I'm not convinced that human bodies somehow started to work in a very different way over the span of just a few decades. The amount and composition of what we place inside those bodies did change though. Just like in times past, people tend to eat as much as they can, and do as little physical work as they can, in the extreme. It's just that we're all so incredibly wealthy now compared to our ancestors that this is no longer a reasonable strategy for maintaining a healthy weight.

It is probably a big part of the story, but maybe not the whole story. There are examples when abundance of food does not lead to widespread obesity, so the particular types of food being eaten must be of importance. Kitavans are not particularly active. They have an activity level comparable to a moderately active Swede, the population to which Dr. Lindeberg draws frequent comparisons. They have abundant food, and shortage is practically unknown. Their good health is probably not related to genetics, since genetically similar groups in the same region are exquisitely sensitive to the ravages of industrial food. Furthermore, the only Kitavan who moved away from the island to live a modern life is also the only fat Kitavan. http://wholehealthsource.blogspot.com/2008/08/kitavans-wisdom-from-pacific-islands.html http://wholehealthsource.blogspot.com/2008/08/kitavans-wisdo...
