What this Trial Is About
The investigators seek to better understand how a single high-fat meal impacts gut, immune, and vascular outcomes in individuals with "metabolically healthy obesity" (obesity and largely normal cardiometabolic profile) and "metabolically healthy normal-weight individuals." Second, the investigators seek to understand how a prebiotic fiber (inulin) impacts gut, immune, and vascular outcomes in individuals with "metabolically healthy obesity."
