Is Elevated Levels of Insulin The Cause of Disease?

"The hypothesis I currently find most compelling is that chronically elevated levels of insulin - rather than excessive calorie consumption or lack of exercise - is at the heart of the most pervasive chronic diseases afflicting our society: obesity, heart disease, cancer and even Alzheimer’s disease. 

I believe the key to peak performance and what I call "chronic health" is to reduce the secretion of insulin so you can run your body on your own fat stores." - Dr. Petter Attia, M.D.
