Well, I'd imagine that they're Arnold's words. Maybe it's just because I want them to be, but I would hypothesize that Arnold dictated most of it and Bill just typed it up and put it in better wording. I would agree that it is a moderate intake. I know I take in closer to 2 grams/lb, but I would definitely say that you should eat no less than .8 grams/lb. And, really, 1 gram/lb is freaking easy to get. For most people that's about 170-200 grams. Piece of cake. Couple cans of tuna, couple chicken boobs, a dozen egg whites and a scoop or two of protein powder. Hardly seems too exorbitant to me.
And, look at that, I've almost completely eliminated the supplement company from the equation. Look at that! High protein and no supplements needed, or moderate. Even with my 400-500 grams/day I only use 3 scoops of protein powder. I spend about $50 per month on powder. Hardly seems like a conspiracy to me.
