Unpacking Bart’s Carnivore Diet Transformation – Ketogenic Endurance


Updated October 2023


Hold onto your steak knives, folks! We’re about to delve into a carnivore diet success story that’s nothing short of miraculous. Remember Bart? That 37-year-old certified personal trainer and paleo nutritionist from the UK who turned his life around with the carnivore diet? His story is a jaw-dropping testament to the transformative power of an all-meat diet. From vanquishing chronic health issues to experiencing a newfound zest for life, Bart’s journey is a must-read for anyone contemplating the carnivore lifestyle. So, why is this story so compelling? It’s not just about the diet; it’s about reclaiming one’s life. Let’s sink our teeth into it, shall we?

Bart’s Carnivore Chronicles

Bart Jankowski was a man plagued by a litany of health issues. From irritable bowel syndrome (IBS) that lasted over two decades to debilitating joint pain, brain fog, and even bleeding gums—Bart was falling apart. His wake-up call came in late 2017 when he found blood in his stool. Terrified it might be bowel cancer, he underwent a series of tests that thankfully came back clear. But the scare was enough to propel him into action.

Initially, Bart tried a strict keto diet, but the results were underwhelming. His symptoms persisted, and his gym performance plummeted. Then came the game-changer: the carnivore diet. After watching a podcast featuring Shawn Baker, Bart decided to commit to the carnivore lifestyle for the entirety of 2019. And boy, did it pay off!

The Mental Health Makeover

One of the most astonishing benefits Bart experienced was a complete turnaround in his mental health. Within just two weeks of starting the carnivore diet, his depression and anxiety lifted like a fog. But why? The carnivore diet is rich in essential nutrients like Omega-3 fatty acids, which are known to improve brain function and mood. Plus, the absence of sugar and carbs helps stabilize blood sugar levels, reducing mood swings and irritability. So, not only did Bart get his groove back, but he also woke up early for the first time in his life—without needing a double espresso!

The Physical Transformation

But wait, there’s more! Bart’s physical health also underwent a radical transformation. His IBS symptoms vanished within three days, and his bleeding gums stopped after just a week. What’s the secret sauce? The carnivore diet is inherently anti-inflammatory, eliminating foods that irritate the gut and cause inflammation. This led to a dramatic improvement in Bart’s digestive health, joint pain, and even his sleep quality. And let’s not forget the energy boost—Bart now runs 30-50 km per month and lifts weights four times a week, all without needing coffee as a crutch!


Bart’s life has been revolutionized, to say the least. He’s not just surviving; he’s thriving. His story is a beacon of hope for those struggling with similar health issues. The carnivore diet, with its focus on nutrient-dense, anti-inflammatory foods, could very well be the key to unlocking a healthier, happier you. So, what are you waiting for? Take a leaf out of Bart’s book (or should I say, a page out of his meat journal?) and give the carnivore diet a try. Your future self will thank you!


Before you rush to the butcher, a quick heads-up: this review is based on an older post, and we can’t confirm if Bart is still reaping the benefits of the carnivore diet. Also, I’m not a medical professional, so always consult your doctor before making drastic dietary changes.


1) Introduce Yourself.

My name is Bart Jankowski 37-year-old from the UK.

I am a certified personal trainer and paleo nutritionist, currently working to become a health coach.

My journey with nutrition started in 2009 when I watched video from Sean Croxton titled “is god stupid?” which completely changed my views on food.

What started me into digging deeper into nutrition was my health situation which year by year was getting worse; my weight was getting harder and harder to shift. My body didn’t recover as well as it used to and it felt like my body is falling apart.

List of health problems I suffered with;

IBS – 20+ years, constant diarrhea and bloated every day (now gone)

Psoriasis (now gone)

Joints and back pain (now gone)

Muscle weakness (now gone)

Brain fog, lack of drive and motivation(now gone)

Memory issues, ADHD, (now gone)

Bleeding gums and teeth aching  (now gone)

Sugar and coffee addiction (now gone)

Cravings off the scale (now gone)

Problem with sleep and waking up (now gone)

Anxiety and depression (now gone)

Yeast overgrowth (now gone)

Lack of energy, two double espressos first thing in the morning. (now gone)

Anger issues (now gone)

Late 2017 after going to the toilet one morning I discovered a lot of blood in my stool which continued for a few days. As you can imagine my first thought was “bowel cancer”.  I started researching, and all the symptoms I had were pointing to that diagnosis.

My GP sent me straight to the hospital to do all sorts of tests; colonoscopy was the next step for me. In the time leading to that procedure, I went deep into reading books on the microbiome, gut health colon cancer you name it.

I decided to cut a few types of food from my diet dairy, grains, legumes, and beans to start with I followed advice from “Microbiome solution” book and started heavy dose of probiotics and to be honest, my symptoms improved a bit.

On the day of the procedure, I was about to cancel it as I told my doctor that “I think I know what happened and I am much better now” to which he replied “your diet has nothing to do with your gut health” I decided to go with the procedure which showed all clear.

I decided after that that I’m going to figure it out and get myself better.

2) How did you eat before Carnivore?

Mid 2018  I decided to go Strict Keto after reading “Keto reset diet” by Mark Sisson. I did full 14 weeks recording all food etc. I have lost a bit of weight around 6lb but my bloating and all other symptoms I listed previously were still there, I hit the wall, and my energy levels in the gym suffered drastically.

3) Why did you try Carnivore to begin with?

I decided to try this diet after watching Joe Rogan with Shawn  Baker podcast in November 2018 I only did it for a few weeks but then I fell off due to Christmas. So 31st of December was the day when I decided I will go full 2019 carnivore.

4) How do you personally approach the Carnivore Diet?

For the first month I started eating Ribeyes, and fattest meat I could get, around 3lb per day.

5) What benefits have you seen since starting the Carnivore Diet?

Within three days my IBS, bloating digestion problems were gone, after seven days bleeding gums stopped, two weeks into it my depression and anxiety lifted and my sleep improved massively, for the first time in life I wake up early 🙂 and the list goes on, I feel better now than in my 20’s

6) What negatives have you found with the Carnivore Diet?

So far I have not found anything wrong about it, to be honest.

7) Do you exercise on the Carnivore Diet, if so how do you find it and what do you do.

Yes, I do I lift weights four times per week, box and run 30-50km per month. The first month was hard when it comes to training but now energy is crazy, and for the first time in 20 years I don’t need coffee before the gym just to get that motivation to train.

8) What piece of advice would you give someone interested in trying this diet, but hasn’t taken the leap yet?

I would say do it for 30 days; you have nothing to lose (apart from fat lol)

9) Do you think Carnivore will ever be accepted as a mainstream diet?

I do hope so, but that is hard to predict, with this constant push towards a plant-based diet and registered interest from biggest companies in the world, it’s going to be a hard battle to relate this message across. I reckon keto diet will be a bridge for carnivore as certain countries such as the UK accepted this diet as a treatment for metabolic dysfunctions so that carnivore could be a natural progression.

10) Anything you would like to add, and where can people follow your journey.

My message is, don’t rely on government agencies or doctors to teach you how to eat, do your research you have all the info you need in your pocket. The only way for us to regain our health is to get back the roots. Look at the food you buy, if that food wasn’t here thousands of years ago don’t eat it, because it looks nice and it has some stamp of approval on it don’t buy it, it is all marketing BS. Don’t be scared of red meat and fat for millions of year those two were the staple of our diet and got us to this point in evolution as a species.

So far I have lost 21lb of fat and still loosing

My waist dropped by 5 inches body fat % by around 8%
