Wu-Yi tea is well known for it's ability to help people lose weight. While it is commonly misconceived that it radically makes you lose weight simply by drinking it - like a magic pill - it still does help you lose weight successfully. Hundreds and thousands of people have used Wu-Yi tea and have successfully lost weight when doing so. But does it actually burn fat? Celebrities and even people in politics have used and promoted Wu-Yi oolong tea and the Wu-Yi diet. Many have testified for what it can do, losing ten, twenty, thirty or even more pounds of fat in a few weeks.
In some studies on Wu-Yi's weight loss abilities, Wu-Yi tea caused the participates to lose anywhere from ten to thirty pounds in a few months. While there isn't yet the data to back it up, those who participated in this study have claimed to have kept the fat of as well.
Therefore, I would have to personally concluded that yes, Wu-Yi tea does indeed help you burn fat. It doesn't do it on its own though, it should be used as a dietary supplement. That being said, it has been proven to help you lose weight by boosting your metabolism.
In conclusion, there are several studies that have been done that do indeed concluded that Wu-Yi tea and the Wu-Yi diet system do help you burn fat. However, there hasn't been any certified or official medical word on its fat burning abilities. You'll have to decide for yourself.
