Food may not always be readily available, and when the human body fails to consume any food for more than a day or two, the body enters the process of starvation. The process of starvation is actually a series of different defense mechanisms at the disposal of the human body that have been crafted over the millions of years of our evolution; crafted so finely that the body can survive up to around seventy days without any food. Before delving into the effects of starvation, it is important to understand a general overview of how the human body uses the food it consumes. The three main nutrients in food are proteins, fats, and carbohydrates. Proteins are converted into amino acids that are used to construct new proteins. Fats are used as an immediate source of energy, and unused fats are packaged into triglycerides and stored in fat cells for use when energy becomes scarce. Carbohydrates are the main source of the body’s energy which are converted to glucose for immediate use and some glucose is stored as the polysaccharide glycogen for later use. Together, glucose, proteins, and fatty acids compose nearly all of the body’s energy needs when on a normal diet (Gebel, 2011).
