Pure green coffee bean extract comes from the green coffee beans that have not been roasted like ordinary coffee. Many of us have heard about it from either Oprah or Dr. Oz on their talk shows, but why has green coffee created such a hype all of a sudden?
In western culture and most other cultures, coffee has always been consumed in roasted form for flavor and caffeine. However, there are other cultures around the world who have been consuming coffee beans without roasting them.
A study was conducted and presented at the American Chemical Society (and published here by National Library of Medine) to determine whether green coffee held any positive properties for efficient and healthy weight reduction in overweight participants.
There were 16 subjects between the ages of 22 and 46 years old who were clinically determined to be overweight or obese. The study was conducted for 22 weeks in the form of a randomized, double-blind experiment.
Subjects received either a placebo, a 700 mg GCA (low dose), or 1050 mg (high dose) capsule randomly for six-week periods with two-week off periods. The subjects were to incorporate the intake with no change in their diet.
Results showed that a body fat percentage of −4.44% ± 2.00% was lost in subjects during the time the GCA was taken.
These results were congruent with previous experimentation in animals, and thus substantiates the claim that pure green coffee bean extract is an efficient and healthy weight loss supplement.
Weight loss due to green coffee appears to be equally effective for both men and women as the 16 subjects were comprised of 8 women and 8 men.
Even though these subjects neither consumed a diet nor utilized any significant exercise routine during the study, there was a −8.04 ± 2.31 kg reduction in body weight, and consequently, their heart rate lowered to healthier levels of −2.56 ± 2.85 beats per minute.
As with any weight loss regimen, a healthy diet and appropriate amount of exercise should be integrated, but the use of green coffee extract will evidently increase the efficacy of fat reduction.
