BOSTON - Most weight loss programs seeks a balance between calorie intake and energy expenditure, but a new study published Tuesday in the "International Journal of Obesity," spotlights a necessary factor for weight loss : the schedule. Researchers at Brigham Women's Hospital, in collaboration with the Universities of Murcia and Tufts, found that not only what you eat but when you eat can help in weight loss and maintenance. 

- This is the first large-scale prospective study that demonstrates that mealtimes may provide effective weight loss - says neuroscientist Frank Scheer, director of the Medical Chronobiology Program at the hospital, an adjunct professor at Harvard Medical School and coordinator the study.

- Our results indicate that people who eat later showed an index of weight loss slower and lose less weight than those who eat earlier, suggesting that mealtime can be an important factor in weight loss programs - explains.

To validate the role of time feeding in weight loss, the researchers examined 420 overweight volunteers who followed a program for 20 weeks in Spain. 

Participants were divided into two groups, according to the schedules that fed, selected from the lunchtime considered the main meal of the day. During this meal, 40% of the day's calories were consumed. The group that ate early lunch before 15h and that fed later after 15h. The group later ate lunch lost less weight, more slowly, and still showed lower sensitivity to insulin, a risk factor for diabetes. 

The researchers found that the timing of other smaller meals had no role in weight loss. However, volunteers who ate lunch later also consumed fewer calories or failed to eat for breakfast.

Other traditional factors were taken into account in the research, such as caloric intake and expenditure, the hormones leptin and ghrelin, related to appetite, and sleep duration.
Among these factors, the researchers found no differences between the two groups, which means that the time the meal was a major independent factor in weight loss.
