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.
Biochemists in Pennsylvania have been studying the health benefits of tea and coffee since 1998. At a meeting of the American Chemical Society in San Diego, they presented evidence that the molecule in GCBE that may be responsible for weight loss is chemically related to chlorophyll. Its name is chlorogenic acid. Participants in the study experienced an overall decrease of 16 percent body fat.
The mechanism by which chlorogenic acid is believed to promote weight loss is by reducing the rate of glucose absorption from the bloodstream, forcing the body to turn instead to stored fat as a source of energy. This is thought to result in a more rapid rate of weight loss. Skeptics believe the observed weight loss is attributable to caffeine as opposed to chlorogenic acid. Green coffee extract, however, has half the caffeine concentration as that found in a strong cup of coffee.
Keeping weight down to healthy levels has confounded people for thousands of years. The second-century Greek doctor, Soranus of Ephesus, could easily be regarded as the father of bariatrics, the science of weight loss. He prescribed laxatives, exercise, purgatives, heat and massage. These were the weight loss aids of choice for over 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 This, too, proved dangerous and was withdrawn from the market in 1997 because of its connection with pulmonary hypertension and damage to heart valves.
Ephedra was the next trend in weight loss at the beginning of the 21st century. It is tantalizing to speculate that this was named in honor of the good doctor Soranus, from Ephesus. Eventually, Ephedra became linked with high blood pressure, stroke and deaths and was banned from use.
However promising the emerging data concerning green coffee bean extract for weight loss may appear to be, GCBE should be used with caution. All drugs are 'dirty' and have harmful side effects at high doses or over time. Drinking water in too high a concentration can be fatal. Green coffee bean extract contains thousands of different chemicals. Not all of them have been as thoroughly characterized as caffeine and, to a lesser extent, chlorogenic acid. Some of the GCBE preparations currently available over the Internet contain as much as 800 milligrams of coffee extract. People considering using this dietary supplement as an aid to losing weight should certainly consult their medical adviser. Enjoying the occasional refreshing, revitalizing iced beverage should be harmless to most people.
