Working out in the cold

Do you burn more fat if you work out in the cold? The answer is yes. If you work out in the cold you burn about 37% more fat. The exact mechanism for this is not know but it may have something to do with the different types of fat in your body. In your body there is brown fat and white fat. Brown fat is more metabolically active and actually helps you burn more white fat and that is what you want. One of the ways to activate this pathway is by working out in the cold. On Arthur Devany's site he talks about how surfers always stay lean because they are always in the cold water.
