Losing at 1200 cals??

I'm losing about a pound a week -- some weeks it's more, some less, but that's the average. MFP set my target at 1,200, but I increase it with exercise, and I eat most of the calories added for the exercise (at least half and sometimes as much as all). So I'm usually eating between 1,300-1,500 calories a day.
I also drink at or above 64 oz a day and try to eat more fiber than MFP recommends. I'm doing light aerobics (sometimes just walking or yoga) and light weights (will probably work my way up some more). Following the MFP guidelines seems to work for me.
Almost everyone I've seen post about problems with plateaus, hair loss, etc., has either not tracked consistently or has eaten under the recommended amounts. So I'd suggest you not go below the 1,200.

1250 cal per day, 12.2 lb weight loss in the last 12 weeks.

That's pretty much what's happening to me, averaging a pound a week so far on about 1200 cals, plus I eat back most of my exercise burn off. But then I increase on the weekends to around 1400 cals - because I don't want to be a slave to a diet.

its working for me, slow but sure. Some days I do more but most days I stick to 1200

1200 worked for me for about 5-6 months and then I plateaued for weeks. I raised my calories to over 1500 and stayed the same for another 3 weeks and then started losing again. I also increased protein. I don't care if it's slow, I am *so* much happier eating a little more! It looks like most of the people 1200 is working for haven't been doing it very long...

I started doing 1200 calories a day in late March of 2011 and as of today September 2nd 2012 I am 204 pounds lighter. It has worked for me but I think my body has gotten use to it and I am struggling to lose a pound.
