There is much interest in weight loss and oolong tea (a. KA Wulong tea) that we are going to look at research supporting the connection. Let’s start at the beginning, all tea comes from one plant Camellia Sinensis if it does not come from that installation is not tea (herbs come from a variety of plants). After some time, the plant protecting themselves from photosynthetic stressors by the formation of chemical compounds known as polyphenols. Polyphenols, which include flavonoids, have the same therapeutic class of compounds, antioxidants that fruits and vegetables good for you.
The difference in green tea and Oolong tea is processed. All tea is green when picked. Green tea is heated to the natural enzymatic reaction (oxidation) of the blade to stop. Once dried, green tea leaves are then rolled intentionally breaking the cell structure. Oolong tea leaves are plucked, kept under carefully controlled conditions and allowed to oxidize.
These leaves are not intentionally broken, while most of the cell structure intact. These differences make the processing of each category of tea beneficially different even though they come from the same plant. The weight loss connection The two main ways to reduce food related body weight are; increase energy expenditure (EE) and inhibit the absorption of nutrients, including fats and carbohydrates. Caffeine is a stimulant so it is generally accepted that the caffeine in tea increases metabolism, causing increased ee. So the question is, is it only the caffeine or other substances in the tea contributing to this increase? Research The Chinese have long believed that oolong tea is beneficial in reducing and maintaining weight.
A Chinese study in 1998 of 102 women showed that continuous consumption of oolong tea for six weeks resulted in a reduction of body weight. This study, along with the question of other compounds contributing to tea’s weight loss benefits, spurred further investigation. In 2001, physiologist Dr. William Rumpler, of our agricultural research services of diet and human laboratory, investigated the ancient Chinese belief that oolong tea is effective in controlling body weight. The study measured how tea energy expenditure (EE) influences and include 12 male volunteers were given 4 separate beverage formulas over three consecutive days.
The beverage formulas consisted of: 1) full strength oolong tea, 2) caffeinated water with caffeine equal to full strength oolong tea, 3) half strength oolong tea and 4) non caffeinated water. Participants ee was measured 24 hours and resulted in – Ee level of about 3% higher when they are either the full strength oolong tea or caffeinated water versus the non caffeinated drink water. – Participants burned an average of 67 more calories per day when drinking the full strength oolong tea. – Participants increased fat oxidation (fat burning) by a whooping 12% after consuming the full strength oolong tea compared to caffeinated water. – These data indicate that a component other than caffeine is responsible for promoting the preferential use of fat as an energy source.
The increase in fat oxidation in this study is great! Oolong tea can actually tell your body to burn fat for energy! Scientists then speculated that caffeine combined with egcgs worked together to increase fat oxidation. A Japanese study conducted in 2003, went one step further the benefits of Oolong tea and green tea to compare weight reduction. Eleven healthy young female students participated in this well-controlled study. Participants received three different beverage formulas: 1) oolong tea, 2) powdered green tea leaves and 3) water. Both tea were prepared by boiling water.
The oolong tea steeped for five minutes and the powdered green tea leaves were dissolved. After measurements were taken, the results determined – Oolong tea had higher EE levels from beginning to end and at intervals of 30, 60, 90 and 120 minutes. – Ee levels peak at 90 minutes for both oolong and green tea and remained at their respective levels until 120 minutes. – These results indicate that after consuming oolong tea you consume more energy than if you go green tea or water and that it may take up to two hours. The concentrations of caffeine, individual catechins and other polyphenols were also measured producing these interesting findings – The caffeine and EGCG content was much higher in the green tea versus the oolong tea.
- The concentration of polymerized polyphenols was significantly higher in the oolong tea compared with the green tea. These findings show that it’s the polymerized polyphenols, highest in oolong tea, that link tea to burn fat, not just the caffeine or just the combination of caffeine and egcgs. Moreover, the rest of the compounds were compared in the tea was similar to or equivalent to each other with no noticeable differences, the strengthening of the results. We have shown that a significant ee Oolong tea increases one by as much as 120 minutes, and may even promote the preferential use of fats as an energy source which makes it a healthy instrument for reducing and maintaining weight. So what about the absorption of nutrients? Oolong tea effect on blocking the absorption of fats and carbohydrates are thought to play an important role in reducing the weight advantages.
Although more research must be done, initial studies indicate that oolong tea has absorption blocking potential. There are proven methods to lose weight and keep it off, exercise, get enough sleep and eating a balanced diet. Oolong tea can enhance these positive changes and garner faster results. Let’s face it – Oolong tea is not a quick fix despite the recent advertising claims by slick marketing “professionals. -Oolong tea need not be expensive to be effective.
