LEAP (Lifestyle, Eating, and Performance) Program at WomanCare

Millions of Americans struggle with food sensitivities, but identifying the triggers can be difficult, as reactions can be delayed by hours or even days. Traditional blood tests often fall short due to limited sensitivity or lack of testing for food chemicals. That’s where the LEAP (Lifestyle Eating and Performance) program comes in.

LEAP includes the MRT (Mediator Release Test), a patented blood test that can detect most food sensitivity reactions with over 90% accuracy. This comprehensive test is supported by independent studies and is the most reliable option available for identifying food and chemical sensitivities.

Common symptoms of food sensitivities include:

  • IBS (Irritable Bowel Syndrome)
  • Migraines
  • Fibromyalgia
  • Other chronic inflammation-related diseases

How LEAP Works

The LEAP program is designed to provide relief for those suffering from chronic conditions like IBS, migraines, fibromyalgia, and other inflammation-related diseases, which are often triggered by diet. Properly managing your diet is key to achieving long-term relief. Accurate identification of food triggers is the first step in gaining rapid, effective symptom improvement.

We collect your blood sample in our office, and you do not have to be fasting.

Your sample is FedExed to the lab overnight for testing.

After identifying food triggers, you’ll receive a personalized ImmunoCalm diet plan, divided into 5 phases, which outlines the foods to consume over the next four to six weeks.

After completing the initial phases, we help you adopt a rotation diet to prevent new food sensitivities from developing.

You’ll receive a 66-page guide with recipes, shopping tips, restaurant and travel advice, and additional resources for managing food sensitivities.

You’ll meet with our certified LEAP dietitian for 3 to 5 individualized follow-up visits to track your progress and adjust your diet as needed.

The LEAP process includes:

Expected Results

By removing reactive foods, your immune system has a chance to calm down, and many patients experience improvement in their symptoms within 10–14 days.

Common signs include bloating, fatigue, headaches, joint pain, skin issues, or mood changes after eating certain foods. These symptoms are often delayed, making them hard to trace without guidance or testing.

Food allergies cause an immediate immune response (like hives or anaphylaxis), while sensitivities are non-life-threatening but can cause ongoing inflammation and discomfort over time.

The Mediator Release Test (MRT) detects reactions to 170 foods and chemicals with up to 90% accuracy. It’s a powerful tool used in our LEAP Program to help identify and remove triggers contributing to chronic symptoms.

Many patients with IBS, migraines, fibromyalgia, joint pain, eczema, or fatigue have seen significant improvements by identifying food sensitivities and following a tailored elimination plan.

Yes. We work with you to understand not just what you eat, but why, offering realistic strategies to support healthy, sustainable weight loss or maintenance.

Not necessarily. We focus on finding what works for your body, not punishing restrictions. Our dietitians help you discover nourishing swaps and balanced choices you can actually enjoy.

Everybody is different, but many patients notice energy, digestion, and symptom relief improvements within the first few weeks of their personalized plan.

Not usually. Most patients can self-refer, but some insurance plans may require one—our team can help you check your plan and assist with next steps.

Only if needed. If your diet or symptoms suggest nutrient gaps, we may recommend pharmaceutical-grade supplements for better absorption and faster relief.

Most patients benefit from 3–5 visits, especially if enrolled in the LEAP Program. We tailor the frequency based on your goals, progress, and comfort level.
