Weight gain is a slow an steady process.
Healthy muscle gain is what is more important
A balanced diet will promote muscle and over all development. In case of non-vegetarians, there are lots of option to select from. For pure vegetarians there are many combinations of foods that promote muscle growth. I do not favour protein supplements unless you are a sports person.
Pulses, Soya, cruciferous vegetables, dairy products and whole cereals promote muscle gain. Along side proper exercise and a healthy lifestyle aids in overall developmemt.
