How Many Calories are in Your Coffee?

I read this article that suggests some coffee sold by high street chain can contain a third of the recommended daily calorie intake. The article highlights coffee such as Starbucks large white chocolate mocha which contains 628 calories. In comparison a medium mocha with whipped cream from Caffe Nero contains 326 calories and a medium mocha flake from Costa Coffee contains 297 calories. Whilst this may seem a lot, all of these coffee brands contain whole milk, chocolate and cream so personally I would expect them to have a high calorie content.
