Professor Volek has finally been picked up by the media in a proper manner; he has been referenced before, but this article in the mainstream Telegraph is quite good by media standards for LCHF coverage. I featured his earlier study in the Cholesterol Conundrum seminar, as it was an excellent illustration of the biochemical reality re human management of Saturated Fat - but this latest one is a great design, and very provocative

In short, all risk factors improved in the High Sat Fat, versus the High Carb Diet. The only current caveat is that while practically all people improve everything across the board, a minority of people have an increase in their ApoB particle count. The solution to this is simple - favor Monounsaturated Fat energy in diet. Also, note that Volek et al included 5 indivduals who went in the counter-current direction, moving from high to low carb, and they saw the opposite effect - thus showing that the increasing carb specifically was driving the negative results.
However, the Jury is decidedly out on whether high ApoB in the context of an ultra-healthy Low Insulin regime is even clinically relevant - no-one has explored this scenario. This is the $1M question, and the data suggests not a problem (including some evidence from Quebec Cardio Study). Remember that High Carb generally drives everything into the bad place (including ApoB count), and is a primary root cause of the tragedy unfolding in today's world: Heart Disease, Obesity, Type2 Diabetes, "Type3" Diabetes (Alzheimers), and all the other afflictions of modernity. As you would expect in an evolved organism, a bad nutrition factor is deleterious across the board. Roll on the emergence of correct Science in the coming decade.
Sat fat ideal fuel, but only in presence of moderate/low carbohydrate - otherwise you might as well be eating Poly !
