The carnivore diet is a restrictive diet that consists of meat, fish, and other animal foods like eggs and some dairy products. It excludes all other foods, including fruits, vegetables, legumes, grains, nuts, and seeds. The diet is based on the controversial belief that ancestral populations ate mostly meat and fish, and that high-carb diets are responsible for today's high rates of chronic disease. While some proponents of the diet claim that it can aid weight loss and improve chronic diseases, there is little research to support these claims, and it may be difficult to follow long-term. The diet may also lead to nutritional deficiencies and has been linked to an increased risk of certain diseases. As such, it is important to carefully consider the potential benefits and risks before deciding whether or not to adopt the carnivore diet.

What You'll Learn
Weight loss
The carnivore diet is a highly restrictive diet that consists solely of animal products, including meat, poultry, eggs, seafood, fish, and some dairy products. It excludes all other food groups, such as vegetables, fruits, grains, legumes, seeds, and nuts, and is sometimes referred to as the "zero carb" diet.
Proponents of the carnivore diet claim that it promotes weight loss by cutting out calorie-dense, sugary junk foods and increasing protein and fat intake, which helps reduce hunger and lower overall calorie consumption. Additionally, the absence of carbohydrates in the carnivore diet forces the body to burn fat for energy, producing ketones that are released into the bloodstream, a state known as ketosis. This aspect of the diet is believed to enhance weight loss.
Some individuals who have followed the carnivore diet have reported substantial weight loss and improvements in their overall health and well-being. However, it is important to note that the carnivore diet is extremely restrictive and may not be sustainable or healthy in the long term. There is a lack of reliable research supporting the purported benefits of the carnivore diet, and it may lead to nutrient deficiencies and increased risk of certain health conditions, such as colorectal cancer and heart disease.
While the carnivore diet may lead to initial weight loss, it is not the only or necessarily the best method to achieve this goal. Other less restrictive diets, such as the keto diet, low-carbohydrate diets, the Mediterranean diet, and plant-based diets, have been shown to be effective for weight loss and are generally considered safer and easier to maintain. These diets emphasize a balanced intake of various food groups while still promoting weight loss and improving overall health.
Before embarking on any restrictive diet, it is essential to consult with a healthcare professional or a certified nutritionist to ensure it is safe and appropriate for your individual needs and health status.

Health benefits
The carnivore diet is a restrictive diet that consists of only 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 recommend eliminating or limiting dairy intake to low-lactose foods. The diet is based on the controversial belief that ancestral populations ate mostly meat and fish, blaming high-carb diets for today's chronic diseases.
The carnivore diet has been anecdotally linked to several health benefits, but there is limited scientific research to support these claims. Here are some of the potential health benefits:
Weight Loss: The carnivore diet may promote weight loss due to the high protein and fat content, which can suppress appetite and lead to reduced caloric intake. However, this weight loss may be short-lived and challenging to maintain in the long term due to the diet's restrictiveness.
Improved Gut Health: Some people report improved gut health and relief from gastrointestinal conditions while on the carnivore diet. This improvement may be due to the removal of food compounds that trigger physical symptoms, unintentionally mimicking the effects of an elimination diet. However, the carnivore diet lacks the gradual reintroduction of foods typically seen in elimination diets.
Reduced Inflammation: The carnivore diet eliminates inflammatory foods like french fries, doughnuts, and pasta. It also reduces inflammatory polyunsaturated fatty acids (PUFAs) from seed oils. However, red meat also promotes inflammation, and the overall impact on inflammation is not well-studied.
Increased Testosterone and Libido: The carnivore diet is rich in nutrients like cholesterol, protein, carnosine, carnitine, and vitamins K and D, which are essential for producing and maintaining healthy testosterone levels. A high-fat, low-fiber diet has been linked to higher testosterone levels in men.
Management of Diabetes: Some individuals with diabetes reported lowering their medication dosage or discontinuing it while on the carnivore diet. However, the study did not measure nutrient levels or health indicators, relying solely on survey responses. More research is needed to understand the impact on diabetes management.
It is important to consult with a healthcare professional before starting the carnivore diet or making any significant dietary changes. While it may offer potential benefits, it is highly restrictive and may not provide all the necessary nutrients for a balanced and healthy diet.

