 Aims of trial: 166 BED-patients have practiced eating less food at a reduced speed at home over one week and a total of 354 BED-patients including the 166 patients have practiced eating in the same manner in Mandometer treatment of eating disorders. This trial aims at testing the hypothesis that BED-patients eat at a higher speed than normal weight, healthy control subjects. The trial also aims at examining whether BED-patients lose weight by practicing eating less food at a reduced speed. Normal weight, healthy control subjects will be recruited and tested for food intake and speed of eating at home over one week to meet these aims.
