Green coffee bean extract

I'm using it. I also take a Saffron pill that contains Satiereal Saffron extract. I've been taking the green coffee for about 3 weeks and I'm staring my 2nd week on the Saffron. I believe I've lost 1# so far BUT I do notice a difference in my appetite. I believe the reasons I haven't lost as much as I could is 1. I do not have to be hungry to eat. So even though I'm not hungry, I find myself eating out of boredom, stress etc...( but I'm doing better with that) and 2. I'm not exercising.
I started these pills because a friend of mine saw it on Dr. Oz so she bought them. The company accidentally sent her 2 bottles of the green coffee so she gave one to me. She has lost about 8#'s so far and has been on them for about 3 weeks as well. She is also exercising for about 30min 3x a week but it's not very strenuous considering she's had a double knee replacement and walks with a cane. I wasn't expecting a miracle with these pills but I can say that they are definitely reducing my appetite and I'm not craving chocolate.
