Here's an article I wrote on the subject.
Why is there Feedism?
An Evolutionary Explanation
In "The World Until Yesterday: What Can We Learn from Traditional Societies"? Jared Diamond describes some traditional societies-- they don't call them "primitive" anymore--that have periodic food shortages. The people gorge themselves in times of plenty to gain weight to get them through lean times. In such places Feedism would be adaptive and be selected for.
Of course, in many societies (including modern ones) they figured out ways to store food so they didn't have to do the gorging thing. Storing food in a granary or whatever is usually much more practical than storing it as fat on your body. So genetically I figure we're a mixed bag. We have ancestors from both kinds of societies. So some of us have Feedist tendencies, some don't.
I imagine those tendencies will dwindle over the coming millennia since gorging and gaining is no longer adaptive. But we won't be around by then anyway!
