What if the missing piece to improving your metabolism, balancing your hormones, and restoring your energy has very little to do with what you're eating? What if the light you're exposed to, the timing of your meals, and the signals your body receives from its environment are just as important as the food on your plate? This week on Optimal Metabolism, I welcome fellow registered dietitian Ethan Okunas, also known as The Quantum Dietitian, for a fascinating conversation about circadian biology, mitochondrial function, and the environmental factors that influence our metabolic health. Ethan brings a unique perspective to nutrition, looking beyond calories and macronutrients to explore how our biological clocks, light exposure, and daily habits influence insulin sensitivity, cortisol, leptin, energy production, and our ability to maintain a healthy weight. We explore why someone can be doing everything "right" with their nutrition yet still struggle with stubborn weight gain, fatigue, blood sugar instability, and hormonal imbalances. We also dig into some lesser-known concepts in quantum biology and how understanding our body's natural rhythms may help us make more informed decisions about our health. If you've been frustrated by a lack of progress despite eating well and working hard to improve your health, this conversation will give you a whole new perspective on the signals your body needs to function optimally! WHAT WE DISCUSSED: Ethan's journey from traditional dietetics into circadian and quantum biology, and why he believes nutrition is only part of the metabolic health picture. Why two people can eat the exact same foods and experience very different metabolic responses. The connection between circadian rhythm disruption, insulin resistance, and weight-loss resistance. Why mitochondrial health is so important for energy production, metabolic flexibility, and overall wellness. How morning sunlight influences biological signaling and may affect cortisol, blood sugar, appetite, and nighttime sleep. The relationship between circadian rhythms, leptin signaling, hunger, and late-night cravings. Why eating the same meal in the morning versus late at night can produce different blood sugar and insulin responses. What "environmental mismatch" means and how modern lifestyles can interfere with our natural biological rhythms. What quantum biology actually means and how to distinguish established science from emerging theories. The concept of structured water and its proposed relationship with light and mitochondrial function Practical circadian strategies to prioritize when dealing with insulin resistance, stubborn weight gain, hormonal imbalances, and low energy.

Have you ever been told your lab results are perfectly normal, yet you're still struggling with exhaustion, brain fog, stubborn weight gain, digestive problems, or hormonal imbalances? You're not alone, and there may be important pieces of your health puzzle that haven't been explored. In this episode of Optimal Metabolism, I welcome Dr. Jim Chialtas, a Doctor of Acupuncture and Chinese Medicine, licensed acupuncturist, and advanced Functional Medicine practitioner with more than 20 years of clinical experience. Jim brings a unique perspective to chronic health challenges by combining Functional Medicine with Traditional Chinese Medicine to investigate underlying imbalances and better understand how the body's systems work together. We dive into the fascinating connections between thyroid health, the brain, gut function, nervous-system regulation, and metabolism. We discuss why conventional lab testing doesn't always provide the full picture, how nervous-system dysfunction may contribute to persistent symptoms, and why seemingly healthy habits like fasting, exercise, and dietary changes don't always produce the results we're hoping for. If you've been doing everything right but still aren't feeling your best, this conversation will encourage you to look beyond individual symptoms and better understand the interconnected nature of your health! WHAT WE DISCUSSED: Why conventional lab results can appear normal even when someone is experiencing significant symptoms. How two people with nearly identical symptoms can have completely different underlying health challenges. The connection between thyroid function, metabolism, fatigue, brain fog, and stubborn weight gain. How the sympathetic and parasympathetic nervous systems influence digestion, hormones, and overall well-being. What functional dysautonomia is and how nervous-system imbalance may contribute to chronic health problems. The surprising relationship between the brain, gut, and metabolic health. Why treating digestive symptoms alone may not address the underlying contributors to gut dysfunction. How fasting, low-carb diets, and intense exercise may not be appropriate for everyone, especially when the body is already under significant stress. What Traditional Chinese Medicine can contribute to understanding health patterns that may be overlooked by conventional approaches. How combining Eastern and Western approaches can offer a broader perspective on complex chronic health conditions. Why identifying underlying contributors to illness is different from simply managing symptoms. CONNECT WITH DR.

