I use the most natural shampoos I have access to, a natural conditioner once a week, and I trim my hair two or three times a year. I never comb my hair — I use my fingers under the shower. I massage my scalp with my hands almost daily.

I am 44, I have no gray hair and I do not think that is a coincidence.

That is the entirety of my hair care routine.

But it was not always this simple.

Before I started the Paleolithic Ketogenic Diet, my hair was thinning, I had scalp eczema, and it was falling more than it should. It looked dry, sparse, and dull in a way that no product could fix. I tried different things but nothing made a lasting difference. At that point of my life I still believed the solution was to be found in an external product.

Photo: me as a vegan before starting my carnivore journey

I know how you feel, I went through it all!

Around six months after starting PKD — eating fatty cuts of ruminant meat, organs, bone marrow, tallow, suet — something shifted.

My hair stopped falling the way it had been, the texture changed, it became stronger and brighter, no more dullness.

I did not add a product or a supplement. On the contrary — I stopped all of that and let go of the belief that the answer was somewhere in a bottle.

What changed was what I was feeding my body, and the body, given the right building blocks, did what it is designed to do.

Most conversations about hair health happen from the outside in.

Which shampoo, which treatment, which mask, which oil…

But hair is built from the inside.

Every strand begins in a follicle that depends on a constant supply of specific nutrients — amino acids, fatty acids, vitamins, and minerals — to grow, maintain its structure, and hold its color and texture over time.

When those nutrients are missing or insufficient, the follicle cannot do its job properly and the result is hair that thins, breaks, falls, or simply stops growing the way it should.

No external product changes that, the raw materials have to come from food.

This is where nose-to-tail eating becomes relevant.

The modern diet — even a relatively healthy one — is often missing some of the most important nutrients for hair health. The parts of the animal that contain the highest concentrations of those nutrients are the parts most people no longer eat.

Here is what changes when you start eating the whole animal.

Protein and amino acids

Hair is made almost entirely of keratin, a structural protein. Building keratin requires a consistent supply of amino acids — particularly glycine, proline, and cysteine.

Muscle meat provides protein, but it is relatively low in glycine and proline. Those amino acids are found in abundance in connective tissue, skin, bone broth, and collagen-rich cuts — the parts of the animal that have been largely removed from the modern diet.

When the diet includes the whole animal, the amino acid profile becomes significantly more complete.

Collagen and connective tissue

Collagen supports the structure of hair follicles, the integrity of the scalp, and the health of the skin surrounding each follicle. Collagen production requires glycine and proline — found in the parts of the animal most people discard.

Bone marrow, oxtail and slow-cooked cuts are among the richest sources of the compounds that support collagen synthesis.

Fat-soluble vitamins

Vitamins A, D, E, and K are essential for cellular health, hormone regulation, and tissue repair, all of which directly affect the health of hair follicles.

The most bioavailable forms of these vitamins are found in animal fats and organ meats. Liver is one of the most concentrated sources of vitamin A in the human diet. Suet, lard, and marrow provide fat-soluble vitamins in a form the body can use directly, without conversion.

A diet that avoids animal fat is often low in these nutrients — and the hair follicle is one of the first places that deficiency becomes visible.

Zinc and iron

Both are critical for hair growth and follicle function. Both are found in significantly higher concentrations in animal foods than in plant sources, and in a more bioavailable form.

Red meat, particularly fatty ruminant meat, is one of the most reliable dietary sources of both.

Biotin and B vitamins

Liver is one of the richest sources of biotin and B12 in the human diet.

B vitamins play a central role in cellular energy production, which means follicle cells — among the most rapidly dividing cells in the body — depend on them constantly.

Most people look for biotin in supplements without knowing that in a nose-to-tail approach, it comes from food.

What strikes me most, looking back, is how simple the shift was.

I did not start a new supplement or hair product. I simply started eating the parts of the animal that humans have always eaten — the organs, the fat, the marrow, the cuts that took time to prepare — and the body responded.

It took around six months of consistency before I noticed the change. I honestly did not care much about my hair at the time — I had other conditions that were more important to me to address. But the change arrived, it was real and it has stayed.

Hair is often treated as a cosmetic concern, but the body does not see it that way.

Hair follicles are metabolically active, they require a steady supply of nutrients to function and when that supply is adequate, follicles do what they are designed to do.

When it is not, the body makes a decision: it redirects resources away from hair — which is not essential for survival — and toward the systems that are. This is not a malfunction, it is the body responding intelligently to what it has available.

When the body has what it needs, it can afford to invest in hair again and this is what nose-to-tail eating does.

From the outside, she looked disciplined.

But her body was not responding the way she expected.

She came to me in her early forties.

Frustrated. Tired. Doing a lot and feeling like the effort was not translating into results.

Her nutrition looked solid.

That was not the first place I wanted to look.

What caught my attention was the rest of her week.

She was going to bed somewhere between midnight and 2 a.m. and waking up around 6 a.m. to train.

Five hours of sleep on a good night.

The first thing she looked at every morning was a screen.

The last thing she looked at every night was a screen.

She trained twice a day: cardio before work, strength training in the evening.

She worked in an office all day, away from natural light.

She rarely saw friends. There was very little time left. Training, working full time, tracking, preparing, keeping up — it had taken over.

And when she rested, she felt guilty. Rest felt like something she had to earn.

So she kept going.

One thing she could not understand was her body composition.

She was training to build muscle, she was eating for performance, but the muscle she was working so hard to build was not showing up the way she expected.

She was gaining fat around her waist despite all the training.

Her hair had started thinning too.

Her skin was breaking out and reacting more than usual.

So she did what many people do when progress does not come. She assumed she needed to push harder: more training, more control, more discipline.

When I looked at her week as a whole, a different pattern emerged.

It looked like pressure, too little sleep, too much intensity, too much screen exposure.

Not enough morning light, not enough recovery, not enough connection.

A lot of pressure to keep performing.

None of these things were her nutrition. But all of them were shaping the conditions in which her body was receiving it.

Training to build muscle is important. But training inside a body that is sleeping five hours, missing recovery, living under pressure, and rarely receiving natural light is not received the same way.

