Is It Safe to Consume Green Coffee Bean to Lose Weight?

On one of The Dr Oz Show episodes, green coffee beans were recommended as a supplement to help with weight loss. Since then it has become a coveted health food among those looking to lose weight naturally.

Green coffee bean extract comes from non-roasted coffee beans and contains compounds known as chlorogenic acids. Because of this acid, it’s believed that the beans offer anti-oxidant effects which help to manage blood pressure as well as lose weight. While normal coffee beans contain them too, chlorogenic acids are usually removed when the beans are roasted, hence they are believed to be less effective in aiding weight loss.

Some of the weight loss effects associated with chrologenic acid include:

  • Reducing fat stored in liver
  • As it contains caffeine, it can boost metabolism
  • It also decreases the absorption of carbohydrates, which inhibits weight gain

However, whether it works or not to help us lose weight, there is very scant evidence as many studies done only involve very few people. For instance, in a 2012 study, many were bewildered that subjects who had taken 1,050-mg and 700-mg doses managed to lose a whopping 16 pounds in six weeks compared to another group who was taking placebo doses. While it did make headlines, the study wasn’t widely accepted as it was only participated by 16 people and funded by a green coffee bean extract manufacturer. Later on, scientists evaluated three random clinical trials which totaled up to 142 subjects and concluded that using green coffee extract to lose weight offers only moderate results.

In a nutshell consuming the extract at moderate levels is relatively safe; and in combination with a healthy diet and exercise, it may help you to shed some pounds. However, it’s better to be cautious of taking too much of it – chlorogenic acid may increase the risk of heart disease as it raises the levels of the amino acid, homocysteine. To be on the safe side, take no more than 3 cups a day (300-400 mgs), and have it along with healthy foods.

    Dr Oz has a good track record and there benefits
    chrologenic acid include:reducing fat stored in liver, it contains caffeine, it can boost metabolism, it also decreases the absorption of carbohydrates, which inhibits weight gain.

    With one study perhaps perhaps another could have better results. Regardless it is still in the beginning stages though.

    Good read. What do you think of the results?

  3. Those green coffee beans remind me of my parents farm. They use to plant coffee, but we never pick it green. It had to be cherry ripe for picking. I guess coffee was not sold green back in those days. I am skeptical about green coffee beans having weight loss benefits. Do you think the red coffee beans could work for weight loss too?

  4. I really enjoyed reading the pros and cons about the coffee as a weight loss possibility. I like your website because you show more than one possibility to lose weight. I enjoyed looking at the different yoga poses. I really liked your site a lot. You provided a lot of information on the different topics you shared on your website. I especially liked the back and forth that you did on the green coffee beans. And also by pointing out that the study done only involved 16 people and only 16 pounds was lost. I hope that this comment helps encourage you and helps you strive to blog about different topics in a similar way.

  5. Great information! I actually didn’t even know anything about green coffee beans. I know I appreciate your honesty of the effectiveness of green coffee beans. Just in my opinion, I don’t think I would use green coffee beans to help me lose weight, but you never know I might give it a try. Thanks again for sharing!

  6. I’ve always believed that coffee helps in weight loss, because it has antioxidants and caffeine that helps make metabolism faster. It is my first time though to have heard about green coffee, which makes it more interesting! Because of your post, I found out that green coffee is better since the green part is removed when coffee beans are roasted. Thanks for this informative article!

  7. I have heard that regular dark coffee has the effect of energizing out metabolism. I didn’t realize that there was such a thing because coffee has always been known to be roasted too me. The green coffee effect sounds a little bit too good to be true since the study was fine by a small group. Small amounts along with the right lifestyle like diet and exercise should create wonderful effects. The homocysteine sounds like a bit of a problem because it is closely related to inflammation. However, everything in the world can cause a problem if you overdo it so just use a little common sense. IW app give it a try. It sounds refreshing. Do you grind and be it like regular coffee beans?
