Can Green Tea Diet Extract Make You Lose Weight?

There's nothing I love more than spending some time with Camellia Sinensis at the weekend.

If you’re thinking Camellia is the name of an exotic dancer that I hook up with on a Saturday night - you’d be mistaken.

Actually, Camellia Sinensis are the leaves that you brew in hot water to make a refreshing cup of Chinese green tea.

And it seems I’m not the only one.

In the US alone the consumption of green tea has increased by 60% in the last ten years.

But why has become so popular?

One big reason is that it help melt away unwanted fat. Not to mention its cancer fighting and anti-aging properties.

Which is all great, but it does have two major downsides

For one thing, you’ll have to drink a serious amount of tea to experience the benefits.

The second thing is the taste. Green tea can taste quite bitter and its not to everyone's liking.

But there’s good news.

With green tea extract you can still enjoy the fat burning and other health benefits of green tea without having to taste it.

What is Green Tea Extract?

Green tea extract or GTE for short, is a super-concentrated version of the stuff you drink from a cup.

According to the National Cancer Institute green tea extract is…

“A defined, decaffeinated green tea polyphenol mixture isolated from Camellia sinensis, a plant native to Asia, with antiviral and antioxidant activities and potential chemopreventive activity.

Green tea extract contains antioxidant compounds, including flavonoids, vitamins and polyphenols such as epigallocatechin-3-gallate (EGCG), which may have antineoplastic properties.”

The most common way to take GTE is take it as a supplement, but its also available in powder or liquid form.

The Health Benefits of Green Tea Extract

Weight Loss

Can Green Tea Extract Help You Lose Weight?

Green tea claims to have many health benefits, but can it help you look good in a bikini?

There’s plenty of research supporting these claims and you’ve probably read them yourself in a magazine or website.

For example, a study by Birmingham University in the UK found that taking green tea extract supplements 30 minutes before and after exercise increased fat oxidation rates 17% more that the placebo group. 

And it seems taking green tea extract as an effective weight loss solution isn’t just wishful thinking.

Further evidence proves the compounds contained in green tea not only raised metabolic rates but also produced higher rates of fat burning.

And that’s not all…

A randomized controlled trial revealed obese women lost two and half pounds after taking high doses of extract for 12 weeks. The results also revealed a decrease in their BMI, cholesterol levels and a shrinking waistline.

Green tea also contains caffeine which we know is a powerful stimulant and appetite suppressor.

But can it burn fat?

Not directly.

Let me explain.

Our body burns fat for one reason… to produce fuel for energy.

But burning fat doesn’t mean our fat cells are being held over a fire as if we’re toasting marshmallows. That would be painful.

When it comes to fat burning, fat in the form of free fatty acids need to released into the bloodstream.

An effective way of releasing free fatty acids is caffeine.

Through a process called lipolysis, caffeine stimulates the breakdown of fat cells which are then released for energy.

Caffeine makes this happen by boosting levels of a hormone called epinephrine, better known as adrenaline.

And its epinephrine that releases fatty acids into the bloodstream.

So it seems the anti-oxidants and caffeine working together are a potent catalyst for burning calories.


There is no shortage of green tea extract weight loss claims to be found on-line however, there are several studies that reveal the regular consumption of green tea extract can have a beneficial effect on our metabolism and our ability to burn excess fat.

Improving your Digestive Health

Growing evidence reveals a lack of gut bacteria and micro-organisms in our intestines is linked to a higher risk of obesity.

It turns out these micro-organisms living in our gut determine how effectively we digest food.

For example, gut bacteria can influence the way we absorb and store body fat.

Certain bacteria can help us digest and absorb antioxidants that prevent weight gain.

Certain bacteria can help us digest and absorb antioxidants that prevent weight gain.

And there are gut bacteria that stop us feeling hungry.

But what has this got to do with green tea?

Let me explain.

Supplementing green tea extract can help encourage the growth of healthy gut bacteria resulting in many health benefits, even weight loss.

According to one study two groups of mice were fed a high-fat diet, but only one groups diet was mixed with green tea extract.

The study measured a number of factors including gut inflammation, the composition of gut bacteria and levels of toxins in the blood caused by bad gut bacteria.

After the 8 week study, the group with their diet mixed with green tea extract improved in all the key targets with a 20% reduction in weight, lower levels of insulin resistance, inflammation and endotoxins in the blood.

Interestingly, to consume the same amount of green tea as the mice did you would have to consume 10 cups a day. That’s a lot of cups!

Boost Energy without the Jitters

We all know caffeine gives us a boost in the morning as well as preventing that mid-afternoon slump.

Even so, there’s a good reason to choose green tea over a cup of coffee.