The same input can lead to very different outcomes, depending on the body receiving it.

In her case, the issue was not willpower.

The issue was that the strongest signals in her life were not supporting the result she wanted.

So I did not ask her to change her nutrition or to stop training. She was not ready to train less than once a day, and I respected that.

But I did ask her to stop treating recovery as optional.

We started with two things.

Go to bed thirty minutes earlier each week, gradually, until she was consistently asleep around 11:30 p.m. Nothing more extreme than that. It had to be something she could actually do.

And in the morning, before anything else, go outside.

Not to train but to see the sky. And on some mornings, that walk replaced the indoor cardio session, until her body was in a better position to handle more intensity again.

That was it.

No new protocol, no elimination, no supplement overhaul.

Thirty minutes more sleep + morning light before a screen.

Within a few weeks of consistency, something started to shift.

Her energy became more stable.

Recovery from training improved.

The dark circles under her eyes started to fade. Her skin color and texture began to improve.

The constant feeling of running on empty started to soften.

And once her system had a little more capacity, other changes became easier.

Training once a day became more realistic and there was more room for connection and rest stopped feeling like such a threat.

The food had not changed, but the body receiving the food had.

A few months later, she made a decision on her own. She reduced her training from seven days a week to five, adding two active recovery days where she prioritized time with other people.

Around that time, something else shifted. The fat around her waist began to decrease. Her waist started to come back.

Not because she trained harder, but because her body was finally receiving a different set of signals.

This is the pattern I want you to notice.

When progress stalls, many people increase effort.

Not losing weight? Train more.

Not sleeping? Push through.

Not building muscle? Add another session.

Digestive symptoms? Restrict more foods.

Fatigued? Add more rules.

But sometimes more effort amplifies the very signal the body is already responding to.

Sometimes the next step is not doing more, it is changing the signal.

The question is whether we are looking at the right signals, because the body is always responding.

The Pattern

When progress stalls, our instinct is often to increase the very signal that is keeping us stuck.

The Question

What is your body actually responding to?

This Week’s Observation

Before changing your nutrition, training, or supplements this week, pause and ask yourself:

Am I responding to my body or reacting to my frustration?

What signal is my body actually responding to right now?

And it is an important question. After eight years working with people on the Paleolithic Ketogenic Diet, I have seen nutrition change lives in ways that nothing else could. People recovering from conditions they were told were permanent. Bodies doing things that medicine had stopped expecting.

I believe in the power of food deeply. That has not changed.

But there was a period of my own life that forced me to ask a different question entirely.

I was living in a large city. Constant noise, pollution, artificial light at every hour. And I was in a relationship that was causing me a level of stress I had never experienced before.

My nutrition was not the problem.

I was eating well. I knew what I was doing. I had been working in this space for years. And yet my body started doing things I could not explain through food alone.

First the sleep went. Then everything that depends on sleep started to follow.

My skin began reacting - red, itchy patches that appeared without warning. My scalp. My breathing. I started having asthma attacks. I had never had asthma in my life. Every time I walked into an Uber, the perfume inside gave me a migraine so strong I had to vomit. I was reacting to everything — smells, cleaning products, things that should have been completely irrelevant to my body.

I felt emaciated from the inside. Like my system had run out of resources to cope.

I went to an allergy doctor. Tests came back. I was diagnosed with mast cell activation syndrome.

At that point, I was not reacting to a food. I was reacting to life itself.

That was the moment I understood something I could not unfeel.

The missing piece was not another diet adjustment. It was the state of the body receiving the diet.

I had been giving my body excellent inputs while the environment around those inputs — the relationship, the city, the chronic low-grade alarm I was living in — was working against everything I was trying to do. My threshold had dropped so low that my system could no longer tolerate anything. The food was not the problem. The conditions receiving the food were.

I spent the years that followed going very deep into what I had been missing. Not abandoning nutrition — it remains one of the most powerful things I know. But trying to understand why the same approach could produce such different results in different people. Why someone could do everything correctly and still feel like their body wasn’t getting the message.

What I kept coming back to was this.

The body doesn’t just respond to what you give it. It responds to what it is able to do with what you give it. And that depends on so much more than the food on the plate.

It depends on how you sleep. On what you carry emotionally every day. On the environment you live in, the relationships you stay in, the state your nervous system is actually in while you follow the protocol. Two people can do the same thing and get completely different results — not because one is doing it wrong, but because the body receiving the protocol is not the same.

I had been seeing this pattern in my work for years. But living it myself made it impossible to explain away.

What is my body actually responding to?

That question changed everything for me.

Because once I stopped looking only at food, I started seeing what my body had been responding to all along.

The body is always responding.

Not only to what we eat.

To how we sleep.

To the environment we live in.

To the relationships we stay in.

To the rhythms we keep.

To the emotional weight we carry.

To the life we are actually living.

And sometimes the next step is not a new protocol.

Sometimes it is seeing the full picture for the first time.

If this resonates, I would love to hear from you. Hit reply and tell me what came to mind. I read everything.

“Is eating this much fat actually safe?”

It’s a fair question.

For decades, dietary guidelines have warned against high fat intake, especially saturated fat, based on its presumed link to cardiovascular disease.

But the current scientific landscape is more nuanced than that.

The Problem With The “High Fat = Dangerous” Narrative

The idea that saturated fat directly causes heart disease has been increasingly challenged over the last decade.

Several large meta-analyses, including those by Rajiv Chowdhury (2014) and Siri-Tarino (2010), found no consistent evidence that saturated fat intake alone is independently associated with increased cardiovascular risk.

Similarly, analyses published in journals such as The BMJ and The American Journal of Clinical Nutrition have emphasized that dietary patterns and metabolic context matter more than isolated nutrients.

This doesn’t mean that everything is safe.

It means that fat, by itself, is not the full story.

Context Is Everything

One of the biggest mistakes is evaluating fat without considering the environment it’s consumed in.

A diet that combines:

• high fat
• high refined carbohydrates
• ultra-processed foods

produces a very different physiological response than a diet that is:

• low in carbohydrates
• based on whole, unprocessed foods
• metabolically stable

The body doesn’t respond to nutrients in isolation.

