A lack of sleep could make you fat, scientists said on Thursday.
Not
getting enough shut-eye may inhibit a hormone which controls hunger
satisfaction and boost an appetite-stimulating hormone, said a paper
presented to the European Congress on Obesity in Lyon, France.
This, in turn, could increase the sensation of hunger by 25 per cent.
"If
this translates to a proportional increase in calories, then a person
with reduced sleep could eat 350 to 500 calories more per day," said a
statement on the research led by Karine Spiegel from the University of
Lyon.
A cheeseburger has about 500 calories.
The study
compared data from other research projects on obesity and sleep
duration. The findings are more pronounced for children and young
adults.
"While it might be natural to think that sleeping less
(or being awake more) means you use more calories and should therefore
lose weight, studies have shown the opposite to be the case," said the
statement.
"Interventions as simple as extending the nightly
sleep duration in these younger, habitual short sleepers should be
explored to prevent obesity."
Six hours are considered a short sleep period in adults and seven to eight hours a healthier one.
