We’ve all heard the contemporary diet “rules” about getting in your daily dose of fruits, veggies, and grains. But there’s a new diet on the rise – one that turns the old nutritional paradigm upside down. One that says goodbye to any and all carbohydrates, and advises that you consume meat – and only meat. Que, The Carnivore Diet.

A carnivore diet seems to fly in the face of all of the conventional nutritional advice. But as it turns out, this meaty diet is something we should all be sinking our teeth into. Why? Well, the carnivore diet, a radical diet to some, might just be the secret to optimizing every single facet of your health and well-being.

Let’s take a look at exactly what happens to your body when you take the plunge into a carnivore diet and how it might just be the secret to better health.

What Is the Carnivore Diet?

The carnivore diet is rather self-explanatory. A carnivore diet is a diet consisting of 100% animal foods. No fruits or vegetables. No bread or grains. No nuts or seeds. Strictly foods sourced from animals. Some even say, only animal flesh, but most admit there’s some flexibility for dairy, eggs, and the like.

This way of eating stems from the idea that our ancestors primarily lived on a diet rich in meat and fish.  Don’t believe me? Try foraging for kale and blueberries in the middle of a Norweigan winter or take a look below at the calorific return rate of different food types per hour spent trying to obtain those foods (notice how the top 7 are all from animal sources).

Truth is that before the modern agricultural revolution that began 10,000 years ago with vast developments taking place in the past hundred or so years, the scarcity of food was real. Given the limited access to plant based foods for much of the year over vast parts of the globe, nutritional power of animal foods like those below, liver, red meat, other organs, it’s no wonder the human evolutionary that craved energy for the most supreme brain on earth path led them to Carnivory.

Calorific Return Rate of Different Foods Per Hour Spent Trying to Obtain Food Source

As you can quickly gather based on this chart, you see how there would be an evolutionary advantage of carnivory due to the fact that you get much more calories per hour spent looking for food when you eat meat.

“Evolutionary advantage,” you say! But what about all the herbivore animals that roam the plains in millions? The crazy truth is that these are all ruminants or foregut digesters. What does that mean? Well, all animals in these classifications have bacteria in their digestive system that converts carbohydrates to fat before it’s even absorbed. So really, cow’s and gorillas are themselves following a keto or near carnivorous diet.

Still, think I’m just blowing wind about wild theories and delusions of grandeur? Hang tight because the remarkable health benefits of a carnivore diet are backed by countless scientific studies and testimonials of those who dared to turn their backs to the supermarketers backing the modern American supermarket.

Let’s take a look at some of the most impressive health benefits that the carnivore diet brings to the table.

What Are the Health Benefits of the Carnivore Diet?

The carnivore diet has been linked to a plethora of impressive health benefits. Let’s check it out!

The Carnivore Diet Can Increase Insulin Sensitivity

Insulin is the hormone responsible for moving glucose out of your bloodstream and into your cells to be used for energy or stored as fat. If you consistently consume carbohydrates and sugar that cause large spikes in your blood sugar, your cells can become less sensitive to insulin – making them insulin resistant. 

This decrease in insulin sensitivity can create a domino effect – increasing inflammation, disrupting additional hormones, and setting the stage for a number of chronic conditions. But cutting out carbs and following the carnivore diet can reset your ability to respond to insulin and reverse any insulin resistance.

The Carnivore Diet Can Help You Lose Weight

The carnivore diet can be a powerful and safe way to shed any extra pounds. The carnivore diet is particularly powerful when it comes to weight loss for a few reasons.

  • Increased satiation: Calories that come from protein and fat take longer for your body to break down – helping you feel fuller for longer. Calories that come from animal sources simply give you more bang for your buck since they are more filling and efficient.
  • Less hormonal fluctuations: Constant spikes and subsequent crashes in your blood sugar and insulin levels can cause a cascade of other imbalances with other hormones associated with hunger, fat storage, and weight loss such as:
    • Leptin
    • Ghrelin
    • HGH. 

Eliminating drastic fluctuations promotes balanced and healthy hormone levels.

