You may be putting the cart before the horse there. Cholesterol is a complex subject, and mainstream wisdom is under threat [1]. The lipid hypothesis holds that cholesterol promotes heart disease, but cholesterol could also be something the body uses to combat atherosclerosis caused by infection say.

Regarding LDL elevation on keto diets, this is true but not necessarily a reason to abandon the diet [2]. I recall listening to a podcast interview with keto researcher Dominic D'Agostino (I can't find it anymore) in which he expressed the following opinion on this: so many biomarkers improve on these diets, so if LDL gets elevated don't sweat it, because cholesterol is so poorly understood anyway.
