Episode Date: May 2, 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.  What we discuss:  The importance of fiber in diet (95% of Americans don't get enough) Why fiber should be prioritized over protein for better nutrient absorption Biohacks for reversing biological age Kris's 10-day Vipassana silent meditation retreat experience How Kris reduced his biological age to 26 years old EMF mitigation practices EBO2 blood filtration therapy for removing toxins Perspective on NAD supplementation (preferring trickle dosing over IV Thank you to our sponsor: Therasage: Head over to therasage.com and use code Be Bold for 15% off  TruNiagen: Head over to truniagen.com and use code HUSTLE20 to get $20 off any purchase over $100.

Hi guys, it's Tony Robbins. You're listening to Habits and Hustle. Crush it! Today on Fitness Friday, we have fitness expert Chris Gethin, and he reveals why fiber, not protein, is the nutrient 95% of Americans are missing. He also shares how he hacked his biological age down to 26 using peptides, hyperbaric oxygen, and a 10-day silent meditation. 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 8 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 wanna 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 Biome, which is this like a fiber supplement, right? Which, you know, 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.

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 hot dogs, for instance. 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. You know, that should always be a priority. Not first, not your protein, because if you're taking in, if, let's say you're cleaning out your, 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. 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, like 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? Okay, I wanted to ask you about basically reversing your biological age because you said you talk a lot about that at these conferences. 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 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.

Yeah, no, no, talk about all that. You don't have to talk about like, I want you to talk about like things that you've seen scientifically or through your, the lens of your world that actually do reverse the biological age. It could be any biohack, it could be whatever. I want things that in your opinion actually reverse your biological age. Okay. All right. So we were talking about injectables earlier.

So epitalon, the peptide epitalon, some of your listeners may have heard of that. Taking that a couple of times a year will help with the prevention of the shortening of your telomeres. That has been shown. So epitalon twice a year. And then of course, as people out there do metformin, metformin could be a good alternative unless they can get that, unless they're taking like a dihydro berberine, for instance. Metformin could be a good alternative unless they're taking like dihydroberberine, for instance. Metformin is going to be a little stronger. Rapamycin. By the way, oh, I was going to ask you about that. Okay, continue. Rapamycin. Yeah. So, rapamycin, taking five grams of that per week. So, you basically

take five tablets, five tablets once a week of rapamycin. That's another thing. How does that work? I saw that on some, wasn't it, Brian Johnson was saying that. And it was like, isn't it kind of, there's not enough, there's not enough like data on that. Can it be dangerous or? I don't think it can be dangerous, but yeah, it is fringe. There's no doubt about it. You know, I know he does gene therapy as well. I wouldn't say it's as dangerous as the potential of gene therapy. That's a lot more invasive. True.

Hyperbaric oxygen, we've shown that really helps with the recuperation and the healing of all of our organs. So I'd say hyperbaric oxygen, if you can throw that in there. The one thing that I'd say, I've been able to reduce my biological age every year since 2014, it was exceeding my chronological age. And I've reduced it now to 26 years old. And I honestly believe the biggest thing out of all these things that I've just given a shotgun approach to has been sleep because I wasn't sleeping before. I was sleeping a few hours a night. I had mold toxicity that I didn't know about, but got that cured.

And, uh, the other thing was just being a lot more, like I said, looking at things in equanimity. So I did a 10 day Vipassana silent retreat where you are, you know, you can't make eye contact, you know, you don't take anything in to read, you certainly don't have your phone, it's just, you don't make eye contact with anybody else, you're meditating from six o'clock in the morning till eight o'clock in the evening, you have two breaks.

You know, on the fifth day, most people leave because it is so difficult, because your thoughts are coming into your head, you know, all the stresses from the past, all the worries about the future. 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, you know, and of course you can measure your biological age with telomeres, methylation, the whole vac 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 hack 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. 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 can't buy that. Right. That was what I was going to say. 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. So how long were the breaks? In this, if every day, how long did you get for a break? So you had 30 minutes in the morning at around, I think it was like 10 o'clock, 10 30, then it 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 S N Gouenka is the person who, who started the Vipassana retreats. He's based out of India. He's passed away now, but that's carried on and 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 light or 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 mountain tops. 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 reclamycin? Do you take it? Yes, once a week. Once a week.

And do you take this epitalin peptide to shorten your telomeres? Twice a year. Twice a year. So you do all of these things, hyperbaric. Have you tried gene therapy? No, I haven't tried gene therapy. I'm not willing to do that just yet. Yeah.

I've done EBO2. I don't know if you've done EBO2. I don't know if you know what EBO2 is. I think Darshan may do it at his clinic. I've done it in London a couple of times where it completely cleans your blood. It'll separate your plasma from the blood. So it'll get rid of like mycotoxins, microplastics, any toxicity that you'll have in your blood. So you've actually got an IV in your left arm,

IV in your right arm. It takes about 19 minutes, I believe, to completely filter your entire body. And you actually can see in a vat what comes out. If, for instance, that you've got, obviously, a lot of toxicity buildup, you see it there. Luckily, when I did it, it wasn't that bad, as my friend, Tim Gray,

who puts on the health optimization summer. When he did it, I was like, okay, that's pretty bad. But luckily mine wasn't as bad, but he lives in London. I live in Boise, you know, maybe that's something to do with it. Wow. So did you feel after you got that done? Did you feel different? Did you feel more? I don't know. Did you feel healthier? Did you feel cleaner? Did you feel less brain fog? That's what I was going to say. Less brain fog and I was able to sleep better. The quality of my sleep increased. Obviously, a lot of us measure our sleep and I noticed that my sleep got better and I had

better brain clarity. Kind of like, not like a new tropic, but somebody had just kind of brushed out all the cobwebs in my brain. And so is that dangerous? No, I don't believe so, because you 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, okay. How expensive is it? Um, I believe it cost about 1,500 pounds so I'd say probably be about $1,800 Wow, how often should people get that done? Like I guess it'll 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 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 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's like saying at the end of the week Okay, I want you to eat your week's worth of protein. Well, your body's to only gonna assimilate so much Not only that we know that NAD can Feed cancer can not not will it can like if you've got a genetic

Disposition for a cancer or maybe it runs in your family, you shouldn't do high dose NAD. So I always suggest like a trickle dose. For instance, you know, you could take it orally, you could inject it subcutaneously, like two days on, one day on, one day on, one day off, whatever it may be. If you're traveling and you're under a lot more stress, maybe you're going to take it every day. I believe that's the more efficacious way of doing it.

I get the majority of my clients to just take the oral format of convenience.
