Show Notes
No one is exempted from exposure to environmental pollutants. While this may sound worrying, there are steps, backed with scientific and empirical evidence, to rid our bodies of these harmful pollutants. However, there is still a lot of misinformation about detoxification that we need to uncover.
In this episode, Dr Bryan Walsh discusses the common perception about detoxification and explains the actual science behind it. He talks about the different phases of detoxification and its complexity. Dr Walsh also tackles the importance of excretion as a widely ignored aspect of detoxification in diets and weight loss programs. Detoxification may seem challenging to start, but it begins with getting to know your body and blood chemistry.

Episode Highlights [04:47] How Dr Walsh Started Studying Detoxification
- Dr Walsh was interested in health and fitness from a young age. He eventually ventured into massage therapy and became a fitness professional.
- He took a postgraduate degree to become a naturopathic physician.
- After his education, he felt that he had to study more to serve his patients better.
- His goal is to connect conventional Western medicine and alternative medicine.
- Dr Walsh cites some ridiculous notions surrounding detoxification. In the 80s, it used to be rehabilitation for addiction to alcohol and drugs until everybody started hopping on the 'detox bandwagon'.
- Xenobiotic or commonly known as 'toxins' is something foreign to the body that can cause damage in excess.
- When water leaves the body in any form, water-soluble toxins leave as well. Meanwhile, the body still needs to turn fat-soluble toxins into water-soluble toxins to get rid of it.
- Our bodies are naturally built to detoxify pollutants through biotransformation.
- Listen to the full episode for an in-depth discussion on toxins!
- First is heavy metals. This category includes aluminium, arsenic and mercury, among others.
- Second is persistent organic pollutants, which include phenol, dioxins and pesticides.
- The last category is volatile organic chemicals (VOCs) that are usually inhaled.
- In essence, pollutants are everywhere.
- While everyone is exposed to pollutants, the levels may vary due to location and lifestyle.
- For instance, Dr Walsh believes that athletes may be less toxic due to sweating during exercise.
- Listen to the full episode to know the body's pathways for getting rid of environmental pollutants.
- There are a lot of variables and testing methods to consider in assessing toxin exposure.
- The fat biopsy is regarded as the gold standard test. However, because different body areas store different amounts of fat, there's no consistency in the body.
- Taking these tests can guide you to make different lifestyle changes. However, keep in mind that they cannot determine your body's toxicity level quantitatively by an absolute number.
- Listen to the full episode to learn more about the complexity of detox questionnaires.
- Toxin gets stored in a cell or area with low concentration. This is called the concentration gradient.
- If there's more toxin in the blood and less in the cell, it will get stored in the cell.
- When fasting, you go into a catabolic state. Studies have shown that xenobiotics in the blood increase in this state.
- All detoxes are cellular detox.
- Phase 0 starts with the fat-soluble toxin entering the cell.
- Phase 1 is the reaction with the addition of a hydroxyl group.
- Phase 2 concerns conjugation reaction of adding methylation, sulphation and the like.
- Finally, phase 3 is when excretion happens.
- Tune in to the full episode for Dr Walsh's analogies and a detailed explanation of each phase!
- The keys of detoxification are mobilisation, biotransformation and excretion.
- Mobilisation is getting pollutants out of storage.
- Biotransformation encompasses phases 1 to 3.
- Excretion should take the toxin out of your body.
- Dr Walsh recommends doing a weight loss program in conjunction with a detoxification program.
- During periods of weight loss or catabolism, xenobiotic levels increase.
- The problem with rapid weight loss and yo-yo dieting is the redistribution of toxins in the body without excretion.
- Being nutrient sufficient is enough to support phase 1.
- Phase 2 is driven by amino acids.
- Phase 3 can be blocked by three inhibitors: milk thistle, curcumin and green tea. However, note that the effects of these three inhibitors are based on its dosage and the context.
- One protocol will not work for everyone; you have to look at the totality. Listen to the full episode for more details about nutrients and botanicals!
