The whole point of Variability is that we have a hard time predicting outcomes from interventions because of the simple fact we are complex adaptive organisms. We cannot predict how someone will react to increasing/decreasing calories or macronutrients. However, if we increase the variability of the system, it increases our bandwidth to adapt to interventions and increasing the likely hood of success.
From a scientific perspective, is the idea of variability of systems (endocrine, cardiovascular, immune, nervous) the best way to increase the likelihood of success from any change to diet and/or lifestyle?
I think variability as a whole is a good strategy in increasing the likelihood of success. If we’re increasing variability, we’re building a robustness that previously wasn’t present. The ability to tolerate different stressors is a big factor in success. I like the HR example you use a lot. If my RHR is 70/80 bpm and my max is 190, there’s not a lot of bandwidth to work in there. But if I’m 50bpm resting, there’s a lot more bandwidth to work with. We could even look at the interplay between the systems. High RHR probably has a low HRV leading to a reduced tolerance to handle stress, reduced immune function, inability to recover from a nervous system standpoint. If we can improve the variability of these systems, the way they interact with each other is likely going to be better as well.

That was the hope from that module, if we have these markers in a better spot can we handle more stress? Lowered HRV or Elevated RHR would mean we are stressed in some way and we are not as capable of handing stress in a meaningful way. Alternatively if those metrics are better we can handle stress more effectively, so that would lead to increased variability.
