But it doesn't seem likely that this is what our biology is adapted to. I think we're primed to function at optimum parameters on a baseline food abundance, punctuated by brief intervals of scarcity. I think that's a much better model for how our very distant ancestors lived. I don't think we're the descendants of those who lived in scarcity all the time. But it's quite likely that the hunting-gathering life had its periods of lean caloric intake regularly.
