My conclusion (and this is only my opinion) is that one could equally make the case that a carbohydrate-laden diet has negative effects on cholesterol and I think that, on balance, a ketogenic-type diet is more healthy than a carbohydrate-heavy one. Interestingly, there isn't so much controversy about whether ketogenic diets work or not (it's widely accepted that they do); it's mostly about how they work and whether that is good/bad/indifferent from a health perspective.
