Green coffee bean extract was widely promoted by Dr. Mehmet Oz as a miracle supplement for weight loss. Originally, Oz cited a weight loss study that claimed people who used green coffee bean extract lost 16 percent of their body fat. However, under scrutiny by federal regulators, the study, which was published in the
National Institutes of Health, was later retracted because the data could not be validated.
Although the data is limited, there have been scientific studies on the effects of green coffee beans on metabolism and blood sugar management as it relates to diabetes.

The American Chemical Society published a 2013 report that indicated green coffee beans extract was beneficial to help control elevated blood sugar. According to lead researcher Joe Vinson, Ph.D, "All doses of green coffee extract produced a significant reduction in blood sugar relative to the original blank glucose challenge. The maximum blood glucose occurred at 30 minutes and was 24 percent lower than the original with the 400 mg of green coffee extract and the blood glucose at 120 minutes was 31 percent lower,"
reports Science Daily.
The Natural Medicine Journal published a 2013 "review and meta-analysis of available randomized clinical trials examining the effects of GCBE supplementation on weight loss in both normal weight and overweight/obese individuals." Researchers concluded that green coffee bean extract may be effective in promoting weight loss in obese subjects but did not have the same effect in normal weight individuals.

The American Chemical Society reported on an additional study in 2013. "A major ingredient in those green coffee bean dietary supplements — often touted as "miracle" weight-loss products — doesn't prevent weight gain in obese laboratory mice fed a high-fat diet when given at higher doses. That's the conclusion of a first-of-its-kind study published in
ACS' Journal of Agricultural and Food Chemistry. It also linked the ingredient to an unhealthy build-up of fat in the liver."
According to the Federal Trade Commission, self-proclaimed naturopathic doctor, Lindsey Duncan, who appeared with Dr. Oz to tout the benefits of green coffee bean extract, falsely marketed the supplement. Jessica Rich, Director of the FTC's Bureau of Consumer Protection says, "Lindsey Duncan and his companies made millions by falsely claiming that green coffee bean supplements cause significant and rapid weight loss. This case shows that the Federal Trade Commission will continue to fight deceptive marketers' attempts to prey on consumers trying to improve their health."