Nutritional deficiencies
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. The diet is based on the controversial belief that human ancestral populations ate mostly meat and fish and that high-carb diets are responsible for today's high rates of chronic disease.
The carnivore diet is unlikely to meet the nutritional needs of certain populations, including children and people who are pregnant or lactating. The diet is also not recommended for those with anxiety about food or a history of disordered eating.
The carnivore diet is extremely restrictive and does not offer much variety. It is high in fat, contains no fiber or beneficial plant compounds, and is difficult to maintain long-term. The diet may lead to nutritional deficiencies, especially in vitamin C, biotin, and folate. While vitamin C can be obtained from organ meats like spleen, thymus, and lung, the amount present in meat is generally very low, and the risks of eating raw meat to obtain this vitamin cannot be overstated.
Additionally, the carnivore diet does not align with the Dietary Guidelines for Americans, which recommend that adults obtain 45% to 65% of their daily calories from carbohydrates. The diet may also be deficient in vitamin A, which is important for the function of the eyes, heart, lungs, kidneys, and other organs. While vitamin A can be obtained from organ meats like liver, kidney, and sweetbreads, it is unclear if these foods are regularly consumed by those on the carnivore diet.

Environmental impact
The carnivore diet, which consists of eating only animal products, has been criticised for its negative environmental impact. This is due to the intensive animal production that is required to sustain the diet, which in turn causes significant environmental harm and raises ethical issues about animal treatment. Animal agriculture consumes vast amounts of land, water, and other resources, and contributes to deforestation. It also produces large amounts of methane and other greenhouse gases, which contribute to climate change.
Some proponents of the carnivore diet argue that intensive animal production is not inherently harmful to the environment and that, in fact, it is beneficial. They suggest that regenerative ranching and pasture-based agricultural systems can be beneficial to the environment. Additionally, they argue that plant agriculture is more destructive than raising animals, and that industrial-scale, commodity grain monoculture causes substantial environmental damage and loss of wildlife.
However, the majority view is that the environmental impact of the carnivore diet is negative. This is due to the high resource intensity of animal agriculture, which requires more land, water, and resources than plant agriculture. Additionally, the exclusion of all plant foods from the carnivore diet means that the environmental benefits of plant-based agriculture, such as the ability to grow plants for human consumption, are lost.
The environmental impact of the carnivore diet is further exacerbated by the health risks associated with the diet. The exclusion of fruits and vegetables from the diet can lead to nutritional deficiencies, including a lack of essential vitamins, antioxidants, and fibre. This can have long-term health consequences, such as an increased risk of chronic illnesses and cardiovascular disease. As a result, the carnivore diet may contribute to increased healthcare costs and resource usage, further adding to its environmental impact.
Overall, the carnivore diet is generally considered to have a negative environmental impact due to the intensive resource usage and environmental harm associated with animal agriculture, as well as the potential health risks and costs associated with the diet. While some argue that regenerative animal agriculture can be beneficial, the majority view is that plant-based agriculture is a more sustainable and environmentally friendly option.

Long-term health risks
The carnivore diet is a highly restrictive diet that consists entirely of meat and animal products, excluding all other foods. While it is claimed to aid weight loss, mood issues, and blood sugar regulation, among other health issues, there are several long-term health risks associated with the diet.
Firstly, the carnivore diet is low in vitamin C, folate, and fiber, and can lead to vitamin and mineral deficiencies. Without plant-based nutrients and other highly nutritious foods, it can be challenging to meet the daily intake of vitamins A, C, and B12, which contribute to optimal wellness. Diets rich in plant-based foods have been associated with a lower risk of certain long-term conditions such as Alzheimer's, heart disease, and Type 2 diabetes.
Secondly, the diet may harm your gut health and increase your risk of colorectal cancer. Consuming a large amount of animal protein can lead to unwanted stress on the kidneys, especially if you already have kidney issues. A diet high in red and processed meat has been linked to an increased risk of cancer, including colon and rectal cancer.
Thirdly, animal-based diets are high in saturated fat, which can raise low-density lipoprotein (LDL) cholesterol, increasing the risk of heart disease and stroke. Processed meats allowed on the diet are also high in salt, which can raise blood pressure.
Lastly, the highly restrictive nature of the carnivore diet makes it difficult to follow long-term. It eliminates many foods known to improve health and deliver essential nutrients, like fruits and vegetables. There is also a lack of research on the long-term effects of the carnivore diet, with no controlled studies to confirm its safety. While some studies have shown improvements in certain health markers, such as weight loss and blood sugar control, more research is needed to fully understand the long-term health implications of this diet.
