From the dawn of the Atkins Diet, to the rapid rise in recent years of the Keto philosophy, there always seems to be new “miracle cures” and “superfoods” discussed and analysed by dietary experts.
Amidst this cacophony, the GAPS diet emerges—not as another fleeting trend, but as a comprehensive approach grounded in physiology and biochemistry. Aimed primarily at individuals grappling with complex gastrointestinal issues like ulcerative colitis and Crohn’s disease, the GAPS diet posits an audacious claim: The gut is not just a component of your digestive system; it’s a vanguard of your overall health.
Just as with every new dietary trend, there have been pages and pages of both academic and lifestyle text dedicated to analysing, critiquing and ultimately informing on the GAPS diet. So, here at Advanced Supplements, we’ve put our experts to task on dissecting the GAPS diet meticulously. In this article we’ll take a look at the diet’s origins which are steeped in scientific inquiry and its multi-staged approach designed for bio-individuality. We’ll examine its fundamental claim that the gut connects with the brain and analyse whether or not its philosophy of using nutritional therapy to address conditions that conventional medicine often finds baffling actually stands up.
So, prepare to challenge some of your existing beliefs about diet and health as we venture into the world of Gut and Psychology Syndrome (GAPS).
What Is The GAPS Diet?
GAPS is an acronym which stands for Gut and Psychology Syndrome. It rests on a foundational hypothesis that is both ambitious and polarising: that the state of one’s gastrointestinal tract is intrinsically linked to mental health.
Coined by Dr. Natasha Campbell-McBride, a neurologist and nutritionist, the GAPS framework diverges from conventional dietary protocols by asserting that a myriad of conditions—ranging from autism to depression—have their roots anchored deep within the gut microbiome. But this is no hastily sketched hypothesis; it finds its footing in an expanding body of scientific evidence that lends credence to the gut-brain axis, an intricate web of biochemical signalling occurring between the gastrointestinal tract and the nervous system.
The GAPS diet, also rather unconventionally, relies on many different stages. But, before we dive into these in any detail it’s pivotal to understand its biochemical underpinnings. At its core, the GAPS Diet is not merely a list of foods to avoid or consume; it’s an orchestrated approach aimed at recalibrating the delicate ecosystem of gut flora. This, in turn, purportedly ameliorates the synaptic communications within the brain, offering not just symptomatic relief but a holistic approach to well-being.
If these claims seem audacious, they are—but not without a thread of scientific rationale that weaves through the tapestry of emerging research in the fields of neurology and gastroenterology. As we peel back the layers, the question becomes: Is the GAPS Diet an avant-garde frontier in nutritional science or a well-intentioned misstep? Our aim is to look at its advantages as well as its criticisms and try to provide a balanced, nuanced perspective that goes beyond the hyperbole, dissecting the diet’s components and potential applications to provide you with a comprehensive understanding of this provocative approach to health.

The Stages of the GAPS Diet: A Symphony in Six Movements
When viewing the GAPS Diet as a framework, it becomes evident that it doesn’t just provide a regimen for people to follow and reap rewards from in the same way that diets like Keto do. It’s more like a symphony or an opera in that it happens across different parts or acts, with each stage acting as a movement that contributes to a harmonious whole. The diet has six distinct stages, each with a carefully curated list of foods and a dedicated purpose—ranging from healing the gut lining to reintroducing food diversity.
Stage 1: Basic Foods & Broths
In this opening movement, the emphasis is squarely on foods that are easiest to digest. Think of simmering broths from beef or chicken, accompanied by soft, cooked vegetables like carrots or cauliflower. This stage is akin to a reset button for your gut, preparing it for the intricate phases that follow.
Stage 2: Reintroducing Fats
At this point, fats like raw egg yolks and ghee take their bow. Introduced incrementally, these foods aid in expanding the gut’s ability to process a more diverse range of nutrients without it having to try and break down the much more complex carbohydrates and oils that have not yet been reintroduced.
Stage 3: Adding Fermented Foods
This phase ushers in nut butters and fermented foods, for example; sauerkraut. These additions build upon the gut’s newly reinforced integrity, laying the groundwork for the increasingly intricate stages that lie ahead.
Stage 4: Oils & Grilled Meats
Here, the rhythm shifts as grilled and roasted meats make their entrance, along with a generous drizzle of extra virgin olive oil. This stage signifies a significant milestone: the reintroduction of more ‘normal’ foods, albeit consumed with a heightened awareness of gut health.
Stage 5: High Sugar Fruits
In this vibrant chapter, fruits like homemade applesauce and pear sauce appear, along with fresh vegetable juices. The purpose? To slowly reincorporate a more colourful and varied food spectrum while maintaining the gut harmony which has been so far, hard worked for.
Stage 6: Complete Gut Harmony
The final movement is a celebration of diversity in diet, featuring everything from apples and cherries to coconut milk and dates. This concluding stage marks your gut’s readiness to manage a broad array of foods, ending the GAPS symphony on a triumphant note.

