Fruit

Grab an apple, banana, pear, grapes, or other portable fruit as you dash out the door every morning. If you grab a different fruit every day (and change with the seasons), you'll obtain a good variety of nutrients plus fiber, and won't get bored with the same old snack. The average serving of fruit is around 70 calories so pair with a cup of fat-free milk (about 90 calories) for a protein boost as well as extra calcium and vitamin D. This protein and fiber combination will keep you feeling full and prevent mindless eating.
