Abstract in brief

The study used stable isotope tracers and indirect calorimetry to analyze how fat and glucose metabolism are controlled during different exercise intensities and durations.
At lower exercise intensities (25% of VO2max), fat breakdown was maximized, while glucose utilization increased with higher intensities (65%-85% of VO2max).
Recovery from high-intensity exercise saw a brief drop in lipolysis but an increase in fatty acid release from triglycerides, showing that carbohydrate metabolism responds directly to exercise intensity while fat metabolism is regulated more complexly.

Carb metabolism directly affects fat oxidation. High carb intake increases insulin, which suppresses lipolysis (fat breakdown).
