Gut health as the ground everything grows from.
Almost every protocol in the practice, whether the presenting problem is thyroid, insulin, hormonal or inflammatory, starts with the gut. Not because gut health is fashionable. Because the gut is where nutrients are absorbed, where a large fraction of the immune system lives, and where the neurotransmitters that shape mood and appetite are produced.
Part 1. Why the gut is upstream of almost everything.
The gut does three jobs at once, and the second two are the reason a metabolic practitioner starts here. The first job is the obvious one: breaking down food and absorbing nutrients. If absorption is impaired, no amount of supplementation, dietary refinement or lifestyle work will move the biomarkers you would expect it to move.
The second job is immune modulation. Roughly 70 percent of the immune system sits in the gut-associated lymphoid tissue, and the gut lining is the surface across which the body decides what is food and what is threat. When that decision-making surface is inflamed, hyperpermeable, or populated by the wrong balance of microbes, the immune system runs on a low-grade alert that shows up as inflammation everywhere else. Thyroid antibodies, joint inflammation, skin conditions, endometriosis progression, insulin resistance, all of these have inflammatory components that trace back to what the gut is doing.
The third job is neurotransmitter production. Around 90 percent of the body's serotonin is produced in the gut, alongside meaningful amounts of dopamine, GABA and their precursors. The gut-brain axis is not a wellness metaphor; it is a bidirectional signalling relationship carried by the vagus nerve and by circulating microbial metabolites. A gut in poor condition is a nervous system running on lower baseline reserves, which is why anxiety, poor sleep, and low mood are so common alongside gut symptoms.
Part 1 draft to be extended with Maria's preferred stool-testing panels (which UK-available tests she runs, what she looks for), and how she explains the gut-immune connection to Clinic clients in the first session.
Part 2. What a gut-first protocol actually looks like.
A gut-first protocol is not a probiotic prescription and it is not a two-week detox. It is a structured sequence, usually three to four months long, that removes the inputs the gut is reacting to, repairs the gut lining, reseeds the microbiome with the right diversity, and only then reintroduces the foods that were pulled.
The remove step identifies and cuts what the body is currently reacting to. This can be gluten, dairy, alcohol, ultra-processed foods, or foods that a stool test flags as producing an inflammatory response in this particular person. It is temporary. The point is not to build a life around avoidance; the point is to give the gut lining a chance to heal without new insults arriving daily.
The repair step supports the intestinal lining directly. L-glutamine, zinc carnosine, deglycyrrhizinated liquorice, and specific plant compounds have evidence for reducing intestinal permeability and calming inflammation. The specific inputs depend on the person and the pattern.
The reseed step introduces diversity through fermented foods and, where appropriate, targeted probiotic strains chosen for the presenting condition. Not all probiotics do the same thing, and generic multi-strain products often do less than a well-chosen single strain matched to the client.
The reintroduce step brings back foods one at a time, with a two-to-three-day gap between each, watching for symptom return. The end state is usually broader than the client expected. Most reactive foods are reactive because the gut is inflamed; once the gut is healed, tolerance often comes back.
