I seen this story on "Caveman diet's" today, from May 12th.
The story says that nothing can really be gleaned from the results because the study was not controlled. That is absolutely true, but what they fail to mention is that a controlled study of a paleolithic diet WAS performed AFTER the study that they mention in the story. I linked to this study on this very blog
Another criticism of the study was the low calcium intake. However, this only looks at the input side of the equation. Whenever you eat a food, it reports to the kidney's as either a acid or alkaline load. If you have a high acid load diet then body needs to buffer this acidity. How does it do that? One way is by leeching calcium from your bones because it is one of the bodies biggest stores of base/alkaline. So, while a paleolithic diet may not have much by way of the input side of the bone density equation, it makes up for it by not losing any. Furthermore, studies of the fossils of our ancestors show that they had very dense and strong bones BEFORE humanity started consuming milk. After humanity started consuming milk our bones became WEAKER. This was due to the fact that we had started consuming grains as well. Grains, along with dairy, meat, and legumes, are acid producing foods. Vegetables and fruits are the only base producing.

Bogus news article on "Caveman diet"

Does fat make you fat?
Who's this guy?
That would be Mark Sisson from Mark's Daily Apple.
According to Mark's post today, he eats 58% of his calories from fat. You heard that right, 58%! How does he get by with it? Simple, fat doesn't make you fat. So long as the fats you are eating are healthy, there is absolutely nothing wrong with that. In fact, eating more fat may curb hunger because fat, along with protein, is more satiating. Carbohydrates on the other hand are more likely to induce hunger through blood sugar swings, and thus potentially lead to more weight gain.
Anyways, at 54 years of age, Mark is proof that (1) you can be over 40, let alone 50, and still look great! And (2) eating fat does not necessarily make you fat.
