Staggering cost of obesity

For a single individual, the burden of obesity can be enormous; for a society, the projected costs for health and economics are hard to fathom (Lancet 2011; 378: 815-25).

By 2030, this report projects that there will be 65 million more obese adults in the US and 11 million more in the UK.  This is expected to cause an additional  6-8.5 million cases of diabetes, 5.7-7.3 million cases of heart disease/stroke, about 500,000 cases of cancer, and loss of 26-55 milion life years.  The medical costs are estimated to increase $48-66 billion/year in the US.

These projections are based on expected increases in the percentage of individuals who are obese.  In 2008, approximately 32% of US adult men were obese based on BMI; in 2030, the projected number is 50-51% for men.  Among US women: 35% in 2008 –> 45-52% in 2030.

To flatten the curve on spending, we will need to look at flattening other curves.
