Well, since the prevailing wisdom that carbs are responsible for weight gain, I'd say start eating more healthy carbs in whatever form you body can tolerate. That's assuming you don't have blood sugar issues of course.

For example, eat a lot of beans, fruit, dairy, and whole grains. Bananas esp. are loaded with carbs. Likewise, sweet potatoes are loaded and are really good for you. Popcorn is a good carb-laden snack with fiber, and put butter on it! Nuts are loaded with calories, healthy fat, and some carbs. Cashews are one of the higher carb nuts.

Here's a good article from the New York Times that summarizes the results of an NIH-sponsored research study on low carb vs. low fat diets for weight loss and heart health. If you believe what the results of the study say, then to gain weight, you want to up your carbs. Of course you would want to try to do healthy carbs instead of junk and sugar-laden foods. Although personally, I would allow for nice high fat ice cream.
