Green coffee extract, a miracle to lose weight?

Recently it has been published in the journal Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy a study in which spectacular results of weight loss have been achieved by supplying green coffee extract to obese people. The research involved 16 obese subjects ( here is the full report ) and they were made to take different doses of the extract (in higher amounts than in other studies, close to one gram) and a placebo, without there being significant variations in feeding. After 22 weeks, weight losses of about eight kilos were reached and 6 of the 16 participants went from being obese to having a normal weight. 

Experts think that chlorogenic acidYou could be responsible for this beneficial effect.Although the sample is very small and more studies are needed, the results are promising, especially since the product is very economical. We will have to pay attention to future investigations. 

Update : 

As often happens in these cases, these results have not been confirmed by other studies. A systematic review  found no strong evidence on the subject and EFSA either .
