Obesity has become one of the major health
issues in our society today. More than half of the American population is
overweight or obese. As a result, diet and weight loss plans have become
increasingly popular. But not all diet plans work. And not all of them are
necessarily risk-free. A safer alternative for people wanting to lose weight
are green tea diets.
About Green Tea
For thousands of years, green tea diet has
been highly valued by the Chinese as an herbal and medicinal drink. It was
believed that green tea diet was first discovered by the Chinese Emperor Shen
Nung who was boiling water when the leaves of a nearby tree fell into his pot.
The result was the first ever pot of green tea.
Like all three of the major Asian teas in the market, green tea comes from the plant called Carmellia sinensis. Much of the health benefits of green tea diets owe to the steaming method of making it. As opposed to black and oolong tea which undergoes full oxidization, green tea diet is only gently steamed, preserving the natural antioxidants in its original form.

The Health Benefits of Green Tea Diet
There are many health benefits associated
with having a green tea diet. One of these green tea diet benefits is
preventing cancer. Certain substances present in green tea diets are said to
help in destroying cancer cells without harming any neighboring tissues. This
substance in green tea diets is called epigallocatechin gallate or EGCG.
EGCG
in green tea diets is also helpful in increasing the 24-hour energy expenditure
of the body. A study on green tea diets conducted by American and Swiss
scientists in the University
of Geneva showed an
additional increase of four percent in the body’s natural energy expenditure.
People who were on a green tea diet were more likely to use up more fats than
those not on a green tea diet.
Also, green tea diets are said to greatly
help in lowering down cholesterol levels in humans. The study on green tea
diets was conducted in China
using 240 people with high cholesterol levels as subjects. These people were
placed on a green tea diet of one capsule (equivalent to seven cups of green
tea) or were given one placebo every day. After twelve weeks, those who were on
a green tea diet dropped sixteen percent in their cholesterol levels.
Green
tea diets can also be a potential cure to obesity. The catechin polyphenols
present in green tea diets can delay the reaction of gastric and pancreatic
lipases in the body. These enzymes are responsible for converting calories in
the body into fats. By delaying these enzymes, green tea diets can therefore stop
fat from being stored and prevent obesity in people.
Green
tea diets contain substantial amount of caffeine that make it a mild
appetite-suppressant. However, caffeine content in green tea diets is not as
high as those found in other caffeine-based beverages, like coffee. Caffeine
may be harmful for the body since an excess of it can cause heart palpitations,
hypertension, and insomnia. Because green tea diets contain only very low
levels of caffeine, there is no danger of experiencing these side-effects.
