I don't see how it could work monetarily for an HMO. A bicycle path is pretty expensive in the millions of dollars. It is used by only a small percentage of the population. An even smaller percentage of the population would derive a measurable health benefit. So the HMO would be spending millions of dollars in order to save hundreds of dollars. That is not a good move.

However, educating the people covered by the HMO about obesity, exercise, diabetes and heart disease could well be profitable. Also having seminars and intervention programs might also be profitable. However, most corporate executives are far more interested in cost cutting than in innovative programs that might actually work. So I don't think either would get support.
