Downvoted means you agree (on this thread), correct? If so, I've wanted to see a post on rationality and nutrition for a while (on the benefits of high-animal fat diet for health and the rationality lessons behind why so many demonize that and so few know it).
I was worried people would think that, but if I posted links to present evidence, I ran the risk of convincing them so they wouldn't vote it up! All I've eaten in the past three weeks is: pork belly, butter, egg yolks (and a few whites), cheese, sour cream (like a tub every three days), ground beef, bacon fat (saved from cooking bacon) and such. Now, that's no proof about the medical claim but I hope it's an indication that I'm not just bullshiting. But for a few links: http://www.ncbi.nlm.nih.gov/pubmed/19179058 (the K2 in question is virtually found only in animal fats and meats, see http://www.westonaprice.org/abcs-of-nutrition/175-x-factor-is-vitamin-k2.html#fig4)--the pubmed is on prevention of heart disease in humans http://wholehealthsource.blogspot.com/2008/11/can-vitamin-k2-reverse-arterial.html shows reversal in rat studies from K2 http://trackyourplaque.com/ -- a clinic that uses K2 among other things to reverse heart disease note that I am not trying to construct a rational argument but to convince people that I do hold this belief. I do think a rational argument can be constructed but this is not it.
Eating lots of bacon fat and sour cream can reverse heart disease. Very confident (>95%).
Just to add to the anecdotal data, I've had the same experience upping animal fat and being able to be productive (mentally and physically) even without eating, and I work a physically demanding job at night, either of which alone can induce fatigue. I eat mostly butter, egg yolks, cream, coconut oil, and fatty cuts of meat like pork belly and fatty ground beef (epsom salts, mineral water and magnesium supplements take care of any muscle soreness).
Not AT but something similar and free online vids is "Intuflow", for example http://www.youtube.com/watch?v=bsMPqP7hxRk
T&C report that mapping the Wason selection task to examples from everyday life doesn't improve performance, only when changed to detecting cheating does it change performance.
If I understand your last sentence correctly, that was my other main problem with their argument for evolved social contract algorithms or whatever: I didn't see sufficient evidence that the "cheating" stuff was part of our "native" architecture rather than a learned behavior. Hence the suggestion to create tests that vary on things we know to culturally vary.
Well the EvPsych Primer referenced uses it as their centerpiece for how EvPsych works. I can't say what the rest of the literature says.
Not just hold the belief but eat that way even more consistently (more butter and less sour cream just because tastes change, but same basic principles). I'm young and didn't have any obvious signs of heart disease personally so can't say it "worked out" for me personally in that literal, narrow sense but I feel better, more mentally clear, etc. (I know that's kinda whatever of evidence, just saying since you asked).
Someone else recently posted their success with butter lowering their measurement of arterial plaque: "the second score was better (lower) than the first score. The woman in charge of the testing center said this was very rare — about 1 time in 100. The usual annual increase is about 20 percent." (http://blog.sethroberts.net/2011/08/04/how-rare-my-heart-scan-improvement/) (Note: I disagree with the poster's reasoning methods in general, just noting his score change.)
There was a recent health symposium that discussed this idea and related ones: http://vimeo.com/ancestralhealthsymposium/videos/page:1/sort:newest.
For those specifically related to heart health, these are most of them: http://vimeo.com/ancestralhealthsymposium/videos/search:heart/sort:newest
