Green Tea Weight Loss
Ten Scientific Facts To Know
In the Green Tea Diet article, I cover many practical aspects of drinking green tea to lose weight. It should answer many of the questions you have, such as:
- Which tea to drink?
- How many cups a day?
- Best time for drinking?
This article covers the science aspect i.e. important facts you must know about green tea weight loss.
Are you ready to go?
During spring 2007, my friend and customer Ellen told me that drinking green tea has helped her shed 25 pounds in 6 months.
Although I have drunk green tea for many years, and am aware of its slimming effect, I still can't helped being impressed. You can read how she did it here.
Doesn’t that sound too easy? Or was it just a one off success? I was skeptical at first. So I delved into it, reading all the scientific studies that I could lay my hands on.
Here are my findings. Enjoy.
Green Tea Weight Loss Fact #1:
"Drinking tea for a long time makes one thin," says ancient Chinese medicinal classic Bencao Shiyi. Fast forward 1,300 years, and that is exactly what scientists have found today.
For those of you who are skeptical, I highly recommend you read Swen Wolfram's excellent review paper Anti-obesity effects of green tea.
In his peer review of 74 studies, he concluded that weight loss due to green tea consumption has been demonstrated in laboratory studies involving cell culture and animals. According to Dr. Wolfram, 9 human studies have been conducted, with "most of these studies reporting decreased body weight and fat mass."
There is still a need for well-designed human studies to better understand the underlying mechanisms, but there is no question that it works!
Green Tea Weight Loss Fact #2:
Why Do Most Diets Fail?
What is wrong with conventional dieting?
When you go on a diet and starve, your body's survival instinct is triggered and you automatically go on "energy saving" mode. This reduces your metabolism and makes you burn fewer calories.
In addition, your body begins to feed on itself. Although some fat may be used as energy, the most readily available source is protein i.e. muscle.
According to studies conducted by the University of Pennsylvania and elsewhere, the real problem starts after the dieting period, because this slowed metabolism can continue for up to weeks afterwards.
This causes the familiar yo-yo phenomenon, where you not only regain the lost weight, but rebound to even higher weight than what you started with.
You may see your weight going down on a scale, but actually you are losing muscle, not fat.
Your natural metabolism rate is largely determined by the amount of muscle you carry. Most diets fail because they help you lose the wrong kind of weight!
Green Tea Weight Loss Fact #3:
Why Does A Green Tea Diet Work?
Green tea weight loss works because it does not require you to eat a very low calorie diet.
Scientific studies have discovered that the main ingredients responsible for green tea slimming effects are caffeine and EGCG (epigallocatechin gallate). There are at least 5 proven ways they can help you lose weight:
Block conversion of energy into fat.
Help your body absorb less dietary fat.

Green Tea Weight Loss Fact #4:
Some green tea fat burner products claim that they can help to suppress your appetite. This is highly misleading.
A 2000 study conducted by University of Chicago found that rats consumed less food only when they were injected with green tea extract, but not when they drank green tea.
Therefore, for green tea to act as an appetite suppressant, you would have to either drink green tea constantly or consume tea extract at much higher levels than what is found in the market today.
Beware of companies making misleading claims on green tea's appetite suppressing effect. Some weight loss products can make you feel less hungry because they contain chromium, not because of the green tea extract.
Green Tea Weight Loss Fact #5:
Doing exercise can help you lose weight in three different ways:
Burns calories. Your burn extra calories when you engage in physical activities.
Boosts metabolism. Your energy level stays high for a period of time after you finish exercising.
Increases muscle mass. When you exercise, you develop lean muscle mass. Your metabolism rate is determined largely by how much muscle you carry. So having more muscle makes it easier for you to keep slim.
Getting into an exercise routine is hard work. The good news is that drinking green tea can increase your endurance level by up to 24%.
Researchers found that mice that exercised regularly lost 24% of additional weight gain introduced by a high fat diet. Mice that drank green tea lost 47%. Mice that exercised AND drank green tea lost 89%!
It was found that mice that exercised and drank green tea burned the most energy and fat even when they were resting. Mice that drank green tea also burned more fat during exercise.
Surprisingly, the study found that drinking green tea alone helps lose more fat and weight than exercising alone would for mice.
Green Tea Weight Loss Fact #6:
Water, Muscle or Fat Loss?
The American College of Sports Medicine (ACSM), the largest and most respected health, medical and exercise organization in the world, has established guidelines for healthy weight loss. They recommend a weight loss goal of one to two pounds per week.
According to Tom Venuto, author of the excellent book Burn the Fat, it is possible to lose more than two pounds per week, but if you do, most of the additional weight will usually be water and muscle.
When you lose water weight, you will gain it back immediately as soon as you rehydrate yourself. When you lose muscle, your metabolic rate slows down, making you more likely to regain the lost weight later.
Green tea weight loss is no exception! Permanent weight loss is slow because it involves fat loss, not water or muscle loss. And green tea is proficient in promoting fat burning.
Green Tea Weight Loss Fact #7:
Lose Weight Fast? How Soon Can You See Results?
Don't let anyone fool you into thinking that green tea acts fast!
Studies by Dulloo and Rumpler used a state-of-the-art metabolic chamber to measure the energy expenditure of their study subjects over 24 hours. They found that green tea increases metabolism by 2.9% and 4% and fat burning by 12% and 35% respectively.
