Help...

Hey, I'm 5'5, 13 years old and I weigh around 90 pounds. Am I under weight?? If I am then how can I gain more weight??

I eat fast food once a week and I always eat chocolate, but I don't know why I don't gain more weight. I thought fast food is supposed to make you fat.😕

heyy sania!
to see if ur under or over wieght or the right weight... bmi is a gd way! this is all it is...

weight in kg divided by height in metres squared (btw.. only height is squared.. then u divide the weight by it)

if u get a number between 20 and 25 u are the right weight for ur height... if ur above 25, ur overweight and if ur under 20.. ur underweight!

hope it helps! x
