Other, much dumber nutrition cranks like Anthony William and Gary Null have Wikipedia pages. Fundamentally, the purpose of an encyclopedia is to be the place that you go to when you hear a concept and want to look up what it is.
You are welcome to join the conversation and try and convince everyone maintaining Wikipedia that random peoples' tweets should be considered a reliable source. Both those other people you mention have been mentioned multiple times in various reliable articles (see the bibliography), while the only thing I can find online about Ray Peat is something that looks a whole lot like blogspam on usnews.com.
For me, it seems obvious that Ray Peat is not particularly notable — even if his self-published manuscripts made him a sort of personal hero to a handful of niche micro influencers on one of the big four social media websites. A quick google shows that he did not “come up with the seed oil craze”

If I had to guess what’s happened here, it looks like maybe some right-wing micro influencers tweeted that Ray Peat was more notable than he really was and those tweets weren’t convincing to Wikipedia editors.
It is good to have notability standards, even if somewhat arbitrary. It protects the site and its editors from being obligated to document and take seriously every silly thing that nano-celebrities and trolls try to will into existence through their tweets.
Especially since there is already a website for exactly that, grokipedia.
