What is Green Coffee Bean Extract?
The fruits of a coffee plant are known as berries. They contain green seeds or beans, from which green coffee bean extract is derived from.
Green Coffee Bean Extract & Weight Loss
Both human and animal studies have demonstrated the efficacy of green coffee bean extract in weight loss.
In a study reported in January 2012, 16 subjects took a high dose (1050 mg) green coffee bean extract for 6 weeks, a low dose (700 mg) of green coffee bean extract for 6 weeks and a placebo for 6 weeks, with a 2-week washout period between phases.
All subjects experienced reductions in body weight, body fat and BMI during the high dose and low dose phases, but not the placebo phase.
At the end of the 22 weeks,
- average body weight lost is 17.6 lbs
- average body fat lost is 4.44%
- average reduction in BMI is 2.92
These results were achieved with no significant changes in diet and physical activity!
In two previous studies on the efficacy of a commercial green coffee bean extract, the average weight loss was 5.4 kg in one treated group and 5 kg in another treated group.
How Does Green Coffee Bean Extract Help You Lose Weight?
The weight loss benefit of green coffee bean extract could be attributable to chlorogenic acids and other polyphenols. These compounds may:
- inhibit absorption of fats from the intestine
- enhance fat metabolism in the liver
- inhibit enzyme alpha-glucosidase, thereby reducing glucose absorption
- inhibit enzyme glucose-6-phosphatase, thereby suppressing release of stored blood sugar and formation of new sugar
- inhibit enzyme amylase, thereby reducing carbohydrate absorption
As a result, green coffee bean extract helps to lower calorie intake and reduce body fat accumulation, which eventually leads to weight loss.
Why Not Just Drink Coffee?
Unroasted green coffee beans are a rich source of polyphenols, especially chlorogenic acids. While roasting releases the aroma and flavour of coffee, the process itself destroys most of chlorogenic acids and other polyphenols in green coffee beans.
Research showed that phenolic compounds in green coffee bean extract were highly absorbable and readily metabolised in humans. This is why green coffee bean extract with its low caffeine content, is more beneficial than brewed, roasted coffee.
