how long will it take me to lose my belly fat?

i have a healthy weight figure, but my belly is a little bit fat.
i run for 10 minutes every week day & do this exercise video every week day http://www.youtube.com/watch?v=2htZIjhuDaM
i have been doing this for 2 weeks now & i still have a bit of a fat belly.
i can see my abs underneath the fat though.
how long will it take me to lose my belly fat? & what can i do to make the process faster?