If you burn 2,000 calories a day, this translates to a savings of up to 80 calories, or 8 pounds a year, not bad for just a few cups of soothing tea! After a few years, each little cup adds up to a gigantic slimming effect.
How quickly you lose weight depends on your diet and lifestyle. No one can guarantee how many pounds you can shed in a week!
Green Tea Weight Loss Fact #8:
Dosage Versus Duration
More green tea will help you lose more weight, but only up to a certain amount. So far scientists have not found evidence that consuming a lot more green tea will help you lose a lot more weight (i.e. dose-dependent relationship is not well established).
However, there is emerging evidence that the amount of time during which you drink green tea is important. The longer you drink it, the more fat it burns.
A Taiwanese population study found that 140 people who were regular tea drinkers for more than 10 years had 20% body fat. This is significantly lower than the non tea drinkers with 25% body fat.
In other words, develop the good habit of drinking high quality green tea, and you will stand a much better chance of staying healthy and slim in the years to come.
Green Tea Weight Loss Fact #9:
Ideal For Weight Control
After you have successfully regained your curvy shape, what comes next?
The beauty of green tea is that, unlike other herbs and supplements, you can drink 3 to 6 cups daily for the rest of your life without having any side effects. Together with its other powerful health benefits, this means green tea is an ideal weight maintenance beverage.
A study conducted by Mastic University in United States found that green tea extract consisting mainly of epigallocatechin gallate (EGCG) and caffeine can limit initial weight loss to 5% to 10%.
Green Tea Weight Loss Fact #10:
High Caffeine Consumers Beware!
If you are a heavy coffee drinker and are hooked on caffeine, you may want consider switching over to green tea for two reasons:
Green tea contains less caffeine. A widely accepted rule of thumb is that it contains half the amount of caffeine found in coffee.
Green tea also contains a natural relaxant called theanine, which is known to promote a feeling of well-being. If you are at work, it will improve your concentration and productivity.
But there is a catch. Although you will reap the many health benefits of green tea, you will lose less weight than a low caffeine consumer.
In the same study quoted above, participants maintained their weight by drinking a caffeinated green tea (consisting of 270 milligrams of EGCG and 150 milligrams of caffeine).
High caffeine consumers did not benefit from the green tea. But low caffeine consumers continued to lose weight in the weight maintenance phase through higher metabolism and fat burning.
So by all means drink more green tea for its health and fat burning effect, but have a more realistic expectation of what it will do for you in term of weight loss!

Green Tea Benefits: Weight Loss with Caffeine and Theanine
Proven Benefits of Tea
Green tea is the most healthy drink in the world.
It’s loaded with nutrients and antioxidants which have powerful effects on the body.
This includes a reduced danger of cancer, improved brain function, fat loss and a number of other incredible benefits.
Here are the health benefits of green tea which were supported in human research studies.
Green Tea Features Various Effective Compounds That Can Enhance Health
Green tea is more than just green liquid.
It is made mostly of the bioactive compounds in the tea leaves, which includes large amounts of important nutrients.
It is loaded with polyphenols like flavonoids and catechins, which function as strong antioxidants.
These materials can reduce the formation of free radicals in the body, protecting molecules and cells . These free radicals are recognized to play a role in aging and a variety of diseases.
One of the more powerful compounds in green tea is the antioxidant Epigallocatechin Gallate (EGCG), that has been analyzed to take care of various disorders and could be among the primary reasons green tea has such strong medicinal properties.
Green tea also offers small amounts of minerals that are essential for health.
Make an effort to choose a higher quality brand of green tea, because a number of the low quality brands can contain excessive rates of fluoride.
That being said, even if you select a lesser quality brand, the gains still far outweigh any risk.
Bottom Line: Green tea is loaded with effective compounds that can have various beneficial effects on well-being.
Brain Function Cans Improve and Make You Smarter
Green tea does more than just keep you awake, additionally, it may make you smarter.
The key active ingredient is caffeine, which is a known stimulant.
It doesn’t contain as much as coffee, but enough to produce a reaction without causing the “jittery” effects associated with too much caffeine.
What caffeine does in the mind is to block an inhibitory neurotransmitter named Adenosine. This manner, it actually increases the firing of neurons as well as the concentration of neurotransmitters like dopamine and norepinephrine.
Caffeine has been intensively studied before and consistently contributes to advancements in a variety of facets of brain function, including improved mood, vigilance, reaction time and memory.
Nonetheless… green tea contains more than just caffeine. It also has got the amino acid L-theanine, which has the capacity to cross the blood-brain barrier.
L-theanine increases the activity of the inhibitory neurotransmitter GABA, which has anti-stress effects. Additionally, it increases dopamine and also the production of alpha waves in the brain.
Studies show that caffeine and L-theanine may have synergistic effects. The mixture of the two is very strong at improving brain function.
Due to the L-theanine and the smaller dose of caffeine, green tea can provide you with a far milder and distinct kind of “buzz” than coffee.
Many individuals report having energy that is more secure and being considerably more productive when they drink green tea, compared to coffee.
Bottom Line: Green tea contains less caffeine than coffee, but enough to produce an effect. In addition, it comprises the amino acid L-theanine, which could work with caffeine to improve brain function.
