Dr. Terry Wahls was diagnosed with multiple sclerosis in 2000. By 2007, she relied on a tilt-recline wheelchair. Instead of accepting that trajectory, she researched how diet could support mitochondrial health and brain function. The result was the Wahls Protocol—a nutrient-dense eating framework that overlaps with the Autoimmune Protocol (AIP) but has its own distinct priorities. Here's what it emphasizes, how it differs from AIP, and what to expect if you try it.
Where the Wahls Protocol Comes From
Dr. Wahls was diagnosed with relapsing-remitting multiple sclerosis in 2000. By 2007, her condition had progressed to the point where she used a tilt-recline wheelchair. Rather than accept further decline, she began researching the role of nutrition in mitochondrial health and brain function. She designed a diet based on the micronutrient needs of the brain and immune system, drawing from paleo principles but adding specific targets for vegetables, sulfur-rich foods, and omega-3 fatty acids. Within a year, she reported walking without a cane, and she later published her protocol in both academic and consumer formats.
The protocol exists in several tiers. The most well-known is the Wahls Protocol (often called Wahls Paleo), which is the version most people encounter first. A more restrictive version, Wahls Paleo Plus, includes intermittent fasting and a lower carbohydrate intake. For readers already familiar with AIP, the standard Wahls Protocol will feel like a cousin — similar in many ways, but with different priorities and rules.
Core Principles of the Wahls Protocol
Unlike strict elimination diets that begin by removing a long list of foods, the Wahls Protocol starts with addition. The primary focus is on consuming nine cups of vegetables and fruits per day, organized into three categories:
- Leafy greens and sulfur-rich vegetables — three cups of kale, chard, spinach, arugula, cabbage, broccoli, cauliflower, or Brussels sprouts. These provide folate, vitamin K, and sulfur compounds that support detoxification pathways.
- Colorful fruits and vegetables — three cups of deeply pigmented produce such as beets, carrots, berries, red peppers, squash, and tomatoes. These supply polyphenols and antioxidants that reduce oxidative stress.
- Omega-3-rich foods and organ meats — the remaining three cups come from nutrient-dense animal foods like liver, heart, kidney, and fatty fish (salmon, mackerel, sardines). Organ meats are particularly emphasized because they contain high levels of B vitamins, coenzyme Q10, and minerals that support mitochondrial function.
Beyond the nine-cup target, the protocol encourages high-quality protein from grass-fed meat, wild-caught fish, and pastured eggs. It also includes seaweed, fermented vegetables, and bone broth for additional minerals and gut-supportive compounds. Grains, legumes, dairy, eggs (if you have an intolerance), and processed foods are excluded, similar to AIP. However, the Wahls Protocol does allow certain foods that AIP restricts, such as raw egg yolks (if tolerated) and some seeds like sesame and flax, depending on the tier.
How It Differs from AIP
If you have already been following AIP, you might wonder whether switching to the Wahls Protocol would add anything new. Here are the main differences:
- Addition before elimination. AIP begins by removing a broad list of potential triggers and then adds foods back systematically. The Wahls Protocol also eliminates common offenders (gluten, dairy, processed foods), but it places far more emphasis on hitting specific vegetable and organ meat targets from day one. The assumption is that nutrient density itself supports healing, and for some people, that focus alone reduces symptoms without needing a prolonged elimination phase.
- Organ meats are non-negotiable. AIP encourages organ meats as a nutrient-dense option, but the Wahls Protocol treats them as a daily requirement. If you struggle with the taste or texture of liver, the protocol includes strategies like mixing small amounts into ground meat or using freeze-dried organ capsules (though as always, supplements should be discussed with your healthcare provider).
- Carbohydrate levels vary. Standard Wahls Protocol is moderate in carbohydrates from vegetables and fruit. Wahls Paleo Plus is lower in carbs and includes a 16-hour overnight fast. AIP does not prescribe specific carbohydrate ratios or fasting windows, so this is a meaningful fork if you are considering which approach fits your metabolic needs.
- Seed and spice allowances. AIP excludes all seeds and seed-based spices during the elimination phase. The Wahls Protocol permits certain seeds (flax, sesame, sunflower) and spices like cumin and coriander, assuming you tolerate them. This can make the diet feel less restrictive for some people, though it also means you need to gauge your own reactions carefully if you have known sensitivities.
Practical Considerations for Daily Life
Adopting the Wahls Protocol requires significant kitchen time, especially in the beginning. Nine cups of produce per day is a lot of chopping, steaming, and sautéing. Batch cooking becomes essential. A practical strategy is to prepare large batches of roasted vegetables, cooked greens, and organ meat patties twice per week, then assemble meals from those components. Soups and stews that combine bone broth, leafy greens, and diced organ meats are efficient ways to hit multiple targets in one dish.
For those who travel frequently or have limited cooking energy, the protocol can feel daunting. Some people find it helpful to start with a less intensive version — aiming for six cups of vegetables rather than nine, or incorporating liver once per week instead of daily — and build up gradually. The protocol is not a pass-fail system; the research behind it suggests a dose-response relationship, meaning more nutrient density likely confers more benefit, but any increase over a standard Western diet is a step forward.
If you are currently following AIP and considering the Wahls Protocol, you might find it useful to keep a food and symptom journal for a few weeks to compare how your body responds to the higher vegetable load and the inclusion of seeds. The mindset of an elimination diet — patience, curiosity, and self-compassion — applies here as well. No single protocol works for everyone, and the goal is to find the pattern that supports your digestion, energy, and overall well-being without creating unnecessary stress around food.
Who Might Benefit from Exploring the Wahls Protocol
The protocol was originally designed for autoimmune neurological conditions, but its principles have been adopted by people with a wide range of health concerns, including chronic fatigue, digestive issues, and metabolic dysfunction. The heavy emphasis on micronutrients, omega-3s, and phytonutrients makes it a plausible option for anyone who feels they have not responded well to standard paleo or AIP alone. If you have been eating an AIP template but still struggle with low energy or poor digestion, the additional focus on organ meats and vegetable volume might fill gaps that your current diet is missing.
That said, the protocol is not a cure or a guaranteed solution. It is a dietary framework supported by mechanistic reasoning and case studies, not large randomized controlled trials for most conditions. If you have a chronic illness or persistent gastrointestinal symptoms, it is important to work with a knowledgeable healthcare professional who can help you implement the protocol safely and monitor your progress.

One Step at a Time
Start with a single, concrete change. Add an extra cup of leafy greens to your lunch—shredded kale in a salad or wilted spinach in a stir-fry. Commit to cooking liver once this week: mix a small amount into ground beef for burgers or try a liver pâté. Swap your usual vegetable oil for animal fat or coconut oil. Track how your digestion and energy shift over two weeks. Many people notice improved mental clarity or steadier energy before they hit the full nine-cup target. The protocol is flexible—adjust portions to what feels sustainable, and let your body guide the pace.
