That's So Primal

Animal-Based Nutrition Basics

If you have been wondering what the primal diet actually is, here is the whole thing in one sentence: eat the way humans ate before factories started making our food.

That is it. That is the diet.

These days people call it animal-based. You build your meals around animal foods (meat, eggs, dairy if you tolerate it) and round them out with the plant foods humans have always eaten (fruit, vegetables, honey). What is new is not the food. What is new is that we spent fifty years being told to fear it.

The short version: eat this, skip that

Let us keep this stupid simple.

Eat: beef, lamb, pork, chicken, fish, eggs. Organs if you are feeling brave (start with liver mixed into ground beef, you will not taste it). Butter, tallow, lard. Raw cheese and heavy cream if dairy agrees with you. Fruit. Vegetables. White rice and potatoes if you are active. Honey. Salt. Lots of salt.

Skip: seed oils (canola, soybean, corn, and their sneaky cousins). Ultra-processed anything. Sugary drinks. The snack aisle, blah blah, you know the stuff. Cannot pronounce it? That is your answer.

Why meat sits at the center

Here is the part the headlines skip: meat is the most nutrient-dense food you can put on a plate. A ribeye hands you complete protein, B12, zinc, and heme iron in the form your body actually absorbs. Good luck getting that from a fortified cereal.

Protein also keeps you full in a way carbs do not. Researchers reviewing the evidence found that protein increases satiety more than carbohydrate or fat, bumps up thermogenesis, and helps you hold onto muscle while you lean out (Paddon-Jones et al., 2008).

And about the red meat scaremongering: when an international panel graded the actual evidence behind the eat-less-red-meat guidelines, they called it low-certainty evidence and issued a weak recommendation (Johnston et al., 2019). Translation: the science is a lot less settled than the headlines pretend.

Fat is fuel, not the enemy

Somewhere along the way, fat became the villain. The problem was never fat. The problem was which fats.

A meta-analysis of 21 studies following nearly 350,000 people found no significant link between saturated fat intake and heart disease or stroke (Siri-Tarino et al., 2010). Read that again. The thing we have been told to fear for decades did not hold up.

What does cause problems is the other stuff: industrial seed oils that oxidize inside you and drive inflammation. So we cook with the fats humans have always cooked with. Tallow for searing, butter for everything else. If you want to try it, this is the grass-fed tallow I keep next to the stove.

What about cholesterol?

Straight answer: the cholesterol story is messier than either side admits. One big 2019 analysis did link higher dietary cholesterol and egg intake to more heart events (Zhong et al., 2019). It is observational, not a lab experiment, but I am not pretending it does not exist.

I eat eggs most days (my cast iron steak and eggs is basically a food group at this point) and I am not losing sleep over it. Food first, fear never.

Carbs: earn them

I am not anti-carb. I am anti-mindless-carb.

A good baseline is staying under about 150 grams a day, which is easy when your meals are meat, veggies, and fruit. The standard American diet blows past 300 without trying (cereal, sandwich, pasta, repeat), and all that extra energy has one place to go: storage.

But if you are training, lifting, or sprinting? You earn your carbs. White rice, potatoes, fruit, honey. Clean sources, eaten on purpose, not inhaled from a bag.

The real enemy is ultra-processed food

If you only change one thing, make it this: quit ultra-processed food.

In a tightly controlled NIH trial, people in a metabolic ward ate about 500 extra calories a day on ultra-processed meals versus unprocessed ones, even with macros, sugar, sodium, and fiber matched. They gained on the junk and lost on the real food (Hall et al., 2019).

Same calories on paper. Completely different result in the body. That is the whole game.

How to start this week

Three steps. That is all.

1. Build every meal around a protein. Meat, eggs, fish. Eat plenty, especially if you are training.

2. Swap your cooking fat. Out: the plastic bottle of canola. In: tallow, butter, or lard. A 12-inch cast iron skillet (this is the one I use) plus hot tallow will handle 90 percent of your cooking.

3. Salt your food like you mean it. Real salt, not the blue canister dust. When you drop processed food, your sodium drops with it, and you will feel it. This is the salt in our kitchen.

Do that for two weeks and pay attention. Most people notice the afternoon crash disappears first.

That is the basics. No dogma, no 47 rules. Eat animals, eat plants, skip the factory stuff.

Why You’re Still Tired After 8 Hours of Sleep

You got your eight hours. You went to bed at a reasonable time, you woke up when the alarm went off, and you still feel like you got hit by a truck. If that sounds familiar, the problem is not how long you slept. It is your sleep quality, and there is a big difference between the two. Hours in bed mean nothing if your body never got the signal that it was actually nighttime.

