Which metabolic outcome allows hibernating mammals to survive prolonged starvation?

💡 Explanation

Ketone body catabolism spares glucose; therefore, increased reliance on ketone bodies sustains cerebral function during hibernation because energy is derived from stored fat rather than glycogen depletion, rather than proteins, which would be fatal.
