Can You Actually Do A Carnivore Diet With Vegetables?

Nutrition advice can feel like navigating a maze with a blindfold on. 

One expert advises eating more plants, while another influencer recommends cutting them out entirely. 

The carnivore diet has gained serious traction lately, with advocates claiming it’s the key to rapid weight loss, reduced inflammation, and better blood sugar control.

But here’s where things get confusing: some people wonder if they can add vegetables to make the carnivore diet “healthier.” 

The short answer? Once you add vegetables, it’s no longer a carnivore diet; it becomes something entirely different.

The carnivore diet, in its most pure form, is an extreme elimination approach that removes all plant foods. While some people may see short-term carnivore diet benefits, the science tells a different story about long-term health.

Let’s examine why the strict carnivore approach may not be the best option and why combining high-quality animal proteins with vegetables and other nutritious plant-based foods can lead to a healthier, more sustainable eating pattern.

What Is A Balanced Carnivore Diet With Vegetables?

Here’s the thing: there’s no such thing as a “balanced carnivore diet with vegetables.” 

If you’re wondering:

•  What is a carnivore diet with vegetables?
• Or can you have a carnivore diet with vegetables and fruit?

These are all contradictions in terms. The carnivore diet is as close to a 0-carb diet as you can get, eliminating all plant foods.

This carnivore eating pattern is an extreme elimination diet that removes all:

• Fruits
• Grains
• Legumes
• Vegetables
• Nuts and seeds
• Most dairy products

Carnivore diet advocates claim you should eat only animal products: beef, pork, poultry, fish, eggs, and minimal dairy like butter or hard cheeses.

When it comes to weight loss, progress is made by inches, not miles, so it’s much harder to track and a lot easier to give up. The BetterMe: Health Coaching app is your personal trainer, nutritionist, and support system all in one. Start using our app to stay on track and hold yourself accountable!

The carnivore diet typically allows (1):

• Limited dairy (butter, hard cheeses)
• Poultry (chicken, turkey, duck)
• Red meat (beef, lamb, pork)
• Fish and seafood
• Eggs
• Water
• Salt

That’s it. No exceptions for “healthy” vegetables or fruits. Proponents claim that this approach mimics what our ancestors ate, eliminating all potential plant toxins and anti-nutrients.

The moment you add vegetables, you’re no longer following a carnivore diet; you’re following a low-carb, high-protein eating pattern that includes both animal and plant foods.

Why Cut Out Vegetables On A Carnivore Diet?

Carnivore diet advocates make several bold claims about why followers should eliminate all vegetables.

Let’s examine each claim and what the science actually says:

Eating Less Carbohydrates And More Protein Results In Weight Loss

Carnivore proponents argue that consuming little to no carbohydrates and more protein yields superior weight loss compared to other dietary approaches.

There’s some truth to why high-protein diets may support weight loss, but it’s not the whole story. Protein is more filling than carbohydrates or fats, which can naturally reduce your overall calorie intake (2). 

High-protein foods also have a higher thermic effect, meaning your body burns more calories digesting them (3).

However, research shows that high-protein diets and carnivore diets aren’t necessarily more effective than other well-designed dietary interventions for long-term weight loss. 

A 2011 systematic review found that while high-protein diets can be effective for weight loss, they don’t necessarily outperform other dietary interventions when the calorie intake is the same (4).

The key factor remains creating a sustainable calorie deficit, regardless of whether that comes from reducing carbs, fats, or simply eating smaller portions (5).

The Mediterranean diet, which incorporates both limited animal proteins and a variety of vegetables and other nutritious plant-based foods, has strong evidence supporting its role in promoting sustainable weight loss and overall health (6). The key isn’t eliminating entire food groups, but creating a sustainable calorie deficit with nutrient-dense foods.

Protein And Fats Don’t Raise Blood Sugar Like Carbohydrates

Carnivore advocates correctly point out that eating protein and fats doesn’t raise blood sugar levels as much as eating carbohydrates (7), which break down into glucose.