- For Dr Walsh, thyroid dysfunction may be secondary to another issue.
- Once symptoms show, you should consider if it is a protective reaction.
- Dr Walsh shares details about his detox course, including a practitioner-based programme and The Walsh Detox for the general public.
- Your blood chemistry is essential in determining your detoxification programme.
7 Powerful Quotes from This Episode
'I'll be the first to tell you that science will never prove some of the things in life that are the most important things — relationships and love and how we try to study how the brain works — and I don't think we have any idea'.
'This is part of my problem with the industry is we can't even decide on what a toxin is. . . So what I would suggest, the one that people are most talking about, that's why I think environmental pollutant or environmental toxins make more sense because usually what people are talking about are things that are outside of us that get inside of us and cause damage of some kind'.
'They will test their blood, their urine and their sweat for a specific xenobiotic or environmental pollutant. And they will find in many cases, it's not in the blood, it's not in the urine, but it is in the sweat'.
'Everybody's toxic. Everybody needs to detoxify. . . It's not necessarily exposure; it's we all have some degree of storage. The question is, when somebody is not feeling optimal, is it because of that or not? And so you can't run around screaming everybody's toxic because I don't know that they are'.
'And so it's [toxins are] concentration gradient-based, which also means so that's how it gets stored. If there's more in the blood and less in the cell, then it will tend to go into the cell. And that's when it gets stored'.
'There's some ridiculous stories out there that will say, 'The body won't release toxins if it's not healthy enough, and it doesn't think it can deal with them'. That's not true'.
'I'm against protocols; because one protocol will be brilliant for one and harmful for another same protocol'.

Full Transcript Of The Podcast!
Welcome to Pushing the Limits, the show that helps you reach your full potential with your host Lisa Tamati, brought to you by lisatamati.com.
Lisa Tamati: Hi, everyone, and welcome back to Pushing the Limits. And today I have just a super superstar for you, Dr. Brian Walsh, who's sitting in Maryland in the USA. Dr. Walsh is someone that I've followed for a long time and learned from. He is one of the great teachers in biochemistry and physiology. And today we are discussing detoxing very relevant to this time of the year. And this is all really next level information. Because it's all about detoxing, like what are the actual physiological steps of a detox process? And what is the latest and current research. This is not something you read in a two page magazine article detox type of thing. But this is the real deal with someone who really, really knows his stuff.
Now, Dr. Brian Walsh has been studying human physiology and nutrition for many, many years. And he spends his time sort of poring over the latest research and synthesizing all of that information for the layperson to be able to understand. And he also lectures at Western States University in biochemistry. And as a healthcare professional, he's a doctor of naturopathic medicine. And he has an online educational platform called metabolicfitnesspro.com, where he helps other health professionals like myself, and many, many others, as well as lay people with his programmes and courses.
And we're going to be discussing today, as I said, detoxing, how to do it properly, when not to do it, what to be aware of if you are doing it. And he's you know—Dr. Walsh is someone who's really known for challenging traditional dogma in health. And he actually goes and does all the research, does deep deep dives into all of the clinical studies into PubMed, and then brings us the latest and information. So he's really someone that you want to have on your radar, someone that you want to know, if you want the latest and greatest in information.
I hope you're enjoying your Christmas time, by the time this episode comes out, Christmas will have been passed. And we're into the new year. And hopefully the world is on a new trajectory and that 2021 is going to be a hell of a lot better. And what better way to start the year than with a discussion around detoxing and getting your body in good shape for the year ahead. So without further ado, I'll be heading over to Dr. Brian Walsh.

Of course our epigenetics programme is still open, if anyone wants to know and understand the genes—understanding everything to do with your genes, eliminating the trial and error for your body, understanding what foods to eat exactly, which areas you're predisposed to have problems with, how your brain functions, what your dominant hormones are all of this sort of great information. Please also reach out to us and we can put you in the right direction. We've done a few webinars already on our epigenetics programme. And in the coming weeks, we're also going to be having Dr. Ken McDonald on from PH-316, who's going to be going a little bit more deeper into this. So I hope you enjoy the session though for now with Dr. Brian Walsh. And we'll head over to him right now.
