Laurie, two things.
First, considering that you recently stated that you don't know very much about paleo, and haven't read very much about it, I would think that your statement here is very much a blanket statement based on lack of knowledge of it. The author of the article was trying to soften the oft inflexible outlook that many paleo adherents have and if you read more of his articles you'll get a better understanding of where he is coming from. Remember he is addressing paleo adherents, not people like you who obviously don't put any stock in the whole way of thinking. That's your take, of course, and no one is pushing you to follow this. But for people who do want to follow it and feel it has something important to offer, this article is helpful for those having trouble with it. It's working for a lot of people. I've never followed any fad before, but this has made a big difference for me, and I really don't care what pigeon hole name people want to label it; as a method of controlling my health I'll take what works. Nothing before ever did. Certainly not what you are advocating... which is what I religiously followed for 30 years, with no improvements at all, especially after getting diabetes. Mind you, I was never overweight until I started taking insulin.
Second, there are a lot of cultures around the world that did not often have obesity, where from before recorded history being fat was considered a beautiful and unusual state to be in, namely because it was so hard to achieve and a sign of opulence. Paleolithic people were no different from us in intelligence or cultural tendencies like ceremonies and basic social structure, so it shouldn't be a surprise that they upheld certain people in their societies who were more powerful and wealthy. Those who could afford the luxury of getting fat probably often did indulge in it. Or maybe that woman on whom the statue might have been based was an anomaly, something so rare that, like often happened in Eastern cultures with children who were mentally handicapped, she was revered and worshipped as a god. Or maybe the statue was purely imaginative. Who knows?
I'm not sure what your point is about the statue. Is it concerning obesity and how paleo helps you lose weight? Some people who eat paleo do it to lose weight, but most adherents tend to do it long-term, long after the weight has been lost, to maintain a strong sense of health. Paleo is not just a way of eating... it also equally incorporates certain ways of exercising, a commitment to reducing stress, getting proper sleep, and even making sure to incorporate play. It works much like the components of UL backpacking... it's a system with each aspect of your lifestyle contributing to your health. One reason I like it is that it is comprehensive and doesn't just focus on food.
Without getting more involved and reading and participating in the books and online discussions of paleo, you wouldn't know that it is constantly evolving. Through proper scientific research older ideas are scrutinized and certain old beliefs are either confirmed or found to have problems. Many paleo discussions have centered around the different findings that adherents have had with such things as potatoes, quinoa, and milk, all things that in the early days or in the strict school of paleo were considered off limits, but which, through experimentation and experience have been shown to pose no problem. Remember, the reason paleo is called paleo is to try to emulate a period in human history during which our bodies reached the height of direct interaction with our surroundings, before agriculture allowed us to start becoming independent of the vagaries of that environment. The advantage of this is that this attempts to find a state in which, genetically, the environment shaped us to optimal physiological adaptation due to natural selection. No one is saying that agriculture wasn't a huge advantage to us, but ongoing archaeological research has found a lot of evidence of a great decline in our health ever since agriculture began wholesale. Take a look at the research going on at Jonzac, France, by Paleolithic anthropologists, Dr's. Mike Richards and Shannon McPherson of the Max Planck Institute for Evolutionary Anthropology, the studies of Gary J. Sawyer at the American Museum of Natural History, and the work of Leslie Aiello of the President Wenner-Gren Foundation for Anthropological Research... all of them, in the studying the remains of Paleolithic people and early Neolithic people have found generally optimal health in the former and many signs of deterioration in the latter. Dr. Aiello even states that Homo Erectus, just before our species, represented the highest point in human physiological development. They have all found that as agriculture progressed the variety in what we ate gradually decreased, until today our choices in food have been severely restricted to the few vegetables, grains, tubers, meats, dairy, and fish we eat today. Hell, even the variety of food Japanese ate when I was a child changed dramatically over the last 40 years as western eating habits took over Japan... and the sudden and heretofore completely alien to Japanese culture, obesity epidemic. Japanese ate rice before that, but never in large amounts, because it was for centuries a luxury (even when I was a boy in Japan few people could afford to regularly eat sushi). The Japanese diet consisted mainly of a huge variety of vegetables and fish, with rice as a small aside and much needed carbohydrate source. I almost never saw fat people in Japan when I was a boy; now they are everywhere (though there is debate about rice being a culprit grain in paleo. It doesn't seem to have the effects that wheat does).
My point being paleo is far more than just a simplistic "no carb/ lots of fat" trend diet. There is healthy debate going on and experimentation and involvement with many serious, peer-reviewed scientists. If grains were found to be optimal, that's what paleo adherents would eat, since the point is to seek the optimal diet for humans, not advocate certain dogma. That is what attracted me to this whole movement in the first place. .
