You may have heard of green coffee beans from Dr. Oz's recent television story. It is amazing how a material we've always known about is suddenly discovered as an incredibly potent agent for fat burning. What is a green coffee bean extract?
A green coffee bean extract is an extract of unroasted, green coffee beans. simply put, Green Coffee Beans are Coffee Beans that are fresh and have not been roasted. Green coffee extract has been used as a weight-loss supplement and as an ingredient in other weight-loss products.
 The coffee you usually see is brown because the beans are roasted at a tempetaure of 475 degrees. However, coffee beans are naturally green, and hold more nutrients in them before the roasting process.
In 2011, a study found out that green coffee beans contain a compound called Chlorogenic Acid, which is an active weight loss compound found in pure green coffee beans. This compound is destroyed in the high temperature process of roasting the beans. Researchers believe that this compound keeps down the levels of glucose absorption, thereby aiding the body's fat-burning rate.
 The study tested the efficacy of green coffee bean extract on 16 overweight young adults. These participants were divided into a placebo group and a group that was consuming the extract. Thought the study did not involve many participants, the researchers were surprised to see that the participants in the extract group lost an average of 17 pounds in 5 months, without making other changes to their diet or exercise regiment. What's even more interesting is that these participants saw, on average, a 16% decrease in their total body fat.
The average calorie intake for these participants was 2,400 calories. The average they burnt through exercise? 400 calories. Even with the other needs of the body thoughout the day, that is not enough to explain the drop in weight.
Since then, ABC News, CBS News, and Science Daily News have all covered research stories about the success of green coffee beans in boosting the body's fat-burning rate. Another recent study published on WebMD conducted a similar study with a new group of overweight adults, again attributing its success to Chlorogenic Acid.
What green coffee bean extract should be used?
 Since Dr. Oz did a study on green coffee beans on television, a few extracts have made the claim to be green coffee bean extract. My #1 recommended product, that has all these conditions, is Pure Green Coffee Bean. To release the full benefits of this material, one must make sure that: 1. The green coffee bean extract is 100% pure
Make sure that the label says pure. That means no additional ingredients were added, not even the smallest amount. No fillers, no binders, no taste or color agents were added. There should only be one ingredient in the ingredient list - green coffee bean extract.
(Ingredients you can safely ignore if added at the bottom of the label: Gelatin, calcium carbonate, and magnesium stearate.)
2. It contains a Chlorogenic Acid level of at least 40-50%
Chlorogenic acid is the main fat-burning compound in the extract. Green coffee beans are the most potent plant source of chlorogenic acid. A level of 40-50%, then, is a must to get potent effects.
3. Is at least 400mg per capsule
Make sure that the capsules you are getting are at least 400-800mg. Smaller amounts might be destroyed by the digestion process, and lose their potency.
Where to get it?
In a previous post about Green coffee bean extract, I was asked where one could find it. Well, it can be found at a number of health shops. However, remember to make sure this is the pure extract, and not something else. If you don't know of a shop near you that carries the extract, my #1 recommendation is Pure Green Coffee Bean.
