A few people genetically have it that low. They will never get heart disease. The rest it requires some form of diet and/or pharmacology.An LDL of 60 is almost impossible.
HDL to triglyceride ratio is basically an insulin resistance test, which is accounted for in Apo-B (triglycerides are carried by VLDL particles which all have Apo-B). The most accurate blood marker for cardiovascular disease is Apo-B, which is not commonly tested (you’d have to request it). A good surrogate marker is the non-HDL cholesterol. If you are insulin resistant, you will have high non-HDL cholesterol, thus high Apo-B.The most important number is the ratio of triglycerides to HDL, which is measured differently in the USA and Europe (LOL, like gasoline octane?). Using the USA figures (which mine are), the ideal is below 2, which I am barely at (it's usually a little lower).
