FitDay is giving me a target over 2000, and the previous software I was using was at 1150. These are all based on stats of female, 48, 5'4", currently 257 lb.
For the past 45 days I have been near 1300 cal per day and lost 14lb over four weeks. Over the last two weeks I've regained 2 lb with no change in diet or exercise. The voices in my head are going nuts. The sensible voice says to ride it out while the more hysterical voices are trying to outshout each other to either raise or lower the target.
Does anyone have a reliable way to calculate this?

Since you already have a 4 week baseline then finding your calorie targets is just a matter of a little math. I you lost 14 lbs. in 4 weeks (and a pound is approximately equivalent to 3500 calories) then you burned 49000 calories (14 X 3500 = 49000) more than you consumed. Thats an average deficit of 12,250 calories per week (49000/4=12250) or 1750 calories per day. Working backwards that means that if you ate 1300 calories per day then you burned a total of 3050 calories per day. That 3050 is a total of your Base Metabolic Rate (BMR) and your Activities. If your BMR is around 2000 (if you have filled out all your information you can see what Fitday is calculating by just clicking on your Activity Tab and seeing the number) and your exercise/Activities would account for the remainder.
1750/day is a fairly large deficit (although not unreasonable with your stats) but everyones body reacts differently and your may be trying to slow down your metabolism because it thinks it is starving due to the large deficit. Some time just increasing your calories by 200500 is enough get your body back in line again. The balance of your FAT, PROTEIN, CARBOHYDRATES could also effect how you lose. I lose better when my protein is about 30% of my calories (again everyone is different so you may need to experiment some to find what works best for you).
If you set up a Weight Goal in Fitday it will calculate the deficit you need daily to attain the goal. The deficit is the important number. You can eat as many calories as you wish as long as you are willing to exercise enough to maintain the deficit. The more active you are the more you can eat. Let us know if tyou have more questions or need clarification.
