Just remember that we are not all alike. Each of us processes food differently. What works for one may not work for us. If you really want to know how your body works, you have to experiement. I would be very reluctant to eat 7000 calories a day even if it was all fat because I have always managed to extract every single calorie and nutrient in any food that I eat. This WOE may give me an small "advantage" but mostly I am eating fewer calories and that is why I am losing.
