If there are long term studies, if there is proof about long term damage from low carb, let's see them. Of course, I don't expect any because there aren't any.
We do have various studies of peoples who traditionally eat a low carb diet. The Masai, the Inuit, the Samburu, all live primarily on meat and fat and have remarkable ststes of health as long as they don't start eating a "modern" diet.
