In an era dominated by processed foods and fast-food options, the importance of a nutrient-rich diet for overall health and well-being cannot be overstated. Dr. Terry Wahls, a physician and clinical professor of medicine at the University of Iowa Carver College of Medicine, has extensively researched the profound connection between diet and health, particularly in the context of multiple sclerosis (MS) and other autoimmune conditions. Her personal journey with MS led her to develop the Wahls Protocol, a dietary and lifestyle program designed to support mitochondrial function, brain health, and nervous system wellness.
Dr. Terry Wahls' Personal Journey and the Genesis of the Wahls Protocol
Dr. Wahls' interest in the relationship between diet and health stemmed from her own battle with MS. Diagnosed in 2000, her condition progressed despite conventional medical treatments, including chemotherapy. By 2003, she required a tilt-recline wheelchair due to muscle weakness and debilitating fatigue. Driven by a desire to find a way to slow down her disease, Dr. Wahls immersed herself in scientific literature, focusing on the role of nutrient-rich foods in boosting brain and mitochondrial health.
Inspired by the principles of the Paleolithic (paleo) diet and functional medicine, Dr. Wahls devised a program of diet and lifestyle interventions that would later become known as the Wahls Protocol. This protocol emphasizes the consumption of green leafy vegetables, fermented vegetables like sauerkraut, colorful fruits, and meat and fish packed with protein and good fats. When combined with physical therapy, electrical muscle stimulation, and other functional medicine concepts, Dr. Wahls experienced dramatic improvements in her health. Within a year, her fatigue diminished, her strength returned, and she was able to walk and cycle again.
The Core Principles of the Wahls Protocol Diet
The Wahls Protocol diet is a modified version of the paleo diet that focuses on nutrient-rich foods and the elimination of processed foods, added sugars, gluten, and dairy. The diet emphasizes the consumption of a wide variety of vegetables, fruits, healthy fats, and high-quality protein sources.
Emphasized Foods:
- Vegetables: The Wahls Protocol diet encourages the consumption of a wide variety of vegetables, with a particular emphasis on leafy greens like kale and spinach, sulfur-rich vegetables like cabbage, onions, garlic, and mushrooms, and deeply pigmented vegetables like carrots, beets, and berries. Dr. Wahls recommends aiming for nine cups of vegetables and berries per day.
- Fruits: The diet includes a variety of colorful fruits, such as berries, which are rich in antioxidants and other beneficial nutrients.
- Healthy Fats: The Wahls Protocol emphasizes the consumption of healthy fats from sources like avocados, coconut oil, ghee (clarified butter), and animal fats from non-cow sources.
- High-Quality Protein: The diet includes grass-fed meat and wild-caught fish as primary sources of protein. Organ meats, such as liver, heart, and tongue, are also encouraged once a week due to their high nutrient density.
- Seaweed: Seaweed is a rich source of iodine and selenium, essential nutrients for brain health and detoxification.
Foods to Avoid:
- Processed Foods: The Wahls Protocol eliminates processed foods, which are often high in sugar, unhealthy fats, and artificial ingredients.
- Added Sugars: The diet restricts added sugars, as they can contribute to inflammation and negatively impact the gut microbiome.
- Gluten: Gluten, a protein found in wheat, barley, and rye, is avoided due to its potential to trigger inflammation and negatively impact brain and nerve health.
- Dairy: Dairy products are excluded from the Wahls Protocol due to their potential to raise the risk of new or progressing MS.
- Eggs: Eggs are not included in the Wahls Protocol because they are considered to promote inflammation and potentially worsen MS symptoms.
- Legumes: Legumes (beans and lentils) are also off-limits.
The Three Levels of the Wahls Protocol
The Wahls Protocol is implemented in three levels, each with increasing restrictions and specific dietary guidelines:

- Level One: This level involves eating nine cups of specific types of fruits and vegetables each day while avoiding gluten, dairy, and eggs.
- Level Two: This level is a paleo version of the diet and allows organ meats, fermented foods, and seaweeds.
- Level Three: This level is a ketogenic approach.
Scientific Evidence and Research on the Wahls Protocol
While Dr. Wahls' personal experience with the Wahls Protocol is compelling, it's essential to examine the scientific evidence supporting its efficacy. Several studies have investigated the effects of the Wahls Protocol diet on individuals with MS and other autoimmune conditions.
One small study found that people with MS who switched to a paleo/Wahls-style diet for a year experienced less fatigue. However, it's important to note that participants in this study also engaged in exercise, stretching, meditation, massage therapy, and electrical stimulation therapy, making it difficult to isolate the specific effects of the diet.
Another small study found that people with MS who followed the Wahls diet consumed the right amounts of most micronutrients and metabolites (vitamins, fatty acids, and amino acids that form proteins).
A larger study, funded in part by the National Multiple Sclerosis Society, compared the Wahls diet to another plan, the Swank diet, which some experts also recommend for people who have MS. People in the study reported that both diets lessened fatigue and improved quality of life.
Although the benefits of the Wahls Protocol are promising, new studies are emerging to better understand exactly how much these lifestyle changes may improve MS symptoms.

Additional Lifestyle Recommendations of the Wahls Protocol
Beyond diet, the Wahls Protocol emphasizes the importance of other lifestyle factors in supporting overall health and well-being. These recommendations include:
- Exercise: Regular physical activity is encouraged to maintain muscle strength, improve cardiovascular health, and reduce fatigue.
- Stress Management: Stress-reduction techniques, such as meditation and yoga, are recommended to mitigate the negative effects of stress on the body.
- Sleep Hygiene: Prioritizing adequate sleep is crucial for immune function, brain health, and overall well-being.
- Sun Exposure: Safe sun exposure is encouraged to promote vitamin D production, which is essential for immune function and bone health.
Potential Benefits of the Wahls Protocol
The Wahls Protocol has been reported to provide several potential benefits, including:
- Reduced Fatigue: Many individuals following the Wahls Protocol report a reduction in fatigue, a common and debilitating symptom of MS and other autoimmune conditions.
- Improved Quality of Life: The diet and lifestyle changes associated with the Wahls Protocol can contribute to an improved overall quality of life.
- Weight Management: The focus on whole, unprocessed foods can aid in weight management and promote a healthy body weight.
- Improved Gut Health: The emphasis on vegetables, fruits, and fermented foods can support a healthy gut microbiome, which plays a crucial role in immune function and overall health.
- Reduced Inflammation: The elimination of processed foods, added sugars, gluten, and dairy can help reduce inflammation throughout the body.
Considerations and Precautions
- Consult with a Healthcare Professional: Before starting the Wahls Protocol, it's crucial to consult with a healthcare professional, particularly if you have any underlying health conditions or are taking medications.
- Nutrient Deficiencies: The Wahls Protocol excludes certain food groups, such as dairy and eggs, which can increase the risk of nutrient deficiencies, particularly vitamin B12. Supplementation may be necessary.
- Calorie Intake: It's essential to ensure adequate calorie intake while following the Wahls Protocol, as the focus on vegetables and fruits may lead to a reduction in overall calorie consumption.
- Individual Variability: The Wahls Protocol may not be suitable for everyone, and individual responses may vary. It's important to listen to your body and adjust the protocol as needed.
