Fri, 02 May 2025
While everyone seems obsessed with protein intake, could the true secret to better health be something most Americans are ignoring? In this Fitness Friday episode, I talk with Kris Gethin about the importance of fiber and why we all need it. We also dive into longevity hacks like how Gethin reduced his biological age to 26 years old, why a 10-day silent meditation retreat was his most challenging but effective longevity practice, and the benefits of peptides like epitalon for telomere health. Kris Gethin, a renowned transformation expert and entrepreneur, has revolutionized the fitness industry with his no-nonsense, results-driven approach to bodybuilding and coaching. As the founder of Unmatched Supps and former CEO of Kaged Muscle, he has established himself as a pioneering force in the supplement industry while developing the innovative DTP (Dramatic Transformation Principle) training method.

Chapter 1: What is the importance of fiber in our diet?
He is the founder of Unmatched Supplement and the Dramatic Transformation Principle. Chris delivers powerful longevity hacks that go way beyond supplements. So let's dive in. Before we jump into today's interview, a quick word from our sponsor, BioMe. Did you know 95% of us aren't getting enough fiber?
That's a big deal because fiber is key to our gut health, digestion, energy, and even our weight management. And that's why I'm excited to share BioMe's daily prebiotic fiber with you. It has eight grams of fiber per serving, plus prebiotics to support your gut. It's an easy and tasty way to close that fiber gap in your diet. You can mix it into smoothies or yogurt.
There's flavors like chocolate or unflavored versions. It's both simple and enjoyable. And I love how easy it is to fit into your busy routine. And it's perfect for when you travel as well, which is why I always take it with me in my bag. If you want to make fiber a part of your daily routine, and I suggest you do, head to bio.me and use code Jennifer20 for 20% off your first order.
That's B-I-O dot M-E and code Jennifer20 for 20% off. Now let's dive into today's episode. I just did a podcast yesterday about this because one of the girls who was on my podcast, besides doing a lot of other things, she founded this company called Bione, which is this fiber supplement, right?
She sent me a bunch of it because I didn't realize that she said that 95% of Americans are not getting enough fiber in their diet.
Yeah, correct.
And it's such an important macronutrient. I find it interesting because right now it's super trendy to talk about protein and people are not talking about fiber. But fiber is so important to your diet plan.

Chapter 2: Why is fiber prioritized over protein?
Yeah, yeah, 100%. Americans in particular focus, like you said, so much on protein. Now, that's not always clean protein. It could be like, you know, hot dogs, for instance. You know, it's going to be some sort of processed protein or burgers. But the thing is, when you're having protein, now that ferments in your gut, in your colon, and that can cause issues.
That's why it is essential to have fiber to ensure that you're cleaning this out constantly. So fiber should always come first. That's why I have clients eat that first from their plate. You know, ensure that you're, you know, getting the rainbow, for instance. But not everybody wants to eat vegetables. Okay, then you supplement with fiber. That's going to be the next best thing.
Much like a lot of people are deficient in, let's say, magnesium, nearly everybody is deficient in fiber. That should always be a priority, not first, not your protein. Because if you're taking in, let's say you're cleaning out your colon. then of course your body is going to absorb so much more of that protein anyway.
So you don't have to have such a huge amount of protein just to be satisfied for, let's say, muscle gaining purposes. It's what you absorb that matters, not what you take in. And you'll absorb so much more when you have more fiber in your diet.
Yeah. Um, that's why I'm glad that you mentioned that because we don't hear that every day. We hear a lot about protein. We kind of, it's like, this is the, this is the world we live in, right? It's all about social media and people, you know, glom onto something and that becomes the Bible and then forget about everything else. Right. Um, okay.
I wanted to ask you about, uh, basically reversing your biological age. Cause you said you talk a lot about that at these, these conferences and, So I know what you're going to say already. I mean, sleep, incredibly important, right? Eating enough fiber, obviously. Exercising. What are some ways we can reverse?
What's like the best ways we can, besides what I just said, we can reverse our biological age?
Yeah, so there's a few things. If we're going to be talking about what we can do in everyday life, I like to try to look at things in equanimity. So I'm not trying to be so judgmental or reactory. That's one thing. Number two, put down the phone more. Bookend your day.
Don't use it for a good hour in the morning and don't use it for an hour before bed because you're constantly releasing dopamine all the time. And with that dopamine, a lot of the time comes cortisol. And that cortisol is a hormone that can lead to heart disease, stress, and then that will shorten our lifespan. And of course, there's other things that we can talk about as well.

