Talking to Collaborator always rejuvenates my enthusiasm for my project, though, because he has a way of talking about our science that is so eloquent. He knows this stuff. It actually makes me a little bit jealous, but I guess that's why he has a PhD and I don't.

The thrust of the article is that thrifty genes have always been a theory, and a problematic one at that, because it shifts the focus of obesity in first nations populations (the Pima Amerindians have the highest prevalence of type II diabetes in the world) from a socioeconomic one (fast food is cheaper than food that is healthy, and is marketed to poor people) to one that is genetic, which sorta smacks of eugenics.
They do mention at the end of the article that there may be a thrifty genotype, meaning that some people do have a higher risk for type II diabetes based on a host of genetic and epigenetic factors, but that it isn't as simple of a problem as localizing a single gene. Something to think about.
