Yes, like Bunny said, you have to go in and reset your goal to be your current weight and with about a year out. I'm in maintenance now and my range (obviously yours will be different) is 1440-1790. I've found in order to maintain, I need to eat a little bit above that top number to stay where I'm at, on an average. I found when I stayed in the middle of that range, on an average, I lost weight.
It also is a bit of an experiment to figure out where you need to be. I lost 11 more pounds before I figured out that the range I was given was too low. It was a scary thought to eat more than the range, but it's been working out pretty well now, I've been maintaining here for about 4 months.
You also might want to come join the Maintainers Spark Team. It's a very very active team with lots of great resources for maintainers. teams.sparkpeople.com/maintaining
