This sounds like hooey to me. I mean, fasting may trigger some survival/distress mode mechanisms, but do such triggers actually consist better health? All other things being equal, to the the extent that you can experimentally make all the other things equal in this case, would I have a higher overall white blood cell count after fasting than I had before fasting? Does fasting (starving?) weaken my immune system initially? To what extent? Is that extent recovered, and exceeded, by the new WBC production that wouldn't have been triggered otherwise? I'm comparing this, admittedly based on zero evidence, with the flight response. Adrenaline makes me run faster, but it doesn't make me a faster runner. That's how I mean when I say this sounds like hooey. Of course, I could be totally wrong, and I really have no basis to make this claim in the first place.
