Important tips here: pick meat cuts that are tasty (which necessarily will have a lot of fat, like the rib eye). Do not pick lean cuts ( gives some people digestion issues) , do not season except with salt. Seasonings interferes with one's taste buds to assess the quality of meat.
I first heard about it on Joe Rogan - Jordan Peterson episode and then Shawn Baker - I'd suggest to hear the latter as he is a an orthopedic surgeon, weight lifter, and is 52 years old. Kinda gives it more credit.
The diet is pretty easy depending on how you want to approach. - it's only animal based food (meat, fish, eggs, milk, cheese). I'd be careful with people who try to sell you something, search around on different ways to start.
I went cold turkey straight to only meat. It's hard, and it takes a few weeks for your stomach to get used to it. But I did it because previously I never managed to keep a straight diet because there were so many choices, so I kept slipping into the occasional sauces, stews, and FODMAPS. It was much simpler to go "okay i can only eat meat"
