Weight Supplement that works?

Hi guys. Long story short. Im a big fatty mcfatterton. Ok its not that bad but I do want to get into shape. I am taking Kung-Fu classes at the community center and lifting weights after class. This is done twice a week and will increase to 3 times per week after a month or two. I have also adjusted my diet and I am losing weight. But I would like to maximize my hard work with some kind of work out supplement. Can anyone recommend something? I was thinking of trying Hyrdroxycut. Thanks.
