Diet Pepsi is a sugar-free soft drink produced by PepsiCo. It is a low-calorie alternative to regular Pepsi, sweetened with artificial sweeteners like aspartame and/or acesulfame potassium. This makes it popular among those looking to reduce their sugar intake or manage their weight. First introduced in 1964, Diet Pepsi has undergone various reformulations and branding changes over the years. It is available in several flavors, including Diet Pepsi Wild Cherry and Diet Pepsi Lime, catering to diverse consumer preferences while maintaining its core identity as a refreshing, calorie-conscious beverage.
