The carnivore diet is a highly restrictive diet that consists of only animal products and a few other items, such as eggs, small amounts of low-lactose dairy, and low-carb vegetables. It is promoted as a way to improve health and aid weight loss, with claims that it can help with mood issues, blood sugar regulation, and heart health. However, there is little evidence to support these claims, and the diet may lead to nutritional deficiencies and other negative side effects. Despite the potential risks and lack of research, the carnivore diet has attracted attention from those seeking to lose weight and improve medical conditions like diabetes and autoimmune issues.

What You'll Learn
Weight loss
The carnivore diet is a highly restrictive diet that eliminates most plant foods, including fruits, vegetables, grains, legumes, seeds, and nuts. It allows only the consumption of meat, poultry, eggs, seafood, fish, some dairy products, and water. This diet is popular among people who want to lose weight and improve medical conditions like type 2 diabetes.
The carnivore diet may promote weight loss by eliminating carbs and focusing on high-protein foods. Protein is the most filling macronutriente, so the diet may reduce feelings of hunger and promote weight loss, at least in the short term. In addition, the carnivore diet eliminates many foods implicated in weight gain, such as ultra-processed foods and added sugars.
Participants in a 2021 study reported substantial reductions in their body mass index (BMI) after transitioning to a carnivore diet. However, it is important to note that the study participants only followed the diet for nine to 20 months, and the long-term effects of the diet are unknown. Similar diets, like the keto diet, have also been shown to be effective for short-term weight loss.
While the carnivore diet may lead to initial weight loss, it is highly restrictive and difficult to follow long-term. It may be unsustainable for many people, and any weight lost may be regained once the diet is stopped. In addition, the diet lacks beneficial nutrients, including fiber, vitamin C, and folate, and may lead to vitamin and mineral deficiencies.
Overall, while the carnivore diet may promote short-term weight loss, it is important to consider the potential risks and sustainability of the diet before adopting it as a long-term lifestyle change. It is always recommended to consult with a healthcare professional before starting any new diet, especially one that eliminates entire food groups.

Improved health
The carnivore diet is a highly restrictive diet that promotes improved health and weight loss. The diet consists of only meat, fish, eggs, and small amounts of low-lactose dairy, and completely eliminates all plant-based foods.
The carnivore diet has been linked to several health benefits, including improved blood pressure, reduced belly fat, and improved cardiovascular health. The elimination of highly processed carbohydrates and sugary foods can help control diabetes and improve blood sugar levels. The diet's focus on high-protein and low-carb intake can promote weight loss and reduce calorie intake. Protein can also increase metabolic rate, aiding in burning more calories.
Some followers of the diet have reported improvements in their skin, fewer migraines, increased energy, better sleep, improved strength and endurance, and mental clarity. The diet is also said to improve heart health, autoimmune issues, and mood.
The carnivore diet may be beneficial for those with type 2 diabetes. By eliminating carbohydrates, the body turns fat into ketones for energy, which can speed up fat burning and weight loss. However, it is important to note that the diet can be high in saturated fat and cholesterol, and may not provide all the necessary nutrients, potentially leading to nutritional deficiencies.
While the carnivore diet may offer some health benefits, it is important to approach it with caution. There is limited research on the long-term effects of the diet, and it may not be suitable for everyone. It is always recommended to consult with a healthcare professional before starting any new diet, especially one as restrictive as the carnivore diet.

Diabetes management
Diabetes is a chronic condition where the body either doesn't produce enough insulin or cannot utilize it effectively, leading to high blood sugar levels over prolonged periods, which can cause severe health complications. While there is no cure for diabetes, treatments focus on managing blood sugar levels through medication, insulin therapy, blood sugar monitoring, and lifestyle interventions such as diet and exercise.
The carnivore diet, a highly restrictive diet consisting solely of meat, fish, eggs, and small amounts of low-lactose dairy, has gained popularity among people with diabetes as a potential tool for managing blood sugar levels. The premise of the diet is that by eliminating carbohydrates, blood sugar levels can stabilize, and the need for insulin decreases.
There are anecdotal accounts and some emerging studies indicating that the carnivore diet can help manage and even significantly reduce symptoms of Type 2 diabetes. For example, one person with Type 2 diabetes who adopted the carnivore diet reported that their blood sugar dropped from 194.4 to 86.4 mg/dL within 3 months. Another person with Type 2 diabetes reported that their blood sugar rarely exceeded 100 mg/dL and that their cholesterol ratios improved so much that even their doctors were shocked.
However, it is important to note that the carnivore diet is extremely restrictive and may be unsafe and unhealthy in the long term due to the lack of beneficial nutrients, including fiber, antioxidants, vitamins, and minerals. It is also high in saturated fat, which can increase the risk of cardiovascular disease, especially for people with diabetes. Most experts advise against the carnivore diet, especially for people with diabetes, due to the potential long-term health consequences.
While the carnivore diet may provide short-term benefits for blood sugar management in Type 2 diabetes, it is crucial to consult with a healthcare professional before making drastic dietary changes, especially if you are on medications. A well-rounded diet that includes a variety of healthy foods is generally recommended for sustainable health benefits.

