Coke nutrition facts are straightforward but easy to underestimate. A standard 12 oz can of Coke is about 140 calories with 39 g carbs, nearly all from sugar, and a modest amount of caffeine. Because it has no protein or fiber to add fullness, Coke is one of the easiest drinks to log too loosely unless the exact serving size is counted.

Part 3. Is Coke Different from Other Sodas
Compared with caffeine-free lemon-lime sodas, Coke includes caffeine as well as sugar, but the overall calorie pattern is still driven by the sweetened serving size. From a calorie-logging perspective, the biggest difference is how large the drink is and whether there were refills.
