VivaSlim formula uses an actual scientific mechanism to address the obesity issue, that is, by helping the body with metabolic rate. There is proven research showing how metabolic rate determines a person's weight, and any changes can significantly affect this process. If there is something that could speed up metabolic rate, there are good reasons it will help the body with weight loss. Some Viva Slim ingredients work to clear the body from toxins, which is another reason the metabolic rate declines. With detoxification, the metabolism comes back to normal; the body gains lean mass and stops gathering fat layers, leading to a leaner and slimmer body. Other ingredients work on suppressing appetite, regulating blood pressure, sugar and protect the heart.
