High vs Low-Intensity Exercise - which is better for fat-burning?

Although research shows that lower intensity exercise uses a larger percentage of fat as fuel compared to higher intensity exercise, low intensity does not burn as many calories.  Consequently, less fat and body weight loss result.  Gradually   increasing the intensity of your exercise will increase your caloric deficit and keep your metabolism elevated even after your workout - adding more calories to your deficit!  Even if you only have 20 minutes - make it count!  Breathing hard and sweating are good indicators of your high intensity exertion.  Remember this - “SHORTER=HARDER”
