When they don’t get enough sleep, women feel less full and men have a bigger appetite, according to a recent issue of the journal SLEEP. Twenty-seven normal-weight men and women (aged 30–45) were studied under short-sleep (4 hours) and habitual-sleep (9 hours) conditions. After a short night’s sleep, fasting blood samples indicated that fasting and morning ghrelin levels rose in men, while afternoon GLP-1 (glucagon-like peptide) levels fell in women. Sleep duration had no effect on insulin, glucose and leptin profiles.
