I don't mind that people are interested in bodybuilding/fitness, but if it's positioned as a replacement for traditional nutritional science, that's not the main goal of nutritional science. And personally it's not my interest: I don't really care about bodybuilding/fitness, but I do care about minimizing my risk of serious health problems. It's not clear to me that the two goals even result in the same recommendations; it's quite possible that there are diets that are good for short/medium-term muscle building which are not good for, say, long-term organ health. At least, I would want to see scientific evidence one way or another.
