I can honestly say that this past weekend I experienced something entirely new. The "brain fog" was gone. Completely. I never even knew I had brain fog. It really helped that you broke down the metabolic carbohydrate cycle and explained it so I could understand. Love the fat burning chart. I finally see how to lose weight and why I was not successful. I was eating way too many carbs. Not sugar necessarily, but tortillas, wheat bread, brown rice, hummus and other beans.
