You will not know until you try. Just take that 2019 and subtract only what you will not eat. Say, you're going to cut the 500 cals for a pound a week. Keep doing your activities. If you're hungry come back and tell us.
I'm going to be pretty blunt for a moment here. When people say that they are eating 1400 cals and are not losing weight ... they're doing something wrong (in general, barring illness or disorder or being 4'6") Probably not accurately recording their food intake and fooling themselves about how active they are.
There ... I'm done with that rant.
Just record your intake. Keep it at about 1500 cals and continue on yur merry way with the exercise you have chosen. You will, over time, lose weight.
