Lightly Active or Active?

Options
I currently work at a desk job and university part time. However, I workout six days a week for 45-60 minutes with a HR of 145-165. Does this make me lightly active or active?

Last summer I "accidentally" left my activity level on "sedentary" and lost about 25lbs. Working out twice day for 4-5 days a week. Now that I've lost the weight and am still working out almost every day, 1400-1600 calories still leaves me feeling hungry.

Any suggestions on how to lose that last 5-10lbs?
