The carnivore diet is a highly restrictive diet that consists of animal products only, including meat, fish, eggs, and small amounts of low-lactose dairy. It is a form of ketogenic diet, which eliminates carbohydrates and replaces them with foods rich in fat and protein. The diet is claimed to promote weight loss and improve health issues such as heart health, autoimmune problems, blood sugar control, and mood. However, there is limited scientific research supporting these claims, and the diet contradicts dietary guidelines that recommend a balanced intake of fruits, vegetables, whole grains, and lean protein. While the carnivore diet may offer some benefits, it is important to approach it with caution and consult a healthcare provider before making any significant dietary changes.

Allowed foods: meat, fish, eggs, and small amounts of low-lactose dairy
The carnivore diet is a highly restrictive diet that consists of eating only meat, fish, and other animal products. It excludes all other food groups, including fruits, vegetables, legumes, grains, nuts, and seeds.
Meat, fish, and other animal products such as eggs and certain dairy products are allowed on the carnivore diet. This includes red meat like steak, burgers, and chuck roast, as well as chicken, lamb, and pork. Fish like salmon and trout are also allowed, as are seafood options such as oysters and clams. Organ meats, such as liver and oxtail, are also permitted. Eggs are allowed but should be consumed in small amounts.
When it comes to dairy, the carnivore diet recommends limiting intake to low-lactose options such as butter and hard cheeses. This is because lactose is a sugar found in milk and other dairy products that can have inflammatory effects on the body. By limiting dairy to low-lactose options, the diet aims to reduce potential inflammation.
It is important to note that the carnivore diet is considered extremely restrictive and may be challenging to follow long-term due to the limited variety of foods allowed. It is always recommended to consult with a healthcare professional before starting any new diet, especially one as restrictive as the carnivore diet.

Excluded foods: all plant-based foods, nuts, seeds, legumes, grains, and fruits
The carnivore diet is a highly restrictive diet that cuts out all plant-based foods, including fruits, vegetables, legumes, grains, nuts, and seeds. This means that popular plant-based foods like avocados, quinoa, and almonds are off the menu. The diet also excludes foods derived from plants, such as vegetable oils, soy products like tofu, and plant-based milk alternatives.
The focus of the carnivore diet is on animal-based foods, specifically meat, fish, and other animal products. This includes red meat like steak, beef, lamb, and pork, as well as poultry like chicken and turkey. Seafood is also a significant part of the diet, with fish like salmon and trout, and shellfish like oysters and clams being recommended. Those on the carnivore diet can also consume animal products like eggs, butter, and certain dairy products.
While dairy is allowed, proponents of the diet recommend limiting it to low-lactose options such as butter, ghee (clarified butter), and hard cheeses. This is because lactose is a sugar found in milk and other dairy products, and the carnivore diet aims for zero carbs. Dairy products like milk and yogurt are high in lactose and therefore not encouraged.
The carnivore diet stems from the controversial belief that human ancestral populations ate mostly meat and fish, and that the high-carb diets of today are to blame for the high rates of chronic disease. By cutting out all carbs, the diet claims to promote weight loss and improve health. However, it is important to note that the carnivore diet is not well-studied, and there is limited research to support its claimed benefits.
The exclusion of plant-based foods and the focus on animal-based products make the carnivore diet extremely restrictive and potentially lacking in certain nutrients. It is always recommended to speak to a healthcare professional before starting any new diet, especially one as restrictive as the carnivore diet.

Potential benefits: weight loss, improved heart health, better blood sugar control
The carnivore diet is a highly restrictive diet that involves cutting out all carbohydrates and eating only meat and other animal products, such as beef, chicken, pork, fish, and eggs. This diet is based on the idea that by eliminating carbohydrates, the body will burn fat for energy and promote weight loss. While some people have reported successful weight loss on this diet, it is important to note that the weight loss may be short-lived and difficult to maintain in the long term due to the restrictiveness of the diet.
Proponents of the carnivore diet also claim that it can lead to improved heart health. However, there is limited research to support this claim, and some evidence suggests that diets high in animal products and low in plant-based foods may increase the risk of cardiovascular disease (CVD). Plant-based diets, on the other hand, have been strongly associated with a reduced risk of CVD.
One of the most controversial aspects of the carnivore diet is its potential impact on blood sugar control. Some people with diabetes have reported lower glucose levels and improved blood sugar management by following this diet. However, most experts advise against the carnivore diet for people with diabetes. Additionally, a 2018 study found that high consumption of red and processed meat is linked to nonalcoholic fatty liver disease and insulin resistance, which are concerns for individuals with diabetes.
While the carnivore diet may offer some potential benefits, it is important to approach it with caution. The diet lacks certain nutrients and has been associated with long-term health risks, including an increased risk of kidney stones, gout, and osteoporosis. As with any diet, it is essential to consult with a healthcare professional before making significant dietary changes, especially for those with pre-existing health conditions.

