The carnivore diet is a highly restrictive diet that consists of only animal products. This means meat, fish, eggs, animal fats, and small amounts of low-lactose dairy products are allowed, while all plant-based foods are excluded. The diet is claimed to promote weight loss and improve health issues such as heart health, autoimmune issues, blood sugar control, and mood. However, there is little scientific research to support these claims, and the diet contradicts most understandings of a healthy, balanced diet. The carnivore diet may also have negative health consequences, such as increased risk of kidney stones, gout, osteoporosis, and impaired kidney function.

Allowed foods: meat, fish, eggs, and small amounts of low-lactose dairy
The carnivore diet is a highly restrictive diet that consists of animal products only. It is a form of ketogenic diet, and works by eliminating all plant-based foods. The allowed foods on the carnivore diet include meat, fish, eggs, and small amounts of low-lactose dairy.
Meat is the primary component of the carnivore diet, with a focus on grass-fed and pasture-raised meats. This includes red meat such as steak, burgers, and chuck roast, as well as chicken, lamb, and pork. Organ meats, such as liver and oxtail, are also allowed and encouraged as they are rich in important nutrients.
Fish and seafood are also a part of the carnivore diet. Wild-caught seafood is recommended, and this can include salmon, trout, oysters, and clams, and even fish eyes and bone marrow.
Eggs are allowed on the carnivore diet, but in small amounts.
Small amounts of low-lactose dairy products are permitted on the carnivore diet. This includes hard cheese, butter, and cream.
The carnivore diet is promoted as a way to improve health and aid weight loss. However, there is limited scientific research to support these claims. The diet is high in fat and protein, and very low in carbohydrates, which can lead to feelings of fullness and reduced calorie intake. While some people may experience short-term weight loss, the diet is extremely restrictive and may not be sustainable or healthy in the long term. It contradicts the dietary guidelines that recommend a balanced diet with a variety of food groups, including fruits, vegetables, whole grains, and lean protein.

Excluded foods: fruits, vegetables, legumes, grains, nuts, and seeds
The carnivore diet is a highly restrictive diet that consists of only animal products. It is a form of ketogenic diet, and works by eliminating all plant-based foods and solely eating meat, fish, eggs, and small amounts of low-lactose dairy foods.
The diet excludes all plant-based foods, including fruits, vegetables, legumes, grains, nuts and seeds. Fruits such as apples, bananas, and oranges are off the menu, as are vegetables like broccoli, spinach, and carrots. Legumes, including beans, lentils, and peas, are also not permitted. This means that grains such as wheat, rice, and oats are excluded, and neither are nuts and seeds like almonds, walnuts, and sunflower seeds allowed.
These excluded food groups are typically recommended as part of a healthy, balanced diet. For example, fruits and vegetables are excellent sources of vitamins, minerals, and fiber. Legumes are a good source of plant-based protein and fiber, while grains provide essential carbohydrates, fiber, and B vitamins. Nuts and seeds offer healthy fats, protein, and a range of vitamins and minerals.
By cutting out these food groups, the carnivore diet may lead to nutrient deficiencies and an inadequate intake of fiber. This could potentially have negative consequences for digestive health and overall well-being. It is important to note that the exclusion of these food groups goes against the Dietary Guidelines for Americans, which recommend a balanced diet that includes fruits, vegetables, and whole grains.