  • Increased utilization of stored fat: Even if you don’t stay in a constant state of ketosis, you’re still priming your body to use ketones for energy – improving your body’s ability to utilize stored fat.

This trifecta makes the carnivore diet a triple threat when it comes to weight loss.

The Carnivore Diet Can Decrease Inflammation

The carnivore diet can significantly reduce markers of systemic inflammation (like C-reactive protein and IL-6). This is likely due to a few factors such as:

  • The removal of potentially irritating plant-based foods that you may be sensitive to will immediately decrease inflammation levels.
  • Elevated insulin levels promote inflammation. So minimizing blood sugar and insulin spikes have an anti-inflammatory effect.
  • Omega-3 fatty acids have powerful anti-inflammatory properties.  
  • The carnivore diet supports a healthy gut, which plays a crucial role in mitigating inflammation.

The carnivore diet’s ability to decrease inflammation is one of the key factors that make this way of eating so powerful.

The Carnivore Diet Can Promote Gut Health

Your gut health hinges on two primary factors:

  1. The integrity of your gut lining: The lining of your gut is designed to be a tight barrier. When the integrity of your gut lining is compromised, molecules can essentially “leak” out into your bloodstream.
  2. Your microbiome: Your gut is home to millions of microorganisms which create a delicate ecosystem that plays a monumental role in our overall health.

The carnivore diet is chock full of compounds like glutamine, collagen, and omega-3 fatty acids that help repair and strengthen the integrity of your gut lining. And removing things like extra fiber, gluten, fermentable carbohydrates, and plant toxins prevents irritation and the overgrowth of harmful bacteria in your digestive tract.

The Carnivore Diet Can Enhance Testosterone and Libido

The modern American diet and lifestyle is the perfect prescription to put a serious damper on your testosterone and libido levels. Too much sugar and refined oils, paired with not enough activity and a little extra weight create a vicious cycle that depletes testosterone and can leave your strength, energy, and libido in the tank.

But the carnivore diet is loaded with a plethora of nutrients like cholesterol, protein, and Vitamin D that are essential to the production and synthesis of healthy testosterone levels. Plus, it’s nearly impossible to hang on to loads of excess body fat on the carnivore diet – further promoting a healthy uptick in testosterone and libido.

The Carnivore Diet Can Boost Your Brain Power

Inflammation is like kryptonite to your brain. It can cause brain fog, dull your mental clarity, contribute to depression and anxiety, and worsen mental disorders. The carnivore diet not only cuts out inflammation boosting foods like sugar, refined oils, and simple carbohydrates – it also actively decreases inflammation. 

Plus, the carnivore diet ensures you’re getting plenty of brain-boosting nutrients like:

  • Zinc
  • Vitamin B6
  • Vitamin B12
  • Iron
  • DHA

Many dieters who make the switch to a carnivorous diet report increased mental clarity and better ability to focus almost right away.

The Carnivore Diet Can Combat Chronic Disease 

Chronic low-level inflammation has been found to be one of the root causes of nearly every chronic disease known to mankind.  And thanks to the carnivore diets inflammation-lowering properties, this all-meat diet can aid in combating the development or worsening of chronic diseases like:

  • Cardiovascular conditions – like heart attacks and strokes
  • Autoimmune disorders
  • Metabolic disorders – like type 2 diabetes
  • Cancer
  • Neurodegenerative diseases – like dementia or Alzheimer’s
  • Infertility

The carnivore diet can be a powerful tool in preventing disease and promoting overall health and wellness.

The Carnivore Diet Can Elevate Your Energy Levels

Thanks to certain agricultural practices, an ever-increasing toxic burden, and a modern American diet that’s loaded with processed foods, many people are suffering from nutrient deficiencies and rampant inflammation. And this combination sets the stage for fatigue and less than ideal energy levels.

But the carnivore diet removes energy-depleting, inflammation-boosting foods and replaces them with nutrient-dense, energy-boosting foods. The carnivore diet boosts your levels of omega-3 fatty acids, protein, ketones, vitamin B, and carnitine – which are like super fuel for your brain and energy levels.

