Episode 61: AIP for Hashimoto’s — The Pioneering Abbott Pilot Study & Case Reports

Hashimoto’s thyroiditis is the most common autoimmune disease in the world—and yet many people continue to struggle with fatigue, brain fog, pain, and mood symptoms even when their thyroid labs look “normal.”

In this episode of the Autoimmune Wellness Podcast, Mickey Trescott continues the AIP Medical Research Review series with a deep dive into the very first clinical study ever conducted on the Autoimmune Protocol for Hashimoto’s thyroiditis. This community-supported pilot study, led by Dr. Rob Abbott and published in 2019, examined whether a structured AIP diet and lifestyle intervention could improve quality of life, inflammation, and symptom burden in adults with Hashimoto’s who were already medically stable.

Mickey walks through the full story behind the study—from the chance meeting that sparked the research, to the grassroots crowdfunding effort that made it possible. She breaks down the study design, participant profile, intervention structure, clinical measures, and results, including detailed case reports that offer rare insight into individual experiences.

This episode highlights a critical and often overlooked reality in Hashimoto’s care: meaningful improvements in how people feel and function can occur even when thyroid hormones and antibodies remain largely unchanged.

In this episode, you’ll learn:

1. How the first AIP study for Hashimoto’s thyroiditis came to be
2. Why Hashimoto’s patients often struggle despite “normal” thyroid labs
3. Who participated in the Abbott pilot study and why that matters
4. What the AIP intervention looked like in a clinical research setting
5. How diet, nutrient density, and lifestyle practices were integrated
6. Which clinical measures were used to assess symptoms, inflammation, and quality of life
7. What the study revealed about fatigue, pain, mood, and daily functioning
8. Why improvements occurred even though thyroid hormones stayed stable
9. What happened with thyroid antibodies and systemic inflammation
10. Why some participants required lower doses of thyroid medication
11. What the individual case reports reveal beyond group averages
12. Why this study remains a milestone for Hashimoto’s research today
13. Practical takeaways for using AIP to support Hashimoto’s now
