What is MRT food-sensitivity testing?

LEAP — Lifestyle, Eating And Performance — is the structured dietary protocol built around MRT results. After the test, a LEAP-trained dietitian designs an initial elimination phase using foods that scored well on your panel, then carefully reintroduces other foods in a planned sequence.

The protocol is where the value lives. An MRT result without a clinician's protocol around it tends to become 'a long list of foods to avoid' — exactly the wrong outcome. The whole point is to end with a wider, more sustainable diet than you started with, not a more restricted one.

A true food allergy is an IgE-mediated immune reaction — typically rapid, sometimes severe (hives, swelling, anaphylaxis). Allergies are diagnosed and managed by an allergist using skin or blood testing and history. If you suspect a food allergy, the right path is an allergist, not a sensitivity test.

A food sensitivity is a broader, less precisely defined category: delayed, non-life-threatening reactions that may involve different immune mechanisms or none at all. MRT is intended for this sensitivity category; it does not diagnose allergies and is not a substitute for allergy testing.

MRT is most useful when symptoms are persistent, the picture is unclear, and the result is likely to genuinely change the plan. Common situations clients ask about:

MRT isn't a screening test for the general population, isn't a substitute for medical work-up of GI symptoms, and isn't appropriate during active eating-disorder treatment. It's also not how you diagnose celiac disease, IBD, SIBO or a true food allergy — each of those needs its own pathway with the right specialist.

It's worth saying plainly: food sensitivity testing has earned a mixed reputation, and a lot of that is fair. The difference between useful and harmful is almost entirely about the clinician interpreting the result and the reintroduction protocol that follows.

Leila is MRT-certified and trained in the LEAP protocol. We use MRT when it's likely to change the plan — paired with a structured reintroduction designed to end with a wider, more sustainable diet. We skip it when it isn't the right tool. The MRT service page has the full process, what's included, insurance details and FAQs.
