Holistic Health: Green Coffee Bean Extract

The craze over green coffee bean extract took over after getting a stamp of approval from Mehmet Oz, MD, known on TV as “Dr. Oz.” Dr. Oz claims that the extract can help women lose weight.

Green coffee beans are simply coffee beans that haven’t been roasted. Regular coffee is usually made from roasted coffee beans because it tastes better. However, roasting coffee beans eliminates chlorogenic acid, which is the component in green coffee bean extract that is said to speed weight loss.

Besides green coffee bean extract, chlorogenic acid is also found in peaches and prunes. It is also used as a preservative in the food industry to inhibit the growth of bacteria.

A recent small study in India gave evidence that the chlorogenic acid is actually effective in weight loss. The study only included 18 people, but overweight volunteers lost more weight than a control group when they took a dose of 700 milligrams or 1050 milligrams of chlorogenic acid. The weight loss occurred without any big changes in diet or exercise.

Dr. Oz did his own study with women in his television audience. After two weeks, those that took green coffee bean extract lost an average of two pounds. Interestingly, the women in the placebo group lost weight as well, though not as much.

The chlorogenic acid in green coffee bean extract appears to interfere with a liver enzyme-the enzyme that makes sugar. It also interferes with the liver’s ability to make fat. Both of those things contribute to the weight loss action of green coffee bean extract.

Another small study showed promising results for green coffee bean extract. When a green coffee bean extract, Stevol,  was added to regular coffee, participants tended to lose weight.

Regular coffee does contain some clorogenic acid, but not nearly as much as green coffee bean extract. Dr. Oz recommends that people should look for green coffee bean extract with at least 45 percent chlorogenic acid. He recommends taking 400 milligrams, 30 minutes before each meal. He says to avoid any coffee bean extract product that does not list ingredients.

Dr. Oz noted, however, that widespread studies on green coffee bean extract are still needed. There is still not any research on its effect on children, for example. Also, participants in the studies have all been in good health, so there is no information on the safety of this product in people with heart, liver, or kidney disease.

The side effects of green coffee bean extract are similar to those of regular coffee. It  can have a stimulant effect, increasing alertness and energy, but it can also cause rapid heartbeat, sweating, and insomnia. Those who have been advised not to drink caffeine containing drinks should also steer clear of green coffee bean extract products that contain caffeine. Not all of them do, which is why it is important to read the labels before you buy the product. Before starting any diet or exercise program, consult with your physician.
