Numbers all wrong, stuck! Maybe this will fix it.

I posted last week that i was stuck and did not know why or what to do cause I was doing everything that the site said to do. In fact I did not have any trouble dropping the weight until I started exercising everyday! I could not believe that I would just get stuck like that after exercising more! I was even eating my cals back and everything. Well I just read an article in Woman's Day about your metabolism. It gave a little chart at the bottom to help you figure out what your metabolism burns every day before exercise and all. It says for Sedentary peeps multiply your weight by 12, Moderately active-x 14-15, and very active-x 16-18. I am some where close to the border between sedentary and active, depending on how much I exercise during any given week, so I went with sedentary to be safe. I am 198 right now so that equals 2376. Now, MFP says if you want to lose 1 lb/week to short yourself 500 cals a day and for 2 lbs a week short yourself 1000 a day. If I subtract 1000 that leaves me 1376 that I should be eating everyday, not counting my exercise cals...so why then, did MFP have me eating only 1200 a day? There is something wrong with their calculations. According to this, I should not have to get down to 1200 until I am at 190 (if I want to keep losing 2 lbs a week) So I WAS right in that the reason that I stopped losing is probably because I WAS eating to little calories a day to begin with before exercising (which WILL slow your metabolism and stop your weight loss). Even by eating my exercise cals back I still was eating to little cause my base what set to low. SO I played with the settings until it gave me a daily calorie limit of a little over 1300 and i will stick to that for a few weeks and see if my weight loss does not start up again and get back on track...everyone that is having this problem should check in to this. You can do some more research and see if you come up with the same formula that was given here but it makes enough sense to me that Im just gonna go with it and see if it helps. I had tried to up my cals a week or so ago but I felt bad about it thinking I was supposed to be only eating the 1200 so now maybe I can do it and feel like I am doing the right thing and finally start getting somewhere again! I will let you all know what my results are!
