I want to shed at least 10 pounds?

I'm 5'6 and I weigh 118. I have cellulite on my lower body and I want a flat tummy. I already completely cut back on all junk and I have a balanced meal plan I follow everyday. I only drink water and eat healthy meals. I run and walk everyday and I would like to know how long it'll take to shed 10 pounds. I also have an extremely fast metabolism, if that helps at all.
