It also has to do with what you eat (eg protein harder to store as fat than sugar) and how much exercise you do. I am aiming for between 1800-2000 cals a day, but run 5 days a week and don't eat back exercise calories. I also will stop if I'm full, so today I ate 1450, because that satisfied me. Tomorrow I'll probably be hungrier because I ran today and running tends to suppress my appetite.
I don't pay any attention to calorie calculators. If I stop losing weight, I'll cut cals or up the exercise, but I like my food too much.
