Take, for instance, the Dr Oz green coffee bean extract recently talked about. The studies he had read including the Diabetes, Metabolic Syndrome and Obesity Journal’s study on the effects of green coffee beans on sixteen adults over the course of 12 weeks, prompted Dr. Oz to start his own experiments with the product. In the Journal’s study, the subjects dropped an average of seventeen pounds, resulting in a 16% reduction of their fat (10% of their overall body weight and 4.4% of their overall body fat). This was done without side effects since the green coffee bean is 100% all-natural.