While this is technically accurate, it represents a narrow focus on blood sugar spikes rather than overall metabolic health. 

For most people without diabetes, normal blood sugar fluctuations after eating carbohydrates aren’t problematic, they’re natural and healthy (8).

Diabetes UK notes that eating fewer carbohydrates (less than 130g daily) may help lower blood sugar levels in the short term for people with type 2 diabetes (9). 

However, they don’t recommend cutting carbs completely, as they provide essential fiber, vitamins, and minerals.

Furthermore, eliminating carbohydrates can lead to other metabolic challenges, including:

• Low energy
• Impaired sleep quality
• Reduced thyroid function
• Decreased athletic performance (10)
• All factors that ultimately affect metabolic health.

More importantly, sustainable weight loss through balanced approaches will improve blood sugar management over time (11). The focus should be on overall dietary quality, not just avoiding blood sugar responses.

Avoiding Plant Foods Can Heal Autoimmune Conditions

Carnivore advocates often claim that plant compounds like lectins cause inflammation and worsen autoimmune conditions, suggesting that eliminating all plants allows the body to “heal.”

This argument oversimplifies complex nutritional science. Lectins are only problematic when legumes are consumed raw or undercooked and proper cooking neutralizes these compounds (12). The vast majority of people consume cooked beans, lentils, and grains without any issues.

The carnivore diet’s foundation (processed and red meat) actually increases inflammation. Multiple studies have linked high consumption of red meat, particularly processed varieties, to elevated inflammatory markers in the blood (13).

Additionally, the complete absence of fiber disrupts the gut microbiome. 

Beneficial gut bacteria rely on fiber to produce short-chain fatty acids, which help regulate immune function (14). This disruption can actually worsen autoimmune conditions over time.

More importantly, fruits and vegetables contain powerful antioxidants and anti-inflammatory compounds that actively reduce inflammation in the body. 

Research consistently shows that higher intake of vegetables and fruits correlates with lower inflammatory markers a (15).

Is Cutting Out Vegetables Safe?

No, eliminating vegetables from your diet is not a safe long-term health choice.

If you’re searching for answers on “Is the carnivore diet safe?”

Please note the following information:

The National Health Service’s (NHS) Eatwell Guide recommends that fruits and vegetables should make up just over a third of your daily food intake, consisting of at least 5 portions per day (16). 

This recommendation exists because vegetables serve critical functions that animal products cannot replace.

Vegetables provide the following benefits:

• Fiber for digestive health: Prevents constipation and supports beneficial gut bacteria (17).
• Vitamin C for immune function: Essential for collagen production and wound healing (18).
• Folate for cell division: Critical for DNA synthesis and red blood cell formation (19).
• Potassium for heart health: Regulates blood pressure and supports muscle function (20).
• Antioxidants for cellular protection: Combat oxidative stress and reduce inflammation (21)
• Magnesium for bone health: Supports over 300 enzymatic reactions in the body (22)
• Phytonutrients for disease prevention: Plant compounds that protect against chronic diseases (23).

Removing vegetables from your diet can lead to several serious health problems, such as the following:

• Nutrient Deficiencies

A diet without vegetables creates multiple nutritional gaps that can lead to serious health problems.

Vitamin C deficiency can develop within weeks, leading to fatigue, joint pain, and impaired wound healing. Severe deficiency causes scurvy, though this is rare in developed countries (24).

Folate deficiency affects red blood cell production and can cause anemia, characterized by fatigue, weakness, and shortness of breath (25). It can also lead to serious birth defects if women do not get enough folate during pregnancy.

Magnesium deficiency can develop over time, contributing to muscle cramps, irregular heartbeats, and an increased risk of osteoporosis (26).

• Digestive Problems

The complete absence of fiber creates immediate and long-term digestive issues (27).

Constipation becomes common as fiber is essential for regular bowel movements.

Without adequate fiber, stool becomes hard and difficult to pass (27).

