You might have heard of the miraculous weight loss abilities of green coffee extract (the extract of unroasted green coffee beans). It is found in a myriad of slimming supplements including, FatKiller, one of the best selling slimming supplements on the market.
While it has been promoted heavily on the media, appearing on famous doctor shows, actual scientific evidence supporting its weight loss abilities is lacking. In fact, in 2012, a featured guest in a well-known TV show, Lindsey Duncan, touted the abilities of green coffee extract as a miracle weight loss supplement. Lindsey Duncan was subsequently fined $9 million by the Federal Trade Commission (FTC) for “falsely claiming that green coffee bean supplements cause significant and rapid weight loss.”
What do studies have to say about green coffee extract? In 2011, a review found tentative evidence that green coffee extract promoted weight loss. However, the evidence was poor and the review claimed that the three trials that were conducted (with a total of 142 participants) showed a small effect and furthermore, the participants were also asked to limit their diet and increase their exercise. You could eat donuts and exercise more and claim that donuts are the reason for your weight loss…
In 2014, another trial that showed the benefits of green coffee extract was retracted and the sponsoring company, Applied Food Sciences, was fined by the FTC for making unfounded weight loss claims in their study. The good news is that no adverse effect has been linked with taking the extract, so you don’t risk anything by trying it.
