Time-restricted Feeding Improves Basal Fat Oxidation and Body Composition But Not Fat Oxidation During Exercise

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.