Weight loss: likely to reduce calorie intake and burn fat
The carnivore diet is a highly restrictive diet that consists of only animal products. It includes meat, fish, eggs, and small amounts of low-lactose dairy. The diet is high in protein and natural fats, which promote satiety, making people feel fuller for longer and naturally reducing their overall calorie intake.
The carnivore diet is likely to reduce calorie intake and promote weight loss. This is because protein and fat help people feel more satisfied after meals, which may lead to reduced calorie intake and subsequent weight loss. Protein can also increase metabolic rate, helping to burn more calories.
The diet is also low in carbohydrates, which can promote weight loss. When the body does not have enough carbohydrates, it turns fat into ketones for energy instead. This may lead to increased fat burning and weight loss. Additionally, when people reduce their carbohydrate intake, their glycogen levels and stored water levels also decrease, which can lead to rapid weight loss in the first two weeks of a low-carb diet.
However, it is important to note that the carnivore diet is extremely restrictive and may not be sustainable or healthy in the long term. It contradicts most people's understanding of a healthy, balanced diet, which typically includes a variety of food groups such as fruits, vegetables, whole grains, and lean protein. Eliminating entire food groups can lead to nutrient deficiencies and is not recommended by dietary guidelines.
Furthermore, there is limited scientific research to support the claimed benefits of the carnivore diet. While some people may experience weight loss and improvements in certain health issues, there may also be unfavourable consequences for some individuals, especially over extended periods of time. It is always recommended to consult with a healthcare provider before starting any new diet.

Health risks: high protein intake may impair kidney function
The carnivore diet is a highly restrictive diet that consists of only animal products, including meat, fish, eggs, and small amounts of low-lactose dairy. It is promoted as a way to improve health and aid weight loss, but there is little scientific research to support these claims.
One of the potential health risks associated with the carnivore diet is the high intake of protein, which may impair kidney function. While high-protein diets are often recommended for weight loss and type 2 diabetes management, evidence suggests that they may negatively impact kidney health.
High dietary protein intake can lead to intraglomerular hypertension, resulting in kidney hyperfiltration, glomerular injury, and proteinuria. Over time, this can contribute to a decline in kidney function and an increased risk of chronic kidney disease (CKD). Several observational studies have found an association between high-protein diets and kidney function decline, particularly in individuals with pre-existing kidney issues or risk factors such as cardiovascular disease.
The quality of dietary protein also plays a role in kidney health. Animal protein, which is the primary source of protein in the carnivore diet, has been associated with an increased risk of end-stage kidney disease (ESKD) compared to protein from plant sources. Potential mediators of kidney damage from animal protein include dietary acid load, phosphate content, gut microbiome dysbiosis, and resultant inflammation.
Therefore, while the carnivore diet may promote weight loss and improve certain health markers, it is important to consider the potential risks associated with high protein intake, especially for those with impaired kidney function or risk factors for kidney disease.

Lack of evidence: no robust evidence of health benefits
The carnivore diet is a highly restrictive diet that consists of only animal products, including meat, fish, eggs, and small amounts of low-lactose dairy. It is claimed to promote weight loss and improve various health issues, such as heart health, autoimmune issues, blood sugar control, and mood. However, there is a lack of robust evidence supporting these purported health benefits.
Firstly, it is important to note that the carnivore diet does not align with the Dietary Guidelines for Americans, which recommend a balanced diet that includes fruits, vegetables, whole grains, and lean protein. By cutting out entire food groups, the carnivore diet may lead to nutrient deficiencies. For example, it lacks fiber and beneficial plant compounds such as antioxidants, vitamin C, and folate.
Secondly, while some studies have shown that high-protein and low-carb diets can promote weight loss in the short term, there is limited research specifically on the carnivore diet. One study by Baker surveyed over 2,000 people who followed the carnivore diet for 9 to 20 months. However, this study relied solely on self-reported data without measuring nutrient levels or health markers. Additionally, Baker's medical license was revoked in 2017 due to concerns about his competency, further calling into question the validity of the study.
Furthermore, the carnivore diet is difficult to follow long-term due to its lack of variety and restrictiveness. It may also be unsafe for certain populations, such as children, pregnant or lactating individuals, and those with a history of disordered eating. The very high protein intake associated with the carnivore diet can also lead to impaired kidney function. While some people report improvements in certain health markers, such as reduced BMI and improved blood sugar control, these findings may not be generalizable due to selection bias in the studies.
In conclusion, while there may be potential health benefits to the carnivore diet, there is currently a lack of robust evidence to support these claims. More controlled studies are needed to fully understand the short-term and long-term effects of this extremely restrictive dietary pattern. As always, it is important to consult with a healthcare professional before making any significant changes to your diet.
