"Could the Timing of When You Eat, be Just as Important as What You Eat?"

January 29, 2013

BWH Press Release:

Brigham and Women's Hospital announced a recent study led by Marta Garaulet, PhD, MPH from University of Murcia in Spain and Frank Scheer, PhD, MSc which found that the timing of meals predicts weight loss effectiveness, with late-eaters experiencing a slower weight-loss rate and than early-eaters. Late-eaters also lost fewer pounds overall than earlier-eaters, suggesting that the timing of large meals could be an important factor in weight loss programs.

The researchers studied 420 overweight people on a 20-week weight-loss treatment program in Spain. Early-eaters ate their main daily meal anytime before 3 p.m. and late-eaters, after 3 p.m. They found that late-eaters lost significantly less weight than early-eaters, and displayed a much slower rate of weight-loss. Researchers found that timing of the other (smaller) meals did not play a role in the success of weight loss. However, the late eaters—who lost less weight—also consumed fewer calories during breakfast and were more likely to skip breakfast altogether. Late-eaters also had a lower estimated insulin sensitivity, a risk factor for diabetes. These findings appear in the January 29, 2013 issue of International Journal of Obesity.
