Losing weight is one of the common modern-day health concerns. Wouldn't it be great to find a nutroceutical, with few to no side effects, to help in that struggle? There are promising indications that green coffee bean extract may be just what you're looking for!
No less than 18 clinical studies have been done on the effectiveness of green coffee beans for dieters, many of them smaller studies or in-house research. Still, the findings are significant.
One study analyzed the results of 3 randomized clinical trials. They were all conducted upon overweight subjects and measured weight loss as an outcome of taking the supplement. While they noted that the studies were small, they also noted that all three studies showed a consistent correlation between the consumption of green coffee bean extract and moderate but consistent weight loss.
A summary of the outcomes of each the studies they analyzed can be seen here.
Another important piece of research is this 2012 study (Vinson, Burnham, Nagendram) conducted to test the effectiveness and safety of green coffee extract on overweight subjects. The results of this 22-week study showed that subjects taking green coffee bean extract experienced significant reductions in weight, BMI (body mass index) and percentage of body fat compared to the placebo group.

Green coffee bean extract has been tested on subjects who were overweight or pre-obese. If you have a lot of weight to lose, you may also want to consider African Mango - which has been more heavily tested for effectiveness upon obese participants.
The active compound in the bean extract is chlorogenic acid, also known as CGA.
It is believed that CGA may inhibit the absorption of sugar from starches and decrease caloric input. More significantly, it also appears to influence glucose metabolism, which could lead to reductions in body fat and body mass indices. Other studies suggest that chlorogenic acid slows the absorption of fats from the intestine and activates fat metabolism in the liver.
Caffeine has also been linked to weight loss as well as a lowered risk of metabolic syndrome. Although there is not a lot of caffeine in these products, it may contribute to their effectiveness.
Additionally, the polyphenols in coffee enhance metabolism and slows the development of fat cells, which can lower the tendency to accumulate body fat.
