How are ketones removed from the body?

Though it is the source of ketone bodies, the liver cannot use them for energy because it lacks the enzyme thiophorase (β-ketoacyl-CoA transferase). Acetone is taken up by the liver in low concentrations and undergoes detoxification through the methylglyoxal pathway which ends with lactate.

That is, higher ketones mean more fat burning.
