In my 14 years of having rheumatoid arthritis, I’ve gained some incredible insights into this complicated disease. Through trial and error, I’ve learned that diet can have a powerful impact on my condition and how I feel. Managing an autoimmune condition is a full-time job and requires an entire lifestyle overhaul—from what you eat to how you move (and how much), to how you process stress and emotions, as well as contributing factors like sleep and vitamin/mineral deficiencies.
One major breakthrough for me and many others has been adopting a low-carb diet, particularly keto and carnivore, which have been shown to reduce inflammation and stabilize blood sugar. But what do the experts say? I asked medical and nutrition professionals to share examples of how a low-carb, keto, or carnivore diet has helped patients with autoimmune or chronic illnesses. Here’s what they had to say.
2 Key Benefits of a Low-Carb Diet for Autoimmune & Chronic Illness Patients
1. Keto Diet Reduces RA Symptoms
For many patients with autoimmune conditions, inflammation is the primary culprit behind debilitating symptoms. Dr. Gregory Gasic, a neuroscientist and scientific consultant, has seen how diet can profoundly impact chronic illness patients. One case that stood out to him involved a rheumatoid arthritis patient whose condition had worsened despite multiple medical interventions.
“Their medications had no positive outcome, and constant pain, fatigue, and stiffness had become their new normal,” Dr. Gasic explained.
After struggling with standard treatments, the patient and their medical team decided to experiment with a low-carb, ketogenic approach. The goal was to shift the body’s primary energy source from glucose to fat, reducing inflammatory markers in the process. The results were remarkable.
“Almost instantaneously, my patient reported a drop in joint pain, increased energy, and reduced inflammation markers within weeks,” Dr. Gasic shared. “This reinforces my belief that diet can have the biggest effect on chronic disease. This patient’s outcome demonstrates how keto or low-carb, while not ideal for everyone, proved to be beneficial.”
RA, like many autoimmune diseases, is often linked to chronic inflammation, and reducing carbohydrates—especially refined sugars and processed foods—may help break the cycle of flare-ups. Dr. Gasic’s case study serves as a testament to the profound connection between diet and autoimmune health.
However, he emphasizes that making dietary changes should always be done under medical supervision:
“Food changes are within reach, but they can alter treatment plans, which is why it’s vital to talk to your healthcare provider first.”
Autoimmune diseases often go hand in hand with metabolic issues, including insulin resistance and blood sugar fluctuations. Sarah Gibson, Director of Proactive Healthcare, has seen how stabilizing blood sugar through a ketogenic diet can help manage autoimmune symptoms.
“A patient with rheumatoid arthritis saw dramatic improvements after switching to a keto diet. Seriously, within three months, their joint pain and inflammation decreased significantly,” she recalled.
But the improvement wasn’t just from cutting carbs—it was also about prioritizing high-quality fats and proteins. According to Gibson, stabilizing blood sugar levels helps prevent the systemic inflammation that can trigger autoimmune flare-ups.
“In reality, the diet helped stabilize their blood sugar and reduce systemic inflammation, which are key drivers of autoimmune flare-ups,” she explained.
This aligns with emerging research showing that blood sugar fluctuations contribute to inflammatory responses, worsening autoimmune conditions. By reducing carbohydrate intake, many patients experience fewer inflammatory triggers, leading to better symptom control.
The Role of Nutrition in Autoimmune Disease Management
Both expert insights reinforce a growing understanding that nutrition plays an incredible role in autoimmune health. While there is no one-size-fits-all approach, evidence continues to support the idea that reducing carbohydrates, particularly refined carbs and sugars may help mitigate inflammation and improve energy levels.
For those managing chronic illness, small dietary adjustments can make an impactful difference. However, as both experts pointed out, major diet changes should be done carefully and with professional guidance.
“There is something profoundly extraordinary about how food has the capacity to reduce symptoms and improve someone’s quality of life,” Dr. Gasic noted. “Yet, nutrition doesn’t always get the respect it deserves in the medical field. But for many, it can be the missing link in chronic disease management.”
Final Thoughts
Managing an autoimmune condition like RA requires more than just medication, it demands a holistic approach that includes lifestyle, movement, stress management, and most importantly, diet. My own experience with low-carb eating has been transformative, and the insights from experts like Dr. Gasic and Sarah Gibson reaffirm the power of food as medicine.
If you’re struggling with an autoimmune disease or chronic illness, consider exploring the role of nutrition in your treatment plan. Talk to your doctor, do your research, and experiment with what works best for your body. Because sometimes, the key to better health isn’t found in a prescription: it’s found on your plate.
