Carnivore Diet Blood Work
Meal after meal for well over a year. Not one bite from a plant. Not a piece of fruit, not a serving of vegetables, not an occasional treat. Nothing but meat and some eggs. And here are the results of my Carnivore Diet Blood work.

When my test results arrived, they came with a warning from the facility to go see a doctor. And instead of seeing a doctor, I’ve been thinking about how to write this post – how to describe my carnivore diet blood work in the most helpful way.
This post has taken a long time to write. I started writing about lipids, attempting to describe the complex interplay of cholesterol and triglycerides in the metabolic machine, our bodies.
But as I was weaving together the intricate interplay between my lipid panel, metabolic panel, and complete blood workup in an attempt to draw a coherent picture of the complex interactions of blood, hormones and lab values in the context of my carnivore diet and lifestyle, I realized what I really needed to write here.
If I can drive home this one thing, I’ll consider this post a success.
Carnivore Diet Blood Work: The ONE Thing
Because really this post is not about my carnivore diet blood work, nor is it about understanding all the biochemistry and physiology. Rather, it’s about understanding the framework of health in order to have a clue what your picture of health actually shows.
So instead of painting a picture of my carnivore diet lab results, I want to show you the canvas and the frame, so you can be your own artist. And at the end, I will show you some paint strokes – describing my blood work – as a means to help you paint your picture.
By the time you understand the canvas and can see the frame, you’ll understand what blood work is, if and when you should get your blood work done, and what it all means.
Carnivore Diet Blood Work: What You Need to Know
Solving the Puzzle
I want to extend our canvas analogy.
If the canvas is your picture of health, imagine the painting is cut up into innumerable puzzle pieces. If you can gather all the puzzle pieces, fit them together, you can see the picture.

The first challenge in solving the puzzle is gathering as many pieces as you can. Getting blood work done gives you some puzzle pieces. Pieces that you can start to connect.
Puzzle Dynamics
This is no ordinary puzzle, however. It’s very tricky. It’s dynamic.
The puzzle pieces change size and shape continuously. And not only the pieces, but the overall picture changes with it.
And all the pieces influence all the other pieces. Just imagine one tiny puzzle piece changing shape, which then slightly alters all the puzzle pieces, and the overall final picture. If you think it sounds like an impossible puzzle to solve – you’re right.

The only way to extract meaning is to understand it as a dynamic system.
People often make the mistake of viewing blood work as a picture of the whole puzzle. When really, your blood work gives you just a few pieces of the puzzle. And if you just put these pieces together and think these pieces show the whole picture it’s easy to draw false conclusions.
With limited perception what you think you see isn’t always what’s there. A puzzle piece (i.e. a lab value) can be an odd shape (i.e. “high” or “low”) for good reason or bad reason. That irregular shape could be just the perfect fit for that place and time. Or it could be irregularly shaped because there is a problem.
The Frame
The key to putting the pieces together, the key to actually being able to “solve” the puzzle, is to look at all the pieces in context with all the other possible pieces.
The frame that hold the canvas is context.

Context is the key.
Without context we assume your puzzle is the same as my puzzle and all our pieces should be the same.
However, your puzzle is a certain age and gender, it has certain genetics, lives in a certain area, and has a history of certain experiences, certain diets, and habits. No puzzle is the same as yours. The frame of your canvas is unique to you. The puzzle pieces that fit in your frame shouldn’t necessarily be the same shape as my puzzle pieces.
The Indecipherable Puzzle
If you just look at the puzzle pieces from your blood work you have an indecipherable puzzle.
You have this massive frame and just a few puzzle pieces. There is so much empty space in the frame that any attempt to conclude what the picture shows is a guess.
But when you add other pieces – diet, lifestyle, stress, age, gender, occupation, health and history (health, medical, diet, injuries, changes) you can start to see a more full picture.
Now even if you gather all these pieces, you still can’t completely solve the puzzle.
The reason is that the puzzle is dynamic. It’s always changing. Puzzle pieces change shape and size with the time of day, with the season, and unless you live in a bubble these changes are difficult if not impossible to control and account for. [r]
Perhaps one of the biggest secrets to getting a good glimpse of the whole puzzle is to acknowledge the fact that the puzzle is ever-changing so at any one time you can get a snapshot, but a snapshot the next day could, and likely will, look different.
Carnivore Diet Blood Work: When to Get Tested
Gathering Puzzle Pieces
Daily I get a message from someone who has completed 30 days on the carnivore diet, got their blood work done, and is then worried about some number on the report.
They ask me what I think.
And (after responding that I don’t/can’t give medical advice to them) I have to respond with the same “I don’t know.”
