I started doing complexes about three weeks ago. It was just sort of a toss off at the time, so I didn't log it at the time. I started doing them regularly first thing in the morning, fasted complexees, and have noticed a couple things. The first is fairly typical: fat loss. These things are working better than anything else I've tried: extra weight work, fasted cardio (long fasted cardio), and Tabata stuff. The other thing I've noticed is less visibly noticeable but very interesting and the heart of my question. My energy (vitality, alertness, whatever you want to call it) is much better throughout the day. I'm not getting tired like I used to in the afternoon and it feels like I'm recovering better from my weight workouts. So here is my question: what might be the physiologic mechanism behind this increase in energy?
I have a few options. These options comes from memories of articles I've read in the past or possibly conjecture on my part, but I'm looking for something more definitive. One option is that the oxygen debt of complexes stimulates the production of more insulin receptors. The other option is that somehow the complexes stimulate the growth of more mitochondria. The bottom line is i have more and better energy throughout the day, I'm pretty sure it's from doing the complexes, and I'm wondering what the physiologic mechanism is behind the improvement. Thoughts?
