In a previous paper we1 have shown that in children after the cessation of a ketosis induced by a ketogenic diet, the carbohydrate metabolism does not return to normal at once but passes through a transitory stage. During this stage, there appears to be an excessive ability to utilize carbohydrates. This is shown by the occurrence of only a slight rise in the blood sugar curve in a dextrose tolerance test.
