there are no super-solutions my friend. your height and weight is more likely to be genetically determined (blame it on your parents) so it not likely you will ever get taller than you are now. by age 18 the growth plates have closed. gaining weight is another issue and even this may be difficult for you to circumvent nature. eating a well-balanced diet with sufficient calories is really the best you can do. the rest is up to your metabolism. when you are 50 or 60 you may laugh about the time you wanted to gain more.
