Is 900 calories a day healthy..even if im stuffed?

i forget how much an average person is supposed to eat in a day. i think in kids its like 2000, and adults its like 1600...... or it might be 1200 and 1000 but im not sure... u r pretty short for ur age, so im not sure if its unhealthy to eat so little... if ur not hungry, than u cant eat more, but if ur concerned, ask a doctor