Problem #1
The first problem is all they gave me is a few pieces of a gigantic puzzle.
It’s also like handing me 5 pieces of a 5-million-piece puzzle and asking me what’s the picture on the puzzle. And even if all 5 pieces seem to fit together perfectly, I’m still just seeing a miniscule part of the whole picture.
Problem #2
The second problem is getting a test so soon after a major dietary change, is like handing me puzzle pieces that morph in size and shape before my very eyes.
I can’t tell what fits with what. Or if I could, it might fit for a second, before it doesn’t fit again.
It’s not that it’s bad to get tested this earlier, it just doesn’t tell you much. But if you continue for 6 months and get more blood work, and then another year and get more, you can start connecting some dots – start seeing a more clear picture.
When to get Blood Work
For most people, I don’t think it makes sense getting blood work after 30 days or even 90 days after a major dietary change (unless you have the time and money – then go for it).
I think it’s more valuable to first reach a homeostatic position with the diet and lifestyle. If your weight is still fluctuating, hormones are still rebalancing, just wait.
The point of the blood work is to help get meaningful puzzle pieces. And ongoing testing, whether it’s every 6, 12, 18, 24 months can help connect dots over time, again helping to draw a more complete picture.
What tests to get and how often is very individual.
As you’ll see with my results, there are some markers that I will test more frequently and others that I may test less often. My subsequent testing (both the tests and the interval) will be different than yours. But getting blood work on a recurring schedule that you and your doctor determine is a good way to keep a pulse on these parts of the puzzle, and it helps you connect dots over time.
Carnivore Diet Blood Work: Where the Confusion Arises
Obviously, the complex nature of our individual puzzles leads to a lot of confusion. But what complicates matters even further is that everyone looks at these puzzles through different frames.
Context Clues
I spent two decades studying nutritional biochemistry and physiology from the viewpoint of a bodybuilder.
When I studied, read research, and experimented it was through a lens of building muscle and losing fat.

It’s fair to say – I viewed nutrition from a different angle than say an oncologist.
Muscle vs Metastasis
Just this morning I was asked on Twitter if “carbs are needed to maximize muscle gains?”
Bodybuilding Frame
Well, to build muscle there are some very important hormones like insulin and IGF-1, without which no matter how hard you press that bar or curl that dumbbell your muscle size and strength will be severely limited.
Spiking insulin post-workout via fast acting carbohydrate is a strategy many bodybuilders use to signal to the body “time to grow.” Bodybuilders will often combine these carbs with protein. Carbs spike the insulin and the protein goes to work building and repairing. This energy signals mTOR to “turn on” which stimulates cellular growth by activating IGF-1.
All good in the context of building muscle.
Physician Frame
But through the eyes of many healthcare practitioners, insulin, IGF-1, and mTOR are all bad.
A common thread among obese and diabetic patients (and so many chronic diseases) is hyperinsulinemia – chronic high insulin levels. Insulin is bad news.
Through the eyes of an oncologist – insulin, IGF-1, and mTOR –are really bad. They fuel cancer growth.
But through the eyes of a longevity researcher the story may change.
Longevity Researcher
The researcher may conclude that turning these growth factors “on” as much as possible could increase longevity. Greater muscle mass is consistently one of the best predictors of living a long life and lowering all-cause mortality rates. (r, r)
So are these hormones good or bad? Who is right, the bodybuilder and longevity researcher or the physician and oncologist?
No one is wrong, per se. The context is different.
If you see insulin, IGF-1 and mTOR only from one vantage point you may miss the whole picture. A bodybuilder will conclude they are great for maximizing muscle growth. An oncologist will conclude they are great at fueling cancer growth.
The frame you look through matters.
Carnivore Diet Blood Work: Cholesterol Context Clues
I want to look at a couple of examples of understanding labs values and nutrition in context.
Cholesterol
If the average doctor looks at my blood work, they may have a heart attack. And they’d likely think I’m on the verge of having a heart attack with them.
But they would be missing all the context – looking through the wrong frame or only seeing part of the picture.
Cholesterol can be “high” for good reasons and high for bad reasons. I am going to write specifically on cholesterol in the future, but for now, it’s enough to know that many factors influence cholesterol levels.
Cholesterol and Metabolism
For example, if you eat a high fat, low carbohydrate diet, the way the energy is distributed throughout the body is very different than someone who eats a carbohydrate-rich diet. (r)
If a doctor is missing this context, or perhaps doesn’t understand how this process works, they will say things like your cholesterol is high and you need to be on a statin.
Well, they will be right and wrong. Your cholesterol very well may be “high” compared to others on a the Standard American Diet (SAD), but it is high for good reason. The body is functioning exactly as it should. He’d be very wrong in suggesting cholesterol lowering medication.
