Is it just me? Or anorexia?

So I'm not fat- But I want to tone my muscle.. My bmi is 23.7 and I'm 5'6"/5'5" and I'm skinny-fat with wide hips.. All I'd like to do is get really toned (abs and arms) like mikasa from attack on titan! XD I don't starve myself.. ever. Or make myself sick. Does it sound like I do?
