Carnivore Diet Results: Before and After Pictures

By Liam McAuliffe Updated on

Carnivore diet before and after pictures are a testament to the transformative power of realigning with our ancestral dietary patterns.

This means eating only fatty meat and animal products, often combined with intermittent fasting.

If you’re coming from a  standard American diet high in carbs and plant-based foods, this nearly all-meat diet sounds unbelievable.

Carnivore eating is loaded with saturated animal fat and high-cholesterol foods. There’s no fiber, fruits, or greens. Yet the before and after pictures demonstrate how cutting carbs and eating fat routinely results in dramatic weight loss. 

It also important to note that weight loss is only the most visible “side effect” of going carnivore. 

Thousands of people credit a carnivore diet as the key to reclaiming metabolic health, fitness, and mental clarity while reversing numerous disease symptoms and kicking medications. So these before and after pictures convey a much deeper and mostly invisible story about health and healing.

What the Carnivore Studies Show

Recent studies from Harvard and Revero, a carnivore diet community lead by Dr. Sean Baker, have reported powerful benefits for thousands of participants. 

Both studies show how a carnivore diet can significantly improve and even resolve numerous diseases, reduce medication use, improve gastrointestinal conditions, boost mental health, clear up skin conditions, and promote weight loss.

Harvard Carnivore Study 

The researchers concluded, “Contrary to common expectations, adults consuming a carnivore diet experienced few adverse effects and instead reported health benefits and high satisfaction.”

The positive health benefits including:

  • 93% improved or resolved obesity and excess weight
  • 93% improved hypertension
  • 98% improved conditions related to diabetes
  • 97% improved gastrointestinal symptoms
  • 96% improved psychiatric symptoms

Revero Survey

Similar to the findings from the Harvard study, the Revero carnivore-based health program shows widespread reports of health improvements, symptom reversals, and medication terminations.

Carnivore Before and After Pics

Let’s be clear about one thing, these carnivore diet before and after pics aren’t about fat shaming. They’re here to celebrate the transformative power of reclaiming your metabolic health. 

In fact, our ability to store fat on our body is probably the most important adaptation in human evolution. It’s a testament to the central place of fat in our diet. Humans are fat-eating, fat-metabolizing machines.

It is also important to note that it is both possible and very common to have significant body fat and be metabolically healthy. At the same time, many skinny people are metabolically unhealthy.  

Obesity is only one of the many symptoms of metabolic disorders caused by a diet high in carbs, vegetable (seed) oils, and added sugar

Focusing on losing weight to “get healthy” is misguided. The real key to metabolic health, as these before and after pictures attest, is changing what we eat. 

Joe Rogan

joe rogan carnivore diet before and after pictures

Podcaster Joe Rogan practiced a version of the lion diet popularized by his guest psychologist Jordan Peterson 

For 30 days, Rogan’s diet consisted of grass-fed beef, elk, eggs, and bacon. He lost his gut and 12 lbs of excess weight, and his before and after pics reveal the change. 

He did have carnivore diet diarrhea for the first 2 weeks–which is not uncommon as your body adapts to an all-meat diet.

Reporting on his experience to Tom Papa, Rogan said, “When you have no carbohydrates, one of the things that’s amazing is that there’s no crashing. My energy levels were amazing.”

Now Rogan is back on a variation of the carnivore diet that calls for just meat and some fruit.

Miki, a bartender and personal trainer shared her carnivore diet before and after pics with Miki, reported: “The benefits I’ve seen since starting the Carnivore Diet would be cleared skin. I’ve always had acne throughout my life to a point that my family members called me Pizza Face. Now that’s not a problem. I would also say that my stomach isn’t pudgy, my body is well balanced, and my energy level is amazing that I don’t need coffee but just drink it because I love the taste. No more anxiety or depression.”


Raymond Nazon


Raymond overcame a list of ailments, all of which are invisible beneath his newly defined abs in these before and after pics. His pre-carnivore issues included:

  • Diabetes
  • Rosacea
  • Back pain
  • Arthritis
  • High blood pressure
  • Irritable bowel disease

Sharing his carnivore diet before and after pictures, Nathan says, “Up until three years ago, I ate the standard American diet. This included no limitation to carbs, no macro tracking, and zero self-control. I was truly struggling with my health at this time. To put this simply—I was dealing with severe neurological problems that no doctor could understand. It was debilitating to the point that I had to put school on pause. 

