I weight more than 75kg and just 5 ft. what should i do to lose some of those kilos and to grow taller for 2 months if i'm not allowed heavy exercise?

Grow taller for 2mo?: Time to go see your family doctor. Too many missing details. Why aren't you allowed "heavy exercise"? Why do you want "to grow taller for 2 months"? Not much you can do to affect your height besides eat right & choose your parents carefully. Your height is typically based to a great deal upon your parents. Your weight, however, is under your control. 3, 500 kcal = 1 pound. Eat less & exercise more.
