This could be easy to remember: Dinner at 8 or even more late might not be great for your weight.  Researchers at the Northwestern University Feinberg School of Medicine saw that when they looked at meal times and sleep patterns in 52 people.

The study found people who went to sleep later had higher body mass indexes – ratios of their weight to their height – than did people who went to sleep earlier. And researcher Kathryn Reid says eating after 8 o’clock affected everybody:

``Regardless of what group they were in – whether they were a late sleeper or an early sleeper – if they ate eating after 8 p.m., they had a higher body mass index.’’ (7 seconds)

Reid says calorie-burning seems to be affected by people’s body clocks.

The study in the journal Obesity was supported by the National Institutes of Health.
