Definition: Ketones

Ketones

Glucose (a type of sugar) is the body's main energy source. But when the body can't use glucose for energy, it uses fat instead. When fats are broken down for energy, chemicals called ketones appear in the blood and urine. This can occur when not enough food has been eaten to provide glucose for energy, or it can occur in diabetes, when the body can't use glucose normally.
