Colonic temperatures of 17−18-month-old C57BL/6 (left panel) and DBA/2 mice (right panel) maintained under ad libitum (AL) or 40% caloric restriction (CR) regimens since 4 months of age. Colonic temperatures were sampled at 4-h intervals, over a 24-h period, while the mice were on a 12-h light:dark cycle (indicated by grey/white bars). The CR groups were fed at 2200 h to mimic the feeding cycle of the AL mice. Data are represented as the mean ± SEM (n = 12−13).
