What I've noticed is that most docs who are using the dietary approach to lipid/glucose issues are ones that got frustrated with the "standard" answers while trying to solve their own issues. They then branched out on themselves and then started applying what they observed to their patients. This goes back to Dr. Atkins, who had a weight/lipid problem himself and used an approach published in a 1963? JAMA paper. It worked, so he started trying it on his patients. Also Dr. Richard Bernstein, who as a T1 diabetic and engineer, was one of the first to use a portable glucometer. He learned to use his diet to keep tight serum glucose control (his target being 83 md/dL before and after meals). He tried to write about his approach in the '70's but was rejected since he wasn't an MD. This prompted him to go to medical school starting at age 45 (no small feat to get accepted). He's been treating patients since finishing training and continues to be very active today at near age 80. He even has a monthly teleseminars/webcasts where he answers emailed questions. http://www.diabetes-book.com/
