The carnivore diet is a highly restrictive diet consisting solely of animal products. It is claimed to aid weight loss, improve mood, and regulate blood sugar, among other health benefits. However, there is limited research investigating the health benefits of the diet. The first mainstream study on the carnivore diet was conducted by Harvard University in 2020, surveying over 2000 carnivore dieters with positive results. Participants reported high satisfaction, general health improvements, and few adverse effects. However, the diet's long-term effects on health and disease risk are unknown, and more research is needed to fully understand its impact. The carnivore diet's extreme restrictions may make it challenging to maintain, and it eliminates many foods known to improve health and provide essential nutrients, like fruits and vegetables. While it may promote short-term weight loss by eliminating ultra-processed foods and added sugars, there is little evidence to support its purported benefits, and it may lead to nutritional deficiencies.

What You'll Learn
The carnivore diet's popularity
The carnivore diet is a highly restrictive diet that consists of only animal products, including meat, fish, and other animal foods like eggs and some dairy products. It is claimed to aid weight loss, improve mood, and regulate blood sugar, among other health issues. The diet has gained popularity due to the influence of prominent social media personalities, authors, and bloggers, including Mikhaila Peterson, daughter of popular psychologist Jordan Peterson, and orthopedic surgeon Shawn Baker, whose 2019 book *The Carnivore Diet* is considered a "holy book" for the community. Podcaster Joe Rogan and popular doctors, including Dr. Kiltz and Dr. Ken Berry, also promote the diet.
The diet is among the latest and most extreme examples of low-carbohydrate fads, similar to the paleo and keto diets. It is based on the idea that some human ancestors relied heavily on animal products, that carbohydrates are not the body's preferred fuel source, and that the evidence linking meat-heavy diets to increased chronic disease is flawed. However, it is important to note that the diet is extremely restrictive and likely unhealthy in the long term. It eliminates many foods that are known to improve health and deliver essential nutrients, like fruits and vegetables, and can be high in saturated fat and cholesterol, which may increase the risk of heart disease.
While there is limited research on the carnivore diet specifically, a 2021 study by Harvard University surveyed over 2,000 carnivore dieters and found positive results, with participants reporting health benefits, high satisfaction, and few adverse effects. However, the study was based on self-reported responses, and there is no way to objectively verify the accuracy of self-reported eating habits and health outcomes. Additionally, the diet does not align with the Dietary Guidelines for Americans, which recommend that adults get 45% to 65% of their daily calories from carbohydrates.
Overall, while the carnivore diet has gained popularity due to its perceived health benefits and the influence of certain individuals, there is limited research to support its effectiveness, and it may have negative consequences for overall health due to its restrictive nature.

The lack of research
The carnivore diet is a highly restrictive diet that consists solely of animal products, including meat, fish, and other animal foods like eggs and certain dairy products. It is claimed to aid weight loss, improve mood, regulate blood sugar, and provide other health benefits. However, there is a lack of research and evidence to support these purported benefits.
The carnivore diet first gained attention in 2020 when Amber O'Hearn, who had been studying the diet for a decade, published a paper in "Current Opinion in Endocrinology, Diabetes and Obesity." Despite the diet's growing popularity, there is still limited research specifically on its effects. In 2021, a team of researchers at Harvard University conducted the first mainstream study on the carnivore diet, surveying over 2000 participants. While the results showed high satisfaction and self-reported health improvements, there has been no long-term research to support these findings.
The highly restrictive nature of the carnivore diet makes it difficult to follow long-term and can lead to nutritional deficiencies. It eliminates essential food groups, such as fruits and vegetables, which are known to provide important vitamins, minerals, and fiber. As a result, people on the carnivore diet may experience constipation or diarrhea, headaches, nausea, and a lack of energy. Additionally, the diet can be high in saturated fat and cholesterol, which may increase the risk of heart disease.
While some proponents of the carnivore diet claim that it can fight inflammation and boost energy, there is currently no evidence to support these claims. The limited research available suggests that the benefits of the carnivore diet may be short-lived and that it may be difficult to maintain in the long term. More research is needed to fully understand the effectiveness and safety of the carnivore diet, especially compared to less restrictive diets that are considered better for overall health.

