Last September (2007) a gallstone showed up on my ultrasound. I changed my diet to lose weight and combat borderline diabetes - started eating a lot more fat, coconut oil especially. I got horrendous headaches and couldn't figure out why. Someone pointed out that chlorgenic acid in green coffee will "kick your liver and gallbladder into gear" to deal with fats. They were right! This is a wonderful thing if you're coming off low-fat or vegetarian/vegan diet.
Well, I have hesitated a lot to give 5 stars to this product but finally i did because: it it realy effiscient. I have lost 1,1 kg in 4 days without changing absolutely nothing! I was only taking 1 pill 30 minutes before diner. BUT I had to stop it for a while reason is: I had strong headache and awful stomach pain. I was not able to work properly so then I went on line and discover a lot of reviews reporting the exact side effects!!! when I stopped I immediatly start to feel better again. I have restart to take it again by reducing the amount taking: a half pill, and so far it's good: my stomach is a bit crampy but it is ok, it's also less effiscient I've only lost 500g in 7 days but it is also OK for me. I'm a person very sensitive to caffeine so that's the main explanation so for those who are interested and that are also sensitive to caffeine, make sure to take a very small amount (half pill) and increase the level slowly.
