Peat is mentioned thousands of times a day all over social media. Not like he's some kept secret that a few hundred people know about at this point. I mean, his ideas have spread so far that RFK Jr. is taking ideas he popularized and is going to ban seed oils through his role at the Department of Health, among many other things.
I would definitely credit 4chan with being a big key in what helped popularize him and his ideas though. It was the first place I heard about him, and it pissed me off to be honest. It was a discussion on fitness and nutrition and someone said fish oil was bad and cited Peat. I was mad because I was taking tons of fish oil because that's one of the things all the gym bros said to take. Didn't want to admit I had maybe been damaging my health and had wasted money on it.
I eventually came around.
