Best way to Burn fat from jogging
This is one of those controversal theories, each person seems to have their own ideas.
The way I see it is thus:
You lose weight as a result of calories burned vs calories taken in. If you exercise at a high intensity (higher then the one suggested for fat burning) your going to burn that many more calories. There are also theories on working out at such a highly intense pace boosting your blood flow for far longer, boosting your heart rate that bit more as your muscles will have been pushed that bit harder, the circulation required to use them will be that bit more. So you burn calories after your workout for that bit longer. This results in a higher calorie burn when your done exercising too.
If your burning more calories running fast then slow, it would follow that your going to lose more weight.
HIIT is something many people do to lose more weight then otherwise. Its used as its highly intense, the body is apparently burning more calories at rest following HIIT then if you were exercising at an average rate for longer. Its also said to reduce appetite too which I cannot comment on (I have not yet managed to get to HIIT standard!) but its another side to exercise: many people will eat more as a result of working out, many assume they burn more then they actually do or disregard the fact that the body becomes used to certain forms of exercise and stops burning as many calories to do so ot trusts machines such as the treadmill which are highly inflated and at best, something to include as a dinner party joke.
The thing I don't get/trust/believe about the slower running = more body fat burned is that if that were so, why do people who do no forms of intense exercise have high body fat? theres a well known thing as skinny-fat where people who do little or no forms of intense exercise (they walk and thats about it) have high body fat around their organs. I can't help thinking that the slow running idea stems from people trying to feel better about taking a more laid back approach to exercise. Yes I agree any exercise is better then none, but theres no reason to boost it up for more then it actually is. I don't buy it.
Like I say, each to their own!
You can probably get as many opinions on this subject as there are fitness 'experts'. Short bursts of high intensity exercise tend to elevate testosterone and HGH levels, which tends to increase fat burning. Extended duration, low intensity exercise (extended duration exercise must by definition be low intensity, because you can not keep up high intensity for more than a short duration) tends to increase the hormone cortisol, which signals the body to store energy in the form of fat. One theory is that this is a reaction of the body when it expects you will call on it to do another extended duration low intensity exercise session soon and it needs to store up energy to fuel that next 'expected' energy requirement. A complicating factor is that intensity level and duration vary greatly from individual to individual and within the same individual depending on age and conditioning level. So what is high intensity or long duration for one person may not be for another.

I've heard different opinions too. It makes sense that interval type workouts could help kick your metabolism in gear but I've also been told that should not do them for every workout. Not sure why. Not sure why, anyone know? If you jog on a treadmill another option is to alternate between elevation levels. Going from flat to incline mimics hills and makes your body work harder at the same speed.
I would imagine its because your body could get used to them or you could get bored and lose motivation. Its also a good idea to keep things as varied as possible for the best possible fitness. It depends on how many days you exercise, what your aims are and if you do other forms of exercise. Doing the same of anything day in day out could be dull very quickly but in terms of what you can do, just like you can go running in the park every time you exercise if thats what you chose to do, interval training is no different as far as I can see.
