The carnivore diet, which involves eating only animal products and eliminating all plant foods and processed foods, is often combined with intermittent fasting. Intermittent fasting refers to meal timing, where one cycles between periods of eating and fasting. A common method is fasting for 16-20 hours and eating within a 6-8 hour window. The carnivore diet is a zero-carb, high-protein, and high-fat diet, and the benefits of intermittent fasting are similar to those of the carnivore diet, including reduced inflammation and improved metabolic health. Fasting for longer periods, such as 72 hours, can also be beneficial when combined with the carnivore diet, offering additional therapeutic effects. However, it is important to note that fasting can be challenging, and one should start with shorter fasts and gradually increase the duration.

What You'll Learn
Intermittent fasting and the carnivore diet
The carnivore diet, on the other hand, is a zero-carb, high-protein, and high-fat diet where you only eat animal products. This diet provides the body with essential nutrients and a steady energy source through high-quality proteins and fats. The nutrient-rich nature of animal foods means it is tough to overeat, and you are less likely to eat soon after.
Combining the two approaches can amplify the health benefits of both. Intermittent fasting and low-carb diets like the carnivore diet have been shown to be powerful interventions against inflammation. Research shows that when we are in a state of caloric restriction, we have faster cognition, our blood vessels become dilated, and our muscles are more resistant to lactic acid.
However, it is important to note that fasting is not easy for everyone, especially on a new diet. If you are new to the carnivore diet, it is better to get adapted to it for a few weeks and then start fasting with simpler methods. Start with a shorter fast, like 12–16 hours, and gradually try longer fasts.
Additionally, while the carnivore diet can provide a solid nutritional foundation, it is easy for picky dieters to undereat, especially if the fast has been stretched to the point where there is only space for one or two meals. It is crucial to listen to your body and ensure you are not using fasting as a compensatory mechanism for overeating or disordered eating.

Fasting for 72 hours
The carnivore diet is a powerful nutritional approach that can be life-changing for many people. When combined with intermittent fasting, it can help supercharge weight loss goals and provide other benefits. Intermittent fasting is an eating pattern that cycles between periods of eating and avoiding any caloric intake. It focuses on when you eat rather than specifying what foods you eat. Some common fasting protocols include the 16/8 method (16 hours of fasting followed by an 8-hour eating window), the 18/6 method, the 20/4 method, and the One Meal a Day (OMAD) approach.
The carnivore diet and 72-hour fasts can work synergistically to optimize health. The carnivore diet, which primarily involves consuming animal products and eliminating most other food groups, is sometimes considered a form of "fast mimicking." This is because it can lead to reduced insulin levels and induce a state of ketosis, where the body burns fat for fuel instead of carbohydrates. However, while the carnivore diet provides essential nutrients and a steady energy source, a 72-hour fast deprives the body of all food intake, which can deepen the state of ketosis and autophagy. Autophagy is a process where cells clean out any unnecessary or dysfunctional components, and it is accelerated during prolonged fasting.
Before attempting a 72-hour fast, it is important to gradually progress from shorter fasts and stay adequately hydrated. Listen to your body and stop fasting if you feel unwell or experience adverse symptoms. It is also crucial to ensure that you are not using fasting as a compensatory mechanism for overeating or disordered eating patterns.

Fat fasting
On the carnivore diet, fat fasting typically involves eating only animal-based foods, such as meat, fish, eggs, and dairy. This is in line with the diet's focus on animal products and elimination of plant-based foods.
There are several types of fat fasting methods within the carnivore diet:
- Butter Fast: Consuming only butter for 24 to 72 hours, with meals based on butter in different forms and tastes to maintain energy levels.
- Meat-only Fast: Eating only fatty cuts of meat for 24 to 72 hours.
- Bone Broth Fast: Consuming bone broth, a nutrient-dense liquid made by simmering bones and connective tissue, for a day.
Before attempting any form of fasting, it is always advisable to consult with a healthcare professional to ensure it is safe and suitable for your individual needs.

