Actually, when they say that low-carbing was never tested, I think they're right. Most of the studies that tried to look at the affects (positive and negative) of fat, studied fat in a high-carb diet. They did not study it in a low-carb diet, which, as we know, shows the true benefits of fat. Finally, they are starting to study low-carb diets and finding what we all know to be the true natures of fat and carbs.

So now, when they are finding the true benefits of fat, they're surprised. And no wonder.