Lisa Tamati: Well, hi everyone and welcome back to the Pushing The Limits. This week, I am super excited. I'm jumping out of my skin. I have a man who I really, really admire. I love his work. He's got an incredible brain. Just absolutely mind-mind conversation we were going to have today. I have Dr. Bryan Walsh with me. Welcome to the show, Dr. Walsh.
Dr. Bryan Walsh: Thank you so much for being here.
Lisa: It's a really, really an honour to have you on. Dr. Walsh, you're still in Maryland, in the States? Can you give us a bit of a background just on who you are and sort of a quick synopsis and your background as a physician, etc.?
Dr. Bryan: Well, yes, I guess I should say it all started out, I was very much into health and fitness, even at a young age, quite honestly. I became a fitness professional—that's how I started. And then I did a lot of orthopaedic work, so that led me to massage therapy. So I did massage and I was a fitness professional. And the problem is my clients would ask me health advice. And here in the States—I'm a law-abiding citizen—I could have talked to them about nutrition and supplements, but I wasn't allowed to with those things that I did.
So then I looked—and there's something in the States, it's a naturopathic physician, naturopathic doctor. I know you guys have naturopathic there. They're a little bit different. It's a four year postgraduate degree. So you go to four years of university, and the traditional four years. And then you have your doctorate. That sounded really good to me because I was already into alternative health. I was devouring books, on health, on herbs, on homeopathy, everything in the health. And that was the umbrella for all these things that I was interested. And I thought, wow, that's great, perfect.
So I went through four years of that. Spent way too much money. But it's also where I met my wife. So that is money rally well spent. Yes. Although we both went to school there. So we doubled our debt, essentially, by marrying each other. But what we quickly realized is that it didn't really prepare us to do what we wanted to do. And it didn't take long. I was sitting in front of patients, and I honestly—I didn't think I know what I was doing. I didn't feel qualified. I spent all that money over the four years of school with great classes, but it sounded like all these great topics but...
And so that started me—and this is all to tell you this story— where I realized I had to teach myself everything, that I had to reteach myself physiology. I know we're going to talk about detox today. But how I stumbled upon that what I'll call is the truth about detox. And so where I am today is I believe in old medicine, I believe in the body heals itself. But Western science and Western medicine is incredible. I mean, we owe much of what we know about the human body, in terms of mechanisms and pathways and how herbs even work in the first place, to Western science.
So what I tried to do is bridge the best of both, is to take the alternative nutritional functional health world, which is great for some things but horrible in others, and combine that with conventional Western medicine, which is great in some things, but horrible in others, and I try to connect the two. So I hope that gives you much of...
Lisa: That's brilliant.
Dr. Bryan: I love science.
Lisa: And I love the way you sort of combine the traditional or the alternative with the allopathic sort of model because they do both have good things, and they do both have problems.
Dr. Bryan: Absolutely. And I can tell you, I love science. But I'll be the first to tell you that science will never prove some of the things in life—of the most important things, in relationships, in love, in health. We try to study how the brain works and I don't think we have any idea. We try to—we're doing genetic testing now, I don't think… We talked about the microbiome, I don't think we know much of anything when it comes to these things. So, science is fascinating. It's so fun. It can occupy you for hours upon hours upon hours of reading and the rabbit hole of PubMed, but I don't think it will ever offer some of the answers.
So that's kind of where I live is that we live in this expansive universe full of all sorts of possibilities. But here on Earth, science really helps us a lot understand certain things, but it doesn't contain all the answers.
Lisa: It's a very humble approach. And I think a really good place to start because we know a lot, we don't know a lot more. But we have to sort of work with what we've got and the best knowledge. And this is something that I've really enjoyed out of like, I think I've devoured everything I could find on the internet of yours. And I must say sometimes, I'm like my brain is spinning, trying to keep up and it's fantastic. And I was talking to a colleague who's also really into you and he's got a master's in physiology and he said, 'Well, I struggled, too, so don't feel bad'.
