How does fasting affect aging?

When you talk about cryotherapy, heat therapy, when you talk about peptides, stem cells, they are replicating. What this last thing does, which is fasting. Fasting increases cell detoxification, decreases your body's stress with toxins, improves your efficiency of your cells. If you have dysfunctional cells and dysfunctional mitochondria, they actually self heal and repair during fasting. These other things I just mentioned are trying to replicate what fasting does. And so that's one of the reasons why you'll see elite athletes, other people doing water fasts, doing fasting, mimicking diets, other things like that, different brain trauma experts, whether it's Dr. Brenson or Dr. Wahls or the Wahls protocol, they'll have some kind of interval fasting that is basically doing the same kind of thing. It's affecting senescent cells or dysfunctional cells that are inflammatory. It's removing dysfunctional older cells. It's improving the function of your cells. It's making your mitochondria regenerate themselves.
