The carnivore diet is a restrictive diet that consists of eating only meat, poultry, eggs, seafood, fish, and some dairy products. The diet excludes all other food groups, including fruits, vegetables, legumes, grains, nuts, and seeds. Proponents of the diet claim that it aids weight loss, improves heart health, and helps with blood sugar control and mood issues. However, there is no clinical evidence to support these claims, and the diet has been criticised by experts as being potentially unhealthy and unsustainable in the long term.

What You'll Learn
What can you eat?
The carnivore diet is a highly restrictive diet that consists of only animal products. This means that all foods that are not animal products are excluded from the diet. This includes fruits, vegetables, legumes, grains, nuts, and seeds.
More specifically, the carnivore diet includes meat, poultry, fish, eggs, and some dairy products. Some proponents of the diet recommend limiting dairy intake to low-lactose options such as butter and hard cheeses. The diet also includes seafood, although it is worth noting that the diet is not typical of the Inuit diet, which includes a high seafood content and the consumption of raw meat.
The carnivore diet is sometimes referred to as the "zero carb" diet because it aims to exclude all carbohydrates. This means that even carbohydrate-rich foods such as pasta, French fries, and doughnuts are excluded.
Some people following the carnivore diet may consume only beef, salt, and water, which is known as the "lion diet". This version of the diet has been described by experts as "potentially very unhealthy, difficult to follow, and unsustainable in the long term".
The carnivore diet is based on 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.

What can't you eat?
The carnivore diet is a very restrictive diet that only allows the consumption of animal products. This means that all plant-based foods are excluded.
Specifically, you cannot eat fruits, vegetables, grains, legumes, nuts, or seeds. This includes foods like french fries, doughnuts, and pasta. All drinks made from plants are also discouraged, such as tea and coffee.
In addition, some animal products are restricted on the carnivore diet. Dairy products, for example, should be limited due to their effects on inflammation. Only low-lactose dairy products, such as butter, sour cream, hard cheese, regular yogurt, and sherbet, are recommended.
The carnivore diet is a type of keto diet, which aims to reduce carbohydrate and glucose intake so that the body burns fat for energy instead. Therefore, any foods that are high in carbohydrates, such as bread, rice, and potatoes, are also excluded from the carnivore diet.
It is important to note that the carnivore diet is not backed by scientific research and may leave you low in certain nutrients. It is always recommended to talk to your doctor before starting any new diet, especially one that cuts out entire food groups.

What are the claimed benefits?
The carnivore diet is a highly restrictive diet that consists of only meat, poultry, eggs, seafood, fish, and some dairy products. All other food groups, including fruits, vegetables, legumes, grains, nuts, and seeds, are strictly excluded. 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.
The carnivore diet is claimed to provide numerous health benefits, including:
Weight Loss
The carnivore diet is promoted as a weight-loss method because it cuts out carbohydrates, which are the body's main energy source. When carbohydrates are not available, the body turns to burning fat for energy, leading to weight loss. Additionally, protein can help increase feelings of fullness after meals and boost metabolic rate, further contributing to reduced calorie intake and weight loss.
Improved Blood Sugar Control
Proponents of the carnivore diet claim that it can improve blood sugar control, especially in people with type 2 diabetes. By eliminating carbohydrates, the diet aims to stabilize blood sugar levels and reduce the need for diabetes medication.
Reduced Inflammation
The carnivore diet eliminates inflammatory foods like french fries, doughnuts, and pasta. As a result, it is believed to reduce inflammation in the body, although it is important to note that red meat itself can promote inflammation.
Improved Mental Health
Some advocates of the carnivore diet believe that it can improve mental health issues such as depression and anxiety. However, there is limited research to support this claim, and it is primarily based on testimonials from those following the diet.
Heart Health and Autoimmune Issues
The carnivore diet is also said to benefit heart health and autoimmune issues. However, there is no clinical evidence or controlled studies to support these claims, and the diet has been criticized by medical professionals as potentially dangerous to health.
It is important to consult with a healthcare professional before starting any restrictive diet like the carnivore diet, as it may lead to nutrient deficiencies and have potential negative consequences for overall health.

What are the potential risks?
The carnivore diet is a highly restrictive diet that eliminates all food groups except meat and other animal products, such as beef, chicken, pork, fish, and eggs. While proponents of the diet claim that it can promote weight loss and improve health conditions like type 2 diabetes, there are several potential risks associated with the carnivore diet.
Firstly, the diet is highly restrictive and eliminates highly nutritious foods like fruits, vegetables, legumes, and whole grains, which contain essential vitamins and minerals. This restriction can lead to deficiencies in some nutrients and the overconsumption of others. Diets rich in plant-based foods have been linked to a lower risk of certain long-term conditions like heart disease, certain cancers, Alzheimer's, and type 2 diabetes due to their high vitamin, fiber, and mineral content, as well as beneficial plant compounds and antioxidants. The carnivore diet lacks these compounds and has not been associated with any long-term health benefits.
Secondly, the carnivore diet can be high in saturated fat and cholesterol, which may increase the risk of heart disease. While recent studies have suggested that the link between saturated fat intake and heart disease risk may not be as strong as previously believed, the high levels of saturated fat and cholesterol in the carnivore diet are still a concern. Additionally, some processed meats contain high amounts of sodium, which can lead to excessive sodium intake and further increase the risk of high blood pressure and kidney disease.
Thirdly, the very high protein intake associated with the carnivore diet can have negative effects on gut health and kidney function. One review found that high-protein, low-carb diets may increase the risk of gut inflammation due to the creation of potentially harmful byproducts during the digestion of large amounts of protein. The diet may be especially harmful to certain populations, such as those with chronic kidney disease or those who are more sensitive to cholesterol in foods.
Furthermore, the carnivore diet may have negative environmental impacts. Research shows that red meat production significantly contributes to greenhouse gas emissions and greatly impacts global warming and climate change. Additionally, the diet may be difficult to maintain due to its restrictive nature, and there are concerns about its long-term health implications, such as an increased risk of colorectal cancer and heart disease. While some studies have reported improvements in overall health and chronic medical conditions, these studies have been short-term, and more research is needed to understand the long-term effects of the carnivore diet.

What do critics say?
Critics of the carnivore diet point to several potential health risks and negative side effects. The diet is considered extremely restrictive and likely unhealthy in the long term, as it cuts out entire food groups and may lead to nutrient deficiencies. Specifically, the diet lacks beneficial nutrients like vitamin C, folate, and fiber, and plant compounds like antioxidants.
The carnivore diet is also criticized for its potential impact on cardiovascular health. While it may aid in weight loss, the very high protein intake associated with the diet can lead to increased levels of LDL ("bad") cholesterol and impaired kidney function. The diet may also increase the risk of kidney stones, gout, and osteoporosis.
Critics also argue that the carnivore diet is not backed by scientific research. While some proponents of the diet claim that it can treat various health issues, including depression, anxiety, arthritis, obesity, and diabetes, there is little to no scientific evidence to support these claims. One study that surveyed individuals following the diet relied solely on self-reported data and did not measure nutrient levels or health indicators.
Additionally, critics argue that the carnivore diet is the exact opposite of the recommendations made by reputable health professionals. Instead of excluding plant-based foods, which are rich sources of vitamins, minerals, and fiber, health professionals generally encourage the consumption of a well-rounded diet that includes a variety of fruits, vegetables, and whole grains, along with lean protein from animal sources.
The carnivore diet is also criticized for being difficult to maintain and for potentially promoting misinformation about nutrition and health. Some experts warn against following this diet, especially for weight loss purposes, due to the potential health risks associated with it.
