Reversing Multiple Sclerosis

Ancestral foods, medical ketosis, nervous system work, and the microbial terrain of remyelination

A Note Before You Begin

Multiple sclerosis has been framed for a long time as an incurable, progressive disease, something a person can only manage, never resolve. That story does not match the lived experience of the people you will meet in this article. MS responds to terrain. When the soil changes, the nervous system has shown again and again that it can quiet the inflammation, repair the myelin, and return function.

The work is slow and layered, but the direction it travels is forward. Read this with the same curiosity I ask of every client: not pressure, not perfection, just willingness to rebuild what has been worn down.

What Multiple Sclerosis Actually Is

Multiple sclerosis is described in conventional terms as an autoimmune disease in which the body attacks the myelin sheath, the fatty insulation surrounding nerve fibres in the brain and spinal cord. As the myelin breaks down, electrical signals travel more slowly and erratically, producing the familiar pattern of fatigue, numbness, tingling, weakness, balance trouble, blurred vision, brain fog, and the relapsing-remitting flares that characterise the early years of the disease.

This description is accurate as far as it goes. But it stops short of asking the question that matters most: why is the immune system attacking myelin in the first place?

The terrain answer, and the one that opens the door to reversal, is that the immune system is not malfunctioning. It is responding to an environment that has gone out of balance. Repair the environment, and the attack subsides.

The EBV Connection

In 2022 a landmark Harvard study (Bjornevik et al., Science) followed more than ten million U.S. military service members over twenty years and demonstrated that the risk of developing MS rises 32-fold after Epstein-Barr virus infection, and essentially zero MS cases occurred in people who never contracted EBV. The biomarker of nerve degeneration that signals MS onset rises only after EBV exposure, never before. The researchers concluded that EBV is almost certainly the leading cause of MS.

This is enormous news for terrain practitioners. It means MS is not random. It is a downstream consequence of a chronic viral infection in a body whose terrain can no longer hold it in check. The work of reversal becomes the same work we already know how to do: quiet the virus, rebuild the body that allowed reactivation, and remyelinate the nerves while the inflammation cools.

Why MS Is Reversible: The Five Pillars

Across the documented recoveries, Terry Wahls, Matt Embry, Ginamarie, Xavier, and many quieter cases inside functional medicine practices, the same pattern keeps emerging. People who reverse MS do five things at once. Each pillar matters, and the protocol below is built around them.

• Ancestral, nutrient-dense food that removes the inflammatory triggers and floods the body with the raw materials of myelin repair.
• Medical ketosis that fuels the brain on ketones, lowers neuroinflammation, and gives oligodendrocytes the substrate to rebuild myelin.
• Microbial restoration that corrects the dysbiosis pattern that maintains immune dysregulation.
• Nervous system work that returns the body to a parasympathetic state where remyelination can actually happen.
• Vitamin D, sunlight, and circadian alignment that drive both immune modulation and the stem cell signal for remyelination.

Pillar One: Ancestral Foods

The single most consistent observation across MS recoveries is dietary. People who reverse MS change what they eat, radically, and for a long time.

Where the well-known recovery stories sometimes diverge from one another is in how much plant matter they include. Some protocols (the Wahls and Best Bet diets are the famous examples) emphasise very large vegetable intakes alongside the elimination of grains, dairy, and seed oils. Others, including the ARP framework I teach, anchor recovery in animal foods and use plants sparingly and strategically.

Both approaches share an early phase of relief: any protocol that strips out gluten, processed sugar, casein, and seed oils will reduce inflammation quickly. The divergence shows up over time. Plant-heavy frameworks tend to plateau or backslide in the second and third year as the antinutrient burden accumulates and the gut, having been asked to do the work of an obligate herbivore it is not, begins to struggle again. The animal-based ancestral framework continues to deepen because it is built on what humans actually evolved to eat.

