A while back I blogged a two-parter on LDL Cholesterol (Part 1 / Part 2). Part 1 deals with how unreliable standard blood tests are for determining your real risk. In part 2, I highlighted real world examples from the offices of doctor William Davis. And now, I'm going to show you a real world example from a reader and (obviously) fellow high-fat Paleo eater. Click here to access Patrik's NMR LipoProfile (Nmrlipo PDF) He kindly gave permission to share it with you.
