Will pilates help me lose weight?

So I'm 17 and a little chubby, I'm not fat or anything, I have a little flab on my stomach and bigger thighs but I'm not really fat or anything. I heard pilots really helps flatten your stomach is it true? Because I've tried it and really felt the burn but I'm worried it will only build the muscle and not burn the fat, which would basically do no good. Suggestions?