Measuring What Matters
One of the most challenging obstacles in health science is measuring what matters.
For example, drugs are often developed to reduce the risk of heart attack or stroke with a goal of long term survival. These are hard to measure without long-term clinical outcomes. So instead, pharmaceutical companies use indirect “surrogate” or “proxy” measures.
Proxies help get drugs to market as fast as possible.
Blood Sugar or Death
For example, the drug Avandia is good at controlling blood sugar. Since blood sugar is easy to measure it was used as the proxy for this diabetic medication.
The problem is that 2 out of 3 diabetics suffer heart complications. So, one of the main goals of diabetic treatment is to reduce the risk of heart problems.
But what happened with Avandia is that although it helped control blood sugar, that proxy measurement got confused by what actually matters – death. And in Avandia’s case it increases the risk of heart attack, stroke, and death. (r, r, r, r, r, r, r)
The proxy (blood sugar) didn’t correlate with the outcome (mortality).
This happens all the time.
Cholesterol Proxy
Statins are prescribed to lower cholesterol. Cholesterol is a proxy. There are drugs like Vytorin and Zetia which are great at lowering cholesterol. But they have no evidence of lowering heart disease or stroke. But lots of evidence of adverse side effects. (r)
I bring up proxy measurements because you may have a puzzle piece that looks irregular, like my cholesterol. And if this proxy (puzzle piece) isn’t seen through the correct frame it can cause you to worry. And further, it’s important to recognize that if a puzzle piece is used as a proxy to predict what the whole picture looks like – it could easily be wrong.
It’s like saying “if this one puzzle piece is a certain shape, then we predict your whole completed puzzle looks like this.” But often that puzzle piece isn’t representative of the whole puzzle.
Carnivore Diet Blood Work: What is it?
A helpful way to view your blood is to see it as a delivery system (of oxygen and nutrients) and a disposal system (of wastes products).
Certain organs are stops along this system for processing before delivery or dumping – like the liver, kidneys, spleen, and lungs.
Blood work is a snapshot in time to get an idea how this system is working.
There are thousands of tests you can get. All are puzzle pieces.
I ordered the three common panels – lipid panel, metabolic panel, and a complete blood count – as well as a few less common tests like insulin and hs-CRP.
This is not to say these are necessarily what you should get.
For example, if I had signs of metabolic syndrome, I’d get my fasted blood sugar, a glucose tolerance test, hemoglobin A1c, and fasted insulin to see how they work together for a more complete picture.
Or if I had risk factors associated with cardiovascular disease, I’d get a fractionated lipid panel, which is a more in depth look at the lipids.
Carnivore Diet Blood Work: My Results
Here are my blood test results.
Lipid Panel
The lipid panel measures two types of fats – cholesterol and triglycerides.
And the first thing that jumps out when looking at my blood work is my cholesterol. It’s “high.”

And I am perfectly happy with it.
My HDL is quite high, my triglycerides are quite low. This is the ratio I really care about. I have very low remnant cholesterol. Based on this, my LDL is of absolutely no concern to me. (r, r) If you want to know what numbers are important, here’s my list.
As far as I’m concerned, I’m happy my brain and body are getting all the cholesterol they need. (r, r) And to me it’s further evidence that I’m a fat burner, which isn’t too much of a surprise as I’m eating almost no carbohydrates, I’m quite lean, and train daily.
Metabolic Panel
The metabolic panel gives me a look at the processes in the body that convert or use energy.
Here I get information about minerals which can impact things like water balance, blood acidity, and muscular function (i.e. calcium, chloride, magnesium, phosphorous, potassium, and sodium).
I get information about organ function like the liver and kidneys through values like bilirubin and albumin.
Lots of puzzle pieces here.

And to the casual observer, a couple puzzle pieces look irregular in shape.
BUN and ALT
My blood urea nitrogen (BUN) as well as my alanine aminotransferase (ALT) are high. “My liver and kidneys are failing!” No, I fully expected this.
In the context of a high protein diet and daily training BUN is often elevated due to the high rate of protein metabolism and muscle turnover. (r, r) People fear metabolic acidosis but looking at my metabolic panel there just isn’t any evidence of this whatsoever.
The same goes for ALT. Elevated liver enzymes are very common in people who workout hard on a regular basis. ALT tends to remain elevated for 7+ days post workout. (r, r) And I workout every day.
I could have taken a week or two off…oh who am I kidding, I couldn’t do that.
There are a couple other values that I want to highlight.
Insulin
A fastest insulin test is one of the simplest, most affordable, most accurate tests to evaluate metabolic health. Hyperinsulinemia underlies so many of our modern chronic diseases – everything from heart disease to cancer to dementia. The biggest killers.
