When You Eat as Important as What You Eat: Study

You are what you eat, as the saying goes. But new research shows when you eat, maybe just as important — if not more so — than what you eat.
In a new study published in the journal Science, researchers at San Diego State University and the Salk Institute for Biological Studies found that by limiting the time span during meals — and eating more earlier in the day and less into the evening — may prevent aging- and diet-related heart problems.
The research — which involved fruit flies but is belied to have implications for people, too — also identified that genes responsible for the body's biological clock are integral to this process, Medical Xpress reports. 
The findings echo past studies showings found that people who tend to eat later in the day and into the night have a higher chance of developing heart disease than people who cut off their meals earlier.
"So what's happening when people eat late?" said Girish Melkani, a biologist at SDSU whose research focuses on cardiovascular physiology. "They're not changing their diet, just the time."
Melkani and colleagues tracked the daily eating patterns of fruit flies to see if timing of meals could affect the heart health of the insects, which have long been used in studies to identify the genetic basis of human health conditions, including cardiovascular disease.
In their experiments, some flies was given a standard diet of cornmeal and allowed to feed all day long. A second group was allowed only to eat for 12 hours a day.
After three weeks, flies on the 12-hour feeding schedule slept better, didn't gain as much weight, and had far healthier hearts than the others — even though they ate similar amounts of food.
"Time-restricted feeding would not require people to drastically change their lifestyles, just the times of day they eat," said Melkani, adding that the results could one day translate into cardiac- and obesity-related health benefits for humans. "The take-home message then would be to cut down on the late-night snacks."
