Potential Benefits Of Using Green Coffee Bean Extract For Weight Loss

By Cindy Davis


Coffee houses have recently introduced a new cold beverage. Currently available in either lime or raspberry flavor, it is offered as a way to recharge and refresh. One of the key ingredients in this new beverage is green coffee bean extract (GCBE). In some circles, the use of green coffee bean extract for weight loss is becoming popular.

There is a group of scientists in Scranton, Pennsylvania, who have been conducting research since 1998 into the benefits of drinking hot beverages like coffee and tea. In Spring 2012, they presented results indicating that the compound in GCBE that aids weight loss is a chemical cousin of chlorophyll. It is called chlorogenic acid. Subjects in their study experienced an overall loss of 16% body fat.

The mechanism by which chlorogenic acid is thought to promote weight loss is through slowing the rate of glucose absorption, forcing the body to utilize stored fat instead as an energy source. When the body start to break down its fat stores for energy, weight loss does happen faster. Skeptics attribute this effect to caffeine rather than chlorogenic acid. GCBE only contains half the caffeine as a strong cup of coffee.

People have been trying weight loss remedies since the second century. The Greek physician Soranus of Ephesus could be described as the world's first bariatrician (weight loss specialist). He employed a combination of purgatives, laxatives, exercise, heat and massage. These formed the basis of treatment for more than a thousand years.

The next big trend in weight loss was amphetamines. These were found in the 1930s to be good at appetite suppression. These drugs were later discovered to have dangerous side effects, such as cardiotoxicity and addiction. After they were connected to a series of deaths in the '60s, they were banned from use.

For a while in the 1990s, a drug called Fen-Phen was fashionable with physicians and their patients as a treatment for obesity. It was named after its two active ingredients, fenfluramine and phentermine. This, too, proved dangerous and was withdrawn from the market in 1997 because of its connection with pulmonary hypertension and damage to heart valves.

At the beginning of the twenty-first century, a promising new drug called Ephedra became the weight loss treatment of choice (named after Soranus, the Ephesian, maybe). Linked to stroke, hypertension and death Ephedra was withdrawn from the market.

Green coffee bean extract for weight loss an emerging new trend and it may well turn out to be safe and effective. However, potential users should exercise caution and, at the very least, consult a medical professional before embarking on a course of treatment that contains green coffee bean extract. Nothing, not even water, is completely safe in too high a dose. The extract from green coffee beans contains thousands more chemicals besides caffeine and chlorogenic acid and their effects have not yet been demonstrated. Commercial preparations contain as much as 800 mg per capsule.
