The carnivore diet is a highly restrictive diet that consists of eating only animal products and a few other items. 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. While some people have reported benefits such as clearer skin, fewer migraines, weight loss, and improved management of type 2 diabetes, there are many potential side effects and drawbacks. These include an increased risk of heart disease, constipation or diarrhea, fatigue, low mood, poor gut health, skin issues, gastrointestinal discomfort, nutrient deficiencies, muscle and leg cramps, and heart palpitations.

What You'll Learn
Lack of fibre and essential nutrients
The carnivore diet is a restrictive eating plan that consists of only animal products and a few other items. It is based on the belief that the human body can thrive, or even perform better, on animal-derived nutrients alone. However, this diet lacks many beneficial nutrients found in plant-based foods, including fiber and essential vitamins and minerals.
Fiber is a non-digestible carbohydrate that promotes gut health and healthy bowel movements. It is only found in plant foods, so the carnivore diet contains no fiber. While some proponents of the carnivore diet argue that the human digestive system can adapt to a low-fiber diet, a lack of fiber can lead to constipation, a common issue among individuals on the carnivore diet. While constipation may be due to inadequate hydration or fat intake, it is important to note that fiber provides numerous benefits to overall health, including lowering cholesterol, stabilizing blood sugar, and promoting weight loss. Additionally, a diet high in fiber has been linked to a reduced risk of colon cancer.
The carnivore diet is also deficient in several essential vitamins and minerals, including vitamin C and calcium. Vitamin C is difficult to obtain in sufficient amounts on a carnivore diet, even with the inclusion of liver and other organ meats. A lack of vitamin C can lead to symptoms such as irritability, anorexia, tooth loss, poor wound healing, and brittle bones. Calcium is another nutrient that is challenging to obtain on a carnivore diet, as it is primarily found in dairy and plant-based foods. Calcium is essential for bone health, muscle contraction, and nerve health, and strict adherents to the carnivore diet may become deficient.
In addition to these specific nutrient deficiencies, the carnivore diet has been criticized for its overall lack of plant-based nutrients. Plant-based foods are rich in vitamins, fiber, and minerals, as well as beneficial plant compounds and antioxidants. Diets high in 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. The carnivore diet does not contain these plant compounds and has not been associated with any long-term health benefits.

High saturated fat and cholesterol
The carnivore diet is a highly restrictive diet that consists solely of animal products. It is claimed to aid an array of health issues, including obesity, diabetes, and heart health. However, there is very little research on the health effects of this diet, and it may have several negative side effects related to its high saturated fat and cholesterol content.
The carnivore diet is high in saturated fats due to the large amount of animal proteins and fats it includes. High consumption of saturated fat may raise your LDL (bad) cholesterol, which can increase your risk of heart disease and stroke. While recent studies have shown that the link between saturated fat intake and heart disease may not be as strong as previously believed, the high levels of saturated fat in the carnivore diet are still a cause for concern. In addition, the diet's restriction of fruits and vegetables means it may also leave you short on important vitamins and minerals, such as fiber, potassium, vitamins A and C, and folate.
The carnivore diet's restriction of carbohydrates can lead to a decrease in blood sugar levels and a reduced need for diabetes medications. However, carbohydrates are the brain's primary fuel source, and low blood sugar levels can cause a lack of energy and even nausea. The diet's high fat and protein content can also cause gastrointestinal issues, such as diarrhea, as they change the balance of good and bad bacteria in the gut.
The carnivore diet may also lead to mineral and electrolyte imbalances, resulting in muscle and leg cramps. In addition, the transition to a high-fat, low-carb diet can cause heart palpitations, flutters, or an increased stroke volume, especially if it results in low sodium, magnesium, and potassium levels. While these side effects are temporary, they can be alleviated by drinking plenty of water, increasing salt intake, and supplementing with magnesium and potassium if needed.
Overall, while the carnivore diet may offer some benefits, its high saturated fat and cholesterol content, as well as its restrictive nature, may lead to several negative side effects. It is important to consult a healthcare professional before starting any new diet, especially one as restrictive as the carnivore diet.

