> IMO: because we have always had nowhere near enough food. Agriculture revolution was what, 10,000 years ago? That's a blip.
I think its the opposite, agricultural is much more reliable food so then population could grow until everyone barely starved. Before then people either had more food than they could use or they just died from starvation, people generally lived better lives before agriculture but there were much less people.
The reason we grow fat is because its good to be fat when you are a hunter gatherer, since there is more food than you can possible eat when you kill a large animal you just eat as much as you can, and then you survive better if you don't find another kill for a while.
Agriculture only started to produce enough food for everyone when we human stopped multiplying, before then starvation was only a few generations away as people would multiply exponentially until there isn't enough food again.
