How Many Calories Are in a Cup of Green Tea?

Green tea, derived from the unfermented leaves of the Camellia sinensis plant, is a popular beverage worldwide. For anyone monitoring their food intake, understanding the caloric content of beverages is important. While many drinks contribute significantly to daily calorie counts, green tea is distinct. The calorie question is not a simple yes or no answer, as the final drink often includes more than just steeped tea leaves and water.

The Calorie Content of Plain Green Tea

A standard 8-ounce cup of plain green tea, brewed using only dried leaves and hot water, contains a negligible number of calories. The count is typically zero to two calories per cup, making it essentially calorie-free. This near-zero count is because the infusion process extracts only trace amounts of macronutrients from the tea leaves.

The small number of calories present comes from minute quantities of carbohydrates and amino acids that dissolve into the water during steeping. Since these components are so diluted, the green tea beverage is almost entirely water. This minimal caloric contribution is consistent across different types of pure tea, including black, white, and oolong varieties.

Hidden Calories from Common Additions

The caloric impact of green tea shifts drastically once additions are introduced, as the tea itself is no longer the main source of energy. A single teaspoon of granulated white sugar adds approximately 16 calories to the drink. Many commercial preparations or home recipes use more than one teaspoon, quickly multiplying this effect.

Honey, often viewed as a healthier alternative, is slightly more calorically dense than table sugar by volume. One teaspoon of honey contains about 21 calories. Because it is a liquid, people often pour larger, unmeasured amounts of honey or agave syrup into their tea, leading to a significant calorie increase.

Adding milk or cream also substantially elevates the calorie count. For instance, incorporating four ounces of whole milk to make a milk tea adds about 75 calories. Commercial green tea lattes or bottled, sweetened teas often include multiple tablespoons of sugar and high-fat milk or powdered creamers. These drinks can easily contain 50 to over 200 calories per serving. Syrups used to add flavors like vanilla or caramel are concentrated sugar solutions and are a major source of hidden calories in specialty tea drinks.

Green Tea’s Role in Calorie-Controlled Diets

The virtually calorie-free nature of plain green tea makes it an excellent choice for individuals managing their calorie intake. Replacing high-calorie drinks like soda, sweetened juices, or elaborate coffee beverages with plain green tea can significantly reduce daily energy consumption. This simple substitution is a straightforward strategy for creating a calorie deficit over time.

Beyond its low calorie count, green tea contains compounds that may support weight management efforts. It naturally contains caffeine and antioxidants called catechins, particularly epigallocatechin gallate (EGCG). These compounds are believed to promote a minor increase in the body’s energy expenditure and fat oxidation. While the effects from the brewed tea are modest, it contributes to overall hydration and offers a non-caloric boost that can complement a balanced diet and regular physical activity.
