1 cup (medium) of Filter coffee (unsweetened, no milk) (240 g) has 2 calories. That works out to 1 calories per 100 g. It contains 0.5 g of carbs, 0.2 g of protein, 0 g of fat and 0 g of fiber. Its 0.7 mg of B3 covers 5% of the Daily Value. Its glycemic index is 0 (low), so it raises blood sugar slowly.
Filter coffee (unsweetened, no milk) is made by pouring hot water through ground coffee held in a paper or reusable filter. Unlike espresso, it is brewed rather than forced through the grounds under pressure, and the finished cup is clear of sediment. It is common at home, in cafés and at breakfast tables across many coffee-drinking countries.
Its flavour can be delicate and fruity or fuller and gently bitter, depending on the beans and brew. Drink it on its own, or pair it with breakfast, a biscuit or a piece of chocolate. Without milk or sugar, it contributes very little energy while providing caffeine. If you prefer a milder cup, try a lighter roast or brew it for less time; decaffeinated beans are another option later in the day.

Low
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.

The caffeine in unsweetened, milk-free filter coffee varies with the beans, grind, coffee-to-water ratio and brewing time. A larger or stronger mug can contain more caffeine, so the number of cups alone does not tell you exactly how much you have had.
Yes, the caffeine in unsweetened, milk-free filter coffee can increase alertness and make it harder to fall asleep. If you are sensitive to caffeine, drinking it later in the day may disrupt your sleep; having your last cup earlier can help.
Generally, yes: paper-filtered unsweetened, milk-free filter coffee retains more of the coffee oils cafestol and kahweol than French press coffee does. Those oils can raise LDL cholesterol, so paper-filtered coffee is a useful choice if you are limiting them.
No, unsweetened, milk-free filter coffee does not usually dehydrate people who drink it regularly. It contributes fluid, although caffeine can have a mild diuretic effect, particularly for someone who does not usually consume it.
Yes, you can drink unsweetened, milk-free filter coffee on an empty stomach, but it can trigger heartburn, nausea or stomach discomfort in some people. If that happens, try having it with food or choosing a smaller cup.
Yes, many people can drink unsweetened, milk-free filter coffee during pregnancy, but its caffeine counts toward the daily limit recommended during pregnancy. Caffeine content varies by brew, so ask your prenatal care provider what limit is appropriate for you.
Unsweetened, milk-free filter coffee can taste bitter when it is over-extracted, often because the grounds are too fine or the water stays in contact with them too long. Try a coarser grind or a shorter brew, and avoid pouring freshly boiling water directly onto the grounds.
A medium grind usually works well for unsweetened, milk-free filter coffee. Grounds that are too fine can slow the water and produce a harsh cup, while grounds that are too coarse may let water pass through quickly and leave the coffee weak.
Yes, you can reheat unsweetened, milk-free filter coffee, but heating it again can make its flavor harsher and less aromatic. Warm it gently rather than boiling it; for the best taste, brew a fresh cup instead.
No, unsweetened, milk-free filter coffee does not by itself cause weight loss. Caffeine may briefly increase alertness, but drinking coffee does not produce lasting fat loss, and it should not replace meals as a weight-loss strategy.
