Green coffee beans may help weight loss

Syracuse (CNN) -- Unroasted coffee beans may be the key to a quick weight loss.

A new study found that a small group of overweight people lost about 10-percent of their body weight after eating less than an ounce of ground, green coffee beans every day for 22 weeks.

Study participants combined the coffee with a low-fat diet and exercise.

Researchers suspect a substance found in unroasted coffee beans known as chlorogenic acid may be behind the fat burn.

The study was presented at the American Chemical Society's spring national meeting this week.
