The Way of the Iceman: How the Wim Hof Method Creates Radiant Long-term Health—Using the Science and Secrets of Breath Control, Cold-Training and Commitment

by Wim Hof

There are two varieties of fat: White fat Brown fat White fat mainly stores energy and is a reserve of nutrients. Beneath the skin, it serves as insulation for your body. It protects your organs, and also ensures that they stay in place. The main function of brown fat is warming up your body by burning fatty acids and glucose. One consequence of Hof’s many years of training is that he has a lot of brown fat. Brown fat releases energy directly, generating heat. Newborn babies have a lot of brown fat, so that they can warm up quickly in a cold environment. After nine months, there is little left of this brown fat. Each year, it decreases, perhaps because of clothes and blankets. Adults in Western societies have almost no brown fat left.