Green Tea Increases Fat Burning and Improves Physical Performance
Odds are that green tea will likely be on there when you look at the ingredients list for almost any fat burning supplement.
This is because green tea has been shown to increase fat burning and boost the metabolic rate, in human controlled trials.
In one study in 10 healthy men, green tea increased energy expenditure by 4%.
Another study revealed that fat oxidation was increased by 17%, suggesting that green tea may selectively raise the burning of fat.
Nonetheless, I Had like to point out that some studies on green tea don’t demonstrate any increase in metabolism, so the effects may depend on the person.
Caffeine itself has also been proven to improve physical performance by mobilizing fatty acids from the fat tissues and making them accessible to be used as energy.
In two independent review studies, caffeine has been shown to increase physical performance by 11-12%, on average.
Bottom Line: Green tea has been proven to boost the metabolic rate and increase fat burning although not all studies agree.
Antioxidants in Green Tea May Reduce Your Risk of Various Kinds of Cancer
Uncontrolled development of cells causes cancer. It’s one of the top causes of death in the world.
It is well known that oxidative damage contributes to the development of cancer and that antioxidants might have a protective effect.
Therefore it makes perfect sense that it could lower your danger of cancer, which it appears to do green tea is a superb source of powerful antioxidants:
Breast cancer: A meta-analysis of observational studies found that women who drank the most green tea had a 22% lower risk of developing breast cancer, the most typical cancer in women.
Prostate cancer: One study found that men drinking green tea had a 48% lower risk of developing prostate cancer, which can be the most frequent cancer in men.
Colorectal cancer: A study of 69,710 Chinese girls found that green tea drinkers had a 57% lower risk of colorectal cancer.
Multiple other observational studies reveal that green tea drinkers are significantly less likely to get various types of cancer.
It is vital to remember that it could be a bad idea to put milk in your tea, because it can decrease the antioxidant value.
Bottom Line: Green tea has powerful antioxidants that will protect against cancer. Multiple studies reveal that green tea drinkers have a lower risk of various kinds of cancer.
Green Tea May Protect Your Brain in Old Age, Lowering Your Own Risk of Alzheimer’s and Parkinson’s
Not only can brain function improve in the short term, it may also protect your brain in old age.
Alzheimer’s disease is a leading source of dementia as well as the most typical neurodegenerative disease in individuals.
Parkinson’s disease involves the departure of dopamine producing neurons in the mind and is the next most common neurodegenerative disorder.
Multiple studies reveal that the catechin compounds in green tea may have various protective effects on neurons in test tubes and animal models, potentally lowering the risk of Alzheimer’s and Parkinson’s.
Bottom Line: The bioactive compounds in green tea might have various protective effects on neurons and could reduce the risk of both Alzheimer’s and Parkinson’s, the two of the most common neurodegenerative illnesses.
Green Tea Can Kill Bacteria, Which Improves Dental Health and Lowers Your Risk of Infection
The catechins in green tea have other biological effects also.
Some studies show they can kill bacteria and inhibit viruses like the influenza virus, potentially lowering your own risk of infections.
Streptococcus mutans is the primary dangerous bacteria in the mouth. It is a top contributor to cavities and tooth decay and causes plaque formation.
Studies reveal the catechins in green tea can inhibit the development of streptococcus mutans. Green tea consumption is associated with improved dental health along with a lower danger of caries.
Another wonderful advantage of green tea… multiple studies reveal that it can reduce bad breath.
Bottom Line: The catechins in green tea may inhibit the development of some viruses and bacteria. This can lower the risk of infections and lead to a lower danger of caries advancements in dental health and reduced bad breath.
Green Tea May Lower Your Risk of Type II Diabetes
Type II diabetes is a disease which has reached epidemic proportions in recent decades and now afflicts about 300 million people worldwide.
This disease causes raised blood sugar levels caused by insulin resistance.
Studies reveal that green tea can improve insulin sensitivity and reduce blood glucose levels.
One study in Japanese individuals found that people who drank the most green tea had a 42% lower risk of creating type II diabetes.
Based on a review of 7 studies with a total of 286,701 people, green tea drinkers had an 18% lower risk of becoming diabetic.
Bottom Line: Some managed trials demonstrate that green tea can cause moderate reductions in blood sugar levels. It might likewise lower the possibility of developing type II diabetes in the long term.
Green Tea May Reduce Your Risk of Cardiovascular Disease
Cardiovascular diseases, including heart attacks and stroke, are the largest causes of death in the world.
Studies reveal that green tea can improve a number of the risk factors for these ailments.
This consists of total cholesterol, LDL cholesterol and triglycerides.
Green tea also drastically raises the antioxidant capability of the blood, which shields the LDL cholesterol particles from oxidation, which is one section of the pathway towards heart disease.
Given the advantageous effects on risk factors, it is not surprising to note that green tea drinkers have up to a 31% lower risk of cardiovascular disease.
Bottom Line: Guard the LDL particles from oxidation, also as green tea was shown to lower total and LDL cholesterol.
Yonei Y, Takahashi Y, Hibino S, Watanabe M, Yoshioka T.
Supposedly, it suppresses appetite, boosts serotonin levels, and promotes weight-loss.
Observational studies show that green tea drinkers have a lower risk of cardiovascular disease.
Green Tea Can Help You Lose Weight and Lowers Risk of Becoming Obese
Given that green tea can raise the metabolic rate in the short term and increases insulin sensitivity, it makes sense that it might allow you to lose weight.
