In this episode of the Primal Shift podcast, I sit down with Dr. Rob Carter, an integrative physiologist who has spent 25 years studying what happens to human beings under pressure. His new book, The Convenience Trap, makes the case that modern life has quietly outsourced our navigation, memory, attention, and physical competence — leaving most adults measurably less capable than they were built to be. I like that argument, which is exactly why I pushed on it. "Modern life is making us weak" fee...

When news broke that the FDA finally approved bemotrizinol — the first new sunscreen ingredient cleared in the United States in over two decades — many people in the health community celebrated it as the ultimate breakthrough in sun protection. Since it’s been used safely across Europe for over 20 years and underwent extensive safety testing, the immediate assumption is that any bemotrizinol-based sunscreen hitting shelves is an automatic win for clean living. But that assumes the active i...

Carnivore was the eye-opener that showed me how to eliminate anything that could be bothering me, but five years later, animal-based is the framework that actually stuck. I've gone through paleo, keto, and carnivore, and none of them were failed attempts; each one raised the baseline and taught me something I still use today. In this episode, I break down the three things that actually changed (not my weight, not a number on a chart), why animal-based has outlasted every stricter diet I've trie...

Bryan Johnson was diagnosed with autoimmune gastritis in 2026, and within a day the internet had already decided it was his vegan diet — I don't think it's that simple. In this episode I break down what autoimmune gastritis actually is, why Bryan's own data (crashed ferritin, failed iron absorption, a second autoimmune condition since he was 21) points to something deeper than food alone, and why both sides of this argument — "it's the diet" and "diet has nothing to do with it" — are missing th...

My testosterone is 312 ng/dL. By most standards, that's low. But instead of panicking, I sat down and asked myself a simple question: is it actually a problem? In this episode, I walk through my own testosterone journey from TRT and hCG to where I've landed today, and why I'm not rushing to fix a number just because it's low. I look at the tradeoffs I've noticed between higher and lower T: appetite, libido, resting heart rate, HRV, even risk-taking. I also lay out the honest self-assessment I...

I'm 44, running multiple businesses, homeschooling my kids, and managing a 45-acre homestead. And I'm in better shape now than I was a decade ago. Not because I have more time. I don't. But because I stopped relying on motivation and built systems that work regardless of how I feel on any given day. In this episode, I walk you through the six pillars I use to stay in peak health during the busiest chapter of my life: nutrition anchored in animal protein, strength that comes from living and...

If you've spent any time in a gym, you've heard it: you need carbs to build muscle. It's gospel. Every bro coach and most personal trainers will tell you the same thing. The problem is it's not actually true. And my guest this week is living proof. Robert Sikes is a pro natural bodybuilder who has been ketogenic for 11 years, eating fewer than 20 grams of carbs a day the entire time. No rice, no grains, no oatmeal, none of the stuff bodybuilders are supposed to live on. And he competes and wi...

Most people treat sleep as a shopping problem — a new mattress, a supplement, a fancy tracker. But that's not what's broken. Your body is waiting for signals it evolved to read, and modern life stopped sending them. In this episode, I break down the three most common sleep problems — trouble falling asleep, staying asleep, and waking up exhausted — and walk you through how to identify which one you're actually dealing with. Then I give you a simple, free, week-by-week framework to start fixin...

There's a clip going around from a well-known homesteader implying that carrying heavy milk jugs is enough of a workout, and that you don't need to lift weights or do any structured training. I think that's worth pushing back on – not as body shaming or anything like that, but because the logic has a real flaw in it. There's an important distinction between maintaining your current level of fitness and actually improving it. If you're already in the shape you want to be in, manual labor can a...

Most of us eat by the clock, not by hunger. In this episode, I break down the difference between real physiological hunger and the cravings, habits, and schedules that drive most of our eating decisions — and why that distinction matters more than any diet. I share what happened when I skipped breakfast before a photo shoot in Miami, how ghrelin trains itself to your schedule, and why fasting for a day might be the simplest recalibration tool you're not using. If you can't skip a meal with...

Most people hear "buy the best meat you can afford" and immediately picture the $30 pasture-raised ribeye at Whole Foods — and then conclude that eating well is simply out of reach. But that's not a fair test of what quality meat actually costs. Ribeye is the most expensive cut at the highest tier, and comparing it to cheap conventional ground beef is like comparing a BMW to a used Corolla and deciding all cars are unaffordable. The more useful question is what "good enough" looks like across...

Most people treat the recommended daily protein intake as a target. It's not; it's the bare minimum to avoid getting sick, and I've been eating well above it for years without gaining fat or damaging my kidneys. In this episode, I break down how much protein you actually need per day, why protein timing for muscle matters less than how you dose it, and the one variable almost nobody talks about: the leucine threshold. Hit it per meal and you trigger muscle protein synthesis. Miss it and nothi...

