I never feel hungry anymore?

ive been eating clean, running and trying to build a little muscle now for the past few months (previously stuck in a restrict/binge nightmare). up until recently id constantly be hungry. seriously my stomach would always demand food. i was having almost 1600cal some days and still be starving. now, i find it hard to eat, like im struggling to eat 1200. i know if i dont my metabolism will slow down but im buring like 400-500 calories during workouts too! like, i really want to eat but seriously i dont need to and id be fine. should i "force" myself to eat still? or just dont eat if im not hungry? (which is never) the hungriest ill get is just a little tiny bit. i feel like eating is pointless. im also trying to hit my macros everyday which is difficult when i dont even want food....... adivce? if im under 1200 should i force myself if im not hungry at all?!
