Can a Obese person Lose Weight With Beginners Ballet?

My girlfriend has tried all sorts to lose weight but nothing has worked nearly as well as the wu yi tea that she drinks, it's been covered on CNN and Fox News. She lost 6 pounds in three weeks. She gets it off a colleague at work but I discovered this site in Google; www.newloseweight.com - they have a free trial on at the moment, maybe they're worth a try?