But you do have a way of putting things into analogies that I have just found absolutely fascinating. And today we're going to go into detoxing. And there is an analogy in this story that I've heard you speak of a couple of times that really went, 'Aha, I get it now'. So definitely want to delve into that analogy. But so just to start with, with detoxing. Let's look at what detoxing in the public realm—if you like—in the popular—the magazines. People talk about detoxing a lot. And I think that we don't understand what detoxing is. So let's start there. What is a proper detox?
Dr. Bryan: So what you just described, that's the problem. It's a mess. I was just in the checkout line at the grocery store, two days ago. I even took a picture of my phone to send my wife and it was like, 'A faster way to do a liver detox', and it was some medical doctor. I thought, 'I'm not even going to open that magazine. It's going to be garbage'.
You're right. People say, 'drink a little bit of lemon juice in the morning, and that's a great way to detoxify the body'. And then I was in the airport one day, and I saw these foot pads that you put on your feet to help pull toxins out of your feet. And then there's the foot pads, and there's colonics. And there's all these different things, and that's why conventional medicine doesn't believe any of this because you have these people saying, 'Well, when you skin brush, then you're detoxifying yourself', maybe, maybe not. But no wonder they think that we're a bunch of quacks because if you stand back and look at all that nonsense, it does look like quackery.
In the 80s, detox, the only detox there—unless you were like a hippie—in the 80s, was like a celebrity going through some kind of rehab for some kind of addiction, alcohol or drug addiction, then they would go through some kind of rehabilitation, so that was a detox. That was the only detox there was. And then all of a sudden everybody started getting on this detox bandwagon. And the thought is that we are bombarded with—we're basically these toxic waste cesspools of disgusting that's inside of our bodies, and the only way to get rid of it is to do these to detoxify.
Now, there's some truth to that, some truth. But our body is designed to—a better way to say detoxification is biotransformation, first of all. So there are two different types of we'll call—I don't even like the word toxins, quite honestly. You can call them xenobiotics, starting with it with an 'x'. Xenobiotic means it's something foreign to the body. You can also call them environmental pollutants, environmental toxins, whatever you're going to call it. Some people say synthetic, but that's not true because Mercury is toxic to the body in high amounts. So, for lack of better terms, we can call them toxins, xenobiotics or whatever. But they're things that are foreign to the body that in excess can cause damage.
There's essentially, for simplicity sake, two forms, there's water soluble, and there's fat soluble. Water soluble, by and large, I don't think we have to deal with too much, because our body is really good at getting rid of it. Our body is so much water already, we don't have to do anything to it. If we have access to something that's toxic, and it's water soluble, our body's pretty good at getting rid of it.
And when you look at the ways of getting rid of something, it's anywhere that water goes. So sweating, obviously, urinating, it's quite a bit of quite a water. In faeces, there's a small amount of water that gets expelled there. And even technically—and people have measured this but in tears or saliva, you can get rid of toxins too. So anything where water is leaving the body, then water soluble toxins are leaving as well. And I personally believe that those aren't much of a concern to us because our body... It's kind of like if you take a whole bunch of B vitamins. Technically, those can be toxic in high amounts but they're water soluble in your urine turns glow in the dark yellow if you take too much of that because your body is getting rid of it. Same with vitamin C or any of the water-soluble vitamins.
Interestingly—and I hadn't thought of this as a way of describing this, but the vitamins that they say to be careful with are the fat-soluble ones like vitamin A, D, and K because they can accumulate and then those are the toxic 'vitamins' if you look at conventional medicine. So fat soluble toxins, those ones are more of concern because they can get stored and the body has to work a little bit harder in order to get rid of them. In other words, you have to take something that's fat soluble, turn it into something that's water soluble, and then the body can get rid of it and all those pathways that we talked about.
