Use of Green Coffee Bean
Research has shown that coffee existed over 1,000 years ago and were commonly used in Africa.
Arabica were popular in South Sudan and Ethiopia while robusta was popular in West Africa.
At that time, beans were not roasted, but were blended with fat and seeds to make the earliest version of energy bars.
The ancient civilizations boiled the leaves to create green coffee bean drink that they used as an added energy boost. Other cultures used green coffee bean herbs to make teas and other substances used for medicinal purposes.
It wasn’t until African slaves brought the beans to Asia in the 1400s that roasting began, creating the liquid today known as coffee.
As a result, the consumption of green coffee beans dropped significantly as people preferred the roasted beans.
Then, in 2012, Dr. Mehmet Oz aired a segment on his popular afternoon television series, “The Dr. Oz Show,” which featured a study that found the use of green coffee bean could improve weight loss results.
Following the show, sales of green coffee beans rose significantly.

What Does Green Coffee Bean Do?
There is extensive research that indicates the benefits of chlorogenic acid on weight loss, blood pressure and how the body regulates blood sugar.
When coffee beans are roasted, they lose much of the chlorogenic acid which is why green coffee beans are a better option.
However, the bitter taste of green coffee beans means they are not suitable for brewing without being roasted.
For this reason, many people choose green coffee bean pills or other supplement versions to get green coffee bean for weight loss benefits.
Chlorogenic acid is also found in prunes and is thought to be the compound that causes the laxative effect, which is also a side effect found in coffee.

In a 2011 report published in Complementary Medicine, a publication of the Peninsula Medical School at the University of Exeter, researchers found that several animal studies that found a change in glucose concentration in rats, indicating that green coffee bean capsules and oils may provide the same benefits in humans. 
In this study, a review of several clinical trials found that there may be a connection between the intake of green coffee bean extract and weight loss, but because the samples in those studies had been small, more research needed to be conducted.
Another report in the Journal of International Medical Research found that coffee enriched with chlorogenic acid appeared to have an effect on the absorption and utilization of glucose.
This indicates that the use of a green coffee bean dietary supplement may result in a reduced body mass and could result in a reduction of body fat when used consistently.
Green Coffee Bean and Gallstones
In addition to weight loss, researchers are finding that the supplements may also reduce the risk of gallstones, adding one more green coffee bean extract benefits.
Bile is produced in the liver which is then emptied into the gallbladder. Inside the gallbladder, bile is either stored temporarily or emptied into the small intestine.
Impairments of the flow of bile in the gallbladder can result in the development of gallstones.
In a study conducted at the Institute for Traditional Medicine in Portland, Oregon, Dr. Subhuti Dharmananda found that increased intake of chlorogenic acid improved the flow of bile and reduced the risk of stagnation in the gallbladder. 
There are those who believe that a green coffee bean detox helps cleanse the liver and gallbladder as well.
Green Coffee Bean and Blood Pressure
Several research studies have found that chlorogenic acid reduces blood pressure in hypertensive rats and humans.
Clinical trials found that substances like a green coffee bean dietary supplement can reduce blood pressure and pulse rate.
In one study, it was determined that green coffee bean diet supplements did reduce blood pressure and had no side effects.
However, the study also found that there was no difference in body mass index or pulse rate.

Green Coffee Bean and Diabetes

In addition, the participants saw a 10 percent reduction in weight.
The study was a small sampling and more research is necessary to determine how green coffee bean extract may benefit those diagnosed with Type 2 diabetes.
Green Coffee Bean and Energy
Green coffee beans have no coffee flavor but contain the same amount of caffeine as roasted beans which is why many people use green coffee bean for energy.
The extraction process used while roasting the beans is what increases the amount of caffeine in the beans.

Both groups were instructed not to change their diet. At the end of 12 weeks, the group drinking green coffee bean coffee lost almost 12 pounds while the group drinking regular coffee lost less than four pounds. 
In addition, the green coffee bean drinkers lowered their body fat by almost four percent while the regular coffee drinkers saw a body fat drop of less than one percent.
