**What can modern medicine learn from Orthodox fasting without reducing an ancient ascetical practice to another health intervention?** In this episode of the *Orthodox Health Podcast*, Dr. Pete…
Pete PatitsasGuestMichael ChristianHostJohnHostAnd it's one of those where looking first at the anthro's diet, it'd be very easy to misinterpret the emphasis on plant foods and the fasting periods and think that, well, monks mostly eat plants, so plants have to be healthier and we should only eat that way all year round.
which also made the fasting and feasting distinction a lot more important.
And that's one of the biggest things I hope people take away from this conversation, that the Orthodox calendar doesn't just give us fasting, but rather fasting and feasting.
We talked about the joy you have on Pascha night, where it's not just, oh, I'm getting to eat my meat now, but rather participate in that life with Christ.
And that's the biggest thing that our asceticism gives us is a way of life.
So there are times when we're going to voluntarily abstain from foods that are otherwise perfectly good.
So it's hard for us to turn the fast simply into a nutritional hierarchy where these are the foods that we must give up because they're bad, but rather sometimes we give up something precisely because it
is good.
Absolutely.
We talked a lot about how the orientation is extremely important.
And we've said on the show before that the demons fast much better than any of us.
And they're not saints.
And that right there ties us back into last week's conversation about the hormesis and that voluntary hardship.
The value of that stressor isn't just based on what we're withholding or imposing and whether that's inherently good or bad, but rather the context, the dose, our capacity, and just that purpose, right? Because when we bring the ascetical life into it, our why, that purpose matters even more.
Hunger can produce physiological adaptations and periods of reduced intake can change our metabolic signaling.
But orthodox fasting isn't just a clever way to produce changes to our glucose regulation, our microbiome, or all of the other things that we can measure.
it's not a purpose.
Right, which is where I think that the Mount Athos piece of the conversation becomes especially interesting because you can't really separate what they're eating from all the other things that they're doing on top of it.
Right.
