@wester130 Not that I know of. I don't remember running across very many studies measuring DHT unfortunately. Although I would predict you could dig up enough studies to get a sense of DHT levels in the US in the past compared to currently.

RE: countertop reverse osmosis filter
I'm not sure, but reverse osmosis apparently removes minerals from your water that you don't want to remove. I looked into water filters pretty deeply a little while ago and wrote my conclusions here: https://whatwaterfilter.com/perfect-water-filter-family/
From the labs, reviews, and company behavior, I think ProOne and ClearlyFiltered have the best countertop water filters. (they aren't reverse osmosis though)

RE: The Testosterone/DHT Conspiracy
@Crypt-Keeper I know what you mean, however average testosterone levels really have fallen, along with other markers of masculinization, if you believe the research. I did a research project on it a few years ago: https://bioenergetic.forum/topic/470/testosterone-worldwide?_=1722348624010
Some of it is just obesity pulling the average down. But I have also seen a study that says test has fallen independent of obesity. I haven't fully gone through the data myself to look into that.

RE: Defanging your computer
@insufferable said in Defanging your computer:
So for twitter and youtube, I installed extensions to remove all the distracting stuff and make these sites intentional, so you have to type in what you want to see, before you see anything. Youtube and twitter both just display basically a blank screen on the homepage now.
The extensions I installed (on firefox) are "Unhook" for youtube and "Control Panel for Twitter." I also have "BlockTube" installed but I forget if it's doing anything right now or not (I tried it before I found Unhook) And of course I have AdBlock Plus running too.
Control Panel for Twitter stopped working. I use https://xcancel.com/ now, which is even better since you don't have to login to twitter.

Is bodybuilding bad?
I think so.
It's freakish, not beautiful. The desire to get unnaturally big is a psychological problem, people still felt it was bizarre as late as the 2000's. Excess muscle is bad for fitness.
This goes for the 1940's steroid-free lifters too.

RE: Why are women today, the non fat ones, better looking than women back then?
@insufferable said in Why are women today, the non fat ones, better looking than women back then?:
I don't think it's makeup, the generations really do look different. I don't know why.
I think I remember a study that identified how skull shapes (within the same ethnicity) are changing over the last 100 years, but I can't find it.
Just found something:
https://news.utk.edu/2012/05/30/american-heads-getting-larger/
https://pubmed.ncbi.nlm.nih.gov/27737575/Skulls have gotten higher, narrower, longer, and larger apparently.
You can look at old pictures, compare them to modern ones, and you can see the narrower and longer change. I noticed it many years ago looking at old pictures.
I guess it's happening for the same reason people are getting taller, this is the same phenomenon happening to the skull. @Crimkadid on twitter talks about stuff like this a lot.

RE: Sun exposure
I read somewhere that 15 minutes of direct mid-day sunlight on a patch of fair skin will produce maximum vitamin D, more doesn't accomplish anything.
You can get hours of sun outside of tanning/burning hours though (10am-4pm during standard time, which is 11am-5pm during daylight savings time)

Effect of endocrine disruptors on females?
You've seen articles that testosterone has dropped over the decades in men.
I got interested in that and wanted to dig into it, so I did a research project which is linked here - https://bioenergetic.forum/topic/470/testosterone-worldwide?_=1717461794467
From what I've seen, it's probably in large part due to prenatal exposure to endocrine disruptors which cause lasting damage to the developing child. The lowered adult testosterone is just a part of the damage done.
But females are exposed to these same endocrine disruptors. What is the female equivalent of that "testosterone has dropped 200 ng/dl over the last 30 years" story? What lasting damage happened to females in the last few generations?
I've seen studies that say prenatal stress generally produces a lower testosterone male, but the picture is more complicated in a female - some more masculinization often and in a defective way, maybe like PCOS.
I hear PCOS incidence is rising. I'd like detailed stats on that but can't find them. I would like to chart its growth and map its prevalence on the world map, same as I've done for testosterone levels. I would hypothesize that PCOS is highest in pesticide sprayed regions, same as I tentatively found with male low testosterone.
Endocrine disruptors can harm the masculinization of the brain in males, what have they done in females?

RE: New "Mission" of RPF
@SummerPeach said in New "Mission" of RPF:
I wasn't a poster on the RP forum but a long time lurker and couldn't believe what I was seeing when I visited the forum recently. The whole thing reeks of a subversive and organised take over. People that are new to Ray Peat's work will visit the website and get caught up in the anti Vit A "low toxin" nonsense. They will see the RP admin rejecting coffee, dairy and orange juice. Seems like such a betrayal and it doesn't make sense to continue to call it the RP forum unless subversion is the goal.
How do they explain the good health of Danish people if Vit A is toxic? Danes are given leverpostei (liver pate) as toddlers and a lot of Danes eat it a few times a week, all their lives. Compared to citizens of other European countries, Danes seem strong and healthy with good hair, teeth and bone structure.
Interesting! Denmark is one of the few parts of Europe that has partly avoided the worldwide testosterone decline.

RE: Testosterone
@HyperTorless said in Testosterone:
@insufferable Very interesting article.
It should be noted that the !Kung San are the only hunter-gatherers who had prediabetic range of glucose tolerance. It is most likely due to their unreasonable consumption of the mongongo nuts (sometimes 80% of their diet), which contains 40% linoleic acid, especially as the glucose tolerance test were conducted during the season where the mongongo fruits come ripe for consumption.
Surely the PUFA didn't help to ramp up testosterone.Great info, thank you! I approved your comment on the site.

RE: Do you have to be fasted for accurate blood test results?
Looks like testosterone drops quite a bit after eating.

RE: Defanging your computer
I like incandescent lights but I notice when I use my e-ink screen under incandescents, my eyes hurt a bit. When my screen is lit by daylight through a window, my eyes don't hurt. Reading a book under an incandescent feels good though.
My screen has a glossy coating and I'm pretty sure it's reflecting the IR light from the bulb into my eyes. My eyes definitely hurt less when I angle my screen and my light so that it won't reflect the bulb's light straight into my eyes so directly.

Iron - good or bad?
Ray doesn't like too much iron.
https://raypeat.com/articles/articles/iron-dangers.shtml
I don't agree with this. In the past I've experienced anemia symptoms that resolved when I ate more iron rich foods (meat and blackstrap molasses) so I have no interest in reducing iron.
What do you think?

RE: Thyroid supplements leading to lack of drive & deteriorating energy
If I understand correctly, your TSH got worse after 6 months of Peating? Whatever you were doing, maybe you should try stopping.
Have you got iron and red blood cell lab work? Perhaps they are low? I disagree with ray about low iron being good. Do you avoid meat now?
No morning sun always gives me an unpleasant sort of prickly feeling like static in my head that I (very unscientifically) associate with prolactin. I've found light to be very important for me, it really makes a big difference.
Are you on your computer a lot?
