There are 140 calories in a can of Coke as well as 39 grams of carbs, according to Coca-Cola. There are 187 calories in a 16-ounce Coke, as well as 52 grams of carbs — that’s almost 10 percent of the total calorie intake for someone who eats 2,000 calories per day. The calories in Coke come from sugar, so you’re not gaining nutritional value from the drink.
