well, katy did say her number was based on the 10 calories per pound formula for maintenance. so op's number comparing in that fashion would be 2200 for maintaining, 1700ish for losing a pound a week.
Are most of your carbs low GI? Are you sensitive to carbs? Are you apple shaped? YOu might want to try swapping some of your carbs for lower GI ones, or reducing them in favor of more protein. Or you could try upping your calories to about 1700 a day. If neither of those work, you will either have to restirct carbs even lower, or cut calories lower. But I would personally try the first 2 options before the second 2. Don't worry: you will find your formula!
