Hello there...I can understand your concern. It is important that you gain muscle mass and not fat. Ideal weight for your height is about 67kgs. As you know few people have very high basic metabolism rate. It will be difficult for them to gain weight. Also one should remember gaining weight and losing weight is a very gradual process. It will a lot of time, patience and determination. You must follow a healthy diet and exercise schedule. Start having food rich in proteins like pulses, soyabeans, vegetables, fruits, egg whiteboiled , boiled chicken. Regarding exercises, start cycling or swimming or gyming, whatever you are comfortable with and enjoy most. You can also visit a dietician and endocrinologist for further queries.
