Paleo is made up bullshit. Paleolithic people in most temperate and tropical regions ate like 60-70% plant foods. The only places where people ate huge amounts of meat all the time are like the arctic.

Keto, I think, was a specific diet for like diabetes or some condition. Same with Atkins. Neither were intended for general use.

Something like 90+% of people who try to lose weight dieting gain back all the weight within five years, and often gain more. Dieting is made up BS. Totally unscientific, unserious nonsense.
