Reported numbers vary quite a bit (perhaps in part because the physical activity intensity of training or warfighting also varies), but you might be interested to know that soldiers in training or active duty might hit something like 4000-5000 kcal/day in energy expenditure, maybe thousands more for outlier people and/or circumstances.
A PSA for those who might like to have less body fat: a number of observational and experimental studies find that the energy density of your diet (as in, calories per gram) is a very, very good predictor of ad libitum caloric intake. I doubt that an increase in the caloric density of our diets fully explains the obesity epidemic -- there's probably something to the "hyperpalatability" idea (though hyperpalatable foods are almost always very energy dense too), habitual nicotine and THC intake trends probably matter, I'd buy that some contaminants even if not lithium are causing people to be hungrier or less physically active, etc etc -- but I find it...

I strongly disagree with this interpretation of those overfeeding studies. From what I can tell (though I couldn't access every study SMTM cites), "overfeeding" is usually defined relative to the output of one of the typical BMR/TDEE estimation formulas given a person's parameters, not based on actual measurement of a subject's TDEE. Those formulas are fine for a baseline guess, but even the most accurate ones are going to be substantially off in either direction for a fair number of people! Some of the difference is unaccounted-for NEAT, some of it is differences in absorption efficiency, some of it is probably other factors we don't understand yet. Given the known reality of...

Related to this, I assume? (Don't click that until after you take the survey.)
For a brief period of time, maybe a month or two ago, the favicon for the site was "< X" (less than, then a red X). I liked it more than any variant of "LW" I've seen so far, but whoever actually decides must not have, and unfortunately it wasn't around long enough that many people who you'd hope would get it would get it.
I'd be the first to buy three LW shirts and a bumper sticker if they were ever made.
Shouldn't you ask when the respondent thinks the Singularity will occur before mentioning the year 2100, to avoid anchoring?
I don't think it's accurate to say LW focuses on atheism. Consider: this is the only post whose title involves atheism or any religion on the first page of the discussion section (40 posts, for me).
I predict that the lesson behind this exchange will turn out to be "Don't argue with people who think consciousness is fundamental".
Going off this post of his, it sounds like people who take a daily multivitamin should have dramatically lower morbidity for at least some diseases that aren't already typically associated with nutrient deficiency. Studies on that subject already exist, and I can predict what they'll have to say, though I can't look for them right now.
(This is a subject that appears incredibly important to me, but it's received no discussion on LW from what I can see with a brief search. Please do link to articles about this if I missed them.)
Edit: This is all assuming that the first powerful AIs developed aren't exponentially self-improving; if there's no significant period of time where powerful AIs exist but they're not so powerful that the ownership relations between them and their creators don't matter, these questions are obviously not important.
What are some proposed ownership situations between artificial intelligence and its creators? Suppose a group of people creates some powerful artificial intelligence that appears to be conscious in most/every way--who... (read more)
> A question I have here is, why not try for low calories per litre instead of (or as well as) low calories per gram?
I think calories per gram is usually what people study due to some combination of:
- this is the way somebody chose to measure "energy density" early on and it stuck for whatever reasons things stick
- in cooking and/or conducting experiments, mass is pretty much always easier to measure than volume (even with liquids, in my opinion...)
- we see this metric work pretty well -- better than basically any other known single factor, is my impression -- to predict satiety response, ad libitum caloric itake, diet adherence, and long-term... (read more)
