I've eaten a full/normal fat diet for over three quarters of a century, and after being diagnosed as T2 just upped the quantity slightly to compensate for the reduction in carby fuel when eating LCHF. It's never done me
or my cholesterol levels any harm.
Very often the fat in a low carb high(er) fat diet is just a matter of replacing low/reduced fat foods with their natural full fat equivalents, so it's simply high(er) in comparison. (And I see absolutely no sense in taking something like dairy produce which is naturally high in fats and believing it's necessary to cut out that nutritious fat and then often replace it with added carbs to make it palatable again.
