Ground green coffee beans, taken daily, seem to spur steady weight loss, according to new research. 
In a small, 22-week study, researchers found that 16 overweight men and women lost an average of 17 pounds. They took the green (unroasted) coffee beans in supplement form and, for comparison, took a placebo at a different point of the study.
They did not change their diet. They were physically active. They lost more while on the supplements than while on placebo. They lost the most when on the higher of two coffee bean doses.
“We don’t think it’s the caffeine in it,” says Joe Vinson, PhD, professor of chemistry at the University of Scranton.
He presented the findings Tuesday at the annual meeting of the American Chemical Society in San Diego. The results echo those of earlier studies, but Vinson used a larger dose of the green coffee beans.
The study included people 22 to 46 years old. It was funded by Applied Food Sciences, which makes the green coffee antioxidant supplement.
The results are interesting, but the study was small and short, so further study is needed, says Connie Diekman, RD, director of university nutrition at Washington University in St. Louis.
Will ground coffee beans promise a magical weight loss?
When roasted at 475 degrees, coffee beans are sometimes described as rich and full-bodied. But for the full-bodied person who is not so rich, unroasted coffee beans — green as the day they were picked — may hold the key to cheap and effective weight loss. For that reason, it shows a potential weight loss from green coffee beans.
Our advice is make choice of homemade roasted green coffee beans as the one huge advantage home roasted coffee beans has is that you know they’re fresh roasted. While with commercial coffee, we’re stuck with whatever the coffee roaster deems best. Which very often is the best, but still, who knows?!
