Coke's Idea of a Calorie Killer

The Wall Street Journal had some interesting questions about the usefulness of Coca-Cola's latest beverage, Enviga, a green-tea based concoction that promises to help consumers burn calories. The company told Journal reporters that three 12-ounce cans of Enviga over a 24-hour period would help a healthy person of normal weight burn anywhere from 60 to 100 additional calories. OK. that sounds good. So how many can's of Enviga would it take to counteract the caloric effect of say, a Big Mac, or a can of Coke?
