Does Acai Essence really work?

Ok i need people with personal experience for this one. Ive been looking for a way to lose weight but I don’t want to invest on anything that will end up being a waste of my time and money. I know there are websites, tv shows, and magazines that say it works, but then again there was also lots of advertising for Alli and that ended up not working at all. So, if anyone here has used the product give me your review. Should I buy it? yes/no/why? please and thank you!!!!
help? =] please?

Actually no Acai product is gong to help you lose weight. They are not appetite suppresants. One can only lose weight by expending more energy than the food one eats.
