diet. This was followed by six months of an 1800 calorie diet, fewer calories than provided by the famine diet experienced by the civilian population in wartime Europe. The research documented the men's ability to maintain physical output and the psychological effects such as introversion, lethargy, irritability, and severe depression. The study then studied the men's recovery as they returned to a normal diet and regained the weight lost during the experimentation. The men indicated later they would not have volunteered for this project had they known how rigorous it would be. The OSRD was discontinued in December 1947.
