During World War Two, conscientious objectors in the US and the UK were asked to volunteer for medical research. In one project in the US, young men were starved for six months to help experts decide how to treat victims of mass starvation in Europe…The experiment started in November 1944 and for the first three months they were fed to their optimum weight and monitored. Then their rations were cut dramatically. Food quickly became an obsession.
