It honestly depends on how much sugar, fat, excersise,ect the person gets daily. On average a boy should be around 100-140 pounds.
Hope this helps.
a 6 foot 15 year old boy should be weighing around the 135-155 pound mark.but don't worry if you are slightly over because you could have more muscles than fat.
An eleven year old boy should have 2,300 mg a day
There really is no specific limit to how much a fourteen year old boy should weigh. It depends on how tall you are, because if you were 5' 9", you should weigh more than a fourteen year old boy who is 5' 2".
