Not Keto
Cola (Regular)
38.30g net carbs per 12 oz
Sweet and fizzy, one 12 oz can carries 38.3 g net carbs, all of it sugar, which blows past a full day's keto carb budget in a single drink. Skip it and reach for sparkling water or a diet soda sweetened with stevia or erythritol instead.

Good to Know
A standard can of Coca-Cola or Pepsi gets that whole carb load from high-fructose corn syrup or cane sugar, with zero fiber to soften the hit. Watch the fountain and 20 oz bottle sizes, since they scale the sugar up well past these numbers. If you want the cola taste without the carbs, the zero-sugar versions (Coke Zero, Pepsi Zero Sugar, Diet Coke) use aspartame or sucralose and land at roughly 0 g net carbs instead.
Is Cola (Regular) Keto? The Full Answer
Cola contains 38.30g net carbs per 12 oz (38.30g total carbs minus 0.00g fiber). Sweet and fizzy, one 12 oz can carries 38.3 g net carbs, all of it sugar, which blows past a full day's keto carb budget in a single drink. Skip it and reach for sparkling water or a diet soda sweetened with stevia or erythritol instead.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 191% of a 20g daily carb limit. If you are following a strict ketogenic protocol, reach for a lower-carb option instead.
Better Keto Swaps
One can of regular cola packs 38.3 g of net carbs, which is enough to blow past a typical day's keto budget in a single drink. Swap it for something that scratches the same fizzy itch without the sugar. Diet Coke or Coke Zero Sugar gives you that same cola taste with about 0 g net carbs per 12 oz, so you can drink it freely. Want a more natural option? Zevia's cola is sweetened with stevia and clocks in at 0 g net carbs per can. Plain sparkling water (think LaCroix or Topo Chico) is another easy pick at 0 g net carbs, and a squeeze of lime or a splash of sugar-free flavor syrup makes it feel like a treat.
