The process is called "gluconeogenesis."
A separate question is whether there is any advantage or
disadvantage to using protein or carbs as a glucose source.
Offhand, I can't think of anything either way.
For those of us who are not getting much marrow or organ meats,
however, we probably need to rely on nuts and olives for adequate
levels of monounsaturated fats, and these are also carbohydrate
foods, of course. But that is only an indirect need for carbs...
