Why is this happening?

i dont eat much, because im trying to lose weight. usually, i eat 0-1 meals a day. im not anorexic, because i do eat just not a lot. but i read that anorexic symptoms usually include growing fine hairs?? and i have some hair on my stomache and its weird. so im jw if this is bcause of my eating habbits or what???
