Very simply put, Green Coffee Beans are Coffee Beans that are fresh and have not been roasted – the coffee we brew has been roasted and this is why it is brown, rather than green. Green Coffee Beans naturally contain a compound called Chlorogenic Acid, which is the active weight loss compound in Pure Green Coffee Beans. Roasting Coffee Beans destroys the Chlorogenic Acid. Recent clinical studies and trials have shown that the specific combination of Chlorogenic Acid and caffeine are effective for weight loss. One particular study followed 16 people (with a body mass index between 25% and 30%) and between 22 to 46 years old. Study participants were monitored for 22 weeks and participants' diets and exercise were strictly monitored throughout the study. The participants ate on average 2,400 calories a day and had a calorie expenditure of 400 calories, nowhere near the levels necessary for weight loss.
