Dive down the rabbit hole of your unique health profile with functional labs that reveal what centralized medicine ignores.
Symptoms are signals that something's breaking down. When your check engine light comes on, do you investigate immediately or hope it goes away? Most people wait, then get standard blood work that says "everything's normal"—yet nothing improves. Functional testing reveals what those panels miss. Verify, don't guess.

Functional Diagnostic Nutrition is the framework I use to solve health cases—from straightforward optimization to complex chronic issues. Whether you're a Bitcoiner doing "everything right" but still struggling with sleep, skin, or anxiety, or someone stuck in endless trial-and-error without results, verification reveals what's actually broken.
Test, don't guess. Functional labs uncover dysfunction in hormones, immune function, digestion, detoxification, and energy production. I correlate lab findings with your specific health picture—not just treating numbers, but understanding what YOUR body is signaling. Standard panels miss this entirely.
Truth lives at the intersection of data and your lived experience. Both matter. Neither alone is enough.
Most practitioners don't have the time, training, or incentive to spend hours analyzing lab results, health histories, and research to build protocols tailored to your unique biology. That's where health detectives come in. I uncover the hidden stressors—hormone dysregulation, methylation bottlenecks, immune dysfunction, detox pathway congestion—that standard medicine ignores. These are the root causes driving your symptoms. Fix those, everything else improves.
Standard medicine: "take this for that." Functional testing: find WHY systems break down. This is why fixing root causes transforms health while symptom relief fails. Carnivore works until it doesn't? Diet alone can't fix hormone dysfunction, detox congestion, or methylation bottlenecks. You need to look upstream.

Standard medicine: "take this for that." Functional testing: find WHY systems break down. This is why fixing root causes transforms health while symptom relief fails. Carnivore works until it doesn't? Diet alone can't fix hormone dysfunction, detox congestion, or methylation bottlenecks. You need to look upstream.
My focus is restoring function in your body's fundamental systems—not diagnosing disease or managing symptoms. Across thousands of FDN cases globally, practitioners observe conditions simply resolving as health and normal function return. I investigate what's actually causing dysfunction: lifestyle factors, environmental stressors, hidden toxin burdens, and the specific weak links compromising YOUR body's healing capacity. Standard blood panels don't reveal these. Functional labs do.
My protocols address what your body actually needs for balance: nutrition tailored to your metabolism, circadian optimization, exercise appropriate to your current capacity, stress reduction (including the hidden stressors only labs reveal), and supplementation based on YOUR verified deficiencies—not what "works for everyone." When these align, dramatic improvements occur.

My own path to health sovereignty taught me the difference between guessing and knowing. I've wasted money on protocols that failed, run tests that revealed nothing, and learned which investigations actually move the needle. This experience lets me meet you where you are—frustrated by what's not working—and help you get the data that shows what's actually broken.
My training as a Functional Diagnostic Nutrition Practitioner gives me the tools to teach you everything I know about building optimal health. You don't just get protocols—you learn the framework for life. Walk away understanding your unique biology, how to verify what's working, and how to maintain sovereignty over your health long-term, maybe your family's too.
No shortcuts: I order the labs centralized medicine skips, analyze patterns they miss, and connect upstream dysfunction to your symptoms. I'm also your accountability partner when the protocol gets tough..
But if you're not ready to put in effort—if you want a pill to fix everything while changing nothing—you won't get results. Ask yourself: do I take ownership of my health now through self-custody and verification, or wait until I'm forced into the medical model of drugs and surgery? There's only one path to sovereignty. I'm here for those ready to walk it.
Between centralized medicine's pills and procedures, and alternative practitioners still chasing symptoms, stands Sleuth Wellness. We fill the gap where "sickcare" stops treating signals and starts investigating what's actually broken upstream—verified through functional labs, not guesswork.
Most people come to me after wasting money on protocols that didn't work. They guessed at gut issues, tried carnivore for hormones, supplemented blindly for sleep—nothing stuck because they never verified what was actually broken.
