Low carb down under has released a number of new videos from a recent conference. A number of doctors presenting I had not heard of before. Here is one on cholesterol that is really good. The first half of it is a good basic description of the mechanics of what cholesterol is and does and the second half how it relates to heart disease.

The Low Carb Down Under organization I give a lot of credit to my reversal of diabetes and weight loss. I watched a bunch of their videos four and a half years ago and learned of many of the doctors I follow today through those presentations.
