NBC Nightly News (1/29, story 8, 2:10, Williams) reports, "According to the new research, which matches what some folks have been saying for some time, timing could be everything when it comes to sensible eating." Dr. Frank Scheer at Brigham and Women's Hospital said, "This was the first long-term, large-scale study to really show that the timing of meal is important in the success of weight loss therapy." Researchers examined 420 overweight Spanish women on the Mediterranean diet. Despite consuming the same number of calories, those who "had had lunch before 3 p.m., lost an average of 22 pounds in 20 weeks, five pounds more than those who ate lunch later."

(1/29) notes the International Journal of Obesity published the study, and the paper cites Sheer, who "says researchers don't know why weight loss was greater in the early eaters, but one hypothesis is that glucose (sugar) is processed differently depending on the time of day. Another theory is that the timing of meals can impact the circadian system (the body's clock) which may disrupt the proper function of the liver and fat cells." Dietician Elizabeth Ward, author of MyPlate for Moms: How to Feed Yourself and Your Family Better, "says this 'an interesting study, but it's an observational study, so it doesn't prove cause and effect.'"

The Los Angeles Times (1/29, Macvean) "Booster Shots" blog notes the study was led by M. Garaulet of the University of Murcia, who said: "Recent studies link energy regulation to the circadian clock...emphasizing that the timing of food intake itself may have a significant role in weight regulation."

Reuters (1/30) also cites Sheer, who said his team's findings suggest that, in the US, where dinner typically represents the largest meal, people who eat later dinners would have more trouble losing weight.

The Huffington Post (1/29) adds, "Of note for the Spanish study, the timing and content of the other meals didn't have an impact on weight loss, although late lunchers were more likely to either eat less at breakfast or skip it altogether. That is supported by additional research - skipping or under-eating breakfast is associated with eating a greater calorie consumption later in the day and with overall heavier weight."
