First seen Jun 27, 2026 · Last updated Jul 31, 2026 · Updated 2 times
Summary
This study tested whether taking tadalafil (Cialis) daily for 12 weeks can change how fat tissue works in obese adults. Researchers used MRI scans and fat samples to measure fat metabolism and gene activity. The goal was to understand if the drug could make fat behave more like calorie-burning brown fat, not to cause weight loss directly.
