Starvation, exercise and injury place a metabolic ‘stress’ on the system. This article describes how the body adapts metabolically to a decreased nutrient supply, increased energy demands and a surfeit of nutrient supply. Many patients are malnourished, have impaired exercise tolerance, become injured, or are obese. An understanding of the metabolic physiology of these conditions is therefore desirable.