Several studies show that green tea leads to declines in body fat, particularly in the stomach area.
A studiy with a randomized controlled trial in women as well as 240 men that went on for 12 weeks. In this study, the green tea group had significant decreases in body fat percentage, body weight, waist circumference and abdominal fat.
Nevertheless, some studies do not show a statistically significant increases in weight loss with green tea, so this needs to be taken with a grain of salt.
Bottom Line: Some studies show that green tea leads to increased weight loss. It is particularly effective at reducing the dangerous abdominal fat.
Green Tea May Reduce Your Risk of Dying and Help You Live Better
Of course, we all have to die eventually. That is inescapable.
However, given that green tea drinkers are simply at a lower risk of cancer and cardiovascular disease, it makes sense that it may allow you to live longer.
In a study of 40,530 Japanese adults, those who drank the most green tea (5 or more cups per day) were significantly less likely to die during an 11 year period:
Death of all causes: 23% lower in women, 12% lower in men.
Death from heart disease: 31% lower in women, 22% lower in men.
Death from stroke: 42% lower in women in men.
Another study in 14,001 elderly Japanese people aged 65-84 years found that those who drank the most green tea were 76% less likely to die during the 6 year study period.

Slim down in order to feel better and lower your own risk of chronic diseases, then you definitely may want to consider making green tea a regular portion of your own life.
Does Green Tea have Caffeine?
Yes, green tea has caffeine. But in lower amounts then coffee. However since you can often drink more green tea you will get the same amount of caffeine.
The benefits of using green tea in weight loss are numerous as it is a natural food product. It is also used in many diet supplements and weight loss pills as a component because of the nutrients and benefits it has. It also actively assists the body to lose weight. Before you embark on the green tea weight loss diet, you must fully understand the way it works because just like any other weight loss program, you need to work hard, exercise and eat right to lose weight.
Green tea increases the body’s metabolism rate. This process is known as thermogenesis. The way drinking of green tea does this is, because it contains high amounts of catechin polyphenols (like caffeine) which are compounds that increase thermogenesis. The way this happens is that this compounds causes fat stored in the body to be released into the blood stream so that it is used as fuel. They also aid the body to shed this fat by burning it and getting rid of extra water in the body and excess energy which is produced by burning fat.
Polyphenols is a compound that activates the enzymes that dissolves triglycerides and polyphenols are found in green tea. Triglycerides are stored fats in the body and when they are in excess amounts then there is obesity. Discernible weight loss is seen after a long period of time, since the amounts of fat burned are not enough for weight loss that is obvious.
To lose weight you need to combine exercise with a dietary change such as eating more vegetables and fruits. Drinking green tea will help boost your body metabolism, burn calories and increase the energy your body produces and it helps build muscle. Muscles lead to increased metabolism so that even when you are sedentary, muscles burn more fat as compared to fat. The way green tea aids fat loss while exercising is that it makes your body release stored fat which are burned while exercising as opposed to using carbohydrates that are in your digestive system. This makes you lose weight faster.
Green tea also blocks fat absorption so that you tend to burn the fat rather than your body storing it which leads to weight gain. It is also a healthy alternative to drinking fizzy and carbonated drinks such as sodas which have high levels of sugar which are a big contributing factor to adding weight. When you drink green tea as an alternative to coffee and soft drinks then it will hydrate you, and provide benefits such as nutritional value and antioxidants which prevents diseases such as cancers, heart diseases and other ailments.
Another way that green tea helps in weight loss is that it helps you by lowering your appetite. This happens since green tea controls the way glucose is released into your system. If you don’t have enough glucose in your system, this sends signals to your brain so that you feel hungry and replenish the glucose supplies by eating. If you are used to eating junk food or binge eating, drinking green tea can help you regulate that kind of eating and it is also good to drink it while dieting as it will help reduce food cravings. Green tea will also maintain LDL cholesterol levels in your body so that if you have lost weight, that weight loss is maintained.
Green tea weight loss will be effective only if combined with exercise and diet changes. The benefits of using green tea with exercise and diet produces results faster as compared to someone who doesn’t drink green tea. A person who drinks green tea will still have less body fat as compared to one who doesn’t if both don’t exercise.
Another health benefit of using green tea weight loss diet is that green tea contains caffeine. You will also be more relaxed and will concentrate better because green tea contains theanine which is a natural relaxant. Green tea is also a natural product meaning your body will respond well to it without experiencing the side effects associated with medications and weight loss surgery.
Green Tea and the Metabolism
Metabolism is a complex idea with diverse meaning to different people. There is an assortment of myths that go around regarding this small, yet convoluted word, whereas essentially it refers to the amount of calories your body burns each day .
For those of you who are wondering what the effect of the metabolism is. You eat every day, and your meals have calories, sometimes exactly as much as needed.
Sometimes so much that you end up worrying that you might not be able to wear that beautiful dress for your sister’s wedding next month!
However, metabolism is something that helps you out in this case. It burns the calories of your body , and thus helps you to lose a few extra pounds.
As stated, many people have this false belief that you’re with a certain metabolism rate, and that the rate cannot be accelerated, which is completely wrong. There are certain factors and actions that can help to raise one’s metabolism rate , thus ensuring a healthier life for that person.
