Ketosis /kᵻˈtoʊsᵻs/ is a metabolic state in which most of the body's energy supply comes from ketone bodies in the blood, in contrast to a state of glycolysis in which blood glucose provides most of the energy. Ketosis is similar to a condition called Ketoacidosis, in that both cause a side effect known to laypeople as acetone breath.