The Common Questions About The GAPS Diet
Now that we’ve outlined what the GAPS diet and how it works, and before we delve into the nuances of the GAPS diet’s advantages and disadvantages, let’s pause and address some of the most pressing questions that tend to emerge when contemplating this intricate dietary journey.
1. When Do I Know I Should Move to the Next Stage?
Moving through the GAPS stages isn’t merely a question of time; it’s an intricate dance with your own physiology. The key is to pay meticulous attention to your body’s signals. Experiencing a reduction in previously vexing symptoms can often be the green light to gracefully transition to the next stage.
2. Does the GAPS Diet Cause Constipation?
While the GAPS diet is designed to facilitate gut health, it isn’t devoid of potential side effects. Some individuals report constipation, particularly in the early stages. The inclusion of fermented foods and an awareness of adequate hydration can usually mitigate this issue.
3. How Do I Know If I Am Experiencing Food Sensitivity?
Subtle changes in digestion, mood, or even skin condition can be tell-tale signs. The GAPS diet is structured to introduce foods gradually, giving you the chance to observe these changes meticulously. Should you find any adverse effects, you’re advised to revert to the previous stage and consult healthcare guidance.
4. Does the GAPS Diet Cause Nausea?
Nausea can occasionally make an unwelcome guest appearance, particularly in the initial stages. This is often your body’s way of adjusting to a new nutritional landscape. Consuming broths and staying hydrated can offer relief.
5. Can I Add Supplements to the GAPS Diet?
While the essence of GAPS is rooted in whole foods, there’s room for nuanced supplementation. However, like a master painter adding final touches to a canvas, any supplementation should be judicious and consultative, aimed at complementing rather than replacing the diet’s core components.
A Balanced Analysis Of The GAPS Diet
As we alluded to in the introduction of this article, there has been an incredible amount of time and research done on the GAPS diet. Whilst some of this has found many supporting attributes of this dietary philosophy, there have been just as many aiming to debunk and discredit its effectiveness. Having trawled through much of both, we’re now going to present what we hope is a balanced analysis on the GAPS diet as a whole.
Advantages:
Well, first off, the GAPS diet stands as a remarkable divergence from conventional dietary protocols, precisely because it doesn’t aim to be merely a sticking plaster solution for symptoms. Instead, it offers a systemic recalibration of the gut microbiome with potential downstream effects on both mental and physical health. This aligns well with the growing scientific understanding of the gut-brain axis, making the GAPS approach appear less like a diet and more like a holistic and natural health strategy.
One of its notable strengths is the emphasis on whole, unprocessed foods rich in nutrients, which invariably means a move away from the processed, sugar-laden Western diet that has been implicated in various health issues. The diet has been touted for its versatility, applied to conditions ranging from Autism Spectrum Disorders to Irritable Bowel Syndrome (IBS).
Its principles of bio-individuality offer a degree of adaptability that caters to individual health needs. Additionally, by centering the spotlight on the gut, this diet serves as an educational platform, raising awareness about the importance of gastrointestinal health, and inspiring a more comprehensive lifestyle shift. Lastly, while conclusive evidence remains scant, anecdotal reports suggest the diet may reduce symptoms in inflammatory conditions like arthritis and certain autoimmune diseases.
Disadvantages:
While the advantages of the GAPS diet might sound compelling, it is not without its drawbacks. The most glaring is the lack of rigorous, long-term scientific studies validating its efficacy. Despite numerous testimonials, empirical evidence that meets the medical community’s standards remains limited. Coupled with this is the diet’s potential for nutritional gaps. Its restrictive nature, especially during the initial stages, could lead to nutritional deficiencies—a concern that escalates when applied to vulnerable groups like children or pregnant women. Financial and social costs are other barriers to consider; maintaining a diet rich in specialised foods can be economically taxing and socially isolating.
Perhaps one of its most complicated aspects is its inconsistent results; it seems to work wonders for some while offering minimal to no benefits for others. Finally, the GAPS diet demands a high degree of self-monitoring and awareness. Failure to accurately interpret one’s own bodily signals could lead to improper stage transitions, thereby hindering progress and potentially exacerbating symptoms.
All in all, the GAPS diet presents a complex tapestry of both promise and caution. Whether viewed as an avant-garde frontier in nutritional science or a well-intentioned misstep, its growing prominence reveals our increasing fascination with the profound links between our gut and overall health.

Final Thoughts
As we bring our exploration of the GAPS diet to a close, it’s evident that this isn’t just another dietary fad. Rooted in the burgeoning fields of neurology and gastroenterology, the GAPS diet holds a provocative thesis—that the health of your gut can be the compass directing the broader landscape of your well-being. Its staged approach to dietary adjustment offers a structured, albeit demanding, pathway for individuals searching for alternatives to traditional treatment for various conditions ranging from gastrointestinal issues to neurological disorders.
While the evidence supporting the GAPS diet is promising, it’s far from conclusive. The diet, like any ambitious scientific theory, has its fair share of supporters and sceptics.
The purpose of this article has been not to persuade but to inform, providing a nuanced understanding of its potential advantages and disadvantages. Your body is an intricate orchestra of physiological processes, and the GAPS diet suggests a particular form of nutritional music. Whether that tune harmonises with your own biological symphony is a personal question—one best answered in consultation with qualified medical professionals.
