The carnivore diet is a restrictive diet that eliminates all plant-based foods
The carnivore diet has gained attention as an extreme and restrictive approach to nutrition. This diet eliminates all plant-based foods and focuses entirely on animal products, including meat, fish, eggs, and some dairy. By cutting out carbohydrates and plant-based foods, followers of this diet believe that they can reduce inflammation, stabilize blood sugar, and improve mental clarity. However, the exclusion of entire food groups has raised concerns among health professionals about potential long-term health risks.
The carnivore diet is considered restrictive because it excludes all plant-based foods, which are typically a significant part of a person's diet. This restriction can lead to a lack of certain nutrients and a decrease in dietary variety, which may have negative consequences for overall health. In addition, the diet's reliance on red meat, which contains compounds linked to inflammation, has prompted questions about its long-term effectiveness in reducing inflammation.
Despite these concerns, some supporters of the carnivore diet have shared anecdotal success stories and reported various health benefits. These include reduced inflammation, weight loss, improved mood, increased energy, better mental clarity, and reduced joint pain. A social media survey of 2,029 adults who followed the diet for at least six months found that 95% reported overall health improvements, and 66% to 91% experienced enhanced well-being, including better sleep, mental focus, and endurance.
While the carnivore diet may provide some benefits, it is important to consider the potential drawbacks and risks associated with such a restrictive diet. Transitioning to this diet may result in a period of low energy, hunger, and mild migraines. Additionally, there are concerns about the impact of long-term red meat consumption, and the lack of plant-based foods may affect the gut microbiome and the production of short-chain fatty acids. Furthermore, some individuals have reported issues with cortisol spikes and sleep disturbances when following the carnivore diet.

Anecdotal evidence suggests that the carnivore diet improves energy, digestion, skin, and causes weight loss
The carnivore diet eliminates plant-based foods, which can contain irritants and allergens that affect the skin. By focusing on nutrient-rich, whole animal foods, the diet provides essential vitamins and minerals that support skin repair and maintenance. Vitamin A, found in liver and other organ meats, is crucial for skin health and can help prevent acne and reduce wrinkles. Additionally, collagen and gelatin, found in bone broth, provide the building blocks for healthy skin.
The carnivore diet is also claimed to improve digestion by eliminating potentially harmful plant compounds and providing a simple, easily digestible diet. However, there is conflicting evidence regarding the impact of the carnivore diet on gut health. While some people report improved digestion, others experience diarrhea and an imbalance in gut bacteria, which can lead to gut inflammation and constipation.
In terms of weight loss, the carnivore diet may be effective due to its high protein and fat content, which can reduce hunger and increase feelings of fullness. However, this weight loss may be short-lived as the diet is highly restrictive and challenging to maintain.
While there are mixed reports of increased energy levels on the carnivore diet, some people have experienced a spike in cortisol levels, which can affect sleep and overall energy. It is important to note that individual results may vary, and more research is needed to understand the full effects of the carnivore diet on energy levels.

The diet may reduce inflammation, stabilise blood sugar, and improve mental clarity
The carnivore diet is a restrictive diet that eliminates all plant-based foods, focusing on meat, fish, eggs, and some dairy. It is a subtype of the ketogenic diet, which is known to be low in carbohydrates. The carnivore diet is considered extreme by some, and there are concerns about its long-term effects. However, advocates of the diet claim that it has many benefits, including reduced inflammation, stabilised blood sugar, and improved mental clarity.
The diet's restriction of plant-based foods and processed carbohydrates is thought to reduce inflammatory responses. Many followers of the diet have reported relief from inflammation-related conditions, such as autoimmune disorders, allergies, and skin issues. Additionally, the elimination of plant-based irritants may be beneficial for those with sensitivities to histamine buildup, a compound that contributes to immune response and can cause allergic reactions.
The carnivore diet may also help stabilise blood sugar levels. This is due to the reduction in carbohydrate intake, which limits insulin production. In a survey, individuals with diabetes saw a reduction in their HbA1c levels, indicating better blood sugar control. Furthermore, 84% to 100% of participants on diabetes medications were able to reduce or eliminate their medication.
The diet may also improve mental clarity. A social media-based survey of 2,029 adults who followed the diet for at least six months found that 66% to 91% experienced enhanced well-being, including better mental focus and improved sleep. The diet's high protein and fat content may contribute to these benefits, as these nutrients are highly satiating and can enhance weight loss.
While the carnivore diet may offer these potential benefits, it is important to note that it is a restrictive diet that may not be suitable for everyone. Some individuals may experience negative side effects during the transition phase, such as low energy, hunger, and migraines. Additionally, the diet's reliance on red meat, which contains compounds linked to inflammation, raises questions about its long-term anti-inflammatory effects. More research is needed to fully understand the potential benefits and risks of the carnivore diet.

