In the waning days of World War II, a group of 36 healthy American men volunteered for an extraordinary scientific experiment that would forever change how the world understands starvation.
The study, led by physiologist Ancel Keys and psychologist Josef Brožek at the University of Minnesota, subjected participants to six months of semi-starvation to simulate the famine conditions millions faced in war-torn Europe.
Writing in the Financial Times, science columnist Anjana Ahuja revisits this harrowing experiment, describing how it laid the foundation for the modern science of human starvation and how its lessons are urgently relevant in today’s hunger-stricken conflict zones.
The Minnesota Starvation Experiment, as it came to be known, meticulously documented how bodies and minds unravel under prolonged food deprivation.
The volunteers, who began the trial in peak physical condition, soon became shadows of themselves, losing a quarter of their body weight on average and nearly half their muscle mass. But the psychological toll was equally disturbing: intense food obsession, depression, anxiety, emotional numbness, and social withdrawal.
When refeeding began, it brought another layer of complexity. Many participants experienced extreme hunger that persisted even after their caloric intake was restored. Some ate uncontrollably, while others experienced nausea and pain.
The experiment revealed the danger of refeeding syndrome—a deadly metabolic disturbance caused by a sudden influx of nutrients in a body weakened by prolonged starvation.
The findings, published in 1950 in the two-volume Biology of Human Starvation, remain a cornerstone in fields ranging from nutrition science to eating disorder treatment and humanitarian aid.
“Keys and Brožek showed how hunger reshapes not only the body but the mind,” Ahuja notes, emphasising that starvation is not merely a medical condition, but a profound psychological and social crisis.
Their work also carried a bold political message: hunger destroys not just individual health, but societal cohesion. Keys argued that democratic rebuilding would be impossible in countries where basic nutrition was out of reach. That insight feels painfully relevant today.
Ahuja draws attention to current crises such as in Gaza, where aid agencies warn that widespread malnutrition, disease, and death from hunger may be unfolding in real time.
The Minnesota study is a sobering reminder that starvation is rarely just about food. It’s about systems, survival, and the human psyche.
As the world continues to grapple with famine in conflict zones, climate-affected regions, and refugee camps, Ahuja’s revisitation of this historic experiment reminds us that scientific knowledge alone is not enough. What is needed—then and now—is political will and humanitarian urgency.
