Values are means ± SE. The baseline refers to the average of the last 3 days values before the restricted food access began for the ABA and the pair-fed groups.

*

Restricted food access increased mean daily activity compared to mean baseline values, t(13)=5.37, p<0.001.

**

ABA rats consumed significantly less food during restricted access than their baseline 24 h food intake, t(13)=9.97, p<0.0001.

†

At baseline running, the ABA rats weighed significantly less than both the pair-fed and naïve rats, F(2, 40)=5.67, p<0.01.

‡

Although consumed the same amount of food during restricted access, the ABA rats lost significantly more percentages of baseline weight than the pair-fed controls at the end of the restriction period, t(25)=7.36, p<0.0001.
