That means, when you push your body into a higher active state, it will result in a much longer-lasting (many hours) fat burning capacity overall.
There are a couple things wrong with that theory. First off, fat burns better than carbs, even as body fuel. Second off, recruiting your body's fat for energy is tht goal to begin with. In other words, you are burning last year's pizza instead of the gels you just consumed. Third off, you are not counting for the increased adrenaline and other metabolic hormones released in the fasted state as well as the extra hgh released, which not only helps preserve muscle mass but helps build it faster.
Personally, I have found that I have much more energy when fasted than after I have consumed carbs and I ride faster and climb harder when fasted. If you are correct, my body is lying to me...
