The LEAP ImmunoCalm Diet: A Phase-by-Phase Guide to the Elimination Protocol
The LEAP ImmunoCalm Diet uses your MRT results to build a personalized elimination and reintroduction plan. This guide walks through all three phases, what to expect, and how to maximize your results.

The LEAP ImmunoCalm® Dietary Protocol is a structured elimination and reintroduction diet designed to reduce chronic inflammation caused by food and chemical sensitivities. Generic elimination diets remove broad food groups, but LEAP is personalized. It is built entirely from your individual MRT (Mediator Release Test) results.
This guide walks you through each phase of the protocol, what to expect, and practical tips for success.
How LEAP Works: The Core Principle
The LEAP protocol operates on a simple but powerful premise. If you stop eating the foods that trigger your immune system’s inflammatory response, your symptoms will improve.
Your MRT results identify exactly which foods and chemicals cause mediator release in your white blood cells. The LEAP diet then uses this data to:
- Build an initial diet from your least reactive foods (your safest options)
- Gradually reintroduce moderately reactive foods one at a time
- Establish a long-term, sustainable eating pattern that minimizes inflammation
This process is guided by a Certified LEAP Therapist (CLT), a dietitian or nutritionist with specialized training in food sensitivity management.
Phase 1: Elimination (Days 1–14)
What Happens
Your CLT selects approximately 20 to 25 of your lowest-reactive foods from your MRT results. For two weeks, you eat only these foods and nothing else. You cannot have seasonings, sauces, or condiments unless they are on your approved list.
Why It’s Strict
The goal is to give your immune system a complete rest. By eating only foods that produce virtually zero mediator release, you create a clean inflammatory baseline. Most patients begin noticing symptom improvement within 5 to 10 days.
What to Expect
- Days 1–3: Possible withdrawal symptoms (headaches, fatigue, irritability) as your body adjusts
- Days 4–7: Symptoms begin to stabilize, and many patients report the first noticeable improvement
- Days 8–14: Continued improvement, and you establish your “baseline” symptom level
Practical Tips
- Meal prep on Sunday for the week, as limited ingredients means simpler cooking
- Keep a symptom journal (rate symptoms 1 to 10 daily)
- Drink plenty of water. Some people use water as their only beverage in Phase 1
- Use the Wellbloom directory to find pre-made products that are safe for your Phase 1 list
Phase 2: Reintroduction (Weeks 3–8+)
What Happens
Once you have established your baseline, your CLT begins adding back foods one at a time. This typically starts with your yellow (moderately reactive) MRT foods. Each new food is introduced in isolation and monitored for 48 to 72 hours before adding the next one.
The Challenge Protocol
- Eat the challenge food 2 to 3 times on Day 1 in reasonable portions
- Return to your baseline diet for Days 2 and 3
- Monitor for any symptom flare-ups during the 72-hour window
- If no reaction: the food is added to your safe list
- If reaction occurs: remove the food and wait until symptoms clear before testing the next one
What to Expect
- Most yellow foods will pass the challenge, and your diet expands significantly
- Some surprises: a food you thought was safe may trigger a reaction, and vice versa
- This phase requires patience. Rushing the process can muddy your results
- Your CLT will adjust the order of reintroduction based on your symptom patterns
Phase 3: Maintenance (Ongoing)
What Happens
By Phase 3, you have a clear picture of your safe foods, your conditional foods (tolerated in moderation), and your trigger foods (to be avoided long-term). Your CLT helps you build a sustainable, nutritionally complete meal plan.
Key Principles
- Rotation: Even safe foods should be rotated every 3 to 4 days to prevent developing new sensitivities
- Variety: Eat as wide a variety of safe foods as possible for nutritional completeness
- Retesting: Some practitioners recommend retesting MRT after 6 to 12 months, as sensitivities can shift over time
- Label vigilance: Always check ingredient labels, because manufacturers change formulations frequently
How Wellbloom Supports Each Phase
| Phase | How Wellbloom Helps |
|---|---|
| Phase 1 (Elimination) | Search for products classified as Low Risk with zero MRT triggers. These are your safest packaged food options. |
| Phase 2 (Reintroduction) | Before challenging a new food, search for products containing it to plan meals. Check which products have 1 to 2 triggers for controlled testing. |
| Phase 3 (Maintenance) | Use the directory as an ongoing reference when grocery shopping. Filter by brand, category, or risk level to find safe options quickly. |
Finding a Certified LEAP Therapist
The LEAP protocol is designed to be administered by a Certified LEAP Therapist (CLT). These are licensed healthcare professionals (typically registered dietitians) who have completed advanced training in food sensitivity management through Oxford Biomedical Technologies.
Use our CLT directory to find a practitioner near you. Many CLTs offer telehealth consultations, so location doesn’t have to be a barrier.

The LEAP ImmunoCalm protocol should be followed under the supervision of a Certified LEAP Therapist (CLT) or qualified healthcare provider. Individual results vary. Always consult your physician before starting any elimination diet.
