It has long been known that what you eat plays a major role in weight regulation. Now new research has shown that when you eat may also be a big factor.
Researchers from Brigham and Women’s Hospital, University of Murcia and Tufts University studied 420 overweight participants in a 20 week weight-loss program in Spain. The study divided the subjects into early-eaters and late-eaters.
Both groups ate 40% of their total daily calories in one meal for lunch. The early-eaters had lunch before 3pm and the late-eaters after 3pm. The study showed that the late-eaters lost significantly less weight than early-eaters, and had a slower rate of weight-loss.
The remaining 60% of calories eaten during other meals did not seem to have any effect on weight loss results. It was found that late-eaters did consume less calories during breakfast or skipped breakfast entirely. They also had lower estimated insulin sensitivity, which is a risk factor for diabetes.
Lead author of the study Marta Garaulet, PhD suggests that “Novel therapeutic strategies should incorporate not only the caloric intake and macronutrient distribution, as it is classically done, but also the timing of food.”
