‘Lack of sleep can make you fat’

Mar 13, 2013 |

Sleeping only five hours a night and snacking more can make you add nearly a kilo in just a week, a new study has found. Sleeping just five hours a night over a week and having unlimited access to food caused participants in a new study led by the University of Colorado Boulder to gain nearly a kilogramme of weight.

The study, performed in collaboration with the CU Anschutz Medical Campus, suggests that sufficient sleep could help battle obesity. “I don’t think extra sleep by itself is going to lead to weight loss. Problems with weight gain and obesity are much more complex than that,” said Kenneth Wright, director of CU-Boulder’s Sleep and Chronobiology Laboratory.
“But I think it could help. If we can incorporate healthy sleep into weight-loss and weight-maintenance programmes, our findings suggest that it may assist people to obtain a healthier weight. But further research is needed to test that hypothesis,” Wright added.
