Testing ketones are used for different reasons. The top uses are for various diets (ketogenic, paleo, atkins) and for managing type 1 diabetes. Ketone is a chemical produced when there is a shortage of insulin in the blood and the body breaks down body fat for energy. Ketones in the urine is a sign that your body is using fat for energy instead of using glucose because not enough insulin is available to use glucose for energy. In a nutritional diet, a person will have to achieve ketosis or nutritional ketosis which will effectively make the body burn fat for fuel instead of sugar from carbohydrates.
