While exercising our muscles burn both fat and glucose (carbohydrates in the blood) in different proportions. Depending on how an individual exercises muscle can burn fat in a larger proportion to glucose.
When activity is light and easy we tend to burn a much higher percentage of fat. Fat is a slow burning fuel that requires oxygen so if oxygen is delivered to muscle cells in sufficient quantities the cells can easily burn fat for most of its energy requirement. A potential problem for weight loss is lighter exercise burns fewer total calories.
If an individual increases their effort by performing a more intense exercise they WILL burn more calories however, because oxygen cannot always be delivered to the hard-working cells in sufficient quantities, cells are forced to burn more carbohydrates in order to keep up with increasing demand. If the level of exertion continues to increase then glucose eventually becomes the predominant energy source for muscles as this quick-burning fuel does not require oxygen.
It means to burn fat directly we should exercise at a lower level of effort and for longer duration. However some people just don't have the time to exercise for longer periods. The only way to burn fat quickly is to increase the metabolism through anaerobic exercise so we burn the fat indirectly.

This is not even from a BB point of view. but it does coincide with what many of the bros here preach. no more running on the treadmill...walk on an incline. since that comes as a shock to many people when they hear it for the first time, here it is from another source. doing it in the morning on an empty stomach to minimze the glycogen store will maximize results.
Edit: shoot, this is in the wrong forum...
