Don’t skimp on shut-eye time!

That’s the advice if you don’t want to gain weight:

Want to avoid weight gain? Maybe some more sleep would help.

People who got very little sleep ate more but didn't burn any extra calories, according to a U.S. study in the American Journal of Clinical Nutrition that adds to evidence supporting a link between sleep deprivation and weight gain.

"If you're trying to control your weight, it would be helpful not to be sleep-deprived," said Marie-Pierre St-Onge of the New York Obesity Research Center at St. Luke's-Roosevelt Hospital, who led the study.

Although the most recent study, like other that have gone before, doesn't prove that sleeplessness causes people to pack on the extra weight, they do show that sleep should be a priority, experts said.

One is that sleep "seems to play a role in how your body manages the hormones that control how hungry you are, when you're hungry (and) what kinds of foods you're hungry for," said Michael Grandner, who studies sleep and sleep disorders at the University of Pennsylvania in Philadelphia.

Another explanation is that when people are tired, they may be less good at making healthy eating decisions.

Grandner added that it's possible the link goes both ways, and that eating too much of certain kinds of foods can disrupt a person's sleep schedule, or that somebody with a stressful job may sleep too little and also eat too much as a result.

Too little sleep has also been tied to a host of other health problems, including heart disease and diabetes, which have their own associations with weight, complicating the picture even further, he added.

The findings do show that "sleep should be a priority," he said.

I’ll try to go to bed earlier tonight.
