Brief Answer:
Protein XXXXXXX foods along with exercise will help.

Detailed Answer:
Hi,
Thanks for writing your query.

After reading your post, I would like to advise that you should eat protein XXXXXXX foods like cheese, soyabean, milk products, etc.
If you eat egg(some vegetarians eat egg), it is also beneficial.

You should also consult a gym trainer as isometric exercises will help in building muscle mass and thereby help in increasing body weight.

Donot go for protein supplements available in the market. They can cause harm if consumed in wrong method.

You should eat healthy and fresh fruits and vegetables as they will help in keeping the body healthy and disease free.

Also drink at least 8-10 glasses of water daily.

I hope this is helpful to you.
If you have any further query, I will be happy to help.
Thanks.
