Forget the acai berry. Green coffee beans could be the newest
weight-loss fad as research has found that the bean extract may help people lose
The bean, which is sold as a supplement in the U.S., has been
deemed an effective weight-loss food by author Joe Vinson who is a
chemist at the University of Scranton in Pennsylvania.
He said: ‘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.’
Keen beans: Green coffee bean extract has been found to be an effective weight-loss supplement. But it has already drew skeptics
Mr Vinson’s researchers give 1,050 milligrams of green
coffee bean extract to 16 obese adults in the 20s. They kept a close eye on the
participants diets, heart rates, exercise regimes, weight and blood pressure
over 22 weeks.
The human guinea pigs shed an average of 17 pounds each. It
worked out to be about 10.5per cent of the group’s overall body weight.
Although the author admitted he is not certain as to why the
particular bean works, he thinks the chlorogenic acid found in green coffee
beans may play a key part.
Due to such mystery, doctors have urged people to tread
carefully with the new weight-loss approach.
Dr David Katz, a director of Yale University’s Prevention Research
Center in New Haven, Connecticut, said it is too early to be recommending
the green coffee beans to people looking to lose weight.
‘The effects, if real, are likely to be
modest and we don’t know if they last over time,’ he said. ‘It’s a supplement,
not a substitute. The emphasis will always need to be on overall diet and
Skeptics have further questioned the bean’s obvious caffeine
inclusion. To some, the well-known stimulant seems like the not-so secret ingredient.
Keith Ayoob, a dietician and associate professor at the Albert
Einstein College of Medicine in New York, is one of them.
‘I’d be happier if the research included pure caffeine, in
the same amount as is contained in the doses of [green coffee bean extract],’
he said. ‘Then you’d know if the effects are due solely to caffeine or to
something else in the beans, or to some combination thereof.’
