What you choose to eat is important but just as important is knowing how much you eat. You regular readers know I am always saying to read the nutrition labels of everything you eat and serving size is one of the reasons why. It doesn't matter how many calories, fat, etc it says per serving if you don't look to see how many servings are in the bag, can, package, bottle, etc. If you pick up a bag of candy, for example, and you read the nutrition facts thinking, "Oh that's not too bad", you could be wrong. That information is listed per serving so if that bag contains 2 or 3 servings and you eat the whole bag, well you just ate 2 to 3 times what you think you did in calories, etc. With nuts, chips, etc, the serving size is often counted per nut, chip, etc. Pay attention to your serving sizes and eat accordingly.
