Fasting-induced body temperature response in wildtype and CK−−/−− mice. In response to 12-hour fasting, an equal drop of 4–5°C in body temperature was evident late in the dark phase for (A) wildtype and (B) CK−−/−− mice. When food restriction was terminated the fall in body temperature in both groups rapidly normalized to initial values. Lines depicted are from individual animals.
