Abstract
The marsupial Sminthopsis crassicaudata increases food intake following a fast. However, the role of metabolic fuel availability, in particular glucose, in the regulation of food intake in this animal is unknown. In this study, we have demonstrated that neither insulin-induced hypoglycaemia nor metabolic blockade of glucose utilisation with 2-deoxy-D-glucose effects food intake compared to saline-treated controls, suggesting that mechanisms other than glucose availability are important in the regulation of food intake in this marsupial. These data are discussed in the context of the role of glucoprivation in feeding in other mammals.
