Six Weeks of Time-restricted Feeding Improves Basal Fat Oxidation and Body Composition But Not Fat Oxidation During Exercise in Young Males: A Randomized Controlled Trial
In Brief
A clinical study evaluating Intermittent Fasting: Time Restricted Feeding During 6 Weeks for Dietary Exposure. Completed, enrolled 34 participants across 1 site.
Detailed Summary
Time-restricted feeding is one of the IF models with significant advantages beyond other IF models, such as simplicity and flexibility, where individuals limit their eating window to specific hours of the day, with a fasting period of at least 12 hours. Ample evidence in humans suggests that prolonged daily cycles of feeding and fasting when aligned with the circadian rhythm, as in the TRF regimen, can alleviate metabolic diseases. Furthermore, research supports a range of health benefits associated with TRF programs in diverse populations, including improvements in body composition and insulin sensitivity, appetite regulation, and achieving a more balanced hunger sensation. Moreover, adopting a 6-hour eating window followed by an 18-hour fasting period can elicit a metabolic shift from relying on glucose to utilizing ketones for energy, which is associated with extended lifespan and a reduced risk of various diseases including type 2 diabetes and obesity. This study aimed to determine the effect of a 6-week TRF on resting and exercise substrate oxidation and changes in blood markers linked to cardiometabolic health.

Timeline
Interventions
Thirty-one healthy, young males (age: 27.5±6 years, body mass: 76.5±8.4 kg, and maximal oxygen uptake \[V̇O2max\]: 43.9±6.6 mL/kg/min) were randomly assigned to either TRF (n=14) or control group (n=17). TRF group followed an 16:8 intermittent fasting diet program for 6 weeks. Body composition, insulin sensitivity, resting substrate oxidation, and fat oxidation during cycling at 40% V̇O2max were assessed before and after the diet program.
