Thank you so much for having me.
podcast-host
extended water-only fasts up to 10 days, and I've looked at the before and after.
podcast-host
Frankly, the fasting has been one of the most incredible unlocks that I have found.
podcast-host
The before and after, looking at glucose control, oral glucose tolerance tests, hemoglobin A1c, etc.
podcast-host
All these things that really do matter for the long term, for mental health, for physical health,
podcast-host
have had dramatic, dramatic shifts.
podcast-host
And I've talked about that before.

But the sad truth, the truth about fasting is that it can be really hard.
podcast-host
And that is why Walter is interesting.
podcast-host
He's best known for something called the fasting mimicking diet, FMD, which is essentially a way of eating that produces many of the benefits of fasting,
podcast-host
while still allowing you to eat food.
podcast-host
So if we look at that a little more closely, he took what he learned in these randomized control trials and so on and packaged it into a five-day program called Prolon, P-R-O-L-O-N.
podcast-host
It's five days.
podcast-host
So for five days, you restrict your food a bit.
podcast-host
And what Prolon does is makes it idiot-proof.
podcast-host
Comes in one box.
podcast-host
Everything is laid out.
podcast-host
There's no guesswork.
podcast-host
You just follow the packages.
podcast-host
And in scientific studies, five-day cycles of the fasting mimicking diet, improved markers tied to metabolic health and aging, help people drop fat while holding onto lean muscle, and even associated with measurable drops in biological age.