Short-term health effects
Research on the carnivore diet is limited. The phrase "carnivore diet" first appeared in the title of a scientific paper in 2020, and long-term research on the topic is absent. The diet is extremely restrictive and likely unhealthy in the long term. It consists entirely of meat and animal products, excluding all other foods, and is claimed to aid weight loss, mood issues, and blood sugar regulation. However, no research backs its purported benefits.
The carnivore diet is a fad diet that is similar to other low-carbohydrate diets such as the paleo and keto diets. It is based on the idea that some human ancestors relied heavily on animal products, that carbohydrates are not the body's preferred fuel source, and that the evidence linking meat-heavy diets to increased chronic disease is flawed. The diet is popular among some social media personalities, authors, and bloggers, including Mikhaila Peterson and orthopedic surgeon Shawn Baker, who promote it as a foundation of health and wellness.
There is some limited evidence that the carnivore diet may offer a few short-term health benefits. A 2021 study found that participants with type 2 diabetes experienced reductions in their hemoglobin A1c (HbA1c) levels and significant reductions in their diabetes medication use. The same study also reported substantial reductions in body mass index (BMI) after transitioning to a carnivore diet. Additionally, participants in the 2021 study reported that the carnivore diet improved their overall health, physical and mental well-being, and some chronic medical conditions. However, it is important to note that the participants in this study only followed the diet for nine to 20 months, and the long-term effects on health are unknown. More research is needed to fully understand how this diet impacts overall health.
While the carnivore diet may offer some short-term benefits, there are also potential downsides and risks associated with it. The diet is highly restrictive and may be difficult to maintain. It eliminates foods that are known to improve health and deliver essential nutrients, like fruits and vegetables. This dietary pattern is low in carb-rich foods and high in protein, which may promote weight loss in the short term, but it is unlikely to be sustainable in the long term. The carnivore diet can also be high in saturated fat and cholesterol, which may increase the risk of heart disease. Additionally, some processed meats contain high amounts of sodium, which can lead to excessive sodium intake.

Long-term health effects
The carnivore diet is a highly restrictive diet that consists solely of animal products, including meat, fish, and other animal foods like eggs and certain dairy products. It is claimed to aid weight loss, improve mood, and regulate blood sugar, among other health issues. However, there is limited research investigating the health benefits of the diet.
In 2020, a team of researchers at Harvard University conducted the first mainstream study on the carnivore diet, which surveyed over 2000 carnivore dieters with remarkably positive results. The study found that most people on the diet experienced a high level of satisfaction with the meat-heavy meal plan, general health improvements, and few adverse effects. Additionally, the study reported that the carnivore diet may benefit people with type 2 diabetes by reducing their hemoglobin A1c (HbA1c) levels and decreasing their reliance on diabetes medications.
However, it is important to note that the 2021 study only followed participants for nine to 20 months, so the long-term health effects of the carnivore diet are still unknown. More research is needed to fully understand how this meal plan impacts overall health, including disease risk. While the diet may promote weight loss and improve chronic diseases in the short term, it is extremely restrictive, which may make it hard to maintain. It also cuts out foods that are known to improve health and deliver essential nutrients, like fruits and vegetables, which can lead to nutritional deficiencies.
The carnivore diet can also be high in saturated fat and cholesterol, which may increase the risk of heart disease. In addition, some processed meats contain high amounts of sodium, which can lead to excessive sodium intake on the carnivore diet. Overall, while the carnivore diet may offer some benefits, there is currently limited evidence that it significantly improves health, and more research is needed to investigate its effectiveness and safety.

Comparison to other diets
The carnivore diet is a highly restrictive diet that consists entirely of meat and animal products, excluding all other foods. It is claimed to aid weight loss, improve mood, and regulate blood sugar, among other health issues. However, there is limited research investigating the health benefits of the diet.
The carnivore diet is often compared to other low-carbohydrate diets like the paleo and keto diets. These diets share the idea that some human ancestors relied heavily on animal products, that carbohydrates are not the body's preferred fuel source, and that the evidence linking meat-heavy diets to increased chronic disease is flawed. However, the carnivore diet is more extreme than these diets as it eliminates all food groups except meat and animal products.
The keto diet, for example, allows for high-fat foods to replace carbohydrates, contributing to satiety and weight loss. It has been shown to be effective in decreasing weight gain and helping with certain health conditions. While the carnivore diet may also promote weight loss, it is more restrictive and may be harder to follow long-term.
The paleo diet is also less restrictive than the carnivore diet as it allows for some plant-based foods, such as fruits and vegetables. These diets also differ in that the paleo diet focuses on eating like our hunter-gatherer ancestors, while the carnivore diet is based on the idea that animal products are optimal for health.
In terms of research, the carnivore diet has even fewer studies supporting its benefits compared to the keto and paleo diets. The keto diet, for instance, has been studied more extensively and has been shown to be effective for weight loss and certain health conditions. The paleo diet, while not as well-studied as the keto diet, still has more research supporting its benefits than the carnivore diet.
Overall, the carnivore diet is a more extreme and restrictive version of other low-carbohydrate diets like the keto and paleo diets. While it may offer some benefits, such as weight loss and improved health markers for people with diabetes, there is limited research to support these claims. More research is needed to fully understand the effectiveness and safety of the carnivore diet, especially compared to other diets.
