From Revisionist History: The Starvation Experiment
Malcolm Gladwell's Revisionist History explores the 1944 Minnesota Starvation Experiment, where 36 volunteers endured severe calorie restriction to study its physical and psychological effects and inform post-war relief efforts. The episode highlights the extreme human costs and ethical dilemmas of the study, revealing profound insights into starvation's impact.

5 Key Concepts
Minnesota Starvation Experiment
A human challenge trial conducted during World War II at the University of Minnesota, designed to study the physical and psychological effects of starvation and the most effective ways to refeed malnourished individuals. It involved 36 volunteers who underwent a year-long regimen of controlled feeding and severe calorie restriction.
K-ration
A high-calorie, pre-prepared meal developed by Ansel Keys for the US Army before and during the Second World War. It was designed to be a streamlined, balanced, and vitamin-rich meal for soldiers, particularly paratroops, tank busters, commandos, and isolated units.
Ethical Guidelines in Medical Research
The historical shift in human experimentation from prioritizing the value of scientific learning over subject well-being (as seen in past studies like Tuskegee and Milgram) to the modern standard where the subject's well-being is the number one consideration, involving regulations, consent forms, and the right to withdraw.
Starvation vs. Hunger
A distinction made by subjects of the experiment, where normal hunger is a temporary desire for food, while true starvation involves deep, physiological cravings that profoundly alter one's body and mind, leading to intense irritability and obsessive thoughts about food.
Souping Meals
A behavior adopted by subjects during the starvation phase, where they would add water to their limited food portions. This was done to create a psychological sense that their meals were larger and more substantial, despite the actual caloric content remaining the same.
5 Questions Answered
The experiment aimed to investigate the physical and psychological effects of starvation and determine the best methods for refeeding people who had been malnourished, to inform relief efforts during and after World War II.
Ansel Keys was a prominent 20th-century American physiologist and nutritionist, known for developing the K-ration for the army and leading the Minnesota Starvation Experiment. He was considered America's first true celebrity doctor.
In the past, the primary consideration was the value of what could be learned from the subject, often treating subjects like soldiers whose well-being was secondary. Today, federal regulations, consent forms, disclosure statements, and the right to drop out prioritize the subject's well-being above all else.
Subjects became increasingly irritable, obsessed with food (collecting cookbooks, watching others eat), dreamt about food, and experienced mood swings, emotional degradation, and even moments of irrational hatred.
No, a human challenge trial like the Minnesota Starvation Experiment would violate numerous ethical guidelines and federal regulations in modern medical research, making it impossible to repeat.
4 Actionable Insights
1. Prioritize Varied Whole Foods
Focus on obtaining vitamins from a wide variety of good food rather than relying solely on vitamin pills. According to Dr. Keyes, the best and natural way to supply vitamins is through diverse food, as pills cannot substitute for actual food when it comes to preventing starvation.
2. Cultivate Self-Possession & Resolve
Develop a strong sense of self-possession and unwavering resolve, as exemplified by Ansel Keys, who was noted for doing what he set his mind to from a young age. This trait can be instrumental in achieving ambitious goals.
3. Increase Perceived Portion Size
To create a psychological sense of larger portions, particularly when calorie-restricted, add water to your meals (a practice called ‘souping’). This technique was used by subjects in the Minnesota Starvation Experiment to make their limited food supply feel more substantial.
4. Utilize Allowed Indulgences for Coping
When facing severe restrictions or deprivation, lean on the few permitted indulgences, such as excessive coffee consumption (12-18 cups a day) or chewing large amounts of bubblegum. These were used by the starvation experiment subjects as coping mechanisms to manage discomfort and cravings.
5 Key Quotes
When I hear somebody say, oh, I'm simply starved, I know they don't know what they're saying. Because there's a real difference between what your body craves for as a result of starvation than what you normally feel as hunger.
Malcolm Gladwell
Human misery and want are qualities of life which properly bring an emotional response, but starvation is quantitative and must be met with quantitative answers.
Ansel Keys
I mean, we would lick the plates.
Earl Heckman
I suddenly hated that boy and that, I hate at this point to tell you this because it doesn't speak very well for me but I remembered it with, I guess, horror that, that I could feel such a thing so utterly irrational but, but there it was and, you ask, an experience that I remember, I sure remember that.

For the rest of my life, people are going to ask me what I did during the war. This experiment is my chance to give an honorable answer to that question.

Minnesota Starvation Experiment Design
Ansel Keys (as described by Malcolm Gladwell)- **Control Period (First 3 months):** Each research subject was stabilized at their estimated correct weight, consuming three full meals a day with intake matching outtake.
- **Severe Calorie Restriction (Next 6 months):** Subjects underwent severe calorie restriction with the goal of losing 25% of their ideal weight. This phase included mandatory exercise (22 miles a week of walking), regular testing (blood, sperm, body fat, blood volumes), and keeping journals. They received just two meals a day, consisting of foods like cabbage, potatoes, bread slices, rutabagas, and occasional macaroni and cheese.
- **Recovery Period (Final 3 months):** Different rehabilitation diets were tested with varying amounts of calories, protein, and vitamins to determine the best way to bring the undernourished back to health.
