FAQs

What is DIET PEPSI®?

DIET PEPSI® is a zero-calorie, sugar-free soft drink that delivers the bold and refreshing cola flavor of classic Pepsi®, without the added sugars or calories. It’s sweetened with a blend of artificial sweeteners—aspartame and acesulfame potassium—to mimic the taste of regular cola while remaining completely calorie-free. The result is a crisp, fizzy drink that has become a go-to choice for people managing their weight, watching their sugar intake, or simply looking for a lighter beverage. Offered widely at Pizza Hut, DIET PEPSI® is an ideal refreshment to accompany pizza, wings, pasta, and more.

How many calories are in DIET PEPSI®?

DIET PEPSI® contains absolutely zero calories in a standard 20 oz serving. Unlike traditional colas that may contain more than 250 calories per bottle, DIET PEPSI® uses artificial sweeteners to provide sweetness without any caloric content. This makes it a great beverage option for those on calorie-controlled diets, low-carb meal plans, or for anyone who just wants to enjoy soda without worrying about added sugar or energy intake.

Does DIET PEPSI® contain caffeine?

Yes, DIET PEPSI® does contain caffeine, with approximately 34 milligrams per 20 oz serving. This level of caffeine is considered moderate and provides a subtle pick-me-up, making it a suitable choice for lunch, dinner, or even late-night meals. It’s not as highly caffeinated as energy drinks or strong coffee, but enough to help refresh and reinvigorate without overstimulation. For people who are sensitive to caffeine, it’s best consumed in moderation.

Is DIET PEPSI® available at every Pizza Hut?

Most Pizza Hut restaurants in the U.S. do offer DIET PEPSI® as part of their standard beverage menu. However, availability can vary depending on the franchise location, local supplier contracts, or regional preferences. While it’s commonly found alongside other PepsiCo beverages like Mountain Dew® and regular Pepsi®, it’s always wise to check your specific store’s online menu or call ahead if you’re set on having DIET PEPSI® with your meal. If it’s not available, similar diet soft drinks may be offered instead.

Can I get DIET PEPSI® with delivery orders?

Absolutely. DIET PEPSI® is available for delivery, carryout, and dine-in at most Pizza Hut locations. When placing an order via Pizza Hut’s official website, mobile app, or even third-party platforms like DoorDash, Uber Eats, or Grubhub, you can easily select DIET PEPSI® as your preferred beverage during checkout. It usually comes in a sealed 20 oz bottle or a fountain drink cup, ensuring freshness and convenience, no matter how you dine.

Is DIET PEPSI® sweetened?

Yes, DIET PEPSI® is sweetened using two widely-used, zero-calorie artificial sweeteners: aspartame and acesulfame potassium. These ingredients are approved by the U.S. Food and Drug Administration (FDA) and are commonly used in diet sodas to provide a sugar-free alternative that still satisfies the craving for sweetness. Together, they help replicate the taste of classic Pepsi® without the sugar and without spiking blood sugar levels, making DIET PEPSI® suitable for a wide range of dietary preferences and health goals.

Is DIET PEPSI® gluten-free?

Yes, DIET PEPSI® is entirely gluten-free. It contains no ingredients derived from wheat, barley, rye, or any gluten-containing grain, and is generally considered safe for people with gluten intolerance or celiac disease. Since it’s produced in controlled environments and packaged in sealed bottles or handled by dedicated dispensers, there’s minimal risk of cross-contamination. Still, if you have severe gluten sensitivity, you may wish to confirm procedures with staff at your Pizza Hut location just to be safe.

Is DIET PEPSI® vegan-friendly?

Yes, DIET PEPSI® is generally accepted as vegan-friendly, as it contains no animal-derived ingredients. The ingredients list includes water, caramel color, caffeine, sweeteners, and preservatives—none of which are sourced from animals. Some strict vegans do raise concerns about caramel color, which may be processed using bone char in some instances. However, PepsiCo has publicly stated that the caramel coloring used in DIET PEPSI® is not derived from animal sources, making it a safe option for the majority of plant-based consumers.

Is DIET PEPSI® a good option for people with diabetes?

Yes, DIET PEPSI® is considered safe for most people with diabetes, as it contains no sugar and no carbohydrates. Since it doesn’t affect blood glucose levels, it can be enjoyed as a sweet beverage alternative without interfering with blood sugar control. However, because it’s sweetened with aspartame and acesulfame potassium, people with sensitivities to artificial sweeteners or specific medical conditions like phenylketonuria (PKU) should consult with a healthcare professional before consumption.

What foods go well with DIET PEPSI®?

DIET PEPSI® is a versatile drink that complements a wide variety of Pizza Hut menu items. Its crisp, refreshing cola flavor cuts through the richness of cheesy pizzas, spicy buffalo wings, creamy pasta dishes, and buttery garlic breadsticks. It’s also an excellent contrast to sweet items like Cinnabon® Mini Rolls or Chocolate Chip Cookies, offering a refreshing balance without adding more sugar to your meal. The carbonation and tangy flavor help cleanse your palate, making each bite taste just as good as the first.
