Irisis was named for its ability to carry messages between body cells,
after Greek mythology’s Iris, messenger of Olympian gods.
A study conducted by scientists at Harvard has isolated the protein, named irisis, produced naturally during exercise that helps increase calorie burn. Irisis turns white fat into brown, a more metabolically active fat that helps keep us warm. In short, the hormone increases calorie burn beyond that which we get from exercise alone. While studies are expected to head in the direction of approving irisis for pharmaceutical use, “repeated bouts of prolonged exercise” promote a natural increase in the body’s levels. Summary? Hit the gym 4-6 times per week and aim for 30-60 minutes per session.
