Green Coffee Bean Extract Tested On 'Dr. Oz Show'

Green Coffee Bean Extract on "Dr. Oz Show"

"The Dr. Oz Show" has once again featured the weight-loss supplement pure green coffee bean extract.

Under the guidance of health experts, the show conducted a project to test the effects of the green coffee bean extract.

The project involved 100 female participants, ages of 35 and 49, who were overweight with BMIs between 25 and 45. None of the women were pregnant, breastfeeding nor having any major medical problem. They either received the green coffee bean extract or a placebo, and were instructed to take 400mg capsules, thrice a day – half an hour before each meal. They were not informed which pill the were given and were instructed not to change their diet and to keep a food journal. Their weight were then measured two weeks after.

According to the show's own study, the group of women who took the green coffee bean extract lost, on average, two pounds. However, the group of women who took the placebo lost an average of one pound – "possibly because they were more aware of their diet for that two weeks because of the required food journal."

In April, "The Dr. OZ show" presented the results of a study wherein test subjects lost an average of 17 pounds in only 12 weeks of supplementation without any changes to diet or exercise with zero side effects. The results were also published on the Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy.

Pure green coffee bean extract's active component called chlorogenic acid is being attributed with the subjects' weight-loss. The natural compound is believed to work by slowing down the release of glucose into the body after meals while at the same time boosting metabolism. These two mechanisms work together to inhibit the absorption of fat and eliminate weight gain.

Chlorogenic acid is not present in aromatic roasted familiar version of brown coffee since it is removed during the roasting process (which is done at over 400 degrees Fahrenheit) as the acid is extremely bitter.

The green coffee bean supplement also has lower caffeine than a cup of coffee. It has only around 20 mg of caffeine per serving compared to 100 mg per cup of coffee.

In some studies, the bean has also shown to help lower blood pressure – while still boosting metabolism.
