Green Coffee Bean Extract Diet

Is the Green Coffee Bean Extract Diet a new revolutionary option to lose weight or just another hocus pocus trick to get inside your wallet?


Losing weight is not an easy task.

That’s why people have turned to all types of supplements, not to mention magic, to ease the burden.Green Coffee Bean Extract Diet

Green Coffee Bean Extract is another one; As of now, it is the world’s most popular weight loss supplement marketed.

As the name suggests, They extract this supplement from green coffee beans, which contains Chlorogenic Acid, a substance that seems to act for weight loss effects.

Green coffee was promoted by Dr. Oz, an American TV doctor, and famous diet guru, back in 2012.

As much as a fan can be excited about a new product, people could always hope for the best and, yet, must prepare for the worse, when it comes to weight loss supplements. They rarely work as advertised and may even present some danger sometimes.


What Is the Stuff?

Coffee beans are naturally green seeds of coffee that when just harvested, lose their color and become pale with time. Before that, they are roasted (into brown color) for brewing consumption.

Active Pharmaco-stuff and antioxidants pack up in coffee beans. Caffeine and Chlorogenic Acid being the most important.

Some people, like Dr. Oz, believe that Chlorogenic Acid is the main active component in green coffee beans to promote weight loss.

The roasting process, sadly, removes the acid and natural roasted coffee grains won’t have the same dieting effect.

(Please, don’t let that keep you away from the wonderful pleasures of drinking coffee)

In the end, green coffee is the same as regular roasted coffee beans, with an added (not-subtracted, actually) boost of Chlorogenic Acid. Fortunately, I don’t see much danger here.


How Does The Green Coffee Bean Extract Diet Work?

Caffeine can boost your metabolism a bit (3-11%), but the main active ingredient is chlorogenic acid.

Some studies with humans propose that it reduces sugar absorption, thus lowering insulin spikes.

According to that, green coffee bean extract intake would act like eating a bit fewer carbohydrates.

Studies with mice show that chlorogenic acid promotes body weight loss, reduces fat absorption and storage in the liver. It can also enhance the fat burning hormone adiponectin functionality and drastically improve cholesterol and triglyceride levels.

Fundamentally, green coffee inhibits weight gain in animal studies.


What About Human Studies?

Numerous studies have related meaningful weight loss in people taking the substance. Those studies are called Random Controlled Trials, a standard of scientific experiments in humans.

Groups drinking instant coffee with green coffee bean extract lost three times the weight, and five times fat percentage, when compared to groups taking plain instant coffee.

The beneficial effect on carb/sugars metabolism could also have an important protective role for diabetics.

Green coffee can also improve blood vessel functionality, which has significant implications for heart health.

Nevertheless, it’s important to remember that companies, that profit from sales of green coffee beans, sponsored some of these studies.

Does that kind of sponsorship necessarily compromise those studies? Not as a rule, but the funding source can have a significant effect on the outcome of a study.

Being extra skeptical is not a bad idea with industry-funded research.


Use and Effect

According to the limited evidence available, green coffee bean extract appears to have a pretty good safety profile.
However, some participants dropped out of one study due to headaches and urinary infection. Those events are too isolated to indicate a connection with the supplement itself; Could be a coincidence.

When consumed in large amounts, coffee is well known for some caffeine side effects like anxiety, jitteriness, rapid heartbeat, etc. Being green, in this case, does not relieve that.

Chlorogenic acid may also cause diarrhea, working as a laxative.

If you are allergic to coffee, avoid it.

There is no guarantee that green coffee is safe for pregnant,  nor breastfeeding women, neither should it be consumed by children.

No study has yet determined the best amount of green coffee bean extract dosage and concentrations of the extract vary from brand to brand.

Try to follow the instructions on the bottle, as usual. A standard recommendation is one serving, 30 minutes before each meal.


My Personal Experience with the Green Coffee Bean Extract Diet

Living in a town that is surrounded by coffee farms, I have easy access to good quality Brazilian green coffee. This way, it was very easy for me to run a NON-SCIENTIFIC experiment.

I grabbed a few pounds of green coffee and ground it into a flour-like powder. Then I distributed the stuff and told my friends to try consuming it three times a day; half a teaspoon each time.

After a while, some results seemed visible. Let’s see what I came up with:

  • Ogres don’t benefit from green coffee whatsoever.
  • People with a fast metabolism may benefit a bit from the stuff, but… Hey, why waste the money if you are already able to lose weight easily?
  • People that have slow metabolisms and have a real hard time losing weight even on a diet can boost a weight loss start-up and benefit from green coffee.
    • One of my employees lost around 25 pounds, but she was that type of person that used to eat very little and could not lose weight at all. My green coffee flour worked wonders for her. Even after stopping using it, she is keeping her weight at a desirable level.
  • Green coffee seems to work well as a boost to well-balanced diets and exercise.
  • And last, but not… well, maybe least: The taste is awful!

Keep in mind, though, that this is just a feeling of mine and no science was involved in the experiment. Lol



After all that, I suppose green coffee extract is worth a shot if you are curious about it.

It might have some effect that can persist for a while, but I wouldn’t expect anything beyond that.

Losing weight is a marathon, not a sprint… and quick fixes never work in the long-term.
