BMR

Be smart. Figure out your TDEE as well, and then eat between your TDEE and your BMR. Question: is that really your BMR, or did you add exercise regimen into the MFP calculation? If you added exercise as well, then that's actually your TDEE, not your BMR.

MyFitnessPal pretty much puts *everyone* on the 1200 calorie diet, but if your BMR is 1629, don't eat less than that.

mfp tells me 1200 calories per day, however my bmr is 1629, which am I supposed to follow?

Have you read the "In Place of a Road Map" post? The short version is "Eat your BMR and eat back a good portion or most of your exercise calories."

MFP gave you a number based upon the number of pounds you want to lose each week...... that doesn't mean that, that number of pounds is appropriate.

Figure out where you are (below) and set a new goal per week in MFP. That new number should be higher than 1200 (too low for most). Remember MFP will want you to eat exercise calories back, that's really imporant especially as you get closer to goal. Too big a calorie deficit results in muscle loss.
