Start smoking, you'll lose some weight.

Ugh you all fail response, only one that makes sense is exploits.

Some food suggestions to getting more weight would be
Potatoes:
French Fries
Baked Potatoes
Chilie Fries
Potato Salad

those are just some ways to enjoy eating potatoes

Try working out, you are going to want keep working out until you feel a little bit tired, then take a 1 minute break and go back to it.

Lifting weights should help increase muscle mass which is healthier than gaining just fat. But you still need to eat alot so you gain fat so you can have something to burn off. Otherwise you will be burning off muscle instead, and we don't want that. That burn you may feel is called latic acid build up. Latic acid is a good thing in most cases, it help you digest food, burn off fat, but it also can make your throat hurt. There has been numerous times when someone has a "acid reflex". They will start to cough and breathe more heavily. What you want to do is por yourself a tall glass of milk. I personally don't know any ways to avoid it, I never bothered to learn the whole thing.

So this might help you in weight gain, I already gained 10 pounds in 1 month by doing those steps.
If you want, you could also purchase vitamins or protein whey. They are full of nutrients and can help you gain weight/muscle mass.
