Your total energy expenditure will be much greater using HIT cardio simply Flat Belly Overnight Reviews because you're exerting more effort. Relatively speaking, HIT will use a lower percentage of fat versus carbohydrates, however, in ABSOLUTE terms and because total caloric expenditure has increased, so too has your net fat expenditure. As a result, your net fat utilization during exercise is actually higher during HIT!
Thanks to a study by LaForge and Kosich (1995) it was demonstrated that exercising at a higher intensity for a given time proved to burn more fat than at a lower intensity.
The fact is, you do burn more calories during a long duration low intensity cardio session compared to a short duration high intensity cardio session. But the real advantage of high intensity training is the post workout 'afterburn.' Simply put, when you exercise intensely for short periods of time you continue to burn more calories AFTER the workout has finished.
This residual calorie burning effect can last from 24 to 48 hours - and in exercise science it is called E.P.O.C which stands for "Excess Post- exercise Oxygen Consumption."
What this means is that your metabolism is raised for a much longer period than with a traditional LIT or "fat burning zone" workout.
Something Flat Belly Overnight Trick extraordinary happens when you train using high intensity cardio. A study at Laval University in Quebec published in a journal called 'Metabolism' back in 1994, showed that high intensity exercise burned off significantly more body fat than steady state endurance exercise. In this case we're not talking about calories burned during exercise, or whether they came from fat or carbohydrate, we're talking about actual fat that disappeared from actual bodies.
The research concluded that: Every calorie you burn during high intensity exercise strips off 9 times more body fat than a calorie burned during low intensity cardio!
