You and I have similar goals and weights right now, I'm set for less exercise than you are as I'm easing back into things (It's currently 670 a week), but my range is 1300 - 1650. When I add in an hour of exercise four times a week, that'll go up to around 1400-1700. 1200 is *definitely* too little for you. 1500 may be okay, as that's still in your range, but you may find yourself happier and still lose weight eating a bit more.
2 lbs a week is likely not going to be very attainable for you for long; while it's easy to do when you're over 200 lbs, you're not fat enough to lose that fast. :) You might be able to pull it off right now, but it will quickly become nearly impossible for you! I think a safer, healthier target would be 1-1.5 a week. You can safely attempt to lose about 3% of your weight loss goal per week. For you, that's 1.23 lbs. Even 1.5 would be pushing it! And as you get smaller, it will slow down more. Even if you're going for the 10% rule, you're looking at 1.8 lbs per week, and that will drop as you lose weight.
My advice would be adjust your weight loss goal to 1 lb per week, and update your fitness goals to reflect the amount of exercise you're doing. Exercising more won't make it come off faster. You need to set yourself up on an exercise program you can sustain long-term, because just working out more is only going to burn you out faster. I know, I've hit the overtraining snag myself in the past!
This isn't the Biggest Loser. Those people lose that much weight because they're on constant medical supervision, work out 6-8 hours a day, and have personal chefs and constant harassment to motivate them to lose weight. Those kinds of weight losses simply aren't typical nor achievable for most of us, because the rest of us have day jobs and lives to attend to, and do not have limitless funds to spend on weight loss. Not to mention, it's not advisable; trying to lose that much that fast is going to put you at all kinds of health risks, and we won't talk about the saggy skin. ;)
I'd also recommend getting a heart rate monitor... I assume your machine is telling you how many calories you're burning? If so, those things can be off by as much as 30%... a more reasonable estimate for 30-45 minutes on an elliptical would be 300-400. You may be overestimating.

Writer, mother, wife, and breadwinner. I love to run, but running doesn't love me, so I'm switching to my low-impact bike.
