The popularity of green coffee declined sharply in 2015
Green coffee gained notoriety as a weight loss supplement thanks to a marketing campaign deployed by Dr. Oz on his show in 2012. Dr. Oz claims that green coffee promotes rapid fat burning, even without dieting or exercising. A similar "publicity explosion" has been seen with goji berries and ginger.
"Warning" Most experts agree that the research results provided by Dr. Oz are unreliable, and the popularity of the supplement is due to widespread advertising propaganda. In Russia, green coffee supplements began to be actively marketed in 2013 on the principle of network marketing, hundreds of sites and social groups have been created.
Green coffee extract is an extract of unroasted green coffee beans. The extract is used as a dietary supplement for weight loss and as an ingredient in other weight loss products. Its efficacy and mechanism of action are also the subject of debate. There is evidence of a positive effect, but the evidence is unreliable. The extract is sold under various trade names, including Svetol, and is also included in weight-loss products such as Coffee Slender.
In April and September 2012, the Dr. Oz Show demonstrated green coffee extract and conducted its own non-scientific study to prove its effectiveness.
Svetol was developed by Berkem, a French phytochemical company specializing in plant extracts. The product first entered the market as a dietary supplement in 2002. By 2005, it became the active ingredient in CoffeeSlender, a popular weight-loss product in Norway, and the product was released in the UK the following year. At the 2006 European Healthy Ingredients Conference, it won a bronze award in the best ingredient categoryIn January 2008, NATUREX, an international manufacturer of natural ingredients, acquired Berkem's plant extracts division, of which Svetol was the main product and brought Svetol to the US market.  Svetol is one of only two brands of green coffee extract with a standardized chlorogenic acid content of at least 45%
In 2013, EuroPharma included Svetol in its range, claiming that it shows "one of the most impressive results in clinical trials. As of 2013, Svetol is the number one weight loss product in the U.S. and is used in 100 co-branded products in North America.
A 2011 review found preliminary evidence that green bean extract promotes weight loss, but the quality was poor. This review looked at the results of three published randomized controlled trials, involving 142 people, and found little effect. The review noted that more rigorous and longer studies are needed to evaluate the efficacy and safety of green coffee as a weight-loss treatment
The Federal Trade Commission accused Florida firms manufacturing a product called Pure Green Coffee of deceiving consumers with false claims of weight loss. The Commission stated that Vinson's research was not credible because serious methodological flaws made its results unreliable
On June 17, 2014, the Senate Subcommittee on Science and the Transportation Committee held a hearing to discuss weight loss products and consumer protection. During the hearings, green coffee extract was often cited as an example of a "pacifier" product being sold to consumers. When Dr. Oz defended green coffee extract and other weight loss products on his show, Senator McCaskill stated that "the scientific community is almost unanimous against you on the effectiveness of the three products you call miraculous."
During the hearing, Dr. Oz stated:
"I actually believe in the things I talk about on the show. I actively study them. I admit that they don't have a scientific basis that can be presented as fact, but nevertheless, I would give my viewers the same advice that I give my family, and I gave my family these products. Exactly the ones you mentioned, so that's fine with me. "He said he believes in them "as short-term crutches, and even my family has tried them. But there are no long-acting miracle pills without diet and exercise."
