"In a randomized, double-blind, 12-week study we investigated the effect of Green Coffee on the body mass of 30 overweight people, compared with normal instant coffee. The average losses in mass in the Green Coffee and normal instant coffee groups were 5.4 and 1.7 kg, respectively. We conclude that Green Coffee appears to have a significant effect on the absorption and utilization of glucose from the diet."

"The results suggest that Green Coffee may be an effective nutraceutical in reducing weight in preobese adults. Significant reductions were observed in body weight, body mass index and percent body fat, as well as a small decrease in heart rate, but with no significant changes to diet over the course of the study."

"It was found that Green Coffee reduced visceral fat content and body weight. Chlorogenic acid [found in Green Coffee] and its related compounds are found to be involved in the enhancement of fat metabolism in the liver."