The Carnivore Diet Can Give You Glowing Skin

You’ve likely been sold the idea that in order to have a beautiful glowing complexion, you need to invest in expensive cleansers, creams, and moisturizers. But the truth is, truly healthy and beautiful skin starts from the inside out. Your skin is the largest organ of your body, so the quality of your diet is often directly reflected in the appearance of your skin.

The carnivore diet zaps inflammation and is full of copious amounts of nutrients your skin needs to thrive, which can improve skin issues like:

  • Acne
  • Fine lines and wrinkles
  • Dry flaky skin
  • Eczema or psoriasis
  • Redness and blotchiness
  • Puffiness    

By switching over to a carnivorous diet, you can address the root cause of your skin ailments – leaving you with an effortlessly radiant complexion.  

The Carnivore Diet Can Promote Healthy Sleep

Quality sleep is one of the core pillars of health and well-being. Without adequate amounts of high-quality sleep, your body simply can’t function at optimal capacity. And the carnivore diet can help you sleep better.

The carnivore diet eliminates the ups and downs in your blood sugar and energy levels – which can prevent you from tossing and turning and struggling to drift off to sleep. The carnivore diet is also loaded with nutrients that help balance hormones associated with a healthy sleep pattern like GABA and melatonin.

So, What Exactly Can You Eat on the Carnivore Diet?

Following the carnivore diet is about as uncomplicated as it gets. It doesn’t require counting calories or macros. And there’s no time wasted trying to figure out if something is “diet approved”. Carnivore approved foods are straightforward and include:

  • Meat – of any cut and any kind including beef, poultry, pork, and wild game
  • Fish and seafood – any kind is allowed 
  • Organ meats
  • Bone marrow and bone broth
  • Fatty meat products – like tallow or lard

The basics of the carnivore diet are simply meat and salt. And while chicken and poultry is certainly allowed, it’s best to keep these meats to a minimum as they tend to have an inferior fat and nutrient composition compared to things like beef, salmon, or wild game. 

Foods to Avoid on the Carnivore Diet

The carnivore diet is built entirely on meat – meaning it excludes all other foods including:

  • Fruits
  • Vegetables
  • Vegetable oils
  • Grains like rice, oats, barley, etc
  • Flour and flour products like bread, pasta, pastries, etc.
  • Chocolate (sorry)

And while things like hot dogs, salami, sausage, and other processed meats are technically meat, they are also a “no-go” on the carnivore diet. These modified meat products are typically chock-full of questionable ingredients and additives like nitrates and nitrites – so they don’t quite make the cut when switching to the carnivore diet.

Now this list might have you scratching your head thinking, “wait a second, I thought things like fruits and vegetables were supposed to be good for you?” So let’s take a look at why eating plants isn’t quite as healthy as you might think.

The Negative Effects of a Plant-Based Diet

We’ve all heard that fruits and vegetables are essential to a healthy diet. That they are packed full of health-boosting nutrients like essential vitamins and minerals, potent antioxidants, and gut-friendly fiber. But plants also have some other compounds that might not be so healthy.

You see, plants have evolved with their own survival at the top of their priority list. And since they can’t run away or fight off hungry grazers, they’ve developed their own defense mechanisms – minute amounts of poison. These natural plant toxins are designed to deter plant-eaters and include compounds such as:

  • Lectins
  • Phytates
  • Oxalates
  • Alkaloids
  • Glycosides
  • Tannins

Our bodies are designed to cope with small amounts of these toxins and certain cooking methods can significantly reduce levels of these toxins. But modern nutritional practices have most of us consuming massive amounts of plant-based foods – from fruits and veggies to grains, nuts, and bread. It’s estimated that on average, Americans eat about 1.5 grams of naturally occurring plant toxins each and every day.

To say that eating plants may actually be harmful to your health seems to defy conventional wisdom. But eating a diet that eliminates plants and consists exclusively of animals, is actually the secret sauce that can work wonders for your health. 

Below, you’ll see a quick overview of some common plant toxins and their possible effects.

How Much Am I Supposed to Eat on the Carnivore Diet?

One of the best aspects of following a carnivore diet is that there’s no tracking and no going hungry. Following the carnivore diet simply allows you to tune into your body and eat until your full – there are no rules about how many calories or servings you’re allowed to have. With that being said, the majority of carnivore dieters end up consuming between 1-2 pounds of meat a day – but most find it unnecessary to measure portions.

