Oolong Tea and Weight Loss

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.”

Oolong Tea Health Benefits

Oolong tea is a semi-oxidised (semi fermented) tea that falls in between black and green teas. Wuyi Cliff Oolong tea from Fujian province, China is the most famous and expensive of all the Oolong tea varieties.

Oolong tea health benefits

Oolong tea is rich in polyphenols, much higher than that in green and black teas. Polyphenols are antioxidants that promote Oolong tea health benefits. They remove and minimise damage by free radicals in the body. Free radicals are unstable particles that damage cells. They are caused by lifestyle or environmental factors such as excessive stress, poor diet, smoking, pollution, chemicals in food, pesticides, too much exercise and radiation.

The body has enzymes to control certain amounts of free radicals. If the latter become excessive, they can cause damage to the body. This is why we need antioxidants like polyphenols to enhance the enzyme function and neutralise free radicals. Cellular damage by free radicals result in heart disease, cancer, ageing, diabetes, degenerative and autoimmune diseases.

The Chinese have long known about the weight loss potential of Oolong tea. They’ve been drinking it for thousand of years for health healing and obesity control.

Studies have found that:
-people who drank Wuyi Cliff Oolong tea burned more than TWICE calories than those who drank Japanese green tea.
- drinking Wuyi Cliff Oolong tea 15 mins before eating carbs reduces the insulin spike following the carb meal. High insulin levels are associated with body fat storage. By keeping insulin under control, Oolong tea reduces the fattening effects of carbohydrates.
- polyphenols in Oolong tea increases energy expenditure and fat burning by 35-45%.

Other health benefits of Oolong tea are:
- reduces cholesterol
- prevents heart diseases
- strengthens immune system
- improves digestion
- strengthens teeth and prevents cavities

Here are some studies on Oolong tea weight loss:

Thermogenic ingredients and body weight regulation

“Tools for obesity management, including consumption of caffeine, capsaicin and different teas such as green, white and oolong tea, have been proposed as strategies for weight loss and weight maintenance, as they may increase energy expenditure (4-5%), fat oxidation (10-16%) and have been proposed to counteract the decrease in metabolic rate that is present during weight loss. Daily increases in thermogenesis of approximately 300-400 kJ can eventually lead to substantial weight loss.”

Anti-obesity action of oolong tea

“The results suggest that oolong tea may be an effective crude drug for the treatment of obesity and fatty liver caused by a high-fat diet.”
