Is The Carnivore Diet Sustainable In The Long Term?

The Carnivore Diet: A Brief Overview

The Carnivore Diet has gained popularity in recent years as an extreme form of low-carb, high-fat eating. As the name suggests, this diet primarily consists of animal products, including meat, fish, eggs, and dairy. It completely eliminates all plant-based foods, such as fruits, vegetables, grains, and legumes. While the Carnivore Diet has its proponents who claim various health benefits, it is essential to examine its basic principles and potential drawbacks before deciding if this dietary approach is right for you.

What is the Carnivore Diet?

The Carnivore Diet, also known as a zero-carb or all-meat diet, is a dietary approach that emphasizes the consumption of animal products while excluding all plant-based foods. It promotes the idea that our ancestors thrived on a diet primarily consisting of animal protein and fat, and that many modern health issues are the result of consuming carbohydrates and plant toxins. Advocates of the Carnivore Diet believe that eliminating plant-based foods can lead to weight loss, improved mental clarity, reduced inflammation, and better overall health.

The basic principles of the Carnivore Diet

The Carnivore Diet is relatively straightforward in terms of its principles. The primary objective is to consume animal products, including meat, fish, eggs, and dairy, while eliminating all plant-based foods. This means avoiding fruits, vegetables, grains, legumes, and even certain processed foods that may contain plant ingredients. Followers of the Carnivore Diet often prioritize high-quality animal products, such as grass-fed beef and free-range eggs, to ensure they receive maximum nutrition from their chosen sources.

Popular proponents of the Carnivore Diet

The Carnivore Diet has gained attention through several influential figures who promote its benefits. Dr. Shawn Baker, an orthopedic surgeon and athlete, is one of the most well-known proponents of this dietary approach. He advocates for a meat-heavy diet and claims it has improved his physical performance and overall health. Other proponents include Jordan Peterson, a psychologist, and his daughter, Mikhaila Peterson, who credit the Carnivore Diet with helping them manage various health conditions. Their stories, combined with the allure of simplifying dietary choices, have contributed to the growing popularity of the Carnivore Diet.

The Question of Long-Term Sustainability

While the Carnivore Diet may have its proponents and short-term benefits, there are valid concerns about its long-term sustainability. It is crucial to consider the potential drawbacks before deciding to adopt this dietary approach.

Defining long-term sustainability

Long-term sustainability refers to the ability to adhere to a particular diet for an extended period without negatively impacting one’s health or overall well-being. In the case of the Carnivore Diet, sustainability involves whether it can provide all the necessary nutrients, support optimal health, and be followed consistently over time.

The potential drawbacks of the Carnivore Diet

One of the main concerns surrounding the Carnivore Diet is its exclusion of essential nutrients found in plant-based foods. Fruits and vegetables, for example, provide important vitamins, minerals, dietary fiber, and antioxidants that contribute to overall health and reduce the risk of chronic diseases. By eliminating these foods, followers of the Carnivore Diet may be at a greater risk of nutrient deficiencies, which can have significant long-term consequences.

Exclusion of essential nutrients

By solely relying on animal products, the Carnivore Diet inherently omits vital nutrients commonly found in plant-based foods. Nutrients such as vitamin C, fiber, and phytochemicals are typically abundant in fruits and vegetables but absent or minimal in animal products. While it is possible to obtain some of these nutrients through organ meats or specific types of seafood, it becomes more challenging to ensure adequate intake without variety in the diet.

Risks of nutrient deficiencies

Without a diverse range of plant-based foods, the Carnivore Diet may pose risks of nutrient deficiencies over time. For example, the lack of dietary fiber can negatively impact gut health and increase the risk of constipation and other digestive issues. A deficiency in vitamin C may lead to scurvy, a potentially severe condition. It is, therefore, essential for individuals on the Carnivore Diet to consider supplementation or carefully select nutrient-dense animal products to mitigate the risk of deficiencies.

Impact on gut health

The exclusion of plant-based foods in the Carnivore Diet can have a significant impact on gut health. The diverse range of fiber and prebiotics found in fruits, vegetables, and whole grains plays a crucial role in nourishing the beneficial bacteria in the gut. Without these substrates, the gut microbiome may become imbalanced, potentially leading to digestive disturbances and compromised overall health.

Lack of dietary variety and potential boredom

Another potential drawback of the Carnivore Diet is the lack of dietary variety, which could lead to monotony and lack of enjoyment in meal choices. Many individuals find pleasure in the sensory experience of consuming a wide range of flavors, textures, and colors from various food sources. The restrictive nature of the Carnivore Diet may make it difficult to sustain long-term due to a potential lack of gustatory satisfaction.

The environmental factor: Ethical and sustainability concerns

From an ethical and environmental standpoint, the Carnivore Diet raises significant concerns. The intensive farming practices required to produce large quantities of animal products can have detrimental effects on the environment, including deforestation, greenhouse gas emissions, and water pollution. Additionally, the ethical considerations of animal welfare and the sustainability of relying heavily on animal products are essential factors to consider when evaluating the long-term viability of the Carnivore Diet.

