I absolutely don't care what he chooses as his diet, but I find it hilarious that he picks probably the worst meat in terms of societal impact, carbon emissions, factory farming conditions,cost, and dietary recommendations.
While I think the carnivore diet is dumb and don't dispute the environmental impact of factory farming beef is definitely not the least-recommended for health reasons. It's vitamin-rich and doesn't have a high amount of Omega-6s like chicken, and if it's grass-fed you also get more CLA as a bonus.
He isnt even a big fan of it and said he doesnt recommend it for most people. He is doing it for specific purposes after his daughter tried it.
