Hello sir\mam! I'm 23 year old bachelor. My weight is only 47 Kg. I'm having so many problems for my thin body and less weight and I don't feel energetic to do any work. I want to increase my body weight at earliest. I don't have the opportunity to eat no of times becoz of my profession. So, considering all these things, please suggest me some food or medicine (if any) so that I can build by body as early as possible. Thank you.
