Size tip: A Large Diet Lemonade contains only 80 calories, compared with 380 calories in a Large regular Lemonade—a difference of 300 calories.

Chick-fil-A Diet Lemonade contains three main components:

  • Real lemon juice: Not from concentrate, providing a naturally tart citrus flavor.
  • Water: Creates the refreshing lemonade base.
  • Splenda sweetener: A blend containing dextrose, maltodextrin, and sucralose.

Ingredient highlight: Diet Lemonade contains no added cane sugar in its standard recipe. However, it isn’t calorie-free because lemon juice and sweetener ingredients contribute carbohydrates.
