Medical economist Dr. Jay Bhattacharya at Stanford Medicine analyzed millions of medical records, and the factor that most correlated with increasing weight gain in the population was the number of visits to an HMO doctor. Now, that’s correlation, not causation, but you have to wonder. Back in 1970 we spent 6 percent of our GDP on healthcare, and now fifty years later we spend 17.9 percent. Yet the average American’s weight is up, health is down, and wallet is underwater.
