The sheer numbers associated with chronic disease, the magnitude of the medical and financial iceberg, make a mockery of this approach. The toll of the seven most common chronic diseases, in costs and lost productivity, was $4.2 trillion in the United States in 2012, up from $1.3 trillion in 2003.4 Chronic diseases account for more than 65% of corporate health-care costs. In a single year, there were almost 0.5 million new diabetes diagnoses for Americans ages twenty to forty-four, and 1 million new diabetics aged forty-five to sixty-five. Those are just the people who felt bad enough to see a doctor. The Centers for Disease Control estimate that 79 million Americans are pre-diabetic, which means their bodies are teetering on the edge of a disease that leads to blindness, kidney failure, nerve damage, and limb amputations if it isn’t controlled.5 Those people can be pulled back from the brink to some kind of normal future if they decide to make some significant changes in their lives. Unfortunately, 65% of employers in a large 2011 survey cited the difficulty of motivating employees to change their behavior as their top health-care challenge.
