I've tried all kinds of systems for planning, preparing, and eating backpacking food. At one point, I could tell you how many calories, how much fat, how much protein, yadda, yadda, for every part of my backpacking diet.
Useless. Totally useless.
Old Army saying: Doesn't matter how many calories you give a man if he won't eat it.
Absolute truth. Start there.
Here's what worked for me, and what I'd like to try for future trips.
