New research has demonstrated that unroasted coffee beans, or “green coffee bean extract” may help with weight loss possibly because of its effect on glucose and fat metabolism. In a small clinical trial, 16 overweight individuals taking different doses of green coffee bean extract lost an average of 17.5 pounds and 16% in body fat, in 22 weeks.

Green coffee beans are coffee beans, which have not been roasted. And green coffee bean extract is an extract from the unroasted green coffee bean.

In March of 2012, Dr. Joe Vinson performed a clinical study with this substance and found a significant connection between consumption of green coffee and fat loss. Vinson speculates that this may be due to chlorogenic acid, which Vinson believes reduces the absorption of glucose and lowers the hyperglycemic peak. Vinson is a chemist at the University of Scranton in Scranton, PA. He says his successful trial results should pave the way for more research on this substance. So, a larger trial is being planned. Dr. Vinson adds that green coffee bean extract may also reduce insulin levels, which would improve metabolism function. He also said there were no indications of negative side effects reported by any of the clinical study participants.