Why ARP Is Not a High-Plant Protocol

Plants defend themselves chemically. They cannot run from the animal eating them, so they produce compounds, lectins, oxalates, phytates, goitrogens, salicylates, glucosinolates, saponins, and the lighter polyphenol families, designed to discourage being consumed. These compounds are often called antinutrients because their primary action in the human body is to interfere with the absorption of minerals and the integrity of the gut wall.

For someone rebuilding from MS, this is a hard problem. The MS terrain is already characterised by intestinal permeability, micronutrient depletion, and immune hyperreactivity. Pouring oxalates from spinach and chard into that terrain, or lectins from beans and nightshades, or fermentable fibres from a daily mountain of cruciferous vegetables, asks the gut to do exactly what it cannot yet do. The early relief such protocols produce comes mostly from what they remove, not from the vegetables themselves. The long-term relief comes from doing more of the removal, including the removal of most plant matter.

This is why ARP food anchors are animal-derived: meat stock, organ meats, wild fish, pastured fats and yolks, raw fermented dairy. These foods are bioavailable, low in antinutrients, dense in the minerals and fat-soluble vitamins the MS brain is hungry for, and they do not require the gut to perform chemistry it has temporarily lost the capacity to perform.

Why We Still Keep Some Plants: Carefully

The plants that remain in the ARP framework are not there as a primary source of nutrition. They are there as food for specific keystone microbes, the birth microbes, that we need to seat back into the gut. Bifidobacterium does not eat meat. It eats human milk oligosaccharides, then a narrow set of plant-derived prebiotics: a pinch of acacia fibre, a teaspoon of well-cooked plantain, a cup of mild hibiscus tea, a small amount of apple pectin, the lactose in a teaspoon of raw milk.

The quantities are tiny on purpose. The goal is to feed a regrowing microbial community, not to fuel the body. We do not eat nine cups of vegetables a day; we offer a measured pinch of plantain fibre so Bifidobacterium has something to ferment, then continue feeding the body with the animal foods it actually runs on.

Amounts of these plant feeders stay small until either the two-year mark on protocol or three months of symptom remission, whichever comes first. After that, the body will tell you what it can integrate.

The ARP Food Anchor for MS

Meat stock (not bone broth), glycine, proline, and gelatin to rebuild the gut lining that drives systemic inflammation in MS. 3-6 mugs per day in the first months.

Organ meats, liver, heart, kidney. Liver in particular delivers vitamin A, copper, B12, and choline that the MS brain is hungry for.

Wild fatty fish, sardines, salmon, mackerel, herring. Omega-3 DHA is structurally required for myelin synthesis.

Pastured egg yolks, soft-yolked or raw. Choline and phospholipids are myelin building blocks.

Pastured ruminant meat and fat, ground beef, lamb, beef close to the bone; tallow, ghee, butter, suet. The ketogenic fuel base.

Raw A2/A2 fermented dairy, kefir, raw cheese, properly cultured yogurt. Reseeds the gut. Skip if you carry strong dairy reactivity.

Tiny, targeted plant feeders (Phase 3 onward, in very small amounts), cooked carrots and onion/garlic for gentle prebiotic action, plus pinches of plantain, acacia fibre, hibiscus, apple pectin, and lactose to feed the birth microbes. Quantities stay small for years.

What comes off the menu

Gluten and all grains; legumes; nightshades (tomato, pepper, eggplant, white potato); seed oils; conventional A1 dairy; processed sugar; high-oxalate vegetables (spinach, chard, almonds, sweet potato) and high-fermentable vegetables in large quantities.

These are not removed forever. They are removed for as long as the immune system needs to stop seeing food itself as a trigger, and in the case of seed oils, conventional dairy, and ultra-processed foods, they generally stay out for good. The body simply does better without them.

Pillar Two: Medical Ketosis

Ketosis is the metabolic state in which the body, deprived of glucose, shifts to burning fat for fuel and producing ketone bodies, beta-hydroxybutyrate, acetoacetate, and acetone, which the brain uses preferentially when they are available. For an inflamed MS brain, ketones are a different kind of fuel: cleaner, anti-inflammatory, and signalling rather than just energetic.