They include high protein intake, engaging into extensive work outs, moving away from stress, drinking enough water etc. However, recently is has been discovered that green tea has some properties that accelerates the metabolism as well, and hence, helps in losing body weight stored in the form of fat.
During the last ten years, more than 300 medical studies have described various health benefits of tea (Camellia sinensis) and there is growing evidence that tea is even more healthful than previously believed, and that both processed (oolong and black) and unprocessed (white and green) tea are beneficial. Two studies, one in the U.S. and one in Europe, released in spring 2007 revealed that Green Tea has even more stellar benefits, particularly for leukemia, cancer, and most recently, in combination with other elements to fight prostate cancer.
All true tea contains seven of the eight essential human amino acids, the “good guys” that repair tissues, build cells, and attack bacteria and viruses. Tea also has an amino acid exclusive to it called theanine which helps in the biosynthesis of such antioxidants as catechins and polyphenols.
Of all these “good guys” the polyphenol called ECGC is the most powerful and its presence is often five times greater in Green Tea than in oolong or black primarily because it is not oxidized, leaving its enzymes relatively unaffected by heat and other processing techniques.
Researchers study how ECGC, which is epigallocatechin 3-gallate, can be harnessed to fight a variety of diseases including CLL, a virulent form of leukemia, and a variety of cancers in which ECGC works to reduce the size and number of tumors, slow the growth of known cancer cells.
One study revealed how a combination of green tea and a COX-2 inhibitor can work better in the fight against cancer than independently. Researchers from the University of Wisconsin-Madison demonstrated that low doses of the COX-2 inhibitor celecoxib, administered with ECGC, slows the growth of human prostate cancer.
Garcinia Cambogia received its first notable mention in the prestigious Journal Of TheAmerican Medical Association, where the first of its kind well-controlled trial on theingredient was published.
Their experiments, performed in cell cultures and in a mouse model for the disease, showed that, “celecoxib and Green Tea have a synergistic effect — each triggering cellular pathways that, combined, are more powerful than either agent alone,” said Hasan Mukhtar, Ph.D., professor of dermatology at the University of Wisconsin and member of Wisconsin’s Paul Carbone Comprehensive Cancer Center. This development may lead to a preventative treatment for prostate cancer. In 2004, Mukhtar and his colleagues demonstrated that Green Tea polyphenol EGCG has cancer-fighting abilities of its own and can inhibit experimental tumor growth in animals.
Scientists in Madrid and Great Britain reported that they now know why Green Tea’s EGCG works in fighting cancer. British researcher Roger Thorneley said that studies have shown for the first time that ECGC, which is present in Green Tea five times as much as other teas, inhibits the enzyme dihydrofolate reductase (DHFR), which is a recognized, established target for anti-cancer drugs. He added that identifying this enzyme in tumor cells has led to their understanding of how EGCG binds with a specific enzyme which then limits the growth of cancer cells. Its chemical structure is very similar to the chemotherapy drug methotrexate. This new understanding paves the way for more effective cancer fighting drug based on the structure of the ECGC molecule. Researchers are from University of Murcia in Spain and at the John Innes in Norwich, England.
Green tea benefits for weight loss
Weight loss has become one of the most profitable industries, without a shadow of a doubt. There are an endless number of conflicting types of diet plans, each claiming to offer the secret to permanent weight loss. There are an equal number of so called diet helpers, innocent ingredients that supposedly help the body to shed excess weight.
It has been said that green tea benefits weight loss and that drinking green tea can help a person to lose weight, whether on a diet or not.
Is there any truth to this claim? Is it true that green tea benefits weight loss? We will present detailed information about the relationship between green tea and weight loss.
Before delving into whether or not green tea benefits weight loss, it is wise to understand a little bit about the history of green tea.
Green tea is not a new kid on the block by any means. It has been around for literally thousands of years, originating in the Orient. Green tea is a rather broad term that encompasses literally hundreds of different varieties.
Green tea has many proven benefits and not just for weight loss.
For starters, green tea is high in lipids, which undoubtedly accounts for the proven reduction of over all cholesterol levels. It also contains high levels of antioxidants and amino acids, as well phytochemicals and other minerals.
As for the weight loss benefits of green tea, recent studies have proven that green tea helps the body to dissolve triglycerides in the human system, thanks to the natural polyphenols contained in green tea.
Another key to weight loss is increasing the body’s metabolism. Thanks to many antioxidants, including EGCG and caffeine, green tea has a proven track record of helping the body to speed up the metabolism and thus get rid of unwanted weight. The combination of EGCG and caffeine works on the nervous system and stimulates the body to let go of fat cells that are being stored in the body. With these fat cells released, the body can then use them as fuel, reducing the amount of calories required on a daily basis, plus, getting rid of unnecessary fat stored in the body.
Of course, drinking green tea isn’t a cure all for weight loss. Studies have shown that green tea aids in losing weight and that it is most effective when combined by diet plan as well as an exercise plan.
Should green tea be included into an over all diet strategy?
Every person is unique, and therefor every weight loss plan is also unique. There is ample evidence that shows that green tea supports a healthy and normal weight loss with minimal, if any side effects. Of course, deciding to add green tea to a diet plan is a matter of personal choice, however with all of the health perks, there really isn’t any down side to adding green tea as part of a healthy life style.