Potential risks: increased risk of kidney stones, gout, osteoporosis, impaired kidney function
The carnivore diet is a restrictive eating plan that involves consuming only animal products, including meat, eggs, and some variations of dairy products like cheese and milk. This diet excludes all plant-based foods, including fruits, vegetables, grains, nuts, and seeds. Proponents of the diet claim that it supports weight management, improves mental clarity, and promotes better digestive health due to the elimination of potentially inflammatory plant compounds and fibers.
However, there are potential risks associated with the carnivore diet, including an increased risk of kidney stones, gout, osteoporosis, and impaired kidney function. Firstly, regarding kidney stones, the high protein intake associated with the carnivore diet may lead to an increased risk of kidney stone formation. While there is limited direct evidence linking the carnivore diet to kidney stone development, the high protein content can result in increased uric acid levels, which is a risk factor for kidney stone formation.
Secondly, the carnivore diet's high intake of animal proteins, which are rich in purines, has been linked to an increased risk of gout. Gout is a form of painful arthritis caused by an acute inflammatory response to the accumulation of urate crystals in the joints. The excess of uric acid, a byproduct of purine metabolism, can overwhelm the kidneys' ability to remove it, leading to crystallization and subsequent joint deposition, triggering gout symptoms. However, it is important to note that the low-carb nature of the carnivore diet might also mitigate some risk factors for gout, making the relationship complex.
Thirdly, the exclusion of plant-based foods in the carnivore diet may contribute to an increased risk of osteoporosis. Plant-based foods are rich sources of calcium and nutrients essential for bone health. By eliminating these sources, the carnivore diet may negatively impact bone mineral density and increase the risk of osteoporosis. However, the specific link between the carnivore diet and osteoporosis requires further investigation.
Lastly, the very high protein intake associated with the carnivore diet has raised concerns about impaired kidney function. The kidneys play a crucial role in filtering out nitrogen and byproducts from protein metabolism. While studies show that increased protein intake does not harm individuals with normal kidney function, there is some evidence that it can lead to "hyperfiltration," putting a strain on the kidneys and potentially causing damage over time. However, it is important to note that the greatest risk factors for kidney disease are chronic inflammatory conditions linked to high-carb, modern diets, and the carnivore diet's low-carb nature may actually reduce these risk factors.

Criticisms: lacks scientific evidence, excludes food groups known to be beneficial, unsustainable
The carnivore diet is a highly restrictive diet that consists of only animal products, including meat, fish, eggs, and some low-lactose dairy. It excludes all other food groups, such as fruits, vegetables, legumes, grains, nuts, and seeds. The diet is based on the controversial belief that human ancestral populations consumed mostly meat and fish, and that high-carb diets are responsible for today's high rates of chronic diseases.
Criticism: Lacks Scientific Evidence
The carnivore diet has been criticized for lacking scientific evidence and long-term research to support its purported benefits. There is limited research on the carnivore diet, and the few studies that exist are based on surveys and self-reported data from followers of the diet. The highly restrictive nature of the diet makes it challenging to follow long-term, and there are concerns about potential adverse health effects.
Criticism: Excludes Food Groups Known to be Beneficial
The carnivore diet excludes several food groups known to provide essential nutrients and health benefits. By eliminating fruits and vegetables, the diet lacks fiber, which is crucial for gut health. It also misses out on carotenoids and polyphenols, substances with antioxidant properties linked to a lower risk of chronic diseases such as Type 2 diabetes and certain cancers. The diet is also low in vitamin C and folate, which are essential for overall health and well-being.
Criticism: Unsustainable
The carnivore diet has been criticized for being unsustainable due to the environmental impact of industrial animal agriculture. The large-scale production of animal-based foods contributes to climate change, particularly in the Global North, where meat consumption is high. Additionally, the diet may be challenging to maintain due to its restriction of food choices, making it difficult to follow long-term.
