"I'm surprised many believe this. It seems self-evident that our bodies are well adapted to periods of starvation. Any biology that wasn't so adapted would have been out-competed by those did."
I actually never thought about it from that angle. It seems like it should obviously be true now. Now the question is how true and if nuances exist where our bodies can take it but not optimal in health.
Yea, that's the key imo. Just because our bodies were able to deal with it does not mean it is optimal.
I think our current understanding of medicine and human biology is quite limited, so there may be tons of these little quirks - non obvious things that are actually amazing for us. But, i'm sure there will also be tons of things that are not directly related to what we did to survive thousands of years ago.