Benefits of fasting on a carnivore diet
Intermittent fasting and the carnivore diet are two popular approaches to health and wellness. The carnivore diet is a zero-carb, high-protein, and high-fat diet where only animal products are consumed. Intermittent fasting refers to meal timing, where one cycles between periods of eating and fasting.
Combining the carnivore diet with intermittent fasting has been shown to be beneficial. A Harvard University survey study on the carnivore diet found that 83% of carnivore dieters surveyed practiced some form of intermittent fasting, and the results were dramatically beneficial.
Weight Loss
The carnivore diet is a high-protein and high-fat diet, which helps to keep you satiated and reduces the urge to overeat. Intermittent fasting can also aid in weight loss by creating a caloric deficit.
Reduced Inflammation
High-carb diets promote inflammation, while low-carb diets like the carnivore diet decrease inflammation. Intermittent fasting has been shown to effectively reduce markers of inflammation, which is associated with powerful downstream benefits such as a reduction in the severity and risk of neurodegenerative diseases.
Improved Metabolic Health
Fasting, especially extended fasts, can improve metabolic health by reducing insulin levels and promoting ketosis. The carnivore diet itself mimics many benefits of fasting, and incorporating intermittent fasting can enhance these benefits.
Cellular Repair and Immune System Regeneration
Prolonged fasting accelerates autophagy, a process where cells clean out any unnecessary or dysfunctional components. Intermittent fasting can also boost immune system regeneration, promoting overall wellness.
Balanced Hormones
Intermittent fasting helps to balance hormones by structuring meal timing. This can improve energy levels and enhance overall health and well-being.
It is important to note that fasting is not easy for everyone, especially when combined with a new diet. It is recommended to start with shorter fasts and gradually increase the duration to avoid negative health effects. Additionally, it is crucial to listen to your body and ensure that fasting is not used as a compensatory mechanism for overeating or disordered eating.

Drawbacks of fasting on a carnivore diet
While the carnivore diet and intermittent fasting can be beneficial when combined, there are some drawbacks and precautions to consider. Here are the disadvantages of fasting on a carnivore diet:
Potential Disadvantages of Fasting on a Carnivore Diet:
Difficulty in Adherence: The carnivore diet is already restrictive, and adding intermittent fasting may make it even more challenging to adhere to. Restricting both food choices and eating times can be demanding and may not suit everyone's lifestyle or preferences.
Excessive Hunger and Unhealthy Behaviors: Some people may struggle with excessive hunger, especially if they have a history of caloric restriction or malnutrition. Intentionally denying food through intermittent fasting could lead some individuals back into unhealthy behaviors due to increased hunger.
Nutritional Deficiencies: The carnivore diet restricts entire food groups, and combining it with intermittent fasting may further limit nutrient intake. Prolonged fasting periods, especially for athletes or highly active individuals, could result in insufficient calorie and nutrient intake, potentially affecting overall health and performance.
Counterproductive for Certain Goals: Extended fasting periods might be counterproductive for certain goals. For example, if you're an athlete, fasting for an extended period during competition periods is generally not recommended. Additionally, if you're already eating a carnivore diet, which excludes potentially harmful or toxic foods, the benefits of extended fasting may be diminished.
Not a Quick Fix: Combining the carnivore diet with intermittent fasting is not a quick-fix solution for weight loss or health issues. Fasting should be approached with caution, especially if one is trying to address malnutrition or insulin resistance. It is essential to consult a healthcare professional before making significant dietary changes.
Individual Variations: Everyone's body is unique, and responses to diet plans can vary. While some people may thrive on the carnivore diet and intermittent fasting, others may experience challenges or negative side effects. It is important to listen to your body and make adjustments as needed.
While there may be drawbacks, many people find success and benefits in combining these approaches. It is essential to proceed with caution, listen to your body, and seek professional advice when making significant dietary changes.
