Comparing how healthy and obese individuals respond after eating

Comparative Analysis of Postprandial Effects in Healthy and Obese Individuals

Not applicable Interventional University of Hohenheim · NCT06645756

This study tests how healthy people and those with obesity react to a high-fat meal to see if it affects their blood and inflammation differently.

What this trial studies

This study investigates the postprandial effects of a test meal on blood composition and inflammation in healthy individuals versus those with obesity. It focuses on how high-fat diets influence leukocyte activation and the release of pro-inflammatory cytokines, particularly in relation to lipopolysaccharides (LPS). By analyzing the serum metabolome and immune responses, the study aims to understand the chronic inflammation often seen in obese individuals and its implications for health. Participants will be monitored after consuming a test meal to assess these effects.

Who should consider this trial

Good fit: Ideal candidates include adults aged 25 and older with a BMI between 20-25 kg/m2 or 30-40 kg/m2 who can provide informed consent.

Not a fit: Patients with conditions such as diabetes, cardiovascular diseases, or those taking certain medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into managing postprandial inflammation in obese individuals, potentially improving their overall health outcomes.

How similar studies have performed: While the specific approach of this study may be novel, previous studies have indicated that understanding postprandial responses can lead to significant insights in obesity and inflammation.
