Thank you to everyone who took the time to respond and help me out. I have actually increased my calorie intake, to about 1400, plus eating all of the calories I am burning during exercise, which means I am eating more like 1900 calories, burning 500 of that off during exercise.
I am happy to say that seems to be working. I have dropped 1.4 lbs in 2 weeks, yay! Part of what I think is also helping is the addition of some strength/weight training into my workout routine.
Thanks again everyone!