Lack of variety
The carnivore diet is highly restrictive, with a lack of variety in food groups. It consists almost entirely of animal products, including meat, fish, eggs, and small amounts of low-lactose dairy. All other foods are excluded, which means cutting out several food groups, such as fruits, vegetables, beans, grains, nuts, and seeds. This lack of variety can make the diet challenging to adhere to and may contribute to its reputation as a fad or quick-fix diet.
The carnivore diet is often chosen for its perceived health benefits, with claims that it can aid weight loss, improve heart health, manage blood sugar, and enhance mood. However, the extreme restriction of food groups may lead to nutritional deficiencies. Vitamins, minerals, and fiber are typically obtained from a variety of plant-based foods, and the carnivore diet's exclusion of these foods can result in inadequate intake. For example, calcium intake may be insufficient, especially when dairy is excluded or limited.
The lack of variety in the carnivore diet can also impact the types of fats and cholesterol consumed. The diet can be high in saturated fat, which is predominantly found in animal products. While some sources suggest choosing leaner cuts of meat or including seafood for omega-3 fatty acids, the high consumption of red meat in the carnivore diet may promote inflammation. Additionally, the absence of plant-based foods means a lack of beneficial phytochemicals, which have been linked to cardiometabolic benefits.
The limited variety of food groups in the carnivore diet can also affect overall diet sustainability. The diet's restrictiveness may make it challenging to maintain long-term. While some people may find success in the short term, the lack of variety can lead to difficulties in sustaining the diet over an extended period. This challenge is common among highly restrictive diets, and a more gradual lifestyle change or a balanced diet with a variety of healthy foods is often recommended for long-term success and improved health.
In conclusion, the carnivore diet's lack of variety can lead to nutritional deficiencies, an imbalanced intake of fats, and sustainability challenges. While some individuals may experience perceived benefits, the extreme restriction of food groups may not be necessary to achieve similar outcomes, and a more varied, balanced diet is generally recommended for overall health and sustainability.

Nutritional deficiencies
The carnivore diet is a highly restrictive diet that promotes nutrient-based health improvements. It consists entirely of meat and animal products, excluding all other foods. This means it is low in vitamin C, folate, and fibre, and is difficult to maintain.
Vitamin C is essential in the human diet because our bodies cannot produce it. It is required to make some hormones and collagen. While vitamin C is easy to obtain from fruits and vegetables, it is extremely difficult to source from meat. Meat must be of high quality, grass-fed, fresh, and either raw or lightly cooked to maximise vitamin C content. However, the risks of eating raw meat are significant. To get enough vitamin C from a strict carnivore diet, one would need to eat organs like spleen, thymus, and lung. Even with liver and other organ meats included, it is still very difficult to get enough vitamin C on a carnivore diet. Most meal plans are severely deficient, and there have been multiple cases of people developing scurvy as a result of eating only meat.
Folate is another nutrient that is difficult to obtain on a carnivore diet. Folate is a B vitamin that is naturally found in many foods, especially leafy green vegetables, beans, peas, and lentils. It is also found in fruits (including oranges, strawberries, and tomatoes), as well as nuts and some meats. Folate helps the body make healthy red blood cells. It also helps prevent certain birth defects and is important for heart health. While liver and other organ meats contain some folate, it is difficult to obtain enough of this nutrient on a carnivore diet without supplementation.
Fibre is also lacking in the carnivore diet. Fibre is important for digestive health, and it helps to prevent constipation, haemorrhoids, and diverticulitis. It can also help to lower cholesterol levels and control blood sugar levels. While some people on the carnivore diet allow for a small amount of low-carb vegetables, like greens and zucchini, the diet is still generally low in fibre.
In addition to these specific deficiencies, the highly restrictive nature of the carnivore diet means that it is difficult to obtain a full range of nutrients. This diet may be particularly unsuitable for certain populations with special nutrient needs, including children and people who are pregnant or lactating.
