A Second Look at
Carnivore
A closer look at what underpins the diet.
Carnivore is a powerful dietary framework. It eliminates processed food, seed oils, and refined sugar in one move. That alone puts it ahead of almost any mainstream diet. But the question worth asking is whether that level of restriction actually produces the best possible results, or whether there's a next level that most people are missing.
Strictness Must Justify Itself
Eating only red meat and fat takes real discipline. But that level of restriction only makes sense if it's actually producing something a less restrictive approach can't. What's being left on the table is variety, the enjoyment of eating, flexibility in daily life, and measurable hormonal and physiological benefits that come from healthy sources of carbohydrates. And the outcomes aren't clearly better than what a well-constructed diet built around animal foods, fruit, raw dairy, and honey can produce.
The benefit gap between a strategic natural foods approach and strict carnivore is small. The restriction gap is massive.
What You Sacrifice vs. What You Gain
The Sugar Myth
I used to repeat this one constantly: sugar causes glycation damage, fructose is essentially poison, all of it needs to go. It's one of the most common beliefs in the carnivore world, and the logic sounds convincing on the surface. But when you actually trace the biochemistry, the argument doesn't hold up.
"Fructose is 10x more glycating than glucose."
This is technically true in a test tube. But biology doesn't work in a test tube.
Blood Glucose
Blood Fructose
Fructose circulates in the blood at roughly 1/100th to 1/1000th the concentration of glucose. It's rapidly cleared by the liver. So even if fructose is 10x more reactive per molecule, there are hundreds of times fewer molecules actually present. Per gram consumed, glucose produces more total glycation in the body than fructose does.
Per Molecule
of Glucose
Ketogenic diets elevate methylglyoxal, a compound 20,000x more glycating than glucose per molecule. Sounds terrifying. But methylglyoxal circulates at roughly 1/30,000th to 1/100,000th the concentration of glucose. So the net glycation burden is actually comparable to glucose, not catastrophically worse. The same pattern repeats: a scary number on paper, neutralized by the concentration reality. This is the point. Every mechanism has a counter-mechanism. You can make anything look dangerous or safe depending on which layer you stop at.
What the Ancestral Data Actually Shows
One of the strongest arguments for carnivore is that "our ancestors ate this way." I used to cite this isotopic data all the time as evidence that humans evolved eating only meat. And it's a reasonable starting point. The stable isotope data is real: nitrogen-15 ratios place ancient humans at the trophic level of large predators, suggesting diets composed of 80% or more animal foods. But there's a blind spot in the method that changes the picture significantly.
That's a big deal. It means a population getting 40% of their calories from meat but nearly all their protein from meat would look isotopically identical to one eating 80% meat. So when isotope data gets cited as proof of "hyper-carnivory," it's really just showing where the protein came from. It tells you almost nothing about how much fruit, honey, or starch those people were eating alongside it.
Dental calculus studies confirm this gap. Starch granules from tubers and plant fibers have been found embedded in the teeth of Neanderthals and early modern humans whose isotope profiles appear heavily carnivorous. The plants were there. The isotopes just couldn't see them.
Most of the isotope data that gets cited comes from Ice Age European sites, where plant foods were genuinely scarce. But modeling optimal nutrition off an ice age is like modeling optimal hydration off a drought. Those people were surviving with what they had. Most of human evolution happened in tropical and subtropical Africa, where fruit, honey, tubers, and roots were everywhere year-round. The Hadza, one of the last hunter-gatherer tribes, still get roughly 15% of their calories from honey alone.
A common carnivore argument is that 13,000 years since agriculture is a blink of an eye, not nearly enough time for humans to adapt to carbohydrates. But the genetic evidence says the opposite. Human genes have been selecting for carbohydrate metabolism at an extraordinary pace, and the proof is already in your DNA.
Carbohydrates taste good, and that's not an accident. Salivary amylase starts breaking down starch the moment it hits your tongue. The body is telling you something. Trusting what the body recognizes as nourishing, as long as it's natural whole food, makes more sense than following a framework that says fruit is poison. Fruit, honey, and potatoes aren't modern inventions. They're some of the oldest foods in the human diet.
There's no record of any traditional human society voluntarily eating only meat and fat when other foods were around. Animal foods were always central, and they should be. But every culture that had access to fruit, honey, and roots ate them too. The ancestral model was animal-first, not animal-only.
The Questions Worth Asking
At first, I genuinely bought the individual explanations. Red blood cells live longer on carnivore, so HbA1c rises. Androgen receptors get more sensitive, so you need less testosterone. Each one sounded reasonable on its own. But over time, as I looked harder, I started noticing how many of these explanations there were, and how every single marker that moved in the wrong direction had its own convenient story. At a certain point it starts to feel like grasping at straws, always finding a mechanism to justify the result rather than questioning the diet itself. When you step back and look at all of them together, they paint a pretty clear picture.
None of these individually disqualify carnivore. But when all five point in the same direction, each with its own special explanation, the pattern is hard to ignore. The simplest read is that carnivore is really good, but probably not the final answer. And anyone serious about optimizing owes it to themselves to find out what is.
