The Primal Shift

It’s dinnertime. You’ve cooked up a tasty meal and the whole family gathers around the table, only for your child to declare, “I’m not hungry!” Sound familiar? In this episode of the Primal Shift Podcast, we’re taking on one of the trickiest aspects of parenting: navigating those moments when your kids refuse to eat, either out of genuine lack of hunger or just a desire for something else (like dessert). We’ll talk about why rigid mealtimes might clash with our kids’ natural hunger signals, why forcing them to “clean their plate” can backfire, and how hormones like ghrelin and leptin play a key role in deciding when to eat (or not eat). We’ll also dive into the difference between real hunger and a fleeting craving — because if you’re not truly hungry, how do you know when you’re actually full? This episode will give you practical ways to handle dinnertime standoffs without turning the table into a battlefield. We’ll discuss why it’s okay for your child to skip a meal if they’re genuinely not hungry and how to encourage them to choose nutrient-dense foods rather than sugary or processed alternatives. Whether you’re a parent dealing with pickiness or simply an adult trying to honor your own body’s hunger signals, this episode offers a fresh perspective on mealtime “rules” and will help you and your family eat more intuitively.  Let’s foster an environment where our kids can discern their true hunger cues — and hopefully save you from some dinner table drama along the way.

In my widely-read article about how I cured my IBS symptoms, I recommended against eating eggs in the early stages of gut healing. And I got plenty of pushback for that recommendation. I understand why. Eggs are hailed as nature’s perfect superfood, have been a dietary staple for centuries, and their nutrient-packed yolks truly are nutritional powerhouses.  But not all parts of the egg are created equal, and the whites might be secretly sabotaging your digestion. In this episode, I break down the real differences between egg yolks and whites, explaining why those trendy egg-white omelets are basically plates full of nutritional trash. I also explain why some of the proteins in egg whites can trigger gut issues — especially if you’re prone to IBS or bloating — and share practical advice on choosing and preparing eggs to optimize digestion and nutrient absorption. Plus, I’ll give you the inside scoop from our own experience raising chickens on our homestead. You’ll learn why pasture-raised hens that are fed a true omnivore diet produce eggs with superior nutrient density, and how cooking your eggs the right way can make all the difference for your health. If you’ve ever struggled with digestive issues after enjoying eggs, this episode could crack open the solution you’ve been looking for.

Counting calories seems logical on the surface: just burn more calories than you eat and you'll lose weight, right? But what if this seemingly straightforward advice is deeply flawed, inaccurate, and a massive waste of your time? In this episode of the Primal Shift Podcast, I’m challenging one of the most entrenched myths in the health and fitness community: calorie counting. The truth is, your body isn’t a simple calculator — it’s a dynamic, complex system influenced by hormones, metabolism, and even the types of foods you choose. There's a huge gap between the calories you think you're burning and what your body is actually doing. Your smartwatch, fitness apps and even nutrition labels might lead you astray, with margin errors so big that your daily calculations become virtually meaningless. And that's before we even get into how different foods — protein versus carbs, for instance — are metabolized completely differently by the body. Instead of obsessing over calories, I suggest a radically simpler approach: prioritize protein, focus on satiety, and learn to tune into your metabolic signals. Because when your hormones (especially insulin) are balanced and your blood sugar stays stable, losing fat becomes infinitely easier. And if tracking helps you feel in control, forget calories and focus instead on how foods affect your body — perhaps through the use of a continuous glucose monitor. This episode isn’t just about debunking calorie myths. It’s about shifting your mindset to something more powerful: understanding your body’s true needs. Let’s stop counting imaginary numbers and start prioritizing real, nutrient-dense foods and listening to our own metabolic rhythms.

For decades, beef has been painted as the villain on our plates, blamed for heart disease, cancer, climate change, obesity, and even poor digestion. But have you ever stopped to question if these claims are backed by solid science, or are simply myths repeated often enough that they’ve become “common knowledge?” In this eye-opening episode of the Primal Shift Podcast, we’re cutting straight to the facts about beef, debunking one myth at a time. Is beef really clogging arteries, causing cancer, and leading to environmental ruin? Or is the true culprit hiding in plain sight: the processed carbs and ultra-processed foods often served alongside a juicy steak? We also dive into popular beliefs about vegetarian longevity, cholesterol fears, and even those trendy plant-based burgers that are being pushed everywhere you look. Spoiler alert: nature already perfected nutrient density, and it’s not found in highly-processed patties or lab-grown proteins. The truth is, beef can be one of your strongest nutritional allies, supporting metabolic health, lean muscle growth and overall vitality. And when cattle are raised properly, beef production doesn’t harm the environment — it actually helps restore ecosystems and sequester carbon, becoming part of the climate solution rather than the problem. So next time you’re told to swap your steak for quinoa or a lab-made burger, take a closer look at the facts and enjoy that ribeye without guilt. Join us as we dismantle decades of misinformation about beef, reclaiming our plates, our health, and even our planet. Stay primal, friends.

