The Darwinian Diet

How nature aims to protect the curves on women's bodies.

Diet

It's no secret that we need calories to fuel our body's basic energy needs. Yet many of us find it difficult to take in the right amount—and the right kind—of fuel. No matter how many guidelines we're given, we still crave what we know is bad for us.

Evolutionary Psychology

Our bodies evolved over eons, slowly calibrating to the African savanna on which 98 percent of our ancestors lived and died. So, too, did our brains. Evolutionary psychology postulates that the mind is shaped by pressure to survive and reproduce. We jealously guard romantic partners and cherish our closest relatives above all others, lest we fail to pass on our genes.
