That's an article by Taubes partially explaining how the consensus that fat makes you fat came about and why that was a departure from the mainstream up to that point, but, uh, you are aware that Taubes has been just about crucified for those opinions? The article you cite is itself a non-mainstream article, you can't cite it as an example that the mainstream scientists have "always known" this. No, in fact mainstream scientists all over the place have been insisting that Taubes and Atkins and everybody else claiming it's actually carbs are not just wrong but evil for saying so. If this shift is actually made (which is still not a done deal), it will in fact be a consensus shift, one where the evidence has been available for centuries that the consensus was wrong, but a consensus was manufactured anyhow.
