On the energy fuel in voles during their starvation.

Starved voles derive energy predominantly from endogenous carbohydrates, unlike small laboratorial rodents which use free fatty acids as fuel during their fasting. This seems the reason why deep hypoglycemia is developed in fasting voles. The rate of gluconeogenesis in starved voles is rather high while oxidation of carbohydrates in that state is more rapid than their formation. Utilization of fat in fasted voles is relatively small. Voles can die after starvation still having a lot of fats in their bodies. Oxygen consumption in starved voles decreases to a small extent.
