thats why they say its imposible to out-exercise a shitty
diet 
there are outliers, but those are the exception, of course.
Yeah..... Phelps can only do what he did because he burns pretty
much everything he eats.... he eats a lot to fuel his heavy-duty
daily workouts.
The flip side of this is that as you get more active, you gotta
eat more if you want to function normally.
I remember reading in these forums about this dragonboating girl
who complained about fainting spells even though she claimed to be
meeting the 'daily WHO minimum' of 1200 calories.... well duh, if
you're eating so little while being so active, of course you end up
with fainting spells....
