Is It Really Zero Calories?
Diet soda is advertised as a zero-calorie beverage, but the reality is a bit more complex. Most diet sodas contain fewer than 5 calories per serving, which allows them to be labeled as zero-calorie according to FDA regulations. However, those small amounts can accumulate if you consume multiple cans per day.
Calories and Metabolic Effects
While the caloric content is negligible, diet soda may still have an effect on your body’s metabolism, particularly due to the use of artificial sweeteners.
Conclusion
Though diet soda is nearly zero-calorie, it’s not completely free of calories. Be mindful of how much you consume, especially if you drink it frequently.
