The question that most people ask about hoodia (does it really work) is difficult to answer. Unlike laboratory animals, human beings do not eat only because they are hungry. An appetite suppressant whether a product with hoodia, 100% real hoodia gordonii or a product with any other ingredients will only do one thing; suppress physical hunger. The symptoms of physical hunger are growling stomach, moodiness and shakiness from low blood sugar levels, just to name a few. How many times have you eaten a meal or a snack when none of these symptoms were present?