Blood glucose and HbA1c are valuable, but fasting insulin can detect problems before insulin resistance (pre-diabetes/diabetes) starts to set in.
My insulin was 2.3 uIU/mL.

This is very low. For perspective, anything below 2.0 is undetectable. This is the opposite of insulin resistance. I’m very insulin sensitive.
There isn’t agreement on what is ideal, but a study out of Arizona found that women with a fasting insulin around 8.0 had twice the risk of prediabetes as those with 5.0. (r) And research from the University of Washington showed “the average insulin level in the US is 8.8 mIU/ml for men and 8.4 for women.” (r) And based on our metabolic health, this is way too high. From the research I’ve done, I would say 2-5 is an ideal range.
If you are getting your blood work done, ask you doctor if you can include this test.
HS-CRP
A second test I ordered which is out of the “norm” is a high-sensitivity C-Reactive Protein test. CRP is a protein the liver makes when there is inflammation in the body. This test is used to evaluate inflammation as well as risk for heart disease. And you want it to be below 1.0.
CRP is traditionally measured down to concentrations of 3-5 mg/L, but with hs-CRP we can now detect even low-grade inflammation down to 0.2 mg/L.
My CRP was so low it was beyond detection (less than 0.2 mg/L).

This is a good sign that I don’t have any kind of chronic systemic inflammatory problem and quite low risk for cardiovascular disease. (r)
If meat was inflammatory or if it was a cause of a chronic inflammatory reaction, like from an autoimmune response, it would be detected via CRP.
It’s important to note that CRP can be elevated by many inflammatory diseases, cancers, and infections. But if it’s elevated, it’s an important puzzle piece to investigate.
Complete Blood Count (CBC)
The CBC gives me a look into the health of my blood cells – red, white, and platelets. I can see the quantity, size, and volume as a broad screening tool to detect possible infections, allergies, or diseases like anemia or leukemia.
My blood is pretty boring, all values sitting within normal range.

Carnivore Diet Blood Work: Values of Note
I want to point out a couple values of special note in relation to the carnivore diet.
- Homocysteine – On a carnivore diet people fear insufficient folate. Yet if I were deficient, my homocysteine would likely be high. But it’s right in the normal range. People on plant-based diets tend to have high homocysteine levels – associated with higher likelihood of cardiovascular disease and death. (r)
- Uric acid – Many people have concerns about the high purine levels in meat and gout. Not an issue.
- Calcium – I eat little to no dairy, and my calcium is in the high normal range.
- Testosterone – When I announced I got my blood work, this was the one number most men asked about (it was in the high/normal range):
- 915 ng/dL total testosterone
- 101.8 pg/mL free testosterone
- Estrogens – Low/normal
- Thyroid – TSH is normal
- Blood Sugar –
- Glucose: 89*
- Insulin: 2.3
- Hb A1c: 4.9
*Although a blood glucose of 89 falls within the “normal” range, and I’m clearly not diabetic based on the other values, my blood glucose is higher than most would anticipate given this data. But this isn’t uncommon among low carb athletes. There is a theory called “Adaptive Glucose Sparing” in which the body preferentially uses fat for energy and resists the use of glucose, saving it for certain tissues like the brain and red blood cells.
Carnivore Diet Blood Work: Irregular Puzzle Pieces
When I got my blood work results I had two irregular puzzle pieces that didn’t make immediate sense to me. This gives me a good opportunity to explain my thinking process around irregular puzzle pieces.

DHEA Sulfate
The first puzzle piece that that didn’t seem to fit was my DHEA. It was a bit low. Not super low, but low, nonetheless.
This value was particularly curious because DHEA is a precursor of testosterone and my testosterone was quite high.

DHEA is produced by the adrenals and it does tend to be high in young male athletes. But like many hormones, it has numerous roles. It also tends to be high in people with insulin resistance and chronic high stress. It’s obviously influenced by a myriad of factors.
Testing DHEA
Doctors generally order DHEA test because they’re worried it’s too high (not because they think it’s low).
DHEA can be high for numerous reasons like stress. In stressful situations the adrenals release cortisol and DHEA. For example, it is often elevated in people suffering from PTSD. (r)
Generally, a tests is not ordered for suspicion of low DHEA unless Adrenal Insufficiency (AI) is suspected. There has been a recent trend supporting testing for “adrenal fatigue” though there is no evidence that “adrenal fatigue” is actually a real thing. (r) To me it makes sense that there are milder forms of adrenal insufficiency that could explain many of the symptoms we face as a result of our high stress modern lives, but medical literature doesn’t support it.
