Burger King Diet Coca-Cola

About the Diet Coca-Cola

Diet Coca-Cola at Burger King costs £2.69 and carries 1 kcal, which is effectively nothing. That single figure is the whole argument for ordering it: swapping from full sugar Coca-Cola to this removes a couple of hundred calories from a meal without changing the food at all.

It is the single easiest change anyone can make to a Burger King order, and the one most often skipped because the drink feels like an afterthought next to the burger. The large is 2 kcal, so size makes no difference here in a way it does everywhere else on this menu.

Against Coca-Cola Zero the calories are the same and the difference is taste rather than nutrition: Diet is the lighter, sharper of the two, Zero is built to taste like the original. Both cost the same, so pick on flavour.

Put against every drink on the menu that publishes a figure, only Bottled Water and Tea come in lower, and both of those are at zero. That makes this the lowest calorie drink here with any flavour in it at all. It shares its price with the three other sugar free soft drinks, so nothing is gained or lost by ordering it over Sprite Zero or Fanta Zero except the taste and, in Fanta's case, 86 kcal.
