Obesity, or more commonly known as overweight, is an abnormal or excessive fat accumulation condition that can be harmful to health. This causes metabolic disorders such as insulin resistance, which causes carbohydrate metabolism to be disrupted, so the energy the body needs is produced by fatty acid metabolism. The fatty acid metabolism process produces the ketone body that occurs in the urine or ketonuria.
