Keto and the Fizz: Can You Drink Flavored Sparkling Water?
For people on a keto diet, the refreshing taste of sparkling water is a good alternative to plain water. When the water is flavored, it is even more appealing. However, not all flavored sparkling waters are the same. Their compatibility with keto depends on the ingredients. By understanding the labels, you can enjoy these drinks without affecting ketosis.
Read the Label: Your First Step
Always check the nutrition facts and ingredient list when considering flavored sparkling water. Keto-friendly sparkling waters have zero calories, zero sugar, and zero net carbs. The label will help avoid products with misleading information.
Key ingredients to look for include:
- Carbonated Water
- Natural Flavors
Avoid these ingredients:
- Sugar or cane sugar
- Fruit juice concentrate
- Aspartame, Sucralose
- High-fructose corn syrup
Natural vs. Artificial Sweeteners
Some flavored sparkling waters use artificial sweeteners like aspartame or sucralose. Others use natural, zero-calorie sweeteners like stevia or monk fruit extract.
Artificial sweeteners do not contain carbs and usually do not break ketosis. However, some people prefer to avoid them due to possible side effects. Some studies suggest artificial sweeteners can increase sugar cravings or impact gut bacteria. However, the response varies, and some find them helpful for staying on track.
Naturally sweetened options are often preferred by keto dieters. Stevia, monk fruit, and erythritol are considered the most keto-friendly.
The Problem with Fruit Juice Concentrate
Some brands use a small amount of fruit juice for flavor. This adds carbs and calories. A can of Spindrift may have 1-3 grams of net carbs. These must be accounted for in your daily macros to avoid exceeding your limit and disrupting ketosis.

FAQs
