First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study looks at how the bacteria in your gut and your body's response to fasting influence the way you process dietary fiber. Researchers will give 115 healthy adults different fibers during intermittent fasting and track changes in their gut microbes and blood sugar levels. The goal is to understand why people respond differently to fiber, which could lead to personalized diet advice.
