Can we predict weight loss slowdown? new study seeks biomarkers
NCT ID NCT05139420
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study aims to find biomarkers that identify people at risk of a disproportionate drop in resting metabolic rate during and after weight loss. Sixty participants with obesity will follow a 6-month meal replacement program with lifestyle advice. Their resting metabolic rate and hormone levels will be measured over 18 months to understand why some people's metabolism adapts more than others.
