By Shumaila Saeed || Updated on December 25, 2023

Diet Pepsi vs. Pepsi Zero Sugar

Key Differences

Diet Pepsi is marketed towards those looking to reduce their calorie intake without giving up soft drinks. It's sweetened with aspartame, giving it a distinct taste separate from Pepsi's regular variety. Pepsi Zero Sugar, meanwhile, is intended to mimic the taste of original Pepsi more closely while still offering a no-calorie, sugar-free option. It uses a blend of artificial sweeteners including aspartame and Ace-K (acesulfame potassium).

While both Diet Pepsi and Pepsi Zero Sugar offer sugar-free alternatives to regular Pepsi, they cater to different consumer tastes and preferences. Diet Pepsi has been around since the 1960s and has a dedicated consumer base that prefers its specific flavor profile. Pepsi Zero Sugar was introduced much later, initially as Pepsi Max in some markets, and is targeted at consumers who desire a taste closer to that of full-sugar Pepsi.
