I actually linked to something that would have added to the discussion... but it was from a bodybuilding forum on a competing website... and I was told I can't do that and the comment was deleted.
What it said was that fasted cardio misses the point... here's the quote without the link (Alan Aragon)
"On the surface, it seems logical to separate carbs from cardio if you want a maximal degree of fat oxidation to occur during training. But, thereâ??s the underlying mistake - focusing on stored fuel usage during training instead of focusing on optimally partitioning exogenous fuel for maximal lipolytic effect around the clock. Put another way, itâ??s a better objective to coincide your carb intake with your dayâ??s thermic peaks, where insulin sensitivity & lean tissue reception to carbs is highest. For some reason, this logic is not easily accepted, nor understood. As we know, human physiology doesnâ??t always cooperate with logic or popular opinion, so letâ??s scrutinize the science behind the claims."
So I guess that's the point I was trying to discuss in the first place.
