Personally, at your beginning level, I wouldn't even bother taking it.
Build a good base with your weight training, eat right, take fish oils, a good multi-vitamin, and supplement with variety of good protein sources. Later, when you're further along, you could consider it. But no, there isn't any direct weight loss effect from creatine. Depending on the type of creatine, you may retain more water weight than normal. It does help you to some degree in training and recovery, but again, for a beginner, I would stick with the basics.
