An extract of unroasted coffee beans used in weight supplements, the so-called green coffee bean extract, does probably not help in the loss of weight, according to a new study published in the Journal of Agriculture and Food Chemistry.
Chlorogenic acid (CGA), one coffee polyphenol, is the main ingredient in such weight-loss supplements, which researchers fed to mice, measuring its effects. One group of mice was fed the supplement with a high-fat diet, while another group was fed a high-fat diet with no supplement.
According to the study, the supplement showed no benefits and was, in fact, associated with an unhealthy build-up of fat in the liver.
"This study suggests that higher doses of CGA supplementation in a high-fat diet does not protect against features of the metabolic syndrome in diet-induced obese mice," the research team wrote in its conclusions.
