Endurance athletes are always looking for ways to improve their performance and achieve their goals. One approach that has gained popularity in recent years is the carnivore diet. This diet involves consuming only animal products, such as meat, fish, eggs, and dairy, while eliminating all plant-based foods.


A carnivore diet for endurance athletes works excellently for some athletes. Other athletes ‘ bodies prefer a higher-carb approach. If the Standard American Diet (SAD) approach isn’t working for you, give an all-meat diet a try.

I understand that a carnivore way of eating is only for some. My husband does excellent on a high-carbohydrate diet. The high-carb approach makes me feel horrible.

After enduring mouthfuls of sores from gels and sports drinks during extensive training sessions and races, I stumbled upon a miraculous solution for my health. In my quest for a more efficient fueling method, I discovered the carnivore way of eating. Not only did it alleviate my discomfort, but it also provided me with a better way to nourish my body.

Most people agree that no one way of eating is great for everyone. Everything works better on my body when I am eating an all-meat diet.

As an advocate of the carnivore diet, me and other fellow for endurance athletes claim that it can provide numerous benefits, including increased energy, improved recovery, and enhanced mental clarity.

Famous Keto and Carnivore Athletes

Some of those more notable are Ironman Champ Pete Jacobs, Ironman Age Group Course Record Holder Daniel Plews, and low carb ultra runner Zach Bitter. Although some of these athletes lean more to meat based then full carnivore, the all see the benefits of a meaty diet.

They argue that by eliminating carbohydrates and other potentially inflammatory foods, the body can operate more efficiently and effectively during long periods of physical exertion.

However, critics of the carnivore diet argue that it is too restrictive and may lead to nutrient deficiencies over time. They also point out that there is limited scientific research on the long-term effects of this diet, particularly for athletes who require high levels of energy and nutrients to perform at their best.

Despite these concerns, the carnivore diet remains an intriguing option for endurance athletes looking to optimize their performance through nutrition.

Many keto and carnivore endurance athletes use strategic carbs with key workouts and on race day.

Defining the Carnivore Diet

The carnivore diet is a type of diet that involves consuming only animal products such as meat, fish, and dairy. This means that you eliminate all plant-based foods from your diet, including fruits, vegetables, grains, and legumes. This diet is also known as a zero-carb or all-meat diet.

Core Principles

The core principles of the carnivore diet are simple: eat only animal products, and avoid all plant-based foods. This means that you need to focus on consuming high-quality meats, fish, and dairy products that are rich in nutrients.

You should also avoid processed foods, as they often contain additives and preservatives that can be harmful to your health.

As an athlete, that doesn’t mean you have to follow this protocol exactly. There are many variations of the keto, fat-adapted, carnivore diet for endurance athletes. Listen to your own body and figure out what works best for you.

Potential Benefits

The carnivore diet has gained popularity among endurance athletes due to its potential benefits. Some of the benefits of this diet include:

  • Improved energy levels: By consuming high-quality animal products, you can provide your body with the nutrients it needs to perform at its best.
  • Increased endurance: Animal products are a great source of protein, which can help to build and repair muscle tissue. This can lead to increased endurance and improved performance.
  • Reduced inflammation: Many plant-based foods contain compounds that can cause inflammation in the body. By eliminating these foods, you can reduce inflammation and improve recovery time.

While the carnivore diet may not be suitable for everyone, it can be a great option for endurance athletes who are looking to improve their performance and overall health. If you are considering this diet, it is important to speak with a healthcare professional to ensure that it is safe for you.

Carnivore Diet and Endurance Training

If you are an endurance athlete considering the carnivore diet, you may wonder how this way of eating can affect your training, adaptation, and recovery. Here are some important points to consider:

Energy Metabolism

The carnivore diet is a high-fat, moderate-protein, and low-carbohydrate diet. This means that your body will rely more on fat for energy instead of glucose from carbohydrates.

While this may seem counterintuitive for endurance athletes who traditionally rely on carbohydrates for fuel, some studies suggest that fat adaptation can improve endurance performance and reduce the risk of bonking or hitting the wall during long events.

However, fat adaptation takes time. This is best done during the off season with a reduction in carbohydrates and an increase in fat and protein intake over several weeks or months.

During this period, you may experience some side effects such as fatigue, brain fog, and decreased performance. It is important to monitor your energy levels, hydration, and electrolyte balance to avoid any negative effects.

For optimal adaptation, it is advisable to focus on Zone 1 and Zone 2 Training. Additionally, when transitioning to a carnivorous athlete diet, it is crucial not to overlook the importance of electrolytes.

Adaptation and Performance

Adaptation to the carnivore diet may vary depending on your individual metabolism, training load, and genetics. Some athletes report improved energy, focus, and recovery on the carnivore diet, while others may struggle with low energy.

