UNDATED (CNN) -- Is the sound of your alarm clock in the morning making you fat?
German
researchers at the University of Munich studied a phenomenon called "social jet
lag."
It's similar to jet lag when you travel. People can get "social
jet lag" when they wake up at one time during the week, and sleep in on the
weekends.
Scientists looked at people 16 to 65-years-old. They
discovered sleeping patterns, along with other factors, like age and gender, are
a good predictor of body weight.
One take-away from the study, according to
experts, is to try to maintain a regular sleeping schedule. It might be good
for your health in the long-run.