Think of it like food. You can eat 3,000 calories of gas station snacks and still be malnourished. Eight hours of shallow, light-polluted sleep will not do what six hours of deep, dark sleep can do. The fix does not require a new mattress. It requires getting your light right, because light is the main signal your body uses to run the whole operation.

Your Body Runs on Light Signals

Deep in your brain a master clock runs your sleep and wake cycles. It does not check your phone. It reads light: bright mornings start the day, darkness triggers melatonin.

University of Colorado researchers took people camping for one weekend. No flashlights, no phones, just sun by day and firelight after dark. Their clocks synced with the solar day within days. You can read the full camping study here. Your body still knows how to do this. It is just confused by your living room.

Step one is free. Get outside in the morning, no sunglasses, ten or fifteen minutes. Walk the dog, coffee on the porch, whatever. That light anchors your clock so melatonin shows up on time that night.

The Evening Light Problem

Your ancestors got darkness after sunset. You get overhead LEDs, a glowing TV, and a phone six inches from your face until midnight. Your brain reads all of that as daytime.

Harvard researchers found ordinary room light before bed suppresses melatonin. Not stadium lighting, just normal lamps. Screens are worse. In a study comparing iPad reading to paper books, the screen readers took longer to fall asleep, got less REM sleep, and felt groggier the next morning.

This is why “but I was in bed for eight hours” misses the point. If your melatonin showed up two hours late because of light, your eight hours were really six hours of real sleep wearing an eight-hour costume.

The fix is simple. Dim the house after dinner and use lamps instead of overheads. If screens are unavoidable at night, a pair of amber blue-light blocking glasses like these is a reasonable bet. A 2025 meta-analysis of randomized trials found only small, non-significant improvements, so call the evidence mixed rather than settled. Put them on an hour or two before bed. You will look ridiculous and sleep great.

Make Your Bedroom a Cave

Now handle the light during bed. Your eyelids are not blackout curtains. Streetlights, hallway LEDs, and that one blinking router all chip away at your deep sleep. Your room should be so dark you cannot see your hand in front of your face.

If streetlights or early sunrises are fighting you, a set of real blackout curtains is one of the highest-value purchases in this whole lifestyle. Keep the room cool too, somewhere in the mid-60s, since your core temp has to drop to fall asleep. Crack a window or run a fan.

For light you cannot control, like hotel rooms or a partner who reads in bed, a proper sleep mask like the Manta is worth every penny. The cheap flat ones press on your eyes and slide off. A contoured one blocks everything and you forget it is there.

Small Changes That Actually Improve Sleep Quality

Light is the biggest lever for sleep quality, but a few smaller habits stack up fast. First, stop eating big meals right before bed. A huge late dinner keeps your body digesting when it should be repairing. Give yourself two to three hours between your last meal and lights out. A solid protein-forward dinner earlier in the evening beats a midnight snack every time.

Second, watch the caffeine clock. Its half-life is five to six hours, so your 3 PM coffee is still in your system at 10 PM. Set a hard cutoff at noon and see what happens.

Third, keep a consistent wake time, even on weekends. Sleeping in shoves your clock later and makes Monday miserable. That weekend shift has a name, social jet lag, and large reviews tie short and mistimed sleep to higher risk of blood sugar problems. A steady wake time is free and it works.

None of this is exotic. Morning light, dim evenings, a dark cool room, no late feasts, a caffeine curfew, and a steady wake time. Boring, cheap, and better for your sleep quality than eight hours of junk sleep.

Primal Takeaway

Your body already knows how to sleep. It just needs the right signals: bright days, dark nights, and a cool cave to do it in. Fix your light and the sleep fixes itself.

Are Dates Healthy? Science Says Yes (Here’s Why)

A few days ago I posted a reel that said “sugar is healthy” and the comments did exactly what I wanted them to do. So let’s settle it properly: are dates healthy, or am I just rationalizing my sweet tooth? Short answer: dates are one of the best sweet things you can eat. Here is the long answer.

A Medjool date is roughly 80 percent sugar by weight. That sounds disqualifying until you look at what the sugar comes wrapped in: fiber, potassium, magnesium, and a pile of polyphenols. The packaging is the whole point. Strip all of that away and you get white sugar. Keep it, and you get a fruit that behaves nothing like candy in your body.

Are Dates Healthy? What the Research Says

The first thing people worry about is blood sugar, which is fair. But researchers who measured the glycemic index of five date varieties found low to medium GI values in both healthy people and people with type 2 diabetes, with no dramatic post-meal glucose spikes. The fiber and the whole fruit matrix slow everything down. Sugar in a date does not behave like sugar in a soda.

It gets better. A randomized trial had adults with pre-diabetes and type 2 diabetes eat a small daily dose of dates while researchers tracked glycemic control, lipids, and quality of life. The results were reassuring, not alarming. Dates fit into the picture without wrecking it. If you are rebuilding your relationship with fruit, this is a good sign.