Caffeine naturally occurs in green tea but the concentrations are lower compared to coffee.

In fact, you would have to drink 3 cups of green tea to match the same amount of caffeine contained in one cup of coffee.

I love my coffee but it gives me jitters if I drink more than one cup!But with green tea extract, you’re still getting a nice little boost of energy to inject into your workouts without getting the ‘shakes’.

Help Control Blood Sugar for Diabetes Management and Prevention

Controlling your blood sugar levels is probably the most important factor in maintaining your energy levels and weight.

Blood sugar levels that remain high is a strong indicator of diabetes - now the fastest growing disease in the United States.

Diabetes is an extreme form of blood sugar imbalance because the body can no longer produce enough insulin, the hormone that carries glucose into the cells. The result is too much insulin in the blood and not enough for the cells.

But there’s good news.

According to a number of studies drinking green tea may help people with diabetes.

It seems the catechins in green tea can help maintain blood sugar levels and therefore, keep your weight under control.

Also, a specific catechin called EGCG helps reduce amylase an enzyme that converts carbohydrates into sugar.

Even if you’re not diabetic taking green tea extract could lower your risk of getting the disease.

For example, in a Japanese study monitoring green tea consumption, discovered that people who drank 6 or more cups a day were 33% less likely to develop diabetes.

And don’t forget, when you take green tea extract supplement you’re getting the equivalent of 6 cups in one capsule.

Potent Cancer Fighter

Cancer occurs when cells in the body start behaving differently. Instead of working for the good of the body they start to cause havoc and destruction.

Now a healthy immune system will quickly deal with these rogue cells before they have a chance to run riot.

However, a weakened immune system, increases the risk of it being overcome by these rogue cells and the damage spreads.

An effective way to strengthen your immune system is to ensure your getting enough of anti-oxidants to protect you from cell damage.

It turns out, that EGCG, a particular catechin found in the Camellia Sinensis is a potent free radical destroyer and cell protector.

Potential Side Effects of GTE

People have been consuming green tea for thousands of years without any serious issues.

According to green tea is considered safe for most adults when taken in moderate amounts.

However, green tea extract side effects can occur when consumed at high doses and over long periods of time.

The side effects are often caffeine related resulting in symptoms such as;

  • sleep problems
  • headaches
  • dizziness
  • diarrhea
  • anxiety

In addition, the caffeine in green tea acts as a diuretic which can dehydrate you. You can avoid this by drinking water throughout the day.

Although rare, GTE can be toxic when taken at a very high dose. It seems that in high concentrations the catechins in green tea extract can stress out the liver. That’s why its important not to exceed the recommended dosage.

How much green tea extract is too much?

According to the European Food Safety Authority taking 800mg or more of extract may pose health concerns.

Also, it seems the absorption of catechins increase when your fasting. So, when dieting it may be safer to take the pills during a meal rather than an empty stomach.

So far, there isn’t any research that says green tea extract as a supplement for weight loss poses a serious threat to healthy adults.

The best way to minimize risks is to stay within the manufacturers recommended daily amount which is 150 to 500 mgs per day.

Types of Green Tea Extract

Even with its many health benefits most people don’t like green tea because of the bitter after taste.

And that’s a problem, because you have to drink lots of the stuff to experience the benefits.

Fortunately, the extract is available in a variety of forms, so you can enjoy the health benefits without the bitter after-taste .


You’ll find most green tea extract supplements are available in capsules or tablets.

Certain herbal blends, specifically designed for weight loss, may include other ingredients.

The ingredients may include the stimulant caffeine or appetite suppressants chromium or hoodia.

What if you enjoy drinking green tea but you don’t have the time or the inclination to brew it?

Liquid & Powder Extract

The good news, is that its also available as a powder mix or liquid.

Powder green tea is a convenient option - just add cold water and you’ve instantly got a refreshing, healthy iced tea.

The powder can be unsweetened or sweetened with added flavors to make the taste more palatable.

Another convenient option is liquid green tea extract. Most liquids come in bottles and its just a matter of sprinkling a few drops in water or a favorite beverage and you’re good to go. They’re also available in different flavors.

But, there’s something important to be aware of .

Both powder and liquid extracts involve more processing which means they tend to be lower in antioxidants compared to capsules.

So there you have it. You now know the three main types of green tea extract available and there pro’s and con’s.

Which to Choose?

As you’re goal is to lose weight the best option is to opt for capsules as they contain the highest concentrations of polyphenols.

But which green tea extract pills are the best for losing weight?

A difficult question to answer because there are so many brands to choose from.

But, there are three options that I think you should take a closer look at.

I’ve reviewed them briefly below:
