I lost my first 30 lbs in 1 year -- which is pretty amazing considering I didn't do a single minute of (delibrate) cardio in that entire year. It was all weight training and better eating habits.
I then "took a year off" (whoops) from losing when I moved to the UK, came home having not gained a single pound (thank goodness), and dropped another 19 - 20 lbs in about 8 months -- which got me down to my goal of 139 - 140 lbs last Christmas Eve.
I then convinced myself I was in "maintenance mode" and slowly crawled back up to 150 over the last 9 months or so.
I hope that answers your question without being too confusing.

Also note that I have always lost at a rate of about 1/2 lb a week which is WAY too slow for most people. But it's a rate that works for me, and I'm quite happy with it.
