Wu long tea (also known as Oolong tea) has been gaining popularity and a reputation for being an amazing fat burner.

Web sites proclaim it to be the "world's most powerful fat burner", Fit Smart Capsules Stiftung Warentest and even market it as a "slimming tea." Wu long tea contains only half as much EGCG as green tea, but instead is higher in polymerized polyphenols, which may contribute to its fat burning properties.
