Celsius energy drinks: do they do anything?

It is a bit misleading. On the can it says it burns 100 calories so people believe that, just by drinking it, they are burning 100 calories. But what it actually is supposed to do is raise your heart rate and help you burn more calories while exercising. But really, it's just an energy drink loaded with caffeine. I love them because they taste really good and are only 10 calories a serving. My favorite is the raspberry green tea.
