That looks like a much healthier guideline for eating then the South Beach or Atkins meat only diet. There's a nice book from Harvard University titled '
Eat, Drink, Be Healthy' that discusses the no-carb diets, and carbs in general.
The long and short is to avoid fatty foods, and refined sugars. Use whole wheat pasta, whole wheat bread, brown rice, etc. The reason to avoid the refined sugars is because they cause a very rapid sugar spike, which causes the body to start storing the extra food (as fat) by releaseing insulin. When the sugar level in the blood drops quickly because all of the extra insulin, you get hungry, and want to eat again.
After reading that book, I stopped eating all of the white rice that comes with a chinese restaurant meal and noticed I wasn't hungry in an hour. I found that amazing!
