eating back my BMR calories?

Take the BMR thing with a grain of salt. It's not so important when you have a ways to go. Just set a level you can live with for awhile.

Trust the MFP number, its pretty accurate...and in a few weeks you'll know by progress how your doing.

I have another app that I downloaded ( my net diary) which tells me that I need to be eating at my BMR level, which is at 1935 or so. It tells me that if I go below that, that its dangerous? My calorie level is set to 1745ish.

I guess I just don't fully understand the whole deficit thing. Is the information that the other app is giving me correct?

No, the "you must eat above BMR" is nonsense. Among other things, you don't know what it is, really -- different calculators give different numbers and they tend to overestimate for people above average body fat (which is most people who need to lose substantial weight). I lost my first big chunk of weight eating below BMR (and my MFP goal, pre exercise, was below BMR until I switched to a different method of calculating calories where you don't eat back exercise).

That said, for most people who are exercising, their reasonable deficit will be above BMR. If MFP gave you 1745 to lose 2 lbs/week, you are expected to add in calories when you exercise which would put you above the estimated BMR, probably.
