[QUOTE="LittleGreyCat, post: 2358117, member: 6467"] Think about this for a minute. No limit? That is obviously ridiculous. First Internet hit says average 500 grams of glycogen is stored if not fasting/low carb: "Of this, around 400 grams, or 1,600 calories, are in your muscles and about 100 grams, or 400 calories of glycogen, are stored in your liver." As a T2 I get the exercise hit even when I am low carbing and mainly in ketosis. Possibly worse in ketosis. My theory is that I'm not burning glucose because I am burning ketones but my liver hasn't realised so it keeps chucking glucose into my blood stream. I am assuming that if a T1 is eating normal carbohydrates and matching with insulin then the glycogen stores will usually be full. Low carb/keto T2s will probably have shed much of the usual glycogen store - that easy 4 lbs you take off at the start - but there will still be stores because the liver has to create glycogen (gluco-neo-genesis) to feed parts of the brain and other bits and pieces which can't utilise ketones. Keto adapted people still have a BG level! [/QUOTE]