Gut microbiome disruption occurs when beneficial bacteria lack their primary food source. This starving of the beneficial bacteria may lead to increased intestinal permeability, impaired immune function, and heightened inflammation (27).

• Cardiovascular Risks

The high saturated fat content of carnivore diets poses significant cardiovascular risks (28).

Elevated cholesterol levels often occur due to excessive consumption of saturated fats. 

The British Heart Foundation warns that this increases the risk of heart attack and stroke (29).

Increased blood pressure may result from high sodium intake from processed meats combined with inadequate potassium from vegetables (30, 31).

• Cancer Risk

The World Health Organization has classified processed meat as a Group 1 carcinogen, meaning there’s sufficient evidence it causes cancer in humans (32).

Colorectal cancer risk increases with higher consumption of red meat, particularly when processed varieties are consumed regularly (33).

The lack of protective compounds in vegetables removes natural cancer-fighting phytonutrients that help prevent cellular damage (23).

• Kidney and Bone Health Issues

Extremely high protein intake can strain kidney function over time (34).

Kidney stress occurs as these organs work overtime to process excessive protein waste products (34). This factor is particularly concerning for people with existing kidney problems or at risk for them.

Bone health deterioration may result from inadequate calcium intake and the acid load created by high-protein consumption without the consumption of vegetables (35).

What Happens When A Carnivore Eats Vegetables?

Adding vegetables to a meat-heavy diet yields numerous positive health benefits, as documented in the scientific literature.

• Improved Gut Health

Vegetables provide the fiber that beneficial gut bacteria need to thrive. 

A diverse, fiber-rich diet supports a healthy microbiome, which in turn influences various aspects of health, including immune function and mental well-being (27).

Research shows that individuals who consume 30 different types of plants per week have richer, more resilient microbiomes, which is a marker associated with better long-term health outcomes (36).

• Enhanced Nutrient Intake

Vegetables fill critical nutritional gaps that meat alone cannot provide. 

You’ll get essential vitamins, such as vitamin C and folate, as well as minerals like potassium and magnesium, and protective compounds like antioxidants and phytochemicals (37).

• Reduced Inflammation

Most plant-based foods are anti-inflammatory (15). 

When combined with quality animal proteins, they can help balance the potentially inflammatory effects of high meat consumption while providing protective compounds.

• Better Cardiovascular Health

Studies consistently show that people who eat at least 5 portions of fruits and vegetables daily have lower risks of heart disease and stroke (38). 

The fiber, potassium, and antioxidants in vegetables all contribute to cardiovascular protection.

• Improved Digestive Function

The fiber in vegetables promotes healthy digestion, regular bowel movements, and prevents constipation. This supports overall gut health and may reduce the risk of digestive disorders (27).

• Cancer Protection

Vegetable consumption is associated with reduced risk of several types of cancer, particularly colorectal cancer. The fiber, antioxidants, and other protective compounds work together to support cellular health (39).

Can You Do A Carnivore Diet With Vegetables?

Once you introduce vegetables, you’re no longer following a carnivore diet, you’re following a more balanced, nutrient-dense eating pattern that includes both animal and plant foods. This is actually a much healthier approach.

The NHS Eatwell Guide provides clear recommendations for incorporating vegetables into your diet (16). 

You should aim to:

• Eat at least 5 portions of various fruits and vegetables daily
• Make fruits and vegetables just over one-third of your total food intake
• Include fresh, frozen, canned, dried, or juiced varieties
• Choose a rainbow of colors to maximize nutrient diversity

The NHS defines one portion as:

• 30g of dried vegetables
• 80g of fresh, canned, or frozen vegetables
• 150ml of vegetable juice (counts as a maximum of one portion daily)

These measurements translate to practical servings like 1 medium tomato, 3 heaped tablespoons of cooked vegetables, or a handful of cherry tomatoes or baby carrots.

Here are some ways to eat more vegetables:

Start with variety: Include different colored vegetables to maximize nutrient diversity. 

Red peppers provide vitamin C, leafy greens offer folate, and orange vegetables supply beta-carotene.

