I think the search for a magic diet is because of the weird industrial food landscape we're in. Most of our food is designed for cheap production, shelf stable storage, and easy distribution. Nutrition and health aren't really considered. People think "everything in moderation" but when the industrial food supply is so far off of the ancestral norm, moderation really isn't the same thing. You're right people will go off the deep end looking for magic cures. But sometimes a little ancestral influence can help guide us. I've been eating beef, salt, water as my primary food for nearly 15 years. Sometimes I may have a potato here and there with my steak or eggs and bacon for breakfast. But I don't have vegetables or fruit otherwise (they just don't make me feel good). I'm pretty ripped for a middle age guy and have tons of energy and no health problems. I would never proselytize or tell people how to eat, but I do like to give my N=1 data point that shows it's not as crazy as it sounds.
