How many calories are in tea?
A 250 ml mug of plain black tea, no milk and no sugar, is about 2 kcal. The leaves contribute almost nothing: every calorie people associate with tea is added after the brewing.
Per portion
| Portion | Calories | Protein | Carbs | Fat |
|---|---|---|---|---|
| Black tea, 250 ml, nothing added | ~2 kcal | 0 g | 0.5 g | 0 g |
| Tea + 30 ml (2 tbsp) semi-skimmed milk | ~16 kcal | 1 g | 1.5 g | 0.5 g |
| Tea + 50 ml whole milk | ~34 kcal | 1.7 g | 2.5 g | 1.8 g |
| Tea + 30 ml semi-skimmed + 1 tsp sugar | ~32 kcal | 1 g | 5.5 g | 0.5 g |
| Tea + 30 ml semi-skimmed + 2 tsp sugar | ~48 kcal | 1 g | 9.5 g | 0.5 g |
| Masala chai, 200 ml, half whole milk, 2 tsp sugar | ~95 kcal | 3.5 g | 14 g | 3.5 g |
| Chai latte, large (400 ml), shop-made with syrup | 220–300 kcal | 8–11 g | 40–50 g | 5–9 g |
| Bubble milk tea, 500 ml, with tapioca pearls | 300–450 kcal | 4–6 g | 60–85 g | 5–10 g |
What changes the number
Milk volume, which nobody measures. A “splash” is anywhere from 20 ml to 50 ml, a spread of about 15 kcal a cup. Trivial once; not six times.
Milk type. Per 100 ml: skimmed about 35 kcal, semi-skimmed about 48, whole about 64. Oat is 45–60 depending on whether it is the barista version, unsweetened almond 15–25. Moving six cups from whole to semi-skimmed saves roughly 50 kcal a day.
Sugar, about 16 kcal a level teaspoon and 24 heaped. Honey is about 21 kcal a teaspoon and jaggery much the same as sugar per gram; neither is lighter.
Condensed milk, used in Vietnamese and Hong Kong style milk tea, is about 320 kcal per 100 g, so one 25 g spoonful is 80 kcal.
Premix sachets. Instant chai and 3-in-1 powders run 60–110 kcal a sachet, mostly sugar, glucose syrup and vegetable fat. Read the per-sachet figure rather than the per-100 g column, as with any food label.
What does not change it: steeping time, a second teabag, loose leaf versus bags, black versus oolong. And if you arrived expecting tea to raise metabolism, that argument sits on the green tea page — real, measurable, far too small to matter.
Where it fits in a deficit
Plain tea is one of the few things you can drink freely without touching the arithmetic, and a hot drink genuinely helps bridge the gap between meals through warmth and habit rather than any real satiety.
Milky sweet tea behaves like any other liquid calorie: it does not reduce what you eat at the next meal in proportion to what it cost, the problem with drinkable energy. It still sits far below anything from a coffee shop.
The practical note: the ritual matters more than the drink. Halving two sugars to one saves 16 kcal a cup and most people stop noticing inside a week. Switching to a black tea you dislike tends to last four days.
The six-cups-a-day arithmetic
One cup of any of this is a rounding error. Six is not:
| Six cups a day of… | Daily | Weekly |
|---|---|---|
| Plain black tea | ~12 kcal | ~85 kcal |
| Tea with a splash of semi-skimmed | ~95 kcal | ~670 kcal |
| Tea with semi-skimmed and 1 sugar | ~190 kcal | ~1,350 kcal |
| Masala chai, half whole milk, 2 sugars | ~570 kcal | ~4,000 kcal |
Made richer, with 150 ml of milk in a 200 ml cup, chai is nearer 130 kcal, and six of those is about 770 kcal a day.
For scale, a deliberate calorie deficit is usually set at 400–600 kcal a day. A six-chai habit is the size of the whole deficit, and it hides because it never looks like eating.
Not an argument for giving up chai — an argument for counting it, and deciding what it comes out of.