Best green tea diet supplement
There are a number of green tea diet supplements on the market, and since no studies have been done comparing all of them, it is impossible to say honestly which one of these products is the best green tea diet supplement.
Green tea has several potential health benefits that are slowly being discovered: Antioxidant, Alzheimer’s disease, cancer prevention, anti aging, heart health, blood thinning are some benefits or areas where research has been done.
Human research is still early, but the potential health benefits ascribed to green tea include antioxidant effects, cancer prevention, antiviral effects, blood thinning properties, improving cardiovascular health, slowing mental decline, enhancing weight loss and fat burner, arthritis protection, and protecting the skin from the damage caused by ionizing radiation.
As you would expect there is a wide variation of satisfaction with a product like this.
Long term human research is required before we determine the appropriate dosage and amount of green tea or extract required to provide these health benefits. But, in the meantime, there is no reason to ingest too much of it.
Green tea and weight loss diet – a fat burner?
Green tea consumption is reportedly associated with various health-promoting properties. For example, it has been shown to promote fat oxidation in humans at rest and to prevent obesity and improve insulin sensitivity in mice.
Human studies regarding the benefit of green tea in weight loss have not shown consistent results. In one study mentioned below, daily consumption of green tea for 12 weeks reduced body fat but another study did not show weight loss with the use of green tea extract supplements. Scientists are still evaluating whether a green tea pill by itself leads to weight loss. See below for more green tea and weight loss research information. If you plan to drink green tea for weight loss or take it as a diet pill, avoid drinking after mid afternoon or early evening so that your sleep is not disturbed. It is quite possible that the combination of green tea extract and other supplements that influence appetite or metabolism could lead to weight loss.
Effect of green tea extract on obese women: a randomized, double-blind, placebo-controlled clinical trial.
Clin Nutr. 2008. Community Medicine Research Center, National Yang-Ming University, Taipei, Taiwan.
Seventy-eight of 100 obese women aged between 16 and 60 years with BMI>27 kg/m were randomly divided into Groups A and B. Group A received green tea extract while Group B took cellulose as a placebo, one capsule (400mg) three times each day for 12 weeks. The body weight (BW), body mass index (BMI) and waist circumflex (WC) were measured at the beginning of the study and after 12 weeks of treatment with green tea extract. There was only a 0.3% reduction in BW after 12 weeks of treatment with green tea extract. There was no statistical difference in % reduction in BW, BMI and WC between the green tea extract and placebo groups. Within group comparison revealed that the green tea extract group had significant reduction in LDL-cholesterol and triglyceride, and marked increase in the level of HDL-cholesterol, adiponectin and ghrelin. On the other hand, the placebo group showed significant reduction in triglyceride only, and a marked increase in the level of ghrelin alone. This study showed no statistical difference in % reduction in BW, BMI and WC between the green tea extract and placebo groups after 12 weeks of treatment. The intake of green tea extract (491 mg catechins containing 302 mg EGCG) for 12 weeks is considered safe.
Ingestion of a tea rich in catechins leads to a reduction in body fat and LDL in men.
American Journal of Clinical Nutrition, 2005
Catechins, the major component of green tea extract, have various physiologic effects. We investigated the effect of catechins from green tea on body fat reduction. Gealthy Japanese men were divided into 2 groups with similar BMI and waist circumference distributions. A 12-wk double-blind study was performed in which the subjects ingested 1 bottle oolong tea /d containing 690 mg catechins or 1 bottle oolong tea /d containing 22 mg catechins. Body weight, BMI, waist circumference, body fat mass, and subcutaneous fat area were significantly lower in the green tea extract group than in the control group. Daily consumption of green tea containing 690 mg catechins for 12 wk reduced body fat, which suggests that the ingestion of catechins from green tea might be useful in the prevention and improvement of lifestyle-related diseases, mainly obesity.
Anti-obesity effects of green tea: from bedside to bench.
Mol Nutr Food Res. 2006.
Green tea, green tea catechins, epicatechin, and epigallocatechin gallate (EGCG) have been demonstrated in cell culture and animal models of obesity to reduce adipocyte differentiation and proliferation, lipogenesis, fat mass, body weight, fat absorption, plasma levels of triglycerides, free fatty acids, cholesterol, glucose, insulin and leptin, as well as to increase beta-oxidation and thermogenesis. Adipose tissue, liver, intestine, and skeletal muscle are target organs of green tea, mediating its anti-obesity effects. Studies conducted with human subjects report reduced body weight and body fat, as well as increased fat oxidation and thermogenesis and thereby confirm findings in cell culture systems and animal models of obesity. There is still a need for well-designed and controlled clinical studies to validate the existing and encouraging human studies.
A 50 percent pure extraction of EGCG – a flavonoid which is the most potent of four major catechins in green tea, was examined by Dr. Stephane Bastianetto at the Douglas Mental Health University Institute, McGill University in Montreal. In the study, rats were fed food that contained Teawell 50, compared to a control group whose food did not contain the extract. Results showed that rats who ate Teawell 50 had an reduction of free radicals in a key region of the brain involved with learning and memory. This region is severely damaged when Alzheimer’s is present. “This suggests regular consumption of green tea may protect against the deleterious effects of oxidative stress, delaying or preventing age-related memory deficits,” said Dr. Bastianetto.
