Coca-Cola Zero or Coke Zero is a product of the Coca-Cola Company. It is a low-calorie variation of Coca-Cola. In the United States, where the drink was first introduced, Coke Zero is marketed as having zero calories[1] (hence the Zero in the product's name), but in other countries it is marketed as having zero sugar[2]. Coca-Cola Zero does in fact contain a trace amount of calories. Depending on the country in which it is made, it has about 0.2 to 0.5 calories per 100 mL (3.4 US fl. oz.)[3].
