Green coffee for weight loss between truth and fraud, based on the latest scientific research
Green coffee for slimming, as many supplement companies are promoting hundreds of slimming products that contain green coffee extracts.
Green coffee has been associated with slimming, Dr. Oz as he has a famous episode of his show “The Dr. Oz Show, in which he advised his followers to take green coffee to lose weight. I will remember the story of this episode and its relationship to the questioning of Dr. Oz in Congress because of it.
I have hundreds of messages about the use of green coffee for weight loss, but some supplement companies have sent me to advertise green coffee products on the site, and this was a great motivation for me to write this article and show many facts about these supplements.
In this article, I will cite the latest studies and scientific research conducted on green coffee for slimming
I wrote a previous article about a quick comparison between green tea and green coffee for slimming and this is the link to the article
Green tea or green coffee for weight loss
What is the difference between regular coffee and green coffee for slimming?
We all heard about the old controversy talking about coffee in general and conflicting opinions about its use and its relationship to preventing many diseases.
Coffee in general is a popular drink spread in most countries of the world
Studies indicate that roasting green coffee beans to obtain black coffee may reduce the amount of caffeine in it, but it is possible that the percentage of loss is minimal.
I wrote a previous article that I mentioned in a lot of scientific research about the benefits of drinking coffee, the appropriate amount and the best time to take it. You can refer to this article from the following link
The benefits of coffee
Green coffee is the same coffee bean used for "black" coffee, but before it is roasted
Green coffee contains chlorogenic, a substance that is promoted as a substance that helps in slimming, along with its antioxidant effects and its role in lowering blood pressure.
Green coffee beans when roasted to obtain the "used in regular coffee" coffee beans lose most of their chlorogenic content.
The low percentage of this substance in roasted coffee beans is what some people have argued that the effect of green coffee for weight loss is better than the effect of regular coffee.
Despite this, many companies promote green coffee products for slimming, and most of the product's effectiveness is related to the caffeine found in green coffee and not to the chlorogenic substance.
As I mentioned in my article about coffee, caffeine has an effective role in slimming and burning fat
Is green coffee slim?
I will address this with citing research and scientific sources how effective green coffee is for weight loss
There aren't many studies on green coffee for slimming or chlorogenic
Scientists said that green coffee or chlorogenic substance needs more research to know its ability to lose weight or burn fat and lose weight.
When reviewing these studies from the scientists, they found a major deficiency in the method of conducting these studies, in terms of the number of volunteers on whom the study was conducted and also the duration of the studies was insufficient to determine the results.
Scientific studies are not random, but they have foundations and principles for conducting them and measuring their results until their results are taken
What's more, one of these studies was funded by companies that manufacture green coffee extract
This is a comprehensive meta-analysis, which is the most powerful type of studies whose results are based on
"Synthesis studies are considered the final opinion in a group of studies, that is, you analyze most studies on a specific topic, and a group of scholars perform them and give their opinion after this analysis."
Study title is The Use of Green Coffee Extract as Weight Loss Supplements: A Systematic Review and Analysis of Randomized Clinical Trials
A brief summary of this comprehensive study states:
The purpose of the study is to evaluate the effectiveness of green coffee extract for slimming “GCE”.
Evaluation of studies and scientific articles published regarding green coffee extract for slimming
All of the studies included in the study were associated with a higher risk of bias, “that is, the lack of neutrality and bias of these studies for green coffee supplements.
This study said in the text “the studies are all of poor methodological quality”, meaning that all the studies are of poor “bad” methodological quality.
More rigorous testing is needed to evaluate green coffee extract's benefit for weight loss
Link to the meta-study
There are many nutritional supplements and drugs used for slimming, which I talked about in several articles, such as:
Lipo-6, Animal Cut, Orlistat or Xenical, Clenpetrol, and Shitocal
Green coffee for slimming Dr. Oz
On his famous talk show, Dr. Oz examined his followers on the use of Garcinia Cambogia Supplements, Raspberry Ketones and Green Coffee Extract for slimming, "all of them are supplements that claim to aid in weight loss and slimming."
Then Dr. Oz was summoned in the US Congress and blamed for this, and he was accused of deceiving viewers by the chair of the Consumer Protection Committee.
The study that Dr. Oz relied on is an Indian study funded by a company whose products are green coffee extract for slimming
This study was published on the NCBI's National Center for Biotechnology Information website and is part of the National Library of Medicine in the United States
This site is a major source of scientific research which I cite many studies published on in my articles
When searching on this site for this study cited by Dr. Oz, I found that the site had been deleted due to the weakness of this study

Of course in our country there is no accountability for any of the program or channel providers for what they say, but you will find many programs based on promoting green coffee products for slimming and similar products of doubtful effect.
When searching the internet I found this address
How to make green coffee for slimming pictures
And a lot of similar articles spreading rumors and misinformation
Not only are the websites promoting these products, but the producing companies as well
This is not only in the Arab countries, but it is widespread in all countries of the world, especially on the Internet
I also came across this ad on one of the sites
The FTC sued a company for mis-marketing, claiming unrealistic effects about green coffee for slimming.
The Federal Trade Commission is responsible for ensuring that companies do not use misleading language to deceive consumers
Dietary supplements do not need approval from the Food and Drug Administration, unlike drugs that require prior approval before going on the market
The FDA recommends that you be careful with the use of nutritional supplements, especially those claiming to lose weight quickly without changing your eating habits.
Supplement companies write "natural product" to market their products
Do not be fooled, as many natural plants are toxic and may be deadly. Marjouana is a natural plant
All that I mentioned does not mean that there are no benefits to green coffee beans

It may help improve mood
In an Australian study conducted by Swinburne University examining the relationship of drinking decaffeinated coffee, which is rich in chlorogenic acid, and comparing it to regular coffee with improved mood and increased cognition.
The results showed the strong positive effect of regular "black" coffee containing caffeine on mood and cognition
As for decaffeinated coffee, rich in chlorogenic acid, it had less effect, but it also improved mood
Also in the last of the study, the researchers say it requires further investigation

I mentioned all this in my article on coffee, which I put the link at the beginning of the article
As for the harms of green coffee, it may have an effect on the rate of absorption of both zinc and iron minerals, and therefore it is preferable to keep it away from meals rich in these minerals such as meat.
I wrote a detailed article about iron, its benefits and dosages for all ages, symptoms of its deficiency, foods rich in it, and things that affect its absorption.You can read it from the following link

Green coffee may also affect bone health
In a two-month study to find out the damages of green coffee on the bones, this study was conducted on mice, where they were given daily doses of green coffee
As a result of the study, mice were exposed to a deficiency of calcium in bone tissue
This study indicates that consuming green coffee for slimming might damage bones in the long term of use
