Also, a new term I learned today is Keto-adapted. Apparently if you have been eating a VLC mostly meat diet for an extended period you becom Keto-adapted and your urinalysis would not indicate any ketone bodies because the body would be maintaining homeostatis, using ketones for fuel and not overproducing them. Apparently meat-only eating, keto-adapted humans will be utilizing ketones for fuel in their body (ie, be in ketosis medically speaking) but urinalysis will not show excess ketone bodies.
