Primarily it goes into energy, which gets used to convert pyruvate back into glucose, so the brain and muscle can leave aerobic metabolism on low. It can also make or interconvert most amino acids. The glycerol moiety can be made into glucose, but not the rest.

There's always a little bit of ketones about but Pritikin and Ornish should not
increase it over the basal level: no starvation and plenty of glucose.

Stryer's says the adipocytes just dump fatty acids into the blood, where they
complex with blood proteins. Other cells can take up the fatty acids
Normally, ketone bodies are just another way to ship fat energy around (I'm not sure why - they are more soluble). In Atkins-style ketosis, however, the body cannot use as much of the ketone bodies as it makes, so they pile up in the blood and eventually get lost through the kidneys.
