Impaired Gut-Vascular Axis as a Unique Driver of Cardiovascular Disease in Metabolically Healthy Obesity
Ball State University
Summary
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."
Description
This study consists of two parts (part 1 and part 2) that are approved under the same IRB approval code. As a result, there is only one unique identifier for the entirety of this project. As a results, the investigators have included both parts in this registration. Part 1 of project: The investigators will recruit individuals with a BMI in the normal (18.5-24.9 kg/m2) or obesity (\>30.0 kg/m2) ranges from the Ball State University campus and surrounding communities. At a screening visit, the investigators will measure metabolic syndrome risk (blood pressure, triglycerides, glucose, HDL-C) t…

Interventions
- Dietary SupplementInulin Supplementation
Half of participants in part 2 will recieve supplemental inulin or placebo (maltodextrin).
- Dietary SupplementMaltodextrin (Placebo)
Half of participants in part 2 will recieve supplemental inulin or placebo (maltodextrin).
- OtherHigh-fat meal
All participants in part 1 (both metabolically healthy normal weight and metabolically healthy obesity) will consume a high-fat meal designed to invoke changes in gut, immune, and vascular parameters.
