The carnivore diet has been making waves in wellness circles, with people claiming it's cured their digestive issues, autoimmune conditions, and more. But is eating only animal products actually healthy, or is this just another extreme diet trend?
As someone who's experimented with various eating approaches over the years—including an unintentional paleo phase—I've learned that the key isn't following the latest trend. It's understanding what your individual body needs and responding accordingly.
That said, there are some interesting aspects to the carnivore diet, particularly when it comes to gut health. Let me break down what this diet actually involves, what the science says, and who might (or might not) benefit from it.
What Is the Carnivore Diet?
The carnivore diet is exactly what it sounds like: you eat only animal products and eliminate all plant foods. This includes:
Allowed foods:
Red meat (beef, lamb, pork)
Poultry (chicken, turkey, duck)
Fish and seafood
Eggs
Organ meats
Bone broth
Animal fats (tallow, lard, butter)
Eliminated foods:
All vegetables and fruits
Grains and legumes
Nuts and seeds
Dairy (for some versions)
Any plant-based foods, spices, or seasonings
Think of it as an extreme version of the ketogenic diet, but instead of just being low-carb, it's zero-carb.
Potential Benefits of the Carnivore Diet
Digestive symptom relief: For people with severe inflammatory bowel disease, Crohn's disease, or ulcerative colitis, eliminating fiber and plant compounds can provide short-term symptom relief. This works on the same principle as a low-residue diet that doctors sometimes prescribe during IBD flares.
Reduced inflammation: Some people report decreased joint pain and inflammation markers on a carnivore diet. This might be due to eliminating plant compounds they're sensitive to, or simply because they're eating more anti-inflammatory nutrients from high-quality animal products.
Weight loss: The high protein and fat content can be very satiating, leading to naturally reduced calorie intake. Protein also has a higher thermic effect, meaning your body burns more calories digesting it.
Autoimmune symptom improvement: Some individuals with autoimmune conditions report symptom improvements, possibly due to eliminating plant-based triggers or increasing nutrient density from organ meats.
Serious Concerns About Long-Term Carnivore Diet Use
Nutrient deficiencies: Eliminating all plant foods removes important vitamins and minerals like vitamin C, vitamin E, vitamin K, folate, magnesium, and thousands of beneficial plant compounds (phytonutrients) that support long-term health.
Lack of fiber: Fiber feeds beneficial gut bacteria and supports digestive health. Long-term elimination could negatively impact your microbiome diversity.
Limited research: There are virtually no long-term studies on the safety or effectiveness of eating only animal products. Most of the evidence is anecdotal.
Potential health risks: This approach may not be appropriate for people with kidney disease, certain genetic predispositions, thyroid or adrenal issues, or women in their reproductive years who need adequate nutrients for hormonal health.
Sustainability concerns: Both environmentally and practically, eating only animal products long-term raises questions about sustainability and social eating situations.
Who Might Consider a Short-Term Carnivore Approach
The carnivore diet might be worth exploring as a short-term elimination protocol for people with:
Severe inflammatory bowel disease during acute flares
Multiple food sensitivities that make eating difficult
Autoimmune conditions that haven't responded to other dietary approaches
Persistent digestive issues that haven't been resolved with other methods
Even then, it should be done under medical supervision and with a plan for reintroduction and long-term sustainability.
A More Balanced Approach to Gut Health
If you're dealing with digestive issues, there are less extreme approaches that might be more sustainable:
Modified paleo approach: Focus on high-quality animal proteins while including well-tolerated vegetables, fruits, and healthy fats. This can be customized based on your individual sensitivities.
Elimination diet: Work with a practitioner to systematically identify trigger foods without eliminating entire food groups permanently.
Root cause investigation: Consider comprehensive stool testing to identify specific imbalances, infections, or deficiencies that can be addressed directly.
Anti-inflammatory diet: Focus on reducing processed foods, sugar, and known inflammatory triggers while emphasizing nutrient-dense whole foods.
The Importance of Bio-Individuality in Nutrition
What works for one person may not work for another. Some people thrive on higher-carb diets with plenty of plants, while others feel better with more animal products and fewer carbohydrates.
The key is paying attention to how different foods make you feel, not just following what's trendy or what worked for someone else.
If you're considering the carnivore diet, ask yourself:
Are you trying to address specific health issues?
Have you tried less restrictive approaches first?
Do you have support from a healthcare provider?
What's your plan for long-term sustainability?
The Bottom Line on Carnivore Diet and Gut Health
While the carnivore diet might provide short-term relief for some people with specific digestive issues, it's not a magic solution or appropriate long-term approach for most people.
If you're dealing with gut health issues, focus on identifying and addressing root causes rather than eliminating entire food groups. Work with a qualified practitioner who can help you develop a sustainable approach that supports your individual needs.
Remember: the best diet is one that you can follow long-term, provides adequate nutrition, supports your health goals, and fits into your actual life. Extreme restriction isn't sustainable for most people, and it's often not necessary to achieve your health goals.
