What's missing in this article is mention of actual scientific evidence. I can believe that traditional nutritional recommendations are on flimsy ground, but replacing them with new cargo-cult ideas isn't necessarily better. Do these newer recommendations have good science behind them? My lurker experiences in /r/fitness are quite mixed; they seem like nice people, but the specific diet plans are very heavy on anecdotal evidence, with people professing very high confidence in recommendations relative to how much evidence there is (if anything, it reminds me of alternative-medicine communities). They're also a bit too focused for my interests on bodybuilding/image/etc. rather than measurable health outcomes, e.g. reduction in heart-attack or diabetes risk rather than muscle definition.
