First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether limiting food intake to an 8-hour daily window (time-restricted eating) works as well as reducing daily calories by 15% for weight loss. 115 obese adults with insulin resistance participated for 12 weeks. Researchers measured changes in weight, body fat, and visceral fat to see if the fasting approach is a practical alternative.