So the body has built in detoxification or bio transformation processes—everybody says it's the liver but it's not. The enzymes and steps necessary for this are found in a number of tissues and in quite a bit. So, things that have exposure to the outside world, the skin has this disability, the liver does, the kidneys do, the lungs incidentally do, the testes in a guy does when we consider the location as exposure to the outside world more so than some of the internal organs. And we can go into the details of this but basically this fat-soluble toxin that can cause damage to the body gets metabolized or bio transformed, turned into a water-soluble toxin, if you will, a compound. And then is easily excretable in—again sweat, tears, saliva, urine, or a little bit in faeces. So yes, that's kind of a nutshell version of it, I think.
Lisa: Okay, so. So let's look quickly at what are toxins and what sort of a fix they have in the body? So we're talking things like your heavy metals, your Mercury's that you mentioned, your pesticides, your preservatives in your food, there's chemicals that were exposed to.
Dr. Bryan: So that's honestly—this is part of my problem with the industry is we can't even decide on what a toxin is because the toxin if you think about it, a toxin is something that could cause damage to the body. Right? So then you could say a reactive oxygen species or oxidative stress is a toxin, technically. Hormones, if you have too much of a hormone, can that cause damage to the body? It absolutely can. So, then all of a sudden is a hormone a toxin.
And so that's where we start to run into problems, is that we just throw out these terms like toxins. Well, what is that something that? Something that damages the body? Well, a hammer, if you hit me on the head is going to damage my body. Is that a toxin? Let's say, oh, it's internally. All right, well, so how about lipid polysaccharides from a gram-negative bacteria? That's an infection. Is that a toxin? Yes, it is. So that's our—aflatoxin, you have mould in your house. And so, it ends up being this really broad term that people have a hard time describing.
Now, so what I would suggest. The one that people are most talking about, that's why I think environmental pollutant, or environmental toxins, make more sense because usually what people are talking about are things that are outside of us that get inside of us and cause damage of some kind. And there's three, let's just say major categories of that there's actually more. One would be things off the periodic table. So that's the heavy metals, by and large, so aluminium, arsenic, mercury, all those types. Even copper, copper is toxic. Iron is toxic.
Then there's—loosely the category that you can call persistent organic pollutants. And that's all the ones that get all the press, like this phenol and phthalates and dioxins and all those different things, pesticides. And then there's the ones that you could call them volatile organic chemicals, or VOCs, those ones are usually inhaled. So, you paint, you're repainting your house, or your apartment and the smell that you get, or cosmetics or toiletries, cleaning products. If you buy a brand new piece of furniture and that off gassing, carpets. So those are the— mean, there's more, but those are the three major categories that I consider so... But then you consider where those come from, in the food that we eat, in the water that we drink, in the air that we breathe, it literally is everywhere.
Lisa: Yes. So we are toxic.
Dr. Bryan: Well, yes. We are. And I long time ago would say that we're all toxic, and everybody needs to detoxify. And I've tempered that a little bit because like for example, there's one published paper that suggests—well, okay, I should take a step back—everybody is exposed, everybody is exposed, period, end of story. To prove otherwise, I would need to see that proof.
Now, it's going to be different considerably, however, based on your location, where you live. In New Zealand versus America. Here in America, I'm in Maryland, but that's going to be a lot different. I'm near farmland. So, we might have exposure to pesticides, but not so much some of the other things that might have been more of an urban area. In New Zealand there's other different things.
So also that depends on one's lifestyle. So me and my family largely eat organic food as much as possible. We use—I don't say green cleaning products, but we use better cleaning products than just the standard things. And so we probably have less exposure than somebody following a standard diet using standard toiletries, cosmetics, yes, and all those different things too. So, we all have exposure. Yes, that's it. I think I believe that's irrefutable.
Is it stored in all of us? And I'm going to go ahead and say yes, but to different degrees. For example, you said you're a professional athlete. You have sweat a lot more than the majority of people. There's also some really interesting evidence showing that exercise actually upregulates certain detoxification or bio transformation enzymes. So you might actually be more adapted to that.
