Ways to stay active and healthy

Research

Move more: Too little exercise, not too many calories, is responsible for obesity among American teens, suggests a new study from the University of North Carolina at Chapel Hill.

Dr. Lisa Sutherland found that obesity among U.S. teens increased 10 percent from 1980 through 2000, while physical activity decreased 13 percent. Caloric intake increased only 1 percent.

"The decrease in physical education in schools, changes in transportation methods and popularity of television, video games and the Internet all contribute to an increasingly sedentary lifestyle for kids," said Sutherland, a clinical nutrition researcher. "Given these trends, it is crucial that we find new and creative ways to increase physical activity in adolescents as a first line of defense to combating obesity."

More research and new policies are needed to combat teen obesity, Sutherland said.

Overstuffed: Consumers who choose more food for only a little more money are probably short-changing their health, Penn State researchers say.

Super-sized restaurant meals lead to higher calorie intake. A related study showed that when individuals overate at one meal where big portions were served, they didn't compensate by cutting back the next day.

"The bigger portions that restaurants are providing make consumers vulnerable to overeating, since most individuals eat all or most of what is served. The excess food in mega portions is not going home in doggie bags. It is, instead, fueling the obesity epidemics," said Dr. Barbara Rolls, director of the study and Guthrie Chair of Nutrition at Penn State's College of Health and Human Development.

One segment of the study showed that consumers rated a standard-sized pasta meal and a larger portion that included a roll and vegetable the same for satisfaction and appropriateness of the portion size. The meals were priced the same, and consumers ate nearly all of the pasta in both size meals.

A second segment of the study showed that consumers given the same meals for two days for three consecutive weeks didn't cut back on calories during the second day of the study, even after portion sizes were increased.

The studies were presented April 12 at the Experimental Biology 2003 conference in San Diego. The National Institutes of Diabetes and Digestive and Kidney Diseases helped fund the studies.
