Oy! Doesn't anybody read their own profession's medical literature? The standard lab number for LDL is not a genuine measurement, but a calculation (look up the terms "LDL" and "Friedwald equation" together in a web search engine). Moreover, the calculation tells you *nothing* about the composition of the LDL. On a ketogenic diet, it's not unusual to see a rise in the level of the "Type A" particles -- large and fluffy, which some studies indicate have a protective effect on the CV system. The "Type B" particles, small and dense, are the one implicated in CV disease, and their levels almost always go down on a ketogenic diet.
