Exercise has most impact on weight

Exercise has most impact on weight

It won't shock anyone to know that Americans tend to gain weight as they get older. But it is a little surprising that as Americans age and put on more body fat, the quality of their diets generally improves.

In other words, Americans do try to correct their softening midsections with things like salads and lean proteins. And, unfortunately, that doesn't quite work, according to a recent analysis of physical activity, diet and weight among US adults. Instead, whether or not a person engaged in moderate to vigorous physical activity was more likely to predict their ability to stave off age-associated weight gain, Medical Daily wrote.

The study, which breaks down data points from 4,999 American adults ages 20 to over 70 years old, is large enough in sample size to depict an accurate snapshot of how Americans are aging, and how their diet and exercise levels change over the years.

"Our study points to the very important impact of physical activity on weight status in US adults, and in particular it points to the critical role of the age-related decline in physical activity on the increasing rates of overweight and obesity that we see with aging,” said lead researcher Russell Pate, Ph.D., of the University of South Carolina. "Our findings indicate that increasing fatness with age in US adults cannot be explained by changes in the quality of the diet they consume."

Overall, Americans’ activity levels are lower thanks to sedentary jobs, technology and better mass transportation options, according to the American Heart Association.

“We’re paying for those conveniences with our health; about 69 percent of adults are either overweight or obese, which increases risk for diseases like diabetes, cardiovascular disease, some cancers and reproductive problems.”
