Thought this was mindblowing. A lot of it was familiar to me (e.g. women need a certain level of body fat) and some of it I knew as urban legend (e.g. body fat set point theory).
However, he references studies and talks about things men might experience at 5% body fat that I never expected, like extremely low testosterone.
I like the concept of ActivityPub (though Tildes feels cognitively easier to use). But I actually think internet forums are a dying format; I enjoy them but I don’t want to talk with bots, read bots arguing, or post more stuff used to train bots. I miss having little online corners of nerds being nerdy, but I think a lot of it will have to come offline to remain "authentic."
