Did 30DS help you lose back fat?

Scandinavia

I have an event coming up at the end of the month, and am currently on day 3 of the shred. My dress (side zipper) zips up everywhere but the area around where I store my fat - the side-back-fat roll. There's about an inch left there until I can zip it up.
Will the shred be able to (at least) reduce it?
