I agree, everyone is different. Also when you start setting expectations, murphy's law seems to come around and you don't meet your goal and you get discouraged. I did loose 19 lbs in the first month (not sure how much in 6 weeks but it was more than 20), however, I seemed to loose REALLY fast in the beginning. Not sure if you'll be like that too. One thing is for sure, you WILL loose in the first 6 weeks and that's progress.
