Cholesterol is a red herring. It is a terrible marker of cardiovascular disease, only somewhat applicable on a standard high carb diet, but there doesn't seem to be any correlation between health and cholesterol whatsoever. The real health marker everybody agrees on are triglycerides, and those tend to go down pretty quickly on a high fat diet (which often surprises people that underestimate how complicated metabolism is, thinking dietary fat = fat in the arteries)

In any case, in my experience, cholesterol drops slightly, triglycerides drops to very healthy levels quickly, HDL raises slightly in the normal range. Also, blood pressure and pulse rate drop in a week.