Anyways, searching for low levels of androgens in healthy people without specific symptoms is not recommended, and treating them with androgenic hormones just isn’t the standard of care.
DHEA Insufficiency
Symptoms of low DHEA include poor body composition (fat storage and little muscle), low libido, fatigue, depression, weakness, difficulty in getting up in the morning, and a weakened immune system.
I simply don’t have any clinical symptoms characterized by DHEA insufficiency.
The clinical expression of hormone function is a very important consideration. How you look, how you feel, how you perform are all parts of the puzzle.
So why is my DHEA low?
I have a hunch that it is for a similar reason that my insulin is so low.
In the case of insulin, because my receptors are so sensitive, I don’t need much of it in order for it to optimally perform its functions. In contrast, someone that has insulin resistance needs a whole lot of insulin in order to maintain homeostatic blood glucose.
I’m guessing I have “hypersensitivity” to DHEA.
DHEA Hypersensitivity
Usually this is understood in the context of women who have normal DHEA lab values, but experience symptoms associated with high levels of DHEA – weight gain, hair loss, low energy, acne, irritability, infertility, deepening of voice, recent stress, PCOS.
It’s an imbalance between the amount of DHEA and the receptor sensitivity.
In a balanced scenario “low” DHEA levels would correspond to “high” receptor sensitivity.
And this is my best guess as to why my DHEA is “low.” Just like my insulin is “low.”
Hormone Receptor Sensitivity
I do think with a proper diet, exercise, sleep and general health we see efficient use of hormones (not over-production) with very sensitive receptors.
Insulin is a good example, my fasting insulin is, by some accounts, lower than the lower limit. Extreme insulin sensitivity. I just don’t need much insulin to keep healthy blood sugar and promote healthy growth.
Other hormone receptors like thyroid and leptin can behave much the same way – whereby your organs don’t have to continuously pump out loads of hormones for function. They are efficient.
I think we should be cautious of the reactionary doctor who has an asymptomatic patient with low T3 and wants to put them on Synthroid. Hopefully most doctors try and see through the correct frame to make sense of the puzzle pieces.
Ferritin
The second irregular puzzle piece was my ferritin. It was quite high.
Ferritin is a measure of iron storage.
The easy explanation would go something like this: I’ve been eating a lot of iron so – duh – my iron stores are high. But that would be missing a key element.
Iron Absorption
The liver produces a hormone called hepcidin which monitors iron levels and tells intestinal cells how much to absorb.
On average we lose 1 -2 mg of iron every day – so not surprisingly – this is how much we usually absorb per day.
There are really two main causes of high ferritin levels:
- Absorbing more than normal (hereditary hemochromatosis).
- A reactionary response to inflammation such as: metabolic syndrome (obesity, diabetes), liver disease, daily alcohol, infections, cancers like Hodgkin’s lymphoma and leukemia, rheumatoid arthritis and systemic lupus erythematosus). (r, r, r)
The second one, a reactionary inflammatory response, explains high ferritin in over 90% of cases.
The problem is, the most typical explanations for high ferritin don’t seem to apply to me. I don’t have metabolic syndrome (see Metabolic Panel), I’m not chronically inflamed (see HS-CRP), I don’t drink, I don’t have any infections (see CBC), and I don’t seem to have any cancers or autoimmune diseases.
So perhaps I have hereditary hemochromatosis (HH)…
Hereditary Hemochromatosis (HH)
Hereditary hemochromatosis is a genetic change affecting the synthesis and/or activity of hepcidin. The result is an increase in intestinal absorption of iron and potential iron overload.
The incidence is about 1 in 200 so while unlikely, I definitely can’t just rule it out. (r)
Unfortunately, I don’t have prior blood work with ferritin levels. So I don’t know my personal history. But it doesn’t run in my family. The opposite does – anemia – which is an iron deficiency. In fact, it’s the most common mineral deficiency in the world.
But while my ferritin was high, it really wasn’t in the HH high range (>1000).
Vitamin C can increase iron absorption, but on a meat-only diet, and without supplementing Vitamin C, this isn’t a likely suspect. If I don’t have HH and I don’t have reactionary inflammation, it turns out we really don’t know the cause of mild elevations in ferritin. (r)
This leaves me in an interesting situation. I have an irregular puzzle piece with no immediate explanation.
What to do – How I think about “irregular” puzzle pieces
So here’s what I’ll do and how I think about this.
- I will likely get another iron panel – this time including TIBC (total iron binding capacity). This way I can re-check ferritin as well as see if TIBC >45% (which is an indication of HH).
- If TIBC is greater than 45% then I’d get a genetic test to rule out hereditary hemochromatosis.
