What You'll Learn
The carnivore diet is a zero-carb diet
The carnivore diet is a highly restrictive diet that consists of eating only animal products, including meat, fish, and eggs, while avoiding grains, vegetables, fruits, nuts, alcohol, juices, energy drinks, and soda. This diet is based on the idea that our primal ancestors ate in a similar way, and it is claimed to provide various health benefits, such as improved mental clarity, better focus, decreased inflammation, and lower blood sugar levels.
One of the key characteristics of the carnivore diet is that it is a zero-carb diet. Carbohydrates are typically a significant source of energy for the body, but on this diet, the body enters a state of ketosis, where it burns its own fat for fuel instead of relying on glucose from carbohydrates. This can lead to increased metabolism and weight loss, which is one of the primary goals for many people following this diet.
However, it is important to note that the complete elimination of carbohydrates is not recommended for everyone. While the carnivore diet may help stabilize blood sugar levels, it can also lead to digestion problems if carbohydrates are reintroduced, causing spikes in blood sugar that result in heartburn, bloating, or nausea. Additionally, a diet devoid of carbohydrates can lead to a decrease in the intake of essential vitamins, minerals, and fiber, which are necessary for overall health and proper bodily functions.
Some people who follow the carnivore diet may choose to include small portions of vegetables or take supplements to ensure they are getting adequate nutrition. However, it is important to be mindful of the source of carbohydrates, as some supplements may contain sugars or other sweeteners that could interfere with the desired effects of the diet. Overall, while the carnivore diet may provide some benefits, it is not a sustainable or nutritionally complete diet and should be approached with caution.

Carbs are not essential for ketosis
The carnivore diet consists exclusively of animal products and is claimed to aid an array of health issues. It is a restrictive diet that focuses on meat and other animal-based foods. The diet allows the consumption of animal and meat products while avoiding grains, vegetables, fruits, and nuts. It is also recommended to avoid highly processed meats.
Carbohydrates are responsible for many essential bodily functions. They convert glucose into energy, which is necessary to support bodily functions such as walking or exercising. Carbohydrates also help store energy for later use, spare the use of proteins for energy, prevent ketosis, break down fatty acids, and perform other critical bodily functions.
The carnivore diet is naturally low in carbohydrates since meat and animal products contain almost zero carbs. While the carnivore diet does not allow carbs, this is not because they are limited but because the foods they are found in are exempt from the diet. Eating carbs while on the carnivore diet will take you out of ketosis, which can be unfavourable if you're trying to achieve the benefits of the carnivore diet, such as lowering blood sugar or weight loss.
To get into ketosis, it is recommended to consume under 50 grams of carbs per day. However, excessive protein consumption on a low-carb diet can prevent you from achieving ketosis. If you do not eat carbs, it is important to add fat to your diet to compensate, as failing to do so could lead to hunger and inadequate nutrition. A fat intake around 70% of total calories may be suitable for some people on low-carb or ketogenic diets.

The carnivore diet is not nutritionally adequate
The carnivore diet is a restrictive diet that consists of eating only meat and other animal products, such as eggs and some dairy. It is based on the controversial belief that human ancestral populations ate mostly meat and animal products and that high-carb diets are to blame for today's chronic diseases.
While the carnivore diet may lead to short-term weight loss, it is not nutritionally adequate and can lead to deficiencies in some nutrients and the overconsumption of others. The diet eliminates highly nutritious foods like fruits, vegetables, legumes, and whole grains, which contain beneficial vitamins, minerals, fiber, and plant compounds like antioxidants. These plant-based foods have been associated with a lower risk of certain long-term conditions, including heart disease, certain cancers, Alzheimer's, and type 2 diabetes.
Meat and animal products are important sources of micronutrients, but they should not be the only components of a diet. The carnivore diet is lacking in vitamin C, folate, and fiber, and it may be difficult to maintain due to food cravings and the lack of variety. Additionally, the diet may be high in saturated fat and cholesterol, which could increase the risk of heart disease.
There is a lack of scientific research and controlled studies to support the claimed benefits of the carnivore diet, such as improved mental health, decreased inflammation, and better blood sugar regulation. In fact, the diet may have the opposite effect on energy levels, as carbohydrates are important for fuelling the brain and maintaining blood sugar levels.
Overall, the carnivore diet is not nutritionally adequate and may lead to nutrient deficiencies, overconsumption of certain nutrients, and an increased risk of certain health conditions. It is not recommended by dietitians or health professionals and should be approached with caution.

