The carnivore diet is a restrictive eating plan that involves consuming only meat and other animal products. It's a zero-carb approach, similar to the ketogenic (keto) and Atkins diets, but more extreme. Proponents claim it can lead to weight loss, reduced inflammation, improved blood sugar control, and enhanced mental health. However, it also raises questions about nutrient deficiencies and long-term sustainability. This article explores the carnivore diet, addresses the question of whether fruit can be included, and examines the potential benefits and risks.
What is the Carnivore Diet?
The carnivore diet centers around consuming only animal-based foods, such as meat, poultry, fish, eggs, and limited dairy. It excludes all plant-based foods, including fruits, vegetables, grains, legumes, nuts, and seeds. The diet is based on the idea that human ancestors primarily consumed meat and fish and that high-carb diets are responsible for many modern chronic diseases.
Historical Context
The concept of a carb-free diet isn't new. In the late 1700s, Scottish military surgeon Dr. John Rollo used a meat-only diet to treat diabetes patients, successfully lowering their blood sugar levels. More recently, former orthopedic surgeon Dr. Shawn Baker popularized the carnivore diet with his book "The Carnivore Diet." While Baker's medical license was temporarily revoked due to competency concerns, the diet gained further exposure through endorsements, including from comedian and podcast host Joe Rogan.
Foods Allowed
The carnivore diet restricts food choices to animal products. Acceptable foods include:
- Red meat: Steak, burgers, chuck roast
- Poultry: Chicken, lamb, pork
- Seafood: Fish like salmon and trout, seafood like oysters and clams
- Organ meats: Liver and oxtail
- Eggs: In small amounts
- Fats: Butter, fat tallow, or ghee for cooking
- Seasonings: Salt, pepper, and spices
Foods to Avoid
Any food not derived from animals is excluded. This includes:

Dairy is typically limited due to its lactose content, but some allow cheese, milk, and yogurt in moderation.
The Question of Fruit on the Carnivore Diet
Strictly speaking, the carnivore diet prohibits all plant-based products, so fruits are not allowed. The traditional carnivore diet primarily focuses on animal-based foods and excludes plant-based foods, including fruits. The Carnivore Diet and fruits do not go together because the Carnivore Diet doesn’t allow any plant-based foods. Also, fruits contain compounds that can negatively affect our health despite what many think. Of course, fruits contain nutrients as well, but you can get the same necessary vitamins and minerals from the animal-based sources introduced in this article.
Why Fruit is Typically Excluded
Fruits contain fructose, a natural sweetener that can disrupt metabolism and interfere with hunger signals. Fructose can cause various problems in our body, including disrupting metabolism and biochemistry, which can lead to metabolic disease in the long term. According to many healthcare professionals, including Dr. Anthony Chaffee, MD., these disruptions in metabolism can interfere with our hunger signals by blocking leptin and increasing ghrelin levels, which makes us feel more hungry than we really are and put our bodies into a fat-storing state instead of fat-burning.
Carbohydrates can cause metabolic syndromes and metabolic disease, leading to heart problems, inflammation, and digestive issues. Additionally, plants and fruits contain toxic compounds that can be harmful if consumed in excess, potentially affecting the immune system, kidneys, and reproductive system, and even increasing cancer risk.
Arguments for Including Fruit
While the strictest interpretation of the carnivore diet might exclude fruit, others may find a place for fruit in their diet plan without experiencing adverse effects. In looking at the carnivore diet pros and cons with fruit, which outweighs the other? While the strictest interpretation of the carnivore diet might exclude fruit, others may find a place for fruit in their diet plan without experiencing adverse effects. If you're considering adding fruit to your carnivore diet, it's recommended to do so mindfully, starting with small amounts and noting any changes or reactions.

Fruits offer vitamins and minerals, and their flavor and texture can make meals more enjoyable. The "Meat and Fruit Diet" is a variation of the carnivore diet that includes animal-based foods and fruits.
Lower-Sugar Fruit Options
If you've decided to incorporate some fruits into your carnivore diet, it's vital to choose fruits with the lowest sugar content. The best fruits to add would be those that provide nutritional benefits but don't drastically increase your carbohydrate intake. You may no longer be able to enjoy some of your favorite foods as you make this lifestyle change.
Some fruits that are lower in sugar and may be considered in moderation include:
- Berries: Strawberries, raspberries, blackberries, and blueberries
- Avocado: Technically a fruit, low in carbs and high in healthy fats
- Olives: Low in carbs
- Lemons and limes: Mostly used for flavoring and have minimal impact on carb intake when used sparingly
Fruits to avoid due to high sugar content include apples, bananas, grapes, mangoes, oranges, and pineapples.
Tips for Incorporating Fruit
If you choose to add fruit to your carnivore diet, consider these tips:

- Limited consumption: Gradually minimize your consumption and eat small portions of low-fructose fruits.
- Occasional treats: Decrease your fruit consumption and eat fruits once or twice a week as an occasional treat.
- Pre-workout fuel: Some individuals may find that consuming a small amount of fruit before a workout provides a quick energy source. Use bananas or oranges, which contain natural sugars and can be easily digested.
- Pairing with animal products: Combine fruits with animal-based foods to balance out the meal.
- Monitor your body: Pay attention to how you feel - your energy levels, your digestion, any changes in your skin or weight. Remember, dietary changes take time to show results. Be patient with yourself and the process.
Potential Benefits of the Carnivore Diet
Some individuals report positive outcomes from following the carnivore diet, including:
- Weight loss: High-protein and low-carb diets can promote weight loss due to increased satiety and metabolic rate.
- Improved blood sugar control: Limiting refined carbs and sugary foods can help manage blood sugar levels, particularly for people with diabetes.
- Reduced inflammation: By eliminating inflammatory foods like processed foods, the diet may reduce inflammation.
- Increased energy: Some people report feeling more energetic.
- Better sleep: Some people experience better sleep.
- Improved memory and focus: Some people experience improved memory and focus.
- More strength and endurance: Some people experience more strength and endurance.
However, it's important to note that these claims are largely based on anecdotal evidence and lack rigorous scientific backing.
Potential Risks and Downsides of the Carnivore Diet
The carnivore diet also carries potential risks and drawbacks:
- Nutrient deficiencies: Excluding fruits, vegetables, and other plant-based foods can lead to deficiencies in essential vitamins, minerals, fiber, and beneficial plant compounds.
- High fat, cholesterol, and sodium: The diet can be high in saturated fat and cholesterol, potentially raising LDL (bad) cholesterol levels and increasing the risk of heart disease. Processed meats can also contribute to high sodium intake, leading to high blood pressure and kidney problems.
- Lack of fiber: The absence of fiber can cause constipation and negatively impact gut health.
- Not suitable for certain populations: The diet is not recommended for pregnant or breastfeeding women, individuals with kidney disease, and those with a history of eating disorders.
Addressing Nutrient Deficiencies
If following the carnivore diet, it's crucial to consider strategies to mitigate potential nutrient deficiencies:
- Diversify meat sources: While sticking to animal-based products, remember to diversify your choices to ensure you're getting a range of nutrients.
- Prioritize organ meats: Organ meats like liver, heart, and kidney are rich in essential vitamins and minerals often found in fruits and vegetables.
- Consider supplementation: Taking vitamin, mineral, and fiber supplements can help fill in nutritional gaps.
- Include seafood: Seafood can be included for the omega-3 fatty acids.
