A lot of people talk about different types of fat loss aids being metabolism boosters without really having a clear understanding what their metabolism actually is. Your metabolism is basically the rate at which food is digested, absorbed, and used by the body. By increasing your metabolism, you can burn more fat as energy. Keep in mind that this doesn't require the stimulant heavy products that a lot of people view as 'fat burners'. Just because a product gives you a lot of energy or suppresses your appetite does NOT mean it increases metabolism. Sure, a higher activity level and eating less are helpful for weight loss, but the higher your metabolism is, the better a higher activity level and healthier diet can help you.
Thryocaps can help by two different mechanisms, but helping to optimize thyroid function and by helping uncouple proteins. Uncoupling proteins helps to break down and burn fatty acids (fat) to be used as energy.
