Fact checkWhy other sites disagree about this item
Most listings show Diet Pepsi and stop, missing that KFC fountains carry Pepsi Zero Sugar as a separate tap; a few print regular Pepsi's 210 calories against it. It is a zero-calorie cola in every size; the figures here are the medium serving.

Where the sodium lands
About 40 mg for a medium, 2% of the daily value. It contributes nothing meaningful to a combo's sodium, which is why this site's drink swaps only ever change the calorie line.

What is Pepsi Zero Sugar at KFC?
PepsiCo’s zero-calorie cola, sweetened with aspartame and acesulfame potassium, on the fountain at every KFC alongside regular Pepsi and Diet Pepsi. It tastes closer to regular Pepsi than Diet does, which is the whole reason it exists, and it carries slightly more caffeine than either. Every combo, box and Fill Up takes it as the drink at no upcharge.
How it is served
Fountain, over ice, in small, medium and large, with free refills at most dine-in locations. Zero calories in every size, which is the one line on this site where the cup size does not matter. The app does not default to it; you have to pick it.
Who it suits, and who should skip it
Anyone counting: every combo on this site quotes a range whose bottom number assumes this drink. Cola drinkers who found Diet Pepsi thin; people who want the caffeine without the 58 g of sugar. Skip it if you avoid artificial sweeteners, in which case unsweet tea or water are the only zero-calorie taps, and skip the large: it is the same nothing in a bigger cup.
Is it worth the price?
Same price as regular, and it takes 210 calories off any combo. The best free upgrade on the menu.
At $2.99 for a medium it costs exactly what regular Pepsi costs, so the choice is nutrition rather than money: 210 calories and 58 g of sugar versus none. On a Famous Bowl Combo that is the difference between 800 and 590; on the $11 Box Feast between 1,610 and 1,400. Like every drink here it carries no value grade; its value is what it subtracts.
Order hacks
- Pick it by default in combos and every calorie figure on this site’s pages drops to the lower number.
- Order the small: zero calories in every size, and dine-in refills are free at most stores.
- It carries slightly more caffeine than regular Pepsi; unsweet tea or water are the caffeine-free zero options.
- Prefer it to Diet Pepsi if you want the regular-Pepsi taste; Diet is the lighter, sharper cola.
- On delivery apps it is often listed only as “Pepsi”; check the size and variant before you pay the markup.
