The condition may be found in a diabetic patient who metabolizes fats instead of glucose for energy.

Ketonuria

Explanation:

Ketonuria, a name given to the presence of ketone bodies in the urine, occurs when the body cannot use glucose (sugar) to generate energy, either because of the lack of this nutrient in the bloodstream or metabolic problems, such as diabetes. In the absence of this fuel, the body will seek in the body fat the energy it needs. Ketones or ketone bodies are formed during the process of fat metabolization.

Ketone bodies in the urine may be a sign of decompensated diabetes, malnutrition, prolonged fasting, very strict diets, or any other situation that has caused the body to use fat as a source of energy, such as intense exercise.
