How Do Green Coffee Beans Work?

We have written about green coffee beans, how one might lose weight with green coffee beans, how to get wholesale green coffee beans and organic green coffee extract. And later we reported on a bogus green coffee extract claim. Unroasted green coffee beans have a higher level of chlorogenic acid and that is what is believed to be the benefit of green coffee. Chlorogenic acid is believed to help reduce high blood pressure and people take it for obesity, diabetes, high blood pressure, Alzheimer’s disease and bacterial infections. It is the extract of green coffee beans that people take for medicinal purposes.

For Weight Loss

There is evidence in human testing that chlorogenic acid can reduce the absorption of carbohydrates from the intestinal tract which in turn lowers blood sugar levels and the insulin spikes associated with rapid intake of sugars. In essence to the degree that this works out it is like going on a diet by fooling your body into absorbing fewer calories.

Lower Cholesterol

Chlorogenic acid dramatically reduces cholesterol and triglyceride levels but this evidence comes from studies on rats.

Weight Loss

There is evidence that taking green coffee extract can result in moderate weight loss over a short period of time. However, the study on people only lasted for three months and resulted in a six pound greater weight loss in folks taking green coffee extract versus placebo. There is no evidence that this effect lasts and no research into long term use of green coffee beans or extract for weight loss.

Effect on Diabetes

We know that coffee consumption reduces the incidence of type II diabetes. But is also seems that chlorogenic acid may also have a protective effect as well. In rat studies chlorogenic acid supplements reduce glucose absorption.

Blood Pressure

There is evidence that chlorogenic acid taken daily lowers high blood pressure. Researchers compared chlorogenic acid with placebo in patients with mild high blood pressure and found that both systolic and diastolic blood pressures decreased significantly so long as the patient continued the regime.

What Green Coffee Does Not Do

As we noted in our bogus green coffee extract claim article, manufactures cannot claim long term success in promoting this product for weight loss.

The Federal Trade Commission has levied a fine of $3.5 million on Applied Food Sciences, the company that sponsored the study claiming that green coffee extract resulted in weight loss. Here is a quote from the FTC

the study’s lead investigator repeatedly altered the weights and other key measurements of the subjects, changed the length of the trial, and misstated which subjects were taking the placebo or GCA during the trial. When the lead investigator was unable to get the study published, the FTC says that AFS hired researchers Joe Vinson and Bryan Burnham at the University of Scranton to rewrite it. Despite receiving conflicting data, Vinson, Burnham, and AFS never verified the authenticity of the information used in the study, according to the complaint.

Despite the study’s flaws, AFS used it to falsely claim that GCA caused consumers to lose 17.7 pounds, 10.5 percent of body weight, and 16 percent of body fat with or without diet and exercise, in 22 weeks, the complaint alleges.

The point of all this is that researchers in India fudged the results of their study and no one followed up. This was a bogus green coffee extract claim and should be ignored. If you purchased any green coffee extract for the purpose of losing weight you may want to ask for, or demand, your money back.
