Wu Long Tea and Green Tea Scam Warning!
By Tom Venuto
You’ve probably seen the advertisements:
“Drink wu long tea and lose a jeans size every 7 days!”…
“Burn 20 lbs of fat in 30 days with wu long tea!” …
Maybe you even watched Oprah a few years ago when Dr. Perricone said that switching your coffee for green tea would help you take off the pounds.
You may have also read or watched countless news stories which say how healthy it is to drink
The odds are good that if you’re interested in improving your health and losing fat, you probably either drink tea, take a green tea supplement or you’ve at least thought about it.
But what if I told you that most of the fat reducing claims for green tea were absolute, total BS, based on misinterpretation or deliberate misreporting of the research?
Unfortunately, it’s true. If you’ve bought green tea
based on the claim that it causes large reductions
in body fat, then you have been scammed.
Here are the facts:
Green tea DOES stimulate your metabolism.
However, the research is very unclear about what kind
of impact this small, short term increase in metabolism
will have on your bodyweight in the long term
In the most often quoted study (Dulloo, 1999), A swiss
research team found that 270 mg of green tea extract
3X a day increased metabolic rate by the equivalent
of about 79 calories on average and increased the
oxidation of fat as the fuel source.
If you do the math, it appears that 79 kcal a day would
add up to an extra pound of fat lost every 44 days.
Not much, but you’ll take it, right? Hypothetically, that would add up to an extra 8 pounds lost per year.
What advertisements quoting this study don’t tell you
is that this and other similar studies did not even
measure long term change in body fat percentage or bodyweight.
They only measured a 24- hour increase in energy expenditure.
One study which is used as marketing ammunition to claim that wu-long tea burns 2.5 times more fat than green tea was based only on a 120-minute increase in energy expenditure! (reminds me of that Mark Twain quote: “There are lies, damned lies, and then there are statistics”)
Numerous follow up studies have confirmed the short term
increase in metabolism, but the studies are mixed on whether
green tea improves weight reduction or maintenance in the
The research IS compelling, but not conclusive.
As for ad claims that say you’ll lose a lot of weight just from drinking green tea… absolute BS! Hopefully the Federal Trade Commission will catch up with these scammers sooner rather than later, as the marketing messages on the Internet are getting louder and bolder every day.
As for health benefits - green tea is certainly a champ.
It’s high in antioxidants and there are more than 2,000
research citations about potential health benefits of
green tea (not to mention a 5,000 year history of use
in China and the far east).
Even if you’re a skeptic, green tea is hard not to like and
it’s hard to dispute that it’s a good idea to add green tea
to your nutrition program as one part of a well-balanced
But when it comes to claims for large and rapid losses in
bodyweight and bodyfat, (especially the wu-long tea ads
that are currently all over the internet), buyer beware.
The science we do have says that the thermogenic effect of
green tea - while very real - is also very small.
