Carnivore Diet Review: Benefits, Downsides, and Sample Menu (2024)

No controlled studies support claims that the carnivore diet can help eliminate health issues. It lacks beneficial nutrients, including fiber and plant compounds like antioxidants. It may be unsafe for some people.

The carnivore diet consists entirely of meat and animal products, excluding all other foods.

It’s claimed to aid weight loss, mood issues, and blood sugar regulation, among other health issues.

However, the diet is extremely restrictive and likely unhealthy in the long term. Plus, no research backs its purported benefits.

The carnivore diet eliminates all foods except meat and animal products. Thus, it’s lacking in numerous nutrients like fiber, loaded with salt and fat, and difficult to maintain. You should follow a well-rounded diet instead.

This article reviews the carnivore diet, including what the diet includes, whether it can aid weight loss, and its potential benefits and downsides.

Carnivore Diet Review: Benefits, Downsides, and Sample Menu (1)Share on Pinterest

The carnivore diet is a restrictive diet that only includes meat, fish, and other animal foods like eggs and certain dairy products.

It excludes all other foods, including fruits, vegetables, legumes, grains, nuts, and seeds.

Its proponents also recommend eliminating or limiting dairy intake to foods that are low in lactose — a sugar found in milk and dairy products — such as butter and hard cheeses.

The carnivore diet stems from the controversial belief that human ancestral populations ate mostly meat and fish and that high-carb diets are to blame for today’s high rates of chronic disease.

Other popular low-carb diets, like the keto and paleo diets, limit but don’t exclude carb intake. However, the carnivore diet aims for zero carbs.

Shawn Baker, an American orthopedic doctor, is the most well-known proponent of the carnivore diet (1).

He cites testimonials from those who follow the carnivore diet as proof that it can treat depression, anxiety, arthritis, obesity, diabetes, and more (1).

However, no controlled studies have analyzed the effects of the carnivore diet.

One study promoted by Baker asked followers of the diet to fill out a survey on their eating habits and health. The respondents reported satisfaction and beneficial effects (2).

However, nutrition experts raised concerns about the study’s health claims. For example, the study did not include any way to check the accuracy of the health information submitted by the respondents. The results should be interpreted with caution (3).

What’s more, in 2017 Baker’s medical license was revoked by the New Mexico Medical Board due to concerns about his competency. Baker’s medical license was reinstated in 2019 with a requirement for direct supervision when practicing medicine (4, 5).


The carnivore diet excludes all foods except meat, eggs, and small amounts of low-lactose dairy products. Testimonials from those who follow the diet claim that it can help treat several health issues, but no research supports these claims.

Following the diet involves eliminating all plant foods from your diet and exclusively eating meat, fish, eggs, and small amounts of low-lactose dairy products.

Foods to eat include beef, chicken, pork, lamb, turkey, organ meats, salmon, sardines, white fish, and small amounts of heavy cream and hard cheese. Butter, lard, and bone marrow are also allowed.

Proponents of the diet emphasize eating fatty cuts of meat to reach your daily energy needs.

The carnivore diet encourages drinking water and bone broth but discourages drinking tea, coffee, and other drinks made from plants.

Carnivore diet plans may offer little guidance regarding calorie intake, serving sizes, or how many meals or snacks to eat per day. Most proponents of the diet suggest eating as often as you desire.


Following the carnivore diet involves eating only meat, fish, and animal products, eliminating all other foods. It may not include details such as calorie intake, serving size, or meal timing.

Certain aspects of the carnivore diet may lead to weight loss. Specifically, some studies have shown that high-protein and low-carb diets can promote weight loss (6, 7, 8).

This is mostly because protein can help you feel more full after meals, which may lead to reduced calorie intake and subsequent weight loss. Protein can also increase your metabolic rate, helping you burn more calories (9, 10, 11).

Therefore, following the carnivore diet would likely cause you to feel fuller and eat fewer calories overall — at least in the short term.

One 3-month study in 132 adults with excess weight or obesity compared the weight loss effects of 4 energy-restricted diets containing varying amounts of carbs and protein (6).

Those who ate high-protein diets with 0.4–0.6 grams of protein per pound (0.9–1.3 grams per kilogram) of body weight per day lost significantly more weight and fat mass than those who ate 0.2–0.4 grams of protein per pound (0.5–0.9 grams per kilogram) of body weight per day (6).

