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 premise of the diet is that by cutting out carbohydrates, the body will burn fat for energy, which will lead to weight loss. The diet was popularized by former orthopedic surgeon Shawn Baker, who wrote the book *The Carnivore Diet*. While some proponents claim that the diet can treat various health conditions, there is no clinical evidence that the carnivore diet provides any health benefits, and it has been criticized by dietitians and physicians as being potentially dangerous to health.

What You'll Learn
What foods can you eat?
The carnivorous diet is a highly restrictive diet that eliminates all food groups except animal products. This means that meat, poultry, fish, and seafood are all allowed. Some proponents of the diet also advocate for the inclusion of eggs and certain dairy products, while others recommend eliminating or limiting dairy to low-lactose options such as butter and hard cheeses.
Meat options can include red meat like steak, burgers, and chuck roast, as well as chicken, lamb, and pork. When it comes to seafood, salmon, trout, oysters, and clams are permitted. Organ meats such as liver and oxtail are also allowed. To cook your foods, you can use butter, fat tallow, or ghee, and seasonings such as salt, pepper, chilli paste, cumin, paprika, and garlic are allowed.
The carnivorous diet strictly excludes all fruits, vegetables, legumes, grains, nuts, and seeds. This means that you cannot consume any plant-based foods or products derived from plants, such as soybean or wheat. The diet also cuts out all carbohydrates, including highly processed carbohydrates such as cookies, cakes, pastries, candy, and sodas.
It is important to note that the carnivorous diet is not a well-studied or controlled diet, and there is limited research on its long-term effects. Some experts and dietitians have criticised it as a potentially dangerous fad diet that may lead to nutritional deficiencies and increased health risks. Therefore, it is always recommended to consult with a healthcare professional before starting any new diet, especially one that restricts entire food groups.

What foods are excluded?
The carnivorous diet is a highly restrictive diet that eliminates all food groups except animal products. This means that all fruits, vegetables, legumes, grains, nuts, and seeds are excluded.
Fruits and vegetables are an important source of micronutrients and dietary fiber, and their absence from the carnivorous diet may lead to constipation and other digestive issues. In addition, the high consumption of red meat associated with this diet increases the risk of colon cancer and gout.
The carnivorous diet also eliminates all grains, including wheat, which is one of the food items that commonly cause food sensitivities. The diet is also devoid of soybeans, which are a good source of plant-based nutrients.
The diet is very low in carbohydrates, which are the body's main energy source. Carbohydrates are converted into sugar (glucose) by the body and used for energy. By cutting out carbs, the body instead turns fat into ketones for energy, which can lead to weight loss. However, the carnivorous diet is not a healthy way to lose weight as it is low in beneficial nutrients and can be high in calories.
The carnivorous diet is not recommended for anyone with a chronic disease, such as diabetes or heart disease, or any level of kidney disease. It is also not suitable for those prone to disordered eating due to its restrictive nature and labeling of foods as "good" or "bad".

What are the claimed benefits?
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 Carnivore Diet is promoted as a way to improve overall health and well-being. Some proponents claim that it can treat a range of issues, including obesity, diabetes, depression, anxiety, arthritis, and more. The diet is also said to improve mental health, reduce inflammation, and lower blood sugar levels in people with diabetes.
The diet's creator, former orthopedic surgeon Shawn Baker, cites testimonials from followers of the diet as proof of its effectiveness. Baker claims that cutting out carbohydrates will speed up fat burning and weight loss, and that a carb-free diet will improve blood sugar control in people with type 2 diabetes.
Some people on the Carnivore Diet have reported benefits such as clearer skin, fewer migraines, increased energy, and weight loss. The diet is also said to be in line with the 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.
The Carnivore Diet is also promoted as a way to eliminate foods that commonly cause food sensitivities, such as nuts, wheat, and soybeans. It is also said to remove unhealthy, highly processed carbohydrates such as cookies, cakes, pastries, candy, and sodas from one's diet.
Additionally, the high protein content in the Carnivore Diet may lead to increased feelings of fullness, which may result in reduced calorie intake and subsequent weight loss. Protein can also increase metabolic rate, aiding in burning more calories.

