I don't know why you would want to gain weight... but my friend has a low white blood cell count and he always has to try to put on weight cause he is not healthy so he puts lard in his food. you can gain like 10 pounds in a week but I would not suggest it

you should eat lots of penuts eat late

Eat a lot of Mayonnaise and peanut butter sandwiches and drink a lot of Mountain Dew and take a weight gain supplement which can be purchased at any G.N.C supplement store. and start lifting weights. Happy weight gain.
