In this episode, I explore whether following an ancestral diet and traditional eating habits is enough to keep us healthy today. While our grandparents thrived on simple meals, the reality of modern food quality, hidden environmental toxins, and processed foods inflammation paint a different picture. I share how chronic stress and health challenges, along with changes like A1 vs A2 milk casein, affect our bodies in ways past generations didn’t face. We’ll look at why homesteading health problems persist despite “clean eating,” and how a slow living lifestyle can help bridge the genetic mismatch modern diet creates. Tune in to uncover the real reasons why eating like your grandparents won’t save you.

#Diet #Nutrition

In this episode, I share a fascinating 1950s endurance experiment with rats that uncovered what researchers called an “anti-fatigue factor” in beef liver. The results highlight why organ meats like liver are nature’s ultimate multivitamin and how even small micronutrient deficiencies can wreck ATP energy production, mitochondrial health, and overall performance. I’ll walk you through what the study revealed, how it ties into modern fatigue and performance issues, and why I believe high-quality liver supplements are one of the simplest ways to cover nutritional gaps. If you’ve ever wondered about beef liver benefits or why organ meats nutrition matters, this story will change how you think about natural energy.

#BeefLiver #EnergyLevels   

For years I thrived on two large meals a day – a late-morning breakfast after training and an early dinner. And the results spoke for themselves: stable blood sugar, excellent insulin sensitivity, low body fat, and plenty of energy. 

But I began noticing a drawback. Those evening meals, heavy in protein and fat, kept my digestive system working for hours after I went to bed, raising my heart rate, lowering my HRV, and occasionally causing acid reflux. Shifting dinner earlier didn’t help much, and I wasn’t hungry first thing in the morning, so forcing an earlier breakfast felt just as unnatural.

In this episode, I break down why I’ve shifted from two meals to three, and what that change has done for my energy, recovery, and sleep quality. I walk through the benefits I saw from a two-meal pattern, the specific problems that crept in over time, and how spreading my daily protein and calorie intake across breakfast, lunch, and dinner has improved digestion, lowered nighttime stress on my body, and left me waking up more refreshed.

The takeaway isn’t that everyone should eat three times a day – or twice, or just once. It’s that meal timing and frequency should fit your body’s needs, your goals, and your lifestyle. The right pattern for you is the one that leaves you feeling and performing your best. For me right now, that means three balanced meals, each big enough to satisfy without overloading my digestion before sleep.

Too much estrogen — even the fake kind — is wrecking our health. In this episode, Kathy and I break down the hidden endocrine disruptors lurking in your bathroom: shampoos, lotions, deodorants, candles, and even “natural” products that aren’t so natural.

We share the exact non-toxic swaps we’ve made over the years (without breaking the bank), and why some “clean” labels still aren’t enough. We also dive into feminine health, EMF mitigation, and the real reason birth control might be one of the most damaging drugs women are prescribed — and what to do instead.

This is Part 2 of our series on everyday toxins and how to avoid them — simple shifts that protect your hormones, fertility, skin, and long-term health.

#NonToxicProducts #WellnessOptimization   

When most people think about saving the planet, they picture cutting back on meat and eating more plants. But what if the story we’ve been told about how plant-based diets equate to sustainability is missing half the truth (and hiding a massive environmental cost)?

In this episode of the Primal Shift Podcast, I pull back the curtain on the industrial food system most people never see. 

From the 90 billion honeybees trucked across the country each spring to pollinate almond trees to the 7.3 billion wild animals killed each year by harvest machinery, the data tells a very different story than the slogans.

This isn’t about pitting vegans against meat-eaters. It’s about showing how industrial monoculture destroys soil, collapses insect populations, drains water tables, and kills countless small mammals and pollinators in the name of “clean” eating. 

If you’re ready to rethink food systems from the soil up, this episode is for you. 🎉 Special Announcement: Ep. 100 GIVEAWAY! 🎉

#Vegan #Plants #Animals #Diet 

For most of human history, survival depended on eating the foods that gave us the most nutrients with the least effort. That usually meant animals, which are dense in protein, fat, and bioavailable vitamins and minerals. But in recent years, we’ve been told that plants are the true superfoods. 

Raw kale in your smoothie? Spinach salads every day? The darker and leafier, the better, right? Not quite.

In this episode, I dive into the real story behind plant-based foods and the antinutrients they contain, as well as how they compare to animal-based sources of nutrition. 

