX WR_HF rats (n=6/group) maintained high HF diet intake throughout the 11-day diet choice period. In contrast, M WR_HF rats (n=5) went from large consumption of the HF diet to equal intakes of the chow and the HF diet by the end of the diet choice period. During the 2nd exposure, the M and OVX WR_HF groups consumed more chow than HF diet. In contrast, F WR_HF rats consumed more HF than chow diet. Circle symbols represent SedHF groups, triangle symbols represent WRHF groups and diamond symbols represent WR_HF groups. *: p< 0.05 between chow and HF intakes; Note: Data from the last 2 days of the OVX WR_HF group was not included due to experimental error.
