James' experience is that total cholesterol remained about the same (5.1 to 5.2), but the "good" stuff went from 1.9 to 2.6 and the "bad" stuff from 3.2 to 2.4, so he now has more "good" cholesterol than "bad". His triglyceride/HDL ratio is 0.19, when less than 2 is considered good. This is all on a low carb diet (probably under 50g per day), combined with moderate fat. We neither try to eat lots of fat, nor do we avoid it. Our fats include olive oil, butter, cheese, eggs, oily fish, nuts, occasional fat from meat.
