Carnivore Diets: Do Plants Have A Place?

The carnivore diet is a restrictive diet that consists entirely of meat, fish, and other animal products, excluding all other foods. This means that the diet cuts out all fruits and vegetables, legumes, grains, nuts, and seeds. The diet is similar to the ketogenic (keto) and Atkins diets, which also limit carbs, but the carnivore diet cuts out all carbohydrates. The diet is considered unbalanced and unlikely to be healthy in the long term due to the exclusion of many healthy food groups. There is also a lack of robust evidence to support the claimed benefits of the diet, and it may lead to nutritional deficiencies.

The carnivore diet is a type of keto diet

The carnivore diet is a highly restrictive diet that involves eating only meat and animal products, such as beef, chicken, fish, and eggs, while excluding all other food groups, including fruits, vegetables, legumes, grains, nuts, and seeds. This diet is based on the controversial belief that human ancestral populations primarily consumed meat and fish, and that high-carb diets are responsible for today's high rates of chronic disease.

The carnivore diet is indeed a type of keto diet, or ketogenic diet. Keto diets are characterized by significantly reducing carbohydrate intake, which forces the body to burn fat for energy instead of glucose. This process, known as ketosis, involves the body burning fat and creating ketones as an energy source, resulting in a more acidic blood state. While standard keto diets typically allow for a small percentage of carbohydrates, the carnivore diet aims for zero carbs. As a result, it is considered the most ketogenic diet.

The carnivore diet, as a form of keto, shares some similarities with other keto diets such as the Atkins diet. However, the key distinction is that while keto and Atkins diets limit carbs, the carnivore diet completely eliminates them. This makes the carnivore diet much more restrictive than other keto diets.

By following the carnivore diet, proponents claim that individuals can experience weight loss, improved heart health, better blood sugar control, and enhanced mental health. However, it's important to note that these claims are largely based on anecdotal evidence and lack scientific research to support them.

Furthermore, the carnivore diet, like other keto diets, tends to raise LDL ("bad") cholesterol levels due to the high consumption of animal fat, which is mostly saturated fat. Additionally, the long-term concerns associated with keto diets, such as an increased risk of kidney stones, gout, and osteoporosis, also apply to the carnivore diet. The very high protein intake associated with the carnivore diet can also lead to impaired kidney function.

In conclusion, while the carnivore diet may lead to weight loss and have certain purported benefits, it is an extremely restrictive form of the keto diet that may lead to nutritional deficiencies and potential health risks. As always, it is important to consult with a healthcare professional before starting any new diet, especially one as restrictive as the carnivore diet.

It's high in protein and fat, and very low in carbohydrates

The carnivore diet is a highly restrictive diet that consists of eating only meat and animal products, such as beef, chicken, pork, fish, and eggs, while excluding all other food groups, including fruits, vegetables, legumes, grains, nuts, and seeds. This diet is sometimes referred to as the "zero-carb" diet, as it aims to cut out all carbohydrates.

The carnivore diet is high in protein and fat, with animal products being the primary source of calories. The diet recommends eating fatty cuts of meat to meet daily energy needs and organ meats, such as liver, to ensure adequate intake of vitamins that may be lacking in other cuts of meat.

By eliminating carbohydrates, the carnivore diet claims to promote weight loss by speeding up fat burning and reducing calorie intake. Proponents of the diet also claim that it can improve heart health, blood sugar control, and mood, as well as fight inflammation.

However, it's important to note that the carnivore diet is extremely restrictive and may be challenging to maintain in the long term. It also lacks many important nutrients found in plant-based foods, including fiber, vitamins, and beneficial plant compounds like antioxidants. The high consumption of animal fat and cholesterol on the carnivore diet may also have negative health effects, such as increasing the risk of heart disease and certain types of cancer.

While the carnivore diet may lead to initial weight loss, it is not a balanced or sustainable way of eating. It is always recommended to consult with a healthcare professional before starting any new diet, especially one as restrictive as the carnivore diet.

It's extremely restrictive and likely unhealthy in the long term

The carnivore diet is extremely restrictive and likely unhealthy in the long term. The diet consists of only meat and animal products, excluding all other foods. This means it is very low in vitamin C, folate, and fibre, and is difficult to maintain.

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. However, no research backs its purported benefits. There are no controlled studies that support the claims that the carnivore diet can treat depression, anxiety, arthritis, obesity, diabetes, and more.

The highly restrictive nature of the diet makes it difficult to follow long-term. It is also likely to be unsustainable and too boring, with food cravings eventually kicking in.

The carnivore diet is also likely to be unhealthy in the long term. It is high in fat, cholesterol, and sodium, which can lead to an increased risk of heart disease, kidney disease, and other negative health outcomes. The diet also lacks certain micronutrients and beneficial plant compounds, such as antioxidants, which are associated with a lower risk of long-term conditions like heart disease, certain cancers, Alzheimer's, and type 2 diabetes.

