Chow and HS intake patterns in male (M) and female (F) groups (n=6/group). Diet choice and wheel running occurred during between day 0 and 6. (A) Male SedHS rats preferred the HS diet throughout the 6 days diet choice period. (B) Female SedHS rats preferred the HS diet on days 1-4 but not on days 5-6. (C) Male WRHS rats sampled the HS diet initially and then completely avoided the HS diet for the rest of the diet preference period. (D) Female WRHS rats sampled the HS diet, completely avoided it and then gradually increased intake to equal amount with the chow diet by the 6th day of diet choice. *: chow vs. HF, p< 0.05; #: vs. day 0 intake, p<0.05
