VERY INTERESTING post! Since I was diagnosed as a type 1.5 diabetic, and had to eat low carb even on the bike, I started ordering an iced coffee at the rest stop on my long rides and feel great. Now I know why it works. I agree with the posters that say triglycerides in the blood during cycling is a GOOD things, at least for those of us who ride to burn excess body fat, or need to burn a higher ratio of fat than glucose for fuel for whatever reason.