The five core functional labs I recommend reveal the upstream dysfunction standard panels miss:
Stress & Hormone Panel - Your HPA axis controls everything. Cortisol dysregulation shows up as insomnia, anxiety, stubborn weight, low libido. This test shows if you're running on fumes.
Organic Acids Test - Metabolic snapshot revealing mitochondrial function, neurotransmitter status, and gut dysfunction markers. Shows what's working at the cellular level.
Intestinal Permeability - Leaky gut compromises digestion and immunity. If your gut barrier is broken, everything else breaks down.
Pathogen Screen - Parasites, bacteria, fungi. You'd be surprised how many people walk around with infections causing IBS, fatigue, brain fog, and autoimmune flares.
Food Sensitivity Panel - When gut integrity fails, undigested food particles trigger immune response. That healthy chicken or avocado becomes a chronic inflammatory trigger every time you eat it.
Could you run just one or two? Sure. But you'd be guessing which dysfunction matters most. These five together show the complete picture—how stress affects hormones, how gut dysfunction triggers inflammation, how pathogens drain energy. It's a system. Verify it all, fix the root causes, everything else improves.
Hi. My name is George Capetanos, Certified Functional Diagnostic Nutrition Practitioner.
I know. That's quite a mouthful. I am best described as a "health detective." I use functional lab tests and lifestyle hacks to help parents struggling to balance career and family transform their health by shedding the extra pounds, restoring their positive mood and youthful energy, so they can become the engaged mentors their children deserve. Although my clients are primarily "older" parents, like me, I am here to help anyone wishing to end their cycle of trial and error, and regain optimal health.
In my youth, even through college, I was always the skinny, fun-loving guy open to challenges, motivated to explore new projects and disciplines. I was “lights on.”
That said, even in high school, I would succumb to bouts of tonsillitis, the flu or some other infection and they would take me out for the better part of a week, sometimes two. This happened at least once a year for as long as I can remember, some years as often as three.
I never thought much of it at the time. Kids get sick. I would take the antibiotics and get better. As I got older, the infections were fewer and further between, maybe less severe, but they were still there. And, if it wasn’t something more major, at the very least, I would get a couple of colds per year.
Still, when I would go to the doctor for a physical, I got the thumbs up. “You’re healthy,” they would say. So, I believed them. I WANTED to believe them. To those in my life who would say, “You’re sick all the time,” I put up the hand; if I really had anything to worry about, surely a doctor would have told me a long time ago. Never mind that my tonsils were practically the size of walnuts even when I wasn’t “sick.”
My dietary choices were usually less than optimal. I am half Greek, half Italian. Those cuisines always figured prominently on the dinner table, and this meant a lot of pasta and bread. Cookies and pastries were always an option as well. I rarely ate a lunch that wasn’t served between two pieces of bread. Since I wasn’t a great eater as a child, ALMOST ANYTHING I would eat was vehemently encouraged, regardless of its nutritional value. So, of course I gravitated toward the sandwiches, the macaroni, the pizza, the cakes and cookies.
By college, it was anything and everything… and beer, because that’s what you do in college. As my 30s approached, I developed seborrhea which brought scaly patches of skin to my scalp and elsewhere, the weight started to pile on around my mid-section and I developed the lumpy look most men present for the rest of their lives. But I was always the skinny kid and part of me was happy to have outgrown that stigma. After a while, though, I didn’t like what I saw in the mirror any more, so I tried the conventional wisdom: eat less meat and fat, stay mostly vegetarian but eat fish. Of course, it didn’t really work, and since I wasn’t considered overweight by doctors, much less the population at large, weight never became much of an obsession.
As the years progressed toward my 40s, I found it more and more difficult to find motivation. Projects presented would seem more like work, and less like an exciting opportunity. Somewhere along the line, I morphed from the “Yes. I can!” guy, into the “How am I ever going to do that?” guy. Increasingly, I would find myself living with a constant anxiety and irritability, often for no particular reason. I suppose I always lived with an underlying feeling of anxiousness, even as a kid. I just thought it was normal, but the feeling was getting more pronounced with each passing year and with it came more anger and frustration I couldn’t always explain. In fact, it took me years to even realize this was a main health complaint of mine. Feelings have nothing to do with health, I thought.