Lisa: Another good reason to do it.
Dr. Bryan: Absolutely. You know what? It's so funny, like, you know you're supposed to, but then you just see more and more reasons. And it does, it absolutely has been shown in papers, to upregulate certain detoxification enzymes. In addition to the fact that you're sweating more so than somebody who's sedentary. So, I haven't seen any literature on this, but I believe that most athletes are probably less toxic than the general public.
Lisa: The sweat is also a preferred pathway for some of the toxins to leave the body.
Dr. Bryan: If used badly, yes. The skin has been called the third kidney before, which is kind of a cute thing to call it. I mean, is it or is it not? I mean, it's not like you're urinating out of your skin. So that should be gross. Next time you sweat, think of that. No, but it's a major excretory organ.
And I will add this, there's some really interesting, really interesting scientific papers — small, unfortunately, not a lot of money in this industry to test this stuff. But they will take a group of people, and they will test their blood, their urine, and their sweat for a specific xenobiotic or environmental pollutant. And they will find in many cases, it's not in the blood, it's not in the urine, but it is in the sweat.
Lisa: Exactly. Yes. The preferred pathway, yes.
Dr. Bryan: That's an indication that a) it's being stored and b)... Yes, whether it's a preferred pathway or not, what that means to me is that it's probably stored in the tissues. Because you think about the blood, the blood is circulatory and it's bringing things around. The kidneys are filtering the blood. So, if it's not in the blood, that makes sense, it's not in the urine. What that means is it's stored. It's if it's not coming out in the urine, that means it's not in the blood, that means it's stored in tissues. And so, it isn't going out. So whether it's preferred by the body or not, I don't know. But that just means that it's right there, right close to the tissues.
Lisa: Yes, In coming out.
Dr. Bryan: Right close to the periphery, and it's coming out via the interstitial fluid and stuff surrounding itself. But here's another thing to consider, too, when you talked about the demographic of the population that listens to this is, while most athletes probably have less—I mean, when it gets a broad state, you can't say yes, might have less because of exercising, because of firing. But are they exposed to something more than might somebody else be?
So for example, if they're drinking out of plastic bottles that have been warmed up sitting in the sun all day, like might they have more excess pollutants...
Lisa: More BPA...
Dr. Bryan: ….these people are outside exercising in polluted area.
Lisa: Exhaust fumes.
Dr. Bryan: Exhaust fumes. I mean, you think about your respiratory rate when you're exercising, your respiratory rate is quite a bit higher than somebody who's sedentary. So then all of a sudden all those...
Lisa: And oxidative stress
Dr. Bryan: Yes, absolutely. So there's a lot of factors to consider for sure.
Lisa: Yes. So we've looked at—these are the broad categories of toxins. And yes, we're probably all toxic, and we need to be doing or thinking about doing a detox—I don't want to say protocol—but to thinking about it constantly detoxing. And you touched on the couple of studies here where they measure the sweat, they measure the urine, and so on, and they got different measurements for different things. That's one of the problems, isn't it? The assessment criteria. Because obviously, if we're doing a detox, we want to be able to assess, are we actually getting—and when you dived into the literature of assessments in defining out which is the best—how do I see if I'm toxic? What did you find in the literature around all the assessments?
Dr. Bryan: So in the functional medicine world, there's no shortage of—well just tests in general and really attractive, good looking tests that when you look at them, you want to run them. Like, 'Well, I would like to run this on myself. forget my patients or clients I want to run these tests'. The scientific validity on a lot of these tests is not there at all, despite what people might say or think.
Yes, so I'm not opposed to testing for toxins. But there's so many variables to consider, and the practitioners that are running them, I don't think are considering these. So I think a lot of people are using them—they're wasting their money on them because they're not considering all these variables. So, for example, the first question to ask is, 'what tissue do you test'? Do you test the blood? Do you test the urine? There are hair tests. Technically, in the literature, they test fingernails for toxin exposure. There's so many different ways of testing–fat biopsy, you want to take a needle into your fats, take some of it out and test that.
