But the men’s sufferings were not yet over. As the participants in the Minnesota starvation experiment discovered in 1945, the recovery period was a torturous part of the ordeal. After three months, the Minnesota volunteers still had not returned to their normal weights, even though some were consuming more than five thousand calories a day. They would eat until their stomachs could not take any more, yet they still felt hungry. Many would continue to eat between meals. It wasn’t until after six months of “supernormal eating” that they had regained the bodies they had once possessed.
