Green Coffee Beans aid Weight Loss?

Ground green coffee beans taken daily; seem to spur steady weight loss, according to new research. Scientists report striking new evidence that green or unroasted, coffee beans can produce a substantial decrease in body weight in a relatively short period of time.

In a study presented at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society, Joe Vinson, Ph.D., and colleagues described how a group of overweight or obese people who consumed a fraction of an ounce of ground green coffee beans each day lost about 10 percent of their body weight.

Taking multiple capsules of green coffee extract a day – while eating a low-fat, healthful diet and exercising regularly – appears to be a safe, effective, inexpensive way to lose weight,  The study involved 16 overweight or obese people aged 22-26 years who took capsules of the extract or capsules containing a placebo, an inactive powder, for a total of 22 weeks. The subjects alternated between a low dose and a higher dose of the extract. The low dose consisted of 700 mg of the coffee extract, and the high dose was 1,050 mg. It was a so-called “cross-over” study in which people cycled through the two doses and the placebo, each for six weeks. Such studies have advantages because each person serves as his or her own “control,” improving the chances of getting an accurate result.

The participants were monitored for their overall diet (calories, food eaten, etc.) and exercise. Participants lost an average of 17 pounds during the 22 weeks of study. It included an average of a 10.5 percent decrease in overall body weight and a 16 percent decrease in body fat.

Green coffee beans’ effects likely are due to a substance called chlorogenic acid that is present in unroasted coffee beans. Chlorogenic acid breaks down when coffee beans are roasted (usually at a temperature of 464-482 degrees Fahrenheit). Roasting gives coffee beans their distinctive colour, aroma and flavor. Green coffee beans, in contrast, have little aroma and a slightly bitter taste.

Overweight and Obesity subjects in the US are now 68% of the population. We have investigated an extract of green (unroasted) coffee beans high in coffee polyphenols. A 22-week cross-over study was conducted in 16 sub-obese adults to examine the efficacy and safety of a commercial product GCA™. Subjects receive a high-dose (1050 mg), low-dose (700 mg), and placebo in separate six-week treatment periods followed by two-week washouts. Primary measurements were body weight, body mass index (BMI) and fat mass (BIA). Heart rate and blood pressure were measured. There was a significant decrease (improvement) in all parameters except blood pressure. Weight loss averaged 8 kg without side effects.

Green Coffee Beans is a safe, effective, and inexpensive nutraceutical for weight loss.
