Do Green Coffee Beans Work

Do Green Coffee Beans Really Work?

One of the most popular and talked-about weight loss supplements of recent years is extract of green coffee beans. The green coffee bean has been featured on the Dr. Oz show, and has been studied scientifically since the craze began in late 2012. The green coffee beans are the same bean as the ones used to make coffee, except that the green coffee beans have not yet been roasted.

Studies Have Shown They Work

The Dr. Oz show did perform an independent study of the green coffee bean extract, which studied 100 female volunteer viewers. The volunteer test subjects were instructed not to change their diets or exercise regimes throughout the study. The results showed that over a two week period, the volunteers that were taking the green coffee beans actually lost an average of two pounds compared to the average one pound loss of those volunteers that received a placebo. The volunteers taking green coffee bean extract were given 400 milligrams daily for two weeks.

Another well=known study seems to support the efficacy of green coffee beans for weight loss. At the 2012 American Chemical Society (ACS) National Meeting & Exposition, Dr. Joe Vinson of the University of Scranton in Pennsylvania presented his findings from a 22 week-long study. Dr. Vinson and colleagues studied 16 medically overweight or obese subjects between the ages of 22 and 26. In this study, volunteers were given a dose of either 700 mg or 1,050 mg in rotations. Test subjects did not make any other changes to their routines while participating in the study. The results were an average weight loss of 17 pounds. This was a 10.5 percent total body weight decrease and 16 percent body fat decrease. When the findings were presented, Dr. Joe Vinson stated that combined with other healthy choices, taking green coffee bean supplements “appears to be a safe, effective, inexpensive way to lose weight,”

What Causes the Weight Loss?

The green coffee beans contain chlorogenic acid, which is known to make it harder for your body to absorb fat from the food you eat, and also has an increasing effect on metabolism so that fat is more quickly metabolized. This also explains why regular beverage coffee doesn’t have the same effect, because chlorogenic acid begins to break down at 464-482 degrees Fahrenheit. Therefore, the active weight loss ingredient is cooked out when coffee beans are roasted.
