I'm 5'11 tall and weigh 147 pounds, am I underweight?

I'm always weighing and measuring myself, its compulsive.
Recently went to my doctor and my measurements are
40-30-37. He said I'm showing symptoms of developing an eating disorder.
I said women get that and he laughed. He said its on the rise among men.
I'm confused coz I dont starve myself i just dont like eating unhealthy fatty foods and i always excercise.
Please help me

Are you a man or a woman? If you are a man, yeah, you're underweight. If you are a woman, you sound about right as long as you're bones aren't poking through
