Green tea is well known for its health benefits. The Chinese have been using it for the last 4000 years to treat everything from headaches to depression.
Today, there are many clinical studies providing evidence for healt benefits from drinking green tea. It is known that green tea reduces cholesterol, improves the ratio of good to bad cholesterol, reduces the risk of more than one type of cancer etc.

Recent studies have shown that green tea can also help reduce weight and bodyfat. A study reported on in the American Journal of Clinical Nutrition, found that green tea extract resulted in a significant increase in energy expenditure.Over a 24-hour period green tea extract increases the metabolic rate by 4%.
Other studies have shown that catechins in green tea help to inhibit the movement of glucose into fat cells. Green tea may also act as a glucose regulator.In other words it helps to slow the rise in blood sugar after a meal. This prevents high insulin spikes and the fat storage.
Green tea also helps in reducing the appetite.This may have something to do with the blood sugar regulating effects of green tea.
