Look at the rise at 6:15 thats got to be a liver dump telling the body to get ready were getting up. My measurement approximates it to 6.6mg. Insulin kicks in and he goes just below 60 and the liver compensates again for baseline. He eats the meal and etc medically these individuals are living in a state of hypoglycemia but they feel fine. The upper line is akin to diabetes but they are not confusing ?