It responds to patterns.

What Happens In A Ketogenic State

When carbohydrate intake is low and fat intake is higher, the body shifts toward:

• increased fat oxidation
• ketone production
• reduced reliance on glucose

This metabolic state is well documented.

Clinical research, particularly in epilepsy and metabolic disorders, has shown that ketogenic diets can:

• improve glycemic control
• lower circulating insulin
• provide an alternative fuel source for the brain

This does not mean ketogenic diets are universally appropriate.

But it does demonstrate that fat-based metabolism is a normal physiological adaptation.

What About Cholesterol?

This is where most concerns arise.

On a ketogenic diet, lipid markers often change:

• LDL cholesterol may increase
• HDL cholesterol often increases
• triglycerides tend to decrease

But interpreting these changes requires context.

Cholesterol Is Not Just a “Risk Marker”

Cholesterol plays essential roles in:

• hormone synthesis
• cell membrane structure
• neurological function

Looking Beyond LDL Alone

More recent approaches in metabolic health emphasize that isolated markers don’t tell the full story.

Instead, clinicians often look at patterns such as:

• triglyceride to HDL ratio
• fasting insulin levels
• markers of inflammation
• overall metabolic health

Why Inflammation Matters

Chronic, low-grade inflammation is increasingly recognized as a key driver of cardiovascular disease.

Factors that influence inflammation include:

• dietary quality
• insulin resistance
• visceral fat
• lifestyle factors

A diet that improves metabolic stability may also influence inflammatory processes, which is why looking at cholesterol alone is often insufficient.

Why PKD Is Different From “High-Fat Diets”

Not all high-fat diets are the same.

PKD is not:

• a processed “keto” diet
• a high-fat + high-carb combination
• a diet built around snacks or substitutes

It is a structured therapeutic approach based on:

• whole, unprocessed animal foods
• natural animal fats
• exclusion of vegetable oils, nuts, seeds, and dairy
• inclusion of organ meats for nutrient density

Continue reading to understand why food quality and structure matter more than fat intake alone and how this changes the way high-fat diets should be evaluated.

the next question becomes very practical:

What does a correct meal actually look like?

Because this is where most people start guessing.

And guessing is what creates inconsistency.

The Real Goal Is Not Just “Eating PKD”. It’s Maintaining Therapeutic Ketosis

This is the most important shift to understand.

You’re not just following a list of foods.

You’re creating a metabolic state.

Therapeutic ketosis.

And everything – food choices, fat intake, meal size – revolves around that.

Why This Changes How You Structure Your Meals

Because there isn’t one fixed way to eat.

There is a starting structure…

and then there is adjustment based on your response.

The Starting Point (The Famous PKD Ratio)

A commonly used starting point is:

100 grams of lean meat : 35 grams of added fat.

This gives you a structure.

A reference.

A place to begin.

But this is not the end point.

Why The Ratio Is Not Fixed

Because not everyone enters or maintains therapeutic ketosis in the same way.

Each individual differs in:

• metabolic flexibility
• level of inflammation
• digestive capacity
• activity level
• overall health state

Which means:

• some people need more fat
• some need slightly less
• some need to adjust meal size
• some need time before things stabilize

Continue reading to understand how to adjust this in practice and what to look for in your own body.

How do I know if I’m actually doing this correctly?

Because on paper, it seems simple.

Animal foods.
High fat.
Structured.

But in practice, there are a few key markers that tell you whether the approach is truly working for your body.

It’s Not Just About “Following the Rules”

You can technically follow a food list and still not get the outcome you expect.

Because what matters is not only what you eat, but the state your body shifts into as a result.

The Core Goal: A Stable Metabolic State

At its core, PKD is designed to support a metabolic environment where:

• fat is the primary fuel
• blood glucose remains relatively stable
• insulin demand is reduced

This is what allows the body to operate in a more consistent and less reactive way.

So What Should You Look For?

In a nutshell:

directional signs that your body is adapting.

1. More Stable Energy Throughout the Day

One of the first things many people notice is a shift in energy.

Instead of:

• highs and crashes
• needing frequent snacks
• feeling driven by hunger

Energy becomes more steady.

This reflects a transition toward greater reliance on fat as fuel, a more stable energy source, especially in a system that has been relying heavily on glucose fluctuations.

2. Reduced Hunger and Fewer Cravings

As the body adapts, appetite often becomes more regulated.

This is often the result of:

• reduced blood sugar fluctuations
• more satiating meals
• fat providing longer-lasting energy

3. Digestion Becomes Simpler (Over Time)

This one is important to understand properly.

At the beginning, digestion can fluctuate.

Some people experience constipation.
Others may experience looser stools.

Both can happen during the adaptation phase.

But over time, many people notice:

• less bloating
• more predictable bowel movements
• fewer digestive reactions

Because the diet reduces complexity and removes many common dietary irritants.

And when things are set up properly, both extremes tend to settle.

Constipation often improves as fat intake and hydration are adjusted.

Loose stools often stabilize by adjusting fat sources and as digestion adapts to higher fat intake and simpler food combinations.

4. Mental Clarity and Focus

This is a big one for most people.

• clearer thinking
• more stable mood
• less mental noise or fog

This is often associated with more stable glucose supply and the presence of ketones as an alternative fuel for the brain.

5. A More Predictable Internal Response

This is one of the most overlooked markers.

When PKD is applied correctly, the body often feels:

• more stable
• less reactive
• more predictable day to day

Creating a more consistent environment.

What This Doesn’t Mean

It doesn’t mean:

• no symptoms ever
• no adaptation phase
• no fluctuations

And it definitely doesn’t mean that everything changes overnight.

When Something Feels Off

If you’re not experiencing any of these shifts over time, it’s worth looking at:

• fat intake (often too low or too high)
• inclusion of foods outside PKD
• consistency
• overall structure

Usually, small adjustments make a big difference.

A More Accurate Way To Think About It

Instead of asking:

“Am I doing this perfectly?”

