  2. Good evening Mr Arrya.
    Height is usually a debatable topic as it is mostly genetics, ie, if your parents are short, you may be couple of inches taller than them at most.
    You may advise your brother , not to worry, keep himself healthy and fit as nowadays trend is to be lean and muscular and fit.
    Alternatively ask him to take proteins in his diet like eggs, meat, lentils etc., play games esp basketball, cricket, etc.

    Wish him all the best in his studies from me!

    Live healthy!
  3. Please refer to my above advise.