What the Studies Show

A 2022 Phase II clinical trial published in the Journal of Neurology, Neurosurgery and Psychiatry followed 65 people with relapsing-remitting MS on a ketogenic diet for six months. Results: significant reductions in fatigue, depression, and neurological disability scores; improvements in the 6-minute walk test and the Nine-Hole Peg Test of fine motor function; reductions in adipose-related inflammatory markers; and meaningful gains in overall quality of life.

A 2023 follow-up at the University of Virginia confirmed and extended these findings, noting that benefits appear to persist long after the trial period in people who maintain ketosis.

A 2024 systematic review and meta-analysis in Multiple Sclerosis and Related Disorders concluded that ketogenic interventions modulate the inflammatory cascade specifically implicated in demyelination. Beta-hydroxybutyrate, the body’s primary ketone, suppresses the NLRP3 inflammasome, the same inflammatory pathway upregulated in active MS lesions. Ketones also support mitochondrial efficiency in neurons whose energy metabolism has been compromised by inflammation.

How to Enter Ketosis Safely

Targets for therapeutic ketosis in the MS context are roughly 60 g protein per day, 20-30 g carbohydrate per day, and abundant fat, generally one-quarter to one-half cup of ghee, butter, tallow, or cultured cream added to meals daily once the gut tolerates it. Build the fat slowly: add one teaspoon per week, holding each level for several days, until the body adapts.

In my framework, ketosis is not begun on day one. It is layered in after the gut and mucosa have stabilised, typically beginning around the start of Phase 2, so that fat absorption is intact and the bile flow is working. Forcing ketosis on a damaged gut produces nausea and fat malabsorption, not ketones.

Pillar Three: Microbial Restoration

People with MS reliably carry a distinctive gut signature. Multiple comparative studies (most recently in Scientific Reports, 2024 and 2025) describe a consistent pattern of depleted beneficial organisms and overgrown opportunists. Restoring this terrain is one of the most leverage-heavy moves in the entire protocol, because the gut is where systemic immune training begins.

The MS Dysbiosis Pattern

The Microbial Stack for MS

The ARP microbial protocol for MS builds in three layers, each addressing a specific lever in the dysbiosis pattern.

Bifidobacterium longum BB536 and Bifidobacterium infantis, the most depleted genus in MS, and the deepest Treg trainers we have. Begin here.

Lactobacillus plantarum 299V, produces bacteriocins, restores mucosal IgA, competes with the gram-negative overgrowths driving endotoxemia.

Lactobacillus reuteri DSM 17938, specifically supports neurological terrain via the oxytocin-dopamine-vagal axis. Particularly relevant for cognitive symptoms.

Bacillus subtilis HU58, soil-based housekeeper that displaces opportunists and produces compounds that support oligodendrocyte function.

Saccharomyces boulardii CNCM I-745, targets intracellular environments and quiets the Th17 inflammatory pattern.

Lactoferrin, iron-sequestering toxin neutraliser that also reduces blood-brain barrier permeability, a critical lever in active MS.

Luteolin, crosses the blood-brain barrier, calms microglial activation, and supports the EBV-quieting work directly. Foundational for neuroinflammation.

HMOs (human milk oligosaccharides), the primary food for Bifidobacterium. Without HMOs the Bifidos cannot establish.

Daily Sequence

As with all ARP pathogen and microbial protocols, the stack is taken in a once-daily, three-hour timed sequence so each layer clears the way for the next.

Pillar Four: Nervous System Work

Myelin does not repair in a body stuck in sympathetic activation. The signal to remyelinate, to lay down new oligodendrocyte sheaths around demyelinated axons, comes from the parasympathetic branch, specifically through the vagus nerve. A nervous system locked in stress, vigilance, or fight-or-flight cannot rebuild myelin no matter how good the diet.

