Coffee is a favorite pick-me-up for many people. However, if you are diabetic or watching your weight, it's important to know just how much caffeine and calories you're getting in that 12-ounce coffee with sugar and cream.
According to the USDA National Nutrient Database, a 12-ounce cup of brewed coffee has 4 calories. A report from the University of Utah reports that an 8-ounce cup of generic brewed coffee has 80 to 135 milligrams of caffeine.
If you choose to add real granulated sugar to your coffee, the USDA reports that one teaspoon of sugar has 16 calories. If you prefer to add a sugar substitute such as Splenda, MedlinePlus.com confirms that this adds no calories to your coffee.
When you add half-and-half to your coffee as cream, you add 20 calories for every tablespoon. If you choose light cream instead, you add 29 calories per tablespoon. Choosing flavored creamers will also add additional fat and sugar calories.