It is important to note that the carnivore diet is not a magic bullet for performance and health. It is still essential to follow basic principles of endurance training, such as progressive overload, proper rest and recovery, and individualized nutrition and hydration strategies.

Recovery and Muscle Soreness

One potential benefit of the carnivore diet for endurance athletes is its high protein content. Protein is essential for muscle repair and recovery after intense exercise. However, excessive protein intake may also adversely affect kidney function and digestion.

If you don’t have pre-existing kidney disease, you won’t have to worry much about kidney problems. As always, check with a trusted doctor if you are concerned with kidney disease.

It is recommended to consume high-quality protein sources such as grass-fed beef, wild-caught fish, and organ meats and to balance protein intake with adequate fat and micronutrient intake.

Some athletes not interested in eating the gristle may also benefit from supplementing with collagen or amino acids to support joint health and recovery.

In conclusion, the carnivore diet can be a viable option for endurance athletes who are willing to experiment and adapt to a high-fat, moderate-protein, and low-carbohydrate way of eating.

However, consulting with a qualified healthcare professional and monitoring your energy, performance, and recovery is important to ensure optimal health and performance.

Nutritional Considerations for Endurance Athletes

As an endurance athlete, you need to pay close attention to your nutritional intake to ensure optimal performance. While following a carnivore diet, it is important to consider the following micronutrients and vitamins:

Micronutrients and Vitamins

  • Iron: Iron is essential for endurance athletes as it helps transport oxygen to your muscles. Red meat is a great source of heme iron, which is more easily absorbed by the body than non-heme iron found in plant-based foods.
  • Vitamin B12: This vitamin is crucial for energy production and red blood cell formation. Since vitamin B12 is only found in animal products, it is important to include them in your diet.
  • Zinc: Zinc is important for immune function, protein synthesis, and wound healing. Red meat and seafood are excellent sources of zinc.

In addition to these micronutrients, it is also important to consider hydration and electrolytes:

Hydration and Electrolytes

  • Water: Staying hydrated is crucial for endurance athletes. Make sure to drink enough water throughout the day and during workouts to avoid dehydration.
  • Sodium: Sodium is an important electrolyte that helps regulate fluid balance in the body. Including salt in your diet can help replenish sodium lost through sweat during exercise.
  • Potassium: Potassium is another electrolyte that plays a role in fluid balance and muscle function. Meat and fish are good sources of potassium.

Lastly, it is important to consider the quality and quantity of fatty acids and proteins in your diet:

Fatty Acids and Proteins

  • Omega-3 fatty acids: These fatty acids have anti-inflammatory properties and may improve endurance performance. Fatty fish such as salmon and sardines are excellent sources of omega-3s.
  • Protein: Adequate protein intake is important for muscle repair and growth. While following a carnivore diet, make sure to include a variety of animal products such as beef, poultry, fish, and eggs to ensure you are getting all essential amino acids.

By paying attention to these nutritional considerations, you can ensure that your carnivore diet supports your endurance performance.

Implementing the Carnivore Diet

If you’re an endurance athlete looking to try the carnivore diet, you should keep a few things in mind to ensure a smooth transition. Here are some tips for implementing the carnivore diet:

Transitioning to Carnivore

Transitioning to a carnivore diet can be challenging, especially if you’re used to a high-carbohydrate diet. It’s essential to take it slow. This is best done during the off-season. The process can take weeks if you are young and healthy or months if you have insulin resistance.

During the transition phase, it’s important to listen to your body and adjust your food intake accordingly. You may experience some fatigue and reduced performance initially, but this should improve as your body adapts to the new diet.

Meal Planning and Preparation

Meal planning and preparation are key to success on the carnivore diet. It’s important to choose high-quality, nutrient-dense animal products and vary your protein sources to ensure you’re getting all the essential amino acids.

My go-to place for quality meat is Arizona Grass Raised Beef.

Meal prep can also help you stay on track with your diet and avoid temptation. Consider cooking in bulk and freezing meals for later use. You can also use a slow cooker or pressure cooker to save time and simplify meal prep.

Supplementation Strategies

While a well-planned carnivore diet can provide all the nutrients your body needs, some athletes may benefit from supplementation. For example, vitamin D and omega-3 fatty acids are essential for optimal health and performance and may be challenging to obtain from food alone if you are not consuming fatty fish, egg yokes, or live in an area that doesn’t have direct sunlight.

If you’re considering supplementation, it’s important to choose high-quality products and consult with a healthcare professional to determine your individual needs.

Sports fuels compatible with a keto and carnivore diet

Some keto and carnivore athletes use strategic carbs to bost their performance for key workouts and on race day.

My go-to fuels are SFuels for training and racing. Vespa Power for an amino acid performance boost. Many keto and fat-adapted athletes also use UCAN.
