Minnesota Starvation Study

Many people know what is allowed in experiments nowadays is much more restrictive than in the past. Experiments like Stanford's prison experiment would not pass muster at a university human subjects approval board. I recently stumbled upon another experiment that could not be repeated: the Minnesota Starvation Study was a military-endorsed study at the University of Minnesota in the 1940s to examine the psychology and, to some extent, the physical changes men undergo when starving. (Starvation meant cutting each participant's diet to half his usual number of calories for six months.) The reports lend themselves to slightly disturbing but quite interesting reading.

The experiment isn't discussed much on anything web accessible -it's too old-, but I did manage to find three good pieces:
* Minnesota Goes to War: The Home Front During World War II A book, pages 210-216 cover the Minnesota experiment. You probably won't be able to read all of those pages online.
* They Starved So That Others Be Better Fed (Journal of Nutrition). The first result on that link should be the article. Sadly, the images from the original article don't appear on the web page.
* Effects of Semi-Starvation (adaptation of chapter from Handbook for Treatment of Eating Disorders).
