For ALS and other motor neuron diseases, Dr. Natasha Campbell-McBride describes repeated GAPS Introduction Diet cycles with Full GAPS periods between them. Her entry does not give a fixed length for either part. Understanding the food stages is useful, but the meal plan also needs to fit the person’s swallowing, nourishment and current care needs.[1][2]
Understand the Proposed Intro and Full GAPS Sequence
The ALS entry recommends several passes through Intro rather than one pass followed by a permanent move to Full GAPS. It does not say to repeat Intro monthly, restart on every symptom or spend two years in each Full GAPS interval. Those would be added rules.[1]
General starting exceptions still matter. The official Intro chart does not recommend Intro during pregnancy or nursing, or for severe constipation. For poor fat digestion or histamine problems, it describes starting with Full GAPS or tailoring Intro, including temporarily limiting particular broths or fermented foods. The 2020 book also recommends Full GAPS first for chronic constipation, with Intro attempted after constipation resolves.[4] Review those circumstances before assuming the ALS entry overrides them.[3]
The Intro and Full GAPS comparison explains the two food phases. Campbell-McBride states that she has no clinical experience treating ALS/MND; her recommendation applies her experience with other serious conditions, rather than reporting an ALS outcome.[1]
Plan Meals Around What the Person Can Eat
ALS can make chewing and swallowing harder and interfere with getting enough nourishment. A swallowing and nutrition plan may require particular food textures, fluid thicknesses or feeding support. A thin stock, raw vegetable or nut-based food is not automatically suitable because its GAPS stage permits it. Keep the prescribed swallowing and feeding plan in place when choosing meals.[2]
Write down the foods and textures already used successfully, who can help with preparation and which questions need the care team’s answer. This makes the stage chart a planning reference rather than a reason to attempt a food that does not fit the person’s current abilities.
Use the Correct Food Stage
The 2020 book gives the following progression. Each stage carries forward tolerated earlier foods. New foods begin in small amounts, and the pace follows individual symptoms rather than a fixed calendar.[4]
| Stage | What the Book Adds |
|---|---|
| Stage 1 | Homemade meat or fish stock, boiled meat and soft tissues, and soups with very soft vegetables with fibrous parts removed. Fermented vegetable juice begins gradually. Fermented dairy has its own tolerance and introduction sequence. |
| Stage 2 | Raw organic egg yolks separated from whites, then soft-boiled eggs when tolerated; slowly cooked stews and casseroles with fresh herbs, fermented fish and homemade ghee. Continue gradually increasing introduced probiotic foods. |
| Stage 3 | Ripe avocado; pancakes made from nut butter, eggs and peeled, deseeded squash; gently fried or scrambled eggs; onion cooked in fat; and small amounts of the fermented vegetables themselves. |
| Stage 4 | Roasted or grilled meat without burned pieces, cold-pressed olive oil added to meals, filtered carrot juice introduced gradually, and bread made with fermented nut or seed flour. |
| Stage 5 | Cooked apple; raw vegetables beginning with soft lettuce and peeled cucumber; then other tolerated raw vegetables. Apple, pineapple or mango may be added to already tolerated vegetable juice; citrus waits. |
| Stage 6 | Peeled raw apple, gradually more raw fruit and honey, and allowed sweet baking using dried fruit. Honey is already used in tea earlier; Stage 6 is not its first appearance. |
For Stage 4 juice, the book starts with a few spoonfuls of clear, filtered carrot juice, diluted with warm water or mixed with introduced homemade yogurt. It builds to a cup a day before adding celery, lettuce and mint. That sequence does not bring fruit juice into early Intro.[4]
The book describes a home skin sensitivity check for some introductions. It is not a diagnostic allergy test or clearance to retry a known allergen. Keep an established allergy plan in place.[4][10] The detailed stage guides above keep each food’s preparation and tolerance steps together.
Keep Meat Stock and Bone Broth Separate
The current official GAPS recipe guidance calls for meat stock made from raw meaty animal parts with bones, joints, fascia, cartilage and fat. It distinguishes this from long-cooked broth made from bare bones, and delays bone broth for at least a year, sometimes several years. Repeating Intro does not remove that distinction.[5]
Nut and seed preparation matters too. The 2020 Stage 4 bread uses fermented flour. Simply grinding purchased nuts is not the whole preparation, and the current official recipe guidance requires proper preparation of nuts, seeds and legumes.[4][5]
Build Full GAPS Meals From the Main Foods
The Full GAPS chapter centers meals on meat, fish, stock, eggs, tolerated fermented dairy and vegetables. Fruit and allowed baking are additions rather than replacements for the main meals. If beginning with Full GAPS, the book keeps fruit, nuts and baking out initially and brings them in gradually. It also recommends a gradual introduction of fermented foods.[6]
Full GAPS is broader than early Intro. Do not carry the early restriction on fibrous vegetables into a blanket Full GAPS ban. The GAPS food list gives the detailed allowed and avoided foods. Grains, refined sugar, potatoes, parsnips, yams and sweet potatoes remain excluded; raw honey and allowed fruit should not be confused with refined sugar.[6]
The book favors home-cooked fresh ingredients and animal fats for cooking. It also names coconut oil and ghee as stable cooking fats. Other good-quality cold-pressed plant oils are used on served food rather than heated.[6] Check the actual ingredients in purchased products, including dairy and processed foods, instead of assuming that every item with a familiar name fits.
Where Chelation Fits
After a year on the diet, the ALS entry says it may be sensible to consider the Andy Cutler Protocol for toxic metals, lead in particular, for at least two years while continuing GAPS. The wider chelation chapter says chronic-exposure cases may need a year or longer for the gut and detoxification system to be ready. It separately discusses acute exposure, which should not be managed by waiting for that anniversary.[1][7]
These are the author’s proposed timing and rationale, not a diagnosis of metal poisoning or a self-treatment schedule. Chelation can cause serious harm and requires medical evaluation and supervision.[9] This page does not supply chelating agents, doses or treatment rounds.
Do Not Turn the General Duration Into an Interval
In “Coming off the GAPS Diet,” Campbell-McBride says that the majority should follow strict GAPS for at least two years and have at least six months of normal digestion before introducing foods outside the diet. She describes faster recovery for some, longer periods for others and permanent Full GAPS for some people. The Full GAPS chapter separately says that health problems should be gone and the person should have been well for at least six months before considering coming off. These general statements do not set the duration between repeated Intro cycles or promise neurological recovery.[8]
In my home, GAPS cooking fits around homeschooling and second-shift work. Having the next meal and its preparation clear is useful; trying to rebuild the whole kitchen routine at once is harder. My Intro Stage 1–6 Batch-Cooking Guides are listed in the WFLI Shop for the food-preparation side of that work.
Begin with the current eating and feeding plan, then use the appropriate stage guide to identify meals to discuss and prepare. The ALS and GAPS overview explains the book’s scope, and the gut and toxin explanation follows its proposed mechanism.
