NCT ID NCT04385615
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study was designed to test whether a fasting-mimicking diet (FMD) can activate beige/brown adipose tissue—a type of fat that burns calories—in people with overweight. Researchers planned to measure changes using PET scans, thermal imaging, and blood tests. However, the study was withdrawn before enrolling any participants, so no results are available.
