Values are presented as means ± SEM. Numbers in parenthesis in body weights are ‘n’ values; ‘n’ values for para and retro, as well as MFP and TF are the same as ‘n’ values in body weights in the same age group. Values with different letters in the same column indicate a significant difference. AL, ad libitum; ICR-R, ICR-restricted; ICR-RF, ICR-refed and CCR, chronic calorie restriction.
