That's the beauty of just flat-out counting calories. You don't have to avoid carbs or avoid fats, etc. Just eat obviously healthy foods as much as possible. You can find the calories for pretty much any food online until you get the basic idea.

Eat whole grains instead of other grains if possible (oatmeal instead of cereal, whole wheat instead of white)
Don't eat hydrogenated oil
Don't eat artificial ingredients
Eat plants like the other guy said
And if you're going to exercise, don't do atkins. Your body needs some carbs (,not as many as most people eat, though,) for fuel and completely eliminating them is not only bad for you, but you would probably not have the best disposition because carbs affect your mood. But I'm talking fruits, veggies, and whole grains.
