Cayenne pepper consumption dilates the blood vessels and speeds the metabolism due to the high amounts of capsaicin. With the consumption of cayenne peppers, the amount of heat the human body puts off is influenced. In animal studies, capsaicin has the ability to boost metabolism, which in turn causes weight loss. This increases circulation and blood flow to all major organs, facilitating oxygen and nutrient delivery