300 EPISODES! 🎉 After more than six years behind the microphone, I am so grateful to every one of you who has listened, shared an episode, learned alongside me, and supported the evolution of the Optimal Metabolism Podcast. I couldn't think of a more fascinating topic for this milestone episode! Today I'm joined by Ariana Thacker, founder of MoldCo, whose work in the mold space began after her own devastating experience with mold exposure. Ariana became extremely ill, was dismissed by eight different doctors, and ultimately discovered mold was at the root of what was happening to her health. This conversation also became very personal for me. I have long suspected mold could be an issue in my son's apartment. He has struggled with frequent illness, coughing and mucus, along with anxiety and nervous-system symptoms. MoldCo sent me one of their home testing kits, so we tested his apartment—and his results came back with a HERTSMI-2 score of 18, which MoldCo categorizes in its highest warning range and recommends further investigation and remediation. Ariana and I unpack what those results mean, why mold-related illness can be so difficult to recognize, symptoms you may never think to connect to your environment, and how mold exposure may intersect with inflammation, hormones, your immune system, nervous system, and metabolic health. If you've been doing "all the right things" but continue to struggle with unexplained symptoms, your environment may be another piece of the puzzle. WHAT WE DISCUSSED: Ariana's personal experience with mold exposure and being dismissed by eight different doctors How her own health crisis ultimately led her to create MoldCo Why mold exposure and water-damaged buildings can be overlooked when investigating chronic symptoms Common and surprising symptoms associated with mold exposure Why someone can feel chronically sick even when conventional testing continues to come back "normal" The connections between mold exposure, inflammation, hormones, the immune system and nervous system How environmental exposures may interfere with metabolic health Why certain people can be much more sensitive to mold than others My son's ongoing coughing, mucus, frequent illness, anxiety and nervous behavior—and why I finally tested his apartment What we discovered when his MoldCo home test returned a HERTSMI-2 score of 18 What HERTSMI-2 testing measures and how to interpret the results What to do when testing reveals elevated mold levels in your home or apartment Testing versus guessing: where to begin if you suspect mold Practical next steps for addressing both your environment and your health LINKS MENTIONED IN THIS EPISODE 🏠 MOLDCO Learn more about MoldCo, home mold testing, and their approach to identifying potential mold exposure: Explore MoldCo 💨 AIR OASIS AIR PURIFIERS After learning more about mold exposure—and seeing the results from my son's apartment—I decided to take another step toward improving the air quality in our homes.

What if one of the most overlooked tools for improving blood sugar has been sitting right in front of us all along? In this episode of Optimal Metabolism, I'm joined by Chris Reade, entrepreneur and author of Beating Diabetes, to talk about his personal journey with type 2 diabetes and the discoveries that changed the trajectory of his health. Chris shares how his diagnosis pushed him to dig into the research for himself—and why soluble fiber ultimately became such an important part of his approach. We unpack what soluble fiber actually does, how it can influence post-meal blood sugar and metabolic health, and practical ways to incorporate more of it into your everyday life. I also share how this conversation connects with the strategies I teach for improving insulin sensitivity and blood sugar regulation. If you've been diagnosed with insulin resistance, prediabetes, or type 2 diabetes—or you're simply trying to improve your metabolic health—this is an episode you won't want to miss. WHAT WE DISCUSSED Chris's type 2 diabetes diagnosis and what prompted him to take a deeper look at his health The changes he made to improve his blood sugar Why soluble fiber became such an important part of his approach How soluble fiber can affect digestion, satiety, and the post-meal glucose response Practical ways to increase soluble fiber in your diet How fiber can fit alongside other metabolic strategies such as meal timing and fasting Common mistakes people make when trying to improve their blood sugar Why improving metabolic health doesn't have to mean following an extreme or complicated plan Chris's advice for someone newly diagnosed with prediabetes or type 2 diabetes Why there is hope for people struggling with their metabolic health A SIMPLE WAY TO ADD MORE FIBER This conversation about soluble fiber also ties beautifully into one of the tools I personally use and recommend—the Feel Great System. The system pairs a pre-meal fiber drink, with a concentrated yerba mate tea, making it simple to incorporate metabolic support into your everyday routine. I'm especially excited about the new Balance Apple formula. It provides about 5 grams of fiber per serving and combines multiple fiber sources with apple polyphenols and apple cider vinegar. The formula is designed to support fullness, the gut microbiome, and a healthier post-meal glucose response. balance-appledistributor-guidee… Ready to learn more? 🍎 Get the Feel Great System WITH the new Balance Apple: Shop the Feel Great System + Balance Apple 🌿 Learn more about the Feel Great System: Explore the Feel Great System 🍏 Want Balance Apple only?

