"I wonder about that … there is certainly lots of room for variety, but the basic underlying weight data is pretty constant — carbs are a fixed number of calories per ounce, as are fats and protein. That's all you have to work with.
It seems to me that, for any given number of required calories, you can calculate pure carbs for the required calories and you will have the maximum food weight; calculate pure fat and you'll have the minimum weight. The best you can do is to get as close to the light end as you can while still being palatable and meeting any other needs (protein replacement, fiber, quick energy, …)."
Hi Bob,
Precisely. The impression I get from the threads on food has been that the importance of getting as close to the light end as possible is often overlooked in favor of concentrating on reducing gear weight, carrying gourmet or semi gourmet food that requires more fuel(think extra weight) to prepare, and possibly overestimating the required calories/day. Mike McClelland maintains that 1# 5 oz food/day is adequate for most people, and I agree with the caveat that calories do vary with body weight and individual metabolism to some degree. I go in with 1# 4 oz/day, but I weigh only 137# and add 3-4# of extra fat in the weeks before a long trip to cover the calorie deficit. My basic point is that, if one wants to lighten their load as much as possible, they would do well to pay as much attention to food as they do to gear. The possible savings are considerable. For example, I used to take 1.5#/day. On a 10 day trip that works out to an extra 2.5# that I no longer carry. Eye popping numbers for a gram weenie.
