Green tea calories come to 2 for one 245 g cup of brewed, unsweetened tea, and 1 per 100 g. The number to notice is not on the brewed cup at all: a sweetened bottle of 270 g carries 73 calories and 14.4 g of sugar, so what you buy matters far more than how much you drink.

Five cups of green tea still add up to 12 calories
A plain cup of brewed green tea, 245 g, holds 2 calories. That is 0% of a 2000-calorie daily value, and the label rounds it there for good reason. Two cups come to 5 calories, three cups to 7, and five cups, 1,225 g of liquid, reach just 12. You would need a very long afternoon to make green tea a real line in your food log.
Volume barely moves the total because each 100 g has 1 calorie. Protein follows the same flat line: 0.5 g in one cup, 1.1 g in two, 2.7 g in five. Sodium stays tiny as well, 2 mg per cup and 12 mg across five cups, against a daily value of 2300 mg.
So portion size is the wrong lever to worry about. If you drink green tea plain, refill freely. What actually changes the count is whatever gets added to the cup or the bottle, and that is where the rest of this guide looks.
Every calorie in brewed green tea is protein, and there are barely any
The calorie split for brewed green tea reads 100% protein, 0% carbs and 0% fat. That sounds impressive until you see the scale: 0.2 g of protein per 100 g, and 0.5 g in a full cup. It is a rounding effect on a tiny number, not a protein source.
Carbs, fat, saturated fat, fiber, sugar and cholesterol all sit at 0 per 100 g in the USDA row Beverages, tea, green, brewed, regular. Potassium is the only mineral with a visible figure, 8 mg per 100 g, still small against a daily value of 4700 mg. Sodium is 1 mg per 100 g.
The practical reading is simple. From a calorie standpoint, brewed green tea is flavored water. Its place in your day is as a drink that stands in for something with more calories, not as a source of nutrients you need to track.
The sweetened bottle is the row to watch
Bottled green tea comes in two very different forms. A sweetened bottle of 270 g carries 73 calories, 16.7 g of carbs and 14.4 g of sugar, plus 0.6 g of fat. That is 4% of the daily calorie value in a drink many people never think of as food.
Sodium climbs too. The sweetened bottle lists 57 mg, or 2% of the daily value, against 2 mg for a brewed cup. An unsweetened bottle of 473 g sits at 0 calories and 0 g of sugar, with 33 mg of sodium, or 1% of the daily value.
The lesson: read the label before trusting the word green. Sweetened bottled teas such as Arizona Green Tea With Ginseng and Honey belong with sugary drinks, not with brewed tea. If you want bottle convenience without the sugar, the unsweetened version keeps the numbers at brewed-cup levels.
Plain green tea fits almost any day of eating
Because a cup is 2 calories, plain green tea leaves your daily total untouched. That makes it useful wherever a sweeter drink would otherwise go: with a meal, in the middle of the afternoon, or after dinner. Next to sweet tea at 32 calories per 100 g, the plain brew is an easy swap.
Additions are what count. Honey, sugar or milk turn the cup into a different food, and they deserve their own entry in your log. If you like it sweeter, try lemon, mint or fresh ginger for flavor first, and add sweetener only if you still want it.
Logging is quick either way. BodyPal can log green tea from a photo, and the entry for a plain cup will barely register. Spend your tracking attention on the food you eat alongside it instead.
How does green tea compare?
Here is brewed green tea next to kombucha tea and sweet tea, per 100 g and per usual serving.
Verdict: For the fewest calories pick plain green tea, at 1 per 100 g against 16 for kombucha tea and 32 for sweet tea. If you want a little sweetness, kombucha tea with 4 g of carbs per 100 g costs half the calories of sweet tea at 7.9 g.

Bottled green tea is sweetened, so its label calories sit far above plain brewed tea, and the drink mix is measured as dry powder rather than as a finished drink. Source: manufacturer labels / USDA FoodData Central.
