Does Acai Berry Help with Weight Loss?

I have been reading a lot of late about the fantastic anti-oxidant power of this acai berry. Have also read that it is very good for weight loss. Has anyone tried this for this purpose, did it work and did you use it alone or with a colon cleanse? Some articles I have read suggest that is has colon cleansing properties and others seem to suggest that the two need to be used in conjunction with each other. I would be very interested in anyone's personal experiences. Looking forward to feedback. Thanks.
