Answer: Coke Zero is a keto-friendly diet soda.
Coke Zero contains no carbohydrates, so it won't count against your carb limits for the day.
It's worth noting that its sweeteners are aspartame and acesulfame potassium, which are unpopular ingredients in the keto community, though there hasn't been conclusive research linking them to negative health effects.
For a soda with more natural ingredients, consider Zevia. It's sweetened with stevia, a natrual, keto-friendly sweetener that does not increase blood sugar. Or carbonate your own tap water using a home carbonation product such as Sodastream or the Hamilton Beach Fizzini.
