Can you tell me how many bottles of green tea does it take to boost metabolism?

Not sure it does...: Like so many alternative treatments or products, tradition, theory, hope and anecdotal evidence do not hold up when a formal review of evidence is done. See the excellent answers on weight loss on this site and drink tea because you like it, not for its supposed magical properties. More info: http://nccam.Nih.Gov/health/greentea?Nav=gsa.
