This is an account of an experiment run on consenting conscientious objectors after World War II, with the purpose of finding out what was the best way to help the millions of people who had been deprived of adequate food during the war. The article compares the deprivation that the subjects underwent to that mandated by weight-loss diets. If I hadn't eschewed dieting forever already, this would certainly have made me do so.