Ask:

“Is my body becoming more stable over time?”

Because that’s the direction you’re looking for.

Final Thought

PKD is simple, but it’s not random. It follows clear physiological principles.

When applied correctly, the body tends to move toward:

• more stability
• more predictability
• more efficient energy use

And those are the signals you want to pay attention to.

If you want a clear structure to follow without guessing, I break this down step by step inside my PKD guide.

How your body responds to your internal state.

How regulation happens.

How identity shapes your experience.

In many ways, everything we’ve been exploring is somatic work, not something you think your way through, but something your body experiences and learns through.

And if you’ve really taken that in… something shifts.

You start seeing that it’s not just about what you do.

It’s about how you live.

So at this point, a question naturally comes up:

If all of this matters… where does food fit in?

This Is Where People Get Confused

Because they start swinging to the other extreme.

They think:

“Maybe food isn’t that important.”
“Maybe it’s all about the nervous system.”

But that’s not what this is about.

Food Is Still One of the Strongest Signals You Give Your Body

Every time you eat, you’re sending information about:

• energy availability
• metabolic state
• inflammatory load
• digestive demand

And your body responds to that immediately.

What Changes Is Not The Importance of Food, It’s How You Use It

Before, you might have approached food like this:

trying to control everything through diet

Now, the shift is:

using food as a clear, consistent input within a bigger system

Why PKD Works So Well In This Context

Because it simplifies things. It removes noise.

It gives the body:

• predictable inputs
• stable energy
• less digestive complexity

Continue reading to see what this actually looks like in your day-to-day, and how to apply it without overcomplicating things.

there are certain patterns that show up again and again.

Not because people are doing something “wrong.”

But because a few key details are often misunderstood or overlooked.

And once those are clear, everything becomes much more straightforward.

Mistake #1 – Eating Too Lean

This is by far the most common one.

People think:

“I’m eating meat, so I’m doing it right.”

But PKD is not a high-protein diet.

It’s a fat-based approach.

When meals are too lean:

• energy drops
• hunger increases
• results feel inconsistent

The fix:

Focus on fatty cuts of ruminant meat.

And don’t be afraid to add fat when needed
(suet, marrow, tallow).

This is not optional.

This is part of what makes the diet work.

Mistake #2 – Adding Foods That Don’t Belong

This usually comes from mixing approaches.

Things like:

• butter or ghee
• dairy products
• nuts and seeds
• keto snacks

They might seem small.

But they’re not, because they change the environment you’re trying to create.

The fix:

If you’re doing PKD…

do PKD.

Keep it clean.
Keep it simple.
Keep it consistent.

Mistake #3 – Treating Organs as Optional

A lot of people avoid liver.

Or include it occasionally and think that’s enough.

Organs are not a side detail in this approach.

They are part of the foundation, especially during periods of healing, when the body requires more nutrient-dense support.

The fix:

Include liver regularly.

Mistake #4 – Overcomplicating Something That Works Because It’s Simple

This one happens without people realizing it.

They start adding:

• more recipes
• more combinations
• more variation

And slowly…

they move away from what makes PKD effective in the first place.

The fix:

Come back to basics.

Simple meals.
Repeatable structure.

You need consistency.

Mistake #5 – Expecting Instant Results

This is where frustration usually comes in.

People expect:

• immediate changes
• perfect consistency
• fast transformation

And when that doesn’t happen…

they start questioning everything.

But the body needs time to adapt.

The fix:

Stay consistent.

Let the process unfold.

Don’t interrupt something that hasn’t had the chance to fully work yet.

The Bigger Picture

When PKD is applied correctly, it’s not confusing.

It’s actually very clear.

Most of the issues I see don’t come from the diet itself.

They come from how it’s implemented.

Small details.

But they matter.

If you want a clear, step-by-step structure so you don’t have to guess your way through this, I break it all down inside my PKD guide.

You’ve been introduced to a different way of understanding your body as a system that responds to the signals it receives.

You’ve learned that regulation doesn’t happen in isolated practices.

It happens in real life.

In the small moments.
In the boring moments.
In the frustrating moments.

And this is exactly where most people disconnect.

Why You Might Feel Like Nothing Is Working

Because you’re still treating this as something you do, instead of something you are.

Because you’re still waiting to feel different before you become different.

You read.
You understand.
You agree.

But when life happens…

You react the same way.

And then the mind says:

“I’m not healing”
“This isn’t working”
“Maybe I need something else”

No.

You don’t need something else.

You need to decide who you are.

The Real Reason People Stay Stuck

It’s not lack of knowledge and definitely not lack of tools.

It’s that your identity hasn’t changed.

You can have the best strategy in the world…

But if you still see yourself as:

• someone who is easily overwhelmed
• someone whose body is fragile
• someone who “tries but doesn’t get results”

Your system will keep organizing around that and will keep proving that to you.

Because the body doesn’t follow what you want.

It follows what you believe is true about yourself.

This Is Where Everything Shifts

Let’s make this practical.

What does this actually look like day to day?

The structure itself is very simple.

Animal foods.
High fat.
Structured.

But in real life, this is where most people get confused.

The Foundation

At its core, the Paleolithic Ketogenic Diet is a therapeutic nutritional approach used by the ICMNI-Paleomedicina clinic in the nutritional management of patients with chronic diseases. It is designed to induce and maintain stable ketosis.

Not as a trend.

But as a tool.

The aim is not ketosis for its own sake, but the metabolic environment that ketosis helps create.

In practice, this includes:

• more stable energy
• reduced inflammatory burden
• improved mental clarity for many people
• a calmer internal environment during periods of healing

Another central idea behind PKD is reducing the number of variables the body has to deal with during recovery.

Instead of combining many different foods, the approach focuses on highly nourishing, well-tolerated animal foods that provide what the body needs in a more direct and consistent way.

This often allows the system to settle, not because food is being restricted for the sake of it, but because unnecessary complexity is removed.

What That Means on Your Plate

This is where many people get it wrong.

