According to another good doc (rymes with "froggin"), the good doc we are ignoring is spouting nonsense:
"This whole notion that it takes a prolonged period of time to reset metabolism (after high intensity) has no physiological basis whatsoever. In addition, who cares? Because you don't have to burn fat to get good at burning fat."
He also says that lactate does not in any way inhibit lipolysis (fat burning).
