How do i get fatter? i want to gain like 5 kg....

I suggest that you take a long term diet, lets say 5 months or so - 1 kg for each month. A faster diet could be less healthy for your body. 

You will have to add 300-400 calories each day, so try to write some kind of log book.Don't be temptated to eat choclate or eggs to make your weight gaining any faster.  

Do you really want to gain fat or lean muscle mass?  There is a difference.  If its fat you want go for the high calorie foods.  But if its lean muscle mass which will make your body sexy, tone and attractive no matter who you are!  Then you need a personalized nutrition plan with a great workout plan designed just for you and your goals, contact me at http://www.betterbodiesbycarmel.com/ Carmel-ISSA Certified Personal Trainer
