A Guide to Which Teas Have No Calories for Your Diet

Did you know that two-thirds of the world's population enjoys a daily cup of tea? When brewed and served plain, most traditional and herbal infusions are virtually calorie-free, but it's important to know which teas have no calories to avoid hidden sugars and additives.

Quick Summary

Pure, brewed teas offer a naturally calorie-free beverage perfect for supporting a healthy diet and weight management goals. Learn about the various types of teas, both from the Camellia sinensis plant and herbal varieties, that can be enjoyed guilt-free without extra sweeteners or high-calorie additions.

Key Points

• Traditional Teas Are Virtually Calorie-Free: Green, black, white, and oolong teas contain negligible calories when brewed with just water.

• Herbal Infusions Are Also Low in Calories: Many herbal teas, including chamomile, peppermint, and hibiscus, contain zero or insignificant calories when steeped plain.

• Watch Out for Additives: The calories in tea come from additions like sugar, honey, milk, and syrups, not the tea leaves themselves.

• Matcha is an Exception: Unlike steeped tea, matcha powder has a small calorie count (~6 kcal per tsp), though it offers concentrated antioxidants.

• Zero-Calorie Teas Offer More Than Just Hydration: Many teas provide antioxidants and can potentially boost metabolism, supporting overall health.

• Brew at Home for Control: The best way to ensure your tea is calorie-free is to brew it yourself, allowing you to control all ingredients.

For those mindful of their caloric intake, a warm or cold cup of tea is a fantastic, flavorful option. The key to keeping your tea calorie-free lies in avoiding certain additives. Understanding the difference between plain, brewed tea and specialty shop drinks is the first step toward making a healthy choice. Plain teas, such as green, black, white, and oolong, contain only trace amounts of carbohydrates, making them virtually calorie-free. The same is true for many popular herbal teas, which are infusions of various herbs, fruits, and flowers.

Traditional Teas: Naturally Calorie-Free

All traditional teas come from the leaves of the Camellia sinensis plant. Their classification (green, black, white, oolong) is based on the level of fermentation the leaves undergo. Regardless of the type, when brewed with plain water, these teas are negligibly low in calories.

• Green Tea: Made from unfermented leaves, green tea typically contains less than 3 calories per 8-ounce cup. It is known for its high antioxidant content, particularly catechins like EGCG, which may help boost metabolism.
• Black Tea: Fully fermented black tea also contains only about 2 calories per cup when brewed plain. It is rich in antioxidants called theaflavins and thearubigins, which offer various health benefits.
• White Tea: This minimally processed tea is harvested from young tea buds and leaves. Like other Camellia sinensis teas, it is nearly calorie-free when prepared simply.
• Oolong Tea: Partially fermented, oolong tea offers a flavor profile between green and black tea. When brewed without additions, its calorie count is minimal.

Herbal Teas and Infusions

Herbal teas are not true teas because they don’t come from the Camellia sinensis plant. Instead, they are infusions made from brewing herbs, spices, dried fruit, or flowers. Most herbal varieties are naturally caffeine-free and contain insignificant calories.

• Chamomile Tea: A popular choice for relaxation, chamomile tea contains zero calories when brewed plain.
• Peppermint Tea: This refreshing herbal tea is another excellent zero-calorie option, making it a great alternative to sugary drinks.
• Hibiscus Tea: Known for its vibrant red color and tart flavor, hibiscus tea has no calories when brewed on its own.
• Rooibos Tea: This South African herb is naturally caffeine-free and has a sweet, nutty flavor without any added calories.
• Ginger Tea: Sliced fresh ginger root brewed in hot water provides a soothing, calorie-free beverage.
• Dandelion Tea: Made from the leaves or roots of the dandelion plant, this herbal tea is a natural diuretic and contains zero calories.

The Impact of Additives on Calories

The reason many teas become high in calories is due to what is added after brewing. Ingredients like sugar, honey, flavored syrups, and dairy dramatically increase the calorie count. Even a seemingly small addition can add up quickly over several cups a day. For instance, a single teaspoon of sugar can add 16 calories, while a tablespoon of honey can add 64 calories. Specialty drinks like chai lattes or bubble teas can contain hundreds of calories per serving due to sweetened condensed milk, heavy cream, and sugary syrups.

Benefits Beyond Zero Calories

Choosing zero-calorie teas offers several health advantages beyond just weight management. Many teas are rich in antioxidants that help combat oxidative stress and inflammation.

• Heart Health: The polyphenols and flavonoids found in teas like green and black tea can help improve heart health by regulating blood pressure and improving blood vessel function.
• Hydration: Tea is mostly water, making it a great, flavorful way to stay hydrated. Proper hydration is essential for regulating body temperature, transporting nutrients, and supporting overall bodily functions.
• Metabolism Boost: Green tea's catechins have been studied for their ability to enhance fat oxidation and increase energy expenditure.