And actually—I'll say since I said that—fat biopsies are considered to be the gold standard for internal toxic burden, and that would make sense if that's where they're stored. But the problem is, according to research—and this is done on humans, mind you—that different fat depots in the body store differing amounts of things. So, you might inject it into your, your, your butt fat, and find a whole bunch of one thing, and then you do it to your abdominal fat, and you come up with a higher amount of something else. So, if that's the gold standard, and you can't even have any consistency in the human body, then that's not going to be accurate, either. And if that's the gold standard, then that's not accurate, then none of them are going to be accurate.
So, the short version is there are some—I guess I'll say, like validated as much as you can questionnaire—subjective questionnaires that one can take and get an idea of how toxic they may or may not be. Now, it's not quantitative. It's quantitative in the sense that you get a numerical value for the score. But it's not quantitative, in terms of like, This is how toxic I am. I am 80% toxic out of 100'. It's just a subjective questionnaire. But if somebody were to take a questionnaire like this, and scores high...
Lisa: We've got a problem
Dr. Bryan: ...and then does a few detox rounds or whatever, for a few months, six months, nine months, whatever it is, and then does it again and their scores are lower, that's good enough to suggest that they're doing better. And what's interesting about some of these questionnaires, is they not only asks things like, 'do you live around industry? Do you have exposure to petrol or to gas'? But your symptoms as well. And so it takes all of these considerations, like, 'Yes, I live and work around a lot of chemicals, but I don't have symptoms' versus somebody that has a whole bunch of symptoms that are associated with toxic exposure, but they don't live around them. So, it does—they really are comprehensive.
Lisa: I'd like to get a couple of the links to those if we could possibly see.
Dr. Bryan: And listen, it's free. That's the very nice thing. You don't have to spend 300 US dollars on some blood tests that may or not be accurate. And what people are really interested in is, 'how toxic are you'? Well, if my surroundings and my symptoms suggest that I am, based on these questionnaires, that's good enough for me. And as opposed to test, if you do it six months later, and it's approved, then I think you're probably doing a little bit better.
Lisa: It's a little bit like your cell blueprint, which I found brilliant, by the way, and if anyone wants to check out that we can put the links. That questionnaire that you've developed there gives the practitioner the direction to go and we don't have a specific, 'This isn't definitely but hey, you might want to check your thyroid. Hey, you might want to go and check if you've got a parasitic infection, or whatever the case may be'. And I find that a brilliant system really.
Dr. Bryan: But isn't that what a practitioner wants to do? I mean, the patients come in, and they want to know, 'Well, where should I head first'? And detox questionnaire—and again, so everybody is exposed period, everybody's exposed. Everybody has some degree of storage. Now, I don't know how much. They might be really toxic. They might be cut. Who knows? But everybody has some degree of storage. The question is, then, is, 'Are your symptoms—because of xenobiotic exposure—are in storage or not'?
And that's where these questionnaires come in handy. If you take a questionnaire like that, and I mean, because there's people out there, believe me, there's plenty of them. Everybody's toxic, everybody needs to detoxify. There's an old book called Detoxify or Die. I mean, if that's not scary enough. It's a good book, but I mean, it's not necessary. So we all have exposure, it's we all have some degree of storage. The question is, when somebody is not feeling optimal, Is it because of that or not?
And so you can't run around screaming 'everybody's toxic' because I don't know that they are. But if you score high on one of those questionnaires, then that's the direction you'd want to look into. And if you score low, I mean, listen, people will still argue it, 'Well. We're still all toxic'. I wouldn't go down that road. It wouldn't be the first thing that I'll thought about.
Lisa: It's not your first protocol
Dr. Bryan: Oh, no. The questionnaires... Absolutely.
