First of all, I've talked about healthier lifestyle; exercise is only half of it. Second, and most important, I think you never lived in countries having different lifestyles, so that your idea on the subject is purely theoretical. Nutrition research itself is not "wrong", but it's much more important to have a broader view and experience. Nutritional "discoveries" have been coming and going for decades, and yet the situation didn't improve at all. If you'll have a very simple walk around a city, and possibly in a supermarket, in a country where obesity is not epidemic, you will see immediately why the situation is such.
