“This randomized, controlled study is the first to show that bright light treatment during exercise impacted body composition by significantly reducing body fat after only a 6-week period.” Although the results of this study did not reach significance, there was evidence to prove that body fat composition was reduced with the implementation of bright light during exercise, despite the fact that body weight was not necessarily changed by the presence of light.
