weight problem

[ICB]

A good way is look at your Father, that gives you clues althougth not always right.

my father is about 185cm and weighs over 90 kg, my goal is to weigh as much as him when I grow up, but if I weigh only this little now is it possible for me to weigh as much as him when I become an adult?

Of course it is i have always been naturally slim, when i was 16 i was a rake. But i put on 20+ pounds by increasing the calories and lifting heavyweights. Im 6'1 165 pounds now and im 19 now by the way. But i wouldn't be worrying too much about your weight at your age. You still got alot of growing to do.
