My claim is simple. Sugar and it's higher form, carbohydrates, especially as expressed in processed foods is killing people. The obesity in the USA is directly and primarily caused by this.
Whether or not eating pure unadulterated protein in the form of STEAK, pork, chicken, fish, eggs is the best possible diet is irrelevant. It is absolutely the best way to avoid these carbs, and the win in avoiding these carbs is unmatched in it's benefits by any other diet.
