According to a 2025 study from UNC Health Appalachian, zero-sugar sodas are not a long-term solution for weight loss or better health, despite their reduced sugar content. Both zero sugar and diet sodas aim to be calorie-free alternatives to traditional sugar-sweetened beverages, but their minor differences in ingredients and marketing have led many to question: is zero sugar or diet soda healthier?

While both contain zero calories and no sugar, diet ginger ale is not exactly the same as zero sugar ginger ale. The primary difference lies in the specific blend of artificial sweeteners used to achieve their distinct flavor profiles and marketing appeal. This nuance explains why some drinkers prefer one over the other.

According to the Center for Science in the Public Interest, Diet Coke contains significantly more caffeine than Coke Zero, with 46 mg per 12-ounce can compared to 34 mg in the same serving size. This disparity in caffeine content, along with differences in their artificial sweeteners, creates a distinct flavor profile for each diet soda.
