Time Restricted Feeding in Male Runners

Completed · Not applicable

Conditions studied: Fasting, Intermittent Fasting, Athletic Performance, Cardiovascular Risk Factor, Resting Energy Expenditure

In brief

This is a cross-over intervention study designed to evaluate how four weeks of time restricted feeding (16 hours fasting and 8 hours feeding), compared to four weeks of a more traditional eating pattern (12 hours fasting and 12 hours feeding), affects resting energy expenditure, subjective and biochemical markers of satiety and hunger, body composition, cardiovascular health, substrate utilization and fitness in male competitive runners.
