David,
If you find it arrogant for me to question whether I might be too indulgent in carrying a stove for this short a period when it's likely unnecessary, you possess a rather twisted view of humility. If you think that I, as a trail runner, am arrogant for seeking out the advice of others more experienced than I am in backpacking, rather than just sticking with my own gut feeling, or my sport's fashion dictates, then your view is even more confused. If people took my simple word-play ("ultralight" > "ultra-indulgence") so harshly, then perhaps they themselves feel their own behavior flawed. They can own it like adults, or whine like children; not up to me.
As far as the "Facts" go, if you believe caloric intake is the primary factor in determining whether a person is in nutritional deficit after 3 days, whether running or walking or playing chess, then I think you are mistaken. Calories do not equal nutrition, as most bagel-eaters by now know. If you believe that one can't run for 3 days (or a lifetime) on a low-calorie diet, then perhaps you might want to investigate some of the science on reduced-calorie diets, it is extremely interesting. That however was not the subject of this post, and neither was there any dietary "revelation" intended. It's precisely this obviousness (that one can go for 3 days without cooking) that led me to question why. If you yourself find this obvious, your "factual" rebuttal becomes empty if not fallacious.
I do apologize for wasting everyone's time, but I could anticipate the response I'd receive in a running forum. The response I've received here I certainly did not anticipate.
Ciao~