Most of the mushroom supplements you'll find on Amazon are ground-up fruiting bodies or myceliated grain in a capsule. AHCC is something entirely different. It's a patented fermented extract from shiitake mycelia that has been used in over 1,000 cancer clinics worldwide, backed by more than 100 published studies, and studied specifically for its effects on natural killer cells, HPV clearance, autoimmune conditions, and liver disease. I'd never heard of it until Mimi Lindquist introduced me to it...

The other day my brother-in-law asked me a simple question: if you could go back to age 25 knowing what you know now, what would you do differently? The answer turned out to be anything but simple, because every change I'd make would unravel the chain of events that led me to where I am today. If I hadn't gotten into computers at 12, I probably wouldn't have gone into IT security. Without that career, I wouldn't have started my own company, moved to Switzerland, transferred to the US, met my ...

The main argument I hear when I encourage people to improve their diet is that healthy food is expensive. Compare the cost of a pound of grass-finished beef to fast food and the difference looks stark. But cheap food is the most expensive thing you'll ever buy. In the 1960s, the average American spent about 17% of their income on food. Today it's 10%, the lowest of any country on earth. Over roughly the same period, healthcare spending went from 9% of the economy to 18%. Food got cheaper and ...

Why bother with organ meat when you can just have a ribeye? After all, steak is already one of the most nutrient-dense foods on the planet. It's a fair question, and one I get all the time. The ancestral health world has generally answered it with "because our ancestors did" or "because predators eat the organs first," and while those things are true, they don't actually tell you what you need to know. The real question is how much more nutritious is an organ than a steak. Is it 10% more? ...

For years, I thought that if you eat right, ditch the seed oils and live a clean ancestral lifestyle, you become basically bulletproof in the sun. Just walk outside shirtless in July, no sunscreen, no problem. Your inner caveman will handle it. And to be clear, I still think diet matters enormously. But this spring I've been burned a few times, and it forced me to rethink my approach. What changed is that we moved to a larger property last fall and started homesteading at a completely differe...

I noticed something weird: body odor after drinking milk, but no digestive issues. That 48–72 hour delay told me lactose wasn't the culprit. In this episode, I explore why raw milk health benefits get oversimplified, and why the real differences matter: A2A2 milk vs A1 casein, how pasteurized milk inflammation compares to raw, and what my grass fed dairy microbiome response actually means. I break down: Why raw milk body odor happens (and what the timing reveals) Milk digestion ...

If you've been following me for any amount of time, you know I've had strong opinions on diet, training, and what belongs on your plate. Some of those opinions I've walked back. Not because I was wrong about everything, but because I've learned more, lived more, and stopped clinging to ideas just because they were mine. How you handle being wrong says a lot more about you than how confident you were when you thought you were right. And when you build an audience or even just a social circle a...

Your food can only be as nutrient dense as the soil it was grown in. That's the realization I had after testing the soil across our new property and discovering that despite being relatively fertile and rich in magnesium, it was far too acidic for plants to absorb those minerals properly. Soil pH is a gatekeeper: if it's off, the nutrients stay locked in the ground even when they're technically present. That sent me down a rabbit hole of soil depletion and food nutrient density, and the da...

Your body already knows how to live to 120 in perfect health. It's just not doing it. That realization is what sent Dr. Chris Rhodes down the fasting research path during his PhD in nutritional biochemistry at UC Davis. His argument? Most people doing 16:8 intermittent fasting aren't getting nearly the benefits they think they are. The body doesn't flip into fasting mode until glycogen stores are depleted, which typically takes 20 to 24 hours. Autophagy, stem cell regeneration, and the real a...

Most people who start an animal-based diet assume the goal is to eliminate every plant from the plate. I get it: when you've spent years being told kale is a superfood and you finally learn it's loaded with oxalates and goitrogens, the pendulum swings hard. It did for me. But the blanket "plants are bad" framing leaves a lot on the table. Plants aren't health foods. They don't want to be eaten, and they evolved with chemical defenses to discourage exactly that. Our dietary foundation at the K...

All plants are toxic to varying degrees. I haven't changed my mind on that. But recently our oldest daughter came up with a business idea: – making salves from plantain leaves infused in beeswax and olive oil for their antibacterial properties — and it got me thinking about the role plants actually play in our household despite the fact that we're very much an animal-based, meat-centric family. The truth is, we do eat plants. We always have. The foundation hasn't changed — meat, organs, eggs,...

Most people assume eight hours of uninterrupted sleep is the biological default. It isn't. For the vast majority of human history, people slept in two distinct phases — waking naturally in the middle of the night for prayer, reflection, and quiet work before returning to sleep until dawn. In this episode, we explore what ancestral sleep patterns actually looked like, what the science says about biphasic and split sleep, and why your 3 AM wake-up might not be insomnia. We also break down ultra...
