In the end, they all use the same energy. If you draw from glycogen while exercising intensely, then that glycogen will eventually be replaced by body fat being used up.
This so-called "fat burning zone" is a justification and perhaps a motivator to get folks moving and doing things who are not doing anything at all.
It helps them not be scared of the kind of intense exercise that most of us do regularly. It is propaganda, pure and simple.
And SSP is right. Without a careful food plan, it is all to naught.

Since most of us are limited in the time we can devote to exercise, the rule of thumb is:
If you can't go long, go hard (double and triple entendres intended
)
