Is Coke Zero Keto?

Yes — fits your limit

0g net carbs per 1 can (12 fl oz)

One serving is 0% of a 20 g day.

Recalculates as you change it.

0 g total carbohydrate − 0 g fibre = 0 g net carbs, against a 20 g daily limit — 0% of the day. We call it a fit at 25% of your limit or less, a maybe up to 50%, and a no above that.

Why

Aspartame and acesulfame potassium do the sweetening. Neither contributes carbohydrate, so the panel reads zero across the board.

Coke Zero and Diet Coke are the same answer to this question and different drinks. Zero Sugar is formulated to taste like classic Coca-Cola; Diet Coke was never trying to. Neither spends any of your carb budget.

Common questions

Is Coke Zero the same as Diet Coke on keto?
For carbohydrate, yes — both are zero. They differ in flavour formulation and sweetener blend.
Will Coke Zero stop weight loss?
Not through carbohydrate. If it changes how much you eat, that is the mechanism worth paying attention to, and it is personal.
Is there caffeine in it?
Yes, and there is a caffeine-free version of the same formula.
