LACK of sleep can fuel obesity by preventing women from feeling full, new research shows.
The US study also found that men who failed to get a good night’s kip reported an increased appetite.
Boffins at Columbia Medical Centre studied 27 healthy volunteers — finding that restricted sleep affected levels of different hormones for men and women.
This is the first study in the area to differentiate between the genders.
Lead author Dr Marie-Pierre St-Onge said: “Restricting sleep in healthy, normal weight participants may affect food intake regulating hormones differently in men and women.”
The team measured hormone levels in the blood taken from the volunteers after sleeping for four hours and for nine hours.
Short sleep increased ghrelin levels in men but not women, and reduced GLP-1 levels in women but not in men.
Another study found that women who slept five hours or less per night weighed an average of 5.4 pounds more than those sleeping seven hours.
