The Primal Shift

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 tha...

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 bemotrizi...

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, ...

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 si...

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...

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 bus...

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...

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 whi...

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 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 d...

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 a...

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 leucin...

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...

Most people think healthy food is expensive. But when you factor in healthcare costs, tax-funded subsidies, and environmental damage, you're actually paying three times what the price tag shows.

In this episode, I break down the hidden cost of processed food, how food subsidies and health outcomes are directly connected, and why the real food vs junk food cost comparison looks nothing like what you see at ...

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 kno...

Sun exposure isn't as simple as "eat clean and you're bulletproof." In this episode, I share how my sun exposure habits had to change after moving to a larger homestead — and why spending more time outdoors forced me to rethink everything I thought I knew. I break down why diet still matters for UV tolerance, what actually causes photo aging, how I structure my day to get sun safely, and why I rarely use sunscree...

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.
