In a 2000 calorie diet, 7-9 servings summed over fruits, vegetables, and grains vs. 6-7 servings summed over protein and dairy. 3-4 servings of protein where a serving is 1 egg or 3 ounces of meat means eating a meatless 2-egg breakfast and maybe a single hamburger patty at lunch and that's pretty much your daily protein.
Hardly some carnivorous revolution.
Suffice to say, I don't think any American actually followed the old guidelines, and I doubt any will follow this one either.
