In a small, 22-week study, researchers found that 16 overweight men and women lost an average of 17 pounds. They took the green (unroasted) coffee beans in supplement form and, for comparison, took a placebo at a different point of the study.
0.7 grams and 1,05 grams of green grounds per participant per day in the study when on the real deal.
So, it seems they ground up the beans and let the volunteers have them as a pill with water (very bitter, they warn, hehe).
My question is if any of you ever tried grinding green beans on your grinder and is there any reason why this might damage an otherwise great grinder?
