Hi Doctors, I am 28 years old, weigh around 55 kgs, unmarried, working in Delhi for over 5 years. My lifestyle is not that good as I could not have balanced diet and proper sleep sometimes because of office works. Can I have protinex or similar kind of protein supplement to gain weight which should be permanently and for the period I am taking supplement. Kindly advise a 100% safe health supplement / protein to gain weight which I can have without going to Gym. Thanks a lot. Regards.