Unlikely to be sustainable
The carnivore diet is highly restrictive, eliminating entire food groups and leaving people short on important vitamins and minerals. For example, the diet cuts out fruits and vegetables, which are sources of fiber, potassium, vitamins A and C, and folate. This lack of dietary fiber can cause constipation and other digestive issues, and over time, insufficient fiber intake can increase the risk of colon cancer.
The diet is also high in saturated fats and cholesterol, which may increase the risk of heart disease and other health conditions. While recent studies have suggested that the link between saturated fat intake and heart disease may not be as strong as previously thought, the effects of consuming high levels of fat and cholesterol on an exclusive animal-based diet are still unknown.
The carnivore diet is also unlikely to be sustainable because it is difficult to adhere to over the long term. It cuts out many foods and beverages that people typically enjoy and that are implicated in weight gain, such as ultra-processed foods and added sugars. While this may promote short-term weight loss, it is likely that the weight will come back once a person returns to their former way of eating.
Furthermore, the carnivore diet is not well-studied, and there is a lack of long-term research and controlled studies to support the health claims made by its proponents. While some people may find benefits in the short term, there is insufficient evidence to determine the effectiveness and safety of the diet over the long term.
In summary, the carnivore diet's highly restrictive nature, potential nutritional deficiencies, high saturated fat and cholesterol content, lack of long-term research, and difficulty in sustaining weight loss all contribute to its unlikely sustainability as a long-term dietary choice.

May cause constipation and other digestive issues
The carnivore diet is a restrictive eating plan that involves the consumption of only animal products and a few other items. It is based on the controversial belief that human ancestral populations ate mostly meat and fish, and that high-carb diets are responsible for today's prevalence of chronic diseases.
One potential drawback of the carnivore diet is its lack of dietary fiber, which is abundant in plant-based foods like vegetables, legumes, and nuts, all of which are excluded from the carnivore diet. Fiber is essential for digestive health and regular bowel movements. The absence of fiber in the diet can lead to constipation, which is a common issue for those following the carnivore diet.
Initially, a diet devoid of fiber can reduce gas and bloating, but over time, the lack of fiber can cause constipation and other digestive issues. Fiber is a crucial component in promoting overall health, including lowering cholesterol, stabilizing blood sugar, and aiding in weight loss. It is recommended that women consume at least 25 grams of fiber per day, while men should aim for at least 38 grams. These recommended daily intakes are challenging to achieve on a carnivore diet.
While the carnivore diet may provide some benefits, such as the elimination of unhealthy, highly processed carbohydrates, it is important to consider the potential drawbacks and side effects. The lack of fiber is one such concern, and it may lead to constipation and other digestive issues for those adhering to the carnivore diet.

May increase risk of heart disease
The carnivore diet is a highly restrictive diet that consists solely of animal products. It is based on the controversial belief that human ancestral populations ate mostly meat and fish, and that high-carb diets are responsible for today's prevalence of chronic diseases.
However, the carnivore diet's exclusion of entire food groups means it may leave people short on important vitamins and minerals. For example, a lack of fibre in the diet can lead to constipation and other digestive issues. In addition, the diet is high in saturated fats and cholesterol, which may increase the risk of heart disease.
The link between saturated fat intake and heart disease is now thought to be weaker than previously believed. Nevertheless, the high levels of saturated fat in the carnivore diet may still be a cause for concern. The diet's restriction of carbohydrates means that insulin levels drop, causing the kidneys to excrete more sodium. This can lead to low levels of sodium, which in turn can cause heart palpitations, flutters, or an increased stroke volume.
The carnivore diet is not recommended for people with diabetes, heart disease, or high blood pressure due to its high saturated fat and sodium content. While the diet may lead to short-term weight loss, it is likely unsustainable in the long term. There is also very little research on the health effects of the carnivore diet, and no controlled studies have analysed its effects.
