The carnivore diet stuff is just straight up garbage fad dieting except it sounds cool or whatever so it appeals to insecure dudes. No real substance to it, and everyone I’ve ever seen promote just spits out the same bullshit claims as every other fad diet testimonial (“no more brain fog”)
Unless you’ve been instructed to by an actual doctor, switching to a meme internet diet promoted by morons like Jordan Peterson is probably not a great idea.
If it works for people so what? Personally, I would never go that far but it seems like most people aren't getting enough protein and could use a bump.
You can see people you care about getting sick by buying into that absurd diet.
Or you care about society in general, as you are part of it.
It's also possible to care about strangers in general - it's empathy.
I don't understand how it is a garbage diet either? You get all the nutrients you need while eliminating pretty much everything else. That to me sounds like an excellent starting ground to then build upon and figure out what YOUR gut is cool with.
