What GAPS Says About Plant-Only and Vegan Diets

In Gut and Physiology Syndrome, Dr. Natasha Campbell-McBride describes a fully plant-only regimen as a form of fasting. Her explanation separates the cleansing role she assigns to plants from the feeding and building role she assigns to animal foods. It is different from both vegetarian eating that retains animal foods and the named More-Plant GAPS approach.^[1]

If those labels have become confusing, start with what is actually in the meals. A vegan pattern excludes everything from the animal kingdom. The vegetarian patterns discussed in the book retain some animal foods, especially eggs and full-fat dairy. More-Plant GAPS continues animal foods while adjusting their proportion to plant foods.^[1][2]

Plant Nutrients and Digestibility

Campbell-McBride begins by distinguishing the nutrients measured in a plant from the nutrients a digestive system can obtain from it. She points out that a laboratory can use extraction methods that are different from human digestion. Her argument makes preparation important, rather than treating a nutrient table as the whole story.^[1]

The chapter names fermentation, malting, sprouting and cooking as traditional ways to make plants more digestible and obtain more nourishment from them. It also argues that many modern processed foods have replaced those preparations. For a GAPS kitchen, the useful question is what the actual ingredient has been through before it reaches the plate.

That question applies to beans and nut flours as much as to vegetables. The More-Plant preparation guide covers the book’s named varieties, soaking instructions, cooked fruit and raw-food readiness.

Why the Book Keeps Animal Foods

The vegetarian chapter describes the body, apart from water, as largely protein and fat. Campbell-McBride emphasizes the continuing need for materials to replace aging cells and support growth in children. She favors animal foods because of their protein and fat composition and their role in her GAPS feeding framework.^[1]

Her discussion gives particular attention to the brain. It describes the brain’s physical structure and its production of active molecules as requiring protein, fat and cholesterol. The body makes cholesterol itself, and animal foods also provide it. This is part of the chapter’s explanation for retaining meat, fish, eggs and dairy, rather than treating plant energy as a replacement for every feeding function.

Campbell-McBride also reports clinical observations of anemia, poor stamina, digestive problems, muscle loss, low thyroid function and changes in cognitive or emotional functioning among people she describes as following long-term plant-only regimens. These are her reported observations in that discussion. They are not a family experience from our household.^[1]

Why She Calls Veganism a Fast

In the book’s account, plants supply considerable cleansing while the body still needs feeding materials. Campbell-McBride says a period of plant-only eating can initially feel good, but should not become a permanent lifestyle. When the body needs feeding again, she says animal foods must return. If that need remains unmet, she describes the breakdown of muscle and bone to support more essential organs.^[1]

The vegetarian chapter does not give everyone one number of days for a vegan fast. In “Feed Your Immune System Well,” Campbell-McBride says a fast should be fairly short and that animal foods need to return after cleansing. Her forty-one-day religious-fast account illustrates what she calls a vegan fast; it is not a prescribed GAPS duration.^[4]

This terminology is also separate from the book’s GAPS Liquid Fast, which has its own liquids, eligibility limits and instructions. Calling a regimen a vegan fast does not make it the same procedure.

The Early Cleansing Explanation

Campbell-McBride explains early improvements on a plant-based regimen through the cleansing substances in plants, particularly raw plants and fresh juices. She describes a later desire for animal foods, giving examples such as meat, cream, bacon or roast chicken, as the body asking to be fed.^[1]

Her chapter also discusses vegan nutritional cancer protocols as an example of deliberately emphasizing cleansing. That example belongs to her account of those protocols. It does not turn permanent plant-only eating into the standard GAPS approach or provide a cancer-treatment plan here.^[1]

The cleansing-and-building guide explains the two roles and why the book does not make their division absolute. Cooked and fermented plants can provide nourishment, while animal foods, particularly raw, also have a cleansing role in her framework.

The Older Eating-Disorders Discussion

The expanded Gut and Psychology Syndrome text uses the phrase “disguised starvation” in its eating-disorders discussion. Campbell-McBride presents it as her professional opinion about a restrictive, carbohydrate-heavy vegan pattern in a growing child. She identifies shortages of protein, zinc, fat-soluble vitamins A, D, E and K, B vitamins and magnesium in that discussion. Her concern is that nutrient shortages can deepen even when outward appearance does not look thin.^[3]

That chapter includes a named case in which vegetarian eating progressed to vegan and low-fat restriction, alongside pressure to lose weight and later illness. The case is not a timetable for every person who changes diets. The newer physiology book’s broader cleansing-and-feeding explanation is the framework used throughout this article.

Neither passage makes body size the only description of nutritional status. The older example explains why a child may not look thin, while the newer discussion describes other outward and functional changes. Keep the population and the author’s clinical account with those statements rather than turning them into a judgment about a person from a dietary label.

How Vegetarian Eating Differs

The 2020 book says a vegetarian diet can be maintained long term when it retains some animal foods, such as eggs and full-fat dairy, removes processed foods and includes substantial fermented food. It also describes traditional patterns containing fish or occasional meat. That is a wider use of the word vegetarian than a fully plant-only regimen.^[1]

Our vegetarian-eating question guide explains that discussion. It does not create a separate “Vegetarian GAPS” protocol. For the actual named plant-forward approach, use the More-Plant guide.

Frequently Asked Questions

Does the Book Set a Vegan-Fast Duration?

No universal duration is given in the vegetarian discussion. In “Feed Your Immune System Well,” Campbell-McBride says a fast should be fairly short and animal foods need to return after cleansing. The religious-fast example is not a GAPS schedule.^[4]

Are Plants Unimportant in This Framework?

No. The book gives them a cleansing role and recognizes glucose, micronutrients and some nourishment from prepared plants. Its concern is with using plant-only eating to replace the animal-food feeding foundation permanently.^[1]

Is More-Plant GAPS Vegan?

No. More-Plant GAPS keeps animal foods in the overall dietary pattern, even though some individual meals can be vegetarian.^[2]
