The Claim

In young men with obesity, high-intensity interval running leads to a significantly higher rate of lipid oxidation during the 30-minute post-exercise recovery period (1.01 ± 0.43 mg/kg/min) compared to isocaloric moderate-intensity continuous running (0.76 ± 0.46 mg/kg/min), indicating an acute enhancement of fat metabolism after exercise despite equivalent energy expenditure during the activity.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

When young guys with obesity do intense burst running, their bodies burn more fat in the half-hour after the workout than when they jog steadily — even if both workouts burn the same number of calories.

See the scientific wording

In young men with obesity, high-intensity interval running increases the rate of lipid oxidation during the 30-minute recovery period to 1.01 ± 0.43 mg/kg/min, which is significantly higher than the 0.76 ± 0.46 mg/kg/min observed after isocaloric moderate-intensity continuous running, indicating that HIIT acutely enhances fat-burning metabolism post-exercise despite similar total calorie expenditure during the workout.

  1. Study: Acute interval running induces greater excess post-exercise oxygen consumption and lipid oxidation than isocaloric continuous running in men with obesity

    The study found that short bursts of intense running burn more fat after the workout than steady, moderate running—even when both burn the same number of calories during exercise.
