There’s good news for those of us who love a lie-in: an extra hour’s sleep a night can shave 270 calories off a person’s daily diet – the equivalent of around three chocolate digestive biscuits. Over three years, this could lead to a weight loss of 1.8 stone, according to researchers at the University of Chicago and the University of Wisconsin-Madison. “Many people are working hard to find ways to decrease their caloric intake to lose weight – well, just by sleeping more, you may be able to reduce it substantially,” said (Esra Tasali, director of the UChicago Sleep Centre).

My comment: If you are sleeping you are not eating. O.K, but just cutting down on fattening food should have the same effect, and you can still have an enjoyable, rewarding life out of bed.
