A few thoughts:
>"Dried seaweeds and sea veg. weigh almost nothing. I imagine the heaviest are un-soaked sunflower seeds, which are a minor part of my ziploc."
Not sure what the OP means by "weigh almost nothing" and "heaviest." The nori in my cupboard contains 56 cal/oz. Sunflower seeds are ~165 cal/oz. And if the OP wants to carry part of his water in the form of sprouts, that seems a reasonable indulgence for the sake of fresh veggies, but it clearly isn't a weight savings.
>"One can eat a tube of peanut butter and run all day, no stove required."
Uh, how big is that tube of PB? 8 oz is more than I could choke down at a sitting, and that's still only 1400 cal. @ 175 cal/oz for PB. That's a pretty significant calorie deficit for hiking all day, let alone running.
>"Don't forum members jerk beef, smoke fish, dehydrate fruit, carry gorp, etc?"
Sure, but lean dried meat or fish is never going to be much above 100 cal./oz, if that. Dried fruit, even less. I like the taste of dried fruit and jerky, so I carry it anyway, even though it's a little "heavy" in terms of calorie density.
>"…perhaps there are a few guilty consciences here."
I doubt it. I've been reading the articles and forums here for a couple years, and it seems like plenty of BPL folks choose to go stoveless from time to time, or are curious about doing so. And I'd guess the majority here don't cook during the day (just breakfast and dinner), meaning half our calories (or more) already come from cold foods. That a person can go three days (or even much longer) without cooking is hardly a revelation.
In my experience, discussion of cook vs. no-cook on these forums is typically respectful, interesting, and fact-based. A pity the OP's "question" (and his follow-up posts) wasn't any of these. But I did laugh a little.
