The Carnivore Diet Exposed: Shocking Benefits, Hidden Risks, and What You Must Know Before Trying It!

The carnivore diet, a highly restrictive eating plan centered around animal products, has garnered attention as a potential route to weight loss and improved health. This article examines the carnivore diet, exploring its principles, purported benefits, potential risks, and overall sustainability.

What is the Carnivore Diet?

The carnivore diet, also known as the "zero carb" diet, is a restrictive eating plan that involves consuming only animal products, such as meat, fish, eggs, and limited amounts of certain dairy items. It excludes all plant-based foods, including fruits, vegetables, grains, legumes, nuts, and seeds. In essence, it's a more restrictive version of the ketogenic diet, emphasizing fat and protein while minimizing carbohydrates.

Foods Allowed

The carnivore diet menu typically includes:

Beef, pork, poultry, and other meats
Fish and seafood
Wild game (e.g., venison)
Eggs
Limited full-fat dairy products (e.g., cheese and butter)
Water

Some proponents allow salt, pepper, and seasonings with no carbs.

Foods Excluded

The carnivore diet excludes all foods that do not come from animals:

Vegetables (e.g., broccoli, cauliflower, potatoes)
Fruits (e.g., apples, berries, bananas)
High-lactose dairy (e.g., milk, yogurt, soft cheese)
Legumes (e.g., beans, lentils)
Nuts and seeds (e.g., almonds, pumpkin seeds)
Grains (e.g., rice, wheat, bread)
Alcohol (e.g., beer, wine, liquor)
Sugars (e.g., table sugar, maple syrup)
Beverages other than water (e.g., soda, coffee, tea, fruit juice)

Origins and Popularity

The carnivore diet's roots can be traced to ancestral eating patterns, with proponents arguing that early humans thrived primarily on animal-based diets. Many say it reflects the natural way our ancestors ate. It has gained traction through books and social media influencers, but meat-only diets have been touted for hundreds of years.

Purported Benefits of the Carnivore Diet

Advocates of the carnivore diet claim several potential benefits, often supported by anecdotal accounts. Scientific research specific to this eating plan remains limited.

Weight Loss: By eliminating carbohydrates, the body enters a state of ketosis, burning fat for fuel. This can lead to increased metabolism and weight loss. High-protein diets can also promote satiety, reducing overall calorie intake.
Blood Sugar Management: The carnivore diet can stabilize blood sugar levels by preventing the spikes that occur after consuming carbohydrates or sugary foods.
Chronic Disease Control: Some believe that by taking carb count to zero it addresses that specific risk factor from high-carb diet, particularly from sugars, links to various chronic diseases.
Better Mental Health: Some studies connect meat consumption to lower rates of depression and anxiety. Many also talk of achieving greater mental clarity while on a carnivore diet.
Simplified Eating Habits: With no need to count calories or worry about food variety, some find the diet easier to follow.

Potential Risks and Drawbacks

Going to a meat-based diet can bring side effects that negatively affect your health. The carnivore diet raises several health concerns due to its restrictive nature and high intake of animal products.

Heart Disease: The carnivore diet is high in saturated fats that can raise your "bad cholesterol" (LDL) levels and put you at higher risk for heart disease. The American Heart Association recommends limiting red meat to protect your ticker.
Cancer: Eating large amounts of red meat has been linked to increased risk for colorectal cancer, which can be divided into colon cancer and rectal cancer, as well as several other types of cancer.
Nutrient Deficiencies: A meat-only diet lacks essential vitamins and minerals found in plant-based foods, such as fiber, vitamin C, and antioxidants, which are crucial for gut and immune health. When you omit entire food groups from your diet, there are consequences.
Digestive Problems: Meat takes longer to digest, and slowing down that process can lead to constipation. Plus, the carnivore diet lacks fiber to help keep things moving along. The lack of fiber can lead to constipation and disruptions in gut microbiome diversity, essential for digestion and overall well-being.
Muscle Cramps: The lack of key nutrients in a meat-based diet can lead to electrolyte imbalances that cause muscle cramps, as well as dizziness, fatigue, and general weakness.
Kidney Function: Eating a diet high in animal protein can place added stress on your kidneys, which may affect their long-term filtering function. Eating more meat also may contribute to kidney stone formation.
Long-Term Sustainability: Cutting out entire food groups can make it difficult to maintain balanced eating habits over time, potentially leading to disordered eating patterns.
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. 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.
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. Following a restrictive diet like the carnivore diet may lead to deficiencies in some nutrients and the overconsumption of others. 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. The carnivore diet does not contain these compounds and has not been associated with any long-term health benefits.
Does Not Provide Fiber: Thus, the carnivore diet contains no fiber, which may lead to constipation as a side effect. 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.
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.

The Carnivore Diet and Long-Term Wellness

One of the biggest concerns about the carnivore diet is whether it supports long-term health. The absence of plant-based foods raises concerns about deficits in fiber and phytonutrients that support heart health, digestion, and disease prevention.

Research Findings

A social media survey conducted in 2020 among adults consuming a carnivore diet for at least six months revealed that participants reported high levels of satisfaction and improvements in overall health. The study indicated that participants experienced few adverse effects and reported health benefits. However, LDL-cholesterol was markedly elevated among a subset reporting current lipids.

Is the Carnivore Diet Worth Trying?

The carnivore diet offers short-term benefits for some individuals, but its long-term health effects remain largely unknown, and it comes with potential risks such as nutrient deficiencies and cardiovascular concerns. Instead of extreme dietary restrictions, prioritizing high-quality protein sources while incorporating nutrient-rich plant foods for overall wellness is a more sustainable approach for your long-term health.

There may be some benefit in limiting carbs, especially simple carbs high in added sugar (like white bread and baked goods). But it’s not ideal for your body to cut out all carbs.

The key is moderation. Focus on filling your plate with a range of whole foods like fruits, vegetables, grains, and lean meats.