Carnivore is a massive upgrade from where most people start. It teaches you to prioritize animal protein, cut processed food completely, and take nutrition seriously. But there's a version of this that keeps everything carnivore does right while bringing back what it leaves out. The hormonal support. The variety. The enjoyment.
Required vs. Optimal
A recurring theme in carnivore discussions is that the conversation stays at the level of "what's required" rather than "what's optimal." Both are valid questions. But for anyone pursuing the best possible outcomes, the distinction matters.
Your body adapts to almost anything. That's homeostasis. But adapting and thriving are two different things. Your body will also adapt to sleep deprivation, dehydration, and calorie restriction. "The body adjusted" doesn't mean conditions are ideal. When multiple biomarkers shift in the wrong direction and the only explanation is "you just don't need as much anymore," you have to ask yourself honestly: am I optimizing, or am I just coping?
You can survive on a lot of things. 30g of protein a day will keep you alive. But nobody would call that optimal. The "not required" framing keeps people stuck at the survival level, when what actually matters is performance, hormonal health, and quality of life.
What Carbohydrates Actually Do
A core belief in carnivore circles is that carbohydrates are unnecessary at best and harmful at worst. But the biochemistry of what happens when carbohydrates are present versus absent tells a different story. Adequate carbohydrate intake doesn't just feel better. It drives measurably superior hormonal, metabolic, and neurological function.
The body can absolutely run without dietary carbohydrate. Carnivore proves that. But going from zero carbs to even a moderate intake reduces the rate of gluconeogenesis by roughly 15%, which directly lowers the cortisol demand required to maintain blood sugar. This isn't theoretical. Looking at carnivore blood work, including clients I've worked with personally, elevated cortisol sitting at the high end of the reference range is a consistent pattern. The energy and mental clarity people report on carnivore are real, but it's worth asking how much of that sharpness is adrenaline-driven rather than coming from a fully fueled metabolism.
None of these happen overnight. But cortisol consistently riding the upper end of the reference range creates a compounding hormonal environment that works against the goals most carnivore dieters are actually chasing.
If the goal is actually optimization and not just survival, the markers are observable. Someone with good thyroid function, low stress hormones, and high androgen output looks and feels fundamentally different from someone running on cortisol and adrenaline.

Good Circulation
No 3AM Waking
Androgen Output
No Crashes
These aren't hypothetical. They're the real markers of someone whose thyroid is active, whose cortisol is low, and whose metabolism runs on clean oxidative fuel. Cold hands, waking at 3 AM, low libido, dry skin, thinning hair, needing coffee to function. Those aren't personal failings. They're signs of a metabolism that isn't getting what it needs.
A dense physique, high androgen profile, good skin, full sleep, and genuine vitality don't come from restricting what the body clearly uses well. They come from giving it everything it needs and letting it do what it already knows how to do. Fruit, honey, and well-cooked starches are part of that equation. Removing them doesn't create optimization. It creates a stress response that can feel like it.
Eat Equatorial, Not Local
There's a popular idea in health circles that you should eat seasonally and locally. It sounds right. But think about what that actually looks like if you live in a northern climate: dark winters, limited produce, low variety, and a food environment shaped by scarcity. That's not a model for thriving. It's making do with what's available.
The closer you get to the equator, the more abundance and variety you find. Ripe mangos, papayas, citrus, coconut, honey. These aren't luxuries. They're the baseline food environment for most of human evolutionary history. Northern latitudes are the exception.
If you live in a cold, dark climate, you have a choice. Eat "seasonally" and limit yourself to whatever grows locally in January, or use the one genuine advantage of modern life: global supply chains that bring ripe, nutrient-dense tropical foods to your door year-round. Imported ripe fruit, raw honey, grass-fed butter, and quality animal protein are closer to what the human body evolved on than whatever grows in your backyard in February. Eating equatorial isn't unnatural. It's using technology to get back to the conditions the body actually expects.
The Blueprint
Animal protein as the foundation. Quality fats for hormonal support. Natural carbohydrates for energy and metabolic function. No ideology. No unnecessary restriction. Just the foods the human body recognizes, uses efficiently, and thrives on.
Per lb Ideal Weight
From Fat
Carbohydrates
Protein is fixed at 1 gram per pound of your ideal body weight, from animal sources for complete amino acid profiles and bioavailability. Fat sits at around 30% of total calories, enough for hormone synthesis and fat-soluble vitamin absorption. Everything else goes to carbs, which is what keeps your thyroid active, cortisol low, glycogen full, and sleep intact.
Meat is not just protein. A steak contains significant fat, heme iron, zinc, B12, creatine, carnitine, phosphorus, selenium, and a full spectrum of B vitamins. When you eat animal protein, you are simultaneously getting the most bioavailable forms of nearly every essential micronutrient. The protein category carries the bulk of your nutrition with it. That's why the rest of the framework can focus purely on energy and hormonal support.
Carnivore gets people further than almost anything else out there. But the bar was never "better than the standard diet." The bar is optimal. And optimal means giving the body everything it needs: animal protein for structure, quality fats for hormones, and natural carbohydrates for energy. Everything carnivore does right, with everything it leaves on the table. The Blueprint.
