All teas are made from the same tea plant, Camellia Sinensis. The difference lies in their production methods.
Oolong tea (Wu Long Tea) is semi fermented tea. It comes somewhere in between green tea (unfermented) and black tea (fully fermented).
The production of Oolong tea is a complex process that requires great skill from tea masters. They have to know when to stop fermentation of tea leaves. The various Oolong tea varieties are due to different ranges of fermentation. Wuyi Cliff Oolong tea is one of the best and most expensive Oolong tea. It originates from Mount Wu Yi in Fujian Province, a region that is virtually free from pollution, with clean air and water.

Oolong tea is high in polyphenol, the antioxidant that promotes good health. See this post on –> Oolong tea health benefits.
There have been great interests from researchers on Oolong tea and weight loss. Studies on humans and animals have shown that Oolong tea can indeed help lose weight.
How does Oolong tea aid weight loss?
Polyphenols in Oolong tea have been shown promote weight loss by:
- boosting metabolism
- burning fat
- inhibiting fat absorption
In a study conducted by Aichi Medical University Institute and Nagoya City University in 2001 on 12 men and women to examine the effect of oolong tea on their health, 9 subjects reduced their waistline by 2cm and 8 subjects reduced their upper arms by 2cm. It is found that the polyphenols in Oolong tea activate lipase, the enzyme that dissolves body fat.
Here are some more studies on Oolong tea and weight loss and their findings:
Beneficial effects of oolong tea consumption on diet-induced overweight and obese subjects
“Oolong tea could decrease body fat content and reduce body weight through improving lipid metabolism. Chronic consumption of oolong tea may prevent against obesity.”
Oolong tea increases energy metabolism in Japanese females
“In comparison with green tea, oolong tea contained approximately half the caffeine and epigallocatechin galate, while polymerized polyphenols were double. These results suggest that oolong tea increases energy expenditure (EE) by its polymerized polyphenols.”
Oolong tea increases metabolic rate and fat oxidation in men
“Energy expenditure (EE) was significantly increased 2.9%… In addition, fat oxidation was significantly higher (12%) when subjects consumed the full-strength tea rather than water.”