A typical meal is not:

• steak with butter
• chicken breast with egg whites

Instead, it looks more like:

• fatty cuts of ruminant meat
• additional animal fat when needed, such as suet, tallow, or marrow
• organs included regularly
• eggs, if tolerated

The goal is not just to eat animal foods.

It’s to eat them in a way that supports stable therapeutic ketosis, nutrient density, and reduced dietary irritation.

Organs Are Foundational

This is one of the most important pieces.

Organs, especially liver, are not optional extras.

They are a key part of the approach.

Foods like liver provide:

• highly bioavailable vitamins
• essential nutrients in forms the body can easily use
• additional nutritional support during recovery

During healing, the body often needs more support, not less.

And this is where real food plays a central role.

Why Supplements Are Not the Focus

This approach prioritizes nutrient density through food, not supplementation.

When the diet is properly structured, the nutrients the body needs are already present in:

• meat
• fat
• organs

This reduces the need to rely on external inputs and helps keep the system more stable and predictable.

The focus is not on adding more.

It’s on getting the fundamentals right first.

What’s Excluded

To create that stability, certain foods are removed:

• cereals and grains
• beans and legumes
• all dairy products, including butter and ghee
• vegetable oils
• nuts and seeds
• sugar
• additives and chemicals
• alcohol

This is not about restriction for its own sake.

It’s about reducing potential sources of irritation and variability while the body is trying to recover.

Two Versions of the Diet

It’s important to understand that there isn’t only one way this is applied.

There is:

a stricter therapeutic version
and a more flexible version used later on

The strict version removes all plant foods and is typically used when deeper healing is needed.

Over time, some people are able to reintroduce:

• some vegetables
• small amounts of fruit
• even honey in some cases

This depends entirely on the individual.

The key is that flexibility comes after stability.

There Is No Fixed Amount

Another common misconception is that this diet follows rigid numbers.

It doesn’t.

The goal is to maintain a stable internal state, including stable ketosis for those using it therapeutically.

This means:

• food quantity may vary
• fat ratios may shift
• meals may adjust over time

based on how the individual responds.

Final Thought

It’s easy to overcomplicate this.

But in practice, the strength of this approach is in its simplicity.

Consistent inputs.
Nutrient-dense foods.
Reduced variability.

That’s what allows the body to settle.

If you want a deeper, step-by-step breakdown, I explain the full structure inside my PKD guide.

“What’s causing this?”

Food.
Supplements.
Triggers.
Protocols.

And for a while, that makes sense.

Because sometimes removing the right input is enough to create a big shift.

But there’s another layer that becomes relevant once you’re no longer at the beginning.

And it’s this:

What your system is organizing your life around.

Not what you’re eating, but what has become the center of your attention, decisions, and identity!

Read more

And it makes sense.

From the outside, both center around animal foods and remove most of what people associate with a “modern diet.”

But once you look closer, the differences start to matter, especially if you’re trying to understand why something is or isn’t working for you.

Carnivore: Simple, but Not Always Consistent

The carnivore diet is an animal-based elimination approach.

By removing plant foods, many people experience:

• less digestive discomfort
• fewer inflammatory symptoms
• more stable energy

For some, this alone is enough.

But carnivore is not a tightly defined framework.

Two people can both follow a “carnivore diet” while eating in very different ways: different fat levels, different food choices, different structures.

While some people feel great, others reach a point where things stop improving.

When “Animal-Based” Isn’t Enough

A pattern that shows up quite often is this:

Someone starts carnivore, feels better at first…
and then progress slows down (I experienced this myself when I first started carnivore in 2017).

Not in every case, but often enough to notice.

Without a clear approach to things like fat intake, food choices, or consistency, the body may not fully settle into a stable state.

Structure becomes important, especially when using diet as a tool for healing.

Where PKD Differs

The Paleolithic Ketogenic Diet is also based on animal foods.

But instead of being open-ended, it follows a more defined structure.

It focuses on:

• a specific fat-to-protein ratio
• prioritizing certain types of foods
• creating a more stable metabolic environment

Rather than relying on intuition alone, it provides a clearer framework.

One of the aims is to maintain a more consistent internal state, including ketosis as part of that process.

Not because ketosis is necessary for everyone, but because in certain contexts, it can make a meaningful difference.

PKD is a therapeutic dietary approach developed by the ICMNI-Paleomedicina and has been used in clinical settings for more than a decade.

Two Different Tools

It’s easy to turn this into a question of which diet is “better.”

But that misses the point.

Carnivore simplifies.

PKD structures.

For some people, simplicity is enough.

For others, a more defined approach makes a noticeable difference.

What Comes Next

Once you see this difference, a more important question naturally comes up:

What does PKD actually look like in practice?

We’ll go into that in the next article.

If you want to explore this approach in more detail, I’ve put together a free PKD guide where I walk through the structure and practical steps.

Not through logic.

If the body repeatedly receives signals that suggest unpredictability, urgency, or danger, it stays in protection mode.

If it repeatedly receives signals of stability and safety, it begins to relax.

In practice, four signals consistently help shift that state.

And once you start recognizing them, you begin to understand why many people remain stuck even while doing everything “right.”

It isn’t.

Both diets can produce ketosis, but they approach it in very different ways, and those differences matter when the goal is healing, not just weight loss.

Understanding this distinction can completely change how people think about ketogenic diets.

The Origins of the Ketogenic Diet

The classical ketogenic diet was originally developed in the 1920s to help manage epilepsy in children.

The idea was straightforward: reduce carbohydrates drastically and increase fat intake so the body produces ketones for fuel.

Over time, the diet expanded beyond its original medical use and became popular for weight loss and metabolic health.

Today there are many variations:

• standard keto
• dirty keto
• high-protein keto
• plant-based keto

Despite these differences, most versions share one principle:

As long as carbohydrates are low enough, almost any food can fit.

This is where the Paleolithic Ketogenic Diet takes a very different approach.

PKD Starts With a Different Question

The Paleolithic Ketogenic Diet (PKD) was developed with a different starting point:

What foods best match human evolutionary physiology?

Instead of focusing only on macronutrients, PKD looks at which foods allow the body to function and repair optimally.

