You may have heard of green coffee bean extract-it's been touted for its weight-loss properties recently-but what exactly is it? And can it really help you lose weight?

Green coffee bean extract simply comes from the unroasted seeds (or beans) of the coffea plant, which are then dried, roasted, ground, and brewed to produce coffee products. Mehmet Oz, M.D., of the Dr. Oz Show, decided to find out, so he conducted his own experiment by enlisting 100 women who were overweight or obese. Each woman received either a placebo or a green coffee bean supplement and were instructed to take 400mg capsules three times per day. According to Dr. Oz, the participants were instructed not to change their diet and also to keep a food journal to record everything they ate.

So does green coffee extract work? Yes, says Dr. Oz. After the two weeks, the participants who consumed the green coffee bean extract lost, on average, two pounds, while the group of women who took the placebo lost an average of one pound.

However, this doesn't mean the green coffee bean extract caused the weight loss. It's important to note that compounding variables might have influenced the results. For example, though they were instructed not to change their diet, the women may have been more aware of their diet since they were keeping a food journal.

If you're interested in supplementing your weight-loss efforts with green coffee bean extract, it's important to pick the right kind. The supplement you take should include chlorogenic acid extract, which may be listed as GCA (green coffee antioxidant) or Svetol. Dr. Oz notes on his website that the capsules should include at least 45 percent chlorogenic acid. Any less than that amount hasn't been tested in studies that focus on weight loss. One example of a product that contains green coffee extract is Hydroxycut (pictured below).