What the Research Shows

A growing body of preclinical work has shown that vagus nerve stimulation directly enhances remyelination.

A 2024 study in Brain Stimulation demonstrated that VNS increased the generation of myelinating oligodendrocytes and decreased innate neuroinflammation in a demyelination model.

A separate 2024 paper in PNAS demonstrated that electrical stimulation of the vagus nerve reduced inflammation and disease activity in the standard rat model of MS (EAE).

A 2024 paper in Nature Neuroscience showed that paired vagus nerve stimulation produces precise remyelination and motor recovery after myelin loss when combined with rehabilitative movement, a finding that maps directly onto what gentle yoga, tai chi, and movement-with-breathwork protocols do non-invasively in functional medicine practices.

The ARP Nervous System Practice

Vagus tone is built through repetition. The practices below are not optional in the MS protocol, they are the signal that tells the body it is safe to rebuild.

Twice-daily guided body scans, one in the first part of the morning, one as you settle into sleep. This is the single most direct vagal tone practice we have.

Slow, intentional nasal breathing, extended exhale (4 in, 6-8 out). Several minutes, several times per day.

Cold exposure, face dunks, cold rinses, or short cold showers. Activates the dive reflex, which is mediated by the vagus.

Humming, chanting, gargling, singing, mechanically tone the vagus through the throat. Do them throughout the day.

Gentle movement, walking outside, yin yoga, tai chi. Pair movement with breath. Avoid pushing into exhaustion.

Grounding, bare feet on soil, grass, or sand for 20-30 minutes daily. Direct electron transfer and parasympathetic signalling at once.

Detox baths, Epsom salt, baking soda, sea salt, optional vitamin C and bentonite. 2-3 times per week. Delivers magnesium through the skin and quiets the nervous system at the same time.

Pillar Five: Vitamin D, Sun, and Latitude

MS is one of the most latitude-dependent diseases known to medicine. Prevalence rises sharply the further from the equator a population lives. People who grew up at higher latitudes, who spent childhood indoors, who avoid the sun, or who run chronically deficient in vitamin D are at substantially higher risk of developing MS, and the same people, once diagnosed, show worse outcomes.

A 2015 international cohort study of more than 2,500 people with MS (BMC Neurology) found that latitude, deliberate sun exposure, and vitamin D supplementation all independently predicted disability scores, relapse rates, and quality of life. Higher serum vitamin D correlated with lower MS severity, fewer relapses, and slower disability accumulation.

Vitamin D does more than modulate the immune system. The active form, 1,25(OH)2D3, drives the differentiation of neural stem cells into oligodendrocytes, the very cells that produce myelin. Sun and vitamin D are, mechanistically, a remyelination signal.

The Practice

Sun on bare skin for 15-30 minutes daily, ideally between 10 a.m. and 2 p.m. when UVB is available. Build slowly. No sunglasses, the eyes need the light too.

Vitamin D3 supplementation of 5,000-10,000 IU daily with K2 in the months without strong sun. Test serum 25-OH-D and target the upper end of the reference range (60-100 ng/mL) rather than just the floor.

Cod liver oil, natural source of vitamin A, D, and EPA/DHA together. The combination is what the body uses; isolated D works less well alone.

The Phased Plan at a Glance

Three overlapping phases. Each builds on the one before. Move through them in order.

Living Proof: Recoveries in the ARP Direction

Scientific studies are slow, expensive, and conservative. Lived recoveries are faster, messier, and harder to dismiss. Below are some of the documented MS reversal stories that move in the same direction as the ARP framework, heavy emphasis on animal foods, deliberate gut and nervous-system work, and the willingness to stay with the protocol long enough for the terrain to actually shift.

Several of these people use the word “carnivore” or “keto-carnivore” rather than “ancestral,” and the specific food lists differ in detail. What unites them is the direction of travel: away from plant-heavy frameworks and toward dense, bioavailable animal nutrition.