As a former pro triathlete, Brad Kearns used to push himself to the extremes of human endurance. He competed globally, chasing medals and personal records, only to eventually confront a humbling truth: his intense cardio regimen wasn’t building him up — it was slowly breaking his body down. Overtraining left him exhausted, inflamed, and far from the image of optimal health he once envisioned. Today, Kearns sees fitness differently. Rather than pushing endless mileage, he’s embraced shorter, more explosive movements like sprinting, jumping and lifting — movements that mimic our ancestral heritage, and that our bodies naturally crave.  In this episode of the Primal Shift podcast, we talk about why modern fitness culture has become hyper-focused on cardio, overlooking the fact that our bodies thrive when exposed to a balanced set of exercises. We also discuss the consequences of pushing too hard, too often, including skyrocketing cortisol, hampered metabolism and staggering injury rates. Kearns’ journey highlights the fact that optimal health is about nuance, not extremes. It’s about rediscovering a primal approach to movement that energizes rather than exhausts, and heals rather than harms. By shifting away from relentless endurance toward mindful, primal fitness, we reconnect with our evolutionary blueprint, supporting lifelong vitality rather than short-term achievements.

We like to think we can bend the rules when it comes to our sleep routine — for instance, by sleeping in after staying up late. And it’s true that sometimes that practice can leave us feeling just fine. But just because your body adapts to a late-night routine doesn’t mean it thrives on one. Sleep isn’t just about getting enough hours; it’s about getting them at the right time. And if you’re pushing your bedtime later and later, you could be sacrificing the most restorative phases of sleep without even realizing it.  Most of your deep sleep — the phase responsible for tissue repair, immune function, and growth hormone release — happens early in the night. This is when your body does its heavy lifting, repairing muscles, consolidating memories, and strengthening the immune system. Push your bedtime back and you’re cutting into the sleep that helps you recover and perform at your peak. And sleeping in the next morning won’t fully compensate for what you lost. So what about night owls? Some people swear they function better late at night. But is that biological, or just a habit? Evolutionary research suggests that in early human tribes, it made sense for some members to stay up later to keep watch while others slept. But just because a small percentage of the population may be wired to stay up later doesn’t mean modern habits like staring at screens late into the night, artificial lighting and erratic schedules aren’t making the problem worse. The truth is, your circadian rhythm is designed to sync with natural light. Morning sunlight tells your body it’s time to be awake and alert, while darkness in the evening signals the release of melatonin to prepare for sleep. When you ignore this cycle — whether by choice or necessity — you risk everything from poor recovery to hormone imbalances to sluggish metabolism and increased stress. So how do you reset your internal clock? Small, practical shifts make all the difference. Get outside first thing in the morning for at least 10 minutes of natural light. Cut back on screen exposure at night or wear blue light-blocking glasses if you must use devices. Instead of forcing yourself into an earlier bedtime all at once, shift it gradually — 15 minutes at a time — so your body can adjust naturally. These minor tweaks can lead to massive improvements in energy levels, mental clarity and metabolic health. If you’ve been struggling with grogginess, inconsistent sleep, or just want to optimize your recovery and performance, this episode will give you the tools to align your sleep with how your body was meant to function.  Learn more: Primal Shift Podcast #14: Do THIS for Better Sleep: https://www.youtube.com/watch?v=V72_fDrm_vI   Learn why you might have trouble falling asleep: https://michaelkummer.com/health/cant-fall-asleep/   Learn how to sleep better and fall asleep quicker: https://michaelkummer.com/health/sleep-guide/  Thank you to this episode’s sponsor, Peluva!

For Ciaran Flanagan, quitting alcohol wasn’t about having hit rock bottom — it was about realizing just how much better life could be without it. Like a lot of people growing up in Ireland, drinking was part of the culture he grew up in. He wasn’t an alcoholic, but he found himself caught in the same cycle so many people fall into: weekend drinking that derailed his focus, energy, and productivity for days. But after a month without alcohol, everything changed. His brain fog lifted, his sleep scores shot up, and he had more drive than ever before. And once he saw the difference, there was no going back. Flanagan is the founder of Inergize Health, a seven-figure wellness brand that’s redefining recovery with portable cold plunge therapy. In this episode, we talk about how dropping alcohol wasn’t just a health decision, but a complete shift in how he approached performance, recovery and resilience. That shift led him to cold plunging and breathwork, two powerful tools that helped him replace the false boost of alcohol with mental clarity, emotional stability, and sharper focus.  He shares why he prefers cold plunging after workouts and before bed, the science behind the dopamine and norepinephrine response, and how head-dunking triggers the mammalian dive reflex to boost cognitive function. We also dig into breathwork, including why it’s one of the simplest yet most overlooked tools for managing stress and sharpening focus. Like cold exposure, breathwork forces you into presence, training you to handle discomfort instead of running from it. And when you stack these practices, the results are undeniable. If you’ve ever wondered whether cutting out alcohol is worth it, or if you’re looking for practical ways to boost mental and physical resilience, this episode has something for you. Tune in to hear how Ciaran went from feeling “fine” to performing at a whole new level.

