The ingredients in my Chocolate banana pills are as follows: Cha de Bugre which is basically a diuretic but is also renowned for its ability to speed up your metabolism which is a key part in loosing weight. They have 190mg of caffeine, hence the figeting, but which is also a diuretic so a lot of the weight you lose is water from your body so make sure you are consuming plenty of liquids because you know what they say, when you don't feel thirsty anymore, you're already dehydrated which is bad!!! 3L a day people, on these pills. Then there is the 'Naringun' which I believe to be a misspelling, I believe it SHOULD be naringin which is an extract of Grapefruit and helps in fat burning. So there you have it. What I'm not sure about is the pills ability to stop you feeling hungry or even THINKING about eating, it's pure ability to actually make you want to NOT eat... I think that may be due to the CHa de Bugre which is also referred to as the 'Brazilian Diet pill'. Look it up
