The real question is not if it effects your CHO levels but whether or not that makes any difference. There is no evidence that short term changes in CHO levels has any effect on CAD later in life. It simply doesn't matter. And most newer studies show that the lifestyle (sedentary) of those with high LDL has more of an effect on the odds of CAD than the lipids themselves. So having bad lipid profiles if you're an active athlete probably doesn't matter either.