The carnivore diet also does not provide fibre, which is important for gut health and healthy bowel movements. A lack of fibre can lead to constipation and an increased risk of colon cancer.

Overall, the carnivore diet is unnecessarily restrictive and is not a healthy long-term option. A well-rounded diet that includes a variety of healthy foods is more sustainable and will likely provide more health benefits.

It's not recommended for certain groups, including children and pregnant or lactating women

The carnivore diet is not recommended for certain groups, including children, pregnant women, and lactating women. This is because the diet is extremely restrictive and may lead to nutritional deficiencies.

The carnivore diet consists of only meat and animal products, excluding all other foods. This means that it lacks many beneficial nutrients found in plant-based foods, such as fiber, vitamins, and antioxidants. While meat provides many micronutrients, following a restrictive diet like the carnivore diet may lead to deficiencies in some nutrients and the overconsumption of others.

Pregnant and lactating women have increased nutritional needs to support both their own health and the growth of the fetus or infant. A diversified diet that includes a variety of food groups is typically recommended to meet these nutritional needs. The carnivore diet may not provide all the essential nutrients required during pregnancy and lactation, such as folic acid, calcium, vitamin D, and omega-3 fatty acids.

Additionally, the high intake of animal-based foods on the carnivore diet may increase the risk of gestational diabetes and negatively impact fetal development. Long-term health implications for both mother and child may also be a concern, as consuming a diet high in red and processed meats has been associated with an increased risk of cardiovascular disease and certain chronic diseases.

Children may also be at risk of nutritional deficiencies if they follow the carnivore diet, as their growing bodies have unique nutritional needs that may not be met by this restrictive diet.

Overall, the carnivore diet is not recommended for children, pregnant women, or lactating women due to the potential risk of nutritional deficiencies and the lack of essential nutrients required for growth and development. It is important to consult with a healthcare professional before making any significant dietary changes, especially during pregnancy and lactation.

It may lead to 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 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 chronic diseases. However, there is no scientific evidence to support this claim.

The carnivore diet may lead to nutritional deficiencies as it eliminates highly nutritious foods like fruits, vegetables, legumes, and whole grains, which contain beneficial vitamins and minerals. While meat is nutritious, it should not be the only part of one's diet. Restrictive diets like the carnivore diet may lead to deficiencies in some nutrients and the overconsumption of others.

• Vitamin A: Vitamin A is important for the function of the eyes, heart, lungs, kidneys, and other organs. The carnivore diet may increase the risk of vitamin A deficiency unless one consumes liver or other organ meats.
• Biotin and Folate: Biotin (vitamin B7) and folate (vitamin B9) are essential for energy metabolism, DNA protection, and cell division. Deficiencies in these vitamins can lead to hair loss, rashes, neurological disorders, and a type of anemia. Organ meats, especially liver, are good sources of biotin and folate.
• Vitamin C: Vitamin C is essential for the human body, and it is difficult to obtain sufficient amounts from a carnivore diet. Meat must be of high quality, grass-fed, fresh, and either raw or lightly cooked to maximize vitamin C content. However, consuming raw meat has its own health risks.
• Vitamin E: Vitamin E is a fat-soluble antioxidant that protects tissues while fat is burned for energy. It is difficult to obtain sufficient amounts from meat alone. Good sources include fish eggs, salmon, and grass-fed beef.
• Vitamin K: Vitamin K is essential for blood clotting and bone metabolism. Deficiency may cause bleeding and osteoporosis. While pork and chicken contain relatively high levels of vitamin K2, it is still difficult to obtain enough from a carnivore diet.
• Calcium: Calcium is vital for bone formation, blood pressure regulation, muscle contraction, nerve function, and hormone signaling. Dairy is the most prevalent source of calcium in the Western diet. Strict adherents to the carnivore diet may become deficient unless they consume dairy or supplement with calcium.
• Potassium: Potassium regulates fluid balance in cells and blood pressure. Meats are generally low in potassium compared to plant foods. Mollusks and salmon are decent sources but are still lower than plant sources.
• Copper: Copper supports oxygen and energy production in the body. Beef liver is an excellent source of copper, but muscle meats alone may not provide enough unless one also consumes liver.
• Magnesium: Magnesium is essential for energy metabolism, mood, protein building, bone development, and DNA production. It is challenging to obtain sufficient amounts from meat alone. Good sources include fish eggs, mollusks, cod, and salmon.
• Manganese: Manganese is important for metabolism and bone formation. The best meat sources are shellfish, beef tripe, bass, and trout. Most other meats are low in manganese.

In addition to these specific deficiencies, the carnivore diet also lacks beneficial plant compounds like antioxidants, which have been linked to a reduced risk of certain long-term conditions like heart disease, certain cancers, Alzheimer's, and type 2 diabetes.
