We Can’t Blame Obesity On Our Hunter-Gatherer Ancestors Anymore
Hmm… looks like maybe supporters of the paleo diet are onto something, despite some possible problems with it.
One popular idea to explain the current obesity epidemic proposes that our hunter-gatherer ancestors had a fat-storing adaptation, which allowed them to survive frequent famines. Today, with our overabundance of food, this adaptation is causing us to get fat. There’s just one problem with this idea — research now shows that hunter-gatherer societies aren’t necessarily prone to food shortages.
