NCT ID NCT07515547

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study looks at 150 adults with obesity to see if there are differences in fat, muscle, and metabolism between those who were obese as children and those who became obese as adults. Participants will provide tissue samples, blood, and urine, and undergo a weight loss program. The goal is to understand how the timing of obesity affects the body's biology.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
weight loss program (diet and exercise)
What this could lead to
If successful, this could help tailor weight loss treatments based on when a person first became obese.
What could go wrong
This is an early observational study with only 150 participants, so results may not apply to everyone. The weight loss program may not work for all, and biopsies carry minor risks like bruising or infection.
