Using similar methods to a previous study, Colditz estimates the direct costs of lack of physical exercise to be $24 billion per year (2.4% of national health care expenditures) and the direct costs for obesity, independent of lack of exercise, to be $70 billion (9.4%) for the year 1995.

Colditz reviewed the literature to estimate the proportion of type 2 diabetes, coronary hearth disease, hypertension, gall bladder disease, breast and colon cancer, and osteoporotic fractures that could be attributed to physical inactivity or obesity (BMI>30) in 1995.

According to Colditz's numbers, 69% of type 2 diabetes, 40% of coronary heart disease, 40% of hypertension, and 50% of gall bladder disease can be contributed to obesity (if I correctly understand population-attributable risk percent - PAR%).

The major contributors to the costs of inactivity were type 2 diabetes ($6.4 bil.), and coronary heart disease ($8.9 bil.).  The major contributors to the costs of obesity were type 2 diabetes ($36.6 bil.), coronary heart disease ($16.2), and hypertension ($7.6 bil.).

7.9% of the United States population is suffering from a form of Diabetes. That is over 23 million people! Now, more than ever, it is important for organizations such as yourself. We here, at (a site dedicated towards disease and their treatments), believe in the work you do and would like to coincide for the fight against diabetes. If you could, please list us as a resource or host our social book mark button, it would be much appreciated. Separately, we can make advancements, but together we can find a cure.
If you need more information please email me back with the subject line as your URL.

Thank You,
