Lesson 8: Gut Health and GLP-1s
Lesson 8 is part of the Thriving on GLP-1s series, designed to help you build confidence, resilience, and sustainable habits without fear, restriction, or starting over.
Lesson 8 of 12 · Nutrition with Megan, RDN · Megan Ostler, MS, RDN
Does your digestion feel different on GLP-1 medications? In Lesson 8 of Thriving on GLP-1s, Registered Dietitian Megan Ostler explores how GLP-1s affect gut health and why simple, consistent nutrition habits (not restrictive protocols) are what actually support digestion, comfort, and long-term gut function.
This lesson helps you understand what gut health really means, recognize how GLP-1 medications change digestion and motility, and learn practical ways to stay comfortable and nourished instead of restricting foods or chasing microbiome trends.
This class focuses on gut health as a complex, adaptive system supported by simple inputs: fiber exposure, hydration, consistent eating patterns, and time (not supplements, elimination diets, or microbiome testing).
In this lesson, you'll learn:
- What gut health actually is and why it matters on GLP-1s
- How GLP-1 medications change digestion, motility, and gut signaling
- Why many gut symptoms on GLP-1s are functional and related to changes in intake, not pathology
- The truth about the microbiome: it's an ecosystem, not a scorecard
- How fiber and short-chain fatty acids (SCFAs) support gut barrier integrity, comfort, and motility
- Why probiotics aren't required for gut health (and when they might help)
- Why flexibility is especially important as appetite and digestion fluctuate on GLP-1s