After having been to the Mayo Clinic and receiving zero answers to all of my problems, I decided to visit The Center for Functional Medicine at Cleveland Clinic. After discovering that mold illness was the cause of all of my neurological problems, my doctor placed me on a ketogenic diet. With time, this diet nearly completely eradicated my mold illness. I transitioned to the carnivore diet in March of 2019 in order to reap further benefits of the ketogenic lifestyle.”

The benefits of this way of eating have been incredible, to say the least. To keep this simple, I will list the benefits of transitioning from traditional keto to the carnivore diet:

  1. Consistent energy throughout day
  2. Much leaner body mass
  3. Perfect digestion (zero bloating)
  4. Better sleep
  5. Huge improvement to weight lifting performance
  6. Clear skin
  7. Mental clarity

I exercise five days per week. I primarily focus on weight lifting. My strength has only increased with this WOE.

Make this diet as simple as it should be! Learn to listen to your body! If you are coming from a non-ketogenic diet, just be prepared for the first week or so being slightly difficult. The initial adaptation from carbohydrates to fat can be difficult. Know that all of this is worth it, though!

Kelly Hogan

carnivore diet before and after weight loss picture

“Since removing carbs from my diet and eating only animal foods, I am energetic and pain free. Completely freaking PAIN FREE. Is there any better gift??? ❤️ I can walk for miles on the beach without needing a rest, hunt shark’s teeth all day without having chest pains or leg cramps, and I still get to eat like a queen. I don’t go hungry and don’t force myself to eat any meats that I don’t enjoy. I truly can’t imagine a better life!

I need to eat only animal-foods in order to feel my best, but no matter how you need (or want) to eat, I can wish nothing greater for you than to feel happy and to be pain-free. Occasionally seeing an ab muscle or getting better body composition is fun, no doubt. But to just FEEL GOOD is amazing and something that I hope to never take for granted. (Bonus points if we also feel content, loved, motivated, kind, hopeful, creative, or generous. But being pain-free and well-fed is a great place to start. 🙌🏼)

Eat the meat. Save the humans. ❤️

“In May 2017 I just didn’t care anymore and went full carnivore. I had tears in my eyes and started crying of bodily happiness after my first bite. The next day I had tears of joy just on my way to the butcher. The body knows best.”

Hey There, world! I’m new here👋🏼

Here I am, putting it all out there…Being another voice amongst those who are bringing you their stories of success and personal victories. 💪🏻🧠

My name is Mindy and I am probably like you; a lifelong dieter. Someone trying to manage living with autoimmune and metabolic disorders while enjoying all that life has to offer.

Here’s (some) of my story: I am 30 years old and in the best health I’ve been for as long as I can remember. I became overweight and sick as a young teenager after being diagnosed with PCOS, and Metabolic Syndrome “x”…It came out of left field and navigating my teen into young adult years being overweight was no easy feat.

I would spend most of my time dieting and searching for ways to “heal” myself. Name the “diet” and I’ve done it.

in 2017, I became aware of the #keto diet and started it out instantly amazed with the results and the way I would begin to feel. It was like taking a weight off of my psychological health in addition to my body.

I’ve had to learn through the years that this journey I am on is not about a number on the scale or a pant size. This is about optimal health. Through ups and downs, literally and figuratively, this all came together for me full throttle in 2019.

2019 was all about healing mentally AND physically. Lifting the weight of conscious worry and physical weight.

I lost 100lbs between 2019 & 2020. I #healed my #pcos and blood sugars, and vastly improved my #mentalhealth without stressing about cravings OR numbers on the scale. My life has literally changed.

I am human. I am constantly learning, like you, how to stay on track and how to continue to manifest and achieve all-around health. There is no finish line and I am so thankful of this awareness.

More to come on how I am managing life and how I’ve adapted ancestral and #primal #living into my everyday life!

Excited for this space to share and to encourage end help others improve their health and living😍

  • Happy? Yes
  • Confident? for the most part
  • Feel “GOOD” ? Rarely to Never.

Being that weight was hard. I felt really bogged down constantly. Always fatigued and ugh always hungry. I didn’t realize how “weighed down” I was physically therefore emotionally…missing out on a lot because I was so run down. I didn’t know that my lifestyle was so hindering until I made a change. 😍

The girl on the right still has ups and downs, but overcame so much to feel “GOOD”

Carnivore Diet Before and After Pics: The Takeaway

These carnivore before and after pictures are a testament to the power we have to take control of our lives by changing what we eat. 

Though weight loss is not the goal nor the most important benefit of a carnivore diet, it is the most visible marker of the dramatic physiological changes that can take place on a carnivore diet. 

Unlike other diets, going carnivore doesn’t require counting calories. You simply eat the foods your body is designed to thrive on while cutting out the crap that it’s not.
