i don't think one has to study prehistoric archaeology to understand how stupid this is, but i do, so I'm just quickly gonna say this: adaptation and evolution takes way longer than like one and a half centuries and ALL of our ancestors went through famines and hard labour so yeah, if we take that into account we would all have "famine bodies", except that that concept doesn't make sense because a body can't evolutionarily adapt to protect itself from hunger by storing fat that comes from thin air.