Chapter 3: How can we reverse our biological age?
But if you really stick it out, That was probably the hardest thing that I ever had to do. But then after a while, all these emotions just come above and you look at everything in perfect equanimity where you're not judging yourself or anybody else. And you're able to really lower your stress levels.
And obviously, you know, you're looking at everything in a much calmer state and you're in a parasympathetic state. I really think that has been the biggest impact that in sleep for reducing my biological age. And of course, you can measure your biological age with telomeres, methylation, the Horvath cloth, glycans, whatever.
What I would suggest is that you measure it and then measure it every year to ensure that you're able to bring it down.
That's amazing. So you basically went on this 10-day silent retreat, and that's the biggest half, really, for your age.
I believe. I believe. I'll earth every day. I have EMF-mitigating devices. I had Brian Hoyer come to my house from Shielded Healing. to ensure that there wasn't any dirty electricity in the house. You know, I have one of those Defender Shield fanny packs or phone cases on me at all times. So there are certain hacks that I do as well as that, but I think those were the two biggest.
You know, you can't buy that.
Right, you can't. That was what I was going to say. Like, you had to do the actual hard work of doing it. That wasn't for sale, because that's hard to do.
Very, very difficult. Like I said, the majority of people don't stick it out.

Chapter 4: What biohacks does Kris Gethin recommend?
So how many, how long were the breaks? Like in this, if every day, how long did you get for a break?
So you had a 30 minutes in the morning, uh, around, I think it was like, uh, 10 o'clock, 10 30. Then there was another one about one o'clock for an hour. And then you'd have another one in the evening, about six o'clock for about 30 minutes for 30 minutes. So what time did they make you start the six o'clock in the morning and you finish at eight o'clock in the evening?
So what are you doing when you're doing these? Basically, when you're doing these 14 hour meditations a day with only a couple breaks, where are you doing it? Are you on a mountaintop? Are you in a room by yourself? Like, where are you?
Yeah. So they have them all around the world, but I did it in Idaho, which was about a five hour drive from here. And yeah, you're in the middle of nowhere, but you're actually in a hall. You have a place where obviously you stay and then you walk about five minutes to the actual hall where everybody is within this hall in meditation. You'll have a guided meditation to begin with.
So SN Goenka is the person who started the Vipassana retreats. He's based out of India. He's passed away now, but that's carried on. It's just grown and grown and grown. So you start off with the guided meditation, but then you go into your own silence. And you know, that's the most difficult thing because you have no distraction.
We're so used to some type of distraction, whether it be noise, whether it be lights or, you know, interaction or reading, answering, et cetera. So it's very difficult to be alone with your own thoughts, but I think it's absolutely essential. particularly in the environment that we live in today.
Like I remember when I came out, when I drove back, I noticed everything that I didn't notice on the way there. I'm looking at the clouds, the mountaintops. When I was walking to and from the hall, the last few days, now I'm hearing the wind. I'm noticing the grass. Just different things like that that you just never notice and you take for granted.
But I remember having to stop in a gas station and just hearing the music and people in there. It took a long time to kind of get back to civilization because, you know, we're just so used to the artificial lights. We're so used to the noise and the distraction, especially with our phones today. that I think it's just releasing too much cortisol and too much dopamine.
Totally agree. Are you on this reprimicin? Do you take it?

Chapter 7: How does EMF mitigation impact health?
Chapter 8: What should we know about NAD supplementation?
No, I don't believe so because you're still, you know, you've still got your healthy, you know, your blood cells, your plasma put back in, you know, so I don't believe it is. It's just cleaning out all the toxicity.
Does it hurt?
No, it's absolutely fine. It's like giving blood, you know, I try to give blood every three months as well.
Wow. How expensive is it?
I believe it cost about £1,500. So I'd say probably about $1,800. Wow.
How often should people get that done? Like, how long does it last?
I guess it all depends on your lifestyle and where you live. Like, if you live a real clean lifestyle, I can't imagine you'd need to do it any more than, you know, once every three or four years. But if you live more of an unhealthy lifestyle or if you're in an environment that is potentially toxic, then probably every year.
Wow. What's your take on NAD IVs?
So I'm not into NAD IVs, and I'll tell you why. I prefer like a trickle dose. So I will take an oral of a product called NAD Regen. It doesn't just have NAD3 in it, but it has like resveratrol. It has spermidine. It has vitamin C. It's got a lot of different things in there that helps. Niacinamide. But...