Anti aging benefit of drinking green tea
According to a study done with Japanese adults, those who consumed the most green tea were less likely to die from cardiovascular disease or any other cause, except cancer, than were the less-frequent green tea drinkers. Dr. Kuriyama and colleagues analyzed information on 40,530 Japanese adults, 40 to 79 years old, who participated in the Ohsaki National Health Insurance Cohort Study. The subjects, who were followed an 11 year period, were from a northeastern region of the country where most of the adults drink green tea three or more times per day. Adults who drank the most were the least likely to die from cardiovascular disease. Men who consumed at least five cups each day were less likely to die from any cause. Whereas, women who drank five or more cups of green tea each day were 23 percent less likely to die from any cause and 31 percent less likely to die from cardiovascular disease.
Comments: For the time being, if you don’t drink green tea, it may be a good idea to have a cup a day or a few times a week. If you already drink it on a daily basis, you could perhaps add another cup a day. It’s also possible that drinking a variety of teas may provide more benefit than just drinking additional green tea. Who’s to say other herbal teas (and there are so many to choose from) are not as healthy? Another option is to take a green tea extract supplement a few times a week. Avoid the use of the tea or the supplement after mid afternoon since the caffeine and stimulants may interfere with sleep. One factor to consider is that this study was done in Japan. Americans have a different diet and lifestyle. Will the results be similar in those on a Western diet?
Green tea extract capsules, when given to humans, increase the production of such as glutathione S-transferase (GST) enzymes which are helpful in detoxification and cancer prevention. Dr. H.-H. Sherry Chow, of the University of Arizona, Tucson, gave volunteers four green tea extract capsules, each containing 200 mg of epigallocatechin gallate, every morning prior to eating. This provided the equivalent amount of epigallocatechin gallate obtained from drinking 8 to 16 cups of green tea daily. Those with the lowest GST levels at the start of the study and who took the green tea extracts were found to have glutathione S-transferase enzymes increased. Those who had good levels of glutathione S-transferase did not have much of a change in their levels. Cancer Epidemiology, Biomarkers and Prevention, 2007.
Anti-platelet (blood thinning) benefit of green tea catechins is mediated by inhibition of cytoplasmic calcium increase.
Green tea extract for arthritis and healthy joints
Some green tea catechins are chondroprotective (protecting cartilage) in lab studies, and that consumption of green tea may benefit the arthritis patient by reducing inflammation and slowing cartilage breakdown. Further studies will be required to determine whether these compounds access the joint space in sufficient concentration and in a form capable of providing efficacy when ingested as tea or capsule.
Several compounds in green tea have anti cancer potential, including against prostate cancer.
Pancreatic cancer – In mouse studies, green tea extract EGCG inhibits pancreatic cancer growth, invasion, metastasis and angiogenesis. Human studies will elucidate whether green tea extract could be used for the management of pancreatic cancer prevention and treatment.
Drinking green tea or taking a supplements does not seem to have a major role to play in lowering blood sugar, but the antioxidant effects are nevertheless beneficial for those with diabetes. Green tea may reduce advanced glycation end products and reduce the rate of collagen cross linking. It does not appear that it has much of an influence on blood sugar levels. However, this does not mean it is not beneficial to those with diabetes.

Since it has has potent polyphenol antioxidants, drinking it or taking an extract may be helpful in terms of overall antioxidant status in the body. However, green tea extract may reduce collagen cross linking which is often a consequence of high blood sugar levels.
Green tea has preventive effects on both chronic inflammatory diseases and lifestyle-related diseases including cardiovascular disease.
Drinking green tea can protect heart arteries by keeping them flexible and relaxed, and therefore better able to withstand constant changes in blood pressure. Dr. Nikolaos Alexopoulos of Athens Medical School in Greece, reports that among 14 subjects, those who drank green tea showed greater dilation of their heart arteries on ultrasound 30 min. later than those drinking either diluted caffeine or hot water. Green tea flavonoids works on the lining of blood vessels, helping cells there to secrete the substances needed to relax the vessels and allow blood to flow more freely. These flavonoids act as antioxidants and help prevent inflammation in body tissue, that keep the vessels pliable. Flavonoids also protect against the formation of clots, which are the primary cause of heart attacks.
Exercise and athletic performance
The effects of EGCG on fat oxidation and endurance performance in male cyclists.
Int J Sport Nutr Exerc Metab. 2009. School of Sport and Exercise Science, Waikato Institute of Technology, Hamilton, New Zealand.
Eight male cyclists completed a study incorporating a 3-way crossover, randomized, placebo-controlled, diet-controlled research design. All participants received 3 different treatments (placebo 270 mg, EGCG 270 mg, and placebo 270 mg + caffeine 3 mg/kg) over a 6-day period and 1 hr before exercise testing. It was concluded that green-tea extract offers no additional benefit to cyclists over and above those achieved by using caffeine.
Flavanol epigallocatechin-3-gallate is shown to be a potent natural inhibitor of leukocyte elastase that may be used to reduce elastase-mediated progression to emphysema.
Black Tea — During black tea production, oxidation is promoted so that most of these substances are oxidized.
Green tea is prepared in such a way as to prevent the oxidation of green leaf polyphenols.
Oolong tea is a partially oxidized product. Of the approximately 3 million metric tons of dried tea manufactured, only 20% is green tea and less than 2% is oolong tea.
