2. During winter camping increase fats to 40%
The problem with fats:
"At high altitude (and in extreme heat too) anyone's appetite is liable to falter, and fats may not be too appetizing. A possible reason: fat needs more oxygen to "burn". At high altitude you may also abhor the thought of protein."They, Fletcher and Rawlins, recommend compensating by carrying a variety of choices, sweet things being the most palatable.