It’s also important to ensure you’re eating plenty of fat. Fat is essential because with too much protein and not enough fat, your body can actually manufacture glucose (a type of simple carbohydrate) from the protein in a process known as gluconeogenesis.  Simply ensuring you’re regularly incorporating fatty cuts of meat will prevent your body from converting protein into sugar.

Exactly When Am I Supposed to Eat on the Carnivore Diet?

There’s no right or wrong way to time your meals when following the carnivore diet, you can eat whenever you feel like it. But the carnivore diet does pair perfectly with another dietary practice that has some astounding health-boosting benefits – intermittent fasting. 

Intermittent fasting – or intermittent feasting as we like to call it – is simply cycling between periods of eating and fasting. That might mean fasting for 16 hours a day and allowing yourself an 8-hour eating window. Or you could follow a one meal a day (OMAD) intermittent feasting plan and pack all of your eating into a single meal. 

Combining the impressive benefits of intermittent fasting and the carnivore diet can pack a powerful punch when it comes to your health.

Carnivore Diet Meal Plan and Shopping List

Eating a strictly carnivorous diet makes your grocery hauls and meal planning about as easy as it gets. Take a look at the following charts to get a basic idea of what a weekly shopping list and meal plan might look like.

Does the Carnivore Diet Create Any Nutrient Deficiencies?

The answer to this question is – absolutely not! Trying to subsist strictly on one or two cuts of meat could potentially lead to nutritional deficiencies. But regularly rotating in a diverse range of animals, cuts of meat, and organs provides you with more than enough micronutrients to not only survive but thrive. 

In fact, one of the highlights of the carnivore diet is its impressive ability to reverse nutrient deficiencies. You see our digestive tracts and bodies still function the same way our primarily carnivorous ancestors did. We are designed to survive and flourish on one of the most nutrient-dense sources of fuel on the planet – meat.

Take a peek at the following charts to see exactly how our digestive tract is designed to support a meaty diet and to see the impressive nutritional profile of animal products versus plants.

Does Switching to the Carnivore Diet Have Any Side Effects?

Besides making vegan angels fall from heaven, likely nothing serious. Whether or not you have any negative side effects when switching to a carnivore diet will depend highly on your diet and lifestyle prior to making the transition. If you’re already eating a well-rounded low-carb diet, or following a ketogenic diet, chances are you won’t have many or any side effects.

But if you’re jumping into the carnivore diet straight from a diet high in carbohydrates and sugar, there’s a good chance you’re going to feel crummy before you feel better. As your body adjusts to having all carbs and sugar eliminated you may experience fatigue, headaches, and generally feeling “under the weather”.

But the good news is, this transition period typically only lasts anywhere from a few days to a couple of weeks. Once your body calibrates to your new and improved diet, you’ll start experiencing all of the positive benefits associated with an all-meat diet.

Carnivore Diet Frequently Asked Questions 

You might still have some unanswered questions when it comes to the carnivore diet. So let’s dive into some of the most commonly asked questions and address any doubts you might have about taking the plunge and jumping into an all-meat diet.

What About Fiber – Don’t I Need it?

The need for fiber is one of the most pervasive and harmful dietary myths. We’ve been indoctrinated with the misconception that the fiber found in plants and grains is essential to our health. But this couldn’t be further from the truth.

In fact, high fiber diets can:

  • Inhibit nutrient absorption
  • Disrupt your gut flora – leading to dysbiosis
  • Increase the risk of intestinal issues like diverticulitis and bloating

Switching to a low or no fiber diet can be one of the most beneficial things you can do for your health. So if you’re hesitant to switch to the carnivore diet because you’re worried about constipation or gut health – don’t be. Just take a look at the chart below to see the effects of reducing dietary fiber on your digestive tract.

Effects of Reducing Dietary Fiber

What About Vitamin C – Will I Get Enough on the Carnivore Diet?