Testosterone is the engine of vitality and the foundation of muscle growth, energy, focus and resilience. Unfortunately, modern life can make it hard to maintain optimal levels, due to factors like poor diet, chronic stress and environmental toxins that can disrupt production at every step of the process. In this episode, we break down how testosterone is made, including why nutrient-dense foods (especially those rich in cholesterol, zinc, and Vitamin D) are critical, and how deficiencies in these key building blocks can tank your levels of this vital hormone. But diet isn’t the only factor. Poor sleep, excess body fat and exposure to synthetic estrogens from plastics and tap water all play a role in lowering T. We discuss how stress drives up cortisol, which directly suppresses testosterone production, and why lifestyle choices — like tight clothing and prolonged heat exposure — can further sabotage your hormones. More importantly, we cover practical, science-backed strategies to optimize testosterone naturally. That includes getting high-quality sleep, lifting heavy weights, spending time in the sun, and keeping your testes cool. We also dive into why pre-cooling before exercise can give your testosterone a major boost, and why avoiding plastics and chemical-laden personal care products matters more than you think. If you want to go even deeper, check out episodes 32 and 65, where we explore the downsides of testosterone replacement therapy and why T levels influence your ability to take on hard challenges. Testosterone production is complex, but small, consistent changes can make a massive impact. Tune in to learn how to take control of your hormones and build a lifestyle that supports optimal performance.

Sleep isn’t just about rest. It regulates everything from metabolism to cognitive function, and when it’s off, the entire body suffers. Yet for something so essential, many people struggle with it daily, caught in a cycle of stress, bad habits, and rigid expectations about what “good sleep” should look like. In this episode, sleep expert Nick Stewart shares a counterintuitive approach: instead of obsessing over perfect sleep, focus on flexibility. He explains why rigid sleep schedules often backfire, how worrying about lost sleep makes it even harder to fall asleep, and why humans are uniquely prone to sleep struggles compared to other animals. One of his most effective strategies? If you’re lying awake and feeling frustrated, get up. Move to a different room, create a calm environment, and only return to bed when you’re naturally drowsy. This simple shift has helped many people break free from years of insomnia. We also discuss how modern burnout is one of the biggest drivers of sleep issues, why the way you structure your day matters more than your bedtime routine, and how early morning sunlight exposure can dramatically improve sleep quality.  Stewart breaks down why most people overestimate their sleep needs, why education is the most powerful tool for improving sleep, and how small adjustments — like walking first thing in the morning or reframing sleep as a flexible process — can make a huge difference. If you’ve struggled with sleep, whether it’s falling asleep, staying asleep, or just waking up feeling rested, this conversation offers real, actionable strategies that go beyond the usual advice. Tune in to learn how to work with your body’s natural rhythms, reduce sleep anxiety, and create a routine that actually works.

We’re told that our healthcare system exists to keep us healthy, but what if it was never designed for that? In this episode, we trace the roots of modern medicine and nutrition to uncover how profit-driven interests shaped the way we approach health today — and why so many people are chronically sick despite significant medical advancements. It all started in the early 20th century, when John D. Rockefeller used his influence to centralize medical education, steering it away from nutrition and holistic care and toward a pharmaceutical-first approach. His reforms, built on the Flexner Report, ensured that doctors would be trained to treat symptoms with drugs rather than address root causes.  Later, Ancel Keys’ flawed research further distorted our understanding of health, vilifying saturated fats while paving the way for highly processed, industrial seed oils — ingredients that still dominate today’s ultra-processed food landscape. The food industry took this even further in the 1980s when major tobacco companies pivoted to food production, using their expertise in addiction to engineer products designed for overconsumption. The result? The population got hooked on cheap, nutrient-devoid foods while chronic disease skyrocketed.  Meanwhile, the medical system thrives on managing disease, not preventing it — because prevention doesn’t generate revenue. So where does that leave us? It means that reclaiming our health requires stepping outside the system. That starts with rejecting ultra-processed foods, prioritizing whole, nutrient-dense meals, and challenging the mainstream narratives about diet and disease. It also means seeking out medical professionals who focus on prevention and lifestyle interventions rather than prescriptions alone. The system isn’t going to change itself. But by making informed choices, we can take control of our own health.
