Study: Late sleepers are less active and have a worse diet

EVANSTON, Ill. (WIVB) — Sleeping late may translate into trouble in the form of an unhealthy diet and a less active lifestyle.

Those are the conclusions of a new study being presented this week at a sleep conference. A team of researchers led by a professor from Northwestern University looked at roughly 100 healthy adults between the ages of 18 and 50. All of them slept 6.5 hours or more.

The team tracked sleep, food intake and calorie counts. They found that sleeping late does not necessarily lead to a higher body mass index, but it does lead to a worse diet, including more fast food.

Simple lifestyle changes could offer real results. The CDC recommends at least seven hours of sleep a night for people between 18 and 60 years old. Many health impacts come with lack of sleep. provides commenting to allow for constructive discussion on the stories we cover.
