[单项选择]The obesity epidemic is being fueled still further by a growing trend among kids to eat out and bring takeout food home, University of North Carolina researchers say. Such foods are high in sugar and calories, and their increasing popularity means youngsters are getting more calories than they need, the researchers noted.
Since 1994, this trend has been growing rapidly and reflects the availability of fast food restaurants and foods prepared in supermarkets and other food stores, the researchers say. In fact, calories eaten away from home increased from 23.4% to 33.9% between 1977 and 2006.
"We found that kids eat a relatively maintained level of calories at home, but in addition kids also eat an increasing number of calories outside the home," says study author Jennifer Poti, from the university’s Gillings School of Global Public Health. "Eating outside the home is actually fueling the increased energy intake for kids." Poti says much of the foods children eat outside

[填空题]Obesity Epidemic
Ask anyone why there is an obesity epidemic and they will say that it’s all down to eating too much and burning too few calories. That is undoubtedly true. But it’s also true that we live in an "obesogenic (肥胖基因的) environment": calorific food is plentiful and cheap and our lifestyles are increasingly sedentary.
Now, obesity researchers are increasingly dissatisfied with such explanations. They believe that something else must have changed in our environment to cause such dramatic rises in obesity over the past 40 years or so. Nobody is saying that the "big two" -- reduced physical activity and increased availability of food -- are not important contributors to the epidemic. But they cannot explain it all.
Earlier this year a review paper by 20 obesity experts set out the 9 most plausible alternative explanations for the epidemic. Here they are.
Not Enough Sleep
It is widely believed that sleep is for the brain, not the body.

Obesity in children aged 2-5 has declined 43% in the last decade, according to Centers for Disease Control (CDC) data recently released in the Journal of the American Medical Association. Nearly 14% of young ones were considered obese in 2004 compared to a little over 8% in 2012. While this is undoubtedly a move in the right direction, obesity rates for older children and adults remain stalled (停滞).
The reason behind the drop isn’t clear, but several moves have been made in the last decade to combat the country’s growing weight, and many of the initiatives have focused on our youngest citizens.
CDC Director Tom Frieden says he’s seen "signs from communities around the country with obesity prevention programs including Anchorage, Alaska, Philadelphia, New York City, and King County, Washingt
