Field training in extreme environments presents special performance nutrition requirements. For one thing, in heat and cold and at high altitudes you burn more energy than you do in a temperate climate. Therefore, eat more in extreme environments to fuel your increased energy needs.
Extreme environments create other risks that performance nutrition can help you overcome.
