Depending of the amount of weight lost, you could take in on the sides. If you do the back, it will look funny on the "cheeks" Just a tuck on each side should do. Take them to a seamstress, and try them on there, and they will take car of it. If you lost alot of weight, and need to do the whole side seams, I say just go buy new jeans. Think of it as a reward for all your hard work!
