In brief: Fat breakdown

A common cause of ketone production (ketosis) is fatty acid breakdown.
When the body utilizes fats for energy, ketones result and some enter into the urine for excretion. A larger amount of ketones in the urine can occur in starvation, diabetes, and other conditions in which fat and fatty acid breakdown is occuring at a more substantial pace than in the normal metabolic state.