Around the same period, my mother had two serious battles with advanced diverticulitis requiring partial bowel removal and a blood transfusion due to surgical complications that almost killed her. This was the point at which I began delving into all the alternative health literature I could get my hands on. I wanted to help my mom and prevent myself from ever getting that sick in my own life. Several years after my mother’s ordeal, my father was diagnosed with prostate cancer. I hit the books again and found a world of alternative cancer treatments and nutritional healing protocols I was anxious to share with him.
A disciplined, former Marine Corps officer, my dad was more compliant than most with many of the recommendations I found. He never did any of the conventional interventions of chemo and surgery and is still alive to tell about well into his 80s, and years after his cancer diagnosis. Well, this success story ignited a passion in me for natural health.
I began adding the prevailing alternative health wisdom of the time to my own regimen and saw some improvement but it was usually short lived. This supplement or that herb would work a little, but not very well or for very long. Eating whole wheat instead of white did nothing to abate my increasing skin issues or give me more energy. I cut out red meat and switched to salmon. After a while, I learned farm raised salmon wasn’t a healthy choice anymore and other fish was riddled with contamination be it heavy metals or radioactivity. So, where do I get my omegas? Ah, a pill. Oh, and turmeric is good for inflammation. But, wait. Too much turmeric is bad? One thing was for sure though, I’ll stop drinking beer and switch exclusively to red wine because of its antioxidant benefits.
After a few years of futile guess work, taking this for that, and trying to find the best one-size-fits all diet, I just gave up. If nothing really seemed to work, why live by any restrictions at all? By this point, I was a foodie, a glutton for the gourmet, anything and everything was on the menu now. Red wine figured more prominently than ever, but so did good whiskey. Pleasure usurped health completely for many years as I threw up my hands and “just enjoyed life.” Well, of course, anxiety and irritability increased, symptoms of heartburn became frequent, although if you asked me, I didn’t think it was all that often.
After a while, the chest pains started which sent me to a cardiologist, but all her tests showed normal. In time, it became clear that acid reflux was at the heart of my problem. I drank more water which helped, but only a little, and my heartburn worsened which started affecting my already limited sleep schedule. The GI Doctor’s answer was to band-aid the problem indefinitely with pills, but I knew he wasn’t looking at the underlying cause of my GERD. I went up a couple of waist sizes and another doctor said I had “pre-diabetic” blood sugar levels.
I was a father now, but not all that much fun to be around and, truthfully, fun got harder and harder to have. My job had become drudgery and a death sentence. Years of TV production hours left me with little sleep, little satisfaction and no time or desire to exercise. My seborrhea spread to new areas and flare-ups were more frequent. I tried to avoid “bad” food but it was all around me, all the time.
I was 51 already, with a 6-year-old son, an “older dad”, and wondered how I was going to be a good father when I had no energy and a decidedly negative outlook on the future. Something had to give. When I’d return home after a long day at work, the cutest little boy ever would gleefully charge me as if Santa Claus himself walked through the door. Sure, I smiled and laughed, but inside I felt a profound sadness.
The truth was, I didn’t want to play with him. What was wrong with me? Why did I snap at him when he got too rough, knocked something over or left his toys in the doorway? All he wanted to do, after hours of waiting for me to get home, was play, but I felt too tired, too cranky, too consumed with my own BS from work, or some other convenient excuse I’d invent to let myself off the hook, to participate in his unbridled joy. Something had to give!
I recalled the time I was doing research into natural healing for my parents and remembered how passionate and alive I felt sharing these concepts and seeing the success that they could bring. It took a few more years to break out of my funk enough to dive into a certification, but I needed to find one that wasn’t going to be the same old blanket wisdom and this-for-that approach that dominates the alternative health field.
When I discovered FDN, it was like I’d found a rare pearl. I was hooked immediately by its emphasis on restoring the body’s FUNCTION instead of focusing on its symptoms and diseases. And the real kicker, it was verifiable through lab testing. I learned that the reason nothing I tried really worked was because everyone is different. There is no one perfect diet for everyone. One man’s food, truly is another man’s poison.
