Exploring the Carnivore Diet for Rheumatoid Arthritis
A Research-Based Overview
Rheumatoid Arthritis (RA) is an autoimmune condition marked by chronic inflammation of the joints, often accompanied by fatigue, pain, and reduced mobility. For many, traditional medications are necessary and life-saving—but others seek additional support or alternative strategies to manage their symptoms. One approach gaining traction is the carnivore diet, which emphasizes the elimination of all plant-based foods in favor of animal products exclusively. But what does the research actually say?
This article aims to provide a gentle but informative look at clinical studies, emerging science, and patient-reported outcomes related to RA and the carnivore diet. Our goal is to empower readers with knowledge, not prescriptions—encouraging thoughtful, evidence-based decisions about health and healing.
Understanding the Carnivore Diet
The carnivore diet is a restrictive dietary protocol consisting exclusively of animal-based foods—typically meats, organ meats, eggs, and animal fats. It excludes vegetables, fruits, grains, legumes, nuts, and all plant oils. Some proponents view it as an extreme form of a low-carb or ketogenic diet, emphasizing simplicity, nutrient density, and the elimination of potential dietary triggers such as oxalates, lectins, and fiber.
Clinical Research and Case Reports: What Do We Know So Far?
Clinical research specifically focused on the carnivore diet and RA is limited but growing. Below is a summary of key findings from available studies, case reports, and observational surveys:
1. Shanahan, C. (2020) – Physician Observations on Carnivore Patients
While not a peer-reviewed study, Dr. Cate Shanahan, MD, has documented multiple case observations of patients with autoimmune diseases, including RA, showing symptom remission on a carnivore diet.
Though anecdotal, her medical background lends weight to these reports, highlighting a need for further trials.

2. Peterson, S. J. et al. (2021) – Survey of Carnivore Diet Users
This study was originally published in Current Developments in Nutrition but the original link appears to be inactive.
The survey included over 2,000 carnivore diet users, 214 of whom had autoimmune conditions including RA.
Among those with autoimmune diagnoses, 89% reported improvement in symptoms; 56% reported complete remission.
While this data is now primarily cited secondhand, a summary and discussion of the study is available through this article: News-Medical.net – The Carnivore Diet: Healthy Trend or Risky Fad?
3. Lennerz, B. et al. (2021) – Medical Outcomes of the Carnivore Diet
Source: Current Developments in Nutrition, Volume 5, Issue 2, February 2021
This study assessed health status, diet adherence, and symptom changes in 2,029 people following a carnivore diet for six months or more.
Improvements included reduced inflammation, joint pain, and fatigue.
Authors called for controlled clinical trials.
4. Mikhaila Peterson’s Case (2018 – ongoing)
Mikhaila Peterson, a well-known advocate, claims to have placed her severe RA in full remission through a strict carnivore diet.
Her case has not been clinically verified, but it has attracted considerable public interest.
Her story is often cited in broader discussions of diet and autoimmune disease.

This is a very compelling and heartbreaking story.
What About the Risks?
Most clinicians agree that long-term data is lacking. Concerns include:
Nutrient deficiencies (e.g., Vitamin C, fiber, magnesium)
Gut microbiome diversity loss
Potential impacts on cardiovascular health (though contested)
Unknown effects on kidney function in predisposed individuals
However, some proponents argue that many nutrient concerns are overestimated if the diet includes organ meats and bone broths.
Closing Thoughts
While the carnivore diet shows promise for some individuals with RA, it remains an experimental approach. The available research is encouraging but far from conclusive. If you’re considering dietary changes for autoimmune conditions, it’s best to consult with a knowledgeable healthcare provider, ideally one open to both conventional and integrative therapies.