The diet therefore emphasizes nutrient-dense animal foods such as:

• ruminant meat
• animal fat
• organs
• eggs (when tolerated)

Plant foods, dairy, seed oils, and processed foods are typically removed during the initial healing phase.

Not simply because of carbohydrate content, but because these foods may influence inflammation, immune activity, and gut integrity in sensitive individuals.

The Role of the Gut

One of the central ideas behind PKD is the restoration of the intestinal barrier.

Research and clinical observations suggest that increased intestinal permeability (sometimes referred to as “leaky gut”) may contribute to chronic inflammation and autoimmune conditions.

The PKD approach removes foods that can irritate the gut lining while providing highly bioavailable nutrients from animal sources.

This differs from many ketogenic diets, where foods like dairy, nuts, seed oils, and large amounts of vegetables are often included.

For some people these foods are well tolerated.

For others, they may continue to irritate the gut and immune system.

Ketosis Is Not the Only Goal

Both keto and PKD can produce ketosis.

But ketosis alone is not the primary objective of PKD.

The focus is on nutrient density, evolutionary compatibility, and metabolic stability.

Many modern keto diets rely heavily on foods such as:

• cheese
• cream
• nuts
• keto desserts
• processed low-carb products

While these foods can maintain ketosis, they don’t necessarily provide the nutrient profile required for optimal physiological function.

PKD places much more emphasis on whole animal foods, including organs, which supply vitamins and minerals that are difficult to obtain from muscle meat alone.

PKD Is Not Always Meant to Stay Strict Forever

Another point that is often misunderstood is that the strict version of PKD is usually used as a therapeutic phase.

During this period, the goal is to stabilize metabolism, reduce inflammation, and allow the gut to repair.

Once the body improves and symptoms stabilize, many people are able to gradually reintroduce certain foods.

Depending on the individual, this may include:

• specific vegetables
• certain fruits
• honey

Not everyone will tolerate the same foods, and the process needs to be individualized.

For many people, the goal is not lifelong restriction, it is restoring enough metabolic and digestive stability that the body can tolerate a wider variety of foods again.

The Bigger Picture

Diet alone rarely explains every health symptom.

The nervous system, stress levels, sleep, and environment also play important roles.

But food remains one of the strongest signals the body receives every day.

And when the goal is healing, not just ketosis, the details of that signal matter.

Over the years working with clients, I’ve seen how confusing the ketogenic landscape can be.

Many people assume all ketogenic diets are the same.

They’re not.

Understanding the difference can help people make more informed decisions about their health.

If you heard a noise in the bushes and didn’t investigate, you might miss a predator.

If you ate something unfamiliar and didn’t monitor how your body reacted, you might poison yourself.

From an evolutionary perspective, the safest strategy was simple:

Notice sensations early.
Investigate quickly.
Resolve uncertainty.

That system helped humans survive.

But in the context of modern health symptoms, the same mechanism can start working against us.

Because the brain still treats uncertainty as something that must be solved immediately.

The Nervous System’s Job Is Prediction

Your nervous system is constantly predicting what sensations mean.

Is this safe?
Is this dangerous?
Should we mobilize resources?

When something unusual happens in the body (bloating, fatigue, a headache) the brain immediately tries to identify the cause.

That’s normal.

But when symptoms are fluctuating and inconsistent, the brain often cannot resolve the uncertainty quickly.

And when uncertainty remains unresolved, vigilance increases.

This is where many people unknowingly enter a loop.

The Reassurance Loop

When a sensation appears, the brain wants certainty.

So it starts searching.

You might:

• replay what you ate earlier
• analyze how your stomach feels
• google the symptom
• read about possible causes
• scroll through forums
• check your body repeatedly

Each of these behaviors feels logical.

But from the nervous system’s perspective, they communicate something very specific:

“This situation requires attention.”

The brain then allocates more resources to monitoring the body.

And the more something is monitored, the more noticeable it becomes.

If you recognize yourself in this pattern, the rest of this article explores:

• why reassurance-seeking amplifies symptom perception
• the evolutionary reason the brain gets stuck in this loop
• and practical ways to interrupt it without ignoring your body

A meal feels fine one day.
The next time, it doesn’t.

A food that seemed safe suddenly causes a reaction.

Digestion improves for a week… and then something shifts again.

When this happens repeatedly, most people come to the same conclusion:

“My body is inconsistent.”

But in many cases, the body is not actually behaving randomly.

It’s responding to variables we don’t usually think to look at.

The Body Is Context-Sensitive

But this is where the misunderstanding usually begins.

We tend to evaluate symptoms in isolation.

We ask:

What did I eat?
What supplement did I take?
What changed in my diet?

But the body doesn’t operate in isolation.

The nervous system, which constantly regulates digestion, inflammation, immune activity, and metabolic processes, is influenced by context.

That context includes things like:

• perceived safety
• mental load
• sleep quality
• emotional pressure
• constant monitoring of symptoms

When those variables shift, the body’s internal environment shifts with them.

And that can influence how the same food or stimulus is tolerated.

Why This Is Often Misinterpreted

When symptoms fluctuate, the instinct is to tighten control.

People start:

• restricting foods
• changing protocols
• researching new explanations
• analyzing every sensation

All of that is understandable.

But ironically, this constant monitoring can increase internal pressure.

The nervous system becomes more vigilant.

Increased vigilance can make symptoms feel more reactive.

Not because the body is fragile.

But because the system is staying in a more alert mode.

A Small Pattern Most People Miss

Once you see this pattern, it’s hard to unsee it.

There’s something I’ve noticed repeatedly over the years.

Many people feel better in situations where they are not trying to fix their body.

Travel.
Social time.
Days where attention shifts away from symptoms.

The diet might not even be perfect.

But something else changes.

There’s less preparation.
Less monitoring.
Less pressure to get everything right.

And the body often responds to that.

The Important Distinction

This doesn’t mean symptoms are “all in your head.”

Physiology matters.

Food quality matters.

Underlying conditions matter.

But the internal state of the nervous system also shapes how the body responds moment to moment.

That layer is often overlooked because it’s subtle.

Yet it can explain why the same input sometimes produces a different output.

