Ketone, a source of energy in heart, brain. Ketones are produced in the body when fats, rather than glucose, are used to produce energy. This substance is an acid which can be harmful to the body if ketones are allowed to accumulate.
Ketones appear in the blood when there is not enough insulin in the body to change sugar into energy. When the body cannot use sugar, it uses fat and muscle stores for energy. The breakdown of the fat and muscle produces ketones. Ketones are an acid waste product that build up in the blood. This can happen when there is too little insulin in the body due to not taking enough insulin or illness. It can also happen when there is not enough food due to weight loss or skipping meals.
