The main supplier of glucose into the blood is the liver - either directly from its own glucose store (as glycogen, like muscle) or because it can turn fat and protein into glucose (called 'gluconeogenesis' - the new formation of glucose).

True, but as I noted, the muscles can also burn fats directly.

I don't believe that to be true but I would love to read your reference material supporting your argument. I personally have never read that, except some supplement claims but they also say you can turn fat into muscle which is pure BS.
