10 Foods that Fill You Up While You Trim Down

Zero-calorie foods are too good to be true, but veggies like cucumbers, carrots, zucchini, celery, broccoli, and cabbage come pretty close. Since they're made up of mostly water and fiber, they’re naturally very low in calories. “Fiber also adds bulk to foods, which gives you the satisfaction of chewing, plus the feeling of a full stomach,” notes Zuckerbrot. If you’re not a raw veggies type of guy, use produce to bulk up sandwiches, soups, and omelets.