What if one of the biggest missing pieces in your metabolic health has nothing to do with your diet—and everything to do with the light you're exposed to every day? In this episode of Optimal Metabolism, I sit down with Roudy Nassif, founder of VivaRays and a leading educator in light, circadian health, and quantum biology. Roudy's passion for light began with his own search for answers after years of struggling with ADHD, depression, mood swings, and chronic exhaustion that no diet, doctor, or supplement seemed to fix. That journey ultimately led him to discover just how profoundly our exposure to light—and darkness—can influence our biology. We dive into the connection between your light environment and cortisol, blood sugar, sleep, energy, mood, and metabolic health. We also discuss why getting your nutrition "right" may not be enough if your circadian rhythm is working against you. If you've been struggling with fatigue, poor sleep, insulin resistance, weight loss resistance, or cortisol issues despite doing all the "right" things, this conversation may help you recognize a missing piece. WHAT WE DISCUSSED: Roudy's personal journey from ADHD, depression, mood swings, and chronic exhaustion to discovering circadian and light biology Why light may be one of the most overlooked pieces of metabolic health Can you eat a great diet and still struggle metabolically because of your light environment? How morning sunlight influences your circadian rhythm, cortisol, blood sugar, energy, and metabolism How spending our days indoors under artificial light may affect metabolic and hormonal health The relationship between light exposure, cortisol dysregulation, and chronic exhaustion Roudy's experience with ADHD and mood and how changing his light environment affected his health Why circadian health may be especially important for women in perimenopause and menopause Common mistakes we're making with artificial and blue light What makes blue-light-blocking glasses different—and when should you actually wear them?

What if we've been focusing on the wrong things when it comes to preventing heart disease? In this episode of Optimal Metabolism, I sit down with Daniel Trevor, heart attack survivor, citizen scientist, serial entrepreneur, and author of Unholy Trinity: How Carbs, Sugar & Oils Make Us Fat, Sick & Addicted and How to Escape Their Grip. Daniel's interest in cardiovascular and metabolic health became deeply personal after suffering a heart attack despite believing he was doing the right things for his health. That experience sent him deep into the research surrounding cholesterol, insulin resistance, blood sugar, type 2 diabetes, nutrition, and cardiovascular disease. And this conversation challenges a LOT of conventional thinking! We explore whether cholesterol alone gives us an accurate picture of cardiovascular risk, why metabolic dysfunction and insulin resistance deserve much more attention in the heart disease conversation, and which tests Daniel believes can provide a better picture of what's happening before a cardiovascular event occurs. We also get into statins, vegetable oils, low-fat diets, processed foods, obesity, prediabetes, and why our rates of metabolic disease have risen so dramatically. You don't have to agree with every perspective presented in this episode to benefit from asking better questions about your health. My hope is that this conversation encourages you to become more informed about your own metabolic health, understand your numbers, and have deeper conversations with your healthcare provider. WHAT WE DISCUSSED: Daniel's own heart attack and why it completely changed the direction of his life Why he began questioning conventional thinking surrounding cholesterol and heart disease Is high cholesterol always an accurate predictor of cardiovascular risk? The relationship between insulin resistance, type 2 diabetes, blood sugar, and heart disease Why prediabetes and insulin resistance can go undetected for years Which cardiovascular tests and markers Daniel believes deserve more attention The controversy surrounding statins and their relationship with blood sugar and type 2 diabetes What Daniel believes we've gotten wrong about vegetable oils and dietary fat Why he challenges conventional low-fat nutrition advice Processed foods, appetite, cravings, and our modern food environment What's really behind the dramatic rise in obesity and metabolic disease What the Blue Zones can—and can't—teach us about longevity Practical steps you can take to better understand your metabolic and cardiovascular health ABOUT DANIEL TREVOR Daniel Trevor is a citizen scientist, serial entrepreneur, heart attack survivor, and author of Unholy Trinity: How Carbs, Sugar & Oils Make Us Fat, Sick & Addicted and How to Escape Their Grip. Following his own heart attack, Daniel immersed himself in research surrounding cardiovascular disease and metabolic health.

