Obesity is among the most common diseases facing physicians. It is a major cause of premature mortality, with enormous economic impact on om society. A recent study estimated the annual cost of obesity in the U.S. as 93 bilhon per year, or 9.1% of all healthcare dollars, of which about half is paid by federal dollars. As frightening as these numbers are, they are based on 1998 data on the prevalence of obesity, and recent studies have indicated that the obesity epidemic has continued unabated, and the percent of adults with BMI >30 kg/m has increased from 18.3% to 22.5% in the 4 years from 1998 to 2002 (CDC, Behavioral Risk Factor Surveillance System).
