Eating later in the day may contribute to weight gain, according to a new study.
The week-long study included 31 overweight and obese adults, average age 36. Ninety percent were women.
They were enrolled in an ongoing weight-loss trial comparing daily caloric restrictions to time-restricted feeding, meaning they could only eat during certain hours of the day.
Participants wore an activPAL electronic device on their thigh. This device measured how much time they spent in physical and sedentary activities.
They also wore an Actiwatch, which assesses sleep/wake patterns. Participants were asked to use a phone app called MealLogger to photograph and time stamp all meals and snacks throughout the day.
The researchers found that on average, participants consumed food throughout an 11-hour timeframe during the day and slept for about 7 hours a night.
People who ate later in the day slept at a later time, but they slept for about the same amount of time as those who finished eating earlier.
Later meal timing was associated with a higher body mass index as well as greater body fat