Health professionals express concerns about the long-term effects of the carnivore diet
Health professionals have expressed concerns about the potential long-term effects of the carnivore diet, which is a highly restrictive diet that eliminates all plant-based foods and focuses solely on animal-based foods. While some proponents of the diet claim that it has a range of benefits, there is a lack of long-term research and controlled studies to support these claims.
One of the main concerns is the potential for vitamin and mineral deficiencies due to the restrictive nature of the diet. Without plant-based nutrients, it can be challenging to meet the recommended daily intake of vitamins A, C, and B12, which are essential for optimal wellness. Additionally, the carnivore diet lacks dietary fiber, which can lead to constipation and other digestive issues over time. Fiber is also crucial in reducing the risk of colon cancer, and a high-fiber diet is associated with a lower risk of long-term conditions such as Alzheimer's, heart disease, and Type 2 diabetes.
The carnivore diet is also high in saturated fats and animal proteins, which can have negative long-term effects on health. Consuming too much saturated fat can lead to an increased risk of heart disease and other health conditions. The very high protein intake associated with the carnivore diet can also lead to impaired kidney function and an increased risk of kidney stones, gout, and osteoporosis.
Furthermore, the long-term consumption of a strictly animal-based diet has been associated with significant nutritional deficiencies and negative health effects compared to a plant-based diet, including poor gut and gut microbiota health and an increased risk of cardiovascular disease. There is also the potential for transitional side effects, such as low energy, hunger, and migraines, which may deter people from sustaining the diet long-term.
While some adults consuming the carnivore diet have reported health benefits and high satisfaction, the generalizability of these findings and the long-term effects of this dietary pattern require further study. The best diet is one that can be sustained and provides a variety of healthy foods to meet an individual's nutritional needs.

Some people experience a cortisol spike and sleep issues when starting the carnivore diet
Adverse symptoms and side effects are common when starting the carnivore diet. This is known as the "Trough of Despair" or the "Trough" for short, and it is the body's natural adaptation period to carbohydrate restriction and the elimination of addictive agents and chemicals.
Some people experience a cortisol spike when starting the carnivore diet. One person reported that their smartwatch showed a resting heart rate of 100-105bpm, which is significantly higher than their normal rate of 60-70bpm. Another person reported that their smartwatch showed their heart rate variability (HRV) as unbalanced, and that their bloodwork showed their cortisol levels were high.
Cortisol is a stress hormone that regulates blood sugar and controls inflammation. During the transition to the carnivore diet, the body thinks it is starving for sugar, which causes a release of cortisol to increase blood glucose. This is a natural sympathetic stress response, also known as the "fight or flight" response.
Some people also experience sleep issues when starting the carnivore diet. One person reported losing their ability to sleep after switching from the keto diet to the carnivore diet. Another person reported that they tried the carnivore diet 12 times and each time they experienced a high heart rate and lost their ability to sleep. Studies have shown a link between low-carb diets and insomnia, and a correlation between carbohydrate consumption and sleep. A sudden shift from carbs to protein could be the reason for sleep troubles, as carb consumption increases levels of the amino acid tryptophan in the brain, which converts to serotonin, the "happiness hormone", which is needed to produce melatonin, the sleep hormone.
To reduce cortisol levels, some recommend mindful practices like meditation and forest walks, ensuring the body gets the full spectrum of nutrition, and getting enough sleep.
