A lot of us know just how difficult it can be to lose weight, and most of us fail in the end. As a result, a lot of us seek ways to lose weight that require the least amount of effort. One of these ways is through the use of supplements with miraculous weight loss claims. One such supplement making the rounds is green coffee bean extract.

Green Coffee Bean Extract is a weight loss supplement that has grown in popularity in the last few years.

This weight loss pill is manufactured using extracts derived from raw, unripe coffee beans.

The weight loss benefit of this extract is attributed to the Chlorogenic acid content of green coffee beans (GCB).

This weight loss supplement became very popular when the American TV show host, Dr. Oz featured it on his show a few years ago.

Most people who have tried losing weight by taking weight loss pills in the past would testify that most never work, and if they do cause any weight loss at all, it is not to the extent of the claims in the marketing materials.

Most of you want to know if a supplement works before buying it, so it is not a surprise that you stumbled on this unbiased green coffee bean review.

We explore all aspects of Green Coffee Bean Extract in this article, including answers to questions like what is it? Does it work and if so how does it work? We reveal what the scientific evidence says about GCB.

What is Green Coffee Bean Extract?

Green coffee bean extract from raw beans

The name pretty much tells you what it is. Green coffee beans are raw, unripe coffee beans.

Coffee beans are high in potent antioxidants and several other beneficial plant compounds. Chlorogenic Acid and Caffeine the most abundant compounds in coffee beans. However, most of us may only have heard of caffeine.

Green coffee bean extract is an extract from raw coffee beans. The main active ingredient in this supplement is chlorogenic acid, which is claimed to responsible for the weight loss benefit (a).

The regular coffee you buy from the store to brew at home contains very little chlorogenic acid because the roasting process destroys most of it (b).

And yet many people still claim that drinking regular coffee may also produce weight loss benefits. There’s even a weight loss diet out there known as bulletproof coffee, which suggest combining coffee and butter to help you lose weight.

Conclusion: Green coffee beans at raw coffee beans that have not yet been roasted. They contain high amounts of chlorogenic acid, a substance that is believed to cause weight loss.

How Green Coffee Extract May Cause Weight Loss

Research indicates that the caffeine content of green coffee bean extract can increase the rate of metabolism by as much as 12% (c, d).

But caffeine is not the primary active ingredient in GCB. Chlorogenic acid is more abundant in GCB than caffeine.

The research suggests that chlorogenic acid may help lower the number of carbs the body absorbs from the intestine. This may help lower blood sugar levels and prevent insulin spikes after meals (e, f).

This means that green coffee bean extract may have a similar effect as a low-carb diet.

An animal study revealed that chlorogenic acid might help you lose weight, inhibit the absorption of fat, and improve the body’s ability to burn fat (g).

A different animal study also showed that chlorogenic acid might help reduce the levels of triglycerides and cholesterol in the blood, which reduces the risk of obesity (h).

Conclusion: Available evidence suggests that green coffee extract may cause weight loss by restricting how much carbohydrate your body absorbs your intestines. It may also improve the levels of triglycerides and cholesterol. The caffeine content may also boost your body’s rate of metabolism, which will make you burn more calories than you normally would.

Does Green Coffee Bean Extract Work?

Despite the claims, there aren’t many scientific studies on the weight loss abilities of chlorogenic acid, which is the active ingredient in this supplement.

However, the results of one study suggest that green coffee bean extract may potentially help you lose weight (i).

A different study looked at the effect of this extract on the weight of a group of 30 obese people. The participants were separated into two groups. One group drank instant coffee with 200 milligrams of pure green coffee bean extract, while the other group drank on instant coffee (j).

Both sets of groups made no changes to their regular diet or activity level.

The participants in the green coffee group lost an average of 12 pounds during the 3-month trial, while those in the other group lost an average of 3.6 pounds.

The result also showed that participants in the green coffee group lost an average of 3.5% of their body weight while those in the other group lost an average of 0.8%.

Other trials

A few other scientific trials have shown promising results (k).

However, we have to be cautious about these studies because a lot of them are funded by entities in the green coffee bean industry.

And although this does not automatically mean that the research is biased, we know that some industry-sponsored studies have a way of producing results that favor them (l).

One scientific study reviewed the evidence on the effects of green coffee bean and concluded that, although they show promise, most of the studies were very poorly designed. It demanded that new studies be carried out to properly examine the benefits of GCE for weight loss (m).

When you read reviews from people that claim to have used this supplement, you’ll come across mixed reviews, just like the reviews for other weight loss pills.

Some users swear that it worked for them while you’ll have others on the other end that swear it actually made them put on extra weight.

Conclusion: A few human studies indicate that the claims may be true for green coffee bean extract. However, some of the research is industry-sponsored and involved small groups of participants. Despite all the claims, you may have to try the supplement yourself to find out if it works for you or not.

Other Potential Health Benefits of Green Coffee Extract

Research suggests that chlorogenic acid may have some benefits for people with diabetes. It may reduce the amount of glucose absorbed from the foods we eat, which may be beneficial for people with diabetes (n).

This effect of chlorogenic may also translate into weight loss.

Other studies show that taking green coffee extract may also help reduce blood pressure in people with hypertension (o, p).

The extract also contains potent antioxidants like chlorogenic acid, which can help lower the risk of disease (q).

Conclusion: There may be other health benefits from taking green coffee bean extract. It may help lower blood pressure, and improve symptoms for people with diabetes.

What is the Dosage, Potential Side Effects, and How do I Use it?

Current evidence indicates that it is mostly safe to take green coffee bean extract. This is not to say that there are no side effects. There are a few reported side effects, but there are no serious or fatal adverse effects.

GCB does contain caffeine, which is known to cause a few side effects like increased heartbeat, restlessness, anxiety, etc.

In addition, the chlorogenic acid in green coffee bean extract may induce diarrhea and may have a laxative effect on you (r).

There have also been a few reports of people experiencing allergic reactions after taking green coffee bean extract. People who experience allergic reactions to coffee should avoid taking GCB (s, t).

We don’t know the effects of green coffee extract on pregnant and lactating women and their babies so you may want to avoid it to be on the safe side.

What about a safe dosage?

At this time, there is no scientifically recommended dosage for this weight loss supplement, but the studies we mentioned used a daily dose of 250 to 3,000 milligrams of the extract.

However, most manufacturers include recommended dosages with their product, and you should stick to those.

Most recommend that you take the supplement about half an hour before eating.

Final Thoughts

We do not recommend weight loss pills as a solution to weight problems. The best way to lose weight is by maintaining a healthy lifestyle that involves eating healthy foods and being active.

So, even though green coffee bean extract may help you lose weight, it will not solve your weight problems if you don’t make the necessary lifestyle changes.

We recommend incorporating green coffee beans into a holistic weight loss program that involves diet and exercise to get the maximum benefits.

You should also consult your doctor before you start taking any weight loss supplement.
