Coffee Bean Extract Linked to Weight Loss

iStockphoto/Thinkstock(SAN DIEGO) -- Unlike magic beans that make you grow, green coffee beans may make you lose weight -- and fast.

A new study suggests taking green coffee bean extract, which is sold as a supplement in the United States, could be a safe and effective way to drop some pounds.

“Based on our results, taking multiple capsules of green coffee extract a day -- while eating a low-fat, healthful diet and exercising regularly -- appears to be a safe, effective, inexpensive way to lose weight,” study author Joe Vinson, a chemist at the University of Scranton in Pennsylvania, said in a statement.

Researchers gave up to 1,050 milligrams of green coffee bean extract to 16 overweight adults in their 20s and monitored their diet, exercise regimen, weight, heart rate and blood pressure for 22 weeks. Without changing their diet or exercise, study subjects lost roughly 10.5 percent -- an average of 17 pounds -- in overall body weight. No harmful side effects were noted, according to the study presented Tuesday at the American Chemical Society national meeting in San Diego.

How green coffee bean extract contributes to weight loss is unclear. But Vinson theorizes a chemical in the unroasted bean called chlorogenic acid could be responsible. Other experts suspect the stimulant properties of caffeine could be the culprit.

“I’d be happier if the research included pure caffeine, in the same amount as is contained in the two doses of [green coffee bean extract],” said Keith Ayoob, a registered dietitian and associate professor at the Albert Einstein College of Medicine in New York. “Then you’d know if the effects are due solely to caffeine or to something else in the beans, or to some combination thereof.”

Although green coffee bean extract may be of some benefit for people seeking weight loss, experts say the small study should be interpreted with caution.

“It’s premature to recommend this approach,” said Dr. David  Katz, director of Yale University’s Prevention Research Center. “The effects, if real, are likely to be modest and we don’t know if they last over time.”

“It’s a supplement, not a substitute,” Katz added. “The emphasis will always need to be on overall diet and physical activity.”

Study: Kudzu Extract Decreases Binge Drinking

Photo Courtesy - Getty Images(NEW YORK) -- The extract of the kudzu root was already known to be helpful in treating alcohol abuse, but now a study in the journal Alcoholism: Clinical and Experimental Research suggests it can be used to decrease binge drinking.  

Twelve men were given either kudzu extract or a placebo for nine days, then they were given a set amount of alcohol to drink. Those who had taken the kudzu extract had increased heart rate, elevated blood alcohol levels, and reported greater levels of dizziness compared to those who had taken the placebo.  

The authors don't know why the kudzu caused blood alcohol levels to rise, but they think they've found out why people drink less after taking kudzu. They may feel the effects of the alcohol more quickly. In other words, getting drunk faster may actually reduce how much you end up drinking-- a conclusion even the authors admit is " counter-intuitive."

Still, they say kudzu extract could help manage binge drinking, which could  promote complete alcohol withdrawal along with other treatments.