Focus on preparation methods: Roasting, steaming, and grilling vegetables enhances flavor while preserving nutrients. 

Avoid deep-frying, which adds unnecessary calories and reduces nutritional value.

Balance your plate: Follow the NHS recommendation of filling half your plate with vegetables, one-quarter with lean protein (which can include quality meats), and one-quarter with whole grains or starchy vegetables.

Include different textures: Raw vegetables in salads provide crunch and maximum vitamin content, while cooked vegetables offer a variety of flavors and may be easier to digest.

If you’re looking for structured meal ideas that incorporate both quality proteins and vegetables, our high-protein, high-nutrient meal plan can help you transition to a more balanced approach compared to other plans like the, 30-day carnivore diet meal plan.

What Happens If I Eat Too Much Protein On A Carnivore Diet?

Extremely high protein intake, as seen in strict carnivore diets, can lead to several potential health concerns that are important to be aware of.

• Kidney Function Impact

Eating large amounts of protein can put additional stress on your kidneys. 

Your kidneys must work harder to process and eliminate the nitrogen waste products from protein metabolism (34). This extra demand may be particularly concerning for people with existing kidney issues or risk factors for kidney disease.

• Digestive Complications

A very high protein intake without adequate fiber can lead to digestive issues, including constipation, altered gut bacteria composition, and increased production of potentially harmful bacterial metabolites (40).

• Bone Health Concerns

Some research suggests that extremely high protein intake may increase calcium excretion, potentially affecting bone health over time (35). 

However, you may be able to avoid bone health issues when your calcium intake is adequate. Resistance exercise is also beneficial for bone health. 

• Metabolic Stress

Processing large amounts of protein requires significant energy and can create metabolic stress (41). Your body’s high-energy requirement for digestion may affect sleep quality, energy levels, and overall well-being in some people.

• Cardiovascular Implications

The combination of very high protein intake (often from red meat) with 0 fiber and high saturated fat intake may increase cardiovascular disease risk over time (29).

For those interested in a more sustainable approach that incorporates both animal proteins and plant foods, exploring a more well-rounded animal-based diet might provide a better balance of nutrients and health benefits.

Frequently Asked Questions

• Can I eat broccoli on a carnivore diet?

No, broccoli is not allowed on a strict carnivore diet. The carnivore diet eliminates all plant foods, including vegetables like broccoli. If you want to include broccoli, you’d be following a different (more balanced) eating pattern that combines animal proteins with vegetables.

• Can I eat avocado on a carnivore diet?

Avocados are not permitted on a carnivore diet because they’re a plant food. While avocados are nutrient-dense and provide healthy fats, they contain carbohydrates and fiber, which the carnivore diet excludes entirely.

• Is spinach ok on a carnivore diet?

Spinach is not allowed on a carnivore diet since it’s a leafy green vegetable. The diet strictly limits food intake to animal products only, excluding all plant-based foods including nutrient-dense options like spinach.

• Why are there no nuts on a carnivore diet?

Nuts are excluded from the carnivore diet because they’re plant-based foods that contain carbohydrates, fiber, and various plant compounds that carnivore advocates believe may cause inflammation or digestive issues. The diet only permits foods from animal sources.

The Bottom Line

The carnivore diet’s promise of simplicity comes at a significant cost to your long-term health. While short-term weight loss may occur, the elimination of vegetables creates nutritional deficiencies, digestive problems, and increased disease risk that far outweigh any temporary benefits.

Your body thrives on variety, not restriction. Quality meats can absolutely be part of a healthy eating pattern when balanced with nutrient-rich vegetables, fruits, legumes, and whole grains. This approach provides the protein your muscles need while supplying the fiber, vitamins, and protective compounds your body requires for optimal function.

Rather than following extreme elimination diets, consider working with a registered dietitian who can help you develop a sustainable eating pattern that includes foods you enjoy while meeting your health goals. Your future self will thank you for choosing balance and variety over extremes.
