Green coffee extract is exactly as it sounds, a supplement extracted from green coffee beans for the purpose of making weight loss supplements’. Green coffee beans are simply unroasted coffee beans, when roasted the coffee beans lose their chlorogenic acid value, which is believed to be the compound responsible for weight loss properties. As with other fad weight loss supplements’, the interest in green coffee as a weight loss supplement skyrocketed after being mentioned on national TV for its weight loss properties. The big question is; does it really work or is it just another weight loss trend that is too good to be true?
If you scan an isle of diet pills and supplements, you are sure to fine a ton of weight loss supplements that claim to be the miracle solution. Green coffee extract is sure to be right there among the others. While the claims that green tea extract can aid in weight loss have only been vaguely studied; the studies that have been don’t aren’t exactly a strong suit for the argument of if it being that the miracle weight loss supplement that it has been made out to be.
According to, the National Library of Medicine, the original study that was cited when green coffee extract made its claim to fame on nation TV, was retracted as of July 2014. The original study stated that test subjects showed significant reductions in body weight, body mass index, and overall percent of body fat; as well as a small decrease in heart rate. All results were noted to be found with no significant changes to diet over the course of the study. It was concluded that the results were consistent with human and animal studies and a meta-analysis of the efficiency of green coffee extract in weight loss. The results showed that green coffee extract may be an effective nutraceutical in reducing weight in adults and may be an inexpensive means to preventing obesity.
According to, Fox News, the article was retracted due to the authors being unable to validate the claims that were being made. The retraction of the original study doesn’t necessarily mean that there is no benefit on weight loss from green tea extract; it does, however, mean that there isn’t enough evidence to support its sudden claim to fame. Green coffee extract, is by no means, an instant miracle weight loss supplement that will answer all of your weight loss needs. While it may still be healthy and beneficial, it is extremely important to speak with your primary care physician before starting any over the counter medications and supplements.
It is believed, that this is one of the main reasons that the evidence based on the above study was retracted. Green tea extract received an instant overnight boost in popularity just by being mentioned on an acclaimed television show. For that reason, people began rushing out to purchase it based on the one study noted. While it is believed that green coffee extract can be beneficial for weight loss, type 2 diabetes, Alzheimer’s disease, and high blood pressure; there is still no research supported evidence to validate any of the popular claims.