There Is More in There Than Sugar

Then there is everything else in the fruit. A systematic review of the phenolic content in ripe dates found a potent load of antioxidant compounds, which is a big part of why dates punch above their weight nutritionally. Another study profiling dates as a functional food highlighted their fiber and oligosaccharides, the exact stuff your gut bacteria thrive on.

My favorite date study has nothing to do with any of that. Researchers had pregnant women eat six dates a day for the last four weeks before delivery, and the date group had shorter labors and needed less induction and augmentation. I will never be pregnant, but I respect a fruit with that kind of resume.

Dates vs. Other Sweeteners

Honey and maple syrup get a lot of love in the natural food world, and they are both fine. But neither one brings fiber to the party, because the fiber got left behind in processing. A date is the whole food. That is the entire difference, and it is a big one. Agave is the worst of the bunch: mostly fructose, minimal nutrients, great marketing. If your sweet tooth needs feeding, the hierarchy is simple. Whole dates first, date syrup second, honey or maple when a recipe calls for them, and agave never.

How I Eat Them

Three dates a day. That is my number. I eat them whole, not as juice and not blended into some “healthy” dessert that has fourteen other ingredients. Whole fruit means the fiber is actually doing its job. Sometimes it is after lunch, sometimes it is the thing standing between me and the pantry at 3 PM.

That is why, when people ask me are dates healthy, I just point at the fruit bowl. Nothing about a date was invented in a lab. No proprietary blend, no “natural flavors,” no ingredient list you need a chemistry degree to read.

If you want a sweetener for coffee or baking, date syrup like this one is literally just dates and nothing else. Compare that ingredient list to whatever is in the sweetener aisle and tell me which one your grandmother would recognize.

One more thing worth knowing: dates make a great pre-workout. Fast carbs, potassium, magnesium, and easy on the stomach. Two or three dates about half an hour before you train beats any neon-colored powder I have ever tried.

What to Buy

Not all dates are equal. You want soft, fresh Medjools, not the dried-out bricks fossilizing at the bottom of the bulk bin. These Joolies organic Medjools are grown in California and taste like caramel. Store them in airtight glass jars like these and they will stay soft for weeks. Buy in bulk and keep them in the fridge, and they last even longer.

Primal Takeaway

Sugar is not the enemy. Naked, refined, stripped-of-everything sugar is. So are dates healthy? By every measure that matters, yes. Dates are proof that sweetness and nutrition can live in the same food. Eat the fruit.

How to Fix Your Evening Circadian Rhythm for Deep Sleep

Modern environments are designed to disrupt your biology. We sit under high-intensity fluorescent lights all day, stare at glowing screens past midnight, and then wonder why we wake up feeling exhausted. In fact, extensive research on modern light exposure shows how chronic artificial lighting drastically impairs both sleep quality and metabolic health. Restoring a healthy evening circadian rhythm isn’t about buying expensive sleep trackers or taking handfuls of supplements. It’s about changing the environmental signals you send your brain after the sun goes down.

The Problem with Modern Nighttime Lighting

Your brain uses light cues to regulate hormone production. For thousands of generations, sunset was the ultimate signal that the day was over. A landmark study on evening light exposure demonstrates that typical room lighting alone can profoundly suppress your body’s natural melatonin onset, delaying deep recovery. Today, artificial blue light from phones, televisions, and overhead LED bulbs tricks your central clock into thinking it’s still noon.

When you fix your evening circadian rhythm, you stop fighting your biology. Lowering your light exposure after dark allows your nervous system to down-shift naturally from high-stress alertness into rest-and-digest mode. If you want to optimize the rest of your daily habits, check out our thoughts on primal lifestyle staples for simple ways to build better routines.

Three Simple Shifts for Better Sleep

You don’t need to live in absolute darkness, but you do need to be intentional about your home’s lighting environment once the sun sets.

Kill Overhead Lighting: Turn off high ceiling lights after dinner. Use low-placed floor lamps with warm, dim bulbs instead, like Hooga Amber Sleep Bulbs, which emit zero blue light.
Set a Screen Curfew: Put electronic devices away at least one hour before bed. Instead of using your phone to wake up (which tempts you to scroll), rely on a simple wooden digital alarm clock with a dimmable display.
Black Out the Bedroom: Block all exterior streetlights with heavy-duty blackout curtains and cover annoying LED indicator lights on electronics inside your room using LightDims blocking stickers.

Scientific literature on human sleep physiology shows that light exposure late in the evening directly suppresses nocturnal melatonin secretion, impairing sleep quality (eReader melatonin suppression research). Furthermore, research reveals that even outdoor artificial light creeping through your windows significantly reduces sleep efficiency (outdoor light at night study). Conversely, clinical trials demonstrate that aligning your light exposure patterns with natural daylight cycles significantly improves daytime energy and nighttime rest (daylight circadian alignment study).

