The Minnesota Starvation Experiment

Food Storage Made Fabulous, the 2nd volume of articles from the Prep School Daily blog, is now available on Amazon.  With over 100 family-friendly recipes using basic long-term food storage staples, your family will have no idea there's a crisis. 

Do you know anyone who has ever dieted?  How fun are they to be around?  Have you or has anyone you know ever tried the intermittent fasting diet?  Now that is fun.  You eat normally five days per week, and for the other two days you get 500 calories for women or 600 for men.  I lost weight, but I hated diet days.  And even though I thought I was doing well with it, my family hated diet days because apparently I was cranky.  And that's when we all knew that the diet day would end at bedtime, and that if I really wanted to, I could go eat anyway.  What happens when there really isn't any more food, at least for that day's rations?


I don't know about all of history, but in recent history there have been conscientious objectors to war.  While some probably were just trying to avoid military service altogether, others truly wanted to serve their country but had an insurmountable objection to killing another human being.  Some of these men became ambulance drivers and medics.  A small group of others, men aged 22 to 33 years old, volunteered to participate in the Minnesota Starvation Experiment, conducted between November 1944 and December 1945.  Of the 400 men who volunteered, 100 were selected for personal interviews to identify suitability for the study.  Ultimately, 36 of the best and brightest were chosen--men with college education who exhibited the greatest levels of physical and emotional stability. 

The stated objective of the experiment was to simulate the effects that starvation resulting from the then-current war would have on the people of Europe and thus be able to determine the best ways to help them recover when hostilities ceased.  The volunteers were all healthy young men of military age.  During the first twelve weeks of the study, the men were carefully observed so that baseline psychological and physiological behaviors could be established.  They consumed an average of 3200 calories per day and were required to walk 22 miles per week, just over three miles per day.

The starvation phase lasted 24 weeks.  The men continued walking 22 miles per week, as refugees just might, and were given diets ranging from 1200 to 1800 calories per day.  The goal was to get the men to lose 25% of their original body weight.  They were fed twice per day with foods thought to be common to the starving populations of Europe--potatoes, rutabagas, dark bread, macaroni, and turnips, among other things.  The diet was very high in carbohydrates and low in protein.  And not only is it similar to what starving populations then were eating, it's also pretty similar to what a lot of people store now.

During the starvation phase, the men lost all interest in anything that didn't involve food.  They were hungry all the time.  Even just after they ate, they were still hungry.  They also reported a decrease tolerance to cold and needed extra blankets, even in the summer.  They were dizzy, extremely fatigued, and experienced muscle soreness, hair loss, and reduced coordination.  Some had to quit college because they could not concentrate. Most of the volunteers exhibited serious distress and depression. 

Of the thirty six volunteers who started the experiment, four were unable to finish for various reasons.  Two began stealing food to eat, including raw rutabagas, and were treated for psychiatric issues as well.

During the recovery phase, the goal was to get men back to their original weight.  The men were given varying amounts for their rehabilitative diets, from 400 to 1200 extra calories per day, to re-nourish them.  The volunteers still felt like they were starving. 

After the conclusion of the experiment, when the men could eat whatever they wanted, some were consuming up to 10,000 calories per day.  It was then that they regained their weight, and many gained up to 10% more.

When you store the minimum amounts recommended by members of the Church of Jesus Christ of Latter-day Saints, people who have advocated and studied food storage for over 150 years, you are storing about 2,000 calories per day.  That minimum does not work out well if you are doing heavy labor or are pregnant or even stressed.  Mental stress also demands a lot of calories.  If you've purchased one of those year's storage kits that touts 1,200 calories per day, do you think your family is really going to be happy?  Will you tell yourself that the crisis will end before the food runs out, so you eat it more quickly?

Maybe you should try out living on 1,200 calories a day to see how it goes.  Do it with the whole family.  Remember, those men in the experiment were volunteers and they knew the experiment would come to an end.  When the grid goes down, no one really knows when it will come back up.  How are you going to react when you are hungry.  All. The. Time?  Are you going to be patient with your family members? The men in the experiment became introverted.  They easily lost patience with one another over the most trivial of issues.  It won't be any different for us.

One of the interesting findings of the experiment was that the men needed over 4,000 calories per day to begin rebuilding their bodies, and it took them up to two years to do it. 

Maybe it's time to do a little more shopping and stocking.  There's no time like the present!
