My Q 3. "While we remain fasting and in ketosis, does this glycogen remain untouched, or does it continually get used and refilled"?
Your Q3 Answer: "yes again....replenished minimally."
I am confused as to what you are saying yes to... that the glycogen remains untouched or that it continually gets used and refilled. But the part where you say "replenished minimally" seems to imply that you are saying it remains mostly untouched, is used minimally and replenished to the full level soon after this happens?
What might be an example of when the body (in ketosis) would choose to use this glycogen instead of continuing to use the fat (primarily) and protein (secondarily) for fuel? Cardio above a certain level? Heavy Lifting?
What is the process by which ketosis is able to refill glycogen stores?
Adipose tissue which stores fat, is adipose tissue, itself, "protein"?... and is all tissue protein?
