Does any carb you have refill liver glycogen or ONLY fructose?
Also, goes liver glycogen ever get used to fuel muscles?
Can protein be broken down to refill liver glycogen?
Here is a wikipedia link…it might help.
I dont know all the answers to this however I do know that the liver takes priority over muscle glycogen.
For example if you wake up and the liver needs energy, the liver will be fueled before the muscles. I think the brain draws most of its energy from liver glycogen.
I could be totally wrong…double check with the wikipedia article.
