title: Studies in the ketosis of fasting.
abstract: A series of experiments was performed during the induction of starvation ketosis and in the acute reversal of the ketotic state. In contrast to the predictions of two widely held theories of ketogenesis, control of acetoacetate production by the liver appeared to be unrelated to changes in fatty acid mobilization from the periphery, fatty acid oxidation, fatty acid synthesis, or the acetyl coenzyme A concentration in the liver.Ketosis of fasting was shown to be reversible within 5 minutes by the injection of glucose or insulin. This effect was due to a prompt cessation of acetoacetate production by the liver. The possibility is raised that the ketosis of fasting is due to a direct activation of acetoacetate-synthesizing enzymes secondary to a starvation-induced depression of insulin secretion by the pancreas.
