I don't think the difference in conversion efficiency between carbs and fat is relevant in a "normal" diet. The main difference is in how they are metabolized, and the effect they produce in the body.
I can only recommend everybody to stop loading huge amounts of carbs, specially sugar. Go for simple unprocessed foods, like fruits, vegetables, meat, fish, and so on.
The paleo lifestyle works just fine for me. I know it is hard to convince other people to do it. Even when they see me eat like I do, and they have seen the change in other people that adopted that practice, most people simply resist the idea.
