10-Hour Time-Restricted Eating and Heart Health Risks in Firefighters Working 24-Hour Shifts: A Feasibility Trial

AI simplified

Abstract

This study involves 150 firefighters participating in a trial to assess the impact of a 10-hour (TRE) regimen on health parameters associated with cardiometabolic disease.

  • Chronic circadian rhythm disruption in firefighters is linked to increased risk of cardiometabolic disease.
  • Preliminary studies suggest that time-restricted eating may help regulate circadian rhythms and reduce disease risk.
  • The intervention group will follow a 10-hour eating window, while the control group will receive standard Mediterranean diet counseling.
  • Health parameters being evaluated include blood glucose levels, body weight, body composition, and various biomarkers related to metabolism and inflammation.
  • Assessments will occur at multiple time points throughout the year, including after a 3-month monitored period and subsequent follow-ups.
