Just in case anyone is interested in what obesity cost us as a nation in 1998, and the number of obese adults and children has risen since 1998, so we're probably paying a LOT more:
According to a study of national costs attributed to both overweight (BMI 2529.9) and obesity (BMI greater than 30), medical expenses accounted for 9.1 percent of total U.S. medical expenditures in 1998 and may have reached as high as $78.5 billion ($92.6 billion in 2002 dollars) (Finkelstein, Fiebelkorn, and Wang, 2003). Approximately half of these costs were paid by Medicaid and Medicare. The primary data sets used to develop the spending estimates for this study included the 1998 Medical Expenditure Panel Survey (MEPS) and the 1996 and 1997 National Health Interview Surveys (NHIS). The data also included information about each persons health insurance status and sociodemographic characteristics.

Insurance Category
Overweight and Obesity Obesity
MEPS (1998) NHA (1998) MEPS (1998) NHA (1998)
Out-of-pocket $7.1 $12.8 $3.8 $6.9
Private $19.8 $28.1 $9.5 $16.1
Medicaid $3.7 $14.1 $2.7 $10.7
Medicare $20.9 $23.5 $10.8 $13.8
Total $51.5 $78.5 $26.8 $47.5
Note: Calculations based on data from the 1998 Medical Expenditure Panel Survey merged with the 1996 and 1997 National Health Interview Surveys, and health care expenditures data from National Health Accounts (NHA). MEPS estimates do not include spending for institutionalized populations, including nursing home residents.

As shown in Table 1, in 1998 aggregate adult medical expenditures attributable to overweight and obesity is estimated to be $51.5 billion using MEPS data and $78.5 billion using 1998 National Health Accounts (NHA) data. For obesity alone, the estimated costs are $26.8 billion and $47.5 billion, respectively. The inclusion of nursing home expenditures in the NHA estimates causes most of the difference between the MEPS and NHA results.
