You didn't mention ur height
its not good to gain weight just like that.
it should be co-related to ur height
check your Body Mass Index
if ur BMI is less than required, try these eating strategies to gain weight.
don't try any kind of protein capsules/drinks that may contain steroids
, which is too harmful for your health. Gain weight only through natural ways, that is by eating highly protein contained vegetables.
all the best
