Weekly average body mass of ad libitum-fed (AL, n = 28) and calorie-restricted (CR, n = 27) rats. Values for week 1 represent baseline body masses. In week 2, CR rats were given 90% of intake of AL rats. In week 3, CR rats were given 75% of intake of AL rats. In week 4 and thereafter, CR rats were given 60–65% of intake of AL rats. Body mass was significantly smaller for CR than AL rats (*P < 0.05) at week 3 and every subsequent week. To improve clarity, SE bars are not included; SE = 3.13–4.41 g for AL group and 2.46–3.84 g for CR group.