What if obesity isn't simply about food? In one of the most powerful conversations I've ever had on the Optimal Metabolism podcast, I sit down with CrossFit coach, author, educator, and metabolic health advocate Athena Perez to explore the deeper roots of obesity, emotional eating, and lasting transformation. Athena's story begins long before she reached nearly 500 pounds. She shares how childhood trauma shaped her relationship with food, why lasting healing required far more than losing weight, and how addressing her emotional health became just as important as improving her physical health. We also take a fascinating deep dive into Athena's experience completing multiple 40-day fasts. She openly discusses why she chose such an extended fast, what happened to her body and mind throughout the process, how she approached refeeding afterward, and whether she believes prolonged fasting helped reset her metabolism. This episode isn't about promoting extreme fasting. It's about understanding the complex relationship between trauma, metabolism, behavior change, and healing. Whether you've struggled with weight, emotional eating, insulin resistance, or simply want to better understand the human side of obesity, I believe this conversation will stay with you long after it ends. In This Episode, We Discuss: Athena's journey from nearly 500 pounds to becoming a CrossFit coach and educator The connection between childhood trauma and lifelong struggles with obesity Why healing emotional wounds was just as important as changing nutrition habits The decision to complete a 40-day fast What happened physically, mentally, and emotionally during the fast Whether prolonged fasting can "reset" metabolism The often-overlooked importance of the refeeding process What Athena learned about true hunger versus emotional hunger Common misconceptions about obesity and larger-bodied athletes Why sustainable healing goes far beyond the number on the scale Connect with Athena Perez Website: https://www.athenamperez.com Instagram: @athenamperez Learn more about Scaled Nation Training and Athena's educational resources for coaches and healthcare professionals.

Could your gut be the missing piece behind your hormone imbalance, stubborn weight, fatigue, and blood sugar struggles? In this episode of Optimal Metabolism, I'm joined by returning guest Dr. Cassie Smith, licensed naturopathic physician, founder of Modern Endocrine, and author of the new book Fix Your Gut, Fix Your Hormones. Dr. Cassie explains why so many women spend years chasing hormone solutions without realizing that the health of their gut may be driving many of their symptoms. We discuss the fascinating relationship between gut health, estrogen metabolism, cortisol, insulin resistance, inflammation, and metabolic health, along with practical strategies you can begin implementing today. If you've been struggling with stubborn weight, digestive issues, hormone imbalance, fatigue, or simply feel like your body isn't responding the way it used to, this episode will help you understand why healing often starts in the gut.

Have you recently been told you have fatty liver or high cholesterol? If so, you're not alone, and the good news is there are practical steps you can take to improve your metabolic health. In this episode, I explain why these conditions are connected and why simply focusing on cholesterol numbers or liver enzymes doesn't tell the whole story. We'll explore the root causes behind fatty liver and high cholesterol, and I'll share natural, sustainable strategies you can begin using today. In this episode, you'll learn: Why fatty liver isn't simply caused by eating fat How insulin resistance can contribute to both fatty liver and high cholesterol The "overflowing sink" analogy that explains why addressing the root cause matters Why cholesterol isn't the enemy—and what your numbers may actually be telling you The important connection between your gut, liver, and metabolism Simple lifestyle habits that support healthy blood sugar, liver function, and heart health Why I recommend beginning with a daily metabolic support system that combines a high-potency tea and a fiber matrix to support healthy blood sugar, cravings, gut health, energy, and healthy cholesterol levels Whether you've recently received concerning lab results or you're looking for natural ways to improve your metabolic health, this episode will help you understand what's happening in your body—and what you can do about it. Your body isn't broken. It's responding to the signals it receives. When you improve those signals with consistent daily habits, you give your body the opportunity to heal and thrive.

