Has anyone ready this book "Mean Genes: From Sex To Money To Food: Taming Our Primal Instincts"?

I read it about a year ago, and I found some of the arguments compelling. His main argument, as I understand it, is that our brains were hardwired for a time of scarcity (think caveman days). In those days if you came across something sweet (which was probably rare), having a programing that say "eat up & as much as you can" was probably the correct programing to have.

Nowaday, where sugar is everywhere, that same programing makes it hard to do/eat the right thing.
