The amount of carbs you find in the chart in the back of the book is the baseline, meaning it’s the maximum amount of carbs your muscles can hold. So like mentioned above, spreading it out throughout the week/training is probably a good way to do it. It depends on how intense your training is and what kind of training it is too. Although I could easily do 600 g in an hour or two with things like rice and bananas… and yes, not the proudest thing, but I have done it before. Normally I don’t get the satiety signal like normal people, but getting in ~700g in two-ish hours did make me pretty full.
Anyway, for a starting point, I think that 1~2g/LBM is good. Depending on how you feel, you can adjust up or down.
