Oolong tea alone does however have unique effects against obesity and cardiovascular disease. An article in Diabetes Research and Clinical Practice 65 (2004) by researchers in Japan showed that Oolong increased Adiponectin levels in patients with type 2 diabetes mellitus and coronary artery diesase. While water consuming groups showed no changes in adiponectin levels, a protein that is lowered in those with morose obesity, Coronary Artery disease, and Diabetes Mellitus, those who consumed Oolong showed a significant difference in blood levels of adiponectin.
It is suggested by numerous studies that this tea can be an aid in fat-loss. Oolong tea contains powerful anti-oxidant "Polyphenols", and "Flavanoids which are believed to have a role in activating the enzymes in the body that break down body fat. In addition, olong is known to raise body fat metabolism in rats by switching their bodies mechanisms to survive on Essential Fatty Acids rather than sugar. Oolong also suppresses the appetite while moderating blood sugar levels so that you can begin to kick the sugar habit without enduring the mood swings this often brings. However, any claims about the exact ability of Oolong tea to be a weight-loss aid have not been evaluated by the FDA.
