| | Ketones can also be excreted by the body when not used, therefore not being converted to bodyfat. | | | This process is termed "ketogenesis"ó which simply means the manufacture of ketones. | | | Coupled with MCTs ability to spare glycogen, the conversion of MCTs into ketones represents an additional source of energy for the exercising body. |

| | When severe, ketosis is known as ketoacidosis, because the body becomes over-acidified due to the acidity of two of the ketone bodies. | | | In all these cases the body is forced to use fat as an alternative energy source, and free fatty acids in the circulation are converted to ketone bodies in the liver. | | | Conditions leading to ketosis are fasting or starvation, a shortage of carbohydrate, or uncontrolled diabetes mellitus which results in the body's inability to utilize carbohydrate as an energy source. |