We’ll talk about why humans evolved to thrive on meat, how plants defend themselves with chemical compounds like oxalates, lectins and goitrogens, and what all that means for your health. And I’ll share practical tips for how to prepare the least toxic plants safely — when and if you choose to include them in your diet.

After struggling with IBS for over 30 years, I fixed my gut issues through a radical shift in how I approached food. It wasn’t about chasing superfoods or stacking more supplements. It was about eliminating the things that were holding me back, and embracing the nutrient-dense, low-toxin foods that our ancestors relied on for thousands of years.

If you’re eating spinach every day or downing kale smoothies because they’re “healthy,” you might want to take a closer look at what those foods are actually doing to your body. And if you’ve avoided organ meats because of the taste, I’ll share a simple way to get their benefits without having to touch a skillet.

This episode isn’t about fearmongering or food dogma. It’s about reclaiming clarity, understanding what’s actually nourishing, what’s neutral, and what might be slowly working against you.

#Carnivore #Vegan #Plants #Animals 

It’s easy to assume that food affects everyone the same way. But when my wife Kathy and I wore continuous glucose monitors for two weeks, we learned just how different our responses actually are. 

For example, a bowl of curry or a few slices of sourdough bread would send her blood sugar soaring while barely impacting mine, and vice versa. 

We weren’t just tracking data: we were uncovering real-time insight into how our individual metabolisms, hormones, stress, and even muscle mass shape our daily health outcomes.

The experiment revealed a few surprising truths. For Kathy, sourdough and rice were consistent triggers, even when paired with protein and fat. Her blood sugar spiked above 200 mg/dL and stayed elevated for hours — a clear sign that not all “healthy carbs” are created equal. 

For me, the biggest spike didn’t come from food at all. It came from intense physical activity — proof that exercise-induced glucose changes are an entirely different metabolic story than post-meal crashes.

The differences went deeper than food. Kathy’s menstrual cycle impacted her insulin sensitivity, and my lean muscle mass gave me an edge when it came to buffering glucose. We also saw how stress, sleep and cold plunging could subtly (and sometimes dramatically) influence blood sugar trends, even in the absence of a single bite of food.

None of this was about fearmongering over carbs or obsessing over numbers. Wearing a CGM isn’t a lifestyle; it’s a short-term lens into how your body actually works. And once you connect the data to how you feel — sluggish after rice, energized after steak, restless after a late-night spike — that’s when you unlock real change.

If you’re serious about optimizing your health, I highly recommend trying a CGM for just a few weeks. Learn what your body thrives on. Understand what derails you. And then build your habits accordingly. Because personalized data beats generic diet advice every time.

#LevelsHealth #CGM 

Biohacking wasn’t always about gadgets. It used to be about building a better lifestyle by fixing root causes with movement, light, food and sleep. But somewhere along the way, optimization gave way to outsourcing. Today, it’s easy to mistake a tech solution for progress when it’s really just a more expensive version of the same mistake: treating symptoms instead of addressing causes.

That shift was on full display at a recent biohacking conference I attended, where nearly every product promised better sleep, more energy or deeper calm — without requiring any meaningful change. The sales pitch has become eerily similar to Big Pharma: just take this “drug” and feel better… no behavior change required.

But health doesn’t work like that. Wearing blue light blocking glasses while scrolling TikTok in bed misses the point. Slapping a mood gadget around your neck doesn’t solve emotional imbalance. And leaning on sleep tech while ignoring your circadian rhythm or pounding caffeine at 4 p.m. won’t fix recovery. Tools can support change, but too often, they delay it.

I use plenty of tech myself: cold plunges, saunas and wearables to name a few. But I use them with intention. If I lived near a freezing lake, I’d ditch the plunge. If tracking sleep started creating stress, I’d take the ring off. Tools are valuable only when they move us toward better habits — not when they distract us from them.

Ask yourself: is this device helping you build something real, or is it letting you avoid what needs to change? That’s the litmus test. If you’re micromanaging every glucose spike or feeling anxious about your recovery score, it might be time to simplify. You can’t outsource health. You can only build it, one habit at a time.

Thank you to this episode’s sponsor, Peluva!

Peluva makes minimalist shoes to support optimal foot, back and joint health. I started wearing Peluvas several months ago, and I haven’t worn regular shoes since. I encourage you to consider trading your sneakers or training shoes for a pair of Peluvas, and then watch the health of your feet and lower back improve while reducing your risk of injury.
