                                According to the USDA, a standard 8-ounce cup of brewed black coffee contains just 2 to 5 calories, making it a virtually calorie-free beverage. This surprising fact reveals that the calories in your daily coffee almost exclusively come from the additions you pour into your cup, not the coffee itself.
