Is it bad to be 13 and weigh 80 pounds?
Should I lose/gain weight?
depending on your gender and height. If you're a male and relatively tall than it might be good to eat some more. If you're a short male or a female it's probably fine. In any case there is nothing to worry about.
My 11 brother weighs 86 pounds
It's a little underweight but it also depends on you height. You can gain weight if you wish but in a healthy way :)
im 13 and weigh 110
How tall are you?
I'm guessing your short. I'm 15 and weigh 100 plus I'm 5'7. I just have a fast matablism
It depends on your height....
well my 10 year old sister weighs 75 pounds so you should at least be 85 pounds at 13 in my opinion
Depends on you height, if your like 4'9 then your fine. But if your 5'4 then you need to gain some weight:)
wat no. im 13 and thats how much i weigh and im 5'1.(my docter actually thinks im a little under weight) so it is probably fine
