Before drinking coffee, you should pay attention to the following matters:

1, coffee with low-fat milk, no cream. Low-fat milk has less calories, which helps to offset the loss of calcium (a spoonful of low-fat milk has only 6 calories, but the calcium content is 19 mg).

Don't add sugar to coffee. Eating a lot of sweetened coffee every day will increase calories.