There are hundreds of types of green tea and countless green tea growing farms. Each batch will have a slightly different caffeine amount. In addition to caffeine, green tea has beneficial compounds mostly of the polyphenol class. A study done in Portugal evaluating various types of green tea found the caffeine content in green tea ranged between 140 to 340 mg per liter.
Green Tea side effects, safety, danger
A common green tea side effect is shallow sleep. Green tea has caffeine and methylxanthines, so avoid drinking or taking the capsules in the evening. We have not come across any other common green tea side effects at this time except this one caution:
Caution: In rare cases extracts from green tea have been reported to adversely affect the liver. Discontinue use and consult a healthcare practitioner if you have a liver disorder or develop symptoms of liver trouble, such as abdominal pain, dark urine, or jaundice. If you plan to take green tea extract for prolonged periods, take a week off each month.
I have a question about the recent decision to put warning labels on supplements containing green tea extracts. it warns of possible liver damage. Are there supplements derived from green tea extracts which will not be easily identifiable by their labels?
A. The study that found green tea extract polyphenols may damage liver tissue used high doses injected into small mammals. Many Japanese drink green tea several cups a day without problems. We are not concerned that taking a green tea supplement at one capsule or tablet a few times a week would cause any liver problems.
Hepatotoxicity from green tea: a review of the literature and two unpublished cases.
Eur J Clin Pharmacol. 2009. Department of Physiology and Pharmacology, Sapienza, University of Rome, Rome, Italy.
To review the current literature on suspected green tea-related liver damage reactions and to describe two new cases reported within the framework of the Italian surveillance system of natural health products. A literature search of publication between 1999 and 2008 retrieved 34 cases of hepatitis. Histological examination of the liver revealed inflammatory reactions, cholestasis, occasional steatosis, and necrosis. There was one reported death. A positive rechallenge occurred in seven cases (20%). In the two new cases. Our analysis of the published case reports suggests a causal association between green tea and liver damage. The liver toxicity is probably due to epigallocatechin gallate or its metabolites which, under particular conditions related to the patient’s metabolism, can induce oxidative stress in the liver. In a few cases, toxicity related to concomitant medications could also be involved.
Safety of green tea extracts : a systematic review by the US Pharmacopeia.
Drug Saf. 2008. US Pharmacopeia, Rockville, Maryland, USA.
Recently, regulatory agencies in France and Spain suspended market authorization of a weight-loss product containing green tea extract because of liver harm concerns. This was followed by publication of adverse event case reports involving green tea products. In response, the US Pharmacopeia (USP) Dietary Supplement Information Expert Committee (DSI EC) systematically reviewed the safety information for green tea products in order to re-evaluate the current safety class to which these products are assigned. A total of 216 case reports on green tea products were analysed, including 34 reports concerning liver damage. Twenty-seven reports pertaining to liver damage were categorized as possible causality and seven as probable causality. Clinical pharmacokinetic and animal toxicological information indicated that consumption of green tea concentrated extracts on an empty stomach is more likely to lead to adverse effects than consumption in the fed state. Based on this safety review, the DSI EC determined that when dietary supplement products containing green tea extracts are used and formulated appropriately the Committee is unaware of significant safety issues that would prohibit monograph development, provided a caution statement is included in the labelling section.
Fresh green tea leaf is unusually rich in Polyphenols which may constitute up to 30% of the dry leaf weight. Polyphenols include catechins, flavanols, chlorogenic acid, epigallocatechin gallate (EGCG), and one unique to tea, theogallin. Caffeine in green tea is present at an average level of 3% along with very small amounts of methylxanthines, theobromine and theophylline. The amino acid theanine (5-N-ethylglutamine) is also unique to tea. The compound EGCG has been shown to regulate dozens of disease-specific molecular targets.
Q. I see supplements of EGCG being sold in high dosages. Are these safe to take?
A. Consumers are switching from regular tea to green tea and other herbal teas. We are not big fans of taking large doses of isolated substances from herbs, such as a high amount of EGCG, preferring to take the whole powder or a less concentrated extract. Many people think the higher the dose of a substance they supplement, the healthier they will be, but that may not always be the case, and often is not the case. So, for the time being, we don’t see the need to take a high dose of EGCG.
Q. Can you possibly tell me how many mg of caffeine would be in 50 mg of green tea (leaf) extract?
A. This is impossible to say accurately since there are countless extract potencies of green tea and countless varieties of green tea leaf and herb. The level of caffeine could vary significantly between different extracts, growers, processors, and manufacturers.
Q. I had been drinking 2 to 4 cups of green tea for about ten years, mostly organic and de-caf. Last year I found out about the fluoride issue and also found out that green tea contains fluoride. I had no major health problems, just annoying sinus problems which would turn into infections several times/year. I did however have a lowered white cell count during this time (3.8-4.2) Then I developed sleep problems about 3 years ago and tried just about everything for them. I gave up drinking green tea last year (still have a cup of coffee with caffeine). Not only have my sleep problems ceased, but my white cell count is back to normal. I still can’t believe the results but I still won’t go back to drinking green tea. I did the research and I must be sensitive to fluoride.
A. Green tea, even decaf, has many compounds in it, such as catechins, that cause alertness. Drinking two to four cups of green tea a day will likely cause shallow sleep and at this time we are not convinced that it is the fluoride causing it.
