Can someone provide ANY photographical evidence of a physique "going flat" or "spilling over" due to glycogen.
I would like to see a before and and an after. I think neither exist and it is not logical at all to think that they do exist.
Due to the body's ability to hold no more than around 2,000 kcal of glycogen, marathon runners commonly experience a phenomenon referred to as "hitting the wall" around the 20 mile (32 km) point of a marathon. (Approximately 100 kcal are utilized per mile, depending on the size of the runner and the race course.) When experiencing glycogen debt, runners often experience fatigue.
Only the glycogen stored in the liver can be made accessible to other organs, and these hepatocytes have the highest concentration of it - up to 8% of the fresh weight in well fed state, or 100–120 g in an adult. In the muscles, glycogen is found in a much lower concentration (1% of the muscle mass), but the total amount exceeds that in liver. Small amounts of glycogen are found in the kidneys, and even smaller amounts in certain glial cells in the brain and white blood cells.
