I don't think cutting all carbs is the answer. At some point in time everyone will have to go back to eating carbs. And if the only type of dieting you know is ketogenic style then you're in for one hell of a treat when you get off of it. I think most dieters should learn to eat healthy the traditional way, meaning with carbs. Once good practices are built then they can choose to go extreme, knowing that when the day comes that they go back to normal they will know how to do it.
