On a recent episode of Dr. Oz, green coffee bean extract was a topic of discussion for use in aiding weight loss in adults. Since this episode aired, green coffee bean extract has been one of the most popular search engine topics and Starbucks has even added it to one of their “low calorie” drinks to promote a claim of a “natural energy boost”.
Green coffee beans are simply coffee beans that have not yet been roasted. Coffee is typically made from roasted coffee beans because it taste better, but the process also eliminates chlorogenic acid. Chlorogenic acid is a polyphenol antioxidant that researchers speculate may promote weight loss by reducing the absorption of fat and glucose in the gut, and lowering insulin levels to improve metabolic function. When you roast coffee beans to eliminate the bitter taste, you also eliminate chlorogenic acid. Therefore, the theory of extracting the green coffee bean before it is brewed would result in a higher content of chlorogenic acid.
According to a new study using the extract, participants lost an average of 17.5 pounds in 22 weeks. When Oz did his own study he found that dieting participants lost an average of two pounds per week when taking the extract while those who did not lost an average of only one pound a week.
Dr. Oz said he would not endorse any of these products because he didn’t want his name associated with it, but suggested people should look for green coffee beans extract with at least 45 percent chlorogenic acid. The recommended dosage was 400 mg and suggested the supplement should be taken 30 minutes prior to each meal. When looking at the green coffee bean supplement ingredients, chlorogenic acid can be listed as GCA (green coffee antioxidant) or Svetol.
While the supplement appears to be safe, more research needs to be done before recommending green coffee bean extract for weight loss as well as examine long term effects from taking the supplement. Like anything else, always consult with your Medical Doctor prior to taking any supplements such as green coffee bean extract.
