Working on a theory of glycogen and caloric surplus/matching/deficit. My theory is that glycogen stores are somewhat related to carbohydrate consumption (how full the tank gets) but also to caloric status. My theory is that eating at a surplus of calories even on low carb will fill the glycogen stores higher than the “normal” keto level.
This explains to me the wide fluctuations in weight that I and others see when we gain or lose 5-7 lbs in a few days. In fact, I think it’s pretty easy to gain in a day or two and might take some days to lose again what was gained in that day or two. The reason is that glycogen stores can get filled quickly but unless you are at a caloric deficit they won’t get drawn down.
Explains the “LBM gains” people have when they increase their caloric intake. Normal body water amount vary greatly along with the glycogen.
