I think the answer is pretty complex. At 1250 you probably aren't entering any kind of starvation mode or anything... but it's much too low for your weight -- it won't be easy to get in good nutrition for example. The more we weigh, the more calories we need to do everything! So 1250 might be a good number for some who weighs under 200 pounds, but you should be able to eat quite a bit more AND still lose at a steady pace,
And you will need to be patient, even if you up the calories (which would probably be a good idea at your weight). Weight loss isn't linear. You can do the same thing from week to week and lose sometimes, stay the same sometimes, or even gain. That's because the scale weighs all of us, and lots of us fluctuate, especially with regard to water weight.
So, don't starve yourself, be consistent, eat as healthy as you can, get in some exercise, and be patient!!!
