Certified LEAP Therapist Nutritionists and Dietitians
What is a Certified LEAP Therapist?
A Certified LEAP Therapist (CLT) is a dietitian who has received specialized training in food sensitivity and chronic condition management. They complete the LEAP (Lifestyle Eating and Performance) program, which focuses on identifying and managing food sensitivities to alleviate chronic conditions. CLTs are trained to use the Mediator Release Test (MRT), a blood test that measures inflammatory responses to various foods. This allows them to create individualized dietary plans tailored to each client's specific sensitivities and chronic health issues. By identifying and eliminating trigger foods, CLTs help clients reduce inflammation and manage chronic condition symptoms more effectively.
Who should work with a Certified LEAP Therapist?
Certified LEAP Therapists (CLTs) primarily work with clients who have chronic conditions or food sensitivities that may benefit from dietary modifications. These conditions include irritable bowel syndrome (IBS), Crohn’s disease, ulcerative colitis, fibromyalgia, rheumatoid arthritis, and polycystic ovary syndrome (PCOS). Many clients turn to CLTs when other interventions have failed or when they desire additional strategies to improve their symptoms beyond medication and conventional treatments. By tailoring diets to individual needs, CLTs help clients manage their conditions more effectively and enhance their overall quality of life.
What happens in a LEAP Therapy session?
The overall goal of LEAP Therapy is to help clients identify foods that may be triggering their symptoms and guide them through an elimination diet followed by a reintroduction phase. LEAP Therapy typically begins with the administration of a Mediator Release Test (MRT), which categorizes food sensitivities from "green" (non-reactive) to "red" (highly reactive). Based on these results, dietitians work with clients to create a diet plan that eliminates highly reactive foods while still promoting overall health and balance. Additionally, LEAP dietitians often advise clients on other lifestyle modification strategies, such as incorporating more anti-inflammatory foods (such as fruits, vegetables, and certain spices) into their diet.
What is the LEAP elimination diet?
The LEAP elimination diet is designed to help individuals identify specific foods that may be causing intolerance symptoms or contributing to chronic disease symptoms. When it is unclear which foods are triggering these issues, the LEAP elimination diet systematically removes and then reintroduces foods to identify specific triggering foods. This process often follows the completion of the Mediator Release Test (MRT), which offers insight into which foods might be problematic. By eliminating and reintroducing foods based on MRT results, clients can better understand their triggers and manage their symptoms more effectively.
