While one might think that weight loss is simple math, the fact is that our bodies don't always burn calories at the predicted weight. You can track your intake pretty closely, but the fact is that "calories burned" is just a guess. These types of calculations cannot take into account your body composition (lean vs. fat), which affects your burn rate. It also cannot know your individual metabolism. Also, I have found that some of the fitday estimates for certain activities are wildly different from other web sites.
While you may feel disappointed that you haven't lost as much as the fitday calculations would have predicted, the fact is you ARE losing. Your age, weight, dieting history, medications, medical conditions etc., all play a part in determining a reasonable calorie level. Even so, a loss is a loss, and one of the most self-defeating things you can do is set timetables for when you want to weigh a certain amount. There are things you can do to optimize your losses, but if you get in too big a hurry you can wind up shooting yourself in the foot one way or another. If you cut your calories too low, you can plateau early and have no place to go from there, for example.
Why don't you go to
www.jimkaras.net and use the Harris-Benedict calculator. This will give you an idea of a calorie level to START with -- your individual needs may vary up or down, but it's a place to start.
Finally, try to be content with slower losses. I am just about your weight and I average 1/2 pound per week now. As long as I continue to lose overall, I'm happy. I can't be anything else, because I can't change how my body is dealing with this.
