You don't even need to get into the science to dislike this article. And I'm not trying to argue against low-carb... I feel better on low-carb diets myself. But this article lays out a couple scientific facts, while shaming the reader into unquestioning agreement by saying, "This is X 101". But then lists a pseudo-scientific premise tied to their third "fact", and tries again to shame the reader into agreement. This is simply a manipulative writing style, and we should be ignoring it, not discussing it.
