Obesity negatively impacts employers through increased absenteeism, presenteeism, and medical costs. Absenteeism alone costs employers $18 billion per year, while presenteeism accounts for $41 billion in lost productivity. Medical costs for obese employees are significantly higher than for non-obese employees, totaling $147 billion annually for employers. Combined, obesity costs U.S. employers $73.1 billion per year in excess medical costs and absenteeism.
