Plain Tea: A Negligible Calorie Beverage
Plain tea, whether sourced from the Camellia sinensis plant or brewed as an herbal infusion, is primarily water and contains a negligible number of calories. The leaves themselves contribute only trace amounts of carbohydrates and protein that translate to 0-2 calories per 8-ounce cup. This is true for green, black, white, and oolong varieties, and the same holds for herbal teas, or tisanes, made from brewing flowers, herbs, and spices.
The significant increase in a tea's caloric value comes from popular additives. For instance, a single teaspoon of sugar adds about 16 calories, while a tablespoon of honey can add around 64 calories. The type of milk also makes a difference, with whole milk adding more calories than skimmed or plant-based alternatives. Choosing to drink tea plain is the single most effective way to ensure it remains a zero-calorie drink.
The Least Calorie Teas: A Breakdown
When prepared without milk, sugar, or other sweeteners, all traditional teas are incredibly low in calories. The differences are minimal and often negligible for those monitoring their intake.
Green Tea
Unoxidized and minimally processed, green tea is a classic low-calorie choice. An 8-ounce cup of plain green tea contains approximately 2 calories, along with potent antioxidants like epigallocatechin gallate (EGCG). The health benefits associated with green tea, such as boosting metabolism, are often attributed to its antioxidant properties, making it a popular choice for health-conscious individuals.
Black Tea
Black tea leaves are fully oxidized, giving them a richer flavor and darker color. Despite the difference in processing, a plain 8-ounce cup of black tea also contains roughly 2 calories. The antioxidants in black tea, such as theaflavins and thearubigins, differ from those in green tea but still offer beneficial properties. When consumed unsweetened, it is an excellent low-calorie option.
White Tea
Regarded as the least processed of all traditional teas, white tea is harvested from young tea buds. Its delicate flavor comes with a similarly low-calorie profile, containing only about 2 calories per cup when brewed plain. Its minimal processing means it retains a high level of antioxidants, potentially offering more health benefits per serving.
Oolong Tea
Oolong tea falls between green and black tea in terms of oxidation. This partial fermentation process results in a complex flavor profile while maintaining a very low-calorie count, approximately 2 calories per 8-ounce serving. Its unique composition means it contains a mix of polyphenols found in both green and black tea.
Herbal Teas (Tisanes)
Herbal teas are infusions made from various plant parts, not from the Camellia sinensis plant. Most herbal teas, including chamomile, peppermint, and rooibos, contain 0-3 calories per cup, making them virtually calorie-free. Some varieties made with dried fruit may have slightly more, but the count remains very low and insignificant. Many herbal teas are naturally caffeine-free, offering a soothing, low-calorie alternative.

How to Enjoy Low-Calorie Tea
Making your tea low-calorie is simple if you follow a few guidelines. Control is key, and brewing your own tea at home is the best way to manage ingredients.
- Brew it plain: The simplest method is to drink your tea without any additions. This allows you to experience the natural flavor of the leaves and ensure a truly zero-calorie beverage.
- Consider low-calorie sweeteners: If you prefer a touch of sweetness, opt for natural, low-calorie sweeteners like stevia or monk fruit extract instead of sugar or honey.
- Use milk alternatives wisely: Instead of whole milk, which can add significant calories, choose unsweetened skim milk, almond milk, or soy milk. The fewer additives in the milk alternative, the lower the calorie count will be.
- Flavor with natural, calorie-free additions: Add a squeeze of lemon, a few slices of fresh ginger, a cinnamon stick, or a sprig of mint for a flavor boost without any added calories.
- Beware of pre-sweetened drinks: Always check the label on bottled or pre-packaged teas, as many contain high amounts of added sugar. Making your own iced tea at home with plain brewed tea is a much healthier option.
What to Avoid: High-Calorie Tea Drinks
While plain teas are excellent for calorie-conscious consumers, many popular tea-based drinks found in coffee shops and grocery stores are laden with calories. These typically include:
- Bubble Tea (Boba): This popular drink can contain hundreds of calories due to ingredients like tapioca pearls, sweetened condensed milk, and flavored syrups.
- Chai Lattes: Often made with whole milk and heavily sweetened syrups, a single chai latte can contain 200 or more calories depending on the serving size and ingredients.
- Sweet Tea: A common staple, especially as iced tea, that is heavily sweetened with sugar during preparation. A single serving can add a substantial amount of empty calories to your day.
- Instant Tea Powders: These products often contain large amounts of added sugar and very little actual tea extract, making them a high-calorie choice.
For weight management and overall health, these sugary tea drinks should be viewed as occasional treats rather than daily beverages.
The Health Benefits of Low-Calorie Tea
Beyond calorie control, choosing plain, unsweetened tea offers numerous health advantages. The antioxidant compounds found in tea, such as polyphenols and catechins, are associated with several health benefits, including a reduced risk of cardiovascular disease, improved immune function, and potential cognitive benefits.
Additionally, replacing high-calorie sodas or sweetened juices with low-calorie tea can contribute significantly to weight loss goals by reducing overall daily calorie intake. Drinking tea can also contribute to daily hydration, which is vital for many bodily functions.
Conclusion: The Final Verdict on Low-Calorie Tea
To answer the question of what type of tea has the least calories, the simple and correct answer is any type of plain, unsweetened tea. Whether you prefer a robust black tea, a delicate white tea, or a calming herbal blend, the calorie count will remain negligible as long as you avoid adding sugar, honey, cream, or other high-calorie ingredients. For anyone aiming to manage their weight or reduce their sugar intake, embracing the simple pleasure of plain brewed tea is a healthy and effective strategy.
