If you are a fan of the Dr. Oz show, then you may have heard about green coffee bean extract. If you have not, Dr. Mehmet Oz introduced green coffee bean extract as a supplement that can aid in a person’s weight loss journey. This article will tell you about the benefits of green coffee bean extract, introduce you to some of the studies that have proven its efficacy, and also alert you to possible minor side effects and the ways to deal with them.

Green Coffee Beans
Green coffee beans are coffee beans that are unroasted. Although green is the natural color of coffee beans, they are roasted long before they get to stores. It is through the roasting process that these beans become brown.

Green coffee beans are a known source of antioxidants. Antioxidants block free radicals from doing damage to your body’s cells. They also contain active pharmacological compounds such as chlorogenic acid. Chlorogenic acid is the active ingredient in green coffee beans as they are the substance that directly influences weight loss. Most, if not all, of the effects of chlorogenic acid are depleted once the coffee beans are roasted. This is why drinking coffee is not known to help people lose weight.

How Green Coffee Bean Extract Helps You Lose Weight
Green coffee bean extract contains caffeine, which has been known to boost a person’s metabolism from 3 to 11 percent. Despite this finding, scientists still believe that most of the effects of green coffee bean extract come from chlorogenic acid. According to a few studies, chlorogenic acid could reduce the amount of carbohydrates that is absorbed into a person’s digestive tract. This process lowers incidents of insulin and blood sugar spikes. The results of these studies show that taking a green coffee bean extract supplement could be similar to eating a low-carb diet.

There were other studies performed on mice and rats that showed that green coffee bean extract can help a person shed pounds, reduce fat that a person absorbs in their diet, lower the amount that is stored in the liver, and boost the performance of fat burning hormones. In the same studies, chlorogenic acid was shown to improve the levels of cholesterol and triglycerides in the rat subjects. These findings are important as both cholesterol and triglyceride levels are essential components of determining a person’s risk for heart disease.

Green Coffee Bean Extract Studies Done on Human Subjects
One study involved two groups of 30 overweight people. For a period of two weeks, one group consumed instant coffee while the other drank instant coffee that was enhanced with green coffee bean extract. Both groups were instructed to make no changes to their diet during the study. The group that drank the instant coffee that was mixed with green coffee bean extract lost almost 12 pounds, while the other group only lost 3.7 pounds. The green coffee bean extract group also lost 3.6 percent of total body fat, while the other group lost only 0.7 percent.

The Other Health Benefits of Green Coffee Bean Extract
Green coffee beans not only affects how our bodies use carbohydrates, they also help our bodies reduce its levels of glucose absorption. This not only has a positive affect on a person’s weight, it also helps a person manage their risk of getting diabetes.

Green coffee bean extract can also have an affect on a person’s blood vessels. Studies have shown that daily doses between 140-720 mg can reduce blood pressure in both people and rats.

Green coffee bean extract contains caffeine, so you will want to be careful with it if you are sensitive to its effects. This extract is not safe for women who are pregnant or breastfeeding. Children should also avoid this type of supplement.
