Demystifying the calorie count of a cucumber
The number of calories in a single cucumber depends on its size. A large cucumber, weighing about 300 grams (11 ounces), contains roughly 45 calories. A medium cucumber, typically around 200 grams, has closer to 30 calories, while a half-cup serving of sliced cucumber (about 52 grams) has only 8 calories. Its exceptionally high water content is the main reason for this low energy density, making it a filling and guilt-free snack.
