"Genetic changes don't happen in a few decades as the obesity epidemic has..." But lifestyle changes do. All of my ancestors were farmers up until my father's generation. And my grandfather's was the first one to have something like a tractor. Even then, it was mostly manual. Now studies have shown that Texas farmers were on a 3500-4500 calorie a day diet in the 1800s, and that probably was true in the early 1900s also. Even then, it was pretty marginal for many. So an efficient metabolism was a big plus. Not so much, any more. Where my ancestors were rail thin through out their lives, many of my relatives are far from that. Even the ones who farm. It takes pretty close attention to both diet and exercise to keep from becoming balloons. Even then, many carry more weight than they should.
