What this research studies

From your perspective, you would fast, drink a standardized mixed meal, and have blood drawn before and two hours after the meal. Researchers will measure around 600 small molecules in your blood to capture the body’s dynamic metabolic response. The team will compare how these post-meal changes differ within and between people to spot subtle signs of organ dysfunction that aren't visible at rest. Results could help identify who is entering early, more treatable stages of cardiometabolic disease.

Who could benefit from this research

Good fit: Adults willing to fast and undergo blood draws before and two hours after a standardized mixed meal, including people with various ages and body sizes, would be appropriate candidates.

Not a fit: People with advanced, diagnosed cardiometabolic disease or those unwilling/unable to attend in-person visits and blood draws may not benefit from participating.

Why it matters

Potential benefit: If successful, this work could enable earlier detection of metabolic changes that predict diabetes, obesity, or cardiovascular disease before symptoms appear.

How similar studies have performed: Prior studies show fasting metabolite patterns relate to cardiometabolic risk and meal-challenge tests are promising, but applying broad metabolomics to post-meal changes at this scale is relatively new.
