Shame the dietician can't even follow or agree with her own advice:
"performance plummets because the sugar burners are so pumped up on adrenaline, which drops drastically after halftime." The best thing an athlete can do is to go through the metabolic shift induced by a low-carb diet.
So funny how the "fat causes heart attacks" line is always included in there at the end. Might as well say "And the teeny fat fairies will still chew on his heart if he eats fat" because there's about as much evidence.
