That's one of the things that Dr Fung talks about when he promotes intermittent fasting. Not only does he talk about that "it's always been like that," but he also gets into the bodies reaction and the science. And in addition to the practical part that you mention (times without food or less food or needing to find food), he also talks about the fact that pretty much every world religion has promoted fasting for, potentially, hundreds or thousands of years. "We"'ve been fasting for all of history, until relatively recently when refrigeration and preservation got to be so cheap and available that much of the world can eat whatever, whenever and often as much as they want.
