I have to disagree also with your second point's validity. Fat can be burned effectively with 0% of your diet coming from carbohydrates. You will do so as long as you are doing the following: getting adequate calories from proteins and unsaturated fats and getting enough rest and exercise. Even if your goal isn't to burn fat, for instance to compete in marathon races, you can still utilize fats for your only source of energy production so long as you follow the rules for endurance fueling.

But diets like this should be restricted only to the carbohydrate sensitive because, in practice, it is tough! Getting used to it takes about two weeks. The foods are lean meats/shellfish and nuts/oils/seeds. I used to love peanut butter. Now not so much. But it's a price I'm willing to pay since the alternative is feeling like crap after eating any type of carbohydrate and being tired all day. Now I have gobs of energy and endurance is not a problem.
