Yay! I'm not the only one here trying to get UP to a healthy weight!
Pasta seems to be the only thing I can eat that won't just burn up right away. Try that. Also, if you drink milk, make sure you're drinking whole milk, and consider adding creme. It'll taste better, and you'll be adding UNSATURATED fats to your diet that your body will make better us of than saturated fats. Avoid sugars and saturated fats, in favor of fiber, protein, and unsaturated fat. If you're not vegetarian like I am, make sure meats that you eat are lean, and high in iron, unsaturated fat, and protein. Avoid salted meats when possible.
A few other things you might want to add more of to your diet are:
Rice
Lentils
Avacados
Black Beans
Cheeses
Good luck! ;]
