I'm never hungry anymore!

My goal calorie total is 1200 a day, but I'm never able to reach that without practically shoving food down my throat. I hardly ever have an appetite anymore, even though I know I HAVE to eat that many calories. Should I only eat when I'm hungry, or continue trying to reach the caloric goal? (I also burn 350-500 calories a day, which would bring down my deficit even more)
