BMR cals or MFP recommended cals?

Hi all.
Tonight i have been introduced to the BMR.
My BMR is 1, 512.
Myfitnesspal has told me i should be aiming for 1,200 cals.
Which one should i listen to?
And why are they both different?
yesterday i went over and consumed 1,310 cals is that enough or too much?
Confused!

to lose weight you need a defit from your maintenance calories. (TDEE)

What are your maintenance calories?

Your BMR is the amount of calories your body needs to function. Your TDEE (Total Daily Energy Expenditure) is how many calories your body needs to function plus all of your daily activities such as work, exercise, sleep, play, housework, etc.

Did you choose that you wanted to lose 2 pounds per week when you registered here? If so, that's probably why mfp told you to eat 1200 calories. You would be better off changing it to 1 pound or 1/2 pound per week, especially since you only want to lose 30 lbs. If you exercise make sure you log those workouts on here and eat the calories that you burned.

To eat at a deficit and lose weight you'll want to subtract 20% from your TDEE. Maybe even 15% because you don't much to lose. You might find that changing your goal to 1/2 pound or 1 pound here on mfp will give you about the same amount of calories.
