NCT ID NCT07229170
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks back at medical records of 150 adults aged 18-60 who took GLP-1 drugs like semaglutide for weight loss. Researchers want to understand how these drugs change taste perception, food preferences, and eating behaviors. The goal is to learn more about why these medications help people lose weight, not to test a new treatment.