Simple Tools for Environment Control

Controlling your lighting environment can be tough if you live in a bright city or travel frequently. A quick fix is using a solid pair of Uvex Skyper Blue Light Blocking Glasses in the evening to filter out harsh wavelengths while you wind down.

Primal Takeaway

Respect the sunset. Rebuilding a natural evening circadian rhythm comes down to dimming artificial lights, shutting down screens, and creating a dark cave for deep recovery.

Cast Iron Skillet Steak and Eggs: The Simple Ancestral Breakfast

If you’re still starting your morning with a bowl of processed cereal or a dry piece of toast, you’re setting yourself up for an inevitable energy crash before 10 AM. Modern morning routines have us hooked on quick sugar, but your biology thrives on dense protein and healthy fats. Searing a proper skillet steak and eggs in real grass-fed butter isn’t fancy, but it’s the absolute cleanest way to fuel your engine for the day ahead.

Why You Need a Cast Iron Skillet Steak and Eggs Strategy

Most people skip cooked breakfasts because they think it takes too long. In reality, whipping up a cast iron skillet steak and eggs takes under ten minutes if you use thin-sliced cuts like ribeye or flank steak. When you heat up a solid cast iron pan, you get an incredible sear without touching toxic non-stick coatings. Plus, cooking with real animal fats like butter or a high-quality grass-fed beef tallow ensures you aren’t consuming oxidized seed oils first thing in the morning—a practice strongly linked to harmful lipid oxidation and inflammation.

When you start your day with heavy protein, your body releases satiety hormones that keep your blood sugar steady. If you want to dive deeper into why trading grains for animal proteins changes your metabolic health, check out our guide on animal based nutrition basics to see the full framework.

Ingredients for the Ultimate Morning Skillet

You don’t need a long list of groceries for this. Simple, high-quality ingredients are always better than complicated sauces loaded with preservatives.

Cast Iron Skillet Steak and Eggs

Print Recipe Pin Recipe

Prep Time 5

Cook Time 10

Servings: 1

Course: Breakfast

Ingredients Method

Ingredients

8-10 oz Thin-sliced ribeye
3 Pasture-raised eggs
2 tbsp Grass-fed butter
Coarse sea salt & black pepper to taste; unrefined mineral salt recommended

Method

Place a cast iron skillet over medium-high heat for about 3 minutes until piping hot.
Season both sides of the ribeye liberally with coarse sea salt.
Add 1 tbsp butter; when foaming, sear the steak 90 seconds untouched, flip, sear 1 more minute, then transfer to a plate to rest.
Reduce heat to medium-low and add the remaining 1 tbsp butter to the pan drippings.
Crack the eggs into the butter and cook slowly until the whites are set but the yolks stay runny.
Slide the eggs next to the steak and spoon the extra butter drippings over the top.

Step-by-Step Cooking Instructions

Get your pan piping hot before anything hits the surface. A cold pan leads to gray, boiled meat instead of a deep, caramelized crust.

First, place your cast iron pan over medium-high heat for about three minutes. Season both sides of your thin ribeye liberally with coarse sea salt. Drop one tablespoon of butter into the hot pan, letting it foam up without burning. Place the steak into the skillet and let it sear untouched for 90 seconds. If you want to be absolutely precise with your doneness, tap it with a reliable digital meat thermometer. Flip it using a sturdy metal spatula, sear for another minute, and transfer it to a plate to rest.

Turn the burner down to medium-low. Add your second tablespoon of butter to the remaining pan drippings. Crack your eggs directly into the butter. Cook them slowly until the whites are set but the yolks remain runny. Slide the eggs right next to your resting steak, spooning any extra butter drippings directly over the top.

Medical research on nutrient density highlights how whole food protein sources support muscle synthesis and sustained satiety throughout the morning (dietary protein and satiety study). Furthermore, clinical data on lipid consumption demonstrates that stable animal fats do not drive health issues like we were once told—in fact, a major meta-analysis on saturated fat found no significant evidence linking dietary saturated fat to an increased risk of cardiovascular disease.

Gear Up Your Kitchen

If you’re still using lightweight aluminum pans, it’s time to upgrade your tools. Cooking real food requires heavy gear that holds heat evenly, lasts a lifetime, and can even naturally boost your dietary iron intake. I recommend grabbing a solid Lodge Cast Iron Skillet so you can execute high-heat sears without worrying about synthetic chemical flaking.

Primal Takeaway

Ditch the boxed breakfast products and return to the basics. Searing a quick skillet steak and eggs gives your body stable energy, zero sugar crashes, and the raw building blocks it needs to thrive all day.
