Default How To Lower Cholesterol on Low-Carb Diet?

And you were answering:
| When we eat excess protein, how is it stored?
| I imagine some of it converted to glycogen and glucose by the liver.
| Some enters cell to be burned.
| Does the excess mostly stay in the blood?
| How would we even know we have excess protein?
| Is there a common blood measurement for this?
The test is for ketones in the blood. This, IIRC, can be OK, but it
might also be indicative of other problems.

Which gave me the impression that you were saying that ketones measured the
protein in the blood as the prior poster was asking for a test for excess
protein.
