Well, a few things are going on. First of all, the muscles that you use, including your heart and lungs, are burning calories at a higher rate than normal to put out that kind of work, as compared to having a low activity level. It doesn't stop there though, after you are finished your heart rate stays elevated for awhile and the recovery process will also continue to burn more calories than normal. If you keep this up for long enough, your body will increase its metabolic rate, which is basically the amount of energy that your body uses up to maintain itself, so you're constantly burning more calories than before you started exercising.

So what this extra calorie burning means is that when your body uses up what is can from your blood stream, such as the carb stores in your liver, it switches energy sources and starts pulling energy from fat, assuming you are eating less than what you're actually burning. This is where true weight loss comes from.

I'm assuming that this is what you were asking, but maybe not?

To burn calories from fat, you should train in the fat burning zone at 60-70% of your maximum heart rate.

I use a heart rate monitor when doing my cardio. Otherwise, I don't really know how hard I'm working.

calories and fat are really sources of energy... they are the fuel our body uses... so we need to eat a certain amount of calories (and fat) to provide enough fuel to keep our body maintained at whatever level we want.

When we want to lose weight, you can either eat fewer calories or burn more than you take in, or do both, to force your body to use the calories and fats stored in our bodies already - instead of just the ones from the food we eat.

To burn calories from fat, you should train in the fat burning zone at 60-70% of your maximum heart rate.

You can go above that though and still burn from fat, you'll just also burn more from your carb stores and such, and it actually ends up burning more fat in the long run due to raising your metabolism. The "fat burning zone" is more or less a myth anymore, because too many people think that they can't go beyond the upper threshold of this zone if they want to burn fat. That's just not true.

I usually use the pain threshold to judge how hard I'm working. I need a HRM.

To burn FAT, you need to do CARDIO (walking, jogging etc. and reach about 60-70% of your maximum heart rate. For starter you should try 30 minutes of cardio at least three times a week and gradually add more to your routine.

I started walking around town 4 nights a week about a year ago. Now I work out 6 days a week ... I do about 45 minutes of cardio and train a different muscle group each night. You will definately see an improvement in your overall indurance.

Remember though all this mean nothing unless you eat properly as well.

Im down 77lbs from 250... 44% Body Fat to 26%.
Exercise is key!!!!

Not only that with exercise you will LOSE INCHES which is just as important as lbs.

GOOD LUCK to YOU!

I agree that one can reap more benefits from working at higher intensity. But I still think that the "fat burning zone" is relevant for beginners...being the lower limit that they should be working out. As their fitness level improves, they can exercise at higher intensity.

Personally, I prefer to work out at high intensity to benefit from the 'after burn' effect and to challenge my fitness condition. I normally do my cardio at more than 70-75% of my maximum heart rate.
