Sure, but keto says it totally fine to eat a steak and a stick of butter and nothing else. That doesn’t seem sustainable.

Yet it is, we only need to look at the documented human populations that only had access to animal food before westernization. They sustained, even thrived.

Also I’ve never met anyone that does keto that allows any carbs.

Keto is just metabolic ketosis, any biological state while the body is producing detectable levels of blood ketones. Anyone can achieve it <20g carbs per day, and many people have higher tolerances (age, muscle mass, resting metabolic rate etc).

Just trying to offer insight into the down votes. I don’t think it’s the IF crew doing it. It’s probably people who are anti-keto.
