Is Coke Zero Keto Friendly?

Coca-Cola Zero Sugar, more commonly known as Coke Zero, is a popular soda from the Coca-Cola Company. Many people love its taste, which is similar to the original Coca-Cola Classic. The significant difference is that Coke Zero contains zero sugars and hence, zero calories.

It’s important to note that while it doesn’t have any sugar, it does contain artificial sweeteners like aspartame and acesulfame potassium. These sweeteners give Coke Zero its sweet taste without the added calories or carbs.

The big question is whether this food product fits into a ketogenic diet. The answer is yes! A low-carb diet like the keto diet focuses on keeping your daily net carbs under 20 grams to maintain ketosis. Coke Zero has zero net carbs, so it can be classified as keto-approved on our scale.

However, suppose you’re worried about the effects of these artificial sweeteners on your insulin response and blood sugar levels. In that case, you might want to consider other options like Zevia, which uses Stevia instead. Despite this concern, many keto dieters still enjoy Coke Zero without affecting their state of ketosis.

So there you go! Whether you’re craving something fizzy during your low-carb diet or looking for an alternative to Diet Coke with no effect on your glycemic index, Coca-Cola Zero Sugar could be your go-to soda!
