First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether intermittent fasting—fasting for 16 hours and eating within an 8-hour window—can help healthy adults lose body fat and feel better. Researchers will measure body fat percentage and visceral fat, and track quality of life. The study involves 70 healthy participants and compares fasting to normal eating over four weeks.
