Afaik there is no top athlete on keto when performing: they are all on high-carb.

Keto is the "burn your body fat" mode. Staying in keto by eating high fat low carb is a trick. Humans never had such easy access to fats as today. Before we made settlements we got a large part of our calories from fruits (which contain short carbs), not unlike the other primates.

This can't possibly be true. Agriculture is only 12,000 years old or so, but people have been living in Europe for much longer than that. I'm in North America, and there are no fruits available locally for six months out of the year. Before agriculture people must have been living mostly from hunting.

You think a large share of pre-settlement humans lived in non-(sub)tropical regions? I don't think so. We mostly staying in the warmth, and the few daredevils that left had a hard time.

You know the dietary practices of "all" top athletes?

Athletes in sports favoring fast-twitch muscle presumably wouldn't do keto, but endurance athletes, sure.

The SF Giants' Hunter Pence is a vocal keto practitioner.
