What do you think of the idea that high glycemic index carbohydrates, such as starches, improve insulin sensitivity, simply by increasing insulin and its use... and does this also help replenish glycogen stores in the liver? I feel that fructose harms my liver, even if I eat a diet rich in fructose (starch) and low fat I can't sleep straight and rest, but if I only consume starch and low fat, I sleep uninterruptedly (liver full of glucose )
