About the Fanta Zero
Fanta Zero at Burger King costs £2.69 and carries 87 kcal, which is the highest count among the sugar free soft drinks here and the detail most people miss. The zero on the label refers to sugar rather than to calories, and orange carries more than the colas do.
It is still far below the full sugar options, so the swap is worth making. The point is only that this is not the same as choosing Sprite Zero or Diet Coca-Cola, which sit in single figures. If the count is what you are managing, those two are the cleaner picks.
Where it wins is flavour with a meal. Orange holds its own against a heavily sauced burger better than lemon and lime, and it is the option children will pick without being asked twice.
Size makes a difference here that it does not make with the colas. The large carries 119 kcal against 87 in the regular, so stepping up adds 32 kcal rather than the one or two a Diet Coke would. It is priced level with Coca-Cola Zero, Diet Coca-Cola and Sprite Zero, all four sharing the same figure, so the whole sugar free row costs the same and only the calorie counts separate them.
