There is a very popular diet going around called Dukan diet, and I hadn't heard of it. It apparently seem to be a variation on the Atkins diet, this time adding more vegetables and leaner meat. I assume this diet is designed to put someone into Ketosis to burn fat instead of carbs as primary fuel. I'm not asking about effectiveness, and personally don't really do well on these types of diets (bodybuilder 40/40/20 seems to work best for me) but I want to make sure I'm talking properly about these. Are all three of these diets (Atkins / Paleo / Dukan) basically variations of the same concept? Thanks!
