None of your posts are kind, well-intentioned or supported. You keep resorting to the same old recipe:
1. insult
1b. saying someone lacks insight
2. and then a very terse statement or no statement at all, like your post, that just simply states some fact, without your own words to explain or paraphrase anything, along with some non-specific link.
If someone was truly ignorant and you were kind-hearted, you would at least meet them half way and provide SOME explanations of things. Why should 30% be a good amount of calories to have from protein for an athlete? What is both the theoretical idea supporting this (human biochemistry) as well as empirical scientific data and research? I am not, as jerkoffs in other threads say nonsensically, demanding that you answer such questions conclusively and exhaustively and unreasonably. But if you were kind, you would at least elaborate on your own thoughts on the matter...
But I'll start (these studies admittedly do not cover research correlating protein intake and athletic training or performance, but that does not mean they are not relevant)

The reason I cite these studies--not all of which are related directly to an exclusive independent variable of protein intake--is that, I, too, was once like you. I believed the more protein, the better. I read books by athletes, and general textbook advice from nutritionists and yada yada. I never asked about what the Scientific literature and evidence was for this, or even what the deeper theoretical explanations were for this. When I came across studies like the ones I have mentioned, they made me question my existing beliefs.
