Effect of caloric restriction on body weight (± SEM) of surviving DBA/2 and C57BL/6 mice as a function of age. Mice of each strain (n = 19−20) were maintained under the ab libitum (AL) or caloric restriction (CR) feeding regimen from 14 weeks until the rate of resting oxygen consumption was measured at 14−16 months of age. A 10% CR was initiated at 14 weeks (leftmost data point), which was increased in a stepwise fashion to 40% by 4 months of age. One mouse (a DBA/2 maintained on CR) died after 8.2 months.
