Surprising Findings
HIIT increased fat-burning percentage by nearly 8 percentage points post-exercise, despite burning the same calories during the workout.
Most people assume 'fat-burning zone' workouts (low intensity) burn more fat, but this study shows intense exercise actually shifts the body to use more fat *afterward*.
Practical Takeaways
Try a 3-minute hard run followed by 2 minutes of walking, repeated 5–6 times, to maximize post-workout calorie and fat burn.

When young guys with obesity do intense burst running, their bodies burn a bigger share of fat in the hours after the workout compared to when they do steady, moderate jogging—even if both workouts burn the same total calories.
When young guys with obesity do a tough workout with short bursts of fast running, their bodies burn more extra calories after the workout than if they jog steadily for the same total energy cost.
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.
For young guys with obesity, doing short bursts of intense running burns 300 calories faster than jogging steadily — about 8 minutes less effort for the same result.
Doing intense bursts of exercise with rest in between can keep your body burning more calories for up to a whole day after your workout.
