Welcome to another episode of the Understanding Disordered Eating podcast. In this episode, we will be diving deeper into the Minnesota Starvation Experiment or the Minnesota Semi Starvation Experiment. This study was conducted by Ancel Keys, who was a professor of Physiology at the University of Minnesota. During World War II, he was a consultant to the War Department, and wanted to study the effects of starvation most significantly for those who were in the war, and how to provide post-war rehabilitation.

Though this study is being cited all the time, it is important to note that it only had a total of 32 participants. And while it has a very small sample size, the information that we learn from the study is still significant and important.

“By learning about the effects of starvation, we can avoid attributing all of these symptoms to some other causes that aren't connected to just a significant calorie deficit.” - Rachelle Heinemann
