For food products to be labeled “light,” the U.S. Food and Drug Administration requires that the altered product must contain either at least one-third fewer calories than the regular product or at least one-half less fat than the regular product. If a serving of Miracle Whip® Light contains 20 calories and 1.5 grams of fat, then what must be true about either the number of calories or the grams of fat in a serving of regular Miracle Whip®?
