What does that mean?  Grean tea burns fat.

You might recall this episode of Oprah where Dr Perricone (Author of The Perricone Promise) talks about how grean tea could help you lose 10 pounds in 6 weeks.

Oprah: Now I’ve read in your book that you said if I just replaced coffee with green tea instead, that I could lose 10 pounds in six weeks.Dr. Perricone: Absolutely.

Oprah: Now really. How could that — what is the big deal about this?

Dr Perricone: Coffee has organic acids that raise your blood sugar, raise insulin. Insulin puts a lock on body fat. When you switch over to green tea, you get your caffeine, you’re all set, but you will drop your insulin levels and body fat will fall very rapidly. So 10 pounds in six weeks, I will guarantee it.

Oprah: I’m gonna do that. OK. That is so good! Whoo! That is great.
