The Wikipedia definition of EPOC : “Excess post-exercise oxygen consumption (EPOC) is a measurably increased rate of oxygen intake following strenuous activity.”
Anaerobic exercise increases EPOC more than aerobic exercise does. Resistance exercise (strength training) is primarily anaerobic. Circuit resistance training produces the largest EPOC response.
From this article, Impact of exercise intensity on body fatness and skeletal muscle metabolism, this quote:
“The metabolic adaptations taking place in the skeletal muscle in response to the HIIT program appear to favor the process of lipid oxidation”.
And this:
“Despite its lower energy cost, the High Intensity Interval Training (HIIT) program induced a 
more pronounced reduction in subcutaneous adiposity compared with the ET program. When corrected for the energy cost of training, the decrease in the sum of six subcutaneous skinfolds induced by the HIIT program was ninefold greater than by the endurance training (ET) program”
If you want to get the most for your minimal free time or if you hate to exercise HIIT will burn more calories for the time spent. Calories are burned four ways with this workout:
We burn calories four ways. One of the ways is the burning of additional calories after the exercise session is over.
From this article Facts on Foods That Speed Up Metabolism:
· The amount of calories you eat, your genes and the amount of calories that you burn while eating and exercising determine your metabolism.
· The body breaks down carbohydrates, then fats and finally proteins.
· The food that you eat makes up 5 to 10 percent of your metabolic rate.
You’ve seen them performed in aerobics classes. You raise your leg out from your side while standing, while on all fours, or while lying on your side. This is done repeated with one leg and then the other. All the different permutations of sets of legs lifts are performed at least once and som
etimes later in the class the raises are repeated.
“A study at Penn State University found that when participants ate soup before their entree, they reduced their overall calorie intake from the meal by 20 percent compared to those who took an entree with no soup beforehand,”
