Are you OVERWEIGHT?? ummm... NO!

Underweight, quite possibly.... I forget how tall I was and how much i weighted at your age.. But I'm 5'2-3 now, and I weight 120..

I don't think you are under by too much, as long as you don't look too skelliton like, then you have nothing to worry about.

If you eat well and stay active, and that's how much you weigh, then you are just a small boned person who will probably never be overweight.

But if you don't eat and try to be skinny, then I'd assume you look bony and unhealthy.

It sounds like you can definitely stand to gain a few pounds before you'd ever become overweight. It's good that you have muscle mass but no one can give you a proper answer on here though.

A lot of people like to play doctor, but they aren't. If you're concerned, talk to your parent or guardian. I know it can be a little uncomfortable sometimes, but you're way more likely to get a better informed answer from them then from some of the clowns on the internet Lol

You're underweight like 10 pounds underweight especially since you have muscle. Muscle weighs more than weight.

No, you are just skinny. there is nothing wrong with that. I'm skinny to, but not 91 lbs. You should be glad for your size. Many people wish that they could be skinny as you.

fyi i know a 15 year old guy that weighs less than that and hes a wrestler im sure youll be fine, im not exxagerating either he weighs 80 pounds

Yes, your BMI is 16.5, where as the minimum BMI to be in the healthy range is 18.5. It's not major, but a little under what you should be.

It isn't about weight it is about health. If your doctor did not get concerned during your physical you are perfectly fine. I truly love to see active teens.

HAH you sound like a frnd of mine....well yea, ur skinny. deff not overweight. a few more pounds on you wudn't hurt. =)

Because of your height and your age, you can get away with being that thin, but be cautious in the future.

You're normal, maybe underweight.
