Weight Loss Anyone?

My friend the other day was talking about this hoodia product that she uses to help lose weight. it's supposed to act as a appetite suppressant, and help you lose weight. She feels like it works, and I'm curious to see how long her results will last. I've heard about it in the news, people these days are using it more and more to help them lose weight, I think it'd more natural than some extreme ways of losing weight, like stapling your stomach or what not.
