Late Sleepers Have Worse Diets Than Early Risers But sleeping late wasn't linked to higher BMI

DENVER -- Late sleepers who got at least 6.5 hours of shut-eye a night were more likely than early risers to have poor eating habits and they also tended to get less exercise, researchers reported here, although body mass index didn't seem to be affected. Late sleep timing in healthy subjects and late biological timing, measured by dim light melatonin onset (DLMO), were associated with higher fast food and lower vegetable and dairy consumption. However, calorie intake was not higher in study participants who slept late and showed late biological timing, and late sleepers actually tended to weigh less than those who woke earlier, researchers Kelly G. Baron, PhD, of Feinberg School of Medicine at Northwestern University in Chicago, and colleagues noted. http://www.medpagetoday.com/MeetingCoverage/APSS/58507?xid=nl_mpt_DHE_2016-06-14&eun=g721819d0r
