Want to Clean Up Cellular Garbage? Train Fasted! Fasted Training Boosts Cellular Housekeeping (=Autophagy) & Forms the Basis of Structural Adaptations to Exercise
Want to promote muscular and overall health? Do this after an 8h+ fast. Exercise is a stressor. It modifies the intra and extracellular millieu, impairs the energetic status and stretches, sometimes even over-stretches the membranes. That certainly sounds as if you want to avoid it at all costs, but as nature had it, it is this eustress (good stress) that is absolutely essential for the remodeling of the muscle we are all working out for to happen - no stress no reason to adapt. It's that simple and does still have one major caveat: Too much stress and the adaptation turns into a constant and often insufficient repair process. But who wants to "deconstruct" muscle, anyway? Now, from the gymbro perspective the most important aspect of the training induced adaptation processes would probably be protein synthesis. And while you can actually argue that this was the case if things were just about "growing", a different picture emerges, when you look at healt...