Once I learned and applied the concepts of the Metabolic Typing Diet taught in my certification training, it was as if someone had pulled back the curtain to reveal Oz. Within a couple of weeks of identifying my metabolic type and refining the proper fuel mixture for me, I shed almost every ounce of body fat. My mood improved, in a matter of days! I was floored. And this was only the leading edge of the magic sword that transformed my health.
As I delved deeper into my situation with functional lab tests, this detective work divulged hormone imbalances that disrupted my sleep cycle, tanked my energy, and pointed to malabsorption; I wasn’t properly breaking down the foods I consumed. Further sleuthing uncovered that “Leaky Gut” was a major factor in this poor digestive performance and also contributed to my heartburn symptoms. I was able to identify the three different critters that were wreaking havoc on my system and sharing my meals with me. These culprits figured large in the “Metabolic Chaos” my body was under, which meant a significant imbalance of good and bad bacteria. Add to that already complicated scenario, a multitude of food sensitivities that added to the list of hidden stressors I couldn’t feel or see.
Talk about “Ah, Ha!” moments.
So, I began the work of rebuilding my health. I avoided the foods I was sensitive to, eradicated parasites, bacteria and fungi using all-natural protocols, took supplements that supported gut rebuilding, proper absorption and detoxification, and made adequate sleep and appropriate exercise a priority. I hydrated, sought structural realignment with a chiropractor, spent time in the sauna sweating out toxins, and continued eating for my own unique biological requirements. And I still do it to this day.
I look at my life ahead as new man. In my mid-50s, I have never felt healthier or had more energy from the moment I wake until bedtime. I am nearly my high school weight and I can’t remember my body ever looking this good. I handle stress better than ever and regained my positive outlook. And, best of all, my wife and son like me a WHOLE lot better now.
Another great feature of my health restoration is that I don’t get sick anymore. I can be around a film set full of sickies and feel like Teflon. This is a new and wonderful reincarnation for me.
What is truly remarkable is that regaining my health no longer seems like work at all. It is a passion. I know my efforts will be worth it instead of hoping against hope that they will work. Now, when I neglect an area of my wellbeing, be it diet, rest, exercise, etc., I feel it immediately and know exactly why and what to do to correct it. No more trial and error. If I am presented with a new health challenge, I can test rather than guess, and begin the detective work anew.
All of these successes in my own life make sharing this knowledge with my clients a distinct pleasure. It is like the old adage goes: Give a man a fish, feed him for a day. Teach a man to fish, feed him for a lifetime. I see this career as a calling. There are few things more satisfying in life than being a health detective for my clients, to help them through their struggles and guide them toward their triumphs in self-care.
FDN is a gift and I want to share it with as much of the world as will listen.
A few years back, I did experience a major health set-back when I had a workplace environmental exposure to carbon monoxide and airborne particulates. I left work with flu-like symptoms and thought, how could I possibly get sick when I am doing everything right?! I thought I had left those days behind.
The red projectile vomiting I experienced on the drive home had me very worried and by the following afternoon I could not stand on my own or even get to the car to have my wife drive me to emergency. The EMTs were called and I took my first ever ambulance ride to the hospital. Once there, they found I had internal bleeding and suspected an ulcer. My hemoglobin had dropped so much, I required a blood transfusion.
The next day, I had an endoscopy where they examined my esophagus with a tiny camera to find a lesion that had opened up from the vomiting. Fortunately, it had already healed. However, the pictures revealed severe erosion of my esophagus, Class C on a scale of A to D! I was gob smacked. Apparently, the whiskey drinking I partook in and the heartburn I’d experienced before my health transformation had taken a much heavier toll on my body than I could have ever imagined.
I reached out to my colleagues in the Association of Functional Diagnostic Nutrition Professionals (AFDNP) and, as always, received a wealth of knowledge and experience, this time on the topic of esophageal healing. Through proper supplement additions and my continued priority on health building, I was able to heal ALL the damage done by my former self! I am proud to report that a recent follow-up endoscopy showed a 100% reversal of the erosion! Thanks, FDN. Another success story for the books.
