@Liv_Boeree @paulg @balajis @waitbutwhy Uh, @mold_time gives *literally no reason* for why they dismiss the scientifically mainstream explanation of the effect of altitude on body weight: that it is caused by hypoxia (instead of by lack of contaminants).

@ObserverSuns Ford et al. (2007), looking at data from 1980-2000, estimated that “47% of this decrease was attributed to treatments,” and 44% to “changes in risk factors, including reductions in total cholesterol (24%), systolic blood pressure (20%), [and] smoking prevalence (12%)”

@mold_time I think I'll finish the thread here! Of course, you can look at my blog post for more. Oh, one more thing: I think it's really bad that there are several falsehoods in @mold_time 's posts that they have refused to fix despite being told about them.

Hot take: natural eyes usually work just fine, & maybe our civilization should be better organized around that biological fact (by, e.g. not using glasses, microscopes or telescopes)

I’ve seen a few people making this claim (that there are more underweight people nowadays), so I wanted to point out that it is false. From 1975 to 2014, “global prevalence of underweight decreased from 13·8% (10·5–17·4) to 8·8% (7·4–10·3) in men […]”

But we CAN expect to see certain statistical signatures, which may appear even in pretty small datasets In humans, the obesity epidemic has been matched by an increase in the variance of BMI, which means more people who are overweight AND more people who are underweight

4. Serum lithium concentration data likewise shows that lithium exposure is very low in the general population. In Canada, the median is 4,000 times lower than the lower end of the therapeutic range, and the 95th percentile is 1,383 times lower.

@yishan Another experiment described in the same article found that Sprague-Dawley rats with BCS3-L1 got a similar caries score to those with no S. mutans at all. But their caries score was not 0, indicating other bacteria were still causing cavities.

@balajis @mold_time These blog posts are repeatedly misleading. For instance, they literally make up the “fact” that wild animals have been getting more obese out of thin air (none of their sources show that) . 1/x

“Wild animals are getting obese” is very misleading. @mold_time attributes the claim to this paper several times in their blog, but the paper only investigates animal populations living close to humans. 1/

What are the best Twitter accounts, Manifold markets and websites I should keep track of to know how much of a big deal this is going to be? I.e. how many new multifamily housing units will be counterfactually added in CA?

Therapeutic doses of lithium do not seem to cause enough weight gain to explain the obesity epidemic. (1/x)

Disclaimer: I think at least 80% of SFF's most recent grants range from good to excellent, but for community epistemics it's more valuable to point out disagreements with grantmakers.

@mold_time But in that passage, they're confusing the effects of overeating for a few weeks (as people do in overfeeding studies) with those of overeating for decades. I don't think I need to use a lot of words to explain why that is flawed reasoning.

@mold_time If we actually try to make an educated guess on whether 456 extra kcal/day is enough to explain the change in avg body weight, we not only find that it's enough, but we find that it is way too high. Let me explain.

Apparently @mold_time received a $100,000 grant from the Effective Altruism Infrastructure Fund last year, on top of their $345,000 Survival and Flourishing Fund grant.

Somehow the Survival and Flourishing Fund was impressed enough with this level of brilliant scholarly research that they recently recommended a $345,000 grant to @mold_time . (This was announced last month, in . @mold_time is "Whylome, Inc.")

But people who promote diets want to believe that **their** diet is special and unique and holds the secret key to effortless weight loss and is perfectly safe and has a ton of health benefits and the medical establishment has been lying to you about it for decades

@ESYudkowsky I’d imagine a fairly sizeable chuck of the EA community (unimportantly, including me) is worried about *both* chickens *and* things like GPT-3 being sentient and suffering.

@mold_time Moving on to the next point. @mold_time for some reason argues that the contaminants that supposedly caused the obesity epidemic also cause anorexia in a small # of people as a paradoxical reaction, and that that is why there are supposedly more underweight people today.
