Ok, so I'm 23 and need to lose about 160 lbs... Any tips? Will me weight drop fast since I have more to lose? Will I even lose that much?

Well, no one can tell you exactly how you will do; but in general, larger people lose faster up front. My goal was a 150# loss and I have lost 2/3 already. My doc said he thought I would make it to my goal easily by my 1 year surgiversary. We shall see. I hope he is right.