The diet may cause digestion problems
The carnivore diet is a highly restrictive diet that consists exclusively of animal products, including meat and other animal-based foods. It eliminates all plant-based sources, grains, vegetables, fruits, nuts, alcohol, juices, energy drinks, and soda. While the diet is promoted for its potential benefits, including weight loss, improved mental clarity, and reduced inflammation, there are concerns about its impact on digestion due to the absence of fibre and other essential nutrients.
The carnivore diet's exclusion of plant-based foods results in a significant reduction of dietary fibre, which is essential for nourishing the trillions of microbes in our gut. These microbes thrive on diversity, and a diet rich in plant-based foods provides an array of fibres that support a diverse and healthy gut microbiome. By eliminating plant-based sources of fibre, the carnivore diet may lead to constipation and other digestive issues over time.
In addition to constipation, individuals starting the carnivore diet may experience temporary diarrhoea during the adaptation period. This is due to the elimination of plant fibre, which starves certain bacteria in the gut, leading to a microbiome reset and re-regulation. As the digestive system adjusts to the high-fat content of the carnivore diet, bile production and digestive enzymes need to increase to effectively break down and absorb fats. This transition can cause nausea and contribute to overall digestive discomfort.
The absence of fibre in the carnivore diet may also have long-term implications for gut health. Fibre is crucial for maintaining regular bowel movements and supporting the growth of beneficial gut bacteria. While the carnivore diet may initially reduce bloating and gas, the lack of fibre over time can disrupt the balance of the gut microbiome and lead to constipation and other digestive issues. Furthermore, the exclusion of plant-based foods in the carnivore diet may result in nutrient deficiencies, including vitamins and minerals such as vitamin C, magnesium, and folate.
While the carnivore diet may provide short-term benefits for some individuals, it is important to consider its potential long-term effects on digestion and overall gut health. Embracing a diverse and balanced diet that includes both animal-based and plant-based foods is generally recommended to support a healthy gut and ensure adequate nutrient intake for overall well-being.

The diet may lead to vitamin deficiencies
The carnivore diet is a restrictive way of eating that focuses on meat and other animal-based foods, completely eliminating carbohydrates. While this diet is claimed to aid an array of health issues, it may also lead to vitamin deficiencies due to the exclusion of many food groups.
A study assessed the nutrient adequacy of the carnivore diet against national nutrient reference values (NRVs) and found that while the diet met several NRV thresholds for certain nutrients, it fell short in others. Specifically, the carnivore diet was lacking in thiamin, magnesium, calcium, Vitamin C, iron, folate, iodine, and potassium. The study also found that fibre intake was significantly below the recommended level.
Vitamin C, in particular, is essential in the human diet because our bodies cannot produce it on their own. It is needed to make some hormones and collagen. While vitamin C is abundant in fruits and vegetables, it is difficult to obtain from meat. Even with liver and other organ meats included in the diet, it is still challenging to obtain sufficient vitamin C. Deficiency in vitamin C can lead to scurvy, which presents symptoms such as irritability, anorexia, tooth loss, poor wound healing, and brittle bones.
Another nutrient that may be lacking in the carnivore diet is vitamin K, which can be obtained from chicken and grass-fed beef. Adding dairy products like whole milk or cheese can further increase vitamin K intake. Boron, while not considered an essential nutrient, is also worth noting. Low boron intake has been associated with issues related to immune function, bone health, brain health, and hormone production. Boron is typically found in fruits and nuts, and strict adherents to the carnivore diet may need to consider supplementation.
In conclusion, while the carnivore diet may offer potential benefits, it is important to be aware of the risk of vitamin deficiencies. Tailored nutritional guidance and supplementation strategies may be necessary to prevent deficiencies and ensure adequate micronutrient intake.
