BLOOMINGTON, Ind. (UPI) -- Moderate-intensity physical activity such
as slow walking provides health benefits, but to lose weight some may
have to step it up, says a U.S. study.
"Although moderate-intensity physical activity does provide numerous
health benefits, such as reducing blood pressure and risks for
systemic inflammation and type 2 diabetes, you (should) increase the
intensity of your activity to lose weight unless you exercise more
than an hour almost every day," lead author Dong-Chul Seo, of the
Indiana University Bloomington's Department of Applied Health Science,
said in a statement.
The findings, published in the American Journal of Health Education,
said people who reported meeting the guidelines for vigorous physical
activity were less likely to be overweight or obese.
But there was no such relationship between people who met moderate
physical activity guidelines and their overweight or obesity status.
"Given the lack of evidence about the efficacy of moderate-intensity
physical activity on reducing body weight, health practitioners need
to be cautious against providing expectations that people could lose
substantial weight by engaging in moderate physical activity," the
authors wrote.
