Green tea is made from Camellia sinensis, undergoing minimal oxidation during processing. Originally from China, green tea has been associated with many other countries in Asia such as Japan, South Korea and other Middle East countries. There are many available varieties of green tea in different countries where it is grown, wherein they differ in terms of growth conditions, processing, and harvesting time.
Green tea has been known to possess different health benefits, as there are several studies and claims that are suggestive that regular tea drinkers have a lower chance of experiencing heart disease, as well as developing certain types of cancer. Not only that, but green tea has been linked to weight loss, a fact which is supported by different studies.
The average fat oxidation rates from a study in Birmingham University were seventeen percent higher, after consuming green tea extract compared to consuming a placebo. Also, the contribution of fat oxidation to total energy expenditure was also significantly higher by a similar percentage after ingesting green tea extract, thus implying that green tea extracts do not only increase fat oxidation during exercise, but it also improves insulin sensitivity and glucose tolerance in young men.
Meanwhile, a study in Queen Margaret University in Edinburgh showed that short term consumption of commercial green tea reduces systolic and diastolic Blood Pressure, total cholesterol, body fat and body weight. So what causes these weight loss occurrences in the body? What is in green tea that does these things? The answer is quite simple, really. It is all in green tea caffeine.
Green tea caffeine works well in relation to weight loss and obesity management because it induces the process of thermogenesis, wherein the body produces body heat to slowly burn out the fats. Having at least six cups a day will allow green tea caffeine to actually increase thermogenesis at around 100 kilocalories a day. Green tea caffeine also stimulates fat oxidation, which is the body's process of burning fats and using them as energy.
Fat oxidation is not necessarily linked to the amount of fat consumed, wherein the body will have a positive balance of fat when there has been an excess consumption of energy sources, or even a restriction in physical activity. When the amount of carbohydrates you are consuming increases, there is a greater chance that the same carbohydrates you consumed will increase your available stores of fat. This will then decrease the amount of fat being oxidized, thus increasing the amount of available fat. However, when food energy is decreased or when your exercise levels are increased, fat oxidation will increase as well. This means that while a high level of carbohydrate intake does not always lead to increased fat stores, high intakes of fat will generally be reflected in the fat stored in the adipose tissues.
So there you have it. Aside from the health benefits that tea provides, green tea caffeine really does a lot for the health of a person. Greed tea caffeine does not only deal with fax oxidation but it also increases the levels of thermogenesis in a person. So, overall, green tea caffeine as well as green tea itself does help in cleansing the body.
