So according to the IF articles it seems that supposedly being carb-free causes your body to act as if it's in a fasted state minus the catabolic effects (such as mTOR shut down etc.). However, I've seen kiefer still recommend that HIIT and weight training is still MOST beneficial with absolutely zero cals, even fat.
So...what gives? Why would being zero-carb reproduce the same hormonal environment, but not be as beneficial as zero-cal when training is involved? I know that fasted training boosts the GH response 2x, but wouldn't it be the same if all you had before training was some coconut oil?
