One of the recent newcomers to weight loss science is green coffee bean extract, or GCBE. Weight loss proponents of GCBE claim it helps with increased metabolism, balanced glucose (blood sugar levels) to reduce cravings, and prevents the body from storing unnecessary fat. The first conclusive test on the effectiveness of the extract for weight loss purposes was conducted in January 2012 for dosage levels at 700 and 1050 milligrams with the results published in Diabetes, Metabolic Syndrome and Obesity. The findings were staggering. The study showed "significant reductions" in the areas of body weight, body mass index, percentage of body fat, and slightly lowered heart rates.
