That's one plausible explanation, so you think that my body continues to digest into the next day and that's what keeps my energy low?
I've had a lot of personal experience in fasting and cycling while fasting and only eating during a short window after a ride. Like you I always had great energy until I ate. That is except for one time when I bonked hard about 35 miles into a ride after having fasted more than 24 hours. I just think when you burn up all the glycogen stores in the muscle, it takes a while to build it back up, especially if you consume low glycemic foods when you do break the fast. I think digestion can cause low energy, just depending on how much you eat and how quickly that type food digests. I would suppose your low energy is more about building back stores of energy and possibly even repairing and rebuilding tissue.
