Does coffee make you gain weight?

Not likely: There's not many carbs or calories in a standard cup of coffee, and the caffeine may actually decrease appetite. Some gourmet coffee drinks have heavy cream, lots of sugar, or other sweet additives, and can therefore contain 250 calories or more.

The fancy ones do.: A regular cup of black coffee only has about ten calories. But you can accumulate several hundred calories in a latte or other fancy coffee drink, with all the heavy cream and whole milk and flavoring syrups. Stick to plain coffee with perhaps 2% milk or some flavored creamer - not a lot, just to taste.
