Out of curiosity, I googled it, and it's seems like a restrictive version of lower carb Paleo, like eating all the protein that you want, then 3 tbs of oat bran (hugh?)...I'll just stick to Primal, which works for me!

I actually gave Dukan a try back in the day. It emphasizes low fat, pure protein. Really just lean meats and low fat dairy during the induction. I personally am an advocate of lowish carb or low glycemic, but I think micro nutrients are important. I guess I view Dukan as something to slash water retention and higher carb tendencies whereas paleo is a sustainable lifestyle diet.
