The Minnesota Starvation Experiment refers to a landmark study conducted during World War II at the University of Minnesota. The experiment aimed to investigate the physiological and psychological effects of severe human starvation.
The study involved 36 mentally and physically healthy young men who voluntarily participated. The subjects were subjected to semi-starvation, which involved reducing their calorie intake to approximately half of their normal level. The goal was to replicate the conditions experienced by European populations hit by famine during the war.
Throughout the experiment, the subjects' physical and psychological responses to starvation were meticulously recorded. Researchers observed a range of physiological changes, including significant weight loss, reduced metabolic rate, slowed heart rate, and anemia. Psychologically, the participants exhibited disturbed thoughts and behaviors associated with preoccupation and obsession with food, apathy, mood swings, and reduced concentration.
The Minnesota Starvation Experiment greatly contributed to our understanding of the long-term effects of severe malnutrition on both the body and mind. It shed light on the process of weight loss and the adaptations individuals undergo during periods of famine, highlighting the importance of proper nutritional support in these situations. The study also had relevant implications regarding the treatment of individuals suffering from anorexia nervosa, as it provided further insights into the psychological aspects of starvation.
Overall, the Minnesota Starvation Experiment remains a pivotal research project for comprehending the effects of starvation on the human body and mind, serving as a foundation for subsequent studies in the field of nutrition and psychology.
