A team of scientists in Minnesota has produced evidence implicating an unlikely culprit in the battle of the bulge: the household washing machine.
Researchers at the Mayo Clinic decided to test the idea that one cause of the nation's obesity epidemic is that household appliances cut down on the number of calories people burn in their daily routines.
"As the prevalence of obesity has increased, so has sedentariness. Progressive sedentariness has been attributed to greater use of labor saving devices such as washing machines," James Levine and his colleagues theorized in the Oct. 10 issue of the journal Obesity Research.