Lisa: Yes, I think that's what I do as a practitioner too, as epigenetics practitioner, and a health coach, is go for the low hanging fruit first. Because we can go in 100 directions and I can confuse the hell out of my clients and they can be like, 'what the hell am I doing'? But if you are going for the ones late tackle, best piece of the puzzle, and then work your way up the food chain is so to speak—and actually find out which ones are the most important.
Dr. Walsh, I mean—we're going to put the links in the show notes—you've developed your own detox system if you like, which I'm really keen to share with everybody and for them to check out. But let's go in now to the actual four phases of detox: zero, one, two, and three, and you have four, isn't it? In most people—or some people are at least aware of phase one and two detox within the cell. And when I first heard you talk about this, I was like, 'Wow, okay, there's a zero and there's a three'. Okay, can you explain in a nutshell, what the body does when it gets a toxin? It's in the blood for some reason, it's gotten there. What actually happens next in these detox phases?
Dr. Bryan: All right, well just to make it really comprehensive. I'll tell you, when you said when it gets into the blood, what happens? So when it gets in the blood, it can be detoxified, biotransformed, and excreted. But the best way to describe this is, so if it's in the bloodstream, wish I have something to sort of model this with but so like, so the bloodstream, and then you have you have a cell next to the bloodstream. Now there's—in physiology, there's what's called a concentration gradient. And these membranes… And so let's say we have the bloodstream in a tube—I really wish I had some kind of props here. I'm looking around. I have—my son has a Santa hat, razor blade, I don't know, I don't have much around here. Anyhow, so you have the bloodstream and here you have a cell. Now, if there's more in the blood of this, whatever it is, and less in the cell, it will tend to go into the cell. And it's usually fat cells, because it's fat soluble, it will tend to go into adipocytes or fat cells.
And so it's concentration gradient based, which also means—so that's how it gets stored. If there's more in the blood and less in the cell, then it will tend to go into the cell. And that's when it gets stored. There's a really, really cool paper that discusses how adipocytes used to be considered to be just an energy repository, but then turned out to be an organ because they excrete over a hundred different things. But one of the additional roles they suggest is that it is this. It is to store toxins or xenobiotics, or things that could otherwise damage the body—they're fat soluble, which would make sense.
Now, if that's a concentration grid. Now let's say we're in a fasted state, and we haven't eaten anything and or exposure. If there's less in the blood, and more in the fat cell, then it will leak out. And it's based on a concentration grade, it's based on homeostasis. There's some ridiculous stories out there that will say, 'the body won't release toxins if it's not healthy enough, and it doesn't think it can deal with them'. That's not true. What I've seen is that it leaks out from a homeostasis for a concentration gradient if there's less than the blood and more in the cell. So we are constantly leaking this stuff into our blood, if it's stored. Now this gets amplified. And I talked about this in the course, during lipolysis. So in a fasted state, in a catabolic state—not even not even losing fat, but just in a catabolic state which we go through at night. So if you stop eating at 8pm and you're sleeping, you're in a catabolic state, for example.
If you're in a state of fasting, or lipolysis, then that's going to speed up mobilization. So now—and all the studies I've ever seen on mammals or humans show this. In a hypocaloric state, or fasted state levels of xenobiotics go up in your blood. And I'll say it again because that's huge. In a fasted state or a hypocaloric state, like dieting, then if there's stored xenobiotics, it will dump into the bloodstream, and those levels go up. And they always show that every single time because that's a state of lipolysis as a catabolic state.
So then now we're back in the blood. So whether it's at an immediate exposure, or it was just released, the rest of the story remains the same. So then what happens? And I should just say too, I mean, I get frustrated with pieces of the industry. There's some people that will say, 'Well, it's not a detox if it's not a cellular detox. If you don't detox yourself, then you're not'... This happens at the cellular level, as all detoxes is a cellular detox. So what I'm about to describe next is the cell.
So let's say we have that xenobiotic it's floating around in the blood, we either just had exposure, or it came out of a fat cell. So in one of the cells, like the
