> 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.
