What did you base your goal weight on?

I reached my goal by determining what size I wanted to be....that's a 12 or 14.  I'm comfortably in 14's now and want to lose about 10 more lbs and hit the 12's ... I hope.  That would put me at about 190lbs, I started at 325.  I'm 5'2 and love, love, love my curves

I just wanted my BMI to be normal.
