I got this in my email today, which pertains to this discussion.
Adrian Ballinger and Everest
The man mentioned, Adrian Ballinger is already a world class climber. He was attempting to climb Everest without supplemental oxygen and had to turn back. Subsequent testing showed that he was relying on carbs and became glycogen depleted causing his hands and feet to get cold.
With some changes to his training and nutrition, he drastically altered his aerobic threshold and changed what his body prefers for fuel.
Now keep in mind a large portion of the climb is in the death zone, meaning there is not enough oxygen to sustain life. A climber must quickly summit and turn back or die.
So with that in mind, oxygen is a very precious commodity, if the need for extra oxygen when using fat for fuel was an issue, this is the place you would see it.
