"Exercise Critical

to Weight

Loss"

A recent article in a major media outlet questions the effectiveness of exercise as a means of weight loss.

But it's a view challenged by five academics from a US university. "We want the public to know that there is no question the majority of research has proven that exercise, when combined with a healthy diet, results in both weight loss and maintenance of a healthy weight.

"The American College of Sports Medicine released an evidence-based position stand in early 2009 that proves these points.

"There is little evidence to the claim that exercising produces hunger so uncontrollable that it leads to weight gain. In fact a recent study from the University of Pittsburgh proved just the opposite: overweight and obese women didn't eat any more food after exercise than they normally would when sedentary.

"Exercise does require effort and self-control. However, the rewards are substantial.

"Economically, expenditures are reduced - the recent Weight of the Nation conference reported that obesity accounts for some $147 billion in health care costs per year - and people lead more enjoyable and energetic lives.

"Even for the non-overweight, exercise provides benefits that no pill or prescription ever could. It treats and prevents numerous chronic conditions, such as heart disease, high blood pressure, Type II diabetes and depression.

"Exercise is a health tool we all need, regardless of our weight. It is our hope that the public takes its importance seriously.

"Advice about weight loss should come from a qualified professional, instead of irresponsible articles that may not present the full realm of scientific facts surrounding the issue.
