Formal physical exercise programs for children have only a small
impact on overall activity and thus on weight loss, British researchers
report.
Their study raises questions about the best ways to help children attain or maintain a healthy weight.
"Physical activity interventions are not increasing physical activity

lead researcher Brad Metcalf, of the department of endocrinology and
metabolism at Peninsula College of Medicine and Dentistry in Plymouth,
England.
"It is in everyone's interest to find something that works
effectively," he added.
But other experts said instead of dismissing organized interventions
as ineffective, policymakers should conclude that still more is needed
to stem childhood obesity. In the United States, about 17 percent of
children aged 2 years and older are obese.
