Did you know that there are different types of teas? And their properties and effects on our health and welfare are not the same?

Today in the market there are three main types of tea: green tea, black and oolong or “brown tea”. Its color is due to the oxidation process (also called fermentation).

For example, green tea is steamed, either baked or pan, and thereby prevents total oxidation and leaves remain green. Oolong tea is partially fermented. It means that in this case oxidation is also cut its leaves being partially black but only at the edges. Finally is the black tea which is fermented completely so that its leaves are absolutely black.

But in this article we refer to green tea. Today, green tea is a subject of study by many scientists because it has been found to help weight loss, among other beneficial effects on health.

Green tea was associated with an ancient Eastern practice only. But it has also proven to be a powerful weapon to combat obesity.

Several studies showed those who drank green tea three times daily had a 4% increase in daily energy expenditure. And without increasing the heart rate of these people.

Therefore it is considered as a better choice than any drug for weight loss, as these can cause adverse cardiac effects, especially in individuals suffering severe obesity, suffering from hypertension and other cardiovascular complications.

Although it was known as a great antioxidant, green tea extract helps eliminate. This is not due to small amounts of caffeine found in tea, since the subjects who received similar amounts of caffeine to those found in green tea exhibited no change in daily energy loss.

Experts explain that there are two ways to lose weight: one is reducing what is consumed (ie dieting) and the other by increasing energy expenditure (may be doing exercises). Green tea acts like the second mode, although the mechanisms involved are still poorly understood.

The researchers noted that green tea extract contains a high amount of polyphenols. These compounds may work together with other substances by increasing levels of oxidation and thermogenesis, for the body to “burn” the excess fat.

These studies highlight the following positive aspects of green tea:

· Not increase heart rate

. Stimulates thermogenesis and fat oxidation

. Produce a significant increase (4%) in daily energy expenditure.