- If it is less than 45% and the ferritin is still around where it is, I’ll likely monitor over time.
As the current research recommends, observation below 1000 ng/mL is standard procedure in this case. But if ferritin elevates towards or above 1,000 ng/mL, I will likely get further testing. (r)
I tell you this to show you my train of thought when it comes to blood work.
- What it is – A process of understanding / putting puzzle pieces together.
- What it’s not – A reactionary response to an elevated value and immediate medication/treatment/jumping to conclusions.
At the time of this writing, I haven’t gotten this test yet, but when I do, I’ll update this at the bottom of the post.
Further possibilities…
Although current science doesn’t have definitive answers as to why ferritin is elevated in the absence of an inflammatory response or a genetic condition – there are 2 scenarios I like to always keep in mind.
2 Scenarios
Scenario #1: Perhaps the test was inaccurate.
I have a degree in Chemistry and did four years of quantitative analysis research. Using graphite furnace atomic absorption spectroscopy, I measured lead contamination in fish. I can tell you, no matter how much care is taken, and how good the instrumentation is, no test is immune from error.
If something is outside the normal or expected, and you just can’t explain it – sometimes error can explain it.
Scenario #2: These higher iron storages are good and necessary for something that I just don’t know or understand.
And I think this may be the most likely scenario.
While I do everything I can to understand, to ask why, to get to the bottom of “irregular” puzzle pieces, I know my body is smarter than me.
Many people with my ferritin levels would rush to get a phlebotomy. But what if my ferritin is “high” for good reason? What if my body knows something I don’t? The last thing I want to do is try and manipulate it myself.
I believe this is what is so often done with cholesterol. We think we are smarter than the body and thus manipulate cholesterol with drugs – just to get a number that we think is good. When really that cholesterol is “high” for a reason. That reason may be perfectly appropriate and healthy or it may be that something is wrong. But masking the underlying reason and just manipulating numbers with drugs, I think is a bad strategy.
Understanding vs. Justifying
There is a big difference between understanding the puzzle pieces in the big picture frame and trying to justify puzzle pieces that don’t look good.
For example, I can understand why my cholesterol, BUN, and ALT are high. And not only understand but expected this in the context of my life. It makes sense in how it fits with the other pieces of the puzzle.
But this is not to say that if I see puzzle pieces outside of normal shapes and sizes to justify them with theories.
It justifies just the opposite, to dig in, further evaluate, find some more pieces to see if it fits or if there might be a problem.
This is exactly what I did and am doing with the ferritin and DHEA numbers. I’m digging into to possible reasons. I will monitor and test over time. I’ll keep an eye out for issues and explanations. And seek out more informed experts and opinions if called for.
Carnivore Diet Blood Work: Conclusion
As I hope I made clear – lab values are just a few pieces of a very complex puzzle that needs to be put together in the right frame.
Since you are reading this you are probably like me, you self-educate, you’ll try putting your puzzle pieces together, and try making sense of your frame.
But please, please, please don’t take this to mean doing it alone.
Work with your doctor. This, as I hope you know, is not medical advice, rather this is advice to get medical advice, to work with your doctor and specialists and whoever you need to so that you can make the most informed decisions regarding your health.
If you’d like to learn more about what to watch out for on a meat-based / carnivore diet, I’d highly recommend watching the Meat Health Masterclass:

Hi Kevin.
I have ran my blood work (keto/carnivore for 1 year), and like, my Ferritin is high despite an otherwise normal iron panel.
Did you get a chance to run the TIBC test? Unfortunately, my lab does not do it.
Yes, I actually have a polymorphism in the HFE gene that can lead to increased iron absorption/higher ferritin levels.
Thanks for your feedback, Kevin.
Any thoughts on how you are going to manage that, assuming the high Ferritin numbers “could be” a concern, in the face of all other risk markers looking good?
Hi, i am currently in a larger calorie deficit and my cholesterol is quite imbalanced for a 3 year carnivore. LDL increased to over 300 and HDL decreased below 50. is it possible that this is because of the calorie deficit (current macros for fat loss – 50% fat, 50% protein in a large deficit)?
Any reason why you are in a deficit? Trying to trigger more weight loss, or?