A Small Experiment

If symptoms often feel unpredictable, try observing something different this week.

Instead of focusing only on what you ate, also notice:

What state were you in when you ate it?

• Were you relaxed?

• Rushed?

• Monitoring your body?

• Thinking about symptoms?

• Scrolling on your phone?

You might begin to notice patterns that weren’t obvious before.

Why This Matters

When we believe the body is random, we tend to control more.

More restriction.
More protocols.
More analysis.

But when patterns become visible, the approach can shift.

Sometimes the most useful change is not another adjustment to food.

It’s changing the environment the body is operating in.

If you’ve been stuck in the loop of trying to fix every symptom, you’re not alone.

I’ve watched this pattern repeat for years and when people finally see it clearly, something shifts.

Because they stop reinforcing urgency.

In the paid series, I’m breaking down the exact patterns that keep the nervous system in protection mode and the simple shifts that help it move out of it.

It’s not when symptoms disappear.

It’s the day you realize you don’t have to fix every fluctuation.

Over the past decade working one-on-one with clients, and through my own lived experience, I’ve watched the same pattern repeat.

Different diagnoses.
Different diets.
Different lab results.

The symptoms vary.

The loop does not.

This isn’t theory. I’m saying this from lived experience and from observing this same nervous-system pattern in well over a thousand one-on-one clients across the past decade.

Most people don’t need another protocol, they need to stop reinforcing urgency.

The Loop That Quietly Maintains Sensitivity

Let’s make this very clear.

When a symptom appears, three things happen:

1. A sensation arises.

2. The brain interprets it.

3. You respond.

Most people focus on the sensation.

But what keeps sensitivity alive long-term is the response.

Here’s the common pattern:

Symptom → Alarm → Immediate Fixing → Monitoring → Temporary Relief → Reinforced Alarm Pathway

The nervous system learns through repetition.

If every sensation is followed by urgency, the brain strengthens the association:

“This requires mobilization.”

Mobilization means sympathetic activation, the body’s alert mode.

In that state:

• Cortisol shifts.

• Heart rate variability drops.

• Digestive coordination tightens.

• Immune signaling becomes more reactive.

Why? Simply because your system believes it needs to prepare.

Now compare that to this:

Symptom → Pause → No Immediate Escalation → Updated Prediction

Same symptom.

Different response.

This is where recalibration begins.

Someone struggles with digestion.
Food sensitivities.
Sleep.
Inflammation.
Symptoms that feel unpredictable.

Then they go on vacation.

And something shifts.

They tolerate foods they normally react to.
Their stomach feels calmer.
Sleep improves.
The body feels lighter.

The diet didn’t radically change.

But the experience did.

And that difference matters.

The Confusion That Follows

When this happens, people rarely feel relieved.

They feel confused.

“If I can eat this here… what does that mean?”
“Was the food actually the problem?”

The mind wants a simple explanation.

This isn’t randomness, it’s context.

The Body Doesn’t Digest in Isolation

Digestion isn’t just about what you eat.

It’s about the state you’re in when you eat.

The autonomic nervous system (the system that automatically shifts you between “alert mode” and “rest-and-digest mode”) regulates:

• stomach acid
• digestive enzymes
• bile flow
• gut motility
• immune signaling in the gut

When sympathetic activation (the body’s alert mode) is dominant, digestion becomes less coordinated and sometimes more reactive.

When parasympathetic tone (rest-and-digest mode) is more present, digestion functions more efficiently.

This isn’t abstract.

Research shows chronic stress can alter cortisol rhythms, influence vagal tone, and affect gut permeability and immune signaling. The body quite literally processes food differently depending on perceived safety.

On vacation, urgency often decreases.

Not because everything is perfect, bu because pressure softens.

It’s Not the Beach

The improvement isn’t about palm trees or hotel breakfasts.

It’s about reduced vigilance.

You’re not optimizing every input.
You’re not adjusting protocols.
You’re not evaluating each sensation immediately.
You’re not trying to get somewhere.

You’re simply living the day.

And your nervous system responds to that.

The Subtle Variable

The real shift is usually this:

Less preparation.

Less background monitoring.

Less “stay ahead of symptoms.”

For many people, that low-grade preparation has been running constantly.

Vacation interrupts it.

And the body gets a temporary window of non-urgency.

That alone can shift tolerance.

Not permanently, but noticeably, and that’s information.

The Wrong Takeaway

It’s easy to conclude:

“I need to recreate the vacation diet.”
“I need to change my environment.”
“I need to escape more often.”

But if symptoms shift with state, the lever isn’t only the food.

It’s the context around it.

And that’s a much more powerful place to look at.

A Small Experiment

You don’t need to leave your life, but you can experiment with reducing preparation inside it.

This week:

• Have one meal where you deliberately don’t evaluate how it felt afterward.

• Choose one evening without health research, symptom analysis, or protocol adjustments.

• Start one morning without scanning your body for symptoms before getting on with your day.

Not suppressing.
Not pretending symptoms don’t exist.

Simply not preparing in advance.

You may notice something subtle.

Less bracing.
More neutrality.

And neutrality is often how safety feels.

Where People Get Stuck

Most people understand this intellectually.

They know stress affects digestion.
They know the nervous system plays a role.

But when symptoms flare, the instinct to control returns.

Research.
Restriction.
Adjustment.
Preparation.

And that’s the moment urgency quietly rebuilds itself.

Reducing urgency on easy days is manageable.

Reducing it on difficult days, when you feel uncertain and uncomfortable, is different.

That’s where patterns actually change.

Because regulation doesn’t solidify when everything is calm.

It stabilizes when discomfort appears and you respond differently.

That skill does not develop automatically.

It’s practiced.

Slowly.

Repeatedly.

In the paid articles, we’re working much more directly with how urgency leaves the body, especially on the hard days when your old reflex wants to take over.

Because the goal isn’t to only feel better when you escape your life.

It’s to build a system that doesn’t require escape to function well.

Sometimes the biggest shift isn’t what you ate.

It’s the state you were in when you ate it.

— Natalie

Urgency softens.