Other studies show similar results, suggesting that increasing protein intake may lead to weight loss and help reduce the amount of weight regained over time (12).

However, you don’t need to cut all carbs from your diet to see results. Reducing your overall calorie intake, which may be easier to do with a higher intake of satisfying protein, is the main driver of weight loss (12).

Plus, the highly restrictive nature of the carnivore diet makes it difficult to follow long term.


Increasing your protein intake and reducing your carb intake may help you lose weight. That said, the extremely high amounts of protein and complete elimination of carbs on the carnivore diet are not necessary to lose weight.

Since the carnivore diet excludes carbs, it eliminates cookies, cakes, candy, sodas, pastries, and similar high-carb foods.

These foods are low in beneficial nutrients and often high in calories. Thus, they should be limited in a healthy, balanced diet.

High-sugar foods can also be problematic for people with diabetes, as they can spike blood sugar levels. In fact, limiting refined carbs and sugary foods is often recommended to control diabetes (13).

However, the complete elimination of carbs on the carnivore diet is not recommended or necessary for diabetes management. Instead, eating smaller amounts of wholesome, high-fiber carbs that don’t cause spikes in blood sugar is recommended (13).


The carnivore diet does not include refined carbs or sugary foods, which can spike your blood sugar levels. Still, completely avoiding carbs is not necessary to control your blood sugar.

Due to its highly restrictive nature and complete elimination of the majority of food groups, there are many downsides to the carnivore diet.

High in fat, cholesterol, and sodium

Given that the carnivore diet consists solely of animal foods, it can be high in saturated fat and cholesterol.

Saturated fat may raise your LDL (bad) cholesterol, which may increase your risk of heart disease (13).

However, recent studies have shown that the link between saturated fat intake and heart disease risk may not be as strong as previously believed (14, 15).

Still, consuming high amounts of saturated fat on the carnivore diet may be of concern. No research has analyzed the health effects of eating animal foods exclusively. Therefore, the effects of consuming such high levels of fat and cholesterol are unknown.

Moreover, some processed meats, especially bacon and breakfast meats, also contain high amounts of sodium.

Eating a lot of these foods on the carnivore diet can lead to excessive sodium intake, which has been linked to an increased risk of high blood pressure, kidney disease, and other negative health outcomes (16).

Red and processed meat intake has also been linked to higher rates of certain types of cancer, including colon and rectal cancer (17).

May lack certain micronutrients and beneficial plant compounds

The carnivore diet eliminates highly nutritious foods like fruits, vegetables, legumes, and whole grains, all of which contain beneficial vitamins and minerals.

While meat is nutritious and provides micronutrients, it should not be the only part of your diet. Following a restrictive diet like the carnivore diet may lead to deficiencies in some nutrients and the overconsumption of others (18).

What’s more, diets that are rich in plant-based foods have been associated with a lower risk of certain long-term conditions like heart disease, certain cancers, Alzheimer’s, and type 2 diabetes (19, 20, 21).

This is not only due to the high vitamin, fiber, and mineral contents of plant foods but also their beneficial plant compounds and antioxidants (20).

The carnivore diet does not contain these compounds and has not been associated with any long-term health benefits.

Does not provide fiber

Fiber, a non-digestible carb that promotes gut health and healthy bowel movements, is only found in plant foods (22).

Thus, the carnivore diet contains no fiber, which may lead to constipation as a side effect (23).

Additionally, fiber is incredibly important for the proper balance of bacteria in your gut. In fact, suboptimal gut health can lead to a number of issues and may even be linked to colon cancer (24, 25).

In fact, one review found that a high-protein, low-carb diet may increase your risk for gut inflammation. When your body digests large amounts of protein, it creates potentially harmful byproducts in your gut. These byproducts may have a negative effect on the health of your bowels (26).

Overall, following the carnivore diet may harm your gut health.

May not be suited for some populations

The carnivore diet may be especially problematic for certain populations.

For example, those who need to limit their protein intake, including people with chronic kidney disease, should not follow the diet (27).

Also, those who are more sensitive to the cholesterol in foods, or cholesterol hyper-responders, should be cautious about consuming so many high-cholesterol foods (28).

