Swapping high-calorie foods for lower calorie choices

Simple swaps can make a big difference when it comes to cutting calories. For example, you can save 60 calories a glass by drinking fat-free milk instead of whole milk. Instead of having a second slice of pizza, reach for some fresh fruit. Or snack on air-popped popcorn instead of chips. Eat more fruits and vegetables, which have many nutrients and are high in fiber. And they'll fill you up more than high-fat choices.
