How to gain 5 kilograms in one month?
2 bottles of pure milk every day, breakfast once in the morning and once in the evening. You should watch TV at noon and at night. Watching TV and eating will make you fat, but don't overdo it. Be sure to eat enough for dinner, because you won't exercise after eating at night. You can't do a lot of exercise after dinner, and you will get fat when you sleep, but I don't recommend you to do this for a long time.
