Meet sonia:
your AUTOIMMUNE
DISEASE SPECIALIST
Hello, I’m Sonia Sidle, a Functional Nutritional Therapy Practitioner (FNTP) certified by the Nutritional Therapy Association. I also hold certifications as a Certified Autoimmune Paleo Coach, a Certified Functional Blood Chemistry Specialist, a Restorative Wellness Practitioner and a Functional Supplement Specialist.
Originally from France, I now live in Texas with my spouse, our two children, and our two dogs.
My personal journey with autoimmune disease
My journey began after I was diagnosed with Hashimoto’s thyroiditis and later endometriosis. Despite years of conventional treatment, my symptoms -fatigue, brain fog, weight gain, and dry skin- lingered. I felt frustrated and stuck.
Everything changed when an integrative doctor introduced me to the AutoImmune Protocol (AIP), a nutrition and lifestyle framework designed to calm inflammation, health the gut lining, and restore balance. Within just three months, I experienced a profound transformation: my energy return, the brain fog lifted, and I finally felt like myself again.
Later when ou teenage son was diagnosed with Hashimoto’s, we turned to AIP for him as well. Despite his pediatrician’s doubt, his symptoms completely disappeared. Experiencing these transformations in our own family confirmed what I already felt in my heart: nutrition and lifestyle are powerful tools in navigating autoimmunity.
from personal healing to professional calling
These experiences inspired me to dedicate my career to helping others. I became a Functional Nutritional Therapy Practitioner (FNTP) and a Certified Autoimmune Paleo Coach, specializing in gut health, which is a cornerstone of autoimmune wellness.
Alongside my colleague Ludy de Menten, I co-created J’adopte l’AIP, a French-language program designed to help people transition to the Autoimmune Protocol in just six weeks. In 2024, we co-authored the book Soigner l’auto-immunité avec le protocole AIP, the first french language resource of its kind , complete with guidance and 60 AIP-compliant recipes.
Today as an autoimmune disease specialist, I work with clients worldwide -offering personalized nutrition, advanced functional testing, and lifestyle strategies that target root causes instead of masking symptoms.
my mission
I believe that living with an autoimmune condition doesn’t mean settling for constant fatigue, pain, or uncertainty. My mission is to empower you with knowledge, tools, and support you need to reclaim your health and feel confident in your body again.