HI Kevin, thank you for the interesting and carnivores-reassuring article! You’ve mentioned your raised ALT there. I’ve been on carnivore diet (Paleo-Ketogenic version, PKD: about 300g of red meat and organs and 100g fat per day) for the last 4.5 months after a severe flare of the newly diagnosed Crohn’s. Prior to developing severe form of Crohn’s, for 2.5 years I was on just plant diet, all home cooked only, mainly fresh salads, freshly made juices, with no gluten sugar, grains and dairy. After being treated in hospital I’m now on no medication for 4.5 months. My recent blood test though showed ALT 3.5 times above the norm (112iu/L (Norm 0.0-33.0) and AST was slightly above the norm despite being a tea-total all my life, borderline underweight in the last year (52kg 168cm height), hardly any exercises after the flare due to fatigue and muscle pain when I walk. My GP has mentioned fatty liver possibility and will do an USS of the liver if ALT remains as high in 4 weeks. My CRP on no medication is 1mg/L, so no severe inflammation is going on. I add fat (tallow and lard) to my meats as per PKD ratio and I am surprised because fat is supposed to help treating fatty liver, not damaging it. Any thoughts to try to solve this puzzle?
Hi Kevin,
I am considering not taking ATORVASTATIN any more. Seems I want my cholesterol to be higher. I want my HDL to be higher and Triglicerides lower. My health is good, my heart is strong. Seems like this medicine is interferring with my goals.
My chol total is 180
My Trigliceride is 237
My HDL is 34
My LDL is 108
Chol/HDL ratio is 5.3%
I am staring Carnivore again after going off it 6 months ago. I regret stopping.
What do you think?
Mike
Hi Mike, I’d recommend checking out this article: https://www.kevinstock.io/health/cholesterol-and-the-carnivore-diet/
Hi Kevin, appreciate your work greatly. I am 71 & been carnivore for 6 months now after keto for 6 months. I started keto because my HbA1c was 11.4! & weight was 103Kg. It dropped to 6.3 but now is rising again & is now 6.6. Now, weight is 77.5Kg, CRP is .5, Insulin 4, HDL nice & high etc. Just the HbA1c & ALT too high. My doctor thinks I’m cheating but I’m pretty strict. Any ideas?
Hi Bob – sounds like you’ve righted the ship!
If you and your doctor are really worried about 0.3 increase in HbA1c, then I would simply up the fat and decrease the protein a bit (i.e. focus on fattier meats).
Much more on this here: https://www.kevinstock.io/health/high-protein-diets/
Also, sometimes slight elevations on zero carb happen as means of glucose sparing and very well could be perfectly physiologically normal and healthy (so worth mentioning).

Hello,
I need some help…
I’ve tried carnivore 3 times. It’s fantastic for effortless weight loss and hunger control. But I’m having a huge issue. GOUT!!
I’m not talking a little pain. I’m talking 2 weeks on crutches, unable to shower or use the toilet without assistance, so sensitive that if the sheet touches my ankle it hurts, pain. The first 2 times i tried carnivore, it happened within a month, and, of course, i reluctantly backed off the meat and tried to do a mainly eggs and avocado (both low purine foods) keto diet.
Eventually, my awful food addiction and lack of self control got the better of me and I went back to eating like an idiot.
This year, I wanted to stick with it, hardcore.
I read all these articles and saw all these videos with carnivores, claiming that fructose is the problem. The few videos i could find on people who experienced gout on carnivore, the general idea i was given, was that an initial flare-up during adaptation is possible, but after the first 2 months, you should be in the clear.
Well, I’ve been through the adaptation. Been strict (er….98% I still drink black coffee) carnivore since February. Nothing but red meat, eggs, black coffee, salt and water since March 15th (before that, I was allowing myself cheese). Not one cheat meal, and here i am on crutches, trying reduce swelling and manage pain with rest, ice, elevation, colchicine and indomethacin.
I don’t want to give up carnivore. It makes weight loss so effortless, but absolutely nothing is worth this level of physical pain. Not to mention not being able to do anything for myself.
Any information you think might help would be appreciated.
Hi George, I’m writing an article on this (and protein) at this moment, but in the meantime, have you seen this: https://www.instagram.com/p/B8b7kAWgLQk/
Try giving up Eggs.. you could be intolerant to them
Hello Maztergee
Your advice inspired me to take a food intolerance test
I did it, eggs the green light. So did cheese, red meat, pretty much everything you can enjoy on carnivore is good with me. But, apparently, my gout disagrees. Didn’t narrow it down, but it was worth a shot.
Thanks for the idea. 🙂
Hey George, don’t know if you’ll see this but if you do I’d be really curious about where you’re at now? I started ZC in July and had a brutal two months of back to back gout. I still have the occasional flare but (thankfully) comparatively minor.
The turning point for me was giving blood. I saw a talk by Amber O’Hearn which had a chance comment at the end that in addition to fructose, for some people high iron is a trigger. Did some research and found lots of people with gout talking about giving blood as a way of minimising attacks. Giving blood is the only really practical way of reducing iron, so I did that. And the back to back flares stopped immediately. I obviously can’t prove causation, but it was a pretty dramatic change.
