Is BMI 15.7 unhealthy?

I have a BMI of 15.7. I'm 13 and I'm 5 foot 9 and weigh 106 lb. is this underweight and unhealthy cos apparently it is. I am currently eating very little cos I'm trying to achieve a 6 pack so don't want to consume a lot of calories. I am also running a lot and trying to lose my belly fat. Please tell me if this is unhealthy. And also, if u have any 6 pack tips, that would be greatly appreciated. Tyvm

• Your bmi is considered unweight, but if you don't have any anorexic thoughts (even though you can be overweight and normal to have anorexia) , if not you should be okay. I don't know any 6 pack tips, maybe try sit ups, an crunches.

Just takes healthy food and continue your running practice. You become a healthy civilian in the society who lead the world one day . Stay healthy!
