The Osteoarthritis Action Alliance (OAAA) recently posted a recording of its October 17 "lunch and learn" event titled Energy Balance and the Obesity Epidemic. This 30-minute presentation by weight control and obesity expert Steven Blair, PED, FACSM, offers some possible explanations about the causes of the US obesity epidemic. Blair discusses some of his research on this issue, including his energy balance study, which revealed critical information about the relationship between diet, weight, and energy expenditure.
