You are welcome.
The body does not rapidly burn fats, the fats are not very soluble. So your energy level is low when you are burning fats.
Plus, you have to train your internal organs to get ready to pull those fats out of your fat cells and turn the fats into energy. That is why I was suggesting the multi-hour training sessions. If you never exhaust your stored sugars in your muscles or blood stream, you do not train the rest of your body to extract those stored fats for use. That is why when I am building up my endurance in late winter or early spring, I am not ingesting any carbs shortly before or during the ride. Or if I have any carbs, they are minimal. I want my body to function well without a scheduled stream of carbs, so I train that way.
