Along with your vegetables, add in fruits, lean protein, whole grains and lots of water. Essentially, "make the healthy choice the easy choice," says Jim Kauffman, national director for health and well-being for YMCA of the USA in Chicago. For example, "fill a water bottle at the beginning of the day, and put it right in front of you," he says. Also, "don't eat out of a package. If you do, only get the correct portion size."
