The only way to know you have FH is by a genetic test. "High" levels of total or LDL cholesterol, even in the range of 300-400, do not indicate FH. ”Elevated levels of cholesterol in the blood do not constitute a disease in and of itself” (Cholesterol Clarity). Cholesterol must invade the artery wall to do damage. Statin drugs are not inevitable even if you have been diagnosed with FH by genetic test, there are nutritional adjustments in addition to a low carb diet that can be used.

Since cholesterol in food does not impact cholesterol in the blood (Myth #2 in link in my first post) and consuming saturated fat has nothing to do with heart disease (see the very latest meta-analysis that yet again has proved this in the research section http://forum.lowcarber.org/showthread.php?t=458979), you will find few Low carbers treating their "high cholesterol" with statins. As a man, statins may have some benefit if you already have heart disease, and that is likely through anti-inflammatory properties, not cholesterol lowering. Even the new AHA guidelines moved away from treating "a number".

If any of the lipid results have merit, it is the Trig/HDL ratio and the best way to improve that is to eat a diet with no sugar, no starch, no processed seed oils, and to add saturated fats and exercise......aka, the Atkins diet.
