Diet Sport was a variation of Sport that used almost the exact formula but had no calories, 0 grams of carbohydrates and sugars.


Following the release of Sport in 1989, a 2-calorie version and a Diet version were also released. All three lasted until 1991 when they were later discontinued.


Mountain Dew Sport and Diet Sport both retained the original citrus flavor of Mountain Dew, as well as the yellow-green color.
