Coca-Cola and Nestle's new weight-loss drink Enviga enjoyed a limited release recently in New York, New Jersey, and Pennsylvania. The celebration appeared to be short-lived, however, as Connecticut Attorney General Richard Blumenthal began an investigation this week into claims that the product can promote weight loss.

Enviga contains a green tea extract known as EGCG, as well as caffeine and calcium. Coke cites studies that found that the combination of EGCG and caffeine speed up a person's metabolism, and a study done by Nestle found that young people who downed three of the drinks a day burned over 100 calories. Blumenthal says that the product is nothing more than "voodoo nutrition" and requested copies of all data collected by the corporation.

The product is slated for national release later this year, so we'll see who comes out on top. In the meantime, I have a question. If you have to guzzle three of these drinks to burn 100 calories, wouldn't it just be easier to take a 10 minute walk? Just my two cents...what do you think?
