Green Coffee beans speed up the fat absorption process by stimulating the activation of fat metabolism in vital organs of the body such as liver, which is a major component in weight reduction. The essence of the Green Coffee Bean extract is the chlorogenic acid, which releases glucose in blood, especially after meals to speed up the process of weight reduction.
The chlorogenic acid found in the coffee beans also enhances the body heat. This promotes thermogenesis, a process where the body naturally burns the fat for energy. The chlorogenic acid due to its superior anti-oxidant effects reduces the generation of new fat cells. This entire process  helps an individual to lose weight and keep it off.

If you are under the impression that you are just going to lose weight with the Green Coffee Bean Extract dietary supplement, then you are completely wrong. This is mainly because; apart from helping you to lose weight, it also provides some other health benefits. For instance, this dietary supplement can contribute to overall good health by preventing damage to DNA caused by the several classes of carcinogenic compounds.                                                    
Furthermore, the Green Coffee Bean Extract dietary supplement also aids in lowering the levels of total plasma homo-cysteine. High levels of homo-cysteine levels in blood are a risk indicator for cardiovascular diseases. By lowering these levels, the bean extract can keep cardiovascular diseases at bay.
The coffee bean extract can also help you in reducing hypertension. The chlorogenic acid in the coffee beans neutralizes free radicals and help regenerate Vitamin E which helps to fight hypertension. The extract also inhibit lipid and LDL degradation, promoting optimal cardiovascular health.

                                                                                                                                                                                                           Several clinical studies have found that the
chlorogenic acid present in the natural coffee beans decrease both systolic and diastolic blood pressure. It also helps in reducing the cholesterol levels in the blood which is major cause behind damage to the arteries resulting into atherosclerosis and stroke. By decreasing the cholesterol levels in the blood, the coffee beans help prevent cardiovascular disease and provide an individual with a healthier quality of  life.
Scientists are reporting striking new evidence from recently published human clinical trials that unroasted green coffee beans can produce a substantial decrease in overall body weight and total body fat in a relatively short period of time without changes in diet or exercise regimen.
It is believed that a natural compound known as Chlorogenic Acid found in unroasted green coffee beans is likely responsible for the positive weight loss effects. Roasting coffee beans at 460-480 degrees Fahrenheit provides the distinctive aroma, color, and flavor we enjoy every morning. However, the roasting process breaks down the Chlorogenic Acid so it is no longer available to help us lose weight. Unfortunately, we can't have our coffee and drink it too.
Numerous studies in the past have shown weight loss with Green Coffee Beans. However, in March 2012, a breakthrough human clinical study was presented at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society. This 22 week study was unique because the test participants from 22 to 46 years old were subjected to three different dosage levels: placebo (no Green Coffee Bean), low dosage, and high dosage. Such studies have advantages since each test subject serves as his or her own "control", improving the chances of getting an accurate result. All the participants were monitored for their overall diet and exercise regimen to ensure no significant change in either during the trial period.
Participants lost an average of 17 pounds during the 22 week study which worked out to be an average of 10.5% decrease in overall body weight and a 16% decrease in total body fat. It was speculated that the weight loss experienced during the study may have been significantly faster had the participants been on the high dosage of Green Coffee Bean for the entire duration of the study, rather than placebo and low dosage.
Unroasted Green Coffee Beans have virtually no aroma and a strong bitter taste so brewing up a batch of Green Coffee Joe is not a very appealing option. Fortunately, Green Coffee Bean Extract is available in high dosage levels in easy-to-take dietary supplements. Green Coffee Beans have been shown to inhibit fat absorption, stimulate fat metabolism, and to activate thermogenic fat burning. It is also a potent antioxidant and has positive effects on healthy blood sugar levels and cardiovascular health. When used in combination with light exercise and a sensible diet, Green Coffee Beans are truly a "Miracle in a Bottle" fat burner.