Most people think fiber is simply about digestion. But fiber is one of the most powerful tools we have for supporting blood sugar regulation, cholesterol, gut health, appetite, and overall metabolic health. The surprising part? Not all fibers do the same job. In this episode, I explain why fiber diversity matters and how different soluble and insoluble fibers work together as a fiber matrix to support multiple systems throughout the body. We'll also discuss one of the biggest misconceptions on social media, that all "gums" are unhealthy, and review what the research actually says about ingredients like guar gum, gum arabic, beta-glucans, citrus pectin, and more. Whether you're working on insulin resistance, digestive health, cholesterol, or simply trying to understand nutrition on a deeper level, this episode will help you make more informed decisions about fiber. In This Episode Why fiber is about much more than digestion The difference between soluble fibers and why each one has a unique role How a fiber matrix supports blood sugar, cholesterol, gut health, and satiety The science behind guar gum, gum arabic, beta-glucans, locust bean gum, and citrus pectin Why some people experience bloating when increasing fiber The truth about the "gums are bad" debate How to evaluate nutrition claims using evidence instead of fear Interested in the Fiber Matrix?

One of the most significant changes in women's health has officially arrived. Polycystic Ovary Syndrome (PCOS) is now known as Polyendocrine Metabolic Ovarian Syndrome (PMOS)—a name that better reflects the true nature of this common condition. In this episode, I sit down with Cory Ruth, RDN, women's health and PMOS expert, to discuss why this historic name change was made and what it means for the millions of women living with the condition. We explore how the previous name often led to confusion by focusing on the ovaries, when the condition is fundamentally driven by complex endocrine and metabolic dysfunction. Cory explains why insulin resistance plays such a central role, why weight loss can feel so frustrating, how PMOS impacts fertility and long-term health, and what women can do to support their metabolism through nutrition and lifestyle. If you've ever struggled with stubborn weight, blood sugar instability, irregular cycles, infertility, or have been diagnosed with PMOS (formerly PCOS), this conversation will help you better understand what's happening inside your body—and why this new name represents an important step forward in women's healthcare. WHAT WE DISCUSSED: Why PCOS was officially renamed Polyendocrine Metabolic Ovarian Syndrome (PMOS) How insulin resistance drives many PMOS symptoms Why PMOS is much more than an ovarian condition The connection between metabolism, hormones, fertility, and overall health Why weight loss is often so challenging with PMOS Nutrition and lifestyle strategies to improve metabolic health Common myths surrounding PMOS Practical first steps women can take to better manage the condition FOR MORE FROM CORY RUTH, RDN: Website: www.thewomensdietitian.com Instagram: @thewomensdietitian Book: PCOS Is My Power LET'S CONNECT: Instagram: @shana.hussin.rdn Facebook: Fast To Heal With Shana Hussin Website: shanahussinwellness.com ⭐ 90-Day Metabolic Reset (Start Here!)

Have you ever wondered why some people seem to do everything "right"—eat nutritious foods, take quality supplements, exercise regularly, and prioritize sleep—yet still struggle with fatigue, inflammation, hormone imbalance, or stubborn metabolic issues? In this fascinating conversation, I sit down with Dan Stachofsky, founder of Essential Energy, to explore one of the most overlooked influences on our health: the environment we live in every day. Dan's journey into environmental health began after his daughter developed a chronic immune condition that didn't fully respond to conventional or functional medicine. His search for answers led him to investigate how light, electromagnetic fields (EMFs), and our modern environment influence cellular energy, nervous system regulation, and the body's ability to heal. If you've been working to improve your metabolism, reverse insulin resistance, heal adrenal dysfunction, or restore your energy but still feel stuck, this episode may help you discover a missing piece of the puzzle. WHAT WE DISCUSSED: Dan's personal journey from technology executive to environmental health advocate Why some people don't heal—even when they're following the "perfect" protocol The hidden impact of our modern environment on metabolism and overall health How light influences mitochondria, cellular energy, and recovery The relationship between EMFs, the nervous system, and chronic stress Why circadian health is foundational for hormone balance and healing How artificial light can affect sleep, cortisol, melatonin, and blood sugar regulation Practical ways to create a healthier home and work environment Simple changes you can make today to better support your body's natural healing processes ABOUT DAN STACHOFSKY Dan Stachofsky is the founder of Essential Energy. After years in the technology industry helping build digital infrastructure for companies like Microsoft and Amazon, his daughter's chronic illness led him on a search for answers beyond conventional medicine. Today, Dan works alongside integrative practitioners to help people understand how light, electromagnetic fields, and environmental stress can impact cellular function and long-term health.
