Normal weight adults, including those who had lost a lot of weight and kept it off, ate more often than overweight people in a new study looking at factors that may help in preventing weight gain.

Researchers following about 250 people for a year found that overweight individuals ate fewer snacks in addition to meals than people in the normal body weight range, but the overweight still took in more calories and they were less active over the course of the day.

“Most of the research has shown that people who eat more frequently have a lower weight,” said lead researcher Jessica Bachman, assistant professor in the Department of Nutrition and Dietetics at Marywood University in Scranton, Pennsylvania. “But no one knows why.”
