Inhibits the release of glucose in the body boosts the metabolism and "burns fat". Coffeetrim by hi-tech pharmaceuticals utilizes only the best raw material standardized to 50% chlorogenic acid and 65% polyphenols. A recent study on green coffee bean for 12 eweks lost an average of 17 pounds each-this was 10.5% of their overall body weight and 16% of their overall body fat. The key to this incredible weight loss is not attributed to the caffeine. The key ingredient in the green coffee bean is called chlorogenic acid. Chlorogenic acid works the by inhibiting the release of glucose in the body, while at the same time boosting the metabolism or the "burning" of fat in the liver. These two mechanisms work together to inhibit the absorption of fat and eliminate weight gain.
