I just got in from my run and was thinking about what could have happened with your calorie range...because you lost such a large amount of weight in a very short time frame, you have lessened the amount of weight to lose but only with a one week loss in that time frame. So instead of having to say lose 30 pounds in three months, you now only have to lose 20.5 pounds in 2 months and 3 weeks time. Does that make sense?
Remember your goal is to lose 1-2 pounds per week. While I know that isn't as exciting as 9 pounds, doing slowly ensures that you will lose a larger percentage of fat while preserving a larger percentage of metabolically active tissue (muscle), along with bone, connective and organ tissue.
Weight loss is not so much a goal as is it a result of all the goals to get you to that points. Things like eating more fruits and veggies, drinking water in place of soda, exercise 30-60 minutes 5 times a week, etc. In other words your goal is to change your lifestyle, not just lose the weight as quick as you can only to go back to the way you used to live.
I hope this helps!