Dealing with social situations and eating out

Following the Carnivore Diet may present challenges when it comes to social situations and eating out. Many social gatherings and restaurants offer limited options for individuals following such a restrictive diet. This can make it challenging to participate fully in social activities or enjoy a meal outside of the home. The potential isolation and difficulty in maintaining social connections may negatively impact the sustainability of the Carnivore Diet in the long term.

Limited long-term research

While some individuals have reported success with the Carnivore Diet in the short term, there is a lack of long-term research on its effects and sustainability. The limited evidence available makes it challenging to fully assess the potential risks and benefits of following this dietary approach over an extended period. Without substantial research on the long-term impact of the Carnivore Diet on human health, it is difficult to make a well-informed decision regarding its suitability for sustained use.

Success stories and anecdotal evidence

Despite the lack of long-term research, there are success stories and anecdotal evidence from individuals who have thrived on the Carnivore Diet. Some report weight loss, improved digestion, reduced inflammation, increased energy, and enhanced mental clarity. However, it is important to note that individual experiences can vary significantly, and what works for one person may not work for another. Anecdotal evidence should be viewed with caution and not solely relied upon when considering the long-term sustainability of the Carnivore Diet.

Alternative Approaches and Modifications

Considering the potential drawbacks of the Carnivore Diet, it may be beneficial to explore alternative approaches or modifications that could improve long-term sustainability and nutrient intake.

The carnivore-ish approach: Incorporating some non-animal foods

For individuals who find the Carnivore Diet too restrictive or perceive a need for plant-based foods, a “carnivore-ish” approach may be more suitable. This modified version allows the inclusion of small amounts of non-animal foods, such as low-carb vegetables or berries, while still predominantly relying on animal products. This approach provides an opportunity to incorporate additional nutrients and dietary variety while maintaining the core principles of the Carnivore Diet.

Cyclical carnivore diet: Time-restricted periods of carnivore eating

Another alternative is the cyclical carnivore diet, which involves alternating periods of strict carnivore eating with periods that include a wider variety of foods. For example, an individual may follow the Carnivore Diet for a designated period, such as one week, and then incorporate plant-based foods for the following week. This approach allows for dietary flexibility and potentially mitigates some of the concerns surrounding long-term sustainability and nutrient deficiencies.

Modified versions: Implementing small changes for better nutrient intake

Individuals interested in the Carnivore Diet can also consider implementing small changes to improve nutrient intake. For instance, incorporating organ meats or nutrient-dense seafood, such as wild-caught fatty fish, can provide additional vitamins, minerals, and essential fatty acids. Additionally, experimenting with different cooking methods and seasonings can help enhance the sensory appeal and overall enjoyment of meals, making the diet more sustainable in the long term.

Consulting with a healthcare professional or dietitian

Before embarking on the Carnivore Diet or any significant dietary change, it is crucial to consult with a healthcare professional or registered dietitian. They can provide personalized guidance, evaluate individual nutrient needs, and monitor any potential health risks. Professional guidance is especially important when considering a diet as restrictive as the Carnivore Diet to ensure optimal health and minimize the risk of long-term nutrient deficiencies.

The Importance of Individualization

When considering the Carnivore Diet or any dietary approach, it is essential to prioritize individualization and consider personal health goals and bio-individuality.

Considering bio-individuality and personal health goals

Bio-individuality recognizes that each person has unique nutritional needs and preferences based on factors such as genetics, lifestyle, activity level, and existing health conditions. Understanding one’s individual requirements and health goals is vital when determining the appropriateness and sustainability of the Carnivore Diet. Some individuals may benefit from certain aspects of the diet while others may require a more varied approach to meet their specific needs.

Monitoring and assessing individual response

It is essential to monitor and assess individual responses when following the Carnivore Diet or any dietary change. Regularly checking biomarkers, such as blood lipids, fasting blood sugar levels, and inflammation markers, can provide valuable insights into the impact of the diet on overall health. Observing changes in energy levels, digestion, mental clarity, and weight can also help gauge the diet’s effectiveness and inform any necessary adjustments to meet individual needs.

Seeking professional guidance

Navigating dietary choices can be challenging, especially with an extreme diet such as the Carnivore Diet. Seeking professional guidance from a healthcare professional or registered dietitian is crucial to ensure the diet is meeting individual nutrient needs and supporting long-term health. They can provide tailored advice, help address any concerns or challenges, and offer support throughout the process of adopting and managing the Carnivore Diet.

Is The Carnivore Diet Sustainable In The Long Term?


When considering the Carnivore Diet as a long-term dietary approach, it is important to weigh the pros and cons carefully. While some individuals have reported benefits in the short term, the potential drawbacks, including nutrient deficiencies, impact on gut health, lack of dietary variety, and ethical/environmental concerns, must be taken into account. Alternative approaches and modifications, such as the carnivore-ish approach or cyclical carnivore diet, may offer more sustainable options. Individualization, monitoring, and seeking professional guidance are crucial for optimizing the diet’s long-term viability while balancing dietary preferences and nutritional needs. Ultimately, the decision to adopt and adhere to the Carnivore Diet should be made with careful consideration of one’s individual circumstances, goals, and overall well-being.
