old techniques are mixed with exercises . so you begin exercise
with complete empty stomach . never do that . number two the
stomach should not either be full. both harm you .
the myth is that if you start empty stomach , your body will dilute
the fat and take energy by doing that.
the primary energy source in case of empty stomach is not the fat
but protein which is a better source for immediate requirements.
so think again.
you can begin with few nuts if you dont feel like taking anything.
