That said, I can't say carbs are your friend. Carbs come in 2 categories: complex and simple. Simple carbs = sugar. It's like eating a table spoon of the stuff. Unfortunately, fruit and many other things (like candy) fall under this category. Use sparingly. Complex carbs are basically plants that your body takes long periods of time to digest, like vegetables, beans or pasta (note: whole wheat kinda stuff). I personally limit my carb intake to mostly vegetables and the occasional bread for sandwiches (I just couldn't give up sandwiches). Get some frozen veggies from your local super market, as they're only 1-2 dollars per bag and last a long time. Each bag will give you 2 or even 3 servings. Just steam it in the microwave really quickly.
Fats: Fat isn't necessarily bad for you, despite what many will tell you. Your body can get its fuel from 3 places (and in this order): carbs >> fats >> protein. If you don't have a lot of carbs in your diet, your body will have to get its energy from your stored fat. This is a good thing. Not only does your body have to work harder for that energy (yay burning calories), but fatty things taste so good. I'm not saying it's ok to live off of southern comfort food -- it's not. I'm saying things like oils you use to cook in your food or omega-6 found in corn/grains or omega-3 found in some fish and nuts and such. They're all good for you. Your body actually needs and is composed of a lot of fat, even within cell membranes. You shouldn't avoid it. You can go cheap this way by snacking on things like almonds or cooking your meats (next part) in various oils.
Proteins: Ah yes. Meat. The primary staple (assuming you don't have dietary restrictions) of your meals. If you can get a Costco/Sams Club kind of deal (go in on it with your friends -- that's what I did in college), you can get a several pound bag of chicken breasts for like... 5 dollars (has over a dozen in the bag). It's fantastic. Protein is awesome because it keeps you going. Not like sugar keeps you awake, but it helps repair your body after it breaks down; which is exactly what exercise (yes, even walking) will do. You can also get protein in the form of beans.
Exercise: A very large portion of weight loss will come from diet. Remember that. Exercise will help, as well, but it won't play as big of a role. Walking is a good start if you're over weight. Body weight exercises (like pushups/crunches/pullups/wall squats/etc) are also very cheap ($0) and can be a fantastic workout.
There are plenty of places online to find information about both nutrition and exercise. Just make sure to be careful to judge credentials for both places and make a proper, informed decision that can keep you safe, as well as help keep your expenses down.