What are the potential risks?
A carnivorous diet is an extreme form of a low-carb, high-fat diet that involves eating only animal products and foods derived from animals, including meat, fish, eggs, and certain dairy products. Those who follow this diet exclude all plant-based foods, such as fruits, vegetables, grains, legumes, nuts, and seeds.
Now, here are the potential risks of a carnivorous diet:
This diet restricts a wide variety of nutrient-dense plant foods, increasing the risk of nutritional deficiencies. Vitamins and minerals typically obtained from plant sources, such as vitamin C, folate, magnesium, and phytochemicals, are lacking in animal products. Long-term exclusion of plant foods may lead to scurvy, a deficiency of vitamin C, characterized by fatigue, weakness, and joint pain. Similarly, the low intake of folate can result in anemia and an increased risk of neural tube defects in pregnant women.
Another concern is the high saturated fat content in animal products, which can raise LDL ("bad") cholesterol levels, promoting the development of atherosclerosis (hardening and narrowing of the arteries) and increasing the risk of heart disease and stroke. Additionally, the absence of fiber in a carnivorous diet can lead to digestive issues, including constipation and an unhealthy gut microbiome, which is linked to various health problems, including inflammation and mental health disorders.
Following a carnivorous diet may also increase the risk of kidney damage due to the high protein intake, especially for those with existing kidney problems or those who are prone to kidney stone formation. This diet may also be socially isolating, as it severely limits food choices when eating out or socializing with others, potentially impacting an individual's quality of life and mental health.
Finally, there is a risk of developing an unhealthy relationship with food due to the restrictive nature of this diet. It may lead to disordered eating patterns, such as orthorexia, an unhealthy obsession with healthy eating, or an increased risk of developing an eating disorder. It is always advisable to consult a healthcare professional or a registered dietitian before starting any extreme diet to ensure it is safe and appropriate for your individual needs and health status.

What are the criticisms?
A carnivorous diet is a highly controversial way of eating that involves consuming only animal products and foods derived from animals, excluding all plant-based foods. This extreme approach to nutrition has sparked intense debate and attracted significant criticism from various quarters, including medical professionals, nutritionists, and ethical advocates.
Criticisms of the Carnivorous Diet:
One of the primary concerns regarding the carnivorous diet is the lack of scientific evidence supporting its supposed benefits. Proponents of this diet claim that it can improve health, enhance weight loss, and even cure chronic diseases. However, there is a dearth of scientific research and long-term studies specifically examining the effects of an exclusive animal-product diet in humans. Most of the assertions made by advocates are based on anecdotal evidence, personal testimonials, and short-term experiments, which are not sufficient to draw definitive conclusions. Without rigorous scientific scrutiny, it is premature and potentially dangerous to promote this diet as a panacea for various health issues.
The carnivorous diet also raises concerns about nutritional deficiencies. Plant-based foods are the primary sources of essential vitamins, minerals, antioxidants, and fiber. By eliminating all plant-derived foods, followers of this diet may miss out on the diverse range of nutrients that are vital for optimal health. For example, they may become deficient in vitamin C, which is abundant in citrus fruits and plays a crucial role in immune function and collagen synthesis. Similarly, the absence of plant sources may result in lower intakes of magnesium, potassium, and phytochemicals, all of which have been linked to reduced risk of chronic diseases.
Another criticism is the potential impact on gut health and the microbiome. The human gut is home to trillions of microorganisms that play a pivotal role in digestion, metabolism, and overall health. A diverse diet rich in plant fibers and nutrients is essential for nurturing a healthy gut microbiome. The carnivorous diet, devoid of any plant-based foods, may disrupt the delicate balance of gut bacteria and compromise digestive function. This could lead to issues such as constipation, diarrhea, and an increased risk of gut-related disorders.
Ethical and environmental concerns are also significant criticisms of the carnivorous diet. Animal agriculture, particularly the intensive farming of livestock, has a substantial environmental footprint. It contributes to land degradation, water usage, and greenhouse gas emissions. Encouraging a diet that relies solely on animal products could further exacerbate these environmental issues. Additionally, from an ethical perspective, the treatment of animals in industrial farming practices has long been a concern for animal welfare advocates. The promotion of a diet that exclusively consumes animal products may be seen as contributing to the exploitation and suffering of animals.
Finally, critics argue that the carnivorous diet is unsustainable and impractical for most people. It requires a significant departure from the standard dietary patterns and may be challenging to follow due to social, cultural, and economic factors. The cost of animal products tends to be higher than plant-based alternatives, making this diet financially inaccessible to many individuals and families. Additionally, the social aspects of sharing meals and cultural traditions often involve a variety of plant and animal-based dishes, and an exclusive carnivorous diet may hinder social interactions and limit culinary diversity.
In conclusion, while the carnivorous diet has its supporters, the criticisms outlined above highlight the potential risks and drawbacks of this extreme approach to nutrition. More scientific research is needed to fully understand the long-term effects of this diet on human health, and it is essential to approach such restrictive dietary practices with caution.
