In 2000, the total costs (direct and indirect) attributable to obesity were estimated to be $117 billion, and between 1987 and 2001, diseases associated with obesity accounted for 27% of the increases in medical costs. Medical expenses for obese employees are estimated to be between 29% and 117% greater than medical expenses for employees with a healthy weight. In response, CDC has launched CDC LEANWorks!, Leading Employees to Activity and Nutrition, a FREE Web-based resource that offers interactive tools and evidence-based resources to design effective work-site obesity prevention and control programs, including an obesity cost calculator to estimate how much obesity is costing a company and how much savings that company could reap with different workplace interventions.
