Weight loss supplement "Acai" endorsed by Oprah?

I have been seeing and hearing about this supplement for weight loss called Acai. Apparently you mix it with your water/juice and you start loosing the pounds. (44 in 3 months was her example) I have done fad diets, used weight loss supplements, had meals delivered to my door and ordered weight loss programs from infomercials.These didn't work for long. NOTHING has worked better than the traditional diet and exercise and have recently lost 35 pounds already. So it seems that Oprah is endorsing this product called "Acai". You would think since Oprah is one of the most powerful women in America that she wouldn't put her name on something that wouldn't work, right? I mean, she doesn't need any more money! So you think it really works then??? I need to get rid of this dang little bit of tummy fat, and that's where it works, on your love handles. Hmmmm......
