New research suggests the secret to maintaining a healthy weight could be as easy as turning off the lights at night.
Persistent exposure to light during the hours of darkness changes your metabolism and makes you pile on the pounds even without any change in the amount you eat. The researchers, from Ohio State University, also discovered that staying up later often led to a change in eating habits with much more food eaten at night when the metabolism is slowing down.
Study co-author Professor Randy Nelson said: "Light at night is an environmental factor that may be contributing to the obesity epidemic in ways that people don't expect.
"Societal obesity is correlated with a number of factors including the extent of light exposure at night.
"Something about light at night was making the mice (in one experiment) want to eat at the wrong times to properly metabolize their food."
The answer is keep the lights off then you won't see your way to the fridge. Simple.
