BMR and calories out/in with exercise.... not getting the co

Hi!
Ok, I have been with MFP for about six months now, but just recently rejoined (2 weeks ago) due to a month off when I moved to a new city with my family. Anyway, getting back into the swing of weightloss. I have a question about BMR..... What does this have to do with my weight loss?? Should I adjust something of mine?

I currently have my calorie set at 1200 per day.
I exercise and have about 550 (average) calories added to my day.
I usually eat back all of them, making my totals somewhere near 1700 for the day.
My BMR calculator says 1527.
Should I not be eating all my exercise calories back each day so my total equals my BMR? Or am I confusing this concept?

I am losing about a pound a week so far, but have only been back on track for two weeks, so who knows what my body will do.
I need to lose about 25 pounds to be back at a healthy post twin pregnancy weight.
Any advice or help would be much appreciated.
Thank you!

    Your BMR is what you burn if you were is a coma all day. Your maintenance calories are much higher (go to goals and look at calories burned from normal daily activity, that is maintenance) If your maintenance is 1900 and you burn 500 from working out, your maintenance for the day would increase to 2400 (1900+500), so if MFP gave you 1200 (700 cal deficit from the 1900) and you burned 500 and ate all 1700 you would still be at a 700 cal deficit as 1900-1200 = 2400-1700, both give you your goal deficit, in this case 700.

    The way I understand it is this:
    You will burn the BMR (1527 Approx) at rest, without exercising.
    In order to lose weight, you have to burn more than you eat, burning about 3500 cal per lb to lose.
    Thus, they take you down to 1200 consumed. There fore you burn 1527 a day, and only eat 1200, so you are burning 327 (approx) a day for more than you eat.
    If you exercise, (burning 550 cal a day) you would burn 1527 + 550 = 2077 calories a day. So, by eating your exercise calories and you 1200, eating 1750, you still have that deficit needed to burn the "old" calories. And, You're golden. :)

    No BMR is what you would burn in a coma, maintenance cals are higher as you burn more than bmr the moment you wake up and eat, brush your teeth, or just sit there.

    Use this:
    BMR = 370 + (21.6 x LBM)
    Where LBM = [total weight (kg) x (100 - bodyfat %)]/100

    The Katch-McArdle formula is the most accurate calculation. Divide weight by 2.2 to convert to kg.

    So for me:
    5'6"

    LBM- [105 x (100-35]/100= 68.25kg of lean mass or 150 pounds.
    BMR=370+(21.6 x 68.25)= 1844

    Add in a modifier of 1.4 for activity, but don't go higher than that unless you are extremely active at work and in the gym.

    Final maintainence for me= 2580, or 2000 to lose about a pound per week, add in exercise and I'll lose a little more.

    The concept is the same. It's still showing her the deficit. Makin' it easy to understand. That's all, dude. Sorry for "getting it wrong".

    Just pointing out that maintenance and BMR are not the same thing, as I don't want the OP to be confused.
