Variations
Green tea
About 1 calorie per 100g — essentially identical to black tea in calories. Less caffeine (~12mg vs ~20mg per 100g). Higher in catechins (EGCG), powerful antioxidants studied for metabolic benefits. Milder, slightly grassy flavor. Both are excellent zero-calorie beverage choices.
Tea with milk
About 15 calories per 100g with a splash of whole milk. A cup of tea with 30ml milk has about 20 kcal — 10x more than black tea alone, but still very low-calorie. The milk adds protein (0.5g) and calcium. For fewer calories, use skim milk (~10 kcal per splash) or plant milk.
Tea with sugar
About 20 calories per 100g with 1 teaspoon of sugar per cup. One teaspoon of sugar adds 16 kcal and 4g of carbs. Two teaspoons doubles it to 32 kcal added. Sweet tea (popular in the US South) can have 80-100 kcal per cup with 20-25g sugar. If trying to lose weight, gradually reduce sugar or switch to plain tea.
Frequently Asked Questions
How many calories are in tea?
One cup of brewed black tea (237g) has approximately 2 calories. Per 100g, black tea has just 1 calorie — virtually zero. The trace calories come from minimal carbohydrates (0.3g per 100g). Plain black tea is one of the lowest-calorie beverages you can drink, alongside water and black coffee.
How much caffeine is in tea?
Black tea has about 20mg of caffeine per 100g, which means one cup (237g) contains approximately 47mg of caffeine. That is about half the caffeine in a cup of coffee (~95mg). Caffeine content varies by brewing time and tea variety — longer steeping extracts more caffeine. Decaf black tea has about 2mg per cup.
Black tea vs green tea — what is the difference?
Both come from the same plant (Camellia sinensis). Black tea: ~1 kcal/100g, ~20mg caffeine/100g, fully oxidized, stronger flavor. Green tea: ~1 kcal/100g, ~12mg caffeine/100g, minimally oxidized, milder flavor. Green tea is higher in catechins (antioxidants), while black tea has more theaflavins. Both are essentially zero-calorie and healthy choices.
How many calories does tea with milk have?
Plain black tea has just 2 kcal per cup. Adding a splash of whole milk (30ml) adds about 18 kcal for a total of ~20 kcal. A full British-style tea with 60ml milk has about 38 kcal. With sugar (1 teaspoon) add another 16 kcal. A chai latte with milk can reach 150-200 kcal. Keep tea plain or with minimal milk for the lowest calories.
How much fluoride is in tea?
Black tea has 373mcg of fluoride per 100g — one of the highest natural food sources. One cup (237g) provides about 884mcg. Fluoride supports dental health by strengthening tooth enamel and reducing cavity risk. The tea plant (Camellia sinensis) accumulates fluoride from soil. Excessive consumption (6+ cups daily) may contribute to excess fluoride intake.
Is tea good for weight loss?
Black tea is an excellent beverage for weight loss. At virtually zero calories, it adds nothing to your daily intake when consumed plain. The caffeine (47mg per cup) may slightly boost metabolism and fat oxidation. Tea also provides hydration and can replace higher-calorie drinks. Studies suggest tea polyphenols may support gut health and metabolism. Just avoid adding sugar, honey, or excessive milk.
