Body weight of a person depend upon many things like genetics, diet, lifestyle etc. We can't change any genetic factor but we can change our life style to build muscles and increase weight. To gain weight naturally, a good balanced diet is required. Fruits, vegetables, proteins (cereals, grains, nonveg and egg are rich in protein), milk and yoghurt etc is required to be taken daily. Proteins will help in building muscle mass. The other thing you should do is exercise regularly like swimming, cycling or jogging. You can also join a gym as appetite increases after exercising. Exercise is of paramount importance because it releases endorphins from the body. This will increase your stamina also. Also sound sleep is required without any disturbance for 7-8 hours a day, as this increases the release of growth hormone and other enzymes to build your tissue. At your age the growth hormone mainly act in buliding mass so if you follow the above instruction your weight will increase at faster rate. I hope this information helps you. Feel free to ask if any further query and I will be glad to answer them. Wish you good health. Enjoy your life. Ebola symptoms.
