Can a fiber supplement protect your heart after a fatty meal?

This study looks at how a single high-fat meal impacts the gut, immune system, and blood vessels in people with metabolically healthy obesity (obese but otherwise healthy) compared to normal-weight individuals. It also tests whether a prebiotic fiber called inulin can improve these outcomes. Researchers will measure markers of inflammation and blood vessel function over several hours and weeks. The goal is to understand why some people with obesity develop heart disease, even when their blood pressure and cholesterol are normal.
