Medline Plus, a service of the National Institutes of Health (NIH) and the U.S. Library of Medicine, recently released a video which talks about obese teen health and regular exercise. Once you are into the website, scroll down and look for the title 'New Hope for Overweight Teens' under the title of The Latest News.
Reported as part of Health day September 2009, this video states that a recent article published in the The Journal of Clinical Endocrinology and Metabolism indicates that exercise is beneficial for overweight teens even if they do not lose weight or even if there is no diet restriction. It was shown that even if no other changes are made, exercise prevents obesity-related associated medical illnesses such as Type 2 Diabetes! Great news for all since even lean teens receive this benefit from regular exercise!
