Ketone bodies are produced as soon as any fat (body fat or eaten fat)
is beeing used (burnt) at a high rate, with simultaneuous
gluconeogenesis (by lack of carbohydrate in the food or by fasting).

Ketones are a normal sign of starvation, and occurs even in Orang Utans
in times if food shortage. Urang Utans are fruit eaters with ingest
*very* few fat. But in shortage times, fat is used and therefore ketone
bodies produced.

Ketone bodies are also produced in times of carbohydrate starvation -
like some on the list use to aspire.
By supplying fat and forcing the body into gluconeugenesis by cutting out
carbs. But that is quite a different thing.

The ketone smell (of aceton, a ketone body) is often associated with poverty
- because it's a sign of starvation. Similarly cancer stations in hospitals
are said to smell like aceton (because it's a illness sign in this case).

If you don't *eat* fat, the ketones can tell you for shure, that body
fat is used up.

fine :-)
