Here's a good article that looks at hunter-gatherers and obesity. It points out that when hunter-gatherer populations are introduced to refined carbohydrates, they suffer obesity. Specifically, they suffer "truncal" obesity, or insulin resistance. The authors point out that modern humans often have trouble with refined carbohydrate, as evident by the high rate of diabetes in Western populations.