Furthermore, certain populations with special nutrient needs would likely not meet them on the carnivore diet. This includes children and people who are pregnant or lactating.

Lastly, those who have anxiety about food or a history of disordered eating should not try this diet.


The carnivore diet is high in fat and may contain excessive amounts of sodium. It contains no fiber or beneficial plant compounds and may provide inadequate amounts of certain nutrients.

The carnivore diet includes only animal products and excludes all other foods.

Specifically, someone on the carnivore diet can eat:

  • Meat: beef, chicken, turkey, organ meats, lamb, pork, etc.
  • Fish: salmon, mackerel, sardines, crab, lobster, tilapia, herring, etc.
  • Other animal products: eggs, lard, bone marrow, bone broth, etc.
  • Low-lactose dairy (in small amounts): heavy cream, hard cheese, butter, etc.
  • Water

According to some proponents of the diet, salt, pepper, and seasonings with no carbs are allowed.

In addition, some people choose to eat yogurt, milk, and soft cheese, but these foods are typically not included due to their carb contents.


Foods allowed on the carnivore diet include all meats and fish, eggs, bone marrow, butter, and lard, as well as small amounts of hard cheese and heavy cream.

All foods that do not come from animals are excluded from the carnivore diet.

Restricted foods include:

  • Vegetables: broccoli, cauliflower, potatoes, green beans, peppers, etc.
  • Fruits: apples, berries, bananas, kiwi, oranges, etc.
  • High-lactose dairy: milk, yogurt, soft cheese, etc.
  • Legumes: beans, lentils, etc.
  • Nuts and seeds: almonds, pumpkin seeds, sunflower seeds, pistachios, etc.
  • Grains: rice, wheat, bread, quinoa, pasta, etc.
  • Alcohol: beer, wine, liquor, etc.
  • Sugars: table sugar, maple syrup, brown sugar, etc.
  • Beverages other than water: soda, coffee, tea, fruit juice, etc.

While some people incorporate some of these foods, a strict carnivore diet does not permit them.


Foods that do not come from animals are completely excluded, including vegetables, fruits, high-lactose dairy, legumes, nuts, seeds, grains, alcohol, coffee, tea, and juices.

The carnivore diet is difficult to follow long term and does not offer much variety.

Here’s a five-day sample menu for the carnivore diet:

Day 1

  • Breakfast: eggs, bacon, sardines
  • Lunch: turkey burger patty, salmon jerky, beef tips
  • Dinner: filet mignon, crab, chicken liver
  • Snacks: a small amount of Parmesan cheese, jerky

Day 2

  • Breakfast: shrimp, eggs, a small glass of heavy cream
  • Lunch: strip steak, tuna fish, beef jerky
  • Dinner: lamb chops, scallops, beef liver
  • Snacks: a small amount of hard Cheddar cheese, bone broth

Day 3

  • Breakfast: eggs, salmon, turkey sausage
  • Lunch: beef tips, pork chops, mackerel
  • Dinner: turkey burger patty, a small amount of Parmesan cheese, bone marrow
  • Snacks: hard-boiled eggs, shrimp

Day 4

  • Breakfast: trout, shredded chicken, bacon
  • Lunch: beef meatballs, small amount Cheddar cheese, salmon jerky
  • Dinner: crab cooked in lard, filet mignon
  • Snacks: sardines, beef jerky

Day 5

  • Breakfast: eggs, chicken and turkey sausage links
  • Lunch: lamb roast, chicken liver, pork chop
  • Dinner: flank steak, scallops cooked in butter, a small glass of heavy cream
  • Snacks: bone broth, turkey jerky

Meals and snacks on the carnivore diet consist entirely of animal products and offer little variety.

The carnivore diet is extremely restrictive, consisting entirely of meat, fish, eggs, and small amounts of low-lactose dairy.

It’s said to aid weight loss and several health issues, but no reliable research backs these claims.

What’s more, it’s high in fat and sodium, contains no fiber or beneficial plant compounds, and is difficult to maintain long term.

Overall, the carnivore diet is unnecessarily restrictive. Eating a balanced diet with a variety of healthy foods is more sustainable and will likely afford you more health benefits.