And instead of feeling relief…

you feel nothing special.

No breakthrough.
No visible shift.
No dramatic improvement.

Just less tension.

Less scanning.

Less internal pressure.

And because it doesn’t feel like progress, many people assume: “this isn’t working.”

That assumption is where regulation quietly gets undone.

The Mistake Most People Make

We’ve been conditioned to associate intensity with change.

Stronger protocol = better outcome.
Bigger emotional release = breakthrough.
More effort = more progress.

So when nervous system work produces something subtle, like neutrality, the brain doesn’t categorize it as improvement.

It categorizes it as:

Flat.
Boring.
Uncertain.

But biologically, neutrality often means something profound:

The alarm system is no longer driving the body.

In autonomic terms, sympathetic activation (the body’s alert or fight-or-flight mode) is no longer dominant. The parasympathetic branch (rest-and-digest mode) is stabilizing enough to hold the system without urgency.

Not euphoric, but stable.

And stability is quiet.

The Adrenaline You Didn’t Realize You Were Using

Here’s the shift that changes how you see healing:

For many people, urgency has been the fuel.

It fuels research.
It fuels discipline.
It fuels protocol precision.
It fuels hyper-awareness.

It also fuels identity.

When urgency softens, that fuel disappears.

And without that edge of activation, the system can feel:

Less driven.
Less sharp.
Less intense.

That is not regression.

That is the absence of adrenaline.

Most people don’t realize how much of their “productivity” was actually low-grade sympathetic activation.

When that reduces, the body begins reallocating energy toward repair.

But because repair is slower and less stimulating than vigilance, it can feel like stagnation.

This is the turning point.

If this is starting to shift how you see your own process, it’s important not to stop here.

Because this is the point where many people accidentally restart urgency and undo the safety they’ve been building.

In the rest of this article, we go deeper into:

• why hard days are not setbacks
• how neutrality gets mistaken for stagnation
• what is actually changing biologically when things feel “flat”
• and how to recognize real progress before symptoms fully resolve

This is the part that changes how you respond, not just how you understand.

Sometimes, when you stop trying to control everything…
you don’t immediately feel calmer.

You feel exposed.

You feel uncertain.
You feel like you’ve taken your hands off the wheel.

And that can feel worse before it feels better.

The Reflex Most People Don’t See

If you’ve been dealing with symptoms – digestive issues, food reactions, insomnia, inflammation, anxiety – you’ve probably developed some version of hyper-responsibility.

Monitoring.
Adjusting.
Researching.
Tweaking.
Trying to stay ahead of the next flare.

It makes sense.

When something feels unpredictable, vigilance feels like safety.

But biologically, vigilance keeps the body slightly prepared.

In nervous system physiology, this state is linked to the sympathetic branch – often called the “alert” or “fight-or-flight” system. It doesn’t mean panic. It can be subtle readiness.

And as long as that alert state remains dominant, the parasympathetic branch – the “rest-and-digest” system – doesn’t fully take over.

Digestion, immune repair, and deeper sleep all depend on that shift.

So when you begin reducing vigilance, something interesting happens.

The structure that felt protective starts to loosen.

And your system doesn’t always experience that as relief.

It experiences it as unfamiliar.

Why Non-Linear Healing Is Normal

Many people expect healing to look like steady improvement:

A little better this week.
A little more tolerant next week.
Less symptoms over time.

But nervous systems don’t update in straight lines.

They recalibrate in waves.

Research on stress physiology shows that patterns like cortisol rhythm and vagal tone (a marker of parasympathetic flexibility) don’t shift overnight. They stabilize through repetition – especially repetition of safety cues.

That means difficult days don’t erase progress.

In fact, they often reveal where your system is practicing something new.

The critical variable is not whether symptoms appear.

It’s how you respond when they do.

The Turning Point Most People Miss

Here’s the subtle shift:

When a difficult day happens, the old reflex is:

“What did I do wrong?”
“How do I fix this?”
“Is this a setback?”

Those questions aren’t irrational.

But they signal urgency.

And urgency sustains preparation.

Preparation sustains activation.

Activation limits repair.

The newer response looks different:

“This is uncomfortable.”
Pause.
“I don’t need to solve this immediately.”

That response doesn’t deny symptoms.

It removes panic from around them.

And that removal is biological, not psychological.

When reaction softens, sympathetic tone gradually decreases.
When sympathetic tone decreases, parasympathetic regulation can strengthen.

Not dramatically.

Gradually.

The Paradox of Safety

Here’s the part that confuses most people.

When urgency begins to soften, there is usually no dramatic relief.

There isn’t euphoria.
There isn’t a breakthrough moment.

There is often:

Neutrality.
Ordinariness.
Less bracing.

And because it doesn’t feel like “progress,” people assume nothing is happening.

But biologically, neutrality often means:

The alarm system isn’t scanning.

For systems that have been braced for a long time, that’s significant.

So What Do You Do With a Hard Day?

Not everything.

Not a new protocol.
Not five new supplements.
Not a deep dive into research.

Instead:

• Reduce post-symptom analysis.

• Delay decision-making by a few hours.

• Return to neutral activity.

• Let the body show you what happens without interference.

You’re not suppressing information.

You’re allowing the system to settle before you interpret it.

That alone can change the direction of a flare.

This Is Why Understanding Isn’t Enough

You can intellectually grasp sympathetic and parasympathetic balance.

You can understand polyvagal concepts about safety and social engagement.

But nervous systems don’t recalibrate through insight alone.

They recalibrate through lived experience, especially repeated moments of responding differently on hard days.

Not perfectly.

Differently.

And differently, repeated enough times, becomes the new pattern.

Where We’re Going Next

In the paid series, we’re working more slowly and practically with this.

Not just understanding protection mode, but learning how urgency actually leaves the body over time.

Because removing urgency isn’t about forcing calm.

It’s about reducing the subtle signals that keep the body prepared.

If you feel like you understand the theory but still feel slightly braced…

that’s the work.

And we’re building it step by step over there.

You don’t have to fix everything at once.

Sometimes the shift begins when you simply stop fighting the hard days.