Ginamarie: Keto-Carnivore Remission

Diagnosed with MS at 24, walking with assistance by 32, and facing disability. She moved to a keto-carnivore framework, animal foods, animal fats, no grains, no plants in any meaningful quantity, and reports complete remission of MS symptoms. Three years medication-free with no relapses at the time of her interview. Her case is documented through the Revero clinical network and is one of the cleanest examples of an MS terrain that responds to the exact food framework ARP teaches.

Xavier: Eight Years Vegan, Then Carnivore

Xavier spent eight years on a vegan diet, during which his MS progressively worsened. In May 2021 he reversed course entirely and shifted to a fully carnivore framework. He reports near-full remission of MS symptoms, and notes that any dietary deviation back toward plant matter brings symptoms back, direct, real-time confirmation that the lever is the food.

Mary Ruddick’s Recovery Framework

Mary Ruddick is a nutritionist and ancestral-health researcher who reversed her own severe autoimmune dysautonomia, she was bedbound, tube-fed, and given a terminal prognosis, using an animal-based ancestral diet, fermented foods, sunlight, and nervous-system regulation. She now teaches the same framework to clients with MS and other autoimmune-pattern conditions and reports consistent results. The ARP Phase 3 birth-microbe feeder list (plantain, acacia, HMOs, lactose, hibiscus) is drawn from her work and represents the considered position of someone who has personally walked the path from severe illness to full function on a primarily animal-based protocol.

The Gut-Healing Lineage

The gut healing protocols that came before ARP were built on the same meat-stock, fermented-dairy, animal-fat foundation that anchors ARP. Many of the MS recoveries documented in that literature follow the same pattern: months of meat stock and animal foods, careful staged reintroduction, no large vegetable loads in early phases, deliberate microbial reseeding. That lineage is the source of much of the foundational understanding that what plants we do eat must be cooked soft, introduced slowly, and never carry the nutritional weight of the diet.

The Carnivore Community

Outside the formal protocols, a growing number of MS patients have documented reversals on plain carnivore, beef, eggs, butter, salt, water, through practitioner networks like Revero, the work of Dr. Shawn Baker, and Dr. Ken Berry. The pattern is consistent enough that it has become difficult to dismiss. The carnivore framework is the simplest end of the same spectrum ARP works on: when in doubt about which plants are causing trouble, the answer is to remove all of them and see what happens. In a meaningful percentage of MS cases, what happens is remission.

Proof of Concept: Dr. Terry Wahls and Matt Embry

The two most famous public faces of MS reversal, Dr. Terry Wahls, who walked out of her tilt-recline wheelchair, and Matt Embry, more than thirty years symptom-free since age nineteen, followed plant-heavier frameworks than ARP teaches. Their stories are still relevant here because they proved the larger point: MS reverses. The body remyelinates. Function returns.

What their experience demonstrates is the direction; what the carnivore, gut healing, and ARP recoveries demonstrate is that the same reversal happens with fewer plants and more animal foods, and that the resulting terrain holds longer.

The Pattern

Every documented recovery shares the same elements: removal of inflammatory foods (especially gluten, casein, sugar, seed oils, and large fermentable plant loads), heavy emphasis on animal foods and fats, deliberate gut and microbial work, sun and vitamin D, somatic and nervous-system practice, and time. The exact food list varies. The direction does not.

A Closing Word

The hardest thing about an MS diagnosis is the story that comes attached to it: that this is permanent, that nothing can be done, that decline is the only direction. The body’s actual capacity is much larger than the story allows.

Nerves remyelinate. Inflammation cools. Energy returns. People walk again, work again, ride bicycles again.

The protocol is not a quick fix. It is the slow rebuilding of a terrain that has been worn down, usually for decades, by inflammation, viral burden, depleted nutrition, and a nervous system stuck in vigilance. We rebuild the soil, and the body does what the body has always known how to do.

Body, mind, soul. Tend the body well, and the nerves remember.