The required daily intake for Vitamin C is vastly different for someone following a standard American diet and someone following a carnivore diet. That’s because glucose (sugar) and Vitamin C compete for absorption. What that means is if you don’t have any sugar in your diet, you have significantly more bioavailable Vitamin C.

So the Vitamin C you obtain from nutrient-dense organ meats will provide you with plenty of this essential vitamin when you don’t have a ton of sugar blocking your ability to utilize and absorb it.

Does the Carnivore Diet Put You in Ketosis? 

The answer is – it depends. Ketosis is a metabolic state that takes place when your body shifts into using fat as its primary source of fuel rather than carbohydrates. When your body doesn’t have any carbohydrates to burn for energy, your liver will begin oxidizing fatty acids – transforming them into molecules known as ketones, or ketone bodies, which serve as a form of energy.

Typically you will reach a state of ketosis in two ways: 

  • By fasting and limiting your intake of any fuel – thus forcing your body to use up your own stored fat as a source of energy
  • Consuming a diet consisting primarily of fat – forcing your body to rely on fat rather than carbs

Obviously consuming carbohydrates will quickly snap you out of ketosis. But too much protein can also shift your body out of a state of ketosis via gluconeogenesis.

So whether or not you enter a ketogenic state while following a carnivore diet will depend on exactly how much fat and protein you’re consuming. This can be a point of confusion between the carnivore diet and the ketogenic diet, so let’s take a little deeper look at the differences between these two.

What’s The Difference Between The Carnivore Diet and The Ketogenic Diet?

The carnivore diet is more restrictive and quite simple compared to the ketogenic diet. The carnivore diet focuses solely on eliminating all food sources that are not directly animal-based. 

The ketogenic diet, on the other hand, emphasizes the consumption of fat – from animal sources, but also plant sources like coconuts, avocados, and olive oil. The ketogenic diet has clear guidelines tracking and limiting the consumption of protein and carbohydrates. 

So while there can be some overlap between the two diets, and you will likely enter ketosis at times while following the carnivore diet, there is a distinct difference between these two ways of eating. 

Is the Carnivore Diet a Fad?

Definitely not! The carnivore diet isn’t something new and it’s definitely not a fad. It’s a way of eating that brings us back to our ancestral roots – back to the way our bodies are designed to function and flourish.

And the amount of science and personal testimonials touting the transformative power of the carnivore diet is growing exponentially. So you can be confident that the carnivore diet is here to stay and will only grow in popularity as more and more people tap into the ancient wisdom of how our bodies are designed to be fueled.

Can I Drink Coffee and Tea?

The answer is – it depends. While technically coffee and tea are allowed on the carnivore diet, it will depend largely on exactly how your body responds to these beverages. You see, coffee and tea can be pro-inflammatory and can lead to digestive issues like leaky gut syndrome.

It may take some trial and error to figure out what the amount and frequency of coffee and/or tea are right for your body. When switching to the carnivore diet, it may be a good idea to entirely eliminate coffee and tea and slowly add them back in to see how you feel. 

Are Dairy and Eggs Allowed?

Again, the answer is – it depends. Eggs and dairy tend to fall into a gray area when it comes to the carnivore diet. Technically things like eggs, butter, milk, cheese, and yogurt come from animal sources and are admissible. 

But the problem is, both dairy and eggs can be common allergens and can be pro-inflammatory. Anywhere from 1-3% of the population is allergic to egg whites and a much larger percentage of the population is intolerant to dairy. For this reason, many carnivore dieters limit or omit most egg and dairy products.

Is the Carnivore Diet Right for You?

While there’s certainly no “one size fits all” diet or approach to health, it’s hard to ignore the impressive and compelling benefits that have been linked to the carnivore diet. As the saying goes, the proof is in the pudding. And the copious amounts of science along with countless personal testimonials are proof that the carnivore diet is an all-out game-changer when it comes to your health. 

Whether you’re looking to shed a few pounds, boost your energy levels, or address an underlying health condition, the carnivore diet has got you covered. This meaty diet takes it back to the basics, powering your body with the fuel it’s designed to run on and subsequently supercharging your overall health and well being. So if you’re ready to take your health to the next level, then the carnivore diet just might be the perfect fit.
