How Does Green Tea Help Weight Loss?

For many people, finding best weight loss supplements safe and effective would be nothing short of a miracle. We all know that there is no magic bullet when it comes to weight loss, we must consume fewer calories in a day than our body uses to lose weight. However, finding ways to burn fat faster would speed up the process and make it easier.

One product that seems to have a lot of promise in helping people to lose weight are green tea. In some studies, green tea has been shown to help regulate insulin and lower cholesterol and triglycerides. In addition, it was believed that green tea speed up metabolism, so that we burn fat faster, and can even turn off the receptors that make us want to eat.

In addition, green tea, unlike many weight loss aids is very healthy overall. Green tea is a potential source of anti-oxidants, which help us stay healthy and free from disease by fighting free radicals. Free radicals are molecules containing oxygen that is a byproduct of our digestive process. Left unchecked, they damage cells and DNA, eventually leading to disease.

However, green tea and other foods with anti-oxidants keep free radicals at bay, preventing aging and disease. For example, a diet rich in green tea and other antioxidants have been associated with reduced risk of heart disease and cancer. Thus, green tea is a best weight loss supplements that you can feel comfortable, because it can improve overall health while it helps you let go of pounds.

Most of us are aware of the problem that many weight loss supplements can cause. Ephedra, for example, has proven to be an effective way to speed up the metabolism, but can have side effects that are dangerous. In fact, even been linked to heart attacks and death in some users.

But, just how green tea work? There are several components in green tea that seem to work together to provide health and weight loss benefits of green tea is very popular. Researchers have pointed to three components in green tea that seem to have an effective weight loss.


Green tea contain less caffeine than coffee or black tea, but it does not contain caffeine. Interestingly enough, however, caffeine, green tea appeared to have no negative side effects found in other products that contain caffeine. Green tea does not cause discomfort or accelerated heart rate in a way that other caffeinated beverages can. However, caffeine in green tea does not appear to speed up the metabolism.

Many of us take for granted your intake of caffeine, but caffeine has been shown to help weight loss. Many studies have shown that people on low-calorie diet who consume caffeine every day as a whole lost more weight than those who are on low-calorie diet.


Catechins are anti-oxidants in green tea. Polyphenolic antioxidant catechins are plant metabolites, specifically flavonoids called flavan-3-OLS. They are found in many plants, including cocoa plants and crops of coffee, but the best source of catechins is the Camellia sinensis (tea) plant.

The reason that green tea is considered a better source of catechins than black tea is because of differences in processing. Black tea is fermented, which changes catechins. Green tea, however, is unfermented, leaving the catechins in their natural state.

Because tea catechins are some of the most powerful anti-oxidants around, they are some of the most effective way to prevent disease. This is why diets rich in tea are considered to prevent various diseases, including heart disease and cancer.

In terms of weight loss, catechin is believed to suppress lipid (fat) absorption from food. This is important because it helps lower cholesterol, but also thought to prevent the accumulation of body fat.


Theanine is the main amino acid in green tea. Theanine may be important for weight loss because of its ability to stimulate relaxation and release of dopamine. Dopamine is a chemical produced by the brain that assist in providing welfare feelings in the body.

Theanine also seems to minimize the effects of caffeine, which explains why the caffeine in green tea does not seem to cause anxiety and increased heart rate in a way that caffeine in other beverages can. So, while theanine may not actively cause weight loss, can be effective in creating a sense of calm in people who swallowed it. This strength can help those who eat too much as a result of the stress to stop this trend.

It is certain that more study is needed on how green tea helps you lose weight. One interesting study on the subject, by the University of Shizuoka in Japan, evaluated the three components of green tea as an individual, or a combination, to try and determine what components are most important.

The study concludes that the most important component of green tea for weight loss is caffeine. Caffeine is responsible for accelerating the metabolism and creating thermogenesis, which burns fat. However, research also showed that catechins do seem to have an anti-obesity effect on their own, helping the body to remove fat from foods rather than absorb it.

In short, green tea seems to be close to a perfect combination for helping lose weight and improve health at the same time. Diet and exercise are still important to remove excess weight and keeping it away for good, but it does not appear that green tea can be an effective tool in fighting the battle of the bulge.