The other thing I’ve noticed is that every time since I’ve had a minor flare, I have ketones in my urine (and normally have none despite being in nutritional ketosis according to a blood test). So my theory is that I’m doing something which is causing me to produce more ketones than I can use, and since ketones take precidence over uric acid for excretion by the kidneys, I get a uric acid build up.
Hi Adam,
Thank you for your response, fellow gout sufferer. I have since gone off the carnivore diet, and am just focusing on gout. Currently, I eat one meal a day, and almost every day, I have at least 4 organic, pasture raised eggs (because eggs are the only low purine, nutrient dense animal based food I know of).
I really do want to go back on carnivore, because it makes weight loss so effortless, and I definitely gained back some weight in July, and again in October. I think i might be able to do it without a flare-up now, as my rheumatologist put me on 300 mg a day of allopurinol, and gave me some indomethacin and prednisone (so that i have options) in case of another flare-up.
My main concern is my own lack of self-control. I know that if i eat one meal a day, regardless of what i eat, if i follow the one plate rule (one average sized dinner plate, piled no more than 3 inches high, nothing falling off the side of the plate), i will lose weight, slowly, steadily and surely. And my gout only flares up, if i have too much alcohol without enough water (and I really only drink once a month anyway), or if i have liver or shellfish. I can have a ribeye and a potato for dinner, wake up a little lighter the next day, no gout pain.
But if i go on keto or carnivore, one beer, or one cheat meal, is all it takes for me to have a crippling flare-up. I know the obvious solution would seem to be….don’t cheat, but i get flare-ups when i stick to the diet strictly…..although, again, with the allopurinol, this may not happen….. and to be honest, as a craft beer geek, I do not see myself going the rest of my life without the occasional (1-3 a month) IPA or imperial stout.
I think i may try once more, and keep my fingers crossed that medications get me through any complications that may arise.
Speaking of which, are you on any meds? If you aren’t and you get another flare-up, I would definitely recommend seeing if your doc can get you on allopurinol. It’s been a game changer for me.
Anyway, that is interesting about giving blood. I may have to give that a shot, when/if I give carnivore another go. Do they try to force cookies/juice on you? If so, how did you get out without partaking? Did you feel ok after?
Also, what you said about ketones competing with uric acid to be excreted makes sense. I had read somewhere that extended fasting could be really bad for a gout sufferer. That would explain why. Nothing puts you in deeper ketosis than a fast. I wonder if high fat or protein is the better way to go on carnivore for gout sufferers. I was definitely doing high fat last time (ribeyes, fatty roasts and eggs). Maybe higher protein, less fat, once a month blood donation is the way to go.
If you have any additional info, other ideas or updates at any point, please do respond to this thread. Maybe it will help others in our situation. I hope you never suffer another flare-up again. F*** gout!
Thanks for your input. Take care.
George
Hey George,
Sorry I missed your reply. In the last year I’ve I’ve only had one gout flare (and only one migraine!) and that was from (a fairly minor) deviation over Christmas. I’ve been much more careful since then!
I haven’t given blood since though I’ve been meaning to. Cookies and juice were strictly optional so no problems avoiding them. I don’t drink at all anymore (well maybe the occasional taste of something). I do miss going to the pub with friends, but as they say “nothing tastes as good as being healthy feels”. So it gets easier month by month.
Hope you’re doing well.
Adam.
Regarding cholesterol (and anything else citing studies), it’s important to refer not to just one study but the entire body of studies. As you say, context is key. And as I’m sure you also know, most studies are actually flawed and many more don’t even get published and peer reviewed. By considering the body of studies, one becomes aware of what other experts have to say about that study. It’s continuous peer review involving not just yourself but also with other experts post-study.
I have a family history of heart disease, so I’ve been particularly interested in cholesterol. There’s a great discussion, both in the article and in the comments, here: https://sciencebasedmedicine.org/the-cholesterol-controversy
I’d be interested in your thoughts, particularly in the common errors made by “cholesterol skeptics” as identified by the author and commenters.
Yes, have you seen this: https://www.kevinstock.io/health/cholesterol-and-the-carnivore-diet/
Hello Sarah, I had the same question as you about elevated glucose levels, and lowish ketones. Did you get a answer? Thanks Tom
I have the MTHFR mutation – C677T and A1298C (compound heterozygous). I read a lot about red meat elevating homocysteine levels. Please assist. I want to go carnivore, but don’t know if I should take the chance.
Hi Michelle, I understand the concern, I’d recommend checking out this article from my friend: https://carnivoreaurelius.com/mthfr/
Almost 😉 let me rephrase the question? How could insuline levels be high on a zero carb carnivore diet?
