A cup of coffee with the addition of milk contains around 20 to 30 calories per cup of coffee with the milk.
The actual amount of calories your cup of coffee contains with the milk depends on how much milk you add to the coffee and what size of coffee cup you have.
The more coffee and more milk the more calories the cup of coffee contains.
A cup of coffee with creamer added is around 20 calories.
The average cup of coffee without creamer or milk has around 10 to 12 calories depending on the size of the coffee cup.
Coffee is healthiest when it's consumed without the addition of milk or creamer but it's still okay to drink coffee with creamer or milk.
Even when you're working on losing weight you can still drink some coffee with creamer or milk.
Just don't add too much creamer or too much milk to the coffee or you add even more calories.
A latte contains more calories than a regular cup of coffee with creamer or milk though.
I prefer my coffee with creamer because it makes the coffee taste much better but I'll drink black coffee once in awhile.
