There's a huge difference between trying to avoid the latest fad and stick to whole foods, and trying to maximize saturated fat intake (especially animal saturated fats). Talk about a fad (and a poorly backed one, scientifically speaking).
Sure, if you consider over a million years of evolution eating a large amount of saturated fat a fad. As for science, gimme a break -- is this the same science that has been a proponent of a low fat diet for the last several decades? The same science that points to cholesterol and saturated fat being harmful yet at the same time pointing to polyunsaturated garbage vegetable and seed oils as healthy?
